Traditional medicinal material drying equipment uses coal as fuel to burn and generate clean hot air as the drying medium to absorb the moisture in the traditional Chinese medicine, discharge the humid air that reaches a certain moisture content, and cycle back and forth to achieve the moisture required by the traditional Chinese medicine. The characteristics are that it is time-consuming and labor-intensive, cannot fully meet the requirements for drying medicinal materials, has poor sterilization properties, and uses coal as fuel to pollute the environment.

Microwave drying equipment is a Chinese herbal medicine drying and processing equipment developed using microwave drying technology. It retains the active ingredients in Chinese medicinal materials to the greatest extent, and at the same time can kill various molds and insect eggs in the medicinal materials to prevent mildew and insect infestation during storage. In addition, since microwave heating makes the heated object itself become a heating element, which is called the overall heating method, it does not require the process of heat conduction, so it can achieve uniform heating in a short time. This feature allows materials with poor heat conductivity to be heated and dried in a short time, improves energy utilization, and can also make the size of the heating furnace smaller than conventional heating furnaces. Microwave drying equipment has become very popular in the market in recent years, and many microwave drying equipment manufacturers have invested in the research and development of microwave technology in an attempt to seize a place in the market.
