lanyu new technology industrial hot airflow dryer in factory price

It issuitable for drying sensitive material like sawdust, rice hull, milled wheat straw, milled cotton/ corn stalks and so on.

It is made up of heat stove, tube, impulse jar, function tube, fan, and cyclone separator;

The Airflow Sawdust Dryer can reduce the humidity of wood materials below 12%;

It is professionally designed for drying different kinds of wood sawdust.

It has advantages of low cost, low consumption, easy maintainace.

In addition, the round places of pipes can be changed to any angle which can save space and solve plant dimension limitation.

Operation Principle:                                                                                                             

The whole system consists of fan blower, motor engine, fuel boiler, steel pipe, cyclone and air lock.

In this system, wet material is input into hopper by screw feeder.

Fuel furnace produces large volume of hot air.

The hot air is driven into steel pipes, mixed with wet sawdust and moved through curving pipes and drying chamber by the power of fan blower.

Fast moving hot air sustains and is mixed with raw material sent by spiral feeder in the suspending state through the steel pipe; moisture evaporates as the material traverses along the steel pipe and is rendered dry at the discharge end. Humid air is continuously exhausted, thus the material is dried.

2. Working principle:

The whole system consists of fan blower, motor engine, fuel boiler, steel pipe, cyclone and air lock.

a.In this system, wet material is input into hopper by screw feeder. Fuel furnace produces large volume of hot air.

b.The hot air is driven into steel pipes, mixed with wet sawdust and moved through curving pipes and drying chamber by the power of fan blower.

c.Fast moving hot air sustains and is mixed with raw material sent by spiral feeder in the suspending state through the steel pipe;

moisture evaporates as the material traverses along the steel pipe and is rendered dry at the discharge end. Humid air is continuously exhausted, thus the material is dried.

3.characteristic:

1.The air is heated to about 180-300 °C through the heater and enters the rotary flash dryer. The wet material is fed into the screw feeding mechanism by the conveying device, and the screw feeder can be steplessly regulated.

2.Since the material is micronized by centrifugation, shearing, collision and friction, it is highly dispersed, and the relative velocity between the solid and gas phases is large, which enhances mass transfer heat transfer and makes the machine have high production intensity.

3. The dry gas enters the bottom of the dryer, which produces a strong swirling airflow, which produces a strong scouring effect on the material on the wall to eliminate the sticking phenomenon.

4. In the high temperature zone at the bottom of the dryer, the heat sensitive material is not in direct contact with the hot surface, and a special cooling device is installed to solve the problem of coking discoloration of the heat sensitive material.

5. Due to the high circumferential air velocity in the drying chamber, the material residence time is short, achieving high efficiency, fast, small equipment,

6.The top of the drying chamber is equipped with a ceramic ring and a swirling sheet to control the particle size and humidity of the outlet material to meet the final moisture and particle size requirements of different materials

7.Reduce the chance of material contact with air, avoid pollution or oxidative deterioration
