Cottonseed oil refined oil refining process and quality standard of the equipment:
1. Refined oil refining process equipment
Cottonseed hair smoke after caustic alkali refining, can remove free fatty acids, phospholipids, and part of the hair oil pigments, cotton and wool oil contains the gaa toxins and other impurities.Under the condition of vacuum, heating dehydration processing, make the moisture below 0.02%;Then vacuum steam distillation of desolventizing, cottonseed oil amount of solvent refined oil products under 50 x10-6.
2. Cottonseed senior cooking oil and cottonseed oil refining process
In cottonseed oil refined oil for discoloration or other deep processing before, need to use rice bran oil refining equipment (http://www.ricebranoilplant.com/) to remove the free fatty acids, phospholipids, gaa and trace metals and other impurities, otherwise it will be to smoke an adverse effect on decolorization, deodorization and hydrogenation processing, affect the quality of the product.Experience has shown that with a strong caustic alkali refining cotton oil acid, can make the color of cotton oil obviously becomes shallow.
Processing cotton seed oil, should be performed after the adsorption decolorization winterization degreasing, with refined oil equipment removal of cottonseed oil refined oil amount 20% - 20% of the solid lipid composition.Isolated from the solid fat can be used as frying oil, and other processing.Cottonseed oil refined oil cooled after deodorization. Should add oil accounts for the 0. 005% - o. 01% citric acid to the oil, to extend the shelf life of cottonseed oil refined oil.Cotton seed oil plant (http://www.cottonseedmill.com) refined oil frying stability is better, and its flavor is better also Fried products .So. Cottonseed oil refined oil is usually made with rapeseed oil, soybean oil, blend oil, used for cooking, it is very appropriate.
Three, oil factory house cottonseed oil refined oil quality, and the most standard
