Merchants who invest in oil and fat equipment know that the process of oil extraction is divided into three stages, namely the oil pretreatment stage, the oil leaching stage and the oil refining stage, and the oil refining stage is divided into degumming, deacidification, dehydration, decolorization, deodorization, dewaxing and other steps.
Deodorization is an indispensable step in the whole process when using grease machinery to produce pressed oil, which not only ensures the quality of the grease, but also removes the odor contained in the grease and makes it acceptable to users.
The use of oil machinery for deodorization work requires equipment to have a certain process and technology, pure triglyceride fatty acid is a colorless and odorless substance, but because the oil will have its own "exclusive taste", and the smell is not very good, most people directly call it "smell", it is due to the oxidation of the oxidation products to form oxygen compounds, and then decompose into aldehydes to generate the taste, just like the solvent taste.
Therefore, the deodorization process of grease machinery is a very important link, which can remove the flavor in the grease, but before that, it needs to carry out hydration, alkali refining and decolorization work, so that it can be carried out only after it has the corresponding conditions, so that the taste will be cleared more cleanly. Normally, the common deodorization method used by operators is the vacuum vapor deodorization method, which is simple in principle and has a good effect, so it is favored by everyone.
