Available with both physical and chemical refinery technology, we are able to provide customers the most affordable corn germ oil refining machine including design, manufacturing, installation with guaranteed quality and reliable service.
Corn germ /maize oil refining process introduction:
Corn germ oil refining process
Degumming process of corn germ oil refining machine:
Intermittent process preheats crude corn germ oil to 80 ~ 85 ℃. The amount of water in crude oil bases on colloid content, and generally 3-5 times of the gum content, water temperature at 85 ~ 90 ℃ (5 ℃ higher than oil temperature). Finish water adding in 40-60min, along with 60-70r/min stirring, continue stirring 3-5min after adding water, and stand for precipitation 2-4h.
Deacidification process of corn germ oil refining machine:
The crude corn germ oil is pumped to Deacidification from oil mill or storage tank & first it is treated with weak solution of phosphoric acid or other suitable degumming agent for removing gums. Deacidification is used remove the Free Fatty Acids (FFA) by adding caustic soda. Oil is heated up to about 60°C by heating coils and oil is stirred by the stirrer. The chemical reaction between free fatty acid and caustic soda forms the soap stock. This soap stock is allowed to settle down in the neutralizer from where it is collected into the soap pans. The oil is then washed with hot water to remove traces of soap particles and free alkali.

Decolorization process of corn germ oil refining machine:
Degumming of corn germ oil can remove grease in oil pigment to improve oil color, adsorption of aflatoxin and trace metals, phospholipids, other gum and other impurities. It ensures high quality of corn germ oil and improves oil stability.

Deodorization process of corn germ oil refining machine:
Control oil temperature to 250 ~ 270 ℃ when decolorized corn germ oil enters into deodorizer, in direct steam injection, the free fatty acids, ketones, aldehydes and other impurities are removed from the oil, the thermal decolorized action also occurs, and the pigment composition is cleaved distilled from the oil. Deodorized vacuum (absolute pressure) controlled at 266 Pa, the deodorization time is about 2h.

De-waxing process of corn germ oil refining machine:
Dewaxing process is carried out for Corn germ oil,Sunflower oil and Rice Bran Oil as they contain waxes compared to other oil. This wax is removed by the dewaxing process. The oils are subjected to winterization process. The oil is first processed in the crystallizer where it is cooled by chilled water circulation. Low temperature results in the formation of crystals which are removed in the filtration process.
