Refining is an essential process for the production of oil, because there are still some impurities such as phospholipids, FFA, pigment, odor, etc in the raw oil. As a manufacturer of oil machinery, which is equipment of edible oil for worldwide customers, we can offer professional technical installation for the processing of edible oils. We can provide turnkey for refining oil with a capacity of 1-20 tons/day. Characteristics of the machine refining of edible oils: 1. Wide application: various kinds of oil can be cleaned of our mini oil refining machine, such as peanut oil, sunflower seed oil, soybean oil, coconut oil, palm kernel oil, rapeseed oil, etc. 2. Can be configured possible food refining machine. Completely mini oil refinery machine can work independently or together with whole oil line. The basic processes of refining: 1.The degradation of crude oil: at this stage the resin in the crude oil are removed by hydration with the help of phosphoric acid. 2.Neutralization: at this stage the free fatty acids neytralizuya using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on the soap. 3.Bleaching: the bleaching unwanted pigments are adsorbed physically and oil becomes much clearer. 4.Deodorization: Deodorization is used to remove unacceptable odors by steam distillation, the aromatic compound is separated with the help of live injected steam into heated oil under high vacuum. 5.Dewaxing: Some kinds of oils such as sunflower, maize germ or corn oil have waxes inside, if these impurities are not removed, the oil can easily freeze at low temperature, which leads to the quality and appearance of the oil. therefore, this process is necessary in extremely cold areas. The main part of the periodic machines for refining of edible oil: 1.The decolorization tank: bleach pigments from oil. 2.Deodorizing pot: remove odor from bleached oil. 3.Oil furnace: provide enough heat for the refining sections which require high temperature 280 ℃. 4.Vacuum pump: provide high pressure for bleaching, deodorization which can reach 755 mmHg or more. 5.Air compressor: dry the bleached clay after bleaching. 6. Filter press: filter the clay in the bleached oil. 7. Steam generator: produce steam distillation.
