The present invention relates to a hot air type crop drying apparatus, and in particular, far infrared rays are radiated with higher efficiency to a crop that is dried at the same time as drying of the crop by hot air to obtain an excellent dry state of the crop, and the drying process. It is to recover the waste heat of the hot air is exhausted after performing the recycling of the recovered waste heat to increase the drying efficiency and to obtain the energy saving benefits supplied during drying.

Crops are cultivated plants such as grains or vegetables from rice fields, and some kinds of peppers, sesame seeds, etc. are dried in order to be realized as products. The crops are spread out to carry out the drying process.

Such natural drying requires a large space for drying the crops, and in particular, it requires a long drying time, so when drying the crops to be manufactured as a product, the productivity is very low, so that a dedicated drying device is used.

The basic form of the drying apparatus has a basic configuration consisting of a drying chamber into which the crops to be dried are put, and a hot air supply unit for supplying dry heat from one side of the drying chamber.

The drying chamber has a multi-stage tray configuration so that a plurality of trays on which crops are placed therein may be input, and the hot air supply unit heats the heater and the heat of the heater to supply heat into the drying chamber. It consists of a blower that advances the wind to circulate.

In addition, the drying chamber is formed with a discharge port for discharging after the hot air is circulated by the hot air supply unit, it is configured to include a door to open and close the entrance for opening and closing the plurality of trays.

The drying apparatus has the advantage of performing a quick drying process in a narrower space by stacking a plurality of fields on which the crops are placed in multiple stages inside the drying chamber and forcibly dried by a hot air supply.

In addition, the drying apparatus is coated on the surface or the inner surface of the crop on which the far-infrared radiant material which is beneficial for drying the crop, or by applying a far-infrared radiator to the hot air supply (construction to transfer the hot air of the far-infrared radiation heater and heater to the crop) to dry At the same time, it has been proposed to provide excellent dry conditions by supplying far infrared rays to crops.

When the far-infrared radiation composition is applied in the above-mentioned drying apparatus, since the far-infrared ray has the same characteristics as the light, the configuration of providing the far-infrared radiation heater to the hot air supply unit and transmitting the far-infrared ray by hot wind has almost no effect. In the case where the far-infrared material is coated in the interior space, there is a problem that an excessive expense of the coating cost and the inconvenience of the coating work are involved.

In addition, since the drying apparatus must always inhale fresh air from outside and heat it in order to generate and supply heat, the temperature of the heat generated by factors such as a change in external temperature conditions is not constant. As a result, the dry condition of the crop is slightly different each time the drying process is performed.

That is, it is difficult to always obtain a product dried in a high quality state by such a phenomenon, and if the heat generation amount of the heater is increased to obtain a good dry state, there is a problem of causing energy waste due to excessive power consumption.

The present invention has been invented to solve the above problems, so that the far infrared rays can be irradiated to the crops with high efficiency, so that the crops are dried in a more excellent state, recovering the waste heat of the hot air exhausted after performing the drying process, By circulating this to the point where the outside air is inhaled, an object of the present invention is to provide a drying device to reduce the high drying efficiency and energy consumption according to the preheating of the outside air.

In order to achieve the above object, the present invention has the following configuration.

The intake port 14 and the exhaust port 15 are formed on both sides, so that the intake air is collected after a predetermined amount is collected in the intake chamber 16, thereby providing a configuration for improving the intake efficiency.

In the figure, 16a is a through hole which communicates the intake chamber 16 and the inner space of the case 11.

In addition, the intake chamber 16 and the inside of the case 11 are communicated by the through-hole 17 formed in the case 11, the case 11 is the air inlet 14 and the exhaust port 15 to the outside air and hot air The hose 18 is configured to be provided to the intake / exhaust, it is natural that one or both sides of the door 19 for opening and closing the door 19 is installed to install the chamber housing 12 therein.

The chamber housing 12 has a plurality of through-holes are formed on both sides in order for the hot air introduced through the passage S to proceed to the crops, and a plurality of trays 13 on which the crops are placed are formed in a multi-layered combination. .

Here, a guide member 12a for sliding and coupling the both side edges of the cabinet 13 is installed on a plurality of layers on both inner surfaces of the chamber housing 12 in which the cabinet 13 is multi-layer coupled.

Although the guide member 12a is slightly different depending on the cross-sectional shape of both side edge portions of the tray 13, it is basically manufactured by bending the plate in the form of "b" or extruding metal, synthetic resin, or the like.

The hot air supply unit 20 is coupled to the upper surface of the drying chamber 10 is provided with a heater 21 formed of a far-infrared radiator therein, intake and heating the outside air to generate hot air and the generated hot air of the drying chamber 10 It is configured to supply to the passage S.

Specifically, the hot air supply unit 20 has a structure consisting of a frame 22, a blower 23, the heater 21.

The frame 22 is coupled to the outer surface of the case 11 of the drying chamber 10, and the inner and outer through holes 22a and 22b for re-suctioning the outside air and the outside air to be dried in the drying chamber 10. It is configured to form a supply passage (S1) for supplying the sucked outside air and hot air into the drying chamber (10).

The blower 23 is installed inside the frame 22 where hot air and outside air are sucked back, and is configured to advance the sucked hot air and outside air to the drying chamber 10, which is a cross flow fan inside the frame 22. Alternatively, any of the axial fans may be applied, which is accompanied by a motor driving device (generally not shown) for driving these fans.

The heater 21 is installed in the supply passage (S1) formed by the frame 22 is configured to heat the hot air and the outside air to the drying chamber 10, in particular in the form of an electric heater to the external power source The heating element that is supplied with the far-infrared radiator is configured to generate heat to radiate far-infrared rays and to be heated.

In the crop drying apparatus according to the present invention configured as described above, outside air flows through the blower 23 through the outer through hole 22b of the frame 22, and the air inside the drying chamber 10 passes through the inside through hole 22a. When introduced, the introduced air passes through the heater 21 and is generated as hot air to dry the crops located inside the chamber housing 12 of the drying chamber 10.

Thereafter, the hot air in which the drying process is performed is recovered through the inner through hole 22a of the frame 22, and part of the hot air is circulated back into the drying chamber 10, and part of the hot air is exhausted through the exhaust port 15. At this time, the exhausted hot air is heat-exchanged by the exhaust-side heat exchanger 41 and exhausted so that the refrigerant of the exhaust-side heat exchanger 41 is heated, and the heated refrigerant is transferred to the intake-side heat exchanger 42 to intake air. The outside air is heated to preheat.

At this time, the inside of the hot air is heat-exchanged to the outside and the outside air as much as the exhaust air flows through the inlet 14, which is omitted as a general air conditioner.
