                  • Even with today´s simulation techniques and computing power, pilot-sized process equipment is still indispensable for the development and refinement of new and existing products. During years of cooperation with companies in the pharmaceutical and chemical industries, HEINKEL DRYING AND SEPARATION GROUP has continually developed its tried-and-trusted pilot plant equipment which is already in use in many places worldwide.

                    The company is thus doing justice to increased requirements of industrial customers for safe handling, completely contained operation, flexibility and efficiency. The equipment meets the demand for devices suitable for use in potentially explosive areas in ATEX zones. The compact design of the pilot units facilitate transport from one place to another within the production plant – through narrow corridors and doorways or via lifts from one floor to another.

                    Heinkel Group supplies various centrifuge, dryer and filterdryer units which can be installed with minimum requirement in respect to installation and cost. The equipment can also be rented for short term and product specific testing. More information about test machines can be found > here.

                    Tests can be accompanied by our highly experienced process engineers, who will use test results for throughput calculations, up-scaling and documentation.

                                A large range of processes can be simulated, for example:
                                • Drying processes under vacuum
                                • Mixing processes
                                • Homogenisation

                                    As to the production of dry bulk materials which are produced after reaction, crystallisation or precipitation in suspensions, a combination consisting of a mechanical separating stage followed by a thermal separating stage will represent for almost all applications the best possible solution in consideration of product quality and economy.

                                    In order to ideally implement the combination of filtration and sedimentation equipment for dryers without any interfaces, the Heinkel Drying and Separation Group offers complete tailor-made solutions with all the necessary equipment from filling in the suspension to filling of the dried product.

                                    Our experts are in a position to select from our comprehensive product portfolio the best possible separating equipment combination for the respective task and supplement it through the necessary peripheral equipment thereby providing a complete solution.

                                    In doing so, our systems are based on a modular approach. Modules are available for every basic operation which, when combined, result in a unit without interfaces.

                                  • As the product price decreases, performance and throughput has the focus. The annual operating time and mechanical loads on the processing equipment increase, the operating conditions become somewhat rougher and satisfactory functioning under all these difficult conditions becomes a decisive criterion.

                                    This is why HEINKEL GROUP’s systems for such applications, although the same in principle, have a more robust and simplified version of some decisive components.

                                  • Food products

                                  • HEINKEL GROUP’s equipment has been used for decades in the production of food and health care products in the widest sense, provided that the products to be processed can be termed bulk goods, solids, solid particles or piece goods in any way. In many cases, products in powder or agglomerate form must be homogenized, mixed with additives, moistened and dried. Natural products such as cocoa, coffee or nuts must be subjected to heat treatment, extraction, sterilization or another process while constantly mixing them. Product mixtures must be degassed, dust-forming powders must be bound or in some cases roughly agglomerated.

                                    Applications
                                    • Food additives / ingredients
                                    • Vitamins
                                    • Health care products
                                    • Heat-treated natural products
                                    • Spices, herbs, tea, cereals, extract mixtures
                                    • Preliminary homeopathic product
                                  • Surface coating

                                  • Small parts, like in the automotive industry, can be relatively difficult to coat.

                                    HEINKEL GROUP can deliver centrifuges to ease this process. The parts are held by a spinning basket dipped in the vessel containing the coating. The basket is then elevated and the excess coating is removed by spinning.

                                    We offer an economical, reliable and heavy-duty machine.

                                    Applications
                                    • Coating of small parts
                                  • Metal / Recycling

                                  • The chips coming from the machining of metal parts are usually wet with lubrication oil. For obvious economic and environmental issues the oil has to be separated from the metal chips, typically steel, brass, aluminum, wood.

                                    HEINKEL GROUP can offer a continuous centrifuge to perform this task, where wet chips are fed into the unit while it is spinning and de-oiling. The dried chips are pushed to the upper part of the basket and fall down out of the centrifuge.

                                    We offer an economical, reliable and heavy-duty machine.
