Peanut oil, also known as groundnut oil, is a kind of vegetable oil that is obtained from peanuts/groundnuts. It has a strong flavor and is in bright color. The composition of peanut oil is great for the absorption of human body. Using peanut oil as a common cooking oil can help prevent skin wrinkling and aging, protect blood vessel walls and is conducive to arteriosclerosis and coronary heart diseases.

The typical process for peanut oil making are peanuts shelling, peanut selection and cleaning, peanut roasting, peanut oil pressing and peanut oil filtration and peanut oil refining.

Peanut Oil Preparatory and Pressing Sections

1. 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.

2. Peanuts 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.

3. Peanut Kernels 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.

4. Pressing Here we adopts screw oil press which is widely used in small sized oil plant. Simple operation and high pressure ensures continuous processing.
