PURPOSE: A quick freezing tray, a tray stacking frame having the same, and a quick freezing device are provided to quickly cool a target freezing body by passing the cool air through a tray stacking frame at a high speed with pressure differences between the tray stacking frame and a quick freezing chamber. CONSTITUTION: A quick freezing tray(100) comprises a bottom surface(110) and side walls(120). A target freezing body is mounted on the bottom surface. Inlets(112) are perforated on the bottom surface to inject cool air in an opposite direction of the gravity. The side walls are upwardly bent along a circumference of the bottom surface. Outlets(122) are perforated in one of the side walls to discharge the cool air injected from the inlets. The inlets are punched as a tapered shape. The diameter of the inlets formed in an outer surface of the quick freezing tray is larger than the diameter of the inlets formed in an inner surface of the quick freezing tray. |
