Henan Hengyi Heavy Industry Equipment Co., Ltd. specialized in edible oil pressing,soybean crude cooking oil refining plantne,oil refining equipment more than 11 years, during the processing of edible oil crushing, refining practice, we summed up a set of effective and less investment, quick, easy to operate edible oil refining method.

Refining the crude oil by degumming (dephosphorization), deacidification reach the edible standards, widely welcomed by the small oil factory.

Features of crude cooking oil refining plant
Our crude oil refinery machine provides professional oil refinery processes, including degumming, dehydration, deacidification, decolorization, bleaching, deodorization, and dewaxing. The complete set of mustard crude cooking oil refining plantnery adopts the most advanced physical refining or chemical refining technology on basis of oil property to get the purest edible oil at the lowest cost investment and energy consumption.

Introduction of four sections in small scale crude cooking oil refining plantry :

1.Degumming Section: Some impurity, such as Phospholipid, gum, and protein, can be dissolved  into oil when there is no water, but once there is water in oil, these impurity can be dissolved into water. So, in degumming section, we use the hot water to wash crude oil for two-three times to remove these impurity.

2.Neutralizing Section: Crude oil contains much free fatty acid, which is harmful for health. Free fatty acid can have the reaction with caustic soda, during the reaction, it can be saponified and becomes soapstock, then small soapstock pellets will sink and  becomes sediment and be pumped out. After neutralizing, most of the free fatty acid will be removed out.

 3.Decoloriztion Section: Most of the crude oil has deep color because of the pigments, such as carotene, xanthophyll, etc. We use bleaching earth to remove pigments, because bleaching earth has strong adsorption capacity. Then pump oil into plate filter to  remove bleaching earth, then pigment also will be removed out along with bleaching earth, then oil will be clean and transparent.

4.Deodorizing Section: Pure oil has no smell, but different crude oil has their special smell because of some volatile matters, for example the oxide for ketones, aldehydes, hydrocarbons. In deodorizing section, we deliver steam into oil continuously, and make  sure steam and oil can fully contacted under high temperature and pressure, then volatile matters can be removed out along with the steam.
