The technology of one-level cold pressing is based on a single pressing step. No mechanical or heat treatments are involved; the seeds are fed directly into the press.
Advantages of one-level cold pressing are lower energy demands, simple machinery and its installation, and small size, together significantly reducing investment costs. This technology does not require a source of steam. It is also very careful with processed material; resulting cold pressed oil is a high-quality “virgin” substance, low on phospholipids.
The sequence starts with a temporary container capable of supplying seeds for several hours of operation. For operation in colder environments (in winter), 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 first-level presses. 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. The seeds are compressed in the press and the resulting oil still contains some impurities (solids) and has to be further processed with separation and filtration. The cakes are carried on a conveyor into storage space.
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.
The technology of one-level cold pressing is a comprehensive solution for oilseed pressing. This technology is offered at capacities between 3 and 170 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.).
