How to improve soybean oil yield?

Soybean oil

Choose Dry Soybean and Well Prepared:You should choose dry and plump soybean instead of the wet ones. The soybeans should be sundried and removed the impurities like stones, snad, dusts etc.If the capacity is small, you can do it by yourself, but if the capacity is big, then you should think about the oilseed cleaning equipment help you do the job.
Well Control the Cooking Temperature:
Only in this way ,the oil is more active in the high temperature, the soybean seeds just out off the roasting machine when reaching 130o C, more oil can be obtained if oil is expelled at this temperature. The water content is about 1-2％，and the oil cakes is about 0.7—1-2mm.
Choose the Right Oil Press Machine:
The quality of soybean oil press machine has big influence on the oil yield. Mainly on the machine itself, it is pressure of press cage and temperature of screw shaft. Finally, high residual oil content on the cake. As we know, if the cake is too thick and high oil residual, we get less oil. So to get high oil recovery, we should try to get thinner cake in the oil press work.
