30tpd soybean oil refinery plant
The process of soybean oil refining is to refine the crude soybean oil, to remove gossypol, protein, phospholipid, grume, moisture and other impurities, in order to reach the purchase of food and storage.
According to different raw materials, the process of cooking oil refining includes mechanical refining method, chemical refining method and physical refining process refining process.
Main process of soybean oil refining machinery:
1. Crude soybean oil degumming process,
2. Crude soybean oil deacidification/neutralization process
3. Crude soybean oil decoloring process
4. Crude soybean oil deodorization/distillation (deodorising unit) process
Machines of soybean oil refining line:
 Degumming machine |  Deodorization tower |
 Crystalling tank |  Dewaxing press filter |
The application scope of soybean oil refining machinery:
Our soybean oil refining machinery is also suitable for refining other crude vegetable oil. Such as crude soybean oil, crude palm oil, crude peanut(groundnut) oil, crude rapeseed oil, crude rice bran oil, crude corn oil and other crude edible oil.
Oil seeds
 Rice bran |  Peant |  Soybean |
 Rapeseed |  Palm seeds |  Corn germ |
Above oil seeds and other oil seeds can be extracted by our oil refining machine.
The national standard of refined cooking oil:
Refined oil products
After soybean oil refining machinery the crude soybean oil will become the high grade soybean oil, good for human body, no matter the smell, taste and color, the refined soybean oil will become superior cooking oil, first grade soybean cooking oil.
