The purpose is to supply the necessary moisture in the storage compartment so that fresh produce can be stored for a long time.

Generally, when storing agricultural products such as sweet potatoes, potatoes, onions, garlic, etc., it is a cooler driven by a temperature sensor installed in a storage compartment. It was configured to maintain a proper temperature in the storage chamber by circulating in a top down method of repeatedly discharging to the upper chamber.

In the conventional agricultural product storage as described above, agricultural products such as potatoes, potatoes, etc. are cured in a separate facility before storage, or agricultural products such as garlic, etc. are dried for storage, and then stored in the storage. Conventional low-temperature storage room is configured to circulate only the air in the storage room with a cooler top-down method without a humidification device to control the temperature, so that the storage itself cannot be cured or roughly dried. There is a problem in that the freshness of the discharged carbon dioxide is stored in the reservoir as the air is dried and the humidity is insufficient, so that the produce is dried more than necessary and the freshness is decreased. In winter, it uses cooler that consumes a lot of power to control the temperature. There was a non-economic issues.

In the present invention, in order to solve the problems of the conventional cold storage as described above, and to store fresh produce such as sweet potatoes, potatoes, onions, garlic, pepper, etc. for a long time, the outside is opened by a temperature sensor in the storage chamber duct of the cold storage. Heater operated by air inlet and temperature sensor and blower which are sucked and blown are installed to heat storage room air with heater according to the object to be stored so that curing work can be done in storage room or drying work for storage. In case of curing, the storage room air is returned to the blower, and the respiratory heat and carbon dioxide generated from the curing work are discharged to the air discharger to adjust to the first set temperature. Blowing the outside air sucked into the outside air inlet by the blower, After being humidified while passing through the circulation passage at the bottom of the storage compartment, it is discharged into the storage compartment through a vent cover (grouting) covering the circulation passage at the bottom of the storage compartment. It is configured to store agricultural products freshly for a long time by maintaining the set temperature by repeatedly being discharged to the circulation passage by the blower again with the air drawn in from the outside, and the blown air is humidified in the reservoir and discharged to the storage compartment, In winter, the cooler is stopped and the external air sucked into the inlet by the blower is heated and blown with a heater to economically operate the storage.

If described in detail the configuration and operation according to the accompanying drawings as follows.

The cooler 110 operated by the internal temperature sensor 140 in the storage compartment 101 and the duct 120 and the circulation passage 130 are installed on the wall and the bottom for air circulation, respectively. In the (100), the outside air inlet 10 is installed outside the duct 120 and the outside air flows; A heater 20 installed inside the duct 120 to heat internal and external air sucked into the duct; A blower (30) installed below the heater (20) for sucking and blowing air in the duct (120); A water storage chamber 40 installed at the circulation passage 130 to humidify the heated air passing through the circulation passage 130; An external temperature sensor 50 installed outside the storage compartment 101 to sense a temperature difference from the inside to operate the heater 20 and the cooler 110; Installed in the roof of the storage compartment 101 is operated by the internal temperature sensor 140 is composed of an air discharger 60 for discharging the indoor air.

In the embodiment of the present invention, the air inlet 10 is opened by the detection signal when the internal temperature sensor 140 detects an increase of 0,5 ℃ to 2.0 ℃ than the set temperature of the storage compartment 101, the outside The temperature sensor 50 detects a difference between the set temperature of the storage compartment 101 and an external temperature of 5 ° C. to 10 ° C. and operates the heater 20 by the detection signal to prevent the storage room temperature from suddenly falling when inflow of external air. And, the air discharger 60 is activated when the internal temperature sensor 140 of the storage compartment 101 detects the set temperature or more to discharge the heat so that the set temperature does not rise to adjust the temperature, the reservoir ( 40 may be performed only on a part of the circulation passage 130, and the bubble generator 70 is installed in the reservoir 40 to facilitate evaporative humidification.

In the drawing, reference numeral 111 denotes a freezer for a cooler, and 112 denotes a control box in which operating circuits such as a blower, a heater, an air discharger, and an air inlet, which are operated by a sensor.
