High frequency vacuum wood dryer

Brief introduction of high frequency vacuum wood dryer

High frequency vacuum wood dryer is also named as rotary wood sawdust dryer, wood

vacuum dryer, sawdust rotary dryer, wood drying drum, etc. which can dispose a large

capacity granules material in a short time. Because of high frequency vacuum wood dryer’s

safe and reliable operation, big operational flexibility, large capacity of disposal and low

consumption,it is widely applied in building materials, metallurgy, food, chemical, coal,

medical, mining etc industries.

High frequency vacuum wood dryer is used to dry up wood sawdust/wood chips/wood

shavings, etc. whose humidity around 60% till their' humidity around 1.5%-5%. The innner

hot air temperature can be around 700 ℃, this makes wood chips/wood shavings/wood

sadust, etc. easily to be dried up in a short time, so our wood vacuum dryer's production

capacity is very large, it can be 1-20 tons per hour. By the way, final humidity is customized

by adjusting its rotational speed and its moving speed. (high frequency vacuum wood dryer)

The working principle of high frequency vacuum wood dryer

During the movement in high frequency vacuum wood dryer, the material gets the heating

directly/indirectly, and then is dried. Later the dried material is transferred by the belt conveyor

/spiral conveyer at the discharging opening.There are lifting boards on the inside wall, which

lifts and scatters the material to make the contact surface bigger between the material and the

heat carrier. This can promote the drying rate and push the material forward. Heat carrier is

usually hot air or flue gas. After go through the dryer,the substances containing in the heat

carrier usually need to be collected by cyclone dust collector. If the air dust content need to

be reduced further, bag filter or wet dust remover shall be used.(high frequency vacuum wood

Structure of high frequency vacuum wood dryer

High frequency vacuum wood dryer consists of seven parts: they are feeding hopper, heat

source, rotary drum, lifting board, draught fan, unloader. (high frequency vacuum wood dryer)

Features of high frequency vacuum wood dryer

1. Large production capability, continuous operation

2. Simple structure, convenient operation

3. Low malfunction, low maintenance cost.

4. Wide scope of application, can be used to dry the granular materials, favorable for those

materials with the big adhesion.

5. Great operating flexibility, the output of the products allows a larger fluctuation range, not

influencing the quality of the products.

6. High thermal efficiency(≥ 60%)

7. Medium temperature in outlets(about700 degree)

8. Alloy steel plate or stainless lifting plate

9. Guaranteed drying effect (≤ 5% after drying)

10. Final wood sawdust's humidity can be adjusted by adjusting its speed.

11. Far-ranging raw material: such as wood sawdust, wet sand, clay, coal, etc.(high frequency
