2.Pretreatment process of automatic oil extracting machine:

a. Cleaning device:  To remove various impurities in oilseeds, such as: iron, stones, clump, such as the plant leaf, clean up till impurity content does not exceed 0.2%.

b. Crushing machine:  Oilseeds are crushed into 6-8 pieces. In order to meet the requirements of crushing, the peanut is suitable for crushing with the moisture of 7% to 12%.

c. Softening Process:  The purpose of softening is to adjust the moisture and temperature of oil, and make it soft.

d. Flaking process:  Rolling raw material into flakes, and the purpose is to increase surface area, destroy the peanut cell tissue, shorten the way of oil out from cake.

e: Cooking process:  Use steam cooking, inject direct steam and cook the flakes to meet the requirement of oil press.

f. Pre-press:  Press the flakes to leave about 16%-18% in the cake. The cake will go to extraction process.

g. Second oil press: Press the cake till the oil residue is about 5%.
