Drying method of traditional Chinese medicine fluid extract

Abstract

The invention discloses a drying method of traditional Chinese medicine fluid extract. The method comprises the following steps: S1, putting medicine liquid extracted from traditional Chinese medicinal materials into a tray, then putting the tray containing the medicine liquid into a thermotank for heating and heat preservation, and enabling the temperature of the medicine liquid to be consistentwith the temperature in the thermotank before the medicine liquid is taken out of the thermotank; S2, taking out the tray containing the medicine liquid from the thermotank, and putting the tray intoa microwave vacuum dryer for drying and concentrating to obtain traditional Chinese medicine fluid extract. In the step S1, the depth of the medicine liquid in the tray is 40-50 mm, the temperature inthe thermotank is 40-50 DEG C, and the placement time of the medicine liquid in the thermotank is 40-60 minutes; in the step S2, the vacuum degree in the microwave vacuum dryer is -0.073 MPa or above, the drying temperature is 60-75 DEG C, and the drying time is 60-90 minutes. The medicine liquid extracted from the traditional Chinese medicinal materials is dried and concentrated by using a microwave vacuum heating and drying method, so that the medicine liquid extracted from the traditional Chinese medicinal materials can be uniformly and quickly dried and concentrated, and effective components in the traditional Chinese medicinal materials cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of production of liquid extracts of Chinese medicines, in particular to a drying method of liquid extracts of Chinese medicines. Background technique [0002] Traditional Chinese medicine liquid extract is obtained by drying and concentrating the medicinal liquid extracted from Chinese medicinal materials. A large amount of heat is required for drying and concentrating the medicinal liquid of traditional Chinese medicine. Commonly used drying methods include electric heating drying method, microwave heating drying method and vacuum drying method. The electric heating drying method is the most primitive drying method, the equipment is the simplest, but the energy consumption is the highest, and the controllability and uniformity of the heating temperature are poor, which is easy to cause damage to the active ingredients in the liquid medicine. Compared with the electric heating drying method, the microwave he...

Problems solved by technology

The electric heating drying method is the most primitive drying method, the equipment is the simplest, but the energy consumption is the highest, and the heating temperature is poor in controllability and uniformity, which is easy to cause damage to the active ingredients in the liquid medicine

Compared with the electric heating drying method, the microwave heating drying method and the vacuum drying method consume less energy. The microwave heating drying method has better heating uniformity, but the heating temperature controllability of the microwave heating drying method is poor, and it is easy to generate high temperature. The active ingredients in the liquid medicine cause damage, and the temperature required by the vacuum drying method is low, which has a good protective effect on the liquid medicine, but the heating uniformity during drying is not as good as that of the microwave heating drying method
