Difference between microwave drying equipment and traditional drying equipment

What are the advantages of microwave wood dryer compared with traditional wood drying?

Fast microwave drying speed: traditional drying needs to fill a kiln and then dry, and the drying cycle is long; Microwave drying can be used and dried immediately, and the drying amount can be flexibly controlled.

Microwave drying is uniform: the traditional drying method starts from the surface of the wood. There is a heat conduction process, and it is easy to see that the outer coke does not dry inside. Often, after a period of time, the water inside will permeate outward, and the products produced will either expand or shrink; Microwave drying is to pull out moisture from the inside out, which effectively solves the problem of difficult drying in the process of traditional drying method. Microwave drying can penetrate the interior of wood, kill insect eggs, prevent moths and molds, and prolong the storage period.

If microwave drying is used, will the wood deform and crack?

In case of improper operation, cracking and deformation may occur. In addition, if the material before drying has cracks, the cracks will become larger during drying. How can this situation be stopped? We suggest drying the wood with different thickness and moisture content separately, which can greatly avoid deformation and cracking.

Can such a fast speed really dry wood?

The answer is yes, but because of the high density of wood, such as rosewood, ebony, chicken wing wood, sour branch wood, Brazil flower pear and so on, it is difficult to pull out water from the inside, and if forced to dry quickly, it may lead to wood deformation and cracking. Take mahogany as an example. Mahogany has a high oil content. If it is dried too quickly, it is easy to pull the oil out to the surface. In this process, the activity of the wood will be destroyed, resulting in the water inside being unable to be separated and the water on the surface being unable to soak. Therefore, the drying time is recommended to be carried out slowly, but not more than 10 days at most.

Can wood of different thickness be mixed and dried?

It is recommended to dry them separately. Microwave heating is completely different from the traditional heating method. Microwave makes the material itself become a heater. The more water the material contains, the easier it is to dry. Therefore, wood with different specifications and relatively large water content should not be dried at the same time.
