Product Description:
According to the customer's requirements for animal oil types, daily processing volume, oil product standards and other requirements, processing and customization, specifications, sizes, number of refining tanks, and product prices are different.
Can undertake:
1 ton-500 ton lard, butter, mutton, chicken and duck oil, fox oil and other production line equipment
Product advantages: Through dephosphorization, decolorization, deacidification, deodorization and other processes, the crude oil can meet the national national standard oil quality standards. After refining, the refined oil has a clear color and is stored for a long time without mucus, no deterioration, and no peculiar smell.
1. Animal oil degumming and hydration
The colloidal impurities in crude oil are mainly phosphorus. The presence of gelatinous substances such as phospholipids not only reduces the quality of oil, but also promotes transitional emulsification between oil and lye during the alkali refining and deacidification process, which increases the difficulty of separation of saponins and aggravates the loss of neutral oil. Therefore, it should be removed first.
2. Deacidification of animal oil
Oil deacidification is mainly to remove free fatty acids in crude oil, as well as a small amount of colloids, pigments and trace metal substances in the oil. Deacidification operation is one of the important factors that directly affect the yield and quality of oil refining. The most widely used in industrial production is the alkali refining and deacidification method.
3. Animal oil decolorization
The color and luster of oil and some other impurities must be decolorized to meet product quality standards. At the same time, it provides more favorable conditions for deodorization and refining. Decolorization must meet the final requirements of the color and luster of the product; remove relevant pigments and quantitative metals; further remove residual traces of saponins, phospholipids and other colloidal impurities and certain odor substances in the oil; remove polycyclic aromatic hydrocarbons and residual pesticides; reduce oil quality Oxidation value.
4. Animal oil deodorization
The purpose of oil deodorization is to remove the odor-causing substances in the oil and other substances that are easy to volatilize, improve the smell and color of the oil, and improve the stability of the oil. The peculiar smell of oil, the peculiar smell produced during decolorization, the clam smell produced by the oxidation of oil, etc. In the deodorization stage, these unpleasant odors are required to be sprayed directly into the steam distillation at high vacuum and high temperature to remove them.
