Groundnut Oil Extraction Machine, Capacity : 5-2000 tons per day

The whole groundnut oil extraction machine contains three workshops: groundnut pretreatment and prepressing workshop, groundnut oil extraction workshop and groundnut oil refining workshop.

3. Craft flow of refining workshop of groundnut oil extraction machine
Crude groundnut oil--degumming and deacidification-- decolorization--deodorization--refined groundnut oil.
Main Process:
1. Degumming and deacidification: The gumming is moved by phosphoric acid and hot water. There are two ways to move the acid in the groundnut oil. One is chemical way, the other one is physical way. The chemical way is using NaOH to react with acid. This way is suitable for the capacity of 5-30T per day. The physical way is using steam and centrifugal to move the acid. This way is used for capacity from 30-2000T per day.
2. Decolorization: This step is used to adjust the color of the oil. You can control the color of the peanut oil according to the requirement of your market.
3. Deodorization: The function of this step is to move the special smell in the oil. This is an important standard for refined groundnut oil. Because of the good smell of groundnut oil, you can choose this step according to your market.
