Cotton Seeds Oil Refinery Plants   
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 equipments. With high degree of automation,the oil refining machinery can refine *0 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 
Degumming
This progress adopts hydration by adding into 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.
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 soap stock. 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 automatic 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 vacuum system. Then the product achieves the national standard.
