Assessing the efficiency of sucrose recovery from final molasses* [Full subscriber]

Abstract         The sucrose loss in final molasses is the largest loss in raw sugar manufacture and consequently requires consistent close monitoring in order to maximise raw-sugar production.  The main parameter used by the industry to assess the efficiency of recovery of sucrose in final molasses is the approach of the true purity of the final molasses to the Target Purity value, as defined in terms of the reducing sugars/ash ratio of the final molasses.  Another efficiency assessment can be obtained by comparing the actual sucrose loss in final molasses to that predicted based on the quantity of soluble impurities in…
