Problems arising from the crushing of burned cane in sugar factories are discussed. Sugar loss occurs from the moment of harvest as sucrose in converted into reducing sugars and the purity of the cane juice decreases. The extent of inversion depends on juice pH, ambient temperature and the time between harvesting and milling. Juice from crushed inverted cane can cause problems with clarification, sugar boiling, crystallization and centrifuging. Gums in stale cane cause cloudiness in the juice, retard sedimentation in the clarifier and increase the mud volume. Dextrans occur in stale and burned cane, increasing the viscosity of syrup and massecuite and decreasing sucrose crystallization rate. Recommendations for crushing cane in order to optimize sugar recovery % cane are listed. Milling performance data are tabulated for operations with various percentages of burned and unburned cane. A mill testing report (tabulated indices of cane quality and juice extraction) for unburned vs. burned cane is also given.
