Digital twin-enabled process control in the food industry: proposal of a framework based on two case studies

Abstract

AbstractNowadays many processes in the food industry are monitored in an automatic way, with the purpose of minimising the need for workforce and of ensuring the proper control of the quality and safety of the foodstuff. All the sensors share data with a centralised management unit, where often a Manufacturing Execution System collects and evaluates them. As reported in recent research, however, a further step that can be undertaken, exploiting Industry 4.0 enabling technologies, is the implementation of digital twin approaches, with the additional aim to prevent possible issues during production. In line with these considerations, this work aims at showing two different digital twin models intended for improving the control of as many real food systems. Liquid and powder fluids are taken as examples for highlighting the differences in the optimization of the two food processes, as well as for fully exploring the potential of the digital twin approach. Finally, based on the real data taken from two pilot plants, a framework for the selection of the best digital twin tool in the food sector is delineated.KEYWORDS: Digital twinproduction planning and controlfood processesprocess controlIndustry 4.0 Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementData that support the findings of this study are available on request to the Corresponding author, prof.
