Abstract: The invention discloses a nozzle structure for a quick freezer, including a plurality of conical diversion channels, a plurality of jet channel, a plurality of hemispherical nozzles and a steel belt. The nozzle structure is a funnel-shaped structure formed by the conical diversion channel, the jet channel and the hemispherical nozzle. The nozzle structure of the present invention can effectively improve flow area at the cross-flow direction, and a fluid buffer area is formed between two adjacent nozzles, which can reduce the cross-flow effect, and improve the heat exchange rate of the surface of the steel belt, thereby reducing the freezing time of food, improving the freezing efficiency of the quick freezer, and reducing the energy consumption.
