Specifications

Microwave wood drying equipment’s main features:

1. Fast speed: microwave drying due to its unique advantages, the drying speed is fast. Experiment shows that: when microwave power for about 60 kilowatts. Cause no defects in dry conditions, from 8 mm thick thin board to 50 mm thick the material, incoming water from 35 to 40% drying to about 20% and its drying time only 10 minutes to 26 minutes .If increase power of microwave, must adopt corresponding reasonable process. Otherwise, the drying speed is increased, but because although then wood has risen sharply. Internal temperature of the water, air pressure has soared more than vaporization wood fiber allowed degree, cause craze. So microwave drying wood, the output power density of increase is limited.

2.high efficiency: We use "carry water rate" the index will assess the efficiency of dry. The so-called "carry water rate" is defined as 1 kilowatts of power of microwave in 1 hour, make be dry content of water loss, the unit is number kg/kg KWH (kg/KWH). Carry water rate is high, show the efficiency of the equipment is high. We do four kinds of tree species of the timber in the same specification, under the condition of the assessment. The results show that: all kinds of tree species of water pumping rate in wood 1 kg/KWH or so or slightly more than.

3. Good quality: wood in conventional drying of the change of form, craze, is because the wood fiber uneven contraction after losing water produces. In natural drying, on the one hand, because of the wood surface evaporation speed far outweigh the internal water diffusion degrees, formed the surface in the dry wet form.The surface of drying shrinkage, the fiber produced list of stress between. On one hand, wood along the fiber direction at both ends of the fiber wool stoma far outweigh the other place, so much more than the contraction of fiber the rest of the wood, so actually ends in natural drying almost no cracks and deformation, general the length of the crack in 10 to 30 cm differ, serious a piece of board split or a few pieces of broken plate. At the same time in the green coffees which wood push, long time of the wind erosion of weathered metamorphic repeatedly, causing a lot of wood miLDw, this is out of shape, craze, miLDw metamorphic are seriously affected the quality of wood and caused a large number of scrap. Even dry thoroughly, improve product quality, the utilization rate of wood can be increased by 5% or so. Such as surface will not harden, improve toughness, won't craze, deformation, changing color, the calibration curve for, etc

4.When microwave power density is too large, wood internal vaporization potential "pressure" more than wood fiber are allowed to limit, also can appear wood internal cracking phenomenon. This is the microwave drying wood still need a role of time in principle.

Wood board/veneer microwave stoving machinery, often colloquially shortened to microwave, is a kitchen appliance that heats food by bombarding it with electromagnetic radiation in the microwave dryer spectrum causing polarized molecules in the food to rotate and build up thermal energy in a process known as dielectric heating.Wood board/veneer microwave stoving machinery heat foods quickly and efficiently because excitation is fairly uniform in the outer 25–38 mm of a dense (high water content) food item; food is more evenly heated throughout (except in thick, dense objects) than generally occurs in other cooking techniques. Wood board/veneer microwave stoving machinery can Sterilize the food during the drying process by heat and the influence on the protein, RNA, DNA, cell membrane and so on.
