The present invention relates to a pressure-resistance type fruit fumigating and sterilizing facility, and the purpose of the present invention is to improve the efficiency of fumigation and sterilization by allowing a fumigation booth itself to withstand a high pressure and preventing the outflow of fumigation gas. In the present invention, the front, rear, left, and right lateral wall bodies, ceiling, and bottom of a fumigation booth (170) are all formed of a concrete wall (C), and an iron plate (S) is installed on the inside or outside of the concrete wall (C) in a sealing type, so the pressure of the fumigation booth (170) is not negative before fumigation and sterilization and the fumigation gas is directly sprayed to form and maintain a high pressure. A pressure control device (180) for controlling the internal pressure of the fumigation booth (170) and a thermo-hygrostat control unit (500) for supplying air with a predetermined temperature and humidity into the fumigation booth (170) when the fumigation gas is discharged after the fumigation and sterilization are completed, are provided outside the fumigation booth (170). A door device comprises: a sealing member (330) formed of a rubber material, and provided on four edges of a door (310) or the edge of an exit (H) and four inner surfaces of a pit (P) a plurality of first pushers (360) for pressing the door (310) toward the concrete wall (C) a lower sliding support unit (400) accommodated inside the pit (p) to allow the door (310) to glide and a sliding support unit (320) provided above the door (310) to allow the door (310) to slide.COPYRIGHT KIPO 2016본 발명은 내압형 과일 훈증소독 시설에 관한 것으로서, 훈증부스 자체가 고압에 견딜 수 있도록 하고 훈증가스가 외부로 유출되지 않도록 함으로써, 훈증소독의 효율을 향상시키는 데 그 목적이 있다.이를 위하여 본 발명은, 훈증부스(170)의 전후좌우 측면벽체, 천장 및 바닥이 모두 콘크리트 벽체(C)로 형성되고, 상기 콘크리트 벽체(C)의 안쪽 또는 바깥쪽에 철판(S)이 밀폐형으로 설치되어, 훈증소독 전에 훈증부스(170)의 압력을 부압으로 형성하지 않고 바로 훈증가스를 분사하여 고압을 형성 및 유지할 수 있고, 훈증부스(170)의 외부에는, 훈증부스(170) 내부의 압력을 조절하기 위한 압력조절장치(180)와, 훈증소독이 완료된 후 훈증가스를
