The DW multi-layer belt dryer is a widely used continuous drying equipment in the industrial field, specifically designed for breathable materials such as sheets, strips, and granules, catering to large-scale production needs across various industries including chemical, food, pharmaceutical, and agricultural product processing.
The DW multi-layer belt dryer adopts a box-type multi-layer structure, with multiple stainless steel mesh belts arranged inside and driven by a transmission system for cyclic operation. During operation, the material is evenly spread on the topmost belt and gradually descends layer by layer as the belts move. Automatic material turning ensures uniform heating. The hot air employs a counterflow circulation process, where high-temperature, low-humidity air penetrates through the material layers from the bottom upward, facilitating thorough heat and mass exchange with the wet material. After moisture evaporation, the air carries the vapor away with exhaust gases, completing the entire drying process.
The DW multi-layer belt dryer features a compact structure and small footprint, allowing for adjustable belt speed, hot air temperature, and airflow based on material characteristics to accommodate various drying processes. With high automation, it operates continuously throughout the entire process, significantly reducing labor intensity. The equipment is equipped with a bottom discharge chute and a quick-open cleaning door for easy removal of residual powder, ensuring simple maintenance. Additionally, it boasts high thermal energy utilization efficiency, with most air capable of being recycled, offering energy-saving advantages. Particularly suitable for drying materials with high moisture content and low heat resistance, it serves as a key piece of equipment in industrial drying processes.
