      • Our patented Romberger® Drying plants are individually designed according to your requirements built, adapted to your drying product and designed for the required capacities.
        We take into account all your specifications regarding emission limits and space requirements. To save overall height, the various drying zones can be arranged in two adjacent columns can be accommodated. We install your dryer in the open air or in existing Building in. Later conversions or extensions are possible at any time due to the modular design. Our experience helps you with advice, planning, assembly, instruction, approval, commissioning and lifelong service.

        Mode of action:

        We dry your grain gently and effectively. The Dryer is installed from above in equal layers filled with the product. The grain then slides through the shaft at intervals and gets into an air stream, which is blown through conical air conduction roofs, the grain is fed in and out washes around all sides and removes the moisture.
        The grain passes through the different temperature zones in cascade without damage. The warm air temperature of the product humidity always adjusted. In the lower The product is gently re-cooled before it leaves the dryer cooled and evenly dried by our special discharge device.

        Types: Continuous dryer and circulation dryer in one model.

        Product to be dried: corn, all cereals and oilseeds.

        Capacity: from 1 to 50 t/h. Other sizes on request.

      • Heat utilization for biogas plants

      • RST fermentation substrate drying for biogas plants
        • The amount of fermentation substrate is reduced by evaporation of liquid (0.7-1Kg/KW/h)
          • As a result, savings in storage capacity and transport logistics of up to 50% can be achieved
          • This amount is acknowledged at the fermenter volume capacity
        • The system is operated automatically with low maintenance and energy expenditure
          • We install the plant into your process with automatic filling and emptying
          • Thus, a continuous plant operation with full-year utilization is possible
        • The production of manure is possible by increasing the dry matter content up to 50%
          • Due to the evaporation of the liquid, the dry matter content of the liquid manure increases up to 12%
          • The nutrients per cbm increase accordingly
          • By means of the fume scrubber, the ammonia is bound with sulfuric acid. This results in a solid ammonium sulfate bond (ASL), i.e. liquid fertilizer
          • In the mixture with ASL, the manure then becomes a complete high quality fertilizer
        • The plant is operated dust-free
          • The fermentation substrate is reduced to a maximum of 12% dry matter content. As a result, there is no dust
          • The plant is operated with an exhaust air purification according to TA-Air, so there is no odor imission
        • You can use the complete waste heat
        • The machine is KWK-bonus able

        The performance varies with the available heat. Only time is affected.
        For example: at 600kW/h x 0,7L/kW = approximately 420L/h evaporated liquid.
        In an 8000h annual operation this corresponds to approximately 3360cbm liquid that does not need to be stored and transported.

        Function:

        The Romberger fermentation substrate drying plant increases the solids portion in the fermentation substrate by evaporation of liquid. Continuously heated contact plates in a rotating drum are immersed in the substrate. The moistened sheets are then fed into the air stream. The heated air flows through between the sheets and transports the evaporated liquid. By doubling the nutrient content due to the reduction in quantity, high quality manure is produced. In addition, the quantity reduction saves logistical costs, such as the discharge of manure or storage.

        The following points have to be proven for granting the KWK bonus:

        • The fermentation products must be prepared for the purpose of fertilizer production
        • The aim of the treatment is a weight reduction to improve the transport and storage capacity and a slurry upgrading
        • The plant is connected to a heat network of at least 400m in length
        • The plant is energy efficient and needs no more than 1500KWh (therm) to evaporate 1000l of water
        • The nitrogen must be less than 30%. The nitrogen contents of the products of an exhaust-gas/exhaust-air purification are subtracted from the difference and are therefore not counted as nitrogen loss.
        • The Plant must be notified to the competent authority
        • The amount of the fermentation substrate must be detected by a flow meter, the energy requirement via the heat meter
        • The TA-Luft must be maintained by means of exhaust air purification with an odor statement in ppm / cbm, and perhaps an odor report
        • The system must be coordinated with the responsible environmental expert

      • Shredder

      • Processing biomass with the Romberger Shredder DLZ

        • All substrates are continuously processed
        • The Romberger DLZ is always filled steadily
        • There is no need for constant switching on and off of the upstream dosing and conveyor system
        • With the Romberger DLZ you can shred all solid feedstocks to 100%. Manure, straw, corn silage, grass, sudangras, GPS, potatoes, sugar beet, all vegetable waste, grain maize, new substrates, etc.
        • Complex batch operations and peak current loads can be avoided with the Romberger DLZ
        • There are no complicated conversions of the existing system needed
        • The Romberger DLZ has an output of approx. 12to/h with corn silage at 55KW
        • The Romberger DLZ is absolutely immune to impurity and contaminants. What can not be crushed is ejected

        Function:

        • The constant and steady filling and emptying allows a trouble-free and low in wear plant operation
        • Fast rotating impact elements fray the biomass in a few seconds
        • Due to the special design of the Romberger DLZ the operation can be carried out continuously
        • The crushing degree can be changed by the number of impact elements

        The rapidly rotating shredding elements in the machine break up the cell structure of the biomass in seconds, thus creating a homogeneous substrate with a large surface. The Romberger DLZ frays the various input materials instead of cutting them. This increases the surface area of ​​the biomass and provides more attack surface for bacteria, allowing for faster and more efficient decomposition. The frayed substrate has a much better swimming behavior in the fermenter due to the higher fine fraction. This makes it easier to stir. The short structure thereby improves the stirring and pumping behavior.

        Use of previously unused substrates:

        Another important aspect that has so far received little attention is, in addition to increasing the yield of biogas through the pulping process, the Romberger DLZ generates the possibility of using materials that are currently difficult or not biogas capable, such as manure, grass, straw, landscaping or biowaste. Also new crops can be introduced and are safely controlled by the Romberger DLZ.
