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 unit 20 and the heater unit 30 until necessary temperature information reaches the predetermined temperature information from the temperature information detected by the sensor unit 60.

6 and 7, the agricultural product storage system according to another embodiment of the present invention is different from the embodiment of the present invention in that the agricultural product storage system is provided inside the storage means 10 having the tuyeres 13 formed therein, The heating unit 100 is additionally provided, and the remaining constitution is the same as that of the embodiment of the present invention, so a detailed description thereof will be omitted.

The warming unit 100 reduces the flow rate of the external air introduced from the blowing unit 20 so that the injection duct 40 made of a thin vinyl material is broken due to the flow velocity of the external air rapidly flowing by the blowing unit 20 And also diffuses the flow of the external air introduced from the blowing means 20 in a radial manner to delay the residence time and reheat the external air flowing into the injection duct 40 to a higher temperature And includes a flow rate reduction plate 101 and a reheating plate 102.

The flow rate reduction plate 101 has a hollow circular plate shape and is fixed to the inside of the blowing means 20 of the one side of the storage tank 10 in which the blowing port 13 is formed, A plurality of bending pieces 101a are formed so as to be spaced at regular intervals along the circumferential direction and a cutout portion 101b is formed at a predetermined interval between the bending pieces 101a.

The flow rate reduction plate 101 is configured such that the external air rapidly flowing from the blowing means 20 to the cutout 101b hits the bent end of the bent piece 101b to form a vortex in a certain direction Thereby reducing the flow rate of the outside air passing through the flow rate reduction plate 101. [

Accordingly, it is possible to prevent the injection duct 40, which is made of a thin vinyl material, from being damaged due to the flow velocity of the outside air rapidly flowing through the blowing means 20. [

The reheating plate 102 is fixed to the inside of the flow rate reducing plate 101 of the one side of the storage tank 10 where the tuyeres 13 are formed and is formed into a conical shape whose center is protruded outwardly of the reservoir 10, An inclined surface 102a inclined inwardly of the reservoir 10 is formed along the circumferential direction and a plurality of holes 102b are formed in the inclined surface 102a.

Although the reheating plate 102 is shown as a conical shape in the present embodiment, the present invention is not limited thereto, and the reheating plate 102 may be formed in a hemispherical shape with its center protruding outward in the reservoir.

The reheating plate 102 is heated by receiving power from the outside, and is heated rapidly as a plurality of holes 102b are formed on the surface thereof. Due to the above structure, the reheating plate 102 passes through the flow rate reducing plate 101, The external air flows radially through the inclined surface 102a to increase the residence time and reheat the external air to the interior of the storage tank 10 to a higher temperature.

The reheating plate 102 disperses the flow of the incoming external air radially through the inclined surface 102a to increase the residence time and reheat the outside air using the same electric power as the heater 30 described above, The heating efficiency is further improved.

As described above, in the agricultural product storage system according to another embodiment of the present invention, since the warming unit 100 for warming the external air introduced into the storage 10 to a higher temperature is further provided, It is possible to appropriately supply the outside air introduced into the storage tank 10 to a predetermined desired temperature even in the winter season.

FIG. 8 illustrates a flow of air flowing into a heating section according to another embodiment of the present invention.

8, when external air flows into the warming unit 100 at a high flow rate through the blowing means 13, the air flows into the cutout 101b of the flow rate reducing plate 101, As a result, the vortex is formed in a certain direction as in A, and the flow velocity in the traveling direction of the external air flowing through the hollow is decreased due to the influence of the vortex formed.

As the flow of the external air having flow rate reduced through the flow rate reduction plate 101 flows into the reheating plate 102 and the flow is radially dispersed along the inclined surface 102a of the reheating plate 102 to increase the residence time Is heated sufficiently by the reheating plate 102, and then flows into the reservoir 10.

As described above, according to the agricultural product storage system according to another embodiment of the present invention, since the warming part 100 is further provided, the flow of the external air rapidly introduced by the blowing means 20 causes the injection duct 40, And the temperature of the outside air flowing into the storage tank 10 is increased to a higher temperature, so that the outside air flowing into the storage tank 10 can be discharged into the storage room 10 even in the extreme winter, It is possible to appropriately supply a predetermined desired temperature.

Although the present invention has been described in connection with the preferred embodiments, it is possible to make various modifications and variations without departing from the spirit and scope of the invention. It is, therefore, to be understood that the appended claims will include all such modifications and changes as fall within the true spirit of the invention.
