Description

  The present invention relates to a low temperature drying chamber for drying far infrared rays of vegetables, fruits and wood at a low temperature of 30 to 50 ° C.

In general, when drying wood, etc., the wood loaded on the carriage is carried into a drying chamber, the temperature of the drying chamber is raised to 35-60 ° C. by a heater, an air flow is introduced into the drying chamber by a blower, and a dehumidifier With this, the moisture in the drying chamber is discharged, and the wood and the like are gradually dried.
However, since such a low-temperature drying apparatus takes time to dry, it has been required to shorten the drying time. Moreover, since it was necessary to provide the dehumidifier etc. which discharge | emit water | moisture content, there existed a problem that a running cost and installation cost started.

Therefore, a low-temperature drying apparatus, a panel body, and a panel body assembly method that reduce the drying time and cost are known (see Patent Document 1).
In this known technique, a dry object (3) such as wood loaded on a carriage (2) is carried into a drying chamber (5), outside air is taken into a duct part (11) by a blowing means (13), and heating means ( 12) is heated to be hot air and contains far-infrared rays by the ceramic body (14) and discharged into the adjustment duct (8), and the hot air is discharged from the adjustment duct (8) into the partitioning side surface (16) and the wire mesh. (18) A low-temperature drying device that distributes the air to the drying chamber (5), circulates hot air in the drying chamber (5), and discharges wet heavy air to the outside of the drying chamber 5 from the discharge port (31). (1).

In addition, in order to remove the growth stress before drying the wood, as much as possible far infrared rays with high thermal efficiency are used as the heat source at a relatively low temperature (60 ° C to 80 ° C) heating room temperature that does not impair the material color. A wood heat treatment furnace by far-infrared breeding that attempts to remove the growth stress in 2 to 3 days and greatly reduce the cost by generating it is known (see Patent Document 2).
This known technique is often achieved by burning a woody fuel (2), placing a rooster (4) on the top of the flame, and placing a porous ceramic or a nearby volcanic lava (5) on it to make it red hot. Far-infrared rays are generated, and the hot air passes through the air passage (6) into the far-infrared breeding chamber (22) adjacent to the far-infrared breeding ceramic or high-density lava (23) with an appropriate gap. Passing through the inside of the deposit while making the heat, and passing through the platinum mesh or stainless steel mesh (21) in the air hole (20) provided in the wall surface (28) of the heating chamber (27) while accumulating heat and further far infrared rays. This is a wood heat treatment furnace by far-infrared breeding configured to fill the heating chamber (27).

  Any of these known techniques are consistent in that the far-infrared light source that uses far-infrared rays in the drying of wood is ceramic, but because it is a single location, unevenness occurs in the overall drying, and uniform drying is not possible. It was difficult.
