Embodiment 1

[0036] Get 20 kilograms of Radix Astragali with a water content of 20% and pack it into an expansion tank, heat it to the temperature in the tank and control it at 79° C., and the pressure in the tank rises to 0.2 MPa for 10 minutes. Subsequently, quickly open the pressure reducing valve connecting the expansion tank and the vacuum tank (the vacuum tank has been pre-evacuated), instantly reduce the pressure to -0.09MPa, and cool down to room temperature naturally. The vacuum tank described is 5 times larger than the expansion tank.

[0037] The extraction rate of astragaloside IV in 60% ethanol extraction of puffed Astragalus membranaceus was 17% higher than the corresponding extraction rate of 60% ethanol extraction of unexpanded Astragalus membranaceus.

[0038] The extraction rate of astragaloside IV after water extraction of expanded Astragalus is 30% higher than the corresponding extraction rate of water extraction of unexpanded Astragalus.

Embodiment 2

[0040] Get magnolia flower buds, process to make the water content 10%, get 20 kg and put them into an expansion tank, heat until the temperature in the tank is controlled at 60 ° C, the pressure in the tank rises to 0.5 MPa, and the time is maintained for 30 minutes. Then, quickly open the pressure reducing valve connecting the expansion tank and the vacuum tank (the vacuum tank has been evacuated in advance), drop the pressure to -0.04MPa instantly, cool down to 25°C, and maintain it for 10 minutes. The vacuum tank described is 8 times larger than the expansion tank.

[0041] The above-mentioned puffed magnolia flower buds are added to a steam distillation kettle, 40% water is added in proportion to the weight of medicinal materials for wetting, and then water vapor is introduced, and continuous distillation is carried out for 20 hours, and the volatile oil is obtained after the oil and water are separated.

[0042] Contrast: extract magnolia flower buds according to the met...

Embodiment 3

[0045] Take 20 kg of Bupleurum bupleurum and rinse it with tap water, then slice it into slices with a thickness of 3 cm. After drying, the water content is controlled at 30%. Put the dried Bupleurum erythroxylum into an expansion tank, and control the temperature in the tank by heating. At 30°C, the pressure inside the tank rose to 0.9 MPa and was maintained for 20 minutes. Then, quickly open the pressure reducing valve connecting the expansion tank and the vacuum tank (the vacuum tank is pre-evacuated). Due to the instantaneous pressure drop in the expansion tank, the moisture inside the Chinese herbal medicine will be flashed, and the pressure will be reduced to -0.07MPa in an instant, and the temperature will be lowered to 30°C. , and maintain for 30 minutes. Continue to maintain heating and dehydration under negative pressure conditions for a period of time, then lower the temperature to below 20°C. The vacuum tank described is 9 times larger than the expansion tank.

Abstract

The invention discloses a vacuum bulking manufacturing technique of traditional Chinese medicine, which is characterized by the following: adopting vacuum bulking technique to control and select the shape, size and moisture content of the traditional Chinese medicine to generate many pores at the cell wall of the traditional Chinese medicine; lixiviating and distilling the cell content to improve the extracting quantity of effective component or ingredient; fitting for extracting volatile oil component in the traditional Chinese medicine; opening a new path for drug value.

Description

technical field [0001] The invention relates to a vacuum puffing processing technology for Chinese medicinal materials, which belongs to the field of processing Chinese medicinal materials. Background technique [0002] Traditional natural medicines, such as traditional Chinese medicine, can not only provide satisfactory curative effects for the treatment of viral diseases, cardiovascular and cerebrovascular diseases, metabolic diseases and various geriatric diseases, but also have great advantages in health care and longevity. Low, and easy to develop and utilize, the global traditional medicine fever continues to heat up, and it also makes returning to nature and advocating the use of natural medicines an important trend in the development of medicine in the current era. [0003] However, the relatively backward extraction process of Chinese medicinal materials has seriously affected the quality and clinical efficacy of traditional Chinese medicine. Chinese medicinal mater...
