Evaluation of sucrose loss in evaporators for different processing configurations* [Full subscriber]

Abstract      The chemical compositions were determined for juice and condensate samples collected at various locations in the Robert evaporator sets at two Australian sugar factories. The purpose of the investigations was primarily to determine the magnitude of sucrose degradation and the consequences of those degradation reactions, such as reduced pH of condensate. Robert evaporators are used almost exclusively in Australian sugar factories. One of the factories involved in the trials incorporates a cogeneration facility and undertakes extensive vapour bleeding from large vessels at the first and second effects. The second factory undertakes no bleeding of vapour and the residence time…
