mature technology cold screw oil press machine with ISO&CE 0086-13419864331

(1). Clean oilseeds

Fist step of pretreatment, also is the fist step of making edible oil. By using Wind-driven separator, dust removing system, magnetic separation, gravity separator to remove impurity.

(2). Shelling, debarking,delint,soften

Second step of pretreatment, by using shucking machine to remove shell of oil seeds, because shell will reduce the rate of oil yield and life of the production line. Some of the oilseeds need to be softened like soybean or other hard oil plants.

(3). Break oil crops

Third step of pretreatment, by using flaking machine to roll oilseeds into base. About 4 valve. Like Soybean 2-4valve, peanut 4-6valve. Thickness of the base is about 0.1-0.5mm. This will make the surface of oilseeds bigger, easy to be cooked. extract edible from oilseeds easier, and can also rise the oil yield.

(4). Cooking oil seeds

Forth step of pretreatment, by using cooker make green billet to be cooked billet. Make the oil fused on the surface of the oil seeds. It will make edible oil easier to be prepressed extracted from the oilseeds.

(5).Prepress/press oil seeds

Fifth step of pretreatment, by using oil crops press machine press some of the edible oil from oil seeds. And make oil seeds become cake. After this step you will get crude edible oil and cake. After prepressing, there are about 18% resid in the cakes, the cakes will be sent to the solvent extraction plant, by the process of solvent extraction plant, we can get the oil in the cakes. And the resid in the cake will less than 0.8%.
