摘　　要：射流冲击速冻是最先进的速冻技术之一,可以快速冻结食品并减少其组织损伤,从而提升食品冻结品质。但速冻设备性能极大影响射流冲击速冻过程,进而影响冻结食品的品质。因此优化速冻设备,完善射流冲击速冻系统对食品速冻行业的发展极其关键。论文首先对射流冲击速冻技术进行了概述;之后对现有文献中射流冲击速冻系统影响因素进行总结,包括喷嘴结构、喷嘴布置方式、雷诺数、无量纲射流对目标距离、传热共轭效应等;最后进行了总结和展望。Jet impact quick freezing is one of the most advanced quick freezing technologies,which can quickly freeze food and reduce its tissue damage,thereby improving the quality of frozen food.However,the performance of quick-freezing equipment greatly affects the jet impact quick-freezing process,which in turn affects the quality of frozen food.Therefore,optimizing the quickfreezing equipment and perfecting the jet impact quick-freezing system are extremely critical to the development of the food quickfreezing industry.This paper firstly summarizes the jet impact quick freezing technology;then summarizes the influence factors of the jet impact quick freezing system,including nozzle structure,nozzle arrangement,Reynolds number,dimensionless jet distance to the target and heat transfer conjugate effect;finally draws a conclusion.
