Rice Bran Solvent Extraction and Oil Refinery Plant

Rice bran is a kind of special oilseeds with quite low oil content, which is especially applicable to getting edible rice bran oil by one time solvent extraction and oil refinery process. Rice bran one time extraction needs to go through rice bran pretreatment and rice bran oil extraction processes. Rice bran pretreatment contains steam flaking, granulation and expansion. There are dry and wet puffing available. Rice bran oil extraction plant goes through a bit different oil extraction method, which pays more attention to rice bran extraction and wet bran desolventization process.

Rice bran oil extraction process obtains a kind of high acid value crude oil. The adoption of physical rice bran oil refining process has obvious advantages in increasing the rate of oil refining and economic aspects. Rice bran oil refinery process includes degumming, blenching, deacidification, dewaxing, degreasing. The key point is distillation deacidification, degumming and deacidification are especially important.
In practical applications, rice bran oil physical refinery is adjustable according to rice bran raw material condition, refined rice bran oil product quality grade, combined with chemical oil refinery to make free adjustment of finished rice bran oil.
The time rice bran oil has lower acid value, sometime rice bran passing through fresh treatment can control acid value of rice bran under 6mgKOH/g. This kind of excellent quality crude rice bran oil can also used chemical oil refining process to get high quality rice bran oil. There is no need to consider physical oil refinery process.

The adjustment of ordinary rice bran oil and high grade rice bran oil can make rice bran achieve high quality rice bran oil refinery condition. The available rice bran oil after physical oil refinery is available in quite low acid value and good oil color. The oil quality can reach first grade rice bran oil. The time users are processing high acid value rice bran oil, will get third or fourth grade rice bran oil.
