The present invention relates to a fumigation device of fresh fruits and vegetables using a fixed structure. The purpose of the present invention is to quickly diffuse fumigation gas by forming negative pressure in the inside of the fixed structure before the fumigation is executed and prevent the temperature of the inside of the fixed structure from increasing by the fumigation gas. To achieve the purpose, the present invention comprises a tetragonal fixed structure (170) having a sealed wall body and a roof a sealing door (60) which is formed on one side of the structure (170) a medicinal fluid tank (10) including a fumigant for sterilizing fresh fruits and vegetables an evaporator (30) which heats a medicinal fluid supplied from the medicinal fluid tank (10) and vaporizes the medicinal fluid a fumigation gas supply line (50) which supplies the fumigation gas vaporized in the evaporator (30) to the inner side of the structure (170) an air supply line (90-1) which supplies air to the inner side of the structure (170) and an exhaust line (110-1) which discharges the fumigation gas to the outside of the structure (170). The fumigation device of fresh fruits and vegetables additionally comprises a differential pressure gauge (190) which is formed outside the structure (170) and displays inside and outside pressure difference of the structure (170). A plurality of fumigation gas spraying nozzles (50-1) sprays the fumigation gas to the inside of the structure (170) after forming an inside pressure of the structure (170) with a negative pressure and is formed on the end of the air supply line (90-1). The fumigation gas spraying nozzles (50-1) is formed on one lower side of the structure (170) at each passage between loaded fresh fruits and vegetables boxes (290).COPYRIGHT KIPO 2014본 발명은 고정식 시설물을 이용한 청과물 훈증소독 장치에 관한 것으로서, 훈증소독을 실시하기 전에 시설물 내부를 부압 상태로 형성하여 훈증가스가 빠르게 확산되도록 하고, 훈증가스에 의해 시설물 내부의 온도가 상승하는 것을 방지하는 것을 목적으로 한다. 이를 위하여 본 발명은, 기밀성이 있는 벽체 및 지붕이 구비된 사각 형태의 고정식 시설물(17
