There are many process methods for soybean oil machines, generally there are press method soybean oil machines and leaching method soybean oil machines. They also include soybean peeling and leaching oil production methods, flash evaporation dissolution method, negative pressure evaporation leaching oil production method, and puffing leaching method. No matter which method is used, the soybean soybean oil obtained has many impurities and cannot be eaten directly, and must be refined to obtain edible refined oil.
    The soybean oil machine's pressing method is divided into two types: ordinary pressing method and spiral pressing method. The common pressing method is a method of pressing on soybeans. Now this method is not used much, especially in industrial mass production. In the screw press method, a screw shaft is installed in a cylinder of a horizontal device, and the pretreated soybean enters the screw press; the oil is squeezed out while advancing.
    This method can be continuously produced, but in the process of oil pressing, the protein of the soybean press cake changes largely due to friction and heating. There is also a cold pressing method for cold pressing. Cold pressing is an oil production method of directly sending soybeans to a cold pressing machine for cold pressing. This method has a relatively low oil yield.
    Soybean oil machine's leaching method uses the solvent capable of dissolving soybean oil, sprays and penetrates the pretreated soybean raw materials, and uses the effects of molecular diffusion and convection diffusion to extract the oil from the material.
    Then, a mixed oil composed of a solvent and soybean oil is evaporated and separated, and the solvent is recovered to obtain a crude oil.
    The negative pressure evaporation leaching method of the soybean oil machine is a method of separating the mixed oil by using the secondary steam in the evaporator as the energy source of the first evaporator. The flash evaporation desolvation method is to use A, B pass and high temperature solvent gas to instantly heat the solvent in the meal to volatilize.
    Zhengzhou Dayang Company can design various processing schemes of soybean oil machinery and equipment according to customer requirements to meet the needs of different customers.
