Small scale crude oil refinery, oil refinery plant small scale crude oil refinery. The removal of stearin is the important part of oil refinery for sunflower oil, rice bean oil and corn oil. I will introdue some information about stearin removing at the following part.
Compared with general vegetable oils such as rapeseed oil, soybean oil, peanut oil and others, crude rice bran oil is not only with high acid value and deep color, but also contains 2% to 7% wax. Wax of rice bran oil is called "bran wax." It and Its component is different from that of mineral waxes (ie paraffin) , the later is long-chain alkanes, and the main ingredient of rice bran wax is esters formed by higher fatty acids and higher fatty alcohols.
At higher temperatures, bran wax molecules are dissolved in oil as dispersion state. Because of its high melting point, when the temperature is gradually lowered, it will be crystallized and separated from oil phase, which makes oil the opaque so that affect the appearance of the grease. At the same time, high wax content of rice bran oil feels paste mouth when eating it, affecting appetite, it can not be absorbed and digested by the human body, it is necessary to be removed. Also need "dewaxing" when it used corn oil to produce salad oil. The process of wax removal is referred to as "dewaxing."
Rice bran oil after degumming, deacidification, bleaching, deodorization and dewaxing, already can be eaten, but with different purposes, the requirements by people for oil is also different. Example, salad oil, which requires that it does not contain solid fat (referred to as STEARIN), in order to maintain transparency in the 0 ℃ (ice-water mixture) within 5.5 hours. Rice bran oil through the five process, still contains part of the solid fat, cannot reach the quality standards of salad oil, if you want to get rice salad oil, the solid fat must be removed. This process for removing solid fat of oil is called STEARIN REMOVING of oil, the method is carried out WINTERIZATION. It also needs STEARIN MOVING when you use palm oil, peanut oil or cottonseed oil to produce salad oil.
