 Why to choose  firewood kiln drying  ?

Our equipment have two functions

A:Only normally vacuum drying 

B:Depth wood carbonization funcation

high temperature depth carbonization
tank diagram
Stage 1: raise and dry stage by high temperature , with high temperature
steam to raise 100℃, at this time ,the moisture of the wood is closed to
zero ,the drying time of high temperature is up to original moisture of
wood ,and variety of trees ,and thickness of wood , if treated wood have
high moisture ,it should be put into Kiln drying.

Stage 2:heat treatment stage ,the heat treatment is under low
oxygen airtight furnace ,according to treatment requirement , after high
temperature dry ,when the temperature of furnace get 200 ℃ ,we can
begin to treat, the time of heat treatment is up to original moisture of
wood ,and variety of trees ,and thickness of wood

Stage 3: cool and moisture mediation treatment stage ,after heat treated
wood become cool within controlled condition ,at this time use spray
system to cool down the temperature ,then to process moisture mediation
treatment .Pay more attention at this time ,after heat treatment wood is in
high temperature stage , and have big temperature difference with
outside .it will make wood crack ,this treated time is related to variety of
trees and treated time

Technology:

dry in the drying kiln with normal temperature
 high temperature steam dry in the carbonization tank
 high temperature heat treatment in the carbonization tank
spray cooling

Noted :There is no any chemical within whole treatment process ,it won’t
produce any harmful material after treated ,after treated wood ,the
moisture will reduce down ,filber texture was
destroyed ,therefore ,Thermo-modified wood (carbonization wood )
with corrosion ,Non-defrmation ,Non-nature crack

Technology data:

Feature :

1.    Double safety protection device :we design double safety device ,manual safety ,and automatic safety interlock ,Only there is pressure inside the tank ,the worker cann’t open the door .

2.    Automatic set time function and light alarm  ,save worker’s time ,you can set any time in the control box ,once it finish ,it will stop work and alarm

3.    Quickly discharge chemical :10 minutes to discharge chemical ,improve treated time

4.    Perfect tightness :we use air filled style to seam the door and the system match automatic inlet and outlet air pneumatic valve, it can balance tank pressure well .

5.    High efficiency ,save energy ,once the equipment finish vacuum and pressure stage ,the pump will stop ,but whole tank still keep vacuum state

6.    Advanced open door method ,only one young girl can open the door easierly 

7. 2-3 days to finish one circle for some timbers .Less crack.Low moisture .

Saturation steam improve temperature efficiency ,less steam to us .Avoid the wood crack and bend during heating process
