The technology of one-level pressing with extrusion is convenient of oilseeds with oil content between 16-25 %. The best example is soybean. The technology produces a high-quality, filtered oil as well as press cakes, which can be used as an adequate substitute for extracted groats. Moreover, thanks to their higher oil content (7 %), these press cakes have a comparably higher energetic value. Thanks to the process of extrusion, anti-nutritional substances are reduced, which will be appreciated especially by the producers of feed for pigs and poultry.
Do you want to produce cattle feed? We have also optimized this technology for increasing the nutritional value of soybean press cakes by increasing the relative content of by-pass proteins (proteins that are only slowly digested in the rumen).
This is a technology of one-level pressing with extrusion. The material is fed into the hopper and then into the extruder FE 500, where extrusion occurs. The resulting extrudate is carried on an inclined conveyor into the press FS 350.
The expelled crude oil, still containing solid particles, flows into the settling tank, where sedimentation of the solids occurs. The sediment is then separated out by an integrated separator and returned back into the press for another round of pressing. The settling tank contains an integrated oil heating system, which, together with solids separation, guarantees a high efficiency of the filtration process.
The Compact pressing shop can be further expanded with the Dehulling and Shell Separation module, which allows the separation of kernels from shells, where part of the shells is removed and discharged as a by-product. This is especially suitable for processing sunflower and soybean seeds. Removing the shells increases the protein content in the pressed cakes, thus enhancing their feed value. The shells can be processed using the shell granulation accessory, which transforms the shells into pellets, thereby reducing the volume required for shell storage and enabling their energy utilization.
Another optional accessory is Continuous Seed Weighing at the technology input, and for increased cleaning requirements, we recommend including a Destoner to separate stones and heavier impurities.
For treating the pressed cakes, it is possible to purchase Moisturizing of the Cakes with water or additives and Granulation of the Cakes immediately after pressing. For hot pressing technologies, we also recommend Cooling of the Cakes using a counterflow cooler.
The filtered oil is pushed out by a filtration pump and must be directed into a tank. We recommend supplementing with an Oil Storage solution, using plastic tanks with capacities of 1 m³ or 7 m³. The oil storage can be equipped with a dispensing pump that enables transferring oil from the storage tanks into transport containers or tank trucks.
The modular press shop Compact EP1 is offered at performances between 250 and 500 kg per hour (performance for soybean processing).
