Peanut Oil Pressing Sections
Cleaning and Drying
There are impurities in peanuts before its processing. The residues include mud, stem or leaves, without cleaning, they will influence peanut oil and oil cakes quality, at the same time, they will absorb some fat and reduces oil rate. If there are some sand or metal, there maybe accident in the future processing.
There are many methods to clean them and it depends. If the impurities are light in weight like grass, stem and leaf, we can choose wind, using air stream to blow them away. If the residues are small in size, we can select them by screen. To the metal material like steel, we choose electromagnet or permanent magnet to separate them.
Shelling
Shelling is to reduce shells absorption to fat and improve oil rate; increase the processing capacity and lower the wearout of press machine; process good quality oil cakes and make them widely used.
Cooking
Cooking is one of the important processing steps in oil extraction. We should add 8-10% water before cooking. Peanut after cooked called ripe billet, and the pressing process is called hot press. Peanuts are mainly hot press. The cooking process influences directly on the smooth press, oil rate and oil cake quality. When the moisture content is close to 1-2% and the temperature reaches 120-130, peanut is suitable to finish cooking and begin to press.
Pressing
Here we adopts screw oil press which is widely used in small sized oil plant. Simple operation and high pressure ensures continuous processing.
