The principle of paraformaldehyde dryer is analyzed by manufacturers.

Generally, two stages of belt drier are used in series, which is divided into feeding section and discharging section. Due to the high moisture content and poor permeability of the material in the feed section, the material thickness is thin, the running speed is fast, and the drying temperature is high. According to the nature of materials, the temperature is generally around 120. As most of the moisture in the material is removed from the feed section, the water content of the material entering the discharge section is less than that of the material, and the material is well ventilated. Moreover, the water content of the material is mainly internal moisture, which needs a certain drying time. Therefore, the mesh Belt should be placed in a slower position and the material layer is thickened. According to the nature of the material, the drying temperature should not exceed the temperature of the material. The temperature in the dryer box has a temperature measuring point, which controls the amount of steam through the solenoid valve, so as to achieve the purpose of controlling the temperature. Through two stages of drying, the performance of belt drier is better played. After drying, the water content is uniform, color, intensity, luster and other dry paraformaldehyde equipment manufacturers Drying and drying products quality has been greatly improved.

The manufacturers of polyformaldehyde equipment introduce the characteristics of the dryer.

1, can adjust the air volume, heating temperature, material residence time and feeding speed to achieve excellent drying effect.

2. The equipment is flexible, and the net belt washing system and material cooling system can be used.

3, most of the air recycling, highly energy saving.

4. The unique air distribution device makes the distribution of hot air more uniform and ensures the consistency of product quality.

5. Heat sources can be supplied by steam, heat conducting oil, electricity or coal fired (oil) hot blast furnaces.
