  • Offer Profile
  • We plan, design, and build machines, complete plants, and turnkey production facilities for processing, conditioning, refining and pelleting of many different products for a wide variety of industries.

    AMANDUS KAHL today looks back on more than 140 years of machine and plant construction. In 1920, the first pellet mill designed as a worm extruder was produced. Our know-how in this field continues to develop, so that today we have gained international renown thanks to our flat die pellet mills. Worldwide subsidiaries and worldwide service show our steady and well-founded growth.

Product Portfolio
  • Pelleting

  • Pelleting - also referred to as granulation - is suitable for compacting product mixtures or individual components.

    There are no limits to the materials that can be compacted: from biomass such as wood or straw to pelleting of household waste and other recycling materials to the granulation of chemical and pharmaceutical raw materials.

    These substances and materials are pelleted using pellet mills. AMANDUS KAHL designs and manufactures pellet mills in different sizes and for different throughput capacities. Get informed here or contact us directly - together we will find the right solution for your project.

        • Pellet Mill

        • Particularly fine-particle or dusty products are often a challenge when it comes to storage. Both the porosity and the volume require special measures – also during transport. Our KAHL pellet mills help you to save operating, transport and above all storage costs. Products with different structures, bulk densities, binding strength and particle sizes are no problem for the flat die pellet machines. It is also irrelevant whether the products are powdery, fibrous, lumpy or pasty. The following products are mainly pelleted: Compound feed, raw materials and mineral mixes as well as by-products in flour and oil mills or malthouses. Also straw, wood, biomass and dried sludge (see sewage sludge).

          Applications and Advantages
          • The roller gap can be adjusted during operation
          • Permanently lubricated roller bearings prevent contamination by lubricating grease as well as grease losses
          • Quickly exchangeable pelleting tools
    • Conditioning

    • Our expanders, extruders and hydrothermal reactors ensure conditioning of the product.

      The KAHL annular gap expander is used in the production of feedstuff and it allows you to add fat, molasses, vinasse and fishsolubles to the product to be expanded.

      Our extruder OEE NG (New Generation) is used for the production of fish feed, shrimp feed and petfood.

      Hydrothermal reactors are used for the gentle pre-treatment and modification of raw materials such as legumes, cereals, soya and rape.

        • Expander

        • The annular gap expander consists of a thick-walled mixing tube with replaceable liners and cantilevered shaft which is provided with proportioning, mixing and kneading elements.

          The hydraulically adjustable cone at the outlet together with the outlet ring form the patented annular gap. By adjusting the cone during operation, pressure, kneading intensity, product heating and energy consumption can be controlled and programmed continuously and without delay.

          Applications and Advantages
          • Liquids, such as fat, molasses, vinasse and fish solubles, can be added to the expander in larger quantities
          • Expanded mixtures increase the press capacity
          • Pellet hardness and fines can be influenced by changing the parameters
          • On account of the precisely controllable process, value-determining ingredients are not damaged
          • Pathogenic germs, such as salmonellae or moulds, are eliminated by the treatment in the annular gap expander
        • Crown Expander

        • Two steps with one machine: The crown expander not only expands a product, but shapes it at the same time. This allows shaped products to be produced for all animal species.

          The expander technology is one of the best and most comprehensive conditioning methods for compound feed and individual components. The KAHL crown expander OEK facilitates the processing of feed mixtures.

          Applications and Advantages:
          • By using an expander you increase the capacity of the downstream pellet mill. Existing expanders can be easily modified to crown expanders. You will also benefit from the following advantages:
          • Increase of pellet quality
          • Increase of economic efficiency of compound feed production and reduction of costs
          • Higher press capacity
          • Use of components which are difficult to process

          • Operating temperatures at expander outlet between 90 and 140°C
          • Elimination of pathogenic germs such as salmonellae or moulds
          • Influence on pellet hardness and fines
          • The use of expanders promotes starch modification in grain components
        • Extruder for feed

        • With our extruder OEE 25 NG (New Generation) we provide the extruder market with fresh impetus. The highest level of engineering and professional further development of our existing extruder make operation even easier than before.

          After more than 20 years of experience with extrusion systems, AMANDUS KAHL has developed the extruder OEE 25 NG to meet the increasing demands of the fast growing fish and animal feed markets. The new extruder features AMANDUS KAHL stop bolt technology for ideal mixing and venting in the first cylinder section. Special process sections for compaction, cooking and kneading provide a high degree of flexibility and a wide range of setting options for processing feed. Exchangeable screw elements ensure perfect adaptation to different recipes and quality parameters.

          Applications and Advantages of the Extruder
          • Fast knife and die change
          • Distance between knife and die adjustable during operation
          • The new product family of the extruder comprises four different machine sizes
          • All sizes are available as individual machines or turnkey extrusion lines and include all process steps such as grinding and mixing, steam conditioning, extrusion, drying, coating, cooling and packaging.
          • The combination of individually adjustable screw elements and fine control measures makes it possible to meet the various requirements of our customers
          • No complex and expensive additional equipment is required for the extruder to influence the expansion behaviour. This allows our customers to save both investment and operating costs.
          • User-friendly machine
        • Extruder for food

        • The KAHL extruder OEE 8 offers the optimum solution for the production of food extrudates such as muesli flakes or snacks made of different cereals.

          For the production of instant food, AMANDUS KAHL supplies various machines for processing the desired product. While the KAHL flat die pellet mill can be used to produce pellets from food concentrates, snacks and muesli flakes can be produced with the KAHL extruder OEE 8.

          Applications and Advantages
          • Moderate investment costs due to the single-shaft extruder technology
          • Low energy and wear costs
          • Exact proportioning of solid matters, liquids, steam, and water
          • Optimum product conditioning through the use of a mixing conditioner, which, in addition to optimum mixing of the components, ensures treatment of the mixtures with steam if required
          • Extruder design with hydraulically moveable die which prevents blockages
          • As usual for KAHL machines, a quick die change is possible
          • Cooling or heating of the extruder thanks to the double-walled tubular case
        • Hydrothermal Reactors

        • Our hydrothermal reactors from KAHL offer gentle and uniform product treatment due to separately adjustable temperature, moisture, retention time, mechanical treatment and pressure.

          AMANDUS KAHL has many years of experience in the design of complete production lines in which different pre- and post-treatments can be combined with hydrothermal treatment depending on the requirements.

          Applications and Advantages
          • Gentle treatment
          • Low energy input
          • Controllable process steps
          • Wide range of applications
      • Crushing

      • Different individual components and product mixtures often require different pre-treatment. AMANDUS KAHL offers four machines for the field of crushing: the KAHL hammer mill, the KAHL crushing roller mill, the KAHL pan grinder mill, and the KAHL crumbler.

        Our hammer mill is appropriate for crushing individual feed components and feed mixtures. However, it can also be used for crushing cereals and biomass such as straw and wood.

        The KAHL crushing roller mill crushes feed mixtures, but also oilseeds and legumes. Unlike in the hammer mill which crushes the grain by impact, specific crushing takes place in this machine. 

        The pan grinder mills work according to the pan grinder principle and are used in wood processing. By means of the pan grinder rollers and the die, the product to be crushed is ground to a defined size.

        Our KAHL crumbler is used when coarse products such as pellets have to be crushed.

          • Crushing Roller Mill

          • Our crushing roller mill is used for crushing natural food and feed mixtures. The two counter-rotating rollers crush the respective product so that small particles are produced with low fines content.

            The structure of the animal feed is important for a successful animal nutrition. Our crushing roller mill is used to obtain a homogeneous and high quality feed structure. Its rollers break the feed into small and uniform particles so that a coarse granulate is produced instead of a mealy product.

            Applications and Advantages
            • We offer three different designs
            • You receive a narrow particle size distribution
            • The crushing roller mill features simple gap adjustment and easy roller change
            • Compared to our hammer mills, the power consumption is about 50% lower
            • You can count on low wear and smooth operation
            • Our crushing roller mill is particularly useful for crushing cattle, pig and poultry feed. But also for wheat, oats, peas, maize, rapeseed, barley, beans, lupins and soya
          • Pan Grinder Mill

          • Wood chips, sawdust or wood shavings as well as other lumpy biomass e.g. biogas substrate can easily be ground with our KAHL pan grinder mill.

            The raw materials differ in their surface, consistency, but also in their moisture content. Wood often has a higher moisture content than other biomasses, which can cause problems during grinding. However, pan grinder mills are adapted to precisely such biomasses and are therefore ideally suited for the grinding of wood products. The success is due in part to the crushing and grinding effect of the pan grinder rollers. The capacity ranges between a few hundred kilograms and over 40 t/h. The KAHL pan grinder mill achieves all this with minimum energy consumption in combination with silent operation, low space requirement and without aspiration system, cyclone, filter and exhaust air plant.

          • Crumbler

          • Our KAHL hammer mills are used for the grinding of feed components and mixtures, but also for all types of grain, straw, wood and similar products.

            In the feed industry, a distinction is made between the grinding of feed mixtures and individual feed components. The reason for this are the different surfaces and consistencies that can be found in the individual components of a feed mixture, while the individual feed components are largely homogeneous. For KAHL hammer mills, grinding of neither product is a challenge. This type of mill is also frequently used in grain processing. There are many reasons for this:

            The hammer mill is characterised by simple operation and handling. The machine works according to the principle of crushing by multiple impact, so that the most effective crushing takes place by the direct impact of the hammer mill beater on the product. The circumferential speed of the beater tip is approx. 360 km/h. Accordingly, screen perforations, beater designs, beater arrangements and speeds can be adapted to the structure and fineness of the end product. The final size of the grain is determined by the setting of the screen hole diameter and the mill speed. The product only leaves the hammer mill when it is smaller than the screen hole diameter - in approx. 95% of cases the products are smaller than half the screen hole diameter. 

          • Hammer Mill

          • The KAHL crumbler is characterised by smooth operation and low wear. The advantages of the crumbles clearly lie in the optimum feed conversion by the animal. KAHL crumblers are used for crushing pellets or coarse-grained products in the animal feed industry - more precisely in the compound feed industry. The finished product is broken or crumbled. Crumbling is carried out by corrugated rollers and different rotating speeds. This results in only a small amount of fines, which can be returned to the press after screening. In addition, the particle size range can be influenced by changing the spring preload.

            • Roller removal both to the front and to the side possible
            • Smooth operation, low wear and easy maintenance due to direct drive without chains, belts or gear wheels
            • One roller is spring-mounted
            • Roller gap and spring preload can be adjusted by means of screw spindles
            • The gap width can be read on both sides at the dial gauges
            • Additional remote control of the roller gap as well as the reversing flap settings by additional devices
        • Drying & Cooling

        • AMANDUS KAHL supplies various versions of the belt unit as well as fabric belt driers for drying or cooling of your pelleted products. KAHL offers belt driers, belt coolers or a combination of both. Our fabric belt drier is used in particular for drying wood pellets.
            • Belt Driers/Belt Coolers

            • More than 1000 KAHL belt units are in operation worldwide and work in different sectors. Before you decide on a belt drier, you have the opportunity to perform a belt drier simulation for your project in our pilot plant. Both cooling and drying are carried out according to the cross and counter current principle, depending on the number of belts. Due to the modular design of the belt units, they can be optimally combined to meet the required plant size. They are designed to suit both small and large units according to the modular principle.

              Applications and Advantages
              • Due to the simple design, subsequent extensions - depending on the version - can also be carried out without any problems.
              • Selection from several standard widths
              • Special widths also available
              • For the following industries: Feed, sugar, food, recycling, disposal, chemicals, brewery, energy, agriculture and biomass
              • For the following product shapes: Granulates, pellets, briquettes, lumpy, dusty and pasty products, expanded and extruded products and bulk materials
            • Fabric Belt Drier

            • Our KAHL fabric belt drier ensures optimum drying of the product as well as filtration of the exhaust air. The fabric belt drier is used in particular for drying wood.

              As the name suggests, the KAHL fabric belt drier is characterised by a tightly woven plastic fabric belt, which does not only dry the product but also filters the exhaust air to ensure that the legal limit value for dust fibres in the exhaust air is below the threshold value. Measurements by independent institutions have proven that the value is below the limit value - the average value was even far below half the permitted value. Discontinuous automatic cleaning of the belt avoids clogging of the belt openings with wood particles.

              Applications and Advantages
              • Use of a special plastic fabric belt which simultaneously serves as an exhaust air filter
              • Gentle drying by means of hot air
              • Individual adaptation to the desired product with adaptation to throughput
              • Requiring very low inlet air temperatures of less than 120°C, the fabric belt drier is particularly suitable to be operated with waste heat from cogeneration
              • Monitoring of the entire operation and process
              • Easy to maintain construction
          • Mixing & Conditioning

          • AMANDUS KAHL offer continuous mixers and mixing conditioners for the production of homogeneous mixtures from individual components.

            KAHL continuous mixers are used for all mixing tasks where liquids have to be continuously added to solids. This ensures a homogeneous ratio between solids and the added liquids.

            Our KAHL mixing conditioner, on the other hand, is particularly suitable for the production of feedstuff. Apart from the addition of water, steam and other liquids, the machine ensures the simultaneous thermal treatment of the product.

              • Continuous Mixer

              • With our horizontal and fast-rotating agitator-blade mixers, mealy, granular, fibrous and/or flaky carrier substances can be mixed with liquids.

                Our continuous mixer allows simultaneous addition of several bulk product flows, liquids and steam. Using the whirling principle, you can produce a lump-free mixture. The throughput time and the type of whirl formation can be influenced by adjusting the agitator blades. Thus the mixing effect can be adapted to the product. In addition, we manufacture the continuous mixer in four different sizes with a motor power from 7.5 to 110 kW, which provides a high variability in throughput time.

              • Mixing Conditioner

              • Our mixing conditioner "MK" enables you to condition feed mixtures or individual products with the addition of steam, water and liquids. Conditioning of feed is necessary to ensure the best quality in terms of nutritional properties. At the same time, the treatment serves as preparation for subsequent process steps such as pelleting. The mixing conditioner is ideal for an effective and economic mixing and heat treatment of feed. During conditioning, steam as well as water and other partly highly viscous liquids can be added to the input product with firmly defined ratio of retention time and throughput. A precisely defined degree of filling provides the best results with regard to adsorption and absorption of the additives. Optimum product treatment is thus achieved, with exact adherence to operating parameters such as temperature and water content. The shaft, case and mixing tools are made of stainless steel - for a long life and gentle product treatment. As an option, all components in contact with the product can be made of food grade materials.
              • Retention Conditioner

              • Our retention conditioner enables you to condition feed mixtures or individual components with the addition of steam and small quantities of liquid such as oil. In addition, our conditioner type "VK" ensures a determined retention time upstream of an extrusion process.

                Conditioning of fish feed, for example, is necessary to reach the best quality in terms of nutritional and physical properties. At the same time, the treatment serves as preparation for the subsequent (extrusion) process.

                Applications and Advantages
                • Selectable useful volume for optimised throughput (2 sizes)
                • Stainless steel design of all components in contact with the product
                • Electrically adjustable weir for continuous adjustment of filling level and retention time
                • Adjustable mixing tools to define retention time and mixing effect
                • Surface temperature sensor for measuring the product temperature
                • Large inspection openings for easy cleaning
                • Drive via slip-on geared motor
                • Suitable for meal feed or for conditioning upstream of extrusion
                • High degree of hygiene due to minimized dead spaces in the machine/apparatus
              • Conditioner

              • By adding steam, water, and other additives, feed mixtures or individual components can be conditioned efficiently with the KAHL conditioner "K". Conditioning of feed is necessary to ensure the best quality in terms of nutritional properties. At the same time, conditioning serves as preparation for, for example, the subsequent pelleting process.

                Applications and Advantages
                • Selectable useful volume for optimised throughput (2 sizes)
                • Stainless steel design of all components in contact with the product
                • Manually or electrically adjustable outlet slide for extended retention time
                • Adjustable mixing tools to define retention time and mixing effect
                • Surface temperature sensor for measuring the product temperature
                • Large inspection openings for easy cleaning
                • Drive via slip-on geared motor
                • Suitable for meal feed or for conditioning upstream of expansion and pelleting
                • High degree of hygiene due to minimized dead spaces in the machine/apparatus
            • Proportioning

            • Exact proportioning of the material to be treated is one of the most important preparatory steps for subsequent processing. AMANDUS KAHL designs and manufactures two proportioning machines for this process step, which ensure optimum proportioning of the product.

              Our KAHL screw conveyor is suitable for transport and proportioning of all kinds of bulk products.

              Our continuous cellular wheel weighers are used when powdery, mealy, fibrous or structured products have to be exactly proportioned.

                • Proportioning Screw & Conveying Screw

                • A simple design and low maintenance requirements - this is what distinguishes our KAHL proportioning and conveying screw and ensures a high level of operational reliability.

                  The proportioning and conveying screw is suitable for conveying bulk products of any kind in horizontal or ascending direction. Apart from our standard lengths of 1500, 2000, 2500 and 3000 mm, we also supply special lengths on request.

                  The worm shaft consists of a tubular shaft with welded-on solid thread (sheet steel). In addition, it runs on anti-friction bearings with stuffing box packing. If larger lengths are required, maintenance-free intermediate bearings are used. The tubular shaft parts are connected by means of bolts. The inlets and outlets can be arranged according to requirement. The proportioning and conveying screw is driven by offset geared motors - however, if space is limited, other drive types are also possible. 

                • Continuous Cellular Wheel Weighers

                • Our continuous cellular wheel weighers are designed for measuring and recording mealy, powdery, fibrous and structured products.

                  The AMANDUS KAHL continuous cellular wheel weighers offer precise measurement of bulk materials with a wide range of surfaces. Our load cells continuously measure the weight of the filled cellular wheel and thus an instantaneous weight of the varying product flow. Mealy, powdery, fibrous or structured products can be measured and/or weighed with an accuracy of ± 2%.

              • System Control

              • In order to make the operation of our machines as user-friendly and simple as possible, AMANDUS KAHL has developed various control systems. They include the electrical control system of our expander (ESEP), the automatic control of our flat die pellet mill (EAPR) and the adjustment of a constant roller gap during pelleting (DISTAMAT). ESEP ensures full automation of the complete expander line and a constant product quality.

                The EAPR system ensures fully automatic operation of your pellet production. In addition, our DISTAMAT system provides a constant distance between the pan grinder rollers and the flat die.

                  • EAPR – Automatic Pellet Mill Control

                  • Automation is in the focus of KAHL systems. We have developed the EAPR and DISTAMAT for the automatic control of our KAHL flat die pellet mill.

                    The EAPR from KAHL consists of a local control cabinet with graphic touch panel (TP) and a PLC with Step 7 CPU as central components. It thus controls and regulates all relevant process parameters. As an option, the DISTAMAT can be used for continuous adjustment and regulation of the roller gap, as good pellet quality requires a constant roller gap. Our EAPR and DISTAMAT systems therefore ensure optimum press operation combined with low manpower requirements.

                    Applications and Advantages:
                    • One control system for all press types and sizes
                    • Good visualization through the use of pictograms
                    • Fully automatic operation according to the preselected process parameters
                    • Minimized downtimes
                    • Storage and display of process data or error and alarm messages
                    • Control and monitoring of the pellet mill, proportioning screw, mixer, auxiliary units as well as the cooler and the upstream and downstream conveying elements as required
                    • Control of the pellet mill (load dependent), the throughput in t/h, the steam and the liquid. Optionally, up to four liquids can be added additionally to the mixer
                    • Simple operation and control using the touch panel
                    • Error and alarm messages
                    • System diagnostics
                    • Remote maintenance of the PLC controller and assistance in case of problems by the KAHL Service Team
                    • Video monitoring of machines
                  • DISTAMAT - Automatic Distance Control

                  • Depending on the setpoint deviations, the pressure of the hydraulic system of the pellet mill is controlled in such a way that the roller gap is kept constant. In this way, our DISTAMAT allows a continuous preselection of the roller gap. Apart from that, the direct contact of die and pan grinder rollers which usually results from a product shortage is avoided. Thus service lives of pan grinder rollers and die are considerably increased. By means of alternating lifting and lowering of the pan grinder rollers, the optional unblocking programme causes an automatic unblocking in case of an overfilling of the pellet mill.

                    Applications and Advantages:
                    • Continuous adjustment and control of the roller gap
                    • Higher and more constant pellet quality
                    • Minimized wear of the die
                    • Simple retrofitting
                    • Simple unblocking of the pellet mill (optional)
                    • Error and alarm messages
                    • Remote maintenance of the PLC controller and assistance in case of problems by the KAHL Service Team
                  • ESEP (Electrical Control System of the Expander)

                  • Our ESEP is an automation concept that makes optimum use of the potential of the annular gap expander and far exceeds simple machine control. The ESEP was developed for the simple control of our annular gap expander and now contains more than twelve years of process and automation knowledge. It consists of two essential components - the switch cabinet with Siemens PLC S7 and the PC-based visualization and operating station. The actual control and regulation of the process takes place at the switch cabinet. Therefore, the cabinet should be close to the machine. The visualization and operating station represents the interface to the operator and is implemented using Windows and Intouch (Wonderware).

                    Applications and Advantages:
                    • Full automation of the complete expander line
                    • Constant product quality at high throughput
                    • Low manpower requirements
                    • Visualization of up to three lines on one PC
                    • Improved monitoring of the production process
                    • High availability due to the use of proven quality components
                    • High process flexibility, adjustable and extensible without any problems
                    • Rapid and economic commissioning
                    • Field bus system saves installation costs
                • Refining

                • Refining is part of the final processing of your products. AMANDUS KAHL offers two machines for different processes. Our vacuum coater forces liquids, enzymes or vitamins into the interior of your products using a vacuum. Different active ingredients can be successively introduced into the product. In contrast, our Rotospray® acts on the product surface. With this device, liquids can be applied to the product or its appearance can be refined.
                    • Rotospray®

                    • The KAHL Rotospray enables you to refine your end products using liquid additives: Add more ingredients to your product or refine its appearance.

                      Our KAHL Rotospray is a micro-spraying system for the application of liquid additives to the end product. The rotation nozzle allows ultra-fine spraying of liquids on solids: 1 millilitre of liquid is diffused into 10,000,000 droplets. The special distribution of the solid matter flow ensures spraying of the product from all sides.

                      Applications and Advantages
                      • Low space requirement
                      • Automatic adjustment of the liquid flow to the solid matter flow
                      • Undiluted spraying
                      • No remainders of liquids
                      • No spoilage
                      • Insensitive to dust
                      • No danger of clogging
                      • Unpressurized liquid supply
                      • Thrifty coating
                    • Vacuum Coater

                    • Increase the quality and/or the energy content of your feed and introduce liquids deep into the pores of shrimp and fish feed, pellets, extrudates, poultry feed and pet food. Vacuum coating is a standard process in fish feed production. Depending on the feed type, 4 to 40 % oil are subsequently applied to the extruded fish feed.

                      As this process results in excellent product quality, the vacuum coater is also used in the production of dog and cat food. The process is also increasingly being used in the field of compound feed production, particularly poultry feed. The subsequent addition of fat significantly increases the energy content of the feed, allowing high-fat compound feed components to be minimized in the formulae. This reduces the costs for the raw materials. Low-fat feed pellets often have significantly better qualities (e.g. abrasion resistance).

                  • Fluidized Bed Technology

                  • With fluidised bed processes, the product properties of powders or granules can be specifically changed and optimised according to the customer requirements - and they can bring liquid products into a solid form.
                    As a specialised plant manufacturer, we work together worldwide with customers in demanding industries such as the food industry, the fine chemicals, the chemical and pharmaceutical industries as well as the biotechnnology.
                      • Batch FB - Fluidised Bed Plants for batchwise processing

                      • For processing powdery substances and for shaping liquids, the fluidised bed technology provides optimum solutions to reach efficient production processes. Contrary to continuous fluidised bed plants, batch-wises processes take place consecutively. They are reproducible at any time and ensure a high product quality. The batch technology is an alternative, when fast throughput times do not matter and fixed batch sizes are to be processed or when a frequent product change is planned. AMANDUS KAHL fluidised bed plants are versatile and flexible. They can process a variety of products and refine powders, granules or pellets or shape liquids to particles.

                        Examples for the application of the batch fluidized bed technology
                        • Agglomeration of instant drinks such as cocoa, fruit drinks
                        • Microencapsulation of vitamins or probiotics
                        • Spray granulation of fertilisers
                        • Agglomeration of instant soups and sauces
                        • Uniform drying of pharmaceutical active ingredient mixtures or wet granulates
                        • Granulation of pharmaceutical tablet mixtures
                        • Fat Coating of food or feed products
                      • Conti FB

                      • The continuous fluidised bed technology offers ideal possibilities for a targeted modification or customised optimisation of the product properties of bulk goods. In continuous fluidised bed plants, the processes are fully automatic. They are reproducible at any time and ensure a high product quality. Unlike batch plants, the product passes through several zones in one apparatus, in which run various processes such as agglomeration, granulation and drying take place simultaneously.

                        Examples for the use of continuous fluidized bed technology
                        • Agglomeration of instant drinks such as cocoa, fruit drinks
                        • Spray granulation of calcium lactate
                        • Agglomeration of baby food
                        • Spray granulation of fertilisers
                        • Agglomeration of curry powder
                        • Agglomeration of instant soups and sauces
                        • Uniform drying of pharmaceutical wet granules or pellets
                        • Drying and cooling of plastic granulate

                        • Agglomeration of special flours
                        • Spray granulation of ceramic slurry
                        • Continuous layering processes
                        • Encapsulation of flavourings
                        • Gentle drying/spray granulation of fermentation products
                      • Laboratory Plants

                      • We offer high-performance laboratory plants for continuous and batch-wise processing in different versions. Our laboratory apparatuses help you to improve your processes, to define parameters, to test recipes and to optimise product handling before starting mass production. Carry out feasibility studies, develop special substances and innovative products – a safe scale-up of the results provides your R & D department with all options for conducting a low cost, successful project management and supports you in every phase of production.

                    • Industries

                        • Compound Feed Industry

                        • We classify them into compound feed plants, fish feed plants and plants for pet food. All Kahl compound feed plants are 100% produced at the central factory in Reinbek near Hamburg. With more than 140 years of experience, the company is one of the most competent manufacturers of compound feed factories and plants for use in the compound feed industry. In the category "Compound feed plants" you will find conditioners, pelleting presses, expanders and many other machines.
                        • Biomass Industry

                        • For the processing of biomass for energy recovery, AMANDUS KAHL offers its customers pelleting plants for two different sectors. The pelleting of wood is one of these areas in which AMANDUS KAHL has almost 50 years of expertise. We manufacture state-of-the-art plants for the production of premium quality wood pellets, as the wood sector in particular is becoming increasingly important when it comes to recovering energy from renewable raw materials.
                        • By-Products Processing

                        • By-products are defined as secondary products derived from the actual treatment and processing of the main product. AMANDUS KAHL specializes, among other things, in the pelleting of green waste and alfalfa, sugar beet pulp, bran and oil press cake - all by-products that require a high-quality and reliable pellet mill. Pelleted green waste offers a particular advantage in the storage and transport of the otherwise quite voluminous material and serves as a special source of nutrients for animal feed.
                        • Recycling Industry

                        • Sustainability and recycling are becoming increasingly important issues. "What happens to the waste produced?" AMANDUS KAHL plants provide the answers to these questions.

                          AMANDUS KAHL offers plants for pelleting municipal and domestic waste and sewage sludge. Furthermore, we plan, manufacture and build waste tyre recycling plants. Domestic waste and sewage sludge are characterised by a high storage volume and a low bulk density. Pelleting the materials is a convenient solution to both problems. Pellets from domestic waste and sewage sludge are ideally suited as an alternative fuel and conserve other resources. Several processing steps are required prior to pelleting domestic waste or sewage sludge. From the very first minute, KAHL will assist you in planning your project.

                        • Chemical Industry & Pharmaceutical Industry

                        • Our well-proven pelleting process is also ideal for the pharmaceutical industry, where it is particularly important to achieve a concentration of active ingredients. Chemical and pharmaceutical pellets facilitate exact dosing. For the pelleting of chemical and pharmaceutical substances we have developed variable machines and press types which cover different throughputs and are individually equipped. We offer solutions for many different bulk materials. Our small flat die press is particularly suitable for small-scale production of pellets from powdery and lumpy products. It convinces by low installation costs and the production of particularly high-quality products. The press type 14-175 ensures efficient dry granulation of the tablet mass for the subsequent tabletting process.
                        • Fluidized Bed Technology

                        • A fluidised bed is formed when a gas (generally air) is passed through a quantity of solids from the bottom. The particles are intensely moved and a so-called fluidised bed is formed. Now there are perfect preconditions for the heat and mass transfer and thus for cooling or drying of fluidisable bulk goods. Via integrated spray systems, the fluidized bed method can be used for further process technological procedures. Fine powders or liquids, for example, are formed to particles by agglomeration or spray granulation and then show enhanced application properties as granules. Moreover fluidized bed processes are suitable for coating and micro-encapsulation of active substances.
