MODELING, MONITORING AND CONTROL STRATEGIES FOR HIGH-TEMPERATURE SHORT-TIME PASTEURIZATION SYSTEMS - 1 - EMPIRICAL-MODEL DEVELOPMENT

Dynamic models of high temperature short time (HTST) pasteurization sy stems can be developed by using empirical model development paradigms such as transfer functions and times series models. Properly designed experiments that excite all output variables provide good data that en able the development of accurate dynamic models. These models are used in feedback control and statistical process monitoring system design. The methodology for time series model development for HTST pasteuriza tion processes is illustrated by using data collected from a pilot sca le HTST pasteurization system.
