Environment-friendly extraction method for animal oil and fat

Abstract

The invention relates to an environment-friendly extraction method for animal oil and fat. The method includes animal oil and fat crushing, smelting, oil residue separation, meat residue squeezing, filtering, peculiar smell deodorization and oil purification. The animal oil smelting and extraction form assembly line work, the whole animal oil extraction process has the characteristics of simple and convenient operation control and high work efficiency, and the produced animal oil and fat have few impurities, good oil color and high quality.

Description

technical field [0001] The invention belongs to the technical field of animal oil refining, and in particular relates to an environment-friendly extraction method of animal oil. Background technique [0002] Animal oil, that is, animal fat, is the fat of animals. Animal oil for human consumption generally comes from pigs, cattle, fish, etc., and can be used to process food to make the food have the fresh flavor of meat. Pairing it with vegetarian food that eats a lot of oil, such as eggplant, radish, etc., will have the effect of whetting the appetite and promote the body's absorption of food nutrients, especially vitamins. Animal oil has a more fragrant taste and can promote the absorption of fat-soluble vitamins A, D, E, K, etc. In addition, cholesterol in animal oil is also an important component of human tissue cells and an important raw material for the synthesis of bile and certain hormones.

Problems solved by technology

[0003] At present, the oil refining equipment commonly used in most animal oil processing plants in my country is "open type fire cooking pot". Many, unstable quality, high acid value, easy to deteriorate, it is difficult to ensure that the product quality reaches food-grade standards; a small number of enterprises have developed vacuum melting equipment for animal oil in order to solve the above problems and respond to the national environmental protection requirements, but the above-mentioned equipment exists The following defects: 1. The work efficiency is still low, and the average production time of a can of animal essential oil is 4 to 6 hours. 2. The outlet of the animal oil melting tank is easy to block; resulting in the inoperability of the follow-up section; 3. The melting tank is stirred 4. Due to the limitation of the volume of the smelting tank, the output is limited. When multiple smelting tanks are connected in parallel, firstly, the normal operation of the follow-up equipment cannot be guaranteed, and secondly, the quality of the animal fat is unstable and oil color difference
