The development of drying in tarditional Chinese herbal medicine

Chinese herbal medicine has been a treasure of Chinese culture for thousands of years, and it continues to play a significant part in the growth of the Chinese medical sector. Compared to western medicine, Chinese medicine offers distinct benefits in training the human body since it is less harmful, has fewer side effects, and treats both the symptoms of an illness and its underlying cause. Today, microwave technology is employed extensively across a wide range of industries, including Chinese herbal medicine.

Chinese herbal medicines are often dried after collection to preserve their therapeutic properties and increase shelf life. with the development of Chinese herbal medicine. In China, drying herbs has an ancient tradition. Because it includes alkaloids, saponins, anthraquinones, flavonoids, volatile oils, etc., Chinese herbal medicine has the characteristics of heat sensitivity, oxidability, and lucifuge. This makes it more challenging to guarantee drying quality. The focus of current studies on the drying of Chinese herbal medicines is on contrasting traditional drying methods with contemporary drying technologies and looking for new effective drying techniques.

Traditional Sun Drying Method:

Herbs can be traditionally dried by laying them out in the sun to reduce their moisture content (MC). It's been around for a while and is still in use. It requires extensive drying time, which is impossible in the rain and at night. Any lag results in increased fungal growth and respiration, which causes losses and discoloration. Limited capacity and labor-intensive. Controlling the temperature is challenging. The quality of dried herbs might suffer, and their active components can be greatly lost if they are overheated. Only herbs with little to no added value can be used.

Traditional Oven-Drying Method:

Utilize high pressure and temperatures to sterilize the drug, which calls for a huge workshop as well as pricey air conditioning equipment. Additionally, sterilization should be done at high pressure and temperature. It transfers external heat power to internal heat power. It takes a long time to uniformly heat herbs. According to studies, the structure of the plant does not lend itself to high-temperature drying well as pricey air conditioning equipment. Additionally, sterilization should be done at high pressure and temperature. It transfers external heat power to internal heat power. It takes a long time to uniformly heat herbs. According to studies, the structure of the plant does not lend itself to high-temperature drying. Therefore, after being exposed to high temperatures, herbal medicines lose their active components, potentially reducing their efficacy and value. In addition to not being able to heal individuals, this also harms their health.

New Technology Microwave Drying Method:

Microwave methods are currently used in the drying, sterilizing, and extraction processes for Chinese herbal medicine due to advances in technology. A type of electromagnetic wave with significant penetration is the microwave. The herbs themselves become the heat source throughout the heating process, absorbing both inner and outer microwave energy. Due to the low temperature of microwave drying, the Chinese herb medicine may be dried uniformly and fully in a short amount of time while maintaining its natural qualities and color. Equipment for microwave drying may complete the drying and sterilizing processes concurrently. It may eradicate germs and microorganisms to stop mildew during storage and increase shelf life. The traditional drying method's shortcomings—long drying times, high energy and labor costs, and low-quality herb drying—are not only addressed by the microwave drying technology, which also demonstrates its distinguishing characteristics of complete, even drying and sterilization. Both the drying requirements for Chinese herbal medicine and the environmental preservation topic are suitably satisfied.

In order to achieve drying in a short amount of time with good drying results, Azeus produces industrial microwave drying equipment for Chinese herbal medicine.
