VOLUME VARIABLE TENT TYPE FUMIGATION BOOTH OF FRUIT FUMIGATION FACILITY

摘要

The present invention relates to a variable-volume type fumigation booth used in a fruit fumigation facility. The variable-volume type fumigation booth varies the volume of the fumigation booth during a fumigation operation to enhance the fumigation efficiency and enables the fumigation gas to be easily diffused into a fruit box. Accordingly, the fruit fumigation facility includes: multiple fumigation booths (170) arranged in the facility (100); a chemical tank (10) storing a fruit fumigation agent; a vaporizer (30) heating the chemical liquid to heat and vaporize the liquid thereof; a fumigation gas supply line (50) supplying the fumigation gas vaporized in the vaporizer (30) into the fumigation booths (170); an air supply line (90-10) supplying air into the fumigation booths (170); and an exhaust line (110-1) discharging the fumigation gas to the outside of the facility (100) after the fumigation operation is completed. Each of the fumigation booths (170) includes: a closed and rectangular wall body (350) installed in the vertical direction; a sealing door (60) arranged on a side of the wall body (350); an elastic member (400) which is arranged on top of the wall body (350); an upper vertical member (310) fixed to the upper part of the wall body (350), a horizontal member (300) arranged on the upper part of the upper vertical member (310); and a horizontal lifting member (320) which is lifted along the upper vertical member (310).
