This utility model relates to a compressed air cooling system with a defrosting function. A high-temperature, high-pressure treated refrigerant is delivered to a defrosting channel via a compression module. The defrosting channel draws the refrigerant from the first cooling channel port of the second plate heat exchanger in the current defrosting mode for defrosting. The refrigerant then flows from the second cooling channel port of the second plate heat exchanger in the current defrosting mode to a return channel. The return channel delivers the refrigerant to a refrigeration module, which freeze-dries the refrigerant and delivers it to the second cooling channel port of the first plate heat exchanger. The refrigerant cools the air input into the cooled channel, and the cooled air is then output from the cooled channel to a set location. Simultaneously, the refrigerant is output from the first cooling channel port of the first plate heat exchanger and delivered to the compression module via a recovery channel. This utility model can improve the refrigeration efficiency of the refrigeration module and significantly save energy consumption.

This utility model discloses a tunnel-type liquid nitrogen quick-freezing device for preserving fresh wet noodles, relating to the field of liquid nitrogen quick-freezing technology. It includes a frame, on which a housing and a wire mesh conveyor mechanism are fixedly installed. The housing has an inlet and an outlet at both ends. A quick-freezing unit, a cleaning unit, a detection unit, and a recovery unit are fixedly installed inside the housing. The wire mesh conveyor mechanism passes through the inlet and outlet. The beneficial effect lies in the use of air-knife type nozzles in conjunction with honeycomb guide plates to rectify and evenly spray cold air containing liquid nitrogen. The flow direction of the cold air is changed by the baffles, allowing it to flow evenly around the product and efficiently cover it from both sides, significantly improving the freezing speed. The motor drives movable parts to flexibly adjust the nozzle angle, and the tilt sensor ensures precise angle adjustment, enabling the cold air to comprehensively and evenly cover products of different thicknesses, shapes, and heights, effectively improving freezing efficiency and quality.
