In addition, in the agricultural and marine products drying apparatus according to an embodiment of the present invention, the degree of drying of the agricultural and marine products is different depending on the volume of the drying chamber and the heating amount of the heating unit, the results of the experiment according to the conditions such as the time is as follows.

Drying chamber volume (㎡) Heating capacity Moisture content after drying (%) One 0.7 4.5 11 2 0.75 4.5 11 3 0.8 4.5 12 4 0.85 4.5 12 5 0.9 4.5 13 6 0.95 4.5 13 7 One 4.5 16 8 1.05 4.5 17 9 1.1 4.5 19 10 1.15 4.5 20

Drying chamber volume (㎡) Heating capacity Moisture content after drying (%) One 0.95 4 19 2 0.95 4.2 18 3 0.95 4.4 17 4 0.95 4.6 14 5 0.95 4.8 13 6 0.95 5 13 7 0.95 5.2 12 8 0.95 5.4 11 9 0.95 5.6 10 10 0.95 5.8 10

In Table 1 and Table 2, the moisture content before drying of the agricultural and aquatic products was 84%, and referring to Table 1, the moisture content after drying was excellent when the drying chamber volume fell below 1 m 2. However, below 0.9 m 2, the water content after drying did not significantly decrease.

Referring to Table 2, the moisture content was excellent after drying at a heating capacity of 4.6 kPa or more. However, at 5 kPa or more, the water content after drying did not significantly decrease.

That is, in the agricultural and marine products drying apparatus according to an embodiment of the present invention, excellent drying of the agricultural and aquatic products is possible at a drying chamber volume of 0.9 m 2 to 1 m 2 and a heating capacity of 4.6 kV to 5 kPa. However, the water content of the agricultural and marine products is lower after drying in the drying chamber volume of less than 0.9 m 2 and the heating capacity of more than 5 kPa, but the drying efficiency is worse than that of the supplied energy, and the agricultural and marine products located at a distance from the heat exhaust port and the agricultural and marine products located at a distance from the exhaust outlet. Color difference occurs. Therefore, it is preferable that it is a dry chamber volume of 0.9 m <2> -1m <2>, and a heating capacity of 4.6 kPa-5 kPa.

Agricultural and marine products drying apparatus according to the prior art has a problem that efficient drying is difficult, such as the difference in color according to the drying position of the agricultural and marine products because the drying air is directly supplied to the agricultural and marine products. Furthermore, the tray 500 on which agricultural and marine products are loaded is arranged in multiple stages, and the temperature and flow pressure of the air decreases toward the tray 500 that flows from the tray 500 that is disposed on the side where the heated air is introduced. Has the disadvantage of being uneven.

In addition, since the air is introduced into the device and immediately discharged after passing through the agricultural and marine products, the thermal efficiency is lowered. Therefore, energy is excessively consumed and the drying efficiency is low as compared with the dry amount of the agricultural and marine products.

However, the agricultural and marine products drying apparatus according to the present invention, by uniformly supplying and rapidly circulating the heated air to the drying chamber 100, it is possible to uniformly dry the agricultural and marine products, it is possible to maintain a constant quality of agricultural products. In addition, the optimum temperature and humidity can be adjusted by measuring the temperature and humidity inside the drying chamber 100, thereby enabling optimal drying. In addition, it is possible to shorten the drying time by using the far infrared rays, and to minimize the heat loss to reduce the energy required for drying the agricultural and aquatic products to reduce the drying processing cost.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Various modifications and variations are possible within the scope of the appended claims.
