Embodiment 1

[0021] as attached image 3 As shown in the accompanying drawing, only the feed end of the tunnel-type liquid nitrogen quick-freezing machine and the partial structure of the freezing chamber are drawn. The basic structure of the tunnel-type liquid nitrogen quick-freezing machine is basically consistent with the prior art. to perform. The tunnel-type liquid nitrogen quick-freezing machine includes a tunnel-type freezing chamber 8, and the two ends of the freezing chamber are respectively a feed end 9 and a discharge end, and a surrounding conveyor belt 1, which is located in the freezing chamber, and the conveyor belt 1 The two ends of the conveyor belt are respectively located outside the feeding end 8 and the discharging end of the freezing chamber. One end of the conveyor belt is set on the driving wheel, and the other end is set on the driven wheel so as to form an upper and lower conveyor belt in the freezing chamber. Inside the freezing chamber 8 There is a liquid nitro...

Abstract

The invention relates to a quick-freezing plant. Specific to the technical problems caused by the use of a conveying plate strip in a liquid nitrogen instant freezer, the invention provides an improved tunnel type liquid nitrogen instant freezer. The improved tunnel type liquid nitrogen instant freezer comprises a tunnel type freezing chamber and surrounding conveying belts in the freezing chamber, wherein support guide rails are arranged on the side walls of the freezing chamber between two layers of conveying belts; the support guide rails extend from the feeding end of the freezing chamber to the discharging end. The tunnel type liquid nitrogen instant freezer is characterized in that diffusion cavities along the freezing chamber are formed in the side walls, which are in contact with the support guide rails, of the freezing chamfer; the support guide rails are provided with a plurality of through holes for communicating cavities between upper and lower conveying belts with the diffusion cavities; a pipeline for communicating the diffusion cavities with the space above the upper layer conveying belt is arranged in the chamber wall of the freezing chamber; an exhaust fan is arranged on the pipeline. The improved tunnel type liquid nitrogen instant freezer is reasonable in structure, is easy and convenient to manufacture, and can be widely applied to the improvement of the conventional liquid nitrogen instant freezer.

Description

technical field [0001] The invention relates to a quick-freezing device, in particular to an improved tunnel-type liquid nitrogen quick-freezing machine. Background technique [0002] The applicant submitted a tunnel-type liquid nitrogen quick-freezing machine on December 4, 2014. The application number is: 201420750986.X. The tunnel-type liquid nitrogen quick-freezing machine mainly solves the problem of serious liquid nitrogen leakage and liquid nitrogen For the technical problem of high usage, the technical solution adopted is to be provided with a liquid nitrogen sealing device at the feeding end and the discharging end of the freezing chamber respectively; the liquid nitrogen sealing device includes a bellows arranged on the top of the conveyor belt, The top of the bellows is provided with an air inlet passage, and the bottom of the bellows is provided with a blowing outlet. The bellows is sealed and fixed with the top plate and the two side walls of the freezer. A blo...
