Simulation of Liquid Food Processes in Modelica

Skoglund, Tomas LU (2003) In 3rd International Modelica Conference, November 3-4, 2003, Linköping
Abstract
Traditionally, liquid food processing equipment has

been designed and engineered from a static

perspective, where it has been taken for granted

that dynamic behaviour easily could be handled by

“add on” of control equipment such as sensors and

computers with control programs including control

loops. However, as production demands, e.g.

mixing accuracy, are escalated, this approach fails,

and the importance of simulating the dynamics of

the system becomes crucial. A tool that makes it

possible to minimise the cost and time for building

prototypes and making experiments would be of

Traditionally, liquid food processing equipment has

been designed and engineered from a static

that dynamic behaviour easily could be handled by

“add on” of control equipment such as sensors and

mixing accuracy, are escalated, this approach fails,

and the importance of simulating the dynamics of

the system becomes crucial. A tool that makes it

possible to minimise the cost and time for building

prototypes and making experiments would be of

considerable value, particularly if the tool enables

reuse of earlier work. Equally important is the

possibility to test various design ideas to improve

the equipment performance to en extent that

otherwise would not be conceivable.

This article describes how the Modelica based

tool Dymola1 has been used to build up a library

(“FoodProcessing”) primarily aiming at simulating

certain dynamic behaviour in liquid food

processing plants, particularly characterised by

incompressible fluids with complex rheologic

behaviour, transport delays and dynamically

changing concentration (Less)
