摘要
当前有两种简化的原则,可用于食品连续灭菌的设计。其一,假设所有流体都以管道中心的最大速度流动,并以之作为设计保持管长度的依据。其二,根据停留时间的平均值,以计算灭菌度,从而求出保持管的长度。本文采用这些简化的设计原则,针对拟塑性幂律型食品流体,提出食品连续灭菌设计的计算公式,用于幂律型非牛顿食品流体连续灭菌的工业设计。
Two simplified design rules have been used for the design and operation of continuous sterilisation process of food fluid. The first design rule assume that all the fluid was flowing at the maximum velocity of the center of a tube. The length of the holding tube can be calculated based on this rule. The second design rule is to calculate based on mean sterility from residence time distribution within the flowing fluid. This article presents related design calculation formulations of continuous food sterilisation for power-law non-Newtonian food fluid using above two design rules. These formulations can be used for industril design of continuous sterilisation for power-law non-Newtonian food fluid.
