Cottonseed is the seed of cotton. Because it contains about 14-25% oil, it is an important raw material for oil production industry. It and soybean, rapeseed, peanut, sesame and other collectively known as bulk oil. The main cotton-producing areas in China are Hebei, Shandong, Henan, Shaanxi and Shanxi provinces in the Yellow River Basin. The second is Jiangsu, Anhui, Jiangxi, Hubei, Hunan, Sichuan and Zhejiang provinces in the Yangtze River Basin. With the reform and opening up and the restructuring of agricultural products, cotton-producing areas in Xinjiang have developed greatly in the past two decades and are becoming our country important cotton-producing areas.

Cottonseed contains gossypol, which needs to be steamed with high moisture content in the pretreatment process to reduce gossypol content in crude oil. The refined cottonseed oil is completely edible and safe. Improve the quality of wool cotton oil. However, gossypol in cottonseed meal, crude oil and meal prepared by traditional oil-making methods contain gossypol, which affects the feeding value of the meal. Cakes need to be detoxified before they can be used as feed. So far, there is no ideal detoxification process.

Cottonseed contains 39-52% hull and 48-61% kernels. The oil content in the shell is 0.3-1%. Cottonseed contains 30-35% oil and 35-38% protein. Cottonseed contains 0.8-1.3% gossypol. The traditional cottonseed oil-making process is pre-press leaching or pressing. Because cottonseed has high shell content and gossypol, it is necessary to peel and stir-fry cottonseed with high moisture content in the pretreatment process to reduce gossypol content in wool cotton oil.

The cottonseed oil production process has also been used for mixed solvent extraction, that is, using the solubility of gossypol in alcoholic solvents, using mixed solvents (such as hexane, ethanol or acetone, water) to extract cottonseed oil and gossypol from cottonseed kernels at the same time, in order to obtain feed cottonseed meal with Low Gossypol content. However, there are some problems in industrial production, such as difficulty in solvent separation and recovery, high solvent consumption and high cost, and the wool cotton oil extracted by mixed solvent contains a lot of gossypol and pigments, which make the quality of oil decline. This has affected the popularization and application of this technology in industry.

In the rolling process, it is required that the thickness of the blank after embryo rolling should not exceed 0.5mm, the blank is firm, the powder is small, the embryo must also be dried, and then cold pressed by the press to form it. After pretreatment and cold pressing, the material is transported to the leaching workshop. First, the oil is extracted by hexane in the first leacher, then it is leached by methanol in the second leacher to remove phenol without any desolvation treatment. The wet meal after twice leaching has a high solubility, so it must be treated twice. For the first time, special equipment was used for mechanical desolution, and for the second time, special drying equipment was used for steam heating desolution. Hongri grease machinery, environmental protection and energy saving, high oil yield, equipment quality assurance, trustworthy!But with crushing, it becomes the finished cottonseed meal.
