Description
BACKGROUND OF THE
Generally, the agricultural product store is a warehouse used for storing agricultural products such as sweet potatoes, potatoes, onions, garlic, and the like.
The agricultural products stored in the agricultural product storage are susceptible to temperature or humidity depending on the kind thereof, so if the temperature or humidity inside the storage warehouse is inadequate, the stored agricultural products may be deteriorated or corrupted.
Especially, sweet potatoes among agricultural products are sensitive to temperature. If they are kept at a low temperature of 9 ℃ or lower, they will lose their flavor and sprout. Also, resistance to germs will be weakened, The action becomes vigorous and not only the consumption of nutrients increases, but also the problem that the value as a commodity drops greatly due to shoots.
In addition, sweet potatoes have a moisture content of about 60 to 70%. If the storage humidity is lower than the above range, the shell hardens and shoots and roots are not generated. If the storage humidity is high, moisture is formed on the surface, A problem arises.
In addition, in the case of sweet potato, moisture and carbon dioxide are generated by self-respiration. If fresh air is not supplied periodically from outside, there is a problem of suffocation due to increase of carbon dioxide.
Korean Unexamined Utility Model Application Laid-Open No. 1999-0038064 discloses an agricultural product low-temperature storage structure having a cool air discharge opening for discharging cool air to both sides and a cooler having a suction fan installed at the bottom thereof on one side of the ceiling.
The cold storage tank of the agricultural product is a structure that keeps the temperature inside the low temperature storage tank constant by cooling the air inside the sealed low temperature storage tank and circulating it through the cooler.
However, although the internal temperature of the low-temperature storage reservoir can be maintained constantly by circulating the air inside the sealed low-temperature storage reservoir repeatedly through the cooler, air is introduced from the outside into the low-temperature storage reservoir When storing agricultural products that emit carbon dioxide through self-respiration, such as sweet potatoes, there is a problem that the stored agricultural products are suffocated due to the increase of carbon dioxide in the low-temperature reservoir.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide an apparatus and a method for supplying fresh outside air to a storage room storing agricultural products, while maintaining the temperature and humidity inside the storage room at a preset temperature and humidity And an agricultural product storage system.
Another object of the present invention is to provide a heating unit for reheating external air introduced into a storage space by decreasing a flow rate of external air supplied from a blowing unit and radially dispersing a flow of external air to increase a residence time, And to provide a further agricultural product storage system.
According to an aspect of the present invention, there is provided an air conditioner comprising: a closed storage space in which agricultural produce is stored; a reservoir formed at a lower side thereof with a tuyer for inflow of outside air; A blower means for forcibly supplying outside air to the inside of the storage space and a heater portion provided on the outside of the blower means on one side of the storage space on which the blower port is formed and for heating external air flowing into the blower means, And a plurality of spray holes formed in the outer circumferential surface of the spray duct for spraying outside air heated in the storage space, and a plurality of spray ducts installed at one side of the inside of the pool, And a sensor unit for detecting humidity information and a sensor unit for detecting the temperature information and humidity information in advance And a control unit for controlling the operation of the air flow-in unit and the heater unit by comparing the set temperature information and the humidity information. The heater unit includes a plurality of heater rods formed in a bar shape and spaced apart from each other by a predetermined distance in the vertical direction, And a plurality of contact pins spaced apart from the outer circumferential surface of the heater rod by a predetermined distance.
The controller may further include a humidifier configured to spray water mixed with sterilizing material into the storage space, wherein the controller compares the humidity information detected by the sensor with preset humidity information, It is preferable to control the driving of the humidifying unit.
It is preferable that the controller compares the temperature information and the humidity information detected by the sensor unit with preset temperature information and humidity information to control the driving time of the heater unit and the humidifier unit.
In addition, since the one side of the storage room on which the tuyeres are formed is provided inside the blowing means, the flow rate of the outside air supplied from the blowing means is reduced, and the flow of outside air is radially dispersed to increase the residence time And a warming unit for reheating the outside air flowing into the storage room.
Here, the warming portion is formed in a hollow circular plate shape and is installed on the inside of the blowing means of the one side of the storage room where the blowing port is formed, and the bent piece of the 'A' A flow rate reduction plate having a plurality of cut-away portions spaced apart from each other by a predetermined distance between the bending pieces and a conical or hemispherical shape having a center protruding outward from the reservoir, And a reheating plate having an inclined surface inclined in an inner direction of the reservoir along a circumferential direction and having a plurality of holes formed in the inclined surface.
The air conditioner according to
It is further preferable that the injection duct is formed of a material which can be stretched and expanded so as to be folded and stored at one side of the storage case when the outside air heated to the inside of the storage is not supplied.
According to the present invention, fresh external air is periodically supplied to the inside of a storage room storing agricultural products, and temperature and humidity inside the storage room are kept at a preset temperature and humidity, This method can prevent the sweet potato from suffocating due to the increase of carbon dioxide generated by self-breathing of sweet potatoes.
As a result, sweet potatoes can be preserved for a long period of time in a state in which fresh sugar and high sugar content are maintained, so that they can be continuously supplied even during the non-harvesting period of sweet potatoes.
In addition, since the heating unit for warming the outside air to a higher temperature is further provided, the outside air flowing into the inside of the storage can be appropriately supplied to a predetermined temperature even in the season of the extreme winter when the temperature of the outside air greatly decreases.

Here, the preset temperature information can be set to various temperatures at which the optimum storage condition of sweet potatoes can be maintained. However, in the present invention, preset temperature information is set in the range of 12 ° C to 15 ° C in consideration of the characteristics of sweet potatoes, Lt; 0 > C.
In case of sweet potatoes, it is weak at low temperature (less than 12 ℃). If it is kept at low temperature for a long time, it will become cold, it will change in flesh and taste and will not sprout. It will be less resistant to germs and rot. On the other hand, at high temperature (above 15 ℃), the consumption of sweet potatoes increases and the value of the product drops significantly because of the sprouts.
The preset humidity information can be set to various humidity levels in which the optimum storage condition of the sweet potato can be maintained. However, in the present invention, the preset humidity information is set in the range of 85% to 95% desirable.
In the case of sweet potatoes, moisture content is 60% ~ 70%. Therefore, in case of low humidity (below 85%), sweet potatoes lose their moisture and their roots become hard as they harden. When the temperature is lowered, moisture forms on the surface of the sweet potato, so the heat conduction is deteriorated and the sweet potato is liable to decay.
The control unit 70 may include a timer and may control the driving time of the blowing
