Fully automatic wood drying equipment

1、 【 Fully Automatic Wood Drying Equipment 】 Purpose and Introduction:
Fully automatic wood drying equipment is a new technology widely used in industries such as wood, furniture, wooden flooring, plywood, and artificial boards for wood drying. Due to deformation, cracking, mold, and other reasons during conventional drying, a large amount of waste is caused; Microwave drying machines have a series of advantages such as uniform heating, fast drying speed, no deformation, no cracking, anti moth and anti mold properties, good product quality, and are conducive to continuous and automated production.
The unique feature of microwave drying of wood is that the heat is not transmitted from the surface of the object, but is directly heated by the absorption of moisture and the wood itself through the interior of the material by microwaves. Due to the evaporation of surface moisture, the internal temperature of the material is higher than the surface temperature. This creates an outward pressure difference inside the material, accelerating the surface migration of moisture. Microwave drying of wood is a process in which wet wood is used as a dielectric. Under the action of a microwave electromagnetic field, water molecules in the wet wood undergo hydration. Due to the frequent alternation of the electromagnetic field, the water molecules undergo vigorous movement, generating heat through friction and drying the wood. Microwaves act directly inside the dried wood, which is called "heat transfer". The time required for "heat transfer" is not related to the thickness of the wood, but to the electric field strength, microwave frequency, and dielectric properties of the wood. When microwaves act on wood, when the temperature inside the wood is above 100 ℃, excessive water vapor pressure is generated in the wood, accelerating the movement of water molecules. So the speed of microwave drying of wood is much higher than that of convection drying (natural drying, steam drying, infrared drying, etc.).
Microwave drying of wood generally uses a microwave frequency of 915 MHz with a penetration depth of 80mm, while a microwave frequency of 2450 MHz with a penetration depth of 50mm can fully meet the requirements of general processed finished wood. For different yield sizes and drying requirements, different forms of microwave wood drying equipment can be selected; For various types of wood with different properties, it is necessary to select appropriate microwave heating speeds to achieve optimal process conditions and obtain good benefits.

2、 Advantages of fully automatic wood drying equipment:
1. Fast drying speed and high efficiency. According to data, the drying speed of 25-50mm pine boards is 20-30 times faster than the commonly used convection drying speed. The moisture content of wood can be reduced from 30% to 12% in just 20-45 minutes.
2. Dry wood is uniform, non deformed, and non cracking. Due to the simultaneous action of microwaves on the inner and outer parts of wood, heat is evenly generated. Therefore, wood treated with microwaves dries evenly, improves product quality, prevents surface hardening, enhances toughness, ensures no cracking, deformation, discoloration, and can correct bending.
3. Anti moth, anti mold, and extended shelf life. Microwave drying of wood can penetrate the interior of the wood and quickly kill the parasitic insect eggs in the wood, achieving the effects of preventing moth and mold, and extending the shelf life.
4. Energy saving. Using far-infrared and steam energy for wood drying has an energy utilization rate of less than 50%, while using microwave as energy can achieve a utilization rate of over 75%, reducing energy consumption by more than 25% compared to far-infrared and steam drying.
5. Easy to operate and labor-saving. By utilizing the principle of microwave instantaneous switching, it is easy to operate, manage, reduce labor intensity, and save manpower.
6. Safety, hygiene, and environmental protection. The fully automatic wood drying equipment is noise free and does not produce any "three wastes" problems.
