Embodiment 1

[0016] 1) Pretreatment: Take the belly fat of the black wind snake, wash it with pure water 3 times to remove impurities such as snake skin and fiber, and mash it to 0.5-1cm;

[0017] 2) Filling: the above-mentioned crushed snake fat is evenly filled into supercritical CO 2 In the extraction kettle of the extractor, and close the extraction tank;

[0018] 3) Extraction: open the gas cylinder, liquid CO 2 After cooling, it is pressurized to 20MPa by a high-pressure pump, and then heated to 45℃ by a heating kettle, CO 2 Enter the extraction kettle from the bottom for extraction, dissolving CO from the black wind snake oil 2 Enter the separation kettle with a pressure of 6MPa and a temperature of 35°C through the pressure reducing valve, which causes the solubility of grease to decrease and precipitate and deposit on the bottom of the separation kettle;

[0019] 4) Discharging: when it reaches 12kgCO after 6 hours 2 Stop the extraction during the circulating amount and open the discharge...

Embodiment 2

[0024] 1) Pretreatment: Take the belly fat of the black wind snake, wash it with pure water 3 times to remove impurities such as snake skin and fiber, and mash it to 0.5-1cm;

[0025] 2) Filling: the above-mentioned crushed snake fat is evenly filled into supercritical CO 2 In the extraction kettle of the extractor, and close the extraction tank;

[0026] 3) Extraction: open the gas cylinder, liquid CO 2 After cooling, it is pressurized to 20MPa by a high-pressure pump, and then heated to 50℃ by a heating kettle, CO 2 Enter the extraction kettle from the bottom for extraction, dissolving CO from the black wind snake oil 2 The pressure reducing valve enters the separation kettle with a pressure of 8MPa and a temperature of 40°C, which causes the solubility of grease to decrease and precipitate and deposit on the bottom of the separation kettle;

Abstract

The invention provides a method for preparing black snake oil. The method comprises the following steps: mashing adipose tissues of black snakes; uniformly filling the mashed adipose tissues in an extraction kettle; pressurizing liquid CO2 to a necessary pressure via a high pressure pump; heating the liquid CO2 to a set temperature via a heating kettle; conveying the liquid CO2 into the extraction kettle from the bottom for extraction; conveying the CO2 dissolved with black snake grease into a separation kettle with lower pressure through a reducing valve to reduce the solubility, so that a solute separates out and deposits on the bottom of the separation kettle, the CO2 is hermetically and circularly used in the entire device; and stopping extracting when a set CO2 circulation volume is up, discharging a product in the separation kettle, and filtering to obtain a black snake oil product. The product prepared by the preparation method provided by the invention is high in oil yield, light in color, high in transparency, free of precipitates and suspended solids, small in viscosity and high in linoleic acid content.

Description

technical field [0001] The invention belongs to the technical field of animal oil extraction, and in particular relates to a preparation process of black snake oil. Background technique [0002] Snake oil is rich in natural active substances and antibacterial ingredients, has super penetrating power, can directly penetrate human skin, promote skin cell metabolism, and enhance skin immune regulation function; it is a substance that is both rich in nutrition and beneficial to health care. Or the folks like to use snake oil for health care, which has a good effect on regulating endocrine disorders, moisturizing the intestines and laxatives, beautifying the skin, preventing skin aging, and preventing vascular sclerosis. [0003] Snake oil contains 12 kinds of fatty acids, mainly unsaturated fatty acids such as linoleic acid and linolenic acid, and glycerol palmitic acid. Among them, linoleic acid, the most unsaturated fatty acid, will be oxidized if the temperature is too high ...
