One-level hot pressing is the most universal and widespread technology for oilseed processing. This technology is convenient not only for seeds with low oil content (soybeans), but also for oil-rich seeds, such as rapeseed and sunflower seed.
After pre-treatment and pre-heating, the seeds are turned into flakes in a flaking mill. This procedure is beneficial since flakes can be heated, dried, and pressed more effectively than seeds. After flaking, the mass flows into stack cookers, which serve for further heating and drying. Material prepared in this way allows much easier oil release in the subsequent pressing.
Naturally, the WP1 technology also comes with complete engineering and other services, such as technical support, service possibilities, and accessible spare parts.
Technologies delivered by Farmet are equipped with the visualization and control system Farmet Intelligent Control (FIC).
The sequence starts with a temporary container capable of supplying seeds for several hours of operation. Seeds are transported into the input heater, or a thermal stabilization unit, depending on the capacity of the press shop, before it enters the flaking mill. Here we also suggest you to enhance the procedure with a seed cleaning unit. It is also possible to supplement the technology with weighing equipment at entry, or hulling and hull separation.
Pre-treated seeds enter the stack cooker, where they are heated and dried up.
Seeds processed in this way are then compressed in the expeller press and oil emerges through the outlet slits. This oil still contains some impurities (solids) and has to be further processed with separation and filtration.
The technology of one-level hot pressing is a comprehensive solution for oilseed pressing. This technology is offered at capacities between 40 and 900 tons of seeds per day. The design routinely meets EU specifications; however, it can be adjusted to wiring requirements from local markets (e.g. USA, Canada, etc.).
The company Farmet offers optional accessories that will satisfy even the most demanding customers. Our delivery can be supplemented with a spectrum of funnels, conveyors, tanks, and equipment for seed pre-treatment as well as for pumping, filtration, refining and storage of oil. Nonetheless, the most convenient solutions are usually our turnkey deliveries, which are optimized from both the technical and economic perspectives, meet all your requirements and include the automatization of the entire process.
