Intermittent refining equipment is mainly used in the refining process of large oil plants, with high refining rate and continuous process, which can refine different grades of oil. Including all kinds of vegetable oils: soybean, peanut, cottonseed, rapeseed, jade, etc. Suitable for all oily plants.
 
In the full continuous refining process, Henan Chengli machinery has absorbed advanced technology at home and abroad, combined with many years of practical experience, and adopted a unique degumming process. Under the premise of prolonging the reaction time of phosphoric acid and oil, by adding specific additives to maximize Limit the removal of phospholipids in the oil. The new white clay automatic quantitative system can make oil products more reliable, with less investment in the full vacuum closed refining process and good product quality. According to different oil types and different requirements for products, the best process route can be designed.

Deacidification: It is to remove free fatty acids from crude oil. This is the most critical stage in the whole refining process. There are many methods of deacidification, and the most widely used method is alkali refining, that is, alkali is used to neutralize free fatty acids, so that free fatty acid soap can be separated from oil.
Degumming: Remove the gum (mainly phospholipids) from the crude oil. Degumming technology mainly adopts hydration degumming method, that is, by using the hydrophilicity of gel soluble impurities such as phospholipids, a certain amount of water or electrolyte dilute solution is added to the crude oil under stirring, so that the gum soluble impurities in the crude oil can absorb water, expand, agglomerate and separate.
Decolorization: Adopt adsorption decolorization method to remove pigments, trace soap, phospholipids, polycyclic hydrocarbons and residual pesticides in crude oil.
Deodorization: Deodorization can not only remove the odorous substances in the crude oil, increase the smoke point in the oil, improve the flavor of the oil, but also effectively remove pollution, at the same time it can also remove peroxides and their decomposition products, and remove the protein in the moldy oil Volatile decomposition products can remove residual pesticides such as small molecular weight polycyclic aromatic hydrocarbons to reduce them to a safe level. Crude oil deodorization means that water vapor passes through high-temperature grease containing odorous components under high vacuum, and the odorous components in the gas-liquid surface contact oil volatilize into the water vapor bubble according to the ratio of its partial pressure. Escape together with water vapor to achieve the purpose of deodorization.
Dewaxing: According to the melting point difference between wax and grease and the solubility (or dispersion) of wax in grease decreases with temperature, the crystal wax is precipitated by cooling, and the purpose of dewaxing is achieved by filtration or centrifugal separation. One common point of all dewaxing methods is that the temperature is below 25°C to achieve good dewaxing results.
