Cotton Seed Oil Press Pressing Method Steps
Cottonseed oil contains a lot of fatty acids needed by the human body. It should be mixed with animal fat. Because cottonseed oil has a lot of linoleic acid, it can effectively inhibit the rise of cholesterol in the blood and maintain the health of the human body. The absorption rate of human body to cotton oil is 98%. Like other edible oils, cottonseed oil is a fatty acid glyceride. Compared with the edible vegetable oil-soybean oil, the structure and composition of the fatty acid have the advantages of cottonseed oil: high content of unsaturated fatty acids such as oleic acid and linoleic acid, accounting for about 78%, and the content of vitamin E is also quite high.
Method of pressing cotton seed oil press:
1. Stir-fried seeds: Generally put 1/4 to 1/3 of the capacity in the pot, stir-fry evenly, diligently turn over, firepower can not be too large, so as not to shell the coke. After the frying, the cottonseed is flattened in the trough, and the barrel is used to dissipate the hot steam. After cooling, it is easy to be screened and cleaned.
2. Screening: Use artificial sieve or fixed sieve to remove dirt and impurities.
3. Grinding and grinding: When grinding, the material should be less, and the flow should be uniform and continuous, and the speed of the grinding is appropriate, so that the cottonseed is easy to be broken.
4. The requirement of adding water when processing the cottonseed oil press: sprinkle water with the roller ring groove. When grinding, while sprinkling water, turn over the seeds, make the billet uniform, and grind the same, about 20 minutes, until the fine blank is not finished. group.
5. Steaming billet: The powder billet should be poured into the steaming barrel to be flattened by hand, so that the steaming barrel is evenly ventilated, and the billet temperature and moisture are consistent. The bottom of the steaming barrel is round like a dovetail shape, and the heat is evenly distributed. The water level of the steamer is kept the same. The distance between the bottom of the steaming barrel and the water surface is more than 16 cm, and the fire should be uniform.
6. Package cake: The package should be mastered to disperse the package. To be fast, it should be packed tightly, and the upper squeeze should be concentrated and fast. Single-turn pizza, about 2 cm thick after pressing, should be as short as possible to prevent the loss of heat in the billet.
7. Pressing: When using the oil press, the cake is aligned and the distance between the circle and the circle is adjusted to prevent the cake from being uneven. When sharpening, it is not until the oil flow is not in the line. When the oil line is broken, it can be squeezed for 2 hours.
8. Clarification and filtration of the oil by the cottonseed oil press: There is a lot of impurities in the pressed oil. It should be cooled quickly, allowed to stand for a while and then filtered to avoid darkening and increase refining loss.
