2. Pretreatment process of screw press peanut oil machine

a. Cleaning device:  To remove various impurities in oilseeds.

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.

3.Pressing process of screw press peanut oil machine

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

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

Main Section Introduction of the refining process:

a. Refining section: used to P-acid de-gumming, alkali refining de-acid and water rinsing.

b.Decoloration Section: used to remove off pigments, bleaching oils and grease dehydrate.

c. Deodorization Section: to remove off the odor components in oil.

d. Dewaxing Section: used to remove off the wax in the oil, in order to get the high quality oil.
