cotton oil production line
Preconditioning station based processing steps: cleaning, conditioning, broken, softening, rolling embryo, steaming and roasting and pre-press. Wherein the pretreatment of cottonseed to have lint, peel and other technology. Pretreatment Section of oil processing equipment is the most important part, but with different pre-processing machinery and equipment, and the different requirements of different end-oil production of raw materials and have different configurations and processes. Division I for different fuel pretreatment plant and process configuration is not the same, for example, the need for expanded rice bran pretreatment steps, the need for pre-processing of palm fruits to kill the yeast section, cottonseed pretreatment need to have lint process Wait.
Shenzhou grease mechanical pretreatment equipment advantages:
1, to reduce wear and tear on the follow-up equipment, improve environmental quality workshop;
2, improve equipment production, improve oil yield, to ensure maximum quality fat, meal and byproducts;
3, the lowest rate of fuel crushing, destructive for protein meals minimum.
Pretreatment Applicable oil: soybean, rice bran, sunflower, rapeseed, cottonseed, walnuts, corn germ, peanuts, copra, castor bean, palm kernel, palm nuts, sesame, olive, algae oil and the like.
Pretreatment capacity: 30-5000T / Day

Cleaning is to remove the various impurities in the cottonseeds by cottonseed cleaning equipment. Cleaning cottonseeds can reduce oil loss, increase oil yield, and increase the quality of oil, cake, and by-products. reduce the abrasion of equipment, increase the handling capacity, and improve the work environment.
The cottonseed hulls contain brown pigment. pesticide residue, wax, and lint. Hulling cottonseeds can increase the handling capacity of the oil press and increase oil yield, improving the quality of crude oil and meal. Cottonseed hulls can be used for cultivating mushrooms and used as livestock feed, etc.
The flaking process makes the cottonseeds into flakes and destroys the cell walls, which can largely shorten the oil path to increase the oil-yielding speed and oil yield. Cottonseed oil processing plant adopts hydraulic flaking rollers which can guarantee the uniform thickness of the cottonseed flakes.
Cottonseed oil processing plant adopts vertical cookers for the cooking process. The flakes from the flaking roller enter the vertical cooker. By high temperature and high moisture cooking, the temperature and moisture of cottonseed flakes are adjusted, the free gossypol content of the crude oil is reduced and the quality of the crude oil is improved.
Oil pressing is to press the cottonseed kernel into thin slices to increase the surface area of the oil, destroy its cell structure, shorten the oil path, and speed up the oil output. The pressing efficiency of the oil press and the stability of the equipment are the keys to the oil pressing process. The oil press produced by our company has the characteristics of large output, low cake residue, and high cake quality.
After pretreatment and cold pressing, the material is transported to the extraction workshop. Oil extraction is using the organic solvent to extract oil from the pre-pressed cake inside the oil extractor. Multiple oil extractors such as loop type, rotocel, and towline extractors can be used for the cottonseed oil extraction plant. After oil extraction, miscella and the solvent containing wet meal are obtained. The miscella is pumped into the hydrocyclone to remove the fines and then the miscella enters the miscella tank in the cottonseed oil extraction plant.
The colloidal impurities in crude oil are mainly phosphorus. The presence of colloids such as phospholipids not only reduces the quality of oil but also promotes transitional emulsification between oil and alkali in the alkali refining deacidification process, increasing the difficulty of separation of saponins and aggravating the loss of neutral oil. Therefore it should be removed first.
Oil deacidification mainly removes free fatty acids in crude oil, as well as a small amount of colloids, pigments, and trace metal substances in the oil.
The color of the oil and some other impurities must be decolorized to meet product quality standards. At the same time, it provides more favorable conditions for deodorization and refining. Decolorization must meet the final required color index of the product.
The purpose of oil deodorization is to remove odor-causing substances and other easily volatile substances in the oil, improve the odor and color of the oil, and improve the stability of the oil.
Cottonseed oil refinery machines are divided into three types: batch type, semi-continuous, and full-continuous. They use different capacity oil refining methods, but the final cottonseed oil is all qualified with the standard.
Cottonseed oil fractionation plants can obtain liquid oil and solid fat by cooling crystallization and solid-liquid separation. The plant has the features of advanced technology, fully automatic, high liquid oil yield, and high solid fat purity. Cottonseed oil contains a fair amount of saturated fatty acid and thus has a high melting point. At low temperatures, part of triacylglycerol crystallizes and precipitates, which restricts the application, transportation, and trade of cottonseed oil. By cottonseed oil fractionation, liquid oil and solid fat are obtained. The liquid oil can be used to make mayonnaise and salad dressing. The solid fat can be used to manufacture frying oil, margarine, shortening, cocoa butter substitutes, etc.
