Embodiment 1

[0025] Example 1 Deodorization of black soybean distillate

[0026] Add 200g black soybean distillate in the feeder of molecular distillation device (MD-S80 type, produced by Guangzhou Hanwei Air-conditioning Electromechanical Co., Ltd., feeder volume 300ml, evaporation area 0.01 square meter, wiper rotating speed 100~1000rpm), Turn on the raw material preheating device, raise the temperature to 70°C, and keep it at a constant temperature. Turn on the cooling device, keep the cooling temperature at 40°C, add liquid nitrogen to the cold trap, turn on the vacuum pump to make the operating pressure of the system reach 40Pa, turn on the precision constant temperature tank for evaporating materials to heat the heat transfer oil, so that the system temperature can be stabilized at the required level The evaporation temperature was 80°C, and then the feed valve was opened, the feed rate was 80g / h, and the rotating speed of the wiper was 250rpm. After the distillation process ended, 2...

Embodiment 2

[0028] Example 2 Deodorization of black soybean distillate

[0029] The molecular distillation device is the same as in Example 1.

[0030] Add 200g black soybean distillate in feeder, open raw material preheating device, be warming up to 110 ℃, and keep constant temperature. Turn on the cooling device, keep the cooling temperature at 20°C, add liquid nitrogen into the cold trap, turn on the vacuum pump to make the operating pressure of the system reach 3Pa, turn on the precision constant temperature tank for evaporating materials to heat the heat transfer oil, so that the system temperature can be stabilized at the required level The evaporation temperature was 110° C., then the feed valve was opened, the feed rate was 90 g / h, and the rotating speed of the film wiper was 700 rpm. After the distillation process ended, 33 g of light fractions collected were discarded to obtain 167 g of heavy fractions. At this time, the special odor of the heavy distillate has been removed.

Embodiment 3

[0031] Example 3 Decolorization of black soybean distillate

[0032] In the feeder of molecular distillation device (feeder volume 300ml, evaporation area 0.01 square meter, wiper rotating speed 100~1000rpm), add the deodorized heavy fraction 169g of embodiment 1 as raw material, open raw material preheating device, Raise the temperature to 160°C and keep it at a constant temperature. Turn on the cooling device, keep the cooling temperature at 30°C, add liquid nitrogen to the cold trap, turn on the vacuum pump, so that the operating pressure of the system does not exceed 10Pa, turn on the precision constant temperature tank for evaporating materials to heat the heat transfer oil, so that the temperature of the system is stable at the specified temperature. The required evaporation temperature is 160°C, then the feed valve is opened, the feed rate is 70g / h, and the rotating speed of the wiper is 500rpm. After the distillation process ends, 128g of light fraction and 41g of heav...

Abstract

This invention relates to a refine method for deodorizing Glycine max deflegmation oil. The invention adopts molecule short range distillation method to effectively separate component with special odour and dark brown color from Glycine max deflegmation oil, thereby obtaining light colored purified product without odour. The invention without the necessity for chemical organic solvents and specific installation has simple technology, short process time, simple operation, no enviromental pollution, and low cost; and dose not change the pharmacologic effect of processed odorless Glycine max deflegmation oil, and can improve dependance of patients.

Description

Technical field: [0001] The invention relates to a method for refining black soybean distillate oil. Background technique: [0002] Black soybean distillate is a black viscous tar obtained by heating and dry distillation of black soybeans at 400-500 ° C. It is a high-boiling mixture composed of different components. Black soybean distillate oil can relieve itching, anti-inflammatory, astringent and regenerate cutin. Clinically, it is often used in external pharmaceutical preparations such as neurodermatitis, subacute, chronic dermatitis and chronic eczema. [0003] Although the clinical curative effect of black soybean distillate oil is clear, but because it is a tar substance, the prepared preparation is dark brown, and it is easy to stain clothes, which makes it difficult for patients to accept it and limits its clinical use. [0004] The method of prior art, as adopting conventional distillation method etc., can't remove the blackness of black soybean distillate. The 2...
