Screw oil press is currently the most commonly used oil press for soybean extraction. The commonly used ones are 130 type and 120 type screw oil press.

Using a screw oil press to press domestic soybeans, the oil yield is about 13%-15%, leaving about 80 kilograms of soybean cake.

2,000 kilograms of soybean cake is needed, calculated based on the cake yield of 80%:

2000÷80%=2500

That is to say, the oil press presses the domestic Northeast Soybeans, it takes about 2,500 kilograms of soybeans to produce 2,000 kilograms of bean cake.
