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, sunflower seeds, rapeseeds, walnuts, cottonseeds, etc., often used in small and medium-sized oil plants, family oil workshop.
The screw oil press is divided into cold press screw oil press and hot press screw oil press according to the oil press process.
It can meet the various needs of users and can choose the suitable oil press equipment according to the oil press process.
Working principle of screw oil press:
Oil after passing into the hopper into the oil press, gradually in the bore by squeezing screw into the squeeze, squeeze spiral turn (using squeezer rotation changes pitch) make the material in the embryo to advance to squeeze, the pressing chamber under the condition of high pressure, embryo and squeezer, pressing chamber produces a great deal of friction between, so that the oil pressure, on the other hand, squeeze the rotation of the screw is constant gradually become bigger,Squeezer distance gradually become smaller, in this case, vats screw within the chamber and the relative movement of material, fuel and squeezed between itself and the oil chamber and the friction between heating oil press the heat generated by the thermal denaturation of protein in the oil, colloid, increased the plastic, but also reduce the viscosity, easy to outflow of oil and grease will gradually down the article oil press the row of gap flow out.
