摘 要：
速冻是重要的食品保鲜技术之一,符合当代人们对绿色、方便、保健的三大要求,而速冻食品的品质与速冻设备的性能密切相关。本文首先介绍了速冻设备的分类和特点,综述了影响速冻设备性能的三个因素:能耗、气流分布和冻结时间,得出在速冻设备设计时也需综合考虑上述三个方面。在对食品冻结过程进行数值模拟时,应注意食品物性参数的时变性和建模的准确性,进而获得较为准确的数值计算结果。数值模拟和自动控制是今后速冻设备性能优化的有效手段。

摘 要：
Freezing is recognized as one of the most important technology in food preservation,which is in keeping with contemporary three requirements of green,convenience,health care,and the quality of frozen food is closely related to the performance of equipment.The classification and characteristics of the equipment were introduced,then the three factors affecting equipment performance,such as energy consumption,air distribution,and freezing time,were proposed,which were also needed to be considered for equipment design. The physical properties of time-varying and modeling accuracy of food( digital image) should be considered when the numerical simulation in food freezing process was carried out,to obtain a more accurate numerical results. Numerical simulation and optimization of automatic control are effective optimizing means of quick freezing equipment development.
