Cleaning and Separating:
This process mainly to remove the impurities like iron, sand, and others.
The cleaning method mainly includes screen and magnetic separation.
This process namely soften the oilseeds, adjusting the moisture and temperature to a suitable level.
This process has the same purpose with steaming, aiming to make the oil out easily, the difference is just lower the moisture to 5~7%, too much water content will affect the oil outing.
This is the oil extracting process, the cooked oilseeds will be sent to screw oil press machine through the screw conveyor. After pressing, we can get the crude oil.
