A model library for dynamic simulation of liquid food process lines
Tomas Skoglund, Petr Dejmck · Lund University Publications (Lund University) · 2006
Ongoing work in developing a general structure and a comprehensive components library aiming at modelling liquid-food process lines is presented. The dynamic component models were developed in an object-oriented library structure based on the dynamic modelling language Modelica using the object-oriented graphical tool Dymola. The models were based on fundamental conservation laws and can simulate one-dimensional dynamics in liquid-food plants including process control, in terms of flows, pressures, temperatures and compositions. Novel solutions were proposed to handle varying fluid properties during changeover in heat exchangers. Examples of simulations of cream and milk pasteurisation, juice blending and flash boiling for de-aeration of juice are given(1).
