Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] as attached figure 1 As shown, only the feed end 2 of the tunnel-type liquid nitrogen quick-freezing machine is drawn in the accompanying drawing. The basic structure of the tunnel-type liquid nitrogen quick-freezing machine is basically consistent with the prior art, and is not shown in the accompanying drawings. The tunnel-type liquid nitrogen quick-freezing machine includes a tunnel-type freezing chamber 1, and the two ends of the freezing chamber are the feeding end 2 and the discharging end respectively, and also includes a surrounding conveyor belt 3, which is located in the freezing chamber, and the conveyor network The two ends of the belt are respectively located outside the feeding end and the discharging end of the freezing chamber. One end of the conveying mesh belt is set on the driving wheel, and the other end is set on the driven w...

Abstract

The invention relates to a quick freezing device, in particular to a tunnel-type liquid nitrogenquick freezing machine, and solves the technical problems of serious liquid nitrogen leakage and high liquid nitrogen consumption of an existing liquid nitrogen quick freezing machine. The tunnel-type liquid nitrogen quick freezing machine comprises a tunnel-type freezing chamber and a surrounding-type conveying mesh belt in the freezing chamber, wherein liquid nitrogen plugging devices are arranged at the feeding end and discharging end of the freezing chamber respectively; each liquid nitrogen plugging device comprises an air box arranged at the top of the conveying mesh belt; an air inlet channel is formed in the top of the air box; an air blowing hole is formed in the bottom of the air box; the air box is hermetically fixed with a top plate and two side walls of the freezing chamber; an air inlet communicated with the air inlet channel of the air box is formed in the top plate of the freezing chamber; a fan is arranged on the air inlet; the width of the air blowing hole is the same as that of the freezing chamber; a material conveying hole is formed between the air blowing hole and the conveying mesh belt. Due to the adoption of the liquid nitrogen quick freezing machine, the liquid nitrogen consumption can be reduced by 40-50% and the quick freezing cost is greatly reduced in comparison with a liquid nitrogen quick freezing machine without the plugging devices.

Description

technical field [0001] The invention relates to a quick-freezing device, in particular to a tunnel-type liquid nitrogen quick-freezing machine. Background technique [0002] Since the boiling point of liquid nitrogen is -196°C, it is easy to vaporize, and it will absorb a lot of heat during the vaporization process, causing the surrounding temperature to drop sharply, so it is widely used in quick-freezing production. Taking quick-frozen prepared food as an example, the application of liquid nitrogen quick-freezing machine to quick-freeze and prepare food not only has a good quick-freezing effect, but also has a very high quick-freezing efficiency. The most common liquid nitrogen quick-freezing machine used for quick-freezing food is mainly tunnel type, such as application number: 201410254009.5, name: a liquid nitrogen freezing quick-freezing machine, application number: 201320253676.2, name: a tunnel type that can recover nitrogen Quick-freezing device, the common structu...
