From Seed to Seed Oil

When the press operation, the processed oil from the hopper into a good squeeze bore. Pressed by the screw turn make the material to keep the embryos in advance, be pressed. Since the parison in the press bore is squeezed in the state of motion, pressing bore under high pressure conditions, resulting in a lot of friction between the material and the pressing screw embryos, embryos and virgin material bore, thus make friction, resulting in relative movement between the micro-parison material. On the other hand, due to the pressing screw root diameter is gradually thickening Park pitch is gradually reduced, so that when the pressing screw is rotated, the threaded hard parison that is able to move forward, but also to turn outward, and close to pressing screw thread as the surface layer material further pressing axis. Such virgin bore in each parison particle velocity is not the same direction, but also exist between particles relative motion. Heat generated by the friction but also to meet the oil extraction process operation necessary calories, help to promote parison thermal denaturation of proteins, damage colloid, increased plasticity, but also reduces the stickiness and some oil to easily precipitate, thus improve the oil yield of the press, so that there is oil squeezed out of feed and discharge slit strip and exhaust flow from the slit garden.
