| 摘 要： | 食品冻结时间的准确计算关系到食品冻结装置的优化设计及运行。本文提出了一种新的食品冻结时间计算方法，将冻结时间划分为三个阶段：冷却阶段、冻结和再降温阶段，并对各个阶段建立了动态计算模型。通过对有限长圆柱状食品的实验研究，将普朗克计算式与通过该模型计算得到的结果和实验数据进行比较，结果证明建立的计算模型是可靠的。

| Abstract: | Accurate calculation of freezing time of foods is important for optimum design and operation of a food freezer.Freezing time of foods is divided into three stages in this paper,which are pre-cooling time,freezing and super cooling times.Respectively dynamic calculation models are constructed for these three stages.Base on the studying of finite cyclical foodstuff,the models are proved to be advisable by comparing the calculating results with experimental data. |
