The crude cottonseed oil obtained either from expellers or solvent extraction plant contains some impurities such as phospholipids, FFA, pigment, odor, etc.Which is bad for our health,so must removed.Cottonseed oil refinery plant is a process to remove these impurities . Cottonseed oil refinery plant 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 20 kinds of oil, such as soybean, rape seeds, peanut, etc. in a small production line or in large oil plant.

We are professional manufacturer of cottonseed oil refining line,we can supply 1-20T/D batch cottonseed oil refining line,30-50T/D semi continuous cottonseed oil refining line and 50-600T/D continuous cottonseed oil refining line .Now, we mainly introduces the batch edible oil refining line.

Main process of soybean oil refining machine/soybean oil refining process:
1. Crude edible soybean oil degumming process,
2. Crude edible soybean oil deacidification/neutralization process
3. Crude edible soybean oil decoloring process
4. Crude edible soybean oil deodorization/distillation (deodorising unit) process
5. Crude palm/rice bran/corn/palm oil dewaxing(fractionation) process

Main Steps of cottonseed oil refinery plant:
1. Crude Oil Degumming Process: In this step gums in crude oil are removed by hydration with the help of phosphoric acid.
2. Neutralization: In this step free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap.
3. Bleaching: During bleaching, unwanted pigments are adsorbed physically and oil will become much clearer.
4. Deodorization: Deodorization is used to remove unacceptable odors by steam distillation, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure.
5. Dewaxing (necessary for cold areas)
Some kinds of oil like sunflower, maize germ or corn oil have waxes inside, if these impurities are not removed, the oil will freeze easily under low temperature, thus effecting oil quality and appearance. so this process is necessary in extremely cold areas.
