100 kg of soybeans can probably press 12-18 kg of oil, different kinds of soybeans and their oil content also has a certain difference, usually, soybean oil content is 16-22%.
The oil content of the soybean itself determines the oil yield, but in addition to the oil content there are two other factors that have a greater impact on the oil yield, that is, the method of oil extraction and oil extraction equipment. There are two common methods of oil extraction in the industry, physical pressing and solvent extraction, and there are both large and small oil extraction equipment.
Large soybean oil production line will be a small oil press machine to extract more oil, because soybeans after cleaning, peeling, flaking, cooking and a series of pre-treatment, the temperature of the oil seed, humidity, granularity, etc. will reach the best oil state of the multi-air fluffy, at this time the oil circuit is open and then oil can be extracted to more oil, or even twice as much as a single machine.
Hexane solvent extraction method than the physical pressing method to extract more oil, physical pressing after the soybean cake still has a lot of oil residue, large-scale crushing plant will choose to further extract the residual oil in the cake after pressing, at this time it will use the solvent extraction equipment to extract oil. Solvent extraction equipment can make the lowest oil residue, after extraction equipment for oil, soybean cake meal in the residual oil rate of less than 1%.
Of course, there are many factors that affect the oil, you want to know more about the oil and grease issues welcome to consult the Siwei oil engineering, we are professional, will answer your questions.
