Pre-treatment of oil-bearing material means material cleaning, husking, peeling, breaking, softening, flaking, puffing, heat-moisture treatment and drying before pressing, to remove impurities and make it to be certain structural performance to accommodate different oil press technology. Based on different oil materials and oil extraction technology, the way of pre-treatment is different, either. The way of pressing is driven by mechanic force to press oil. There are two types of extraction technology – pre-pressing and pressing, and pre-pressing is a traditional way of processing on oil material of high oil content. 

Oilseed pretreatment and pre-pressing    Specification: 10-100/D

Application scope: This pre-treatment extraction technology is applicable to kinds of oil-bearing material, such as peanut, rapeseed, sunflower seed, castor bean, maize germ, tea seed, rice bran, sesame, etc.

Our company's pretreatment technology has the following features:

1. Adopting the different process combination,  in one workshop can pre-treatment  a variety of oil materials. 
2. To aroma peanut oil, use special  pretreatment technology  to strengthen the  fragrance, and make it more fragrant.
3. If has a higher requirement about the protein content of the cake, we use the advanced technology and reliable peeling.  
4. Raw material which Leaching difficultly, big powder or request higher production, we use Puffing treatment, reduce the residual oil and solvent consumption, improve yields to be 50-80%.
5. Peeling and low temperature new technology, can guarantee the high protein content and least degeneration.
