The advantage and principle of chain plate Microwave Wood Drying Equipment

Since the reform and opening up,China’s wood drying industry has been rapid development, has become a perfect industrial system.Especially in recent years, with the gradual increase of China’s wood consumption, the wood drying market is more prosperous, which brings a good opportunity for the rapid development of China’s wood drying industry.

The advantage and principle of chain plate Microwave Wood Drying Equipment

The Microwave hot air dehydrating drying machine LD1504 has the following advantages:

1.Chain plate microwave wood drying equipment has fast drying speed.

When Chain plate microwave wood dryer drying wood,because heat is not coming from the outside of wood,friction between water molecules and wood directly generate heat inside the wood, it also known as volume heating.

This volumetric heating causes the heat transfer of the dried wood to occur almost simultaneously along the entire thickness, and the time required for heat transfer is independent of the thickness of the wood.

The moisture inside the wood quickly vaporizes, creating outward diffusion pressure, and at the same time, there is heat loss and water evaporation on the wood surface.In fact, the internal temperature of wood is higher than the surface temperature, so the microwave drying temperature gradient and moisture content gradient direction is the same, greatly accelerating the movement of water speed.

2.Chain plate microwave wood drying machine has good drying quality.

Due to increased permeability during wood drying in the chain plate microwave wood drying production line,During the drying process, the heating is uniform, and the water in the wood is discharged from the inside out at the same time, so that the expansion and contraction coefficient of the wood are basically the same.The defect such as deform, craze that can avoid lumber to appear in drying process to the largest extent so, and dry even.

3.Microwave wood drying equipment can maintain the original color of wood.

The higher the temperature, the longer the action time, the higher the moisture content, the faster the wood discoloration.Compared with conventional drying, the microwave drying cycle of wood should be shortened by tens to hundreds of times.In addition, each heating process from low temperature to high temperature,the duration of stay at high temperature is shorter.So the chain plate microwave wood drying equipment almost does not change the original color of wood.

4.Chain plate microwave wood drying equipment can directly dry wood semi-finished products.

The biggest characteristic of wood microwave drying equipment is that it can dry semi-finished products of wood products.Microwave drying molding wood directly, no deformation, no cracking, no damage to the wood, and occupies a small area of the site, with a certain degree of insecticidal function.

Main methods of modern drying technology:

1.Air pre-drying technology utilizing natural energy, solar drying technology, and drying technology combining solar energy and other drying technologies;

2.Surplus hot water drying technology of power plant and boiler exhaust drying technology using waste energy;

3.Waste combustion drying technology；

4.Intelligent drying technology, that is to use the intelligent control technology of wood drying to achieve intelligent and efficient drying of different wood;

5.Efficient combination of different drying methods;

6.Wood pretreatment and drying technology enhances wood moisture conductivity through modern biological technology, mechanical technology and chemical treatment technology.Finally it can improve wood drying performance.

Principles of chain plate microwave wood drying equipment produced by Leader Microwave Equipment Company:

The principle of chain plate microwave wood drying equipment for wood drying using wet wood as the dielectric, water molecule polarization in wood is caused by the action of microwave electromagnetic field.Meanwhile, due to the frequent alternations of electromagnetic fields, water molecules frequently swing at high speed and generate heat by friction, thus heating the dry wood.

As a kind of special heat conduction way,microwave technology converts electromagnetic energy into heat energy.It not only has a wide range of uses in food heating, insecticidal sterilization, dry preservation and other aspects,but also develops to the application of catalytic chemical reaction and microwave treatment of new materials.A variety of microwave agricultural and sideline products, leisure food sterilization equipment also mushroomed.

With the continuous in-depth development and improvement of microwave drying technology in wood processing,it will make the wood processing more safe, energy-saving, efficient and environmental protection, so as to drive the economic growth of China’s wood industry and promote the rapid development of environment-friendly society.
