Air flow dryer is to dry the moisture from 12% to 6%-8% before the material (e.g. sawdust) is put into block extruding machine, if the material’s moisture is above 12%. The air flow drying machine productivity is adjustable as the requirements of customers.

Introduction

1. Air flow dryer applies the principle of instantaneous drying air to dry the moisture of raw materials.

2. Direct heating, fast drying, and high drying strength. Since the material is highly dispersed in the air stream, the entire surface of the particles is actively dried.

3. Short drying time, low energy consumption, and high thermal efficiency.

4. Air flow dryer has simple structure, small footprint, and easy to build and repair.

5. Air flow drying machine is equipped automatic speed-adjusting feeding machine, electric rolling screen, and discharging conveyor, which can automatically stop and feed according to the moisture content of the dried materials.

6. The moisture content of the dried materials are 8%-12%, so air flow dryer is the perfect equipment that preparing raw materials for pallet block production.

How Does Air Flow Dryer Work?

Air flow dryer is based on the principle of instantaneous drying of air flow. And the powder/chip/granular wood of wet shavings sawdust is continuously added to the drying pipe by the screw conveyor. In the transportation and dispersion of the high-speed hot air flow, the moisture in the wet material is evaporating to obtain the dried wood materials.

Air Flow Dryer Structure Feature

Air flow dryer consists of blower, heater, feeder, dryer, cyclone separator, pulse bag filter, induced fan, and supporting equipment.

1. The structure is compact and firm, with few wearing parts and convenient maintenance and inspection.

2. The entire process adopts air-solid co-current operation to reduce the final product outlet temperature.

3. Simple process, easy operation, stable operation, and wide application range, especially for heat-sensitive materials. Besides, the operating temperature is very low, only about 50 °C, even if longer dwell time will not damage to the material.

4. Reasonable distribution, and low requirement for material particle size distribution.

5. It is convenient to change the material type. When changing the dried materials, stopping to feed the wet materials, and the air blows for 15-30 minutes. Hence, it can save the complicated bed-clearing, improve the yield and reduce the labor intensity.

6. Only the minimal maintenance cost, due to few mechanic transmission components. The annual repair cost is no more than 2% of the investment cost.

7. Air flow drying machine is equipped with humidity-control temperature meter, which can directly see the moisture of the dried material.

8. Automatic ​​feeding machine adjusts the feeding speed according to the different raw materials moisture, so that the dryer achieves the best drying effect.
