Processing peanut oil is a good project, but the crude oil extracted by pressing and extraction process cannot meet the edible oil standard. It needs to be refined by peanut oil refining machine to meet the national standard requirements and put on the market.
Peanut oil needs to go through degumming, deacidification, dehydration, decolorization, deodorization, dewaxing and other processes during the refining process. What are the main functions of these processes? Huatai Oil Machinery will give you a brief introduction.
Degumming: Degumming is also called dephosphorization, which is to remove phospholipids, mucus, resin, protein, sugar, trace metals, etc. in crude oil. Generally, hydration, acid refining or enzyme degumming is used.
Deacidification: Generally, the neutralization method of edible grade alkali solution can remove FFA, acid pigments, sulfides, oil-insoluble impurities and trace metals in the oil.
Washing: Wash away the soap and water-soluble impurities remaining in the alkali-refined oil.
Dehydration: Use heating and vacuum drying to remove water from refined oil.
Decolorization: Use adsorbents such as activated clay, aluminum silicate, activated carbon, etc. to remove various pigments, colloids, oxides, etc. in the oil.
Deodorization or physical refining: Use the vacuum stripping principle to remove low molecular odor substances, FFA, monoglycerides, diglycerides, sulfides, and pigment thermal decomposition products in the oil; the purpose of physical refining is mainly to remove FFA.
Dewaxing or degreasing: Mainly use freezing, crystallization or winterization crystallization, fractionation to remove wax or solid fat in the oil.
Peanut oil refined through the above-mentioned processes, and then use appropriate filtering equipment to remove solid particles in the oil, clay in the bleached oil, and catalysts in the hydrogenated oil, etc., and then fill and seal, and it can be sold smoothly on the market.
