Rice bran oil physical refining process is one of the processes used by rice bran oil refinery equipment to remove impurities in oil when producing rice bran oil. There are two common refining processes: chemical refining and physical refining. The difference between the two is that chemical refining uses the principle of acid-base neutralization to remove free fatty acids in oil, while physical refining uses the principle of steam distillation to remove strong fatty acids and low-molecular odor substances together.
Rice bran oil is an edible oil that is very easy to go rancid. It needs to be refined in time after production to remove impurities to ensure quality and extend storage time. For rice bran oil with high acid value, choosing rice bran oil physical refining process can reduce refining loss, be more economical and environmentally friendly, have low neutral oil loss during refining, high oil yield, and good stability of finished oil.
The rice bran oil physical refining process uses steam to deacidify rice bran oil. The amount of steam used in the deacidification process is closely related to the vacuum degree and temperature. Theoretically, the higher the vacuum degree, the less direct steam is used at the same temperature. In actual production, the amount of steam should be adjusted according to the deacidification effect of each layer of the deacidification tower to maintain a dynamic balance between vacuum degree and direct steam, and avoid excessive or insufficient steam use affecting the deacidification effect of oil.
The rice bran oil refining process flow and the quality of rice bran oil refining machine are one of the factors affecting the refining effect and the oil yield of the finished production. In the purchase of rice bran oil refining equipment, choosing a reliable equipment manufacturer can avoid many problems. When purchasing rice bran oil refinery equipment, it is recommended to visit Huatai Oil Machinery.
