Drying method of Chinese medicinal material

Abstract

The invention discloses a drying method of a Chinese medicinal material. The method comprises the following steps of: (1) uniformly spreading a Chinese medicinal material in an environment control room with thickness of between 2.0 and 6.0cm; setting an ultraviolet lamp, an ozone generator, a refrigeration air conditioner and an industrial dehumidifier, controlling the environment temperature to be between 10 and 22 DEG C by the refrigeration air conditioner, controlling the environment humidity to be between 10 and 50 percent by the industrial dehumidifier, and dehumidifying and drying the Chinese medicinal material for 2 to 24 hours; and (2) transferring the Chinese medicinal material into an electrothermal draught circulating drying oven for drying at a temperature of between 50 and 70 DEG C for 2 to 12 hours. The drying method improves the product quality, is applicable to drying treatment of massive Chinese medicinal materials, as well as foods, medicaments, pollen and the like.

Description

technical field [0001] The invention belongs to the technical field of drying methods for Chinese medicinal materials. Background technique [0002] At present, when the precious medicinal materials Cordyceps sinensis, Cordyceps militaris (Cordyceps militaris), Cicada flower (also known as Cordyceps), and various types of pollen are dried, due to the temperature sensitivity of various active ingredients, too high a temperature will affect and destroy the active ingredients (or nutrition) ingredients), so the drying temperature is generally controlled below 60°C or even lower. When drying at 60°C, due to the high humidity of medicinal materials and pollen, and the temperature is suitable for the proliferation and growth of microorganisms, during the drying process, it will often cause mildew of Chinese medicinal materials and pollen, resulting in serious microbial limit of the finished product. affect the quality. Moreover, the energy consumption of electricity used in ...

AI Technical Summary

Problems solved by technology

When drying at 60°C, due to the high humidity of medicinal materials and pollen, and the temperature is suitable for the proliferation and growth of microorganisms, during the drying process, it will often cause mildew of Chinese medicinal materials and pollen, resulting in serious microbial limit of the finished product. affect quality

Moreover, the power consumption used by this method is relatively large, the drying time is long, the equipment investment is large, and a large amount of drying requires a large oven to be used for a long time

[0003] At present, most of the Cordyceps, Cordyceps militaris, Cicada and related solid fermentation culture products sold in the market adopt the traditional drying method, the appearance is obviously black, and the quality has a certain impact

Moreover, the energy consumption required for drying is large, and the investment in drying equipment and other equipment is relatively large.
