The drying chamber 10 is formed to have a duct 11 on both sides so as to be able to receive and dry agricultural and marine products. The duct 11 has a hot air flow path 12 for allowing hot air to flow into the drying chamber 10 through the air hole 13 so that hot air flows into the drying chamber 10. The through hole 13 may be formed on the side surface of the drying chamber 10 except for the door D so that the heat generated by the surface heating means 20 described later can be introduced into the drying chamber 10. The through hole 13 and the duct 11 forming the hot air flow path 12 may be provided on the lower surface of the drying chamber 10. When the through hole 13 is formed large, It is preferable that the through hole 13 is formed to have a small size. Of course, it is preferable that the face plate in which the through holes 13 are formed in the duct 11 for removing foreign substances is detachably used. Although not shown in the figure, the L-shaped bracket is attached to the duct 11 to fix the upper, lower, and side surfaces of the drying chamber 10. In addition, the drying chamber 10 may be provided with a fixing portion (not shown) protruding from the side surface for receiving and seizing agricultural and marine products, so that the tray can be seated or the agricultural and marine products can be mounted using strings on both sides.

The surface heat generating means 20 according to the present invention is accommodated in the duct 11 of the drying chamber 10 and supplies heat to the through holes 13 of the hot air flow path 12 to dry the agricultural and marine products. The surface heat generating means 20 radiates heat in a state of being formed in the duct 11 formed in the drying chamber 10 and intervenes with the machine chamber 30 to be described later to introduce heat into the inside of the drying chamber 10 . Such a configuration will be described later in detail.

The machine room 30 according to the present invention is provided with a blower 31 so as to communicate with the hot air flow path 12 in the vicinity of the drying room 10 to circulate the heat of the surface heat emitting means 20 into the drying room 10 And communicates with the waste heat flow path 32 to suck and recycle hot air circulated in the drying chamber 10 again. The machine room 30 is formed in proximity to the drying room 10 as described above. In the drawing, the drying room 10 is formed on both sides with the machine room 30 at the center. However, The drying chamber 10 may be formed on the other side. This is a structure that can be designed in accordance with the amount that the agricultural and marine products can be accommodated in the dryer. A blower 31 is formed in the machine room 30 so that air can be introduced into the drying chamber 10 through the blower 31 of the machine room 30 communicating with the hot air flow path 12, The heat of the one-sided heat generating means 20 flows into the inside of the drying chamber 10 to dry the agricultural and marine products. The machine room 30 is provided with a waste heat flow path 32 communicating with the drying chamber 10 so that the dried heat of the agricultural and marine products contained in the drying chamber 10 is circulated back to the machine room 30, And then flows into the drying chamber 10 to be circulated. At this time, a small number of electric heaters (not shown) may be further added and used together.

The controller 40 according to the present invention is electrically connected to the planar heating unit 20 and the blower 31 on the machine room 30 and controls the temperature and the air volume in accordance with the set sequence.

The surface heat generating means 20 includes a heat insulating material 21 for cutting off a high temperature which is emitted to the outside on one surface and a planar heat generating film 22 for generating heat to the inside of the drying chamber 10 close to the heat insulating material 21. [ And a heat conductive plate (23) having a thermal efficiency that is increased in proximity to the planar heat generating film (22). The surface heat generating means 20 is formed in the duct 11 of the drying chamber 10 so that the heat can be introduced into the drying chamber 10 through the through hole 13. Firstly, So that the heat inside the drying chamber 10 can be prevented from being discharged to the outside, thereby protecting the user from the outside. And a planar heat-generating film (22) that radiates heat near the heat insulator (21). Further, the heat conduction plate 23 is provided so as to increase the thermal efficiency in the vicinity of the planar heating film 22. That is, the heat insulating material 21, the surface heating film 22, and the heat conductive plate 23 are sequentially inserted and fixed on the inside of the duct 11 in the outward direction to allow hot air to flow into the drying chamber 10 to be.
