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 lar

Embodiment 1

[0011] Spread 50kg of Cordyceps militaris, with a thickness of 2.0cm, and set up ultraviolet lamps, ozone generators, refrigeration air conditioners and industrial dehumidifiers in the environmental control room. The material was dehumidified and dried for 2 hours; then, the Cordyceps militaris was transferred to an electric blast circulation drying oven for drying, and the temperature of the oven was controlled at 50°C, and it was taken out after drying for 12 hours.

[0012] The following table is a comparison of the monitoring report of Cordyceps militaris using the traditional drying method and the drying method of the present invention.

Embodiment 2

[0015] Spread 50kg of Cordyceps militaris (artificial fruiting body) with a thickness of 4.0cm, and place it in an environment control room. The environment control room is equipped with ultraviolet lamps, ozone generators, refrigeration air conditioners and industrial dehumidifiers. The refrigeration air conditioners control the ambient temperature at 20°C. The industrial dehumidifier controls the ambient humidity to 40%, dehumidifies and dries the Cordyceps militaris for 20 hours; then transfers to an electric blast circulation drying oven for drying, the temperature is controlled at 60°C, and takes out after drying for 10 hours.

Embodiment 3

[0017] Spread 50kg of artificial cicadas, with a thickness of 6.0cm, and place them in the environment control room. The environment control room is equipped with ultraviolet lamps, ozone generators, refrigeration air conditioners and industrial dehumidifiers. Control the ambient humidity to 50%, and dehumidify and dry Cordyceps militaris for 24 hours; then transfer to an electric blast circulation drying oven for drying, the temperature is controlled at 70°C, and take out after drying for 2 hours.

[0018] In addition, the drying method of the present invention is also applicable to the drying of food, medicine, pollen and the like.

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 ...
