Belt dryer for traditional Chinese medicine decoction piecesIt is a continuous drying equipment designed specifically for drying traditional Chinese medicine decoction pieces, widely used in the Chinese herbal medicine processing industry. This device continuously transports materials through a conveyor belt to achieve efficient and uniform drying processes, especially suitable for sheet and granular Chinese medicinal materials with good breathability. Its working principle is based on the hot air circulation system, where materials are evenly laid on the mesh belt by the feeding device and enter the drying zone as the mesh belt moves. Hot air or steam passes through the material layer from bottom to top or from top to bottom, increasing the contact area and promoting water evaporation. The dried material continues to move to the discharge port under the drive of the mesh belt, completing the entire drying process. The equipment adopts a multi unit design, and the temperature of each unit can be independently adjusted to achieve precise temperature control and meet the needs of different drying stages.

　　Belt dryer for traditional Chinese medicine decoction piecesRegular maintenance:

1. Filter system maintenance:

Regularly clean or replace the filters of the intake air filtration system and bypass filtration system. Generally, the initial efficiency filter is cleaned once a month, the medium efficiency filter is replaced once a quarter, and the high-efficiency filter is replaced once a year to ensure the cleanliness of the intake air.

Check the sealing of the filter and replace the sealing gasket in a timely manner if it is damaged to prevent air leakage.

2. Maintenance of heating and cooling system:

Regularly clean the finned heat exchanger and other components of the heating and cooling system, remove surface dust and dirt, and ensure heat exchange efficiency.

Check for leaks in heating tubes, cooling tubes, etc. If there are leaks, they should be repaired or replaced in a timely manner.

3. Maintenance of transmission system:

Regularly adjust the tension of the transmission chain to ensure that the tension of the chain is moderate, avoiding excessive looseness or tightness that affects the transmission effect and equipment life.

Check the wear of the sprocket and replace it promptly if there is severe wear.

4. Mesh belt maintenance:

Regularly check the wear of the conveyor belt. If there are any problems such as damage, deformation, or deviation, the belt should be repaired or replaced in a timely manner.

Correct the mesh belt to ensure smooth operation and no deviation.

5. Equipment calibration:

Regularly calibrate temperature sensors, humidity sensors, pressure sensors, and other detection components to ensure their measurement accuracy is accurate and reliable.

Check whether the various parameter settings of the control system are correct, and adjust them in a timely manner if there are deviations.
