The drying method of traditional Chinese medicine slices is directly related to the quality of the slices. Previously, drying in a sun room could meet certification requirements and reduce costs. However, currently, the design of a few companies' sun rooms is not reasonable. Firstly, the small area cannot meet production requirements. The second reason is that the facilities of the solar room are not fully equipped, with only dust prevention functions and no supporting ventilation, dehumidification, floor frame and other devices, resulting in slow drying speed. Our company has designed a belt dryer that conforms to the characteristics of traditional Chinese medicine slices. The belt dryer equipment is used to dry the slices, which is not affected by climate and is more hygienic than natural drying. It can also shorten the drying time and produce in large quantities.
Overview of Traditional Chinese Medicine Slice Belt Dryer Equipment
The traditional Chinese medicine slice belt dryer is composed of a feeding system, a fabric distribution system, an air inlet filtration system, a heating and cooling system, a host, a transmission system, a bypass filtration system, a discharge system, an exhaust and dehumidification system, and a control system. During work, the material is fed from the feeding system to the fabric distribution system and added to the belt dryer. The material meets the throughflow hot air and cold air passing through the mesh belt for heat and mass transfer. The hot air is recycled to reduce energy consumption. After reaching a certain humidity, some of the moisture is forcibly removed, and the material is dried and cooled.
Characteristics of Traditional Chinese Medicine Slice Belt Dryer Equipment
1. The temperature of the hot air inlet is displayed and controlled through a ratio control valve, thereby controlling the inlet temperature within the set range.
2. The speed of the mesh belt is variable frequency adjustable, ensuring the residence time of the material and ensuring the quality of the discharge.
3. The frequency conversion of the transmission motor, mixing motor, and dehumidification fan is adjustable.
4. The bottom layer of the belt conveyor mesh belt is made into an inclined surface for material collection and cleaning.
5. After the equipment is manufactured, the transmission and conveying system is put into trial operation without any abnormal noise or jamming.
6. Install an ultrasonic level detector on the mixing silo to ensure a reasonable level of material, which is linked with the front conveyor line to make the production line smoother.
7. The doors on each part of the box are well insulated, 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 interior of the equipment.
Suitable materials for traditional Chinese medicine slice belt dryer
The drying machine for traditional Chinese medicine slices can dry most of the traditional Chinese medicine herbs, such as flakes and powders, through the temperature and speed of the equipment parameters.
