EP1 - One-level Pressing with Extrusion

One-level pressing with extrusion is a technology specially developed for processing soybeans. A combination of extrusion and subsequent expression will enable you to obtain press cakes of highest quality. Pressing the oil immediately after extrusion is highly effective and leads to minimal leftover fat.

Reducing the amount of anti-nutritional substances found in soybeans as well as increasing that of bypass proteins, in order to maximize the energetic value of the feed, is an easy job for our extruders. Extrusion is also an ideal way of pre-treating the seeds before the pressing itself. Indeed, a combination of mechanical and heat treatment better than extrusion can hardly be found. Material treated in this way is then efficiently processed in the presses, resulting in a high oil yield.

Naturally, the EP1 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).

Technology Description

The sequence starts with a temporary container capable of supplying seeds for several hours of operation. For operation in winter times, when seeds could potentially be exposed to temperatures below 15 °C, we recommend adding technology for temperature stabilization. Seeds are transported from the container continuously into the extruder. At this stage, we suggest including equipment for seed cleaning.

It is also possible to supplement the technology with weighing equipment at entry, or hulling and hull separation. Before extrusion, it is convenient to grind the seeds with a grinder, which will break up the seed structure, allowing easier passage through the extruder.

Extruded material is transported on a conveyor into the press. The conveyor is open to allow the steam, released after extrusion, to evaporate away. Due to a high amount of steam released, our offer comes with an extraction device that removes most of the steam coming from the extruder outlet.

Seeds altered 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 in separation and filtration.


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.

Technical Parameters

The technology of one-level pressing with extrusion is a comprehensive solution for oilseed pressing. This technology is offered at capacities between 6 and 600 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.).
