A complex fouling model based on a reaction/mass transfer scheme is coupled with a general thermal dynamic model of plate heat exchangers. All the important factors a!ecting milk heat treatment are formally quanti"ed. The "nal model comprises a set of partial di!erential, integral and algebraic equations. Parameter estimation analysis is performed based on the solution of a dynamic optimization problem. The simulation results are in a good agreement with available experimental work. Three di!erent con"gurations with complex #ow arrangements are considered to illustrate aspects of fouling behaviour. The simulation results provide signi"cant insight into the key factors a!ecting milk fouling. ( 2000 Elsevier Science Ltd. All rights reserved.
