New Technology Vacuum Chamber High Frequency Hardwood Drying Equipment
It is a newest generation wood drying equipment and a result of design combining high frequency medium heating technology and vacuum cryogenic dehydration technology, greatly reduced drying time. This equipment adopts PLC programming control, drying chamber equipped with 80 mm thick thermal insulating layer and inside & outside two sets stainless steel condensation system, it is more convenient to choose lumber drying procedure and applicable for drying all kinds of wood. The Main control valve adopts pneumatic valve technology, this technology have advantages like steady, long serve life and low failure rate. The main advantage of our wood drying equipment: short drying cycle, super quality, cost effective and Eco-friendly.
SPECIFICATIONS FOR HF VACUUM WOOD DRYING MACHINE
Max Length of Wood
1) Fast speed and high efficiency
When HF starts,the molecules in the dielectric material will be polarized in very short time and heated.HF power only heat polar molecules.It will not heat dielectric material.HF heating is 3-5 times faster than hot steam.So it can save the power and improve the efficiency.
2) Uniform heating
High frequency heating is dielectric heating.It forms electric filed with positive and negative pole.HF power can penetrate material deeply.The waster or glue molecules in the material will get heated themselves by friction among molecules.In this way,they get heated from the core material,much more uniformly.
3) Good applicability
High frequency heating can heat kinds of thickness material,such as 2-3mm venner surface lamination,1000mm thick engineered wood gluing.And different frquency can meet different material requirement.13.56MHZ is suitable for PVC heating and gluing 27.12MHZ is good for line production .
4) Strong controllability
High frequency heating is easy control and suitable for automatic production.Take HF edge gluer for example,HF can equip well with hydraulic system,electrical system can finish the whole process together.It can also well cooperate with last procedure.
5) No damage of wood
In the vacuum environment, moisture can evaporate at lower temperatures ,so vacuum cryogenic dehydration technology avoid high temperature to damage wood .
HF heating doesn't need boiler.There is no dust,no fog,no pollution.DAXIN's products accord with national standard of radiation.
1.High strength steel structural oven body.
This makes the whole machine stronger and more leak-proof of vacuum.
2.High frequency generator
This is the core of this machine, all procedures and main technology are inside,including PLC,electric valve etc.
This part is mainly used in hot weather, the main usage is to cool the internal temperature, guarantee the drying speed and quality.
We have both full-auto feeding mode and manual feeding model, but the full-auto is only used on 8/10/12/15cbm models, because the smaller doesn’t need this, the loading quantity is enough to be push into the oven by workers.
This parts are also to reduce the internal temperature when drying, it will let the steam change into water droplet, to guarantee the drying speed and quality.
We have both hydraulic and pneumatic, that means common oil pressure system and air pressure system, they are to prevent the wood becoming bend and crack.
7.Perforated aluminum plate ,copper strip and wooden bar.
Aluminum plade and copper form electric field, to speed up the electronic movement and enhance the heating rate.
These two parts are to separate wood to dissipating heat quickly, guarantee the drying speed.
Comparative With Microwave Heating
High frequency vacuum
The internal and external heating
Outside high,inside low temperature
Can be high to low
Maybe some damage
Microwave vacuum wavelength 600-900 MHz, and 600-700 MHz can be used, the rest is radiation. Usually below 30 MHz , no provisions of the state.
Moisture reduced to 6.6%.
Dehydration up to 243kg one day
