Brief Introduction of Cotton Seeds Oil Refinery Plants
Oil Refining is a progress of removing the impurities such as phospholipids, FFA, pigment, off-flavor in cruel oil before edible application. Oil refining machine is used for producing the first or second-grade edible oil. We are able to supply the professional oil refining plant and related oil refining equipment. With the high degree of automation, the oil refining machinery can refine 20 kinds of oil, such as soybean, rape seeds, peanut, etc. in a small production line or in large oil plant.
The Process of Cotton Seeds Oil Refinery Plants
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 into cakes or meals in the extraction workshop. Hydration degumming process can improve oil edibility, storage and do well to downstream neutralization section.
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.
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.
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 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 acid which is essential to the human body, better to mix animal fats to use. Yet, if people eat crude cottonseed oil, it will cause damage spermatogenic cells, 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. Refined clear cottonseed oil without gossypol and other toxic substance can be used as cooking food. Due to clear cottonseed oil contains a large quantity of linoleic acid, it can prevent the content of cholesterol rising, maintain human body health. Human body consumption of cottonseed oil is up to 98%.
Cottonseed Oil Needs Refining
It is said that refining process can reduce toxicity. Cottonseed oil is one of main cooking oil. But crude cottonseed oil contains gossypol (approximate 1%), colloid and waxiness (content vary with shell content), and the quality is poor. It’s not better to eat it directly. The refining process technology is also complex.
