Using the agricultural product storage device according to the present invention described above will be described for the drying, ripening, and storage method of the received agricultural products.

First, a method of using the agricultural product storage device provided with the multifunction in the housing 10 will be described.

First, as reduced pressure cooling of agricultural products, agricultural products harvested at a high temperature state need to be cooled to a suitable temperature as soon as possible immediately after harvesting to suppress changes in respiratory volume, components, or physical properties of the fruit itself, and to maintain the quality afterwards. This treatment is called cooling.

For this decompression cooling, the operator selects the decompression cooling selector 63 of the control unit 60, and the harvested produce is ventilated in the decompression chamber 71 of the decompression unit 70 isolated in the housing 10. After putting it through the box, the temperature control unit 61 adjusts the internal temperature of the housing 10 to 5-10 ° C., for example, through the freezing means 20 to lower the inside of the decompression chamber 71. The stored agricultural products are stored at 5 to 10 ° C., and the internal air of the decompression air discharge unit 72 is operated to discharge into the interior of the housing 10, so that decompression occurs in the decompression chamber 71, so that the respiration volume of the fruit itself, Changes in components and physical properties are automatically suppressed, and the freshness can be maintained by cooling under reduced pressure.

Subsequently, as the agricultural product is dried, the moisture contained in the agricultural product to be stored in the housing 10 is removed to prevent corruption and to increase storage.

That is, when the dry selection unit 64 of the control unit 60 is selected after arranging the agricultural products to be dried in the housing 10 at a predetermined position, the freezing means 20 and the drying heater unit 80 are operated. Dry air (low-temperature wind) is supplied into the housing 10 through the blower fan 40, and drying is performed in a state in which moisture of agricultural products is removed.

Subsequently, as storage of the agricultural product, the dried agricultural product is stored for a long period of time at a constant low temperature (preferably 3 to 5 ° C) in the housing.

That is, if the storage selection unit 65 of the controller 60 is selected after arranging the agricultural products to be dried in the housing 10 at a predetermined position, the temperature is maintained at a temperature of 3 to 5 ° C. through the freezing means 20. Long term storage is achieved.

In addition, as the ripening of the agricultural product, an operation in which an inadequate flavor or texture is left under certain conditions for a while to have properties suitable for the target agricultural product is referred to as ripening.

For example, in the case of dried persimmon, after arranging the persimmon to mature in the housing 10 at a predetermined position, the ripening selector 66 of the controller 60 is selected, and the temperature adjusting unit 61 and the humidity adjusting unit 62 are selected. If set to 23 degrees and humidity 15 to 30%, respectively, the drying heater 80 and the humidity generating means 30 is operated to 23 degrees by the air supplied into the housing 10 through the blowing fan 40 Humidity is maintained at 15 ~ 30% to complete the ripened persimmon.

In addition, in the case of a banana, the ripening selector 66 of the control unit 60 is selected after arranging the banana to be ripened in the housing 10 at a predetermined position, and the temperature adjusting unit 61 and the humidity adjusting unit 62 are selected. For example, through maintaining the temperature at 15 ℃ first, while increasing the temperature to 19 ℃ by 1 ℃ in about 1 hour, and also to adjust the humidity to be maintained to 90% ~ 95% dry heater unit (80) ) And the humidity generating means 30 is operated so that the banana is ripened at a desired temperature by the air supplied into the housing 10 through the blowing fan 40.
