Embodiment 1

[0021] Example 1 Deodorization of black soybean distillate

[0022] Add 200g black beans to the feeder of the molecular distillation device (MD-S80 molecular distillation device produced by Guangzhou Hanwei Air-conditioning Electromechanical Co., Ltd., the feeder volume is 300ml, the evaporation area is 0.01 square meters, and the rotating speed of the film wiper is 100rpm~1000rpm). For distillate oil, 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 rot...

Embodiment 2

[0023] Example 2 Deodorization of black soybean distillate

[0024] The molecular distillation device is the same as in Example 1.

[0025] 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.

Abstract

This invention relates to a method for deodorizing Glycine max deflegmation oil. The invention adopts molecule short range distillation method to effectively separate component with special odour from Glycine max deflegmation oil, thereby eradicate odour. The invention without the necessity for chemical 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 deodorizing 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°C to 500°C, and is a mixture of different components. Black soybean distillate oil can relieve itching, anti-inflammatory, astringent and regenerate cutin. Black soybean distillate oil has similar effects to other tar preparations. Low concentration (3%-5%) can promote keratin formation; 10%-30% concentration has keratin exfoliation, but less irritation. Clinically, it is often used in external pharmaceutical preparations such as neurodermatitis, subacute, chronic dermatitis and chronic eczema. [0003] Black soybean distillate has a peculiar smell, which makes it difficult for patients to accept and limits its clinical use. [0004] The methods for refining black bean distillate in the prior art, such as conventional distillat...
