pH Measurement Sugar Mill Carbonation Process - ABB
Sugar Mill Carbonation Process . Industry: Sugar refining . Sugar mill carbonation . After the mill crushes, shreds, or presses the cane or beets to extract juice, it adds calcium oxide (milk of lime). The calcium oxide raises the juice to 11pH or slightly more. The water in the juice reacts with the calcium oxide to form calcium hydroxide.
