What is the vegetable oil refining process?
Firstly,vegetable oil refers to a variety of edible oil refined pass degumming, decolorization, deodorization and other processing procedures. At present, the main vegetable oils on the market are soybean oil, rapeseed oil, rice bran oil, cottonseed oil, sunflower oil and peanut oil.
Production process of vegetable oil

Pretreatment vegetable oil refining
Usually, when we purchase raw materials. We should check the quality of raw materials to reduce mildew. So this is convenient for subsequent processing and conducive to the improvement of oil quality. Because the oil contains impurities, and the water content is different. Therefore, oil needs to be pretreated during pressing and leaching to ensure the oil yield of raw materials and reduce equipment loss. The pretreatment of vegetable oil can effectively remove impurities in the raw material and destroy the structure of the oil. At the same time, it can also adjust the temperature and moisture of oil, improve the flavor of oil, etc.
vegetable oil pressing process
Second,depending on the oil,we can select pressing processes. On the one hand,the cold pressing process can preserve the special substances in the oil. And hot pressing can greatly improve the flavor and yield of oil. High oil content can be pre-extracted and leached by large tonnage. On the other hand,this can reduce the residual oil in the filter cake and increase the economic benefits of the enterprise.
vegetable oil refining
last,Vegetable oil refining is a key step in vegetable oil production. Through this process, oil conforming to national standards. Such as soybean oil, rapeseed oil. His process is as follows:
Step process: Crude oil → degum → alkali melt → hydration → decolorization → degassing → deodorization → cooling → vegetable oil
Findly,with more than 20 years of production experience in vegetable oil refining, BTMA has manufactured several vegetable oil production lines for domestic and foreign customers. Our company can undertake oil extraction, vegetable oil refining, vegetable oil dewaxing equipment and complete sets of vegetable oil production line delivery projects.
