Semi-automatic Soybean Oil Press

2016-08-05
Semi-automatic oil press equipment is one of  oil processing machinery, which is widely used for processing oil crops to eidble oil. The raw material can be sesame, rapeseed, peanut, cottonseed, soybean, seed, corn germ oil and other oilseeds crushing capacity. This oil press equipment is with simple and convenient operation, the oil production rate compared to other large oil extraction equipment.oil press

What is the working process of semi-automatic oil press?
 
The treated fuel into the good juice from bore semi-automatic press hopper. 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.
Thus the virgin bore in the press embryo each material 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 viscosity of the oil to the oil easily precipitate, thus improve the oil yield semi-automatic press, so that the oil in the oil squeezed out, and the discharge gap and the gap flow from the garden bar row.
