How can Chinese medicinal materials be dried without discoloration- Dehumidifier for drying traditional Chinese medicine

How can Chinese medicinal materials be dried without discoloration? News of dehumidifier for drying Chinese herbal medicines: It is understood that most Chinese herbal medicines have high water content after harvest, reaching more than 70%; In the process of processing, transportation, storage, sales and other links, mildew, moth eaten, discoloration and other phenomena often occur, which is not easy to keep for a long time; The effective ingredients of the drug are also decomposed and lost, seriously affecting the quality and efficacy of traditional Chinese medicine; According to statistics, especially in the tropical and subtropical regions, the loss rate is as high as 35% - 45%. Therefore, it is very important to dry or dry Chinese medicinal materials in a timely and effective manner in order to enable them to be preserved for a long time, as well as the medicinal price and efficacy

It is appropriate to keep the moisture content of the dried medicinal materials at 10%~15%; For example, when the water content of red dates is controlled at 12%~17%, Dangshen 11%~16%, bitter almond 6%~8%, Shashen 12%~15%, Astragalus 11%~14%, the quality will not change in the processing, transportation, storage, sales and other processes and in all links. In the past, traditional natural air drying methods were mostly used to dry Chinese herbal medicines, such as drying them in the sun or drying them by spreading them. However, in the absence of the sun or in the wet season, the effect of natural air drying will be slow and even return to the damp

For this reason, different drying processes and equipment are required for drying according to different Chinese medicinal materials; However, no matter what drying process and equipment are used, special attention should be paid to the control of temperature and humidity in the drying process. It is not easy to dry when the temperature is low, and it is easy to change color when the temperature is too high, affecting the quality and efficacy; For example, the drying temperature of rhubarb shall not exceed 60 ℃, and the color will darken and the quality will be degraded if the temperature is higher; When drying flowers, the temperature should not be too high, for example, the drying temperature of chrysanthemum should be controlled at 55~65 ℃; Therefore, the vast majority of traditional Chinese medicine should use low-temperature drying process and equipment

In addition, humidity control is a problem; During the drying process of traditional Chinese medicine, its internal moisture will continuously evaporate to the air in the drying room, resulting in higher and higher humidity. If it is not removed in time, it will not only easily discolor the traditional Chinese medicine and affect its drying quality; Moreover, the drying efficiency will be greatly reduced, which will undoubtedly increase the drying cost of traditional Chinese medicine; At present, the dehumidification method adopted is simple and extensive "direct discharge" - direct discharge of heat and steam from the drying room by using the dehumidification hole and the dehumidification fan. This method is indeed effective, but it also consumes a huge amount of heat

However, there are now_ G dehumidifier for drying traditional Chinese medicine and ZD series high-temperature dehumidifier, these problems have been well solved; We have found a better way to dry traditional Chinese medicine. No matter what kind of traditional Chinese medicine is, it is not limited by the season and site. It can achieve the goal of rapid drying. The effect is the same as that of natural air drying, which not only effectively ensures the drying quality and efficacy of traditional Chinese medicine, but also greatly speeds up its drying efficiency

For example, due to the high humidity in the drying process of a drying room, the method of ventilation and moisture removal is adopted, and the drying time takes 24 hours; And_ After G dehumidifier for drying traditional Chinese medicine and ZD series high-temperature dehumidifier, the humidity in the drying room can be rapidly reduced without exhausting heat; Now, it only takes 16 or 12 hours to achieve the original 24-hour drying effect, greatly reducing the operating cost of the drying room. It has been widely used in drying rooms of factories and enterprises all over the country, and its effect has been recognized by all users

The working environment temperature of general refrigerated dehumidifiers is 5-38 ℃. If the temperature exceeds 38 ℃, the dehumidifiers will be automatically protected and shut down. However, in the material drying room and drying room, the indoor temperature generally exceeds 40 ℃, so the general refrigerated dehumidifier cannot work in this environment. At present, the material drying method of general enterprises is to forcibly discharge the hot and humid air in the drying room through the fan. In this way, the heat in the room is also discharged out of the room

For the need of energy-saving dehumidification and drying in drying rooms and drying rooms, electrical appliances are specially developed_ G dehumidifier for drying traditional Chinese medicine and ZD series high-temperature dehumidifier (applicable to dehumidification in the environment where the indoor temperature is higher than 38 ℃ but lower than 55 ℃); It can be widely used for heating, curing, drying and dehydration of materials and products in pharmaceutical, chemical, food, light industry, heavy industry and other industries. For example, wood, dried fruits, edible fungi, agricultural and sideline products, paper products, APIs, crude drugs, Chinese herbal pieces, powders, granules, granules, pigments, dyes, dehydrated vegetables, dried fruits and melons, sausages, plastic resins, electrical components, baking paints, etc
