Soybean Oil Refining Machine covers entire processing line from crude soybean oil washing and degumming, alkali refining, mixed proportion, decolorization, leaching, physical deacidification and deodorization, crystallization and maturing system, blenching clay quantitative system, freezing filtration and fatty acid recovery system. During all processing of soybean oil refining machine, electrical control system is used in order to make sure the highest quality soybean oil production. The soybean oil after oil refinery process allows edible soybean oil with high purity, high oil yield, low residual oil and low environmental pollutions.

Process of 10T/D Soybean Oil Refining Machine
1. Degumming
Degumming process use hot water to hydrate phosphatides and get them removed. The oil then go through heating, drying and cooling. Before degumming, a plate oil filter is utilized to reduce the content of mechanical impurities, and further avoid emulsification or too much neutral oil contained in foots. The hydrated oil foots can be dried for lecithin, which is used for food additives and feed additives.
2. Neutralizing
The purpose of neutralizing is to remove free fatty acids (FFAs). Accompanied with continuous stiring, caustic solution (NaOH) are pumped into the degummed oil to react with free fatty acids and form soapstocks, which settle down and are pumped into the soapstocks tank for recycling. The oil is pumped into water tank and washed by hot water for 2-3 times till the waste water is clean, then dried and cooled. The byproduct soapstock can be used for manufacture of soaps and biodiesel, added in livestock feed, or treated for the fatty acids it contains.
3. Bleaching
Bleaching process use bleaching earth to remove pigments in oil. Degummed and neutralized oil are pumped into this system, preheated and then mixed in the bleaching tank under vacuum state with
