Oil Seeds Pretreatment Line
1. Oil Seeds Pretreatment Line: The purpose of this line is to adjust the oil seed and improve the oil yield rate. After pretreatment, the quality of final oil is better. Usually the pretreatment line includes cleaning, shell flaking roller, cooker or press. For different kind of oil seeds, the process of pretreatment is different.
Crude Oil Making Line
2. Crude Oil Making Line: After pretreatment, the oil seeds are sent to crude oil making machine to get crude oil. There are two ways to make crude oil. One is pressing way. This way is suitable for high oil content seeds. The other one is solvent extraction way. This way is suitable for low oil content seeds. According to the oil content of oil seeds, we can suggest the adjustable way for you.
