The uses of fouling models in the design of food process plant

The problems caused by fouling are outlined, and recent work to understand the processes of fouling reviewed. Fouling is a two-stage process: the reactions governing the first stage are unclear, but the second stage appears to be governed by protein aggregation in the bulk fluid. The use of a computer model for fouling in simulating heat exchanger behaviour is described: it is possible to select an exchanger with an optimal fouling response. The need for accurate fouling and cleaning kinetics is stressed, and the role of a process monitor outlined.
