[0015]

According to the first aspect of the present invention, since the drying chamber is provided, the material to be dried can be accommodated in the drying chamber together with the drying humidity-controlling agent, and the dry humidity can be suitably adjusted. Further, when the dry humidity control agent is dried and regenerated, the dry humidity control agent can be easily regenerated by housing the dry humidity control agent in the drying source chamber and heating it by the microwave generation unit. . The steam and odorous gas generated from the dry humidity control agent during the dry regeneration can be processed by the exhaust processing unit.

A magnetron can be used as the microwave generator, and the drying and conditioning agent can be dried and regenerated by the microwave generated from the magnetron. In the invention of claim 2, as the dry humidity control agent,
For example, silica gel of A type, B type, ID type, RD type, etc. can be adopted. In addition to silica gel, for example, synthetic zeolite can be used.

According to the third aspect of the present invention, the connection between the drying chamber and the drying source chamber can be opened and closed by, for example, a sliding door-shaped mesh door, or the like, or the state in which the drying chamber and the drying source chamber communicate with each other. It is set to the state where communication is cut off. Therefore, for example, when the material to be dried is dried in the drying room, the door can be closed to prevent the dry humidity control agent from falling from the drying room into the drying source room, and the used dry conditioning agent can be used. When the moisturizer is moved to the dry source chamber, the door can be opened and the dry moisturizer can be dropped and moved from the dry chamber to the dry source chamber.

According to the fourth aspect of the present invention, since the catalyst deodorizing section is provided as the exhaust processing section, the odor generated when the dry humidity control agent in the drying source chamber is regenerated is suitable for the honeycomb catalyst, for example. Can be deodorized. In the invention of claim 5,
In the case of performing dry humidity control of the material to be dried, the material to be dried and the dry humidity control agent can be arranged in the drying chamber to perform the dry humidity control under desired dry humidity control conditions. Therefore, rather than the extreme drying like the conventional forced drying, it is possible to preferably perform the dry humidity control at an appropriate drying speed.

According to the sixth aspect of the present invention, when the humidity of the material to be dried is controlled, the material to be dried and the dry humidity control agent are placed in the drying chamber, and the dry humidity control agent is also placed in the drying source chamber. However, since the drying chamber and the drying source chamber are communicated with each other and the air is circulated between the both chambers, the dry humidity control can be performed more quickly than in the case of the fifth aspect.

According to the invention of claim 7, as a method of circulating air between the drying chamber and the drying source chamber, the air is circulated by a fan in a state where the drying chamber and the drying source chamber are in communication with each other. The method of doing can be adopted. In this way, not natural convection,
Since the air is circulated by the fan, it is possible to more quickly perform the dry humidity control.

According to the eighth aspect of the present invention, the dry humidity control agent can be dried and regenerated by heating the microwave generation section with microwaves while the dry humidity control agent is arranged in the drying source chamber. In this case, as the dry humidity control agent to be dried and regenerated,
The thing used for the dry humidity control of the to-be-dried material in the drying room is mentioned. For example, when the drying chamber is provided directly above the drying source chamber, by dropping the drying humidity control agent in the drying chamber as it is into the drying source chamber, the dry regeneration condition of the drying humidity control agent is prepared. .

In the ninth aspect of the present invention, when the dry humidity control agent in the drying source chamber is dried and regenerated, the odor generated from the dry humidity control agent is guided to the catalyst deodorizing section by the fan, so that the odor is transmitted from other locations. There is no risk of leakage, and deodorization can be performed efficiently. According to the tenth aspect of the present invention, when the drying / humidifying agent in the drying source chamber is dried and regenerated by the microwave generator, the drying chamber and the drying source chamber are shut off so that microwaves do not leak, and therefore, for example, drying is performed. Even if another dry humidity control agent is housed in the room, the dry humidity control agent is rarely affected.

In the present invention, the material to be dried is wood,
In addition to rice and rice, general fish and shellfish such as scallops and oysters,
It can be applied to dried fruits such as dried persimmons, dried grapes and dried shiitake mushrooms. Therefore, for example, in drying wood, if hot air drying by forced hot air circulation as in the past is performed, the temperature becomes locally too high,
Since the diffusion gradient such as temperature difference and humidity difference between the dry air and the object to be dried at the time of drying is too large and cracks occur, it is necessary to dry gently, for example by embedding wood in silica gel. It can be gently dehydrated and dried without cracking.

With respect to rice husks, for example, when silica gel is wrapped in a breathable cloth or paper and mixed into the husks, the water is gently dehydrated and dried, so that cracks and crushing do not occur. If rice is also stored in a closed container, larvae will develop,
Although odor and moisture are generated, if silica gel packaging is mixed and used, for example, it can be kept at a certain humidity to prevent insects, moisture, and odors, and the flavor is not lost.
Nutrients are also retained.

Since fish is dehydrated and dried by packaging and embedding it in silica gel,
You can make delicious dried fish. In addition, since the silica gel used in this way contains water and a malodorous substance, for example, it is heated, dehydrated and regenerated by a magnetron, and
It can be deodorized with a catalyst.

If heating with a magnetron is also used, it is possible to increase the efficiency in drying the material to be dried.
