1 conventional production process: raw materials - steamed fried - press - machine pressed crude oil
(2) Special grease production process: Oilseeds - Broiling - press - filter - fragrance oils
Three special oil production process: Oilseeds - whole seed cold pressing - filter - cold-pressed oils
Fuel oil is squeezed out of the process: When the fuel into the oil press machine virgin bore, with the pressing chamber rotates, the pressure increases. As the seed material extruded continuously squeezing oil, virgin material particles in direct contact with each other and cause a pressure deformation of seed material, particularly in the oil film rupture and the adhesive body. Such bombing bore hydraulic oil press after being squeezed, squeezed material is not a loose body to form a plastic body, hydraulic oil press the cake. Squeeze due to the dual role of temperature and pressure, will continue to deteriorate protein, thereby affecting virgin cold oil press  material, in short, in order to ensure an appropriate level of protein denaturation best squeeze out the oil effect.
