Raw sugar is made to a specified narrow purity range, and, therefore, the ratio of color-impurities in massecuite
and raw sugar determines the total amount of colorant in the raw sugar.
Under a partial vacuum, the clarified cane juice is boiled and rapidly evaporated until it forms massecuite
, a dense mass of thick syrup and crystals of raw sugar.
This pump is designed to operate primarily with massecuite
, magma and molasses, and the Flender unit was positioned with a Motox D181P geared motor on top of the gear unit.
The vacuum was then released and a fraction of the total "massecuite
" was centrifuged to yield the first crystal sample (mean size 0.5-0.6 mm).
