A kind of lichee low temperature controlled atmosphere box, including box body, box cover and gas chamber, the box body and the box cover pass through setting
Buckle snapping on the box cover periphery；The side wall of the box body is equipped with hole slot, and the hole slot is used to connect the gas chamber side
Appendix on wall, the appendix are equipped with the cold-storage groove for loading refrigerating medium close to the bottom of the box body；On the appendix
It is additionally provided with gas control valve；The side wall opposite with the appendix of the gas chamber is movable side wall, in the movable side wall
Equipped with push rod, the cooling gas entered in the box body is adjusted by pushing push rod and adjusting gas control valve；The gas
Inflating port is additionally provided on room；Dismountable placement plate is equipped in the box body, if setting dried lychee hole position in the placement plate.
Further, the fitting surface of the box body and the box cover is equipped with sealing ring.
Further, the lichee hole position is half elliptic structure.
Further, lichee hole position bottom is equipped with chitosan/starch/glycerol/cinnamon essential oil composite membrane.
Further, the preferred PP materials of the movable side wall.
Further, the protective gas being filled in the gas chamber is according to the composition of weight percent：5%CO2, 3%O2,
92%N2。
Further, refrigerating medium is chilled brine in the cold-storage groove.
Further, the cold-storage groove inner wall and the box body outer wall are equipped with insulating layer.
Further, the preferred insulating foam of the insulating layer.
The beneficial effects of the utility model are：The utility model can push gas chamber by setting and be set on appendix
Cold-storage groove will be protected gas to be changed into after cooling gas and is transported in lichee storage box body using contraction principle and cooling principle, this
The fresh-keeping and cooling effect of mode is splendid, can effectively delay the brown stain of lichee, and the fresh keeping time of lichee is effectively extended to 1
A month.
