Abstract To reduce energy cost and comply with recent European regulations, there is a growing interest for generic computer-aided tools to optimize energy consumption in food factories. There are several chemical engineering software but none dedicated to food processes. Prior to Pinch and exergy analysis, the entire process needs to be modelled, with specific constraints related to exergy analysis and scientific bottlenecks related to the estimation of thermophysical properties of food products and the modelling of unit operations specific to food processes. In this study, a generic methodology to model food processes to in fine allow Pinch and exergy analyses is proposed. The methodology was applied to the sugar beet process. The developed model allowed simulation of a real sugar beet factory, with deviation ranges within the uncertainties on industrial data.

使用化学工程软件 (ProSimPlus ® ) 对甜菜工厂进行模拟，以执行夹点和火用分析

摘要 为了降低能源成本并遵守最近的欧洲法规，人们对通用计算机辅助工具来优化食品工厂的能源消耗越来越感兴趣。有几种化学工程软件，但没有一个专门用于食品加工。在进行夹点和火用分析之前，需要对整个过程进行建模，其中包含与火用分析相关的特定约束以及与食品热物理特性估计和特定于食品过程的单元操作建模相关的科学瓶颈。在这项研究中，提出了一种通用方法来模拟食品过程，以进行精细的夹点和火用分析。该方法应用于甜菜过程。开发的模型允许模拟真实的甜菜工厂，
