A new pilot crystalliser for massecuite exhaustion trials

A new design of pilot crystalliser which has been developed for investigations into low grade massecuite exhaustion is described. Various cooling/reheating profiles can be selected using a programmable controller. Two units have been built as independent modules and include several features which provide good flexibility in undertaking exhaustion trials. The results of some investigations are presented including an assessment of the efficacy of pan additives on exhaustion performance.
