Refining is an essential process for the complete castor bean oil pressing line because there are still some impurities such as phospholipids, FFA, pigment, odor,etc. in the crude oil. As a prominent oil press machines manufacturer who is devoted to processing pure edible oil for worldwide customers, we can provide professional technical support and manufacture first rate machines for your oil refining.
Craft flow for oil refining workshop:
Crude oil → degumming and deacidification→ decolorization →deodorization→ refined oil.
Castor Oil Refinery Process – Degumming
Hydration Degumming: Hydration degumming mean adding into some hot water and controlling the corresponding conditions to make the hydrosol agglomerated, deposited and then separate them. The separated gum(after being dried) can be made into lecithin or added into cakes or meals in the extraction workshop.
Castor Oil Refining Process – Bleaching
High activity clay is added into oil. Mix and heat mixture of oil and clay to make the small particle of pigment absorbed on the crystal of clay. At last filter the oil. Mechanism, liable performance, well configured equipment. Bleaching Tower and Filters ensures excellent bleaching and separation effect.
Castor Oil Refining Process – Deodorizing
Combined deodorizing is the latest technology, which improves oil flexibility significantly. Detailed deodorizing process in the entire oil refining plant is: Most heat of bleached oil is recovered by Heat Exchangers. The bleached oil is heated to the process temperature by mineral oil or high pressure steam and then the oil enters into the Combined Deodorizer.
