Press preparation corn germ oil process, equipment and operating techniques and other oil preparation process oils much the same process is as follows:
Corn germ, pretreatment, heat treatment, rolling slab, steaming and roasting, crushing, crude oil
Press preparation corn germ oil process – pretreatment: Enter the workshop corn germ oil requirements impurity containing starch and corn bran as little as possible, otherwise it will affect the oil yield. The biggest factor affecting the oil yield is endosperm, the main component of endosperm starch. If the separation is not clean, the starch, the starch itself, which not only reduces the yield, but also because the starch entrained in the germ in the steaming process is easy fried paste, and reduces the pressing out of oil in the oil flowing out of the area, blocking the passage , Furthermore starch itself will absorb some of the grease.

Regulating water: Because corn germ in the crushing process needs to absorb some of the moisture before billets will also be required if the water is too high drying. Adjusting the moisture, lowers the toughness, moisture content is generally below 12% is preferable billets.
Press preparation corn germ oil process - steaming fried: fried steamed for the purpose of damage the cell wall, so that protein denaturation and fully solidified at the same time to reduce the viscosity of the oil, and the oil droplets further agglomeration conducive grease flows out from the cells. After steaming and roasting the material temperature before entering the press and strive to achieve 100
.
Press preparation corn germ oil process – crush : using a continuous screw press. To obtain a high oil yield, while ensuring to meet the above conditions, you must also ensure that the pressure presses in 6.9 × 107Pa or more.
