What is the reason why the dehumidifying dryer can not dry the material normally?

At present, with the extensive use of engineering plastics, dehumidifying dryers have gradually replaced traditional hot air dryers and are widely used in industrial production. The use of the dehumidifying dryer can be divided into a single type and a centralized type, and the single type dehumidifying dryer usually includes a drying machine main body, a dehumidifying drying machine drying barrel, and a suction machine. The single-machine type is suitable for a small variety of drying, which has the advantages of good drying efficiency and convenient and quick refueling.

The reasons why the dehumidifying dryer can not dry the material normally are as follows:

1. The waste heat flue gas with a temperature less than 350 °C can not be used as a heat source for drying materials.

2. The phenomenon that the particle size of the material becomes larger during the drying process cannot be solved, which greatly affects the material effect.

3. There are widespread problems such as large loss of heat loss, low thermal efficiency, high coal consumption, difficulty in controlling the moisture of the discharge, and low relative production.

4. The dehumidification dryer does not use the automatic microcomputer detection and control system, and can not accurately detect and control the materials, wind, coal, etc. in time, resulting in the drying system not being able to play.

5, can not adapt to the drying of materials containing crystal water, can not adapt to the drying of high moisture materials.
