Rice bran oil is an oil extracted from rice bran, a byproduct of rice processing mill. It is a nutritious and healthy edible oil. Rice bran oil can be produced by pressing or extraction. Because its crude oil contains various active enzymes and impurities, the rice bran raw material and the extracted crude oil will soon acidify. Therefore, it is necessary to treat the raw materials and crude oil in time to ensure their quality.
The oil content of rice bran is low, and the 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 in the extracted cake to less than 1%. The production efficiency is high and the oil yield is high. Therefore, the large rice bran oil mills usually choose the rice bran oil extraction machine 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.
Rice bran pretreatment is a general term for a series of processes such as screening, impurity removal, steaming, and expansion. Its purpose is to change the original morphological structure of rice bran, rice bran extruder 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 miscella. 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 rice bran oil refining, which is also a post-process of rice bran oil processing. 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 refining machine manufacturer is good?
There are many manufacturers of rice bran oil refining equipment on the market, and the quality and price are also different. The manufacturer recommends Henan Huatai Oil Machinery, which independently develops and designs rice bran oil production equipment, provides free scheme design, and provides professional team installation and commissioning technical training on-site, providing professional technical services for oil mills.
