Sucrose losses across the Gledhow evaporators determined using NIRS predictions* [Full subscriber]

Abstract Shorter crushing seasons and reduced cane throughputs, as a result of the severe 2014 and 2015 drought, called for a concerted effort by the Gledhow sugar mill to optimise on sucrose recoveries for mill profitability. This proved to be challenging as the factory was not designed for lower throughputs, and led to general high Undetermined Losses (UDL); on occasion more than three times that acceptable for back-end refinery mills. A UDL audit verifying stock-take procedures, sugar movements and authenticating all known losses did not reveal the source of the losses. However, some losses across the evaporator station were identified…
