Introduction

Flash dryer ( airflow type  dryer) is a pneumatic drying system used to dry products requiring the removal of free moisture. This equipment is using the heat from the air steam.

Typical Applications

Ideal for removal of moisture from free flowing materials which is light and small like sawdust, rice hull, milled stalks etc.; suitable for small production scales below 700kgs per hour.

Comparing with rotary dryer, the flash one has the advantages of low energy consumption and low cost. It is in simple design but have good effect as well.

Working Principle 

Wet material is input into the hopper. The dryer is equipped with two fuel boilers, inlet, steel pipe, exhaust blower (fan), air lock and cyclone. Wet materials are input into the hopper. The fuel boiler generates hot air which mixes with wet materials and then is sucked into the pipes by the exhaust blower (fan) quickly. And then hot air is flowing and going though the curving pipes and buffer (drying chamber) of dryer, thus wet materials is finished to dry, and the dried materials are discharged from the outlet with air lock.

Heat Stove: it's made up of armor plate,firebricks,and stove chain. It's used to supply the heat to the drier.

Channel Tube:It's the passway to transport the material to the rotary body and the impulse jar.

Impulse jar and fuction tube: Used to mix the material with heat thoroughly to reduce the water.

Fan is made up of fan wheel made of the 400 model armor plate,4kw fan. It's used to supply power to transport material into seperator.

Cautions of operation the dryer

1.The speed of the charging material mainly base on the primary moisture. The charging speed is high when moistuer is low. When the moisture is high the charging speed is low.

2.Every 10 days add lubricating oil to the bearing.

3.Check the tube often, remove the ash blocking the dust removal hole

4.To make sure the material is the sawdust size less than 5*5mm. Commonly before drying the material need separated by the screen to remove big size material.

5.If the impulse jar is blocked open the hole underside to lease the block.

6.The high temparture is prohibited.

7.Discharging material with high temperature is prohibited in case of the fire disaster.

8.Before the production please check if the electrocircuit is correct
