There has been a steady increase in the uptake of continuous pan technology, as
opposed to the traditional batch pan alternative, when factory expansions are
undertaken. Many cxisting batch pans, however, retain the potential to give satisfactory
service over several decades before needing replacement. In some cases, relatively
minor modifications arc required to improve the performance of units to give acceptable
productivity, while retaining or improving sucrose recovery and sugar quality. With an
increasing emphasis on cogeneration of electric power in the future, pans will be
required to maintain these performance goals while minimising the consumption of
steam, and to use steam of lower pressures and temperatures. The paper divides the
problem of poor batch pan performance into factors pertaining to particular designs,
operational aspects, and the minimisation of non-productive time. Modifications and
operating procedures are recommended to maximise the potential of existing batch pans.
