Soybean oil production line

Soybean oil is usually processed by pressing (oil press) and leaching (leaching equipment) to get crude oil with more impurities, and then refined to edible refined oil. Soybean oil content 15% - 26%, oil yield: according to the different quality of soybean, 12% - 18% (the oil yield of imported soybean is higher than that of domestic soybean), what are the soybean production processes? Follow the oil press equipment manufacturer Henan Zhongrui grain and oil machinery to understand it

The pressing method can be divided into ordinary pressing method and screw pressing method. Common pressing method is a method of pressing soybean oil directly. This method is not widely used, especially in large-scale industrial production. The screw press method is that a screw shaft is installed in the cylinder of the horizontal device, and the pretreated soybean enters the screw press; Squeeze the grease out as you move forward. This method can be used for continuous production, but in the process of extracting oil, the protein changes greatly due to friction heating.
