Cotton Seeds Oil Refinery Plant Overview
Cotton Seeds Oil Refining is the progress of removing impurities such as phospholipids, FFA, pigment, and off-flavor in cruel oil before edible application. Oil refining equipment is used for producing first or second-grade edible oil. We can supply the professional cotton seeds oil refining plant and related oil refining equipment. With a high degree of automation, the edible oil refining plant can refine over 20 kinds of oil, such as soybean, rape seeds, peanut, etc. in a small oil production line or a large oil mill plant.

Degumming
This progress adopts hydration by adding hot water to remove the agglomerated and deposited hydrosol and phosphatide because of their water affinity. The separated gum (after being dried) can be made into lecithin or added to cakes or meals in the extraction workshop. The hydration degumming process can improve oil edibility, and storage and do well to the downstream neutralization section.
Neutralizing
Oil containing fatty acid is mixed mechanically with a slight excess of alkali to react with fatty acids present to form soaps. The mixture is centrifuged to separate oil from soapstock. After washing with water, the water is separated from the oil in a second centrifuge.
Bleaching
Degummed and neutralized oil are pumped into this system and mixed with by the use of bleaching earth, a special soap, gum, and pigment-attracting adsorbent. The mixture enters the Pre-filtration Dryer where the moisture in the oil and adsorbent is evaporated. Then the oil is pumped through an automatically closed filter to remove clay.
Deodorization
The oil contains the disagreeable flavor and odors that are naturally present or created during processing. All odoriferous matter is distilled off by injecting high-pressure steam through the vacuum system. Then the product achieves the national standard.
What is Cottonseed Oil?

Cottonseed oil is classified as a vegetable oil. It is extracted from the cotton plant or, more accurately, from the seeds and is generally used for cooking. Seed oils are preferred for diets that require lowered intakes of saturated fats. This makes cottonseed a kind of good oil for preparing healthier foods.
Cottonseed oil contains pressing cottonseed oil, solvent extraction cottonseed oil, genetically modified organism cottonseed oil, crude cottonseed oil, and the finished product of cottonseed oil. Its color is deep redder than other oils, can be used as cooking oil after refining, as well as contains a large sum of fatty acids that are essential to the human body, It is better to mix animal fats. Yet, if people eat crude cottonseed oil, it will cause damage to spermatogenic cells, and lead to aspermia and sterility.
Composition and Content of Cottonseed Oil
Refined cottonseed oil usually is pale yellow or dark red. Its fatty acid generally includes 21.6-24.8% palmitic acid, 1.9-2.4% stearic acid, 0.1% arachidic acid, 18.0-30.7% oleic acid, and 44.9-55.0% linoleic acid. Clear cottonseed oil without gossypol and other toxic substances can be used as cooking food. Clear cottonseed oil contains a large quantity of linoleic acid, it can prevent the content of cholesterol from rising, and maintain human body health. Human body consumption of cottonseed oil is up to 98%.
Cottonseed Oil Needs Refining
It is said that the refining process can reduce toxicity. Cottonseed oil is one of the main cooking oils. But crude cottonseed oil contains gossypol (approximately 1%), colloid, and waxiness (content varies with shell content), and the quality is poor. It’s not better to eat it directly. The refining process technology is also complex.
