Environment Friendly Airflow Industrial Drying Equipment For Drying Sawdust

Equipment Introduction

Environmental friendly airflow industrial drying equipment is also called as hot air tube dryer, which

adopts instant drying principle. As hot air moves very fast, wet granula is scattered and driven by high-

speed hot air. It is suitable to dry wood powder, sawdust, rice husk, bamboo powder and bran, etc.,

light and low-density material. Based on technology of straight pipe air dryer, we develop variable

diameter air tube (pulse pipe), in order to increase thermal efficiency. Material goes into small-diameter

pipe at first. Meanwhile, air flows at high speed and so it accelerates material. When it comes into

bigger-diameter pipe, it stops accelerating. Because of material inertance, its speed is faster than air

speed. Therefore, its speed keeps decreasing because of airflow resistance. When material goes to

small-diameter pipe, it accelerates again. Material speed increases and decreases again and again,

thus heat exchange area and relative velocity are quite big. In this way, it increases thermal efficiency.

Dried material will be collected by cyclone dust collector, end gas will be exhausted into atmosphere by

induced draft fan.

Performance Characteristics

1. Short drying time, fast dewatering.

2. High thermal efficiency and without overheat.

3. High degree of automation, good quality dry product.

4. Simple structure, little space and cost down.

5. It makes use of sludge to produce valuable fertilizer, concrete aggregate, even fuel. That is why we

call it environmental friendly.
