Hereinafter, with reference to the accompanying drawings will be described a cooling system of a grain storage device according to a preferred embodiment of the present invention and a method for natural cooling, preventing condensation and low temperature storage management of grain using the same.

First, the cooling system 100 according to the present invention covers an upper portion of the grain storage chamber 12 and the grain storage chamber 12 in which the top is open and the blower 11 is mounted on one side of the bottom, and an exhaust fan (not shown). And an exhaust chute 14 having a conical roof structure 16 mounted thereon. The cooling system 100 has a cooler 110 disposed at an upper position adjacent to the top of the roof structure 16 while the air supply fan 112 is built therein, and one end of the cooling system 110 is connected to the air supply fan 112, and the other end of the roof structure 16 is provided. End of the second guide pipe 116 and the second guide pipe 116 connecting the first guide pipe 114, one side of the cooler 110 and the upper end of the roof structure 16 connected to the radially lower side of the first guide pipe 114, The first damper 118 disposed on the roof structure 16 and intermittently connected to the second guide pipe 116 and the roof structure 16 and the air supply fan 112 are disposed adjacent to the first guide pipe 114 and the air supply fan. The second damper 120 to control the 112 and the third damper 122 mounted on the upper end of the roof structure 16 to communicate with the interior of the roof structure 16 is provided. In addition, the cooling system 100 is disposed between the upper portion of the grain storage chamber 12 and the lower portion of the roof structure 16, the first sensor 130 for detecting the upper temperature, the agent for detecting the outside air temperature of the grain storage device 11 A second sensor 132 and a third sensor 134 for detecting the outside humidity of the grain drying apparatus 10 is further provided.

Hereinafter, a method of cooling the grain in the grain storage device 10 by using the cooling system 100 formed as described above will be described.

First, after the cooling system 100 is mounted on the grain storage device 10 (step S1), the interior of the grain storage room 12 and the roof structure 16 in which the grains harvested using the urethane are stored are thermally insulated ( Step S2). As such, when the outside air temperature of the grain storage device 10 is lowered to -5 ° C or lower in the state where the cooling system 100 is installed and insulated, the blower 11 is operated until the grain temperature of the grain reaches -3.5 ° C. Natural cooling by blowing air for a total of 100 hours for at least 60 minutes up to 10 hours at a time (step S3). At this time, the cooler 110 and the air supply fan 112 of the cooling system 100 operates in a stopped state, and the first damper 118, the second damper 120, and the third damper 122 are blocked. do.

First, after the cooling system 100 is mounted on the grain storage device 10 (step P1), the interior of the grain storage room 10 and the roof structure 16 in which the grains harvested using the urethane are stored are thermally insulated ( Step P2). As such, when the outside air temperature of the grain storage device 10 is lowered to -5 ° C or lower in the state where the cooling system 100 is installed and insulated, the blower 11 is operated until the grain temperature of the grain reaches -3.5 ° C. Natural cooling by blowing air for a total of 100 hours for at least 60 minutes up to 10 hours at a time (step P3). As the naturally cooled grains, on average, as the outside air increases from March of the following year, the upper grain temperature of the grain layer rises higher than the outside temperature, so that condensation occurs inside the grain storage chamber 12 and the roof structure 16. In order to prevent such condensation, when the outside air temperature is different from the temperature of the upper grain temperature of the grain storage chamber 12 by 4 ° C. or more at a temperature of 15 ° C. or less, the difference between the temperature of the upper grain temperature of the grain storage chamber 12 and the outside temperature is 2.5.

And the third damper 122 is opened so that outside air flows into the grain storage chamber 12 after passing through the first guide pipe 114, the air supply fan 112, and the second guide pipe 116. Maintain the difference between upper and outside air temperature below 2.5 ℃.

Hereinafter, a method of low temperature storage management of the grains in the grain storage device 10 at 15 ° C. or lower by using the cooling system 100 formed as described above will be described.

Similarly, after the cooling system 100 is mounted on the grain storage device 10 (step L1), the interior of the grain storage room 12 and the roof structure 16 in which the grains harvested using the urethane are stored are thermally insulated (step L1). L2). As such, when the outside air temperature of the grain storage device 10 is lowered to -5 ° C or lower in the state where the cooling system 100 is installed and insulated, the blower 11 is operated until the grain temperature of the grain reaches -3.5 ° C. Natural cooling by blowing air for a total of 100 hours for at least 60 minutes up to 10 hours at a time (step L3). In order to store the naturally cooled grains until the harvest of the following year, when the upper temperature of the grain storage chamber 12 rises by 15 ° C. or more, the cooler 110 is operated to warm the air until the internal temperature of the grain storage chamber 12 reaches 15 ° C. or less. Circulating to prevent the rise of the upper grain temperature (step L4). In this case, the blower 110, the air supply fan 112, and the exhaust fan (not shown) are stopped and the cooler 110 operates, and the third damper 122 blocks the first damper 118. And the second damper 120 is opened to circulate until the upper air of the grain storage chamber 12 is 15 ° C. or less.

As described above, according to the present invention, by mounting the cooling system 100 in the grain storage device 10, it is possible to maintain the same level as when harvesting the grains by allowing natural cooling, condensation prevention and low temperature storage. In other words, the low-drying reduces the share rate and maintains good quality throughout the year, which can increase the income of farmers.
