Working Principle

This drying machine is one kinds of airstream dryer. The hot air enters into the bottom of the dryer machine in tangent direction and forms a powerful rotating wind with the driving of the stirrer. The paste-like materials enter into the dryer through the vane feeder and are dispersed by the striking, friction and shearing force produced by powerful stirring of the high-speed rotary stirring paddle,  The lump materials will soon be smashed heated and dried after contacting the hot air fully . The dried materials after dehydration will go up with the hot air with its big particles trapped by the grading ring. Small particles will be discharged out of the drying machine from  center ring and then collected in the cyclonic separator and dust collector. The not-fully-dried or big pieces of materials will be slammed to the wall by centrifugal force and smashed again for drying after they fall down to the bottom.

Characteristics

Airstream dryer integrates rotary flow, fluidization, spouting and stage reduction technologies. The equipment is compact and small in size, high in productivity .It is "a small equipment for large production" which can perform continuous production.

It has high drying strength, low energy consumption and high heat efficiency.

With short stay for materials and quality finished products, the machine can be used for drying heat sensitive materials.

For the negative pressure or the micro-negative pressure operations, the machine is good for its tightness and high efficiency so as to eliminate the environmental pollution.

Technical Parameters

Note:

1. Water evaporation refers to the amount of moisture evaporated per hour when the air inlet temperature is 180℃ and the air outlet temperature is 80℃.

2. Besides the models above, the dryers can be specially designed upon request.

3. The installed capacities above are standard sets. The power will vary with different materials.
