MILL EXTRACTION IN SUGAR MILL CALCULATION

Mill Extraction :-

 The quantity of sugar extracted in the mixed juice per 100 sugar in cane i.e. percentage of sugar extracted in the mixed juice out of total sugar in cane

 • Mill Extraction = Sugar (Pol) in M.J. % cane x 100 • Sugar (Pol) % cane

 

• Exam.(1) Cane = 9500 M.T. ;Mixed juice =9120 M.T.

 

• Added water = 2327.5

 

• Analysis of M.J.: – Bx. %juice - 15.5 , Pol %juice -13.02 

• Pol % bagasse -2.5 

• Calculate A.W. % cane, Pol % cane & Mill Extraction

 • Solution Cane + A.W. = M.J. + Bagasse 

• 9500 + 2327.5 = 9120 + Bagasse 

• Bagasse = 9500 + 2327.50 – 9120 

• = 2707.50 

 • Bagasse % cane= Total bagasse x 100/ cane crushed 

• = 2707.5 x10/ 9500

 • = 28.50 % 

 • M.J. % cane = Total M.J. x 100/ cane crushed 

• = 9120 x 100/ 9500 •

 • = 96.00 % 

• A.W. % cane = Total Added water x 100/ cane crushed 

 = 2327.50 x 100/ 9500 = 24.50 % Pol in M.J. % cane = Pol % M.J. % cane Mill Extraction =Pol in M.J. % cane x 100/ Pol % cane = 12.50 x 100/ 13.21 = 94.625 = 94.63
