If your production capacity is large, we recommend groundnut oil press production line for you. If you have limited funds, you can just buy the key machines such as cooking machine, groundnut oil press machine, crude groundnut oil filter machine. If you have enough funds, you'd better buy the whole groundnut oil press production line. Do like this , you can get more crude groundnut oil and the pressed groundnut cake is better.

The second groundnut oil extraction method is pre-pressing and solvent extraction method.

Groundnut oil pre-pressing process is the same with the whole peanut oil press production line. The only difference is that the groundnut oil press production line need to be worked with groundnut oil solvent extraction plant. Groundnut oil pre-pressing machine can extract most of groundnut oil, the groundnut oil solvent extraction plant can recover almost all the oils and leaves behind only 0.7% to 1% residual oil in the raw material. In the case of mechanical pressing the residual oil left in the oil cake may be anywhere from 6% to 14%.
