Traditionally, the processing method of boxing ginseng is mainly sun-dried. Although the way of sun drying is simple, there are some problems. First of all, it is greatly affected by the weather, easy to dry on sunny days, difficult to dry on rainy days, and easy to be polluted by the external environment. Secondly, the speed of sun drying is slow and the time is long, which is easy to cause problems such as mildew and deterioration, which affects the quality of medicinal materials.
In contrast, there are clear advantages to using a heat pump dryer for drying. First of all, the heat pump dryer can be dried in a controlled environment, avoiding the problem of weather and external environmental pollution. Secondly, the heat pump dryer has the characteristics of fast drying speed and high efficiency, which can greatly shorten the drying time, reduce the risk of mildew and deterioration, and help maintain the high quality of medicinal materials.
In general, the heat pump dryer has obvious advantages in the drying process of boxing ginseng, which helps to improve the quality and medicinal value of boxing ginseng, and is worthy of being widely promoted and applied in boxing ginseng.
