The present invention relates to an agricultural and marine product drying device of performing forward and reverse circulation of hot air through control of a wind direction, configured to improve drying quality of objects to be dried as heat of far-infrared and near-infrared rays is emitted inside a drying chamber, to equalize flow of hot air collected in the drying chamber by using a plurality of heat circulation fans installed in both sides of the drying chamber, and to circulate the heat in both directions according to predetermined control conditions so that the same temperature is formed in all spaces of the drying chamber. More specifically, the agricultural and marine product drying device comprises: a drying chamber (10) having a sealed storage space to accommodate a plurality of objects to be dried stacked in multiple layers; a middle layer panel (20) installed on an upper end of the drying chamber (10) and configured to distinguish boundaries of an upper layer and a lower layer of the storage space; heat supply units (30) installed at regular intervals on a central part of an upper surface of the middle layer panel (20) and configured to create a high-temperature environment on the upper layer of the storage space by using external power and waste heat; and a plurality of heat circulation fans (40) formed respectively on both wall surfaces of the storage space of the drying chamber (10), configured to circulate the high-temperature heat formed in the upper layer of the storage space, and allow for circulation of the heat by changing a direction of the circulation according to predetermined conditions. 본 발명은 건조실 내부에 원적외선 및 근적외선의 열기가 방출되어 피건조물의 건조 품질을 향상시키며, 건조실의 내부 양측에 설치된 복수의 열순환팬이 건조실 내부에 포집된 열풍의 흐름을 균등하게 하며, 기설정된 제어 조건에 따라 열기를 양방향으로 순환시켜 건조실의 모든 공간에 동일한 온도를 형성하는 풍향제어를 통한 열풍의 순환과 역순환이 이루어지는 농수산물건조장치에 관한 것으로, 더욱 상세하게는 다층으로 적층 적재된 복수의 피건조물을 수용하기 위해 밀폐된 적재공간을 갖는 건조실(10);과, 건조실(10)의 상단에 설치되어 적재공간의 상층과 하층의 경계를 구분하는 중층판넬(20);과, 중층판넬(20)의 상면 중심부에 일정한 간격으로 설치되며, 외부 전력과 폐열을 이용하여 적재공간의 상층에 고온의 환경을 조성하는 열공급부(30);와, 건조실(10)의 적재공간 양측 벽면에 각각 설치되어 적재공간 상층에 조성된 고온의 열기를 순환시키고, 기설정된 조건에 따라 순환 방향을 전환시켜 열의 순환이 이루어지게 하는 복수의 열순환팬(40);으로 구성되는 것을 특징으로 한다.
