Embodiment 1

[0028] 1) Preparation of mink crude oil:

[0029] ①Take 10 kg of subcutaneous and abdominal fat of slaughtered mink, add 2 times (mass) of cold water containing 0.5% sodium benzoate and soak for 30 minutes, and keep stirring, perform cold washing, pour off the soaking water, repeat the above operation 3 times until The washing water is clear,

[0030] ② Add 1.5 times (mass) of 2% saline to the washed crude oil, heat to 80°C, keep warm and stir for 40 minutes, remove the residue, separate the oil and water while it is hot, discard the water phase, and collect the oil part. Then add 1.5 times (mass) of 2% salt water to the oil residue, heat to 90°C, keep warm and stir for 40 minutes, remove the residue and squeeze it, add the extruded oil into the boiled water-oil mixture, and Carry out oil-water separation, the oil phase of 2 separations is combined, obtain about 9 kilograms of crude oils.

[0031] 2) washing

[0032] Add 1.5 times (mass) 0.3mol / L of H to the crude o...

Embodiment 2

[0038] 1) Preparation of mink crude oil:

[0039] ①Take 15 kg of subcutaneous and abdominal fat from slaughtered mink, add 2 times (mass) 0.5% sodium benzoate to soak in cold water for 30 minutes, stir continuously, and perform cold washing. Pour off the soaking water and repeat the above operation 5 times until the washing water is clear.

[0040] ② Add 1.5 times (mass) 2% salt water to the washed crude oil, heat to 65°C, keep stirring for 40 minutes, remove the residue, separate the oil and water while it is hot, discard the water phase, and collect the oil part. Add 1 times (mass) 2% salt water to the oil residue, heat to 65°C, keep warm and stir for 40 minutes, remove the residue and squeeze it, add the extruded oil into the boiled water-oil mixture, and carry out Oil and water were separated, and the oil phases separated for two times were combined to obtain about 13.5 kg of crude oil.

Embodiment 3

[0048] 1) Preparation of mink crude oil:

[0049] ①Take 10 kg of subcutaneous and abdominal fat from slaughtered mink, add 2 times the amount of 0.5% sodium benzoate to soak in cold water for 30 minutes, and keep stirring for cold washing. Pour off the soaking water and repeat the above operation 4 times until the washing water is clear.

[0050] ② Add 1.5 times (mass) 2% saline to the washed crude oil, heat to 70°C, keep warm and stir for 40 minutes, remove the residue, separate the oil and water while it is hot, discard the water phase, and collect the oil part. Add 1 times the amount of 2% salt water to the oil residue, heat it to 70°C, keep it warm and stir for 40 minutes, remove the residue and squeeze it, add the extruded oil into the boiled water-oil mixture, and carry out oil-water separation together. The 2 separated oil phases were combined to obtain about 9 kg of crude oil.

Abstract

The invention relates to a simple refining method of mink oil. The invention aims to provide a simple refining method of mink oil and overcome the problems of the prior art, namely large equipment investment, complicated procedures and high energy consumption and cost. The aim of the invention is realized by the simple refining method of mink oil. The simple refining method of mink oil comprises the following steps: 1) preparing crude mink oil; 2) washing: washing the crude mink oil with acidic solution at 65-80 DEG C to obtain pickling mink oil, then washing the pickled mink oil with saturated salt water to ensure that the solution is neutral, washing the obtained solution with alkaline solution to obtain alkali-washing mink oil and washing the alkali-washing mink oil with saturated saltwater to ensure that the solution is neutral and obtain primary refined oil; and 3) deodorizing with deodorant: adding polyphenol plant deodorant in the primary refined oil, keeping the temperature to 65-80 DEG C to stir for 30-60 minutes and then keeping the temperature to filter and obtain secondary refined oil, wherein the polyphenol plant deodorant accounts for 3%-10% of the primary refined oil.

Description

technical field [0001] The invention relates to the technical field of mink oil refining, in particular to a simple mink oil refining method. Background technique [0002] Mink is a precious fur animal. It is cultivated in all parts of my country. The analysis results show that the fat composition of mink oil contains more unsaturated fatty acids, of which the content of oleic acid, linoleic acid and linolenic acid reaches about 46%, and the melting point is low. (about 12-35°C), so it has good penetration. However, because of its special odor, it is difficult to use and becomes an obstacle to improving the economic benefits of the mink industry. The smell of mink oil is caused by its own metabolism, mainly from the secretion of the anus, and its main components are amines, mercaptans, indoles and some lower fatty acids. [0003] An invention with the patent No. 89107715.4 discloses a method for refining mink oil. The process of this method includes: 1. Water extraction, ...
