This technology relates to an agricultural and marine product drying apparatus designed to improve drying efficiency and reduce drying time. It features a greenhouse-type drying house equipped with drying nets where products are spread out for uniform drying via supplied hot air. The system circulates both the hot air and the heat transfer oil used as the heat source. The apparatus includes a greenhouse-type drying house with walls and a vinyl roof, divided into an upper drying section and a lower heating space by horizontally arranged drying nets; a radiator installed outside the drying house to supply hot air to the heating space; an impeller with a hot air circulation pipe connected to the radiator to circulate hot air in the drying section; a heat exchanger with a coiled heat transfer oil heating pipe connected to the radiator's inlet and outlet; a boiler with a burner connected to the heat exchanger to heat the oil; and a humid air exhaust pipe installed in the drying house to vent moist air.
Existing solutions in this field have faced structural and functional limitations that required improvement.
This technology can be applied to the agricultural and marine product drying industry to enhance performance and efficiency.
