Pretreatment process feature:

1)        Different combinations of process can process various oil plants in one workshop.

2)        Use special intensified pretreatment technology for aroma peanut oil to make it more aroma.

3)        Adopt advanced and reliable shelling technology to meet higher requirements for protein content in meal.

4)        Extrusion treatment is used for raw materials with hard extraction, large-sized powder, and large capacity, which can reduce residual oil and solvent consumption, and increase the capacity by 50-80%.

5)        The new technology of shelling and low-temperature treatment can ensure high protein and least denaturation.

Main Paramaters

1.Deacidification
   Sodium hydroxide antagonize free fatty acids,and subside phospholipids,to remove the insoluble impurities,then after the separation of soapstock, neutral oil was washed in soft water,last drying in vacuum.
2.Decoloration
   Used to remove off pigments, bleaching oils and grease dehydrate

3.Deodorization  
   Using high temperature and high vacuum steam stripping method deodorization temperature commonly 180, vacuum degree 9.3 104 Pa can achieve ideal results 
4.Dewaxing 
   Dewaxing can ensure the colour of the oil to be clear bright at room temperature and frozen temperature. to reduce the oil in the wax content to 10 parts per million to get crystal clear oil.
