High pressure processing uniformity

Boekbijdrage - Hoofdstuk

© Springer Science+Business Media New York 2016. As pressure is uniform and residence time is fixed, studying nonuniformity of high-pressure process variables comes down to studying temperature uniformity. This book chapter starts from the definition of adiabatic heat of compression to demonstrate that compression heat differences are a basis for the development of temperature heterogeneities in a high-pressure reactor. Since kinetics of change of target attributes of high pressure processing can be temperature dependent, temperature differences might result in process impact differences. There is a need for methods which enable insight in temperature gradients inside the high-pressure reactor. Since direct monitoring of the temperature as a function of time and space under pressure is today still a technical challenge at industrial scale, two alternative methods for temperature documentation under high-pressure conditions are described from principle to application. Finally, this chapter puts forward strategies to improve temperature uniformity under high-pressure processing conditions.
