Aquatic product cold-chain fresh-keeping cabin with temperature and humidity adjustment and fresh-keeping method

Abstract

The aquatic product cold-chain preservation cabin with temperature and humidity adjustment and the preservation method belong to the technical field of aquatic product cold-chain transportation and preservation, and comprise: the double-layer micro-porous flow guide wall is fixedly connected to the left and right side walls in the cabin body, the flow guide wall is composed of a solid baffle and a punched aluminum plate, and a static pressure cavity is arranged between the solid baffle and the punched aluminum plate; an evaporator is fixedly connected to the top of the cabin body, a variable frequency fan is fixed to the air inlet side of the evaporator, and a condensate water collecting groove is fixed directly below the evaporator, the bottom of the condensate water collecting groove is provided with a flow guide slot; a capillary evaporation net is clamped in the flow guide slot, the upper end of the capillary evaporation net is connected to the liquid water in the groove, and the lower end of the capillary evaporation net is flatly attached to the back of the punched aluminum plate; in addition, a phase change cold storage plate is fixed in the static pressure cavity and is arranged close to the inner side of the solid baffle; and a main control board is responsible for controlling the variable frequency fan and the compressor, the present application prevents the water loss of the aquatic products in the cold chain process, and simultaneously realizes the uniform distribution of the humidified cold air by means of the static pressure cavity and the punched aluminum plate, thereby significantly improving the preservation quality.
