Cold and hot pressing of vegetable oil from sunflower, soy and rapeseed — food-grade or technical oil, plus valuable protein cake as a by-product.
Two different pressing methods produce different oil types and different extraction efficiencies.
Pressing without heating the raw material — preserves nutritional values, antioxidants and aroma. Higher price, lower yield.
Heating raw material before pressing increases yield. Combined with solvent extraction in industrial plants.
Oil content, protein yield of the cake and market value vary by raw material — by choosing the raw material you target the market segment.
From cleaning and pre-treatment of raw material to pressing, filtering and full cake for animal feed.
Flattening grain before pressing — increases surface area and oil extraction efficiency. Key pre-treatment for soy and rapeseed.
Screw press for virgin oil without heating. Low temperature < 40°C preserves nutritional values and oil aroma.
High-efficiency hot press for industrial capacities. Heating increases oil yield to 85–92%.
Thermal treatment of soy before pressing — inactivation of trypsin inhibitors, increased pressing efficiency and cake digestibility.
Mechanical filtration of raw oil — separation of mechanical impurities and cake residues. Final step before storage.
By-product of pressing — valuable protein cake with 28–48% protein. Direct packaging or pelleting for animal feed.
