Nowadays microwave technology is widely used in various fields so does in Chinese herb medicine. Microwave drying appropriately covers the shortage of traditional drying methods and also shows its prominent features and fits the environmental protection theme.
Superiorities of Microwave Herb Drying over Hot Oven Drying
1. Drying evenly and thoroughly within a short time
Microwave has strong penetrability and can directly penetrate into the inside of herbs and generate heat, thus the herbal medicine simultaneously absorbs the microwave energy both interior and exterior so they can be dried evenly and thoroughly within a very short time.
2. Selective heating, keep the original active ingredients, has good drying and sterilizing effects
The substances’ ability to absorb microwaves is different. Water has a stronger ability to absorb microwaves than other materials so the herbs can be dried by low temperature without destroying its structure and active ingredients. During the drying process, it can also be sterilized so the herb’s shelf life is largely extended.
3. Energy-saving and productive cost saving
The microwave heat is directly absorbed by the herb medicine without heat loss. So the thermal efficiency is high and can save energy and production cost.
4. Environmental Friendly
It uses electricity and does not produce harmful gas or liquid and has no noise. So it is an eco-friendly drying technology.
5. Easy operation and high efficiency
Industrial microwave drying machines can continuously dry herb medicine so the efficiency is increased. In addition, it adopts the automatic PLC control system, easy to operate and greatly improves the working conditions.
Besides, the microwave drying equipment can finish drying and sterilization processes simultaneously without other ancillary equipments, then the cost is reduced to some extent.
