The dropping of seeds (cold or hot) plays a very important role in the process of seed processing and the production of vegetable oil. The collapse can be carried out using the technology of single-double collapse with husk separation or by the technology of double collapse with separation and with husk control. Depending on the physico-mechanical properties of the husk or shell, scourge or centrifugal rollers are used to bring down seeds.
When the seeds collapse, the core is crushed, which has a positive effect on the operation and especially on the productivity of the screw press. And since almost mostly pure kernels are pressed, the output is a high-quality oil with a low acid and peroxide number and with a unique taste and smell. In sunflower raw materials, with a decrease in the amount of husk, there are fewer accompanying substances such as wax, wax-like substances, free fatty acids, etc., which improves the commercial and consumer properties of the oil.
