sawdust dryers are specialized equipment designed and manufactured specifically for drying materials such as wood chips, sawdust, wood flour, and wood flakes. They feature high drying capacity, significant energy savings, and low maintenance.
Working Principle of sawdust dryers
The Shengwuz dryer primarily utilizes the principle of heat exchange. Wet wood chips come into full contact with hot airflow through the dryer's structure, achieving evaporation and dehydration under high temperature. Under the action of the lifting plates in the inner layer, the wet wood chips undergo initial heat exchange and spirally move to the other end of the inner layer, entering the middle layer. Here, counter-current drying occurs. The material is continuously and repeatedly lifted in the middle layer, moving in a two-steps-forward-one-step-back pattern. In the middle layer, the material fully absorbs heat from both the inner and middle drums, achieving an ideal dry state. The material moves to the other end of the middle layer and falls into the outer layer. Inside the outer drum, the material travels in a rectangular multi-loop pattern. Material that has reached the desired dryness level is quickly discharged from the drum under the action of hot air, while wet material that has not reached the desired dryness level cannot move quickly due to its own weight. The material undergoes thorough drying within these rectangular lifting plates, thus completing the drying process.
Sawdust Dryers Performance Characteristics
1. Automatic control system ensures stable drying performance and automatically removes impurities, preventing them from entering subsequent processes.
2. Low energy consumption and low emissions, resulting in low investment costs.
3. The thermal efficiency of the dryer drum's insulation is increased to over 70%.
4. Tail-end drive ensures smoother and more reliable transmission; completely eliminating the problem of slippage during roller rotation that affects production.
5. Optimized structure, small footprint, equipped with a new energy-saving hot air furnace, controllable thermal performance, simple operation, and a reduction in coal consumption of approximately 60%.
6. Upgraded material lifting combination distribution effectively controls drying time and improves drying quality.
7. The low exhaust gas temperature extends the service life of the dust removal equipment, allowing for continuous production in the next process.
