dehumidifier in the warehouse of traditional Chinese medicine and technical trends of humidity control scheme in the warehouse of traditional Chinese medicine. Recently, there is a lot of rain and weather, and many customers report that the Chinese medicine pieces stored in the warehouse have a lot of mildew. Through investigation, the Chinese medicine pieces stored in the warehouse with strict temperature and humidity control can greatly reduce the occurrence of mildew

Dehumidifier and humidity control scheme for TCM decoction pieces warehouse

The temperature and humidity control scheme for the Chinese herbal medicine slices warehouse: the air conditioner+dehumidifier method is selected to control the temperature and humidity, which is cost-effective; Another is to use a constant temperature and humidity machine to control temperature and humidity, but the cost is high

Reasons for the mildew of Chinese herbal pieces:

1. Humidity: humidity is an essential condition for mold growth. Generally, the internal water content of prepared slices of traditional Chinese medicine is controlled at 7% - 13%. During the factory inspection, the internal water content strictly conforms to the pharmacopoeia standard. But in the plum rain season, the air is humid, and the Chinese herbal medicine slices absorb the water in the air, so the water content will increase. Generally, when the relative humidity is more than 75% RH, most of the prepared slices of traditional Chinese medicine increase the water content by gradually absorbing the water in the air, and the prepared slices of traditional Chinese medicine are prone to mildew and deterioration

Sauna day in late summer and early autumn is the key period for the storage of medicinal materials. The weather is hot, and the relative humidity of the air is greater than 75% RH. This weather requires that the storerooms storing medicinal materials must be equipped with necessary dehumidification and cooling equipment

2. Temperature: The mildewed microorganisms that cause the mildew of the prepared slices of traditional Chinese medicine are most suitable for reproduction and growth at 25-35 ℃. If the prepared slices of traditional Chinese medicine are stacked too high and too tight, the internal tissues and cells of the medicine will be strengthened, generating heat, which will cause mildew

In a word, the storage and preservation of Chinese herbal pieces must adopt various scientific preservation methods according to the variety, stock, season and equipment conditions, adhere to the principle of "prevention first, prevention combined", avoid moth eaten, reduce the waste of social resources, ensure the quality of Chinese herbal pieces, and ensure the safety and effectiveness of drug use

Especially in rainy seasons, pay attention to the change of air humidity, and focus on the varieties that are prone to moisture absorption and mildew. Purchase frequently. While fully ensuring the clinical use of drugs, the storage time of perishable Chinese herbal pieces in the warehouse should be shortened as much as possible. In addition, the cleanliness of the warehouse is the basis of all prevention and control work, and is also an important measure to implement the Chinese medicine preservation policy of "prevention first, prevention and control simultaneously". It is also essential to keep the warehouse and its surrounding environment clean for storing Chinese herbal medicines and Chinese herbal pieces
