The hopper dryer is a replacement product of the standard hot-air dryer. Based on the original function, the environmental protection factors are fully considered and improved. It can dry raw materials that are wet due to packaging, shipping, or recycling.

working principle

In the processing of raw materials, the hopper dryer blows a constant high-temperature air into the drying barrel through a drying fan. After baking the raw materials, the original moisture of the raw materials in the barrel is taken away to achieve the purpose of removing the moisture content of the raw materials. The air blown by the fan becomes high-temperature dry hot air after being heated by electric heating, and through the screen protector and the hole screen device, the hot air can be evenly dispersed in the raw materials in the drying barrel. Optional hot air recovery device, the blown air is filtered by the return air and enters the drying fan to form a closed circulation circuit, saving electricity.

Application range

The hopper dryer is the most effective and economical model for drying plastic raw materials. It can dry raw materials that are wet due to, packaging, transportation or recycling. The direct-coupled design is particularly suitable for direct installation on a plastic molding machine for drying, which is fast and space-saving. This up-blowing hot air dryer can provide a loading capacity of 12 ~ 1000 kg, which is divided into 13 types.

Features of hopper dryer

1. Adopt a high-performance hot-air diffusion device that evenly disperses hot air to maintain uniform drying temperature of plastics and increase drying efficiency.

2. The unique hot-air bending pipe design can avoid the accumulation of dust on the bottom of the electric heating pipe and cause combustion.

3. All the parts inside and inside the barrel are made of stainless steel.

4. The material barrel is separated from the bottom, which is convenient for cleaning and quick for changing materials.

5. A proportional deviation indicating temperature controller is adopted to accurately control the temperature.

6. There are double overheating protection devices, which can reduce accidents caused by human or mechanical failure.

7. Various models can provide preheating timing devices, microcomputer control, and double-layer insulation barrel selection.

8. Transparent window magnet base.
