Abstract:
Fouling of heat exchangers in the dairy industry has
been investigated extensively and a large number of studies
are reported in literature. This review focuses on the
mechanisms of milk fouling, detailing the role of protein
denaturation and aggregation reactions as well as mass
transfer. It has also been endeavoured to review the effect
of a number of different factors on milk fouling. These
factors have been divided into five major categories: milk
composition, operating conditions, heat exchanger
characteristics, presence of micro-organisms, and location
of fouling.
