As the industry develops and human civilization develops, many people live together and live together. As the food culture that follows them develops into a culinary life, the technology that makes the culinary tools more hygienic is managed continuously. Development and improvement.

Accordingly, it has become common for schools, military units, companies, hospitals, and the like to generally use a collective cooking system to collectively use dishwashers formed in uniform shapes and to clean them so as not to store bacteria. Managing hygienic co-catering has become a challenge.

It is important to manage all the tools hygienically in this situation. However, it is one of the most important issues to be more hygienically managed, especially those that contain individual foods.

A plate disinfection apparatus for continuously storing the plates in the disinfection chamber and continuously supplying the heat to the disinfection chamber to continuously maintain the environment in which the bacteria can not be inhabited has been developed and popularized so that a large amount of plates stored in the disinfection chamber are heated through the hot air Disinfection is kept at high temperature.

Conventionally, in the conventional plate disinfecting apparatus, since the air remaining in the disinfection chamber is simply heated by the electric heat supplied from the electric heat supply unit to a temperature higher than the set temperature, the food plate housed in the disinfecting chamber is sterilized at high temperature, It has a limitation that it can not be removed.

That is, since the conventional plate disinfecting hood is not provided with a dehumidifying structure for removing a large amount of water remaining in the disinfection chamber, a large amount of water evaporated from the hot plate heated in the disinfection chamber remains, As a result, the conventional plate disinfecting apparatus has a limitation to continuously supply high-temperature heat in the disinfection chamber in order to prevent the propagation of bacteria in the plate.

An opening and closing port 12 is formed in the front of the main body 10 to open and close the door 100. The opening and closing door 12 is provided with an opening and closing door 13 to close the disinfection and drying chamber 11 .

The shelves 15 are vertically spaced from each other in the disinfection / drying chamber 11 so that the plates 100 are housed in the disinfection / drying chamber 11 in a multi-layered state with the shelves 15 standing upright.

In this embodiment, the disinfecting drying chamber 11 is provided with a plate disposition structure for disposing the disinfecting plates 100 so as to be spaced apart from each other in an upright position, and the disinfecting drying units 11 are disinfected So as to stand in the drying chamber (11).

When the food plates 100 are arranged in the disinfection / drying chamber 11 in a standing state, the water drained on the surface of the plate is stably discharged, and the warm air circulated through the food circulation unit 30 flows into the food plate 100, the moisture on the surface of the plate 100 is rapidly evaporated.

3 and 4, the plate array structure is formed on each shelf 15 of the disinfection and drying chamber 11 and is provided with an alignment frame bar (see FIG. 4) in which gap protrusions 14a and gap grooves 14b are alternately formed 14).

Therefore, the plate 100 standing up in the disinfection / drying chamber 11 by the alignment frame bar 14 has the lower side 101 to be held by the gap groove 14b formed between the gap projections 14a, The disposable diapers 100 are supported on the inner wall of the disinfection drying chamber 11 so that the diaphragms 100 are not in close contact with each other while forming an inclined standing state in the disinfection drying chamber 11, Thereby maintaining the spaced apart state.

The circulation unit 30 for continuously circulating the residual hot air in the disinfection and drying chamber 11 includes a recovery pipe 31 for providing an intake path of the heated air remaining in the disinfection and drying chamber 11, and; A suction fan unit (32) for forcedly sucking the hot air remaining in the disinfection / drying chamber (11) through the return pipe (31); And a re-supply pipe 33 for re-supplying the hot air sucked through the return pipe 31 into the disinfection / drying chamber 11, thereby forcibly circulating the hot air inside the disinfection / drying chamber 11.

Therefore, the hot air heated to a high temperature by the electric heat supplied from the electric heat supply unit 20 is circulated in the disinfection / drying chamber 11, passes through the foodstuffs 100, and evaporates moisture on the surface of the foodstuff 100 The hot air having a large amount of the evaporated moisture is drawn into the circulation unit 30 along the recovery pipe 31 by the suction fan unit 32 and then introduced into the sterilization drying chamber 10 through the re- The internal circulation is performed.

At this time, the hot air circulating in the disinfection and drying chamber 11 is passed through the partition plates 100 separated by the alignment frame bar 14 to stably evaporate the moisture on the surface of each plate 100, The hot air containing the moisture is forcibly drawn into the circulation loop 30. [

Since the circulation of the circulating hot air in the disinfection / drying chamber 11 through the circulation circulation unit 30 is prevented from being discharged to the outside and circulated internally, the heat loss due to the discharge of the hot air is prevented, It is possible to minimize the loss of electric power due to the generation of the sterilization drying chamber 11 and to sterilize the plate at a high temperature as the hot air of the set temperature is continuously supplied into the disinfection drying chamber 11.

However, since a large amount of water evaporated from the food plate 100 is mixed into the warm air circulated through the inner circulation unit 30, even if the internal circulation of the warm air is continuously performed, The internal humidity of the drying chamber 11 is increased, and the drying of the plate 100 is practically impossible.

In order to solve this problem, in this embodiment, a dehumidifying module 40 having a unique dehumidifying structure for dehumidifying the moisture remaining in the hot air recovered in the inside circulation unit 30 is disposed, The moisture remaining in the hot air recovered in the drying chamber 11 is removed and the hot air removed from the disinfection and drying chamber 11 is continuously supplied and circulated.
