The present invention relates to a hot air circulating crop drying apparatus, and in particular, to be irradiated with a higher thermal efficiency to the crops that are dried at the same time as the drying of the crops by hot air to obtain an excellent drying state of the crops, and performs the drying process While recovering the waste heat of the hot wind moving to the top of the drying chamber to recycle the recovered waste heat to increase the drying efficiency and to obtain the energy saving benefits supplied during drying.

In addition, by using the hot air circulatory crop drying apparatus of the present invention is dried evenly during drying to reduce the defective rate of the crop, the color of the crop is also maintained after drying to have a high commodity value, energy consumption is also reduced hot air cyclic crop drying Relates to a device.

Crops are cultivated plants such as grain or vegetables from rice fields. Some types of peppers, sesame seeds, radishes, and the like are dried in order to be realized as products. The crops to be dried are spread out to carry out the drying process.

However, the existing agricultural and aquatic product drying operation is carried out in the state laid out on the floor, so the space occupancy is considerably high, there are a number of problems, such as the continuous operation can not be carried out when the rain or strong winds blow.

In addition, the conventional drying method of drying the agricultural and marine products is because of the weakness of drying a large amount of agricultural and marine products in a limited time at a time, sometimes drying by heating with a dryer, so compared to the product grade and There is a problem that the quality and price are significantly lower.

In particular, when the pepper is heated or dried naturally as in the prior art, there is a fear of bacterial propagation, the color is also dried to a dark red color, there is a problem that the color is turbid when cooking and hot and sour taste.

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 been proposed a drying apparatus capable of performing a quick drying process in a narrower space by stacking a plurality of fields on which crops are placed in a multi-stage inside the drying chamber and forcibly dried by a hot air supply.

In order to generate and supply heat in the above-mentioned drying apparatus, the hot air supply unit always inhales new air from the outside and heats it. As a result, the dry condition of the crop is slightly different each time the drying process is performed.

In other words, it is difficult to always obtain the agricultural product dried in a good state by such a phenomenon, and if the calorific value of the heater is increased in order to obtain a good dry state, there is a problem that causes energy waste due to excessive power consumption.

The present invention has been invented to solve the above problems, so that the hot air to the crops can be irradiated to the crops with high efficiency evenly to dry the crops in a better state, and the waste heat of the hot air exhausted after performing the drying process It is an object of the present invention to provide a hot air circulating crop drying apparatus to reduce the high drying efficiency and energy consumption by recovering through a circulation suction pipe and circulating the same through the air in the drying chamber.

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