Description

DETAILED DESCRIPTION OF THE INVENTION [Prior Art] Conventionally, many drying apparatuses for producing dried fish and shellfish products use dehumidified cooled air.

However, in conventional drying apparatuses, the water content of the material to be dried is removed only by drying air, which has the disadvantage that it takes time to dry, and the sterilization effect cannot be expected, leading to a decrease in quality.

[Object of the present invention]

The present invention provides infrared and ultraviolet lamps in the drying chamber that stores the items to be dried.The infrared rays can increase the surface temperature of the items to be dried and shorten the drying time, and the ultraviolet rays can sterilize the items and dry air. By doing so, we were able to obtain products of good quality.

[Example of the present invention]

FIG. 1 is a diagram showing an embodiment of a cold air drying apparatus according to the present invention. In the same figure, the symbol l indicates a device chamber body, which is divided into a machine room 3 and a drying room 4 by a partition plate 2.
A compressor 5, a condenser 6, and a cooler 7 for a dehumidifier are installed in the machine room 3, and the air from the drying room is passed through the cooler 7.
The dehumidified and cooled air liquefies the refrigerant in the condenser and is sent by a fan 8 through a ceiling duct 9 and from a side duct 10 to the drying room, and is sent to the machine room and the drying room. are dampers 11a that are opened by motors 13a and +3b when the temperature rises, respectively.
, llb, respectively, an outside air intake port 12a and an exhaust port 1
2b is provided.

In addition, an infrared lamp 14a and an ultraviolet lamp 14 are installed in the drying room.
b.

In the figure, reference numeral 15 indicates a shelf on which items to be dried, such as fish and shellfish, are placed, and 16 indicates a damper motor 13a in front.
a thermostat that emits a signal to activate 13b, 17;
is a gear rally that sucks air from the drying room into the cooler.

In the apparatus of the present invention described above, the fish and shellfish placed on the shelf 15 in the drying chamber are dried by removing moisture from them by the dehumidified cooling air flowing approximately horizontally within the drying chamber.

However, in the apparatus of the present invention, since the infrared lamp 14a is disposed in the drying chamber, the surface temperature of the fish and shellfish is increased by the infrared rays, and more water is evaporated than if only dry air were used.

These moistures are removed by dry air, and the moisture-containing air is dehumidified by a cooler (7) and circulated by a fan (8) to dry the material to be dried.

Further, since an ultraviolet lamp 14a is also provided in the drying chamber, the objects to be dried and the circulating air are sterilized by ultraviolet rays.

Furthermore, when the temperature inside the device room increases, the thermostat (+e) installed in the duct (9) detects the temperature rise, and each damper Ila of the outside air intake port 12a and the exhaust port 12b,
11b is opened to exchange air and prevent excessive temperature rise.

[Effects of the present invention]

As described above, according to the present invention, the surface temperature of the object to be dried is raised by infrared rays, moisture is evaporated at a faster rate than conventional methods, and drying can be carried out in a short time. In addition, since the action of ultraviolet rays not only sterilizes the material to be dried but also the circulating air, there is no risk that the quality of fish and shellfish will deteriorate during drying.

Furthermore, when the temperature inside the apparatus chamber rises abnormally, the inside of the apparatus chamber can be maintained at a required temperature by introducing outside air.

Further, ultraviolet rays react with oxygen in the air to generate ozone, and since ozone has antiseptic and sterilizing effects, this also has the effect of preventing the quality of the dried material from deteriorating.
