The microwave drying equipment places the wood to be dried in a microwave electromagnetic field. Under the action of the microwave electromagnetic field, the water molecules in the wood are polarized, and the high frequency of the water molecules in the wood is rapidly oscillated by the frequent alternating electromagnetic fields, so that the electromagnetic field The electrical energy is converted into heat between the water molecules, which heats the wood.
Because microwave has superior penetrating ability, independent of the thickness of wood, the intensity of water in wood increases with the increase of moisture content of wood, while the moisture content of wood under natural conditions increases gradually from the inside to the outside. Large, this makes the heat inside the microwave drying wood larger than the outside, which is basically consistent with the gradient of the moisture content of the wood itself, further speeding up the migration of moisture inside the wood to the surface of the wood.
