Soybean oil refining line

RFQ Details

I am giving below the idea of simple and normal refining process for your perusal. Crude oil is normally and usually processed by means of chemical or alkali refining process. Complete alkali or chemical refining includes three main steps, after de-gumming, first step starts with phosphoric acid condition in a knife mixer to transform water insoluble phosphatides in to hydrophilic compounds. Next oil is mixed with caustic which besides neutralizing free fatty acids, also decomposes pigments, traps phosphorus compounds trace metals, proteins and oxidizing materials. Soap stock including deleterious compound is separated by centrifugal force following a washing step mixing with water and then separating in centrifuges. This oil then goes to the second main step, bleaching, where contact with good quality bleaching earth is enough to adsorb pigments, decompose one half of remaining oxidation products, adsorb all soaps and most of phosphatides. Then bleached oil flows to the third and last step, deodorization, where fatty acid, aldehyde, ketones, hydrocarbons and other unwanted materials are vaporized with stripping steam at high vacuum.. Thus there are vessels, mixer, centrifugal, bleacher, filters and vacuum machines are required as well as many pipes, valves, and fittings are also needed. I look forward to your response.
