In general, dryers that dry agricultural products such as rice, peppers, radishes, and onions, processed foods such as noodles, and marine products such as squid, flounder, and anchovies are divided into hot air dryers that use heated air and cooling dehumidifying dryers that dehumidify and dry indoor air.

A hot air dryer dries an object inside a drying room by introducing heated air, such as by a burner, into the drying room using a blower. However, there are problems such as discoloration or contamination of the object in the process of drying by high-temperature hot air, or deterioration of the quality of the object.

To improve this, as shown in Fig. 1, patent publication No. 10-2007-0108103 (title: cooling dehumidifying dryer) has been applied for. A conventional refrigeration dehumidifier comprises a first refrigeration system (10) having a first compressor (11) in which refrigerant is compressed, a first condenser (14) in which the refrigerant compressed in the first compressor (11) is condensed, a first expander (13) in which the refrigerant condensed from the first condenser (14) is expanded, a first evaporator (12) in which the refrigerant expanded through the first expander (13) is evaporated, and a first condenser fan (15) and a first evaporator fan (16) that allow internal air to flow for dehumidification and drying, a second compressor (21) in which refrigerant is compressed, a second condenser (22) in which the refrigerant compressed in the second compressor (21) is condensed, a second expander (23) in which the refrigerant condensed in the second condenser (22) is expanded, and a second expander (23) in which the refrigerant in the second expander (23) is It is composed of a second refrigeration system (20) having a second evaporator (24) in which expanded refrigerant evaporates, a drying room (30) in which a drying material is laminated and dried, and a circulation passage (40) that allows low-temperature dehumidified air generated by the first refrigeration system (10) and the second refrigeration system (20) to flow into the drying room (30).

The second condenser (22) of the second refrigeration system (20) is installed outside the drying room (30), and is used to maintain a low temperature inside the drying room.

The above first expander (13) and second expander (23) use conventional expansion valves.

The cooling dehumidifying dryer of the present invention, configured as described above, cools and dehumidifies the object to be dried inside the drying room (30) by introducing cooling and dehumidifying heat generated by the first refrigeration system (10) and the second refrigeration system (20) into the drying room (30).

In the process of drying the object to be dried inside the drying room (30) as described above, by directly using waste heat generated from the refrigeration system without using a heat medium such as a reheater, the object to be dried inside the drying room (30) is cooled and dehumidified, which is economically efficient and improves the drying rate and heat efficiency.

However, the conventional invention had a problem in that the air exhaust port was located at the top for optimal performance of the container-type dryer, so that hot air rose upward and cold air filled the bottom.

In addition, since the location of the temperature and humidity sensor could not be selected according to the type of agricultural and marine product, and environmental information inside the container could not be obtained, it became necessary to develop an optimal drying operation model for each agricultural and marine product.

In addition, it became necessary to develop an optimal efficiency model for each agricultural and marine product target and dryer size, and a proposal was made to enable the selection of optimal parts for a container-type dryer.

The present invention comprises a drying space (101) in which a drying object is located, a moisture removal unit (102) formed on one side of the drying space (101) to remove moisture from the drying object, an air heating unit (103) formed on an upper side of the drying space (101) to heat dry air from which moisture has been removed, and a dry heated air discharge unit (104) formed on the other side of the drying space (101) to discharge dried and heated air, and is characterized in that it controls using a control unit (180) according to temperature and humidity so as to maintain a comfortable environment and conditions for safe use within the drying device.

The above moisture removal unit (102) is characterized in that a duct (110), a dehumidifier (120), a hood (130), an outdoor dehumidifier unit (125), and an electric panel (140) are located on one side of the drying space unit (101).

The above air heating unit (103) is characterized by having a plurality of air intakes for sucking air on the upper side and a heater (150) for heating dry air.

The above-mentioned dry heated air discharge unit (104) is characterized by having a plurality of blowers (160).

The above drying space section (101), moisture removal section (102), air heating section (103), and drying heated air discharge section (104) are characterized by having a plurality of sensors (190).

The air discharge port of the duct (110) of the above moisture removal unit (102) is characterized by being located at the upper part of one side.
