Bleaching is the process operation which removes colouring matters by mixing bleaching earth with oil under controlled conditions of temperature. After proper mixing with bleaching earth for a specific residence time, the mixture is finally pumped into leaf filters with stainless steel mesh elements followed by polishing filtration. Deodorizing is the final stage in oil refining in order to remove odoriferous material, free fatty acids and other undesired minor components by steam distillation under condition of high temperature and vacuum to produce a bland oil with a good shelf life.The purpose of degumming is to remove impurities such as phospholipids, gums and proteins etc. There are several methods as follows: water degumming, acid degumming, special degumming etc.

1) Machines include:
degumming pot, deacidification pot, bleaching tower, deodorization pot, steam
separator, gear pump, water pump, etc.
2) Process flow:
First step :
Peanut →clean→Dehusking→crack(or rough milling)→softening→flaking→cooking→pressing→crude Oil

Second Step:

Crude Oil→filtering→ Degumming→ Deacidification→ Water Washing→ Drying→ Bleaching/Decoloring
→ Filtration→ Deodorization→ Packing
