Cottonseed contains 14%-25% of oil and the kernels contain 30-40%. By degumming, the filtered cottonseed oil is preheated and phosphoric acid is added to change nonhydratable phospholipids into hydratable phospholipids. Solvent recovery can reduce solvent consumption and ensure safe production. State of the art technology for oil extraction for oil cake of any seed. Lecithin Powder Plant, Castor 2. Hydrogenation Plant, All the processes are seamlessly integrated for smooth operations, Continuous operation for improved productivity and consistent product Generally speaking, cottonseed oil processing mainly including the flowing production process, they are seed cleaning, cracking, flaking, cooking, expelling and refining. The mixture from the bleaching tower is pumped into the leaf filter to remove the waste clay. Cottonseed oil fractionation plant can obtain liquid oil and solid fat by cooling crystallization and solid-liquid separation. 4. The toothed roller crusher in the cottonseed oil mill plant adopts two tooth rollers with different speed to remove the hull. Solvent extraction plant of cotton seed. The oil is then dehydrated under vacuum. During the solvent extraction process, the cottonseed kernels are subjected to fine grinding by pushing them through an expander and then the solvent is used to extract most of the oil. The bleached oil is pumped into the deodorization tower in the cottonseed oil refinery plant to remove the free fatty acids and odor substances so that to improve the flavor, stability, color, and quality of the oil. To reduce the toxicity of gossypol, usually high moisture cooking is adopted in the cottonseed oil plant. Hulling cottonseeds can increase the handling capacity of oil press and increase oil yield, improve the quality of crude oil and meal. For the capacity of more than 20 tons per day, usually, solvent extraction method is adopted with cottonseed oil pre-press used to extract part of the oil. If your cottonseeds are with lint, then you need to add cottonseed delinting machine in the... 2.Cotton Seed Cleaning The pre-pressed cake is sent to the solvent extraction workshop. The liquid oil can be used to make mayonnaise and salad dressing. Cottonseed kernels contain 0.5%-2.5% of gossypol. Send Email, Vegetable The phospholipids absorb water and agglomerate so that do not dissolve in oil, reducing the binding with free gossypol. The hulls and kernels flow out from different outlets of the hull beater. The solvent extraction of pre-pressed cotton seed cake is like normal solvent extraction of any pre-pressed cake. Oil Derivatives Plant, Cotton The solvent-extracted meals have a lower fat content of 0.5% than the mechanically extracted meals with a fat content of 2.0%. Your Enquiry has been sent successfully. The pre-pressed cake has low residual oil rate and is easy for solvent penetration. Industrial oil processing for the edible oil generally involves the solvent extraction step which may or may not be preceded by pressing. At low temperature, part of triacylglycerol crystallized and precipitated, which restricts the application, transportation and trade of cottonseed oil. The miscella in the miscella tank enters the first long tube evaporator, the second long tube evaporator and the disk stripping column to remove the solvent. The wastewater is separated from the oil in a second centrifuge. The leaf filter used for the cottonseed oil processing plant has the features of high precision, easy to discharge the residue. The solvent recycled enters the solvent holding tank for circulation. If your cottonseeds are with lint, then you need to add cottonseed delinting machine in the cottonseed oil plant. The roller has high hardness and stable performance. Phospholipids are easy to adsorb bleaching clay and reduce bleaching effect. quality High production capacity, Material : cotton seeds, soyabean, rice bran, sunflower, cattle feed, Automatic Grade : Automatic, Semi-Automatic. The vent gas in the cottonseed oil extraction plant enters the mineral oil system for further recovery of solvent. The degummed and neutralized oil is mixed with bleaching earth and then the mixture is sent into the bleaching tower in the cottonseed oil refinery plant. After processed by the cottonseed oil refinery plant, the gossypol content in the oil is less than 0.01%.
