Rice bran oil can be produced by pressing or extraction. Because crude rice bran oil contains various active enzymes and impurities, the rice bran raw materials and the extracted crude oil will soon acidify. Therefore, it is necessary to treat the raw materials and crude rice bran oil in time to ensure their quality.
The oil content of rice bran is low, and the extraction efficiency of the rice bran oil pressing process is low and the output is small. The rice bran oil extraction process can well extract the oil from the rice bran, and control the residual oil content in the extracted cake to less than 1%. The production efficiency is high and the oil yield is high. Therefore, rice bran oil mills with large output usually choose the rice bran oil extraction equipment and extraction process to produce rice bran oil.
The rice bran oil extraction production line can be divided into four parts: rice bran pretreatment, rice bran oil extraction, crude rice bran oil refining, and oil filling.
Pretreatment is a general term for a series of processes such as screening, impurity removal, conditioning, and expansion of rice bran. Its purpose is to change the original morphological structure of rice bran. Expansion can destroy the original cell structure of rice bran, reduce the powder degree of raw materials, have more porosity inside, improve its permeability during the rice bran oil extraction process, and shorten the extraction time.
During extraction, the solvent and rice bran cake are first contacted by spraying or soaking. The principle of mutual dissolution of solvent and oil is used to dissolve rice bran oil in the solvent to form a mixed oil. Then, the difference in boiling points between oil and solvent is used to evaporate and strip, so that the solvent is vaporized and separated from the oil, thereby obtaining crude rice bran oil.
Then refining, which is also an important process of rice bran oil processing in rice bran oil production. By deacidifying, degumming, deodorizing, decolorizing, dewaxing and other processes, the free fatty acids, colloid-soluble impurities, pigments, waxes, etc. in the crude rice bran oil are separated from the oil. After passing the batch inspection, the edible finished rice bran oil that meets the edible oil standards is obtained, and then it is filled and sealed through the rice bran oil filling production line for sale.
Which rice bran oil machine manufacturer is good?
There are many manufacturers of rice bran oil processing machine on the market, and the quality and price are also different. The manufacturer recommends Henan Huatai Cereals and Oils Machinery Co., Ltd., with a factory building of 100,000 square meters, independent research and development design and production equipment, free scheme design, professional team on-site installation and commissioning technical training, and professional technical services for rice bran oil mills.
