Disclosed is an apparatus for drying agricultural products using far infrared rays. The apparatus for drying agricultural products using far infrared rays according to the present invention comprises: a housing formed to allow a worker to enter； a drying room which is installed inside the housing, which is spaced apart from an upper portion and a side surface portion of the housing at predetermined intervals, respectively, so that an air circulation passage is formed between the housing and the drying room, and which has a space for receiving a material to be dried； a heating unit which is installed on the air circulation passage so as to be positioned above the drying room, which radiates 0.891 or higher of far infrared rays at a frequency of 3-20 &mu；m, and which emits a radiation energy of 9.15 ×； 10^3 (W/m^2·；&mu；m) at 400°；C； a plurality of ventilation fans installed at one side of the drying room and provided to continuously circulate the warmed air from the heating unit through the air circulation passage and inside the drying room； and a dehumidifier installed on an outer surface of the housing to communicate with the air circulation passage and provided to remove moisture contained in the warmed air which circulates along the air circulation passage. According to the present invention, the warmed air heated by the far infrared rays is circulated on agricultural products to be dried, thereby completely and promptly drying even insides of the agricultural products, and thus increasing the drying efficiency, contributing to an effect of reducing energy through prompt drying and circulation of the warmed air, and eliminating the possibility of damaging the agricultural products.원적외선 농산물 건조 장치가 개시된다. 본 발명의 원적외선 농산물 건조 장치는, 작업자가 출입할 수 있도록 형성되는 하우징； 상기 하우징의 내부에 설치되되, 상기 하우징과의 사이에 공기의 순환통로를 형성하도록 상기 하우징의 상부와 측면부로부터 각각 일정거리 이격되어 형성되며 내부에 피건조물이 수납되는 공간이 마련되는 건조실； 상기 건조실의 상부에 위치하도록 상기 순환통로에 설치되며, 가열시 파장 3∼20㎛의 주파수에서 원적외선이 0.891 이상 방사되고 방사에너지가 400℃에서 9.15
