アップになり易いものであった。Problems that the invention aims to solve However, the raw wood must be left to dry naturally for several years, and it takes a lot of effort to periodically change the orientation and top and bottom of the wood, resulting in a large number of expensive pieces of wood being left to dry. If left unattended for many years, you will waste money, and it will also easily become distorted when it absorbs moisture again.
In addition, in forced drying using a drying room, the
While blowing hot air, the evaporated moisture is exhausted to the outside along with the hot air, so the energy retained in the hot air is likely to be wasted, and like natural drying, force-dried wood may absorb moisture again after treatment and become distorted. However, it is easy to twist, and since drying treatment and chemical treatment for killing insects are used in combination, pretreatment of the wood requires too much expense, which tends to increase costs.

へ搬出するものである。Effects In the wood drying apparatus according to the present invention, the front door 17 of the sealed chamber 2 is opened, and the board material 24 obtained by sawing and splitting raw wood is transferred to the trolley 16.
The first wood drying device 18a is placed at an appropriate height via a crosspiece, then carried into the drying room 10, and the door 17 is closed.
In this case, the combustor 8 like a burner is ignited and the '14 tube 6 is ignited.
is heated and a fan 12 provided on the side of the hot air generation chamber 9 is rotated to send the radiant heat from the 16 tubes 6 into the drying chamber 10 through the gap between the air direction adjustment plate 4 and the inner surface, and into hot air.
While circulating the hot air that has passed through the gaps between the plates 24 of the truck 16 into the hot air generation chamber 9 again, the temperature inside the drying chamber 10 is lowered to 1.
The temperature is raised to 50 to 200C, and at the same time, cold water is continuously passed from the outside into the dew condensation water pipe 13 provided on the inner wall surface of the drying chamber 10. When the temperature inside the drying chamber 10 rises and the temperature of the plate material 24 placed on the trolley 16 rises, the moisture within the plate material gradually evaporates, and the hot air circulating from the hot air generation chamber 9 into the drying chamber 10 is piled up. Each time it passes through the gap between the plate materials 240, it becomes moist hot air, and the moist hot air hits the condensing water pipes 13 and condenses moisture. It collects in the tray 14 and is discharged to the outside of the drying chamber 10. In order to reduce the occurrence of uneven drying of the plate material 24, the 7-ring 12 controls the flow direction of the hot air while rotating forward and reverse at intervals. After the condensed water has been discharged by hot air drying for about 20 hours, the combustor 8 is stopped, and the hot air generation chamber 9 and drying chamber 10 are heated while the fan 12 is continuously rotated.
The plate material 24 is cured and dried at a high temperature for about 20 hours using the residual heat inside the wood, and a part of the structure of the material is chemically rendered unrecoverable.
Thereafter, the door 17 is opened and the plate material 24 is carried out together with the cart 16.

のである。In the second wood drying device 18b, a hot air generation chamber 9 is provided on the side of the drying chamber 10, and firewood and scraps are put into the combustion furnace 21 and burned while heating the furnace tube 6. The radiant heat from the fuze 6 is sucked by the upper fan 12 and blown as hot air above the wind direction adjustment plate 4, and the high temperature hot air is passed through the gap between the air direction adjustment plate 4 and the inner surface into the drying chamber 10. Moisture is passed through the gap between the plates 24 mounted on the partition wall 20 to evaporate the moisture, and the moist hot air is brought into contact with each condensation water pipe 13 of the partition wall 20 to condense the moisture while passing through the ventilation hole 23 to the hot air generation chamber 9. The lumber carried into the drying chamber 10 is dried at a high temperature in the same process as the first lumber dryer 18a.

するものである。As mentioned above, in the wood drying device according to the present invention,
High-temperature hot air is circulated into the drying chamber from a sealed hot air generation chamber, and the moist hot air that evaporates the moisture contained in the material is brought into contact with the condensation water pipe to cause dew, and the condensed water is discharged outside the room to complete the drying process. The wood structure is made into an asphyxia-strengthened structure and adhered to each other in the steps, and as hot air is not discharged outside, there is little loss of combustion energy. It is possible to have an anti-mold effect, the structure of the wood becomes an asphyxia-strengthened structure, which reduces the deformation of the wood and improves its resistance to outside air, and the equipment is simple and the drying cost is low. It is effective.
