Woodworking Machinery HF Heating Vacuum Oven For Lumber Drying

Main Features

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 .

6)Envirnoment friendly

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.

2.High frequency generator



 This is the core of this machine, all procedures and main technology are inside,including PLC,electric valve etc.

3.Cooling tower

This part is mainly used in hot weather, the main usage is to cool the internal temperature, guarantee the drying speed and quality. 

4.Timber cart

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.

5.Stainless condenser

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.

6.Pressure system

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.
