The utility model discloses a kind of frozen transport frames for cold storage ice plate, comprising: underframe, it is horizontally arranged, and the four corners position of lower end surface is all provided with universal wheel;Top frame, it is horizontally arranged above the underframe;Side frame, it is vertically arranged between the two sides of the underframe and the top frame;Tray, it is horizontally and layered arranged between a pair of side frame.The utility model has the following advantages and effects: by setting movable transport frame, the layered support of ice plate is realized, sufficient heat exchange space is ensured between ice plate, and it is convenient to push uniformly, the ice plate freezing speed of freezing out is fast, ice plate cannot be deformed, so that batch freezing and cold release operation are facilitated.

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.
