Cottonseed oil is the oil obtained by pressing cotton seeds after processes such as delinting, shelling, crushing, steaming and frying.
The traditional cottonseed oil processing is to extract oil by physical pressing. The cottonseed oil press machine is used in industry to press the oil. The advantage of the oil pressing method is that there is no chemical residue in physical extrusion, and the nutrition is better retained, but the residual oil rate of the cake is high. Later, with the introduction of the oil extraction process, technicians combined the two processes of pressing and extraction. First, the cottonseed is pre-pressed to extract oil, and then the pre-pressed cake is crushed and the remaining residual oil is extracted with solvent. It can greatly improve the oil yield and increase the efficiency of the cottonseed oil plant. This process is called pre-pressing-extraction process.
The complete set of cottonseed oil pre-pressing and extraction production line includes pretreatment equipment, pressing equipment, extraction equipment, refining equipment and other main processing equipment. Among them, cottonseed oil refining equipment is an important equipment in the production line to ensure product quality. Cottonseed oil refinery includes degumming, deacidification, dehydration, decolorization, deodorization and other main processes. It can be used for the refining of various oils and fats, and removes gel-soluble impurities, fat-soluble impurities, pigments, odor substances, etc. in oils and fats.
Cottonseed crude oil contains gossypol, which will have adverse effects on the human body when consumed. With the development of society, people have found in modern industrial production that gossypol in cottonseed oil can be removed through oil refining machine to further improve the health and quality of consumption.
The removal of gossypol in cottonseed oil refining equipment is mainly concentrated in the deacidification process. The main purpose of the deacidification process is to remove free fatty acids that affect the quality of oils. In the deacidification process, alkali solution will be used to neutralize free fatty acids. Since gossypol is weakly acidic, it can react with alkali solution to generate gossypol sodium salt that is soluble in water but insoluble in organic solvents. During the alkali refining process, it will be discharged from the oil tank along with soap nuts.
Refining equipment is one of the important equipment for producing edible oil that meets national standards. The quality of the equipment and the refining process are one of the important factors affecting the quality and oil yield of finished oil. Therefore, for oil mills, choosing a set of high-quality equipment can provide a lot of help for oil mills. The selection of equipment manufacturers should be investigated from many aspects such as strength, technology, reputation, and service. Comprehensive comparison and selection of reliable manufacturers for cooperation can provide help for subsequent production of oil mills!
