How to choose the suitable oil press equipment according to the oil pressing process?
Spiral oil press is a new type of oil press equipment, it is mainly used to press a variety of oil, such as peanuts, soybeans, oil sunflower, rapeseed, walnut, cottonseed, etc., often used in small and medium-sized oil plants, family oil workshop.
Screw oil press is divided into cold press screw oil press and hot press screw oil press according to the oil press process, which can meet the various needs of users, and can choose the suitable oil press equipment according to the oil press process.
Oil through the hopper into the oil press, gradually by the press screw into the press chamber, the press spiral turn (using the change in the spin of the press screw pitch) make the embryo constantly push and press, under the pressure of the press chamber, between the embryo and the press screw, press chamber produced a lot of friction, so that the oil is under great pressure, on the other hand, the press screw is constantly rotating gradually larger, The distance between the pressing screw gradually decreases, in this case, the pressing screw and the relative movement of the material inside the pressing chamber, the oil itself and the friction between the oil and the pressing chamber and the heat generated by the oil press heating make the protein in the oil thermal denaturation, destroy colloid, increase the plasticity, but also reduce the viscosity, easy to flow out of the oil, gradually the oil along the oil press row gap flow out.
Matters needing attention in the run-in period of screw oil press:
1. Try to eat rapeseed or rapeseed cake as the main mill material, and it is forbidden to only use sesame cake and peanut cake as mill material.
2. If the oil press is stuck during run-in, it is necessary to stop and clean the foreign matter before run-in can be carried out again.
3, during the run-in period, it is forbidden to feed too fast, and try to grasp the feeding by hand, so as not to cause stuffy machine.
