The drying method of Chinese herbal decoction pieces is directly related to the quality of the decoction pieces. In the past, using solar house drying not only met the certification requirements but also reduced costs. However, the solar house design of a few enterprises is unreasonable. First, the small area cannot meet the production requirements. The second is that the sun room facilities are not fully equipped, only dust-proof function, without supporting ventilation, dehumidification, floor and other devices, the drying speed is slow. According to the characteristics of Chinese herbal medicines, our company has designed a belt dryer suitable for Chinese herbal medicines. Using the dryer equipment to dry the herbal medicines, it is not affected by the climate, it is hygienic than natural drying, and can shorten the drying time, and can be mass-produced. .
Overview of Belt Dryer Equipment for Chinese Medicine Pieces
Chinese medicine decoction belt dryer is composed of feed system, cloth system, air filtration system, heating and cooling system, host, transmission system, bypass filtration system, discharge system, exhaust system, control system, etc. When working, the feeding system feeds the material to the distribution system, and the materials are added to the belt dryer. The materials meet the through-flow hot air and cold air passing through the mesh belt to conduct heat and mass transfer. The hot air circulation makes the energy consumption more Low, after reaching a certain humidity, part of the forced dehumidification takes away the moisture, and the material is completely dried and cooled.
The characteristics of the belt dryer of Chinese herbal medicine pieces
1. The temperature of the hot air inlet is displayed and controlled by the ratio adjustment valve, so that the temperature of the air inlet is controlled within the set range.
2. The frequency of the mesh belt can be adjusted by frequency conversion, which ensures the residence time of the materials and the quality of the materials.
3. The frequency conversion of the transmission motor, stirring motor and humidity exhaust fan is adjustable.
4. The bottom of the belt with the machine is made into an inclined surface to facilitate material collection and cleaning.
5. After the equipment is completed, the transmission system will be put into trial operation without abnormal noise and jamming.
6. An ultrasonic level detector is installed on the mixing silo to ensure a reasonable level, and it is linked with the front conveyor line to make the production line smoother.
7. The doors on each part of the cabinet are well insulated, well sealed, and easy to open and close.
8. There are cleaning and maintenance doors on both sides of each unit, which can directly flush the inside of the equipment.
Applicable materials for Chinese medicine decoction belt dryer
The Chinese medicine decoction dryer can dry most of the Chinese medicinal materials through the temperature and speed of the equipment parameters, and almost all Chinese medicinal materials such as flakes and powders can be dried.
