　　Overview of DW series belt drying unit equipment:

The entire equipment is fully enclosed (for materials), consisting of five parts: feeding system, hot air system, discharging system, and dehumidification system. The feeding section ensures that the material is evenly dispersed on the mesh plate and transported to the drying section at a constant speed; The hot air system provides the necessary heat source for drying, delivering hot air at approximately 100 ℃ to the drying chamber; When the conveyor belt passes through, hot air passes through the material on the conveyor belt from top to bottom or from bottom to top, so that the material can be evenly dried and discharged from the discharge section.

1. The heating is steam heating (or natural gas), and steam heating uses a tubular fin radiator for heat exchange. The material is 304, and the temperature of each unit can be independently set and controlled.

2. The belt type host adopts an integral steel frame structure, and the inner and outer walls of the equipment are made of 304 brushed plates, with external wall insulation;

The mesh belt in contact with the material is made of stainless steel mesh belt, and the mesh plate blocking plate, chain, sprocket, track, circulating fan, and dehumidification fan are all made of stainless steel

3. The feeding method of the material is to use a bucket elevator to lift the material to the * layer swinging feeder, and the swinging feeder evenly distributes the material.

4. This belt type adopts a separate air circulation structure for the material layer, with most of the air being circulated and a small portion being used for dehumidification;
