Description

The present invention relates to a wood drying apparatus using underground heat and solar heat.

Various configurations are considered for wood drying equipment.For example, wood drying equipment that lowers the moisture content of wood by heating and cooling the wood with steam and further drying repeatedly destroys the cells of the wood. There is also deformation, lusterless wood can be produced, electricity and heavy oil boilers and pressure drying kettles are required as fuel, and the amount of drying is small, so the work process is greatly increased, equipment costs and fuel costs are reduced It is a burden.

Further, Patent Document 1 discloses a wood dryer that applies a water transfer function of a cell membrane. This wood dryer is provided with dry wood in a dryer case, and the dryer case is heated to 30 to 50 ° C. The humidity of the dryer housing is adjusted with a plurality of small windows while the temperature of the dryer is adjusted by moving the moisture of the green material (wood to be dried) to the dry wood of the dryer housing.
However, since this wood dryer adjusts the temperature with a small heater, electricity and the like are necessary, and it is difficult to secure the temperature and adjust the humidity in the dryer housing.

Patent document 2 discloses a wood drying device using solar heat. This wood drying device is composed of a wood drying chamber and a dehumidifying chamber, and the wood drying chamber is side lighting for collecting sunlight. Side walls are provided, gratings on the floor, reflectors on the walls, and wood carry-in / out facilities on the walls and ceiling, warming the wood by collecting plenty of sunlight, promoting evaporation of moisture, In addition, the dehumidification chamber is partitioned by a heat insulating material, and vents for circulating air are provided in the upper and lower parts, and the surrounding wall surface is surrounded by heat insulating material. Metal dew condensation promotion plate, fan, exhaust fan, drainage hole Is provided for dehumidification by condensation of saturated water vapor. However, in this wood drying device, sunlight is incident from the side lighting side wall for collecting sunlight, heat is generated by the grating of the floor, is heated by the reflector on the wall, and is kept at a medium temperature with sunlight. Heating the wood as a drying sunroom evaporates the moisture in the wood, blows it through a fan, condenses saturated water vapor on the metal dew condensation promotion plate in the dehumidification chamber, and drains it. However, there is a temperature difference between the surface irradiated from the side lighting side wall and the surface of the wood wrapped from the reflector and the surface not irradiated, and the wood is distorted. In addition, saturated water vapor whose wood drying chamber has been heated by solar heat is blown to the dehumidification chamber to cause condensation on the metal condensation promotion plate, but the temperature difference is not sufficient and the promotion of condensation is small.
