Grain and molasses ratio calculation for ‘B’ continuous pan

In this article explain with example for B grain purity calculation with their required quantity of molasses. B continuous pan grain and molasses flow rate requirement according to the continuous pan capacity. Finally calculate B continuous pan massecuite dropping purity and its vapour requirement.

Data required for B massecuite purity calculation.

 S.No Particulars Brix Purity Specific Gravity 1 Syrup 60 82 1.276 2 AH molasses 75 71 1.337 4 Required B grain footing ( Before slurry feed) 86 75 1.435 5 B grain 88 ? 1.435 6 B grain batch pan capacity in metric ton(MT) 60 7 Graining Volume of the batch pan 45 % 8 Grain &  molasses ratio 1 3 9 B continuous pan capacity 30 T/hr 10 B massecuite Brix 95 ?

Calculation part :

B Grain material purity ( For B grain taken Syrup & AH molasses as a footing material and then further fill up with AH molasses.)
