Compared with the box type and vacuum microwave drying equipment, the tunnel type microwave drying equipment has the main advantages of continuous drying, large production and low labor intensity. Compared with the traditional equipment has the advantages of high efficiency, low enerLD consumption, the uniform heating, the drying speed is fast, the thermal inertia, the safety and environmental protection, the advantages of simple operation, easy to control etc..

Microwave sterilization equipment of wood drying focus ten years is applied to drying, ripening and sterilization of black Cereals, soybeans, mung beans, corn, wheat skin, buckwheat, oatmeal, soybeans and peanuts.Drying sterilization seafood seasoning, sterilization, drying, puffing Tenebrio; rose, tea and other tea flower.Conventional thermo - thermal sterilization starts from the surface of the material, but there is an internal and external temperature difference through the heat conduction to the interior. In order to maintain the food flavor, shorten the processing time.

Often the food inside does not reach enough temperature to affect the germicidal effect. Due to the penetration of microwave Ken, when the food is treated as a whole, the surface and the interior are simultaneously affected, so disinfection and sterilization are even and complete.

An overview of the
Tunnel type wood microwave drying machine is a new technoloLD, widely used in wood, furniture, wood flooring, plywood, particle board, and other industries of wood drying.Because in the conventional drying, due to out of shape, craze, mildew and other causes a large amount of waste;And microwave drying machine has uniform heating, fast drying speed, contorts, cracking, moth-proofing mouldproof, products of good quality and is conducive to continuous and automatic production and a series of advantages.Wood microwave drying characteristics of different heat is not the incoming object appearance, but the microwave through the material inside is absorbed moisture and lumber itself contains direct heating.Due to the material's surface water evaporation, therefore, the internal temperature of the material above the surface.Make the outward pressure difference is formed within the material, speed up the surface of the water migration.Microwave drying of wood is wet wood as the dielectric, under the role of microwave electromagnetic field, cause the polarization of wet wood water molecules, due to the frequent alternating electromagnetic field, cause water molecules to strenuous exercise, friction heat, making the wood drying.Microwave on the drying of wood internal direct action, is called a "hot"."Heating" need time and the thickness of the wood, and microwave frequency and intensity of electric field, and the dielectric properties of the wood.Effect of microwave timber, when the internal temperature higher than 100 °C, excessive water vapor pressure in the wood, accelerate the mobile water molecules.So the speed of microwave drying of wood is greatly higher than that of convection drying (natural drying, steam drying, infrared drying, etc.).With microwave drying is generally selected wood microwave frequency is 915 MHZ, 80mm penetration depth of microwave, the microwave frequency is 2450 MHZ, 50 mm penetration depth, therefore can meet the general processed to complete the finished product.For the requirement of the drying and the size of the output of different, can choose different forLD of microwave drying equipment;For various properties of wood to select suitable microwave heating speed, the LD process conditions, can get the LD benefit.
the characteristics of
1, quick drying speed, high efficiency.According to the data show that 25 ~ 50mm pine wood drying speed is faster than common convection drying speed 20-30 times.Lumber moisture content from 30% to 12%, need to 15 to 25 minutes.
2, uniform drying wood, not deformation, not cracking.Wood by microwave and internal and external parts, even heating, so the wood treated by microwave, uniform drying thoroughly, improve product quality, the surface will not harden, improve the toughness, not cracking, deformation, discoloration, adjustable bending, etc.
3, moth-proofing, mouldproof, prolong shelf life.Microwave drying wood, can penetrate inside the wood, the use of timber in the parasitic eggs soon kill, moth-proofing, mouldproof, prolong shelf life.
4, high efficiency and enerLD saving.With far infrared ray and steam enerLD in wood drying, its enerLD utilization rate of less than 50%, but with microwave enerLD utilization rate can reach more than 75%, more than 25% lower than the far infrared and the enerLD consumption of steam drying.
5, easy to operate, save manpower.By using the principle of microwave can be instantly switch, easy operation, convenient management, reduce labor intensity, saving manpower.
6, safety and health, environmental protection.Microwave processing of wood no noise, no pollution, more won't produce the problem of "three wastes".
