Edible Oil Refining Machine Process- Decolorization Process Decolorization. Vacuum pump with high vacuum of 700mmHg sends alkali oil to decolorization boiler. Keep stirring until temperature reaches 90 degrees, add decolorant (white clay, or active carbon) after moisture reduces less than 0.1%, and separate white clay from cooking oil by compressing air to oil filtration system to obtain decolorized cooking oil. Edible Oil Refining Machine whole process is as follow: 1. Crude Oil Degumming: In this step gums in crude oil are removed by hydration with the help of phosphoric acid. 2. Neutralization: In this step free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap. 3. Bleaching: During bleaching, unwanted pigments are adsorbed physically and oil will become much clearer. 4. Deodorization: Deodorization is used to remove unacceptable odors by steam distillation, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure. 5. Dewaxing (necessary for cold areas) Established in 1995, Wintone Machinery deals principally in designing, manufacturing and exporting complete oil mill plants, solvent extraction plants and related oil processing equipment. We also provide professional customized edible oil refining machine and a variety of oilseed processing services. http://www.oil-processing.com/PRODUCTS/Oil-Refining-Machine/ Email: [email protected] |
