There are two types of medicinal herb dryers: mesh belt medicinal herb dryer and box type medicinal herb dryer. For small household use, customers can choose the appropriate model based on their own medicinal herb drying output.

By using a heat pump evaporator to absorb heat from the outside air or recover waste heat from the exhaust during the drying process, the energy is transferred to the drying room through a compressor. The hot air in the drying room is repeatedly circulated and heated to absorb moisture from the material, and then cooled and humidified by itself. Through the process of hot air dehumidification or condensation dehumidification, the water in the material is discharged and carried away, achieving continuous drying of the material.

Precautions for drying medicinal herbs with a drying machine:

1. Types and properties of medicinal herbs – Medicinal herbs include roots, stems, leaves, fruits, seeds, skins, etc. The appearance, size, thickness, weight, texture, composition, and other factors of medicinal herbs all affect the drying process.
2. Drying temperature – Depending on the different medicinal herbs, it is advisable to choose a higher drying temperature while ensuring the quality of drying. To accelerate the drying speed.
3. Humidity – the content of medicinal herbs with different humidity levels
4. The wind speed of the hot air medium is related to the drying speed, material form, and material characteristics of the hot air medium in the small household of the medicinal herb dryer.
5. The selection of drying speed and drying method – Drying should be controlled under certain technical parameters such as temperature, humidity, and wind speed. To ensure the preservation of pharmacological components of the material during the drying process.
6. Material placement method – stacking thickness, placement method affects drying speed. The stacking thickness should be reasonably controlled, and the heat exchange area and ventilation rate should be increased to accelerate the drying speed.
7. Mixing and drying of different varieties – In principle, when drying Chinese medicinal materials, a single variety should be used, and not enough varieties should be mixed together for drying.
8. Secondary drying – generally refers to the secondary drying of stored raw materials that have already been dried before processing medicinal herbs.

The working principle of microwave drying equipment for traditional Chinese medicine is based on the interaction between microwaves and materials. Microwave is an electromagnetic wave with strong penetrability. When microwave comes into contact with traditional Chinese medicine, the water molecules in the medicine absorb microwave energy and generate heat due to friction and collision between molecules. This heating method from the inside out enables Chinese medicinal materials to quickly heat up and evaporate moisture in a short period of time, thus achieving the purpose of drying.

Compared to traditional hot air drying methods, microwave drying equipment for traditional Chinese medicinal materials has significant advantages. Firstly, microwave drying has a fast speed, greatly shortening the drying cycle of traditional Chinese medicine. This is undoubtedly a huge advantage for Chinese medicinal materials that require rapid processing. Secondly, microwave drying can maintain the original color and quality of traditional Chinese medicinal materials. Due to the fact that microwave drying is carried out from the inside out, it can avoid problems such as discoloration and flavor change caused by overheating of the surface of traditional Chinese medicinal materials. In addition, microwave drying also has a sterilizing effect, which can sterilize Chinese medicinal materials while drying, further improving the hygiene quality of Chinese medicinal materials.

The application range of microwave drying equipment for traditional Chinese medicinal materials is wide, covering the processing of various traditional Chinese medicinal materials. For example, for Chinese medicinal materials with high moisture content such as ginseng and wolfberry, microwave drying can quickly reduce their moisture content, prevent mold and insect infestation. For traditional Chinese medicinal materials such as chrysanthemums and honeysuckle that need to maintain their color and aroma, microwave drying can preserve their original quality and efficacy. In addition, microwave drying can also be applied in the field of deep processing of Chinese medicinal materials, such as drying of Chinese medicinal material extracts and preparation of Chinese medicinal material powders.

With the continuous development of technology, microwave drying equipment for traditional Chinese medicine is also constantly innovating and improving. On the one hand, microwave drying equipment has a high degree of automation, which can achieve automatic control of the entire process of feeding, drying, sterilization, and discharging of Chinese medicinal materials. This not only improves the production efficiency of the equipment, but also reduces labor costs and operational difficulties. On the other hand, the intelligence level of microwave drying equipment is also constantly improving. By adopting a PLC intelligent control system, the drying degree and temperature distribution of Chinese medicinal materials can be monitored in real time, ensuring the drying effect and quality of Chinese medicinal materials.
