Abstract
Dextrose is crystallized from an impure liquor to which dextrose sodium chloride has been added. A process is described in which an initial dextrose liquor is evaporated to about 40 DEG B<\>ae., cooled to about 120 DEG F. and run into a warmed crystallizer where its temperature during the first three days falls to about 110 DEG F., and then to about 93 to 95 DEG F. during the next three or four days. After centrifuging, the crystals are dried and crushed, the wash water being returned to the initial liquor. The centrifugal liquor is treated with acid to complete its conversion into dextrose, decolourized and mixed with an aqueous solution of dextrose sodium chloride, the proportions being about 70 lb. of the double salt to 100 lb. of the dry dextrose. After concentration, the liquor is evaporated and crystallized over about 6 to 8 days and centrifuged, the dextrose being either mixed with the first batch or dissolved and mixed with the initial liquor. The liquor from the second centrifuging is used for the preparation of dextrose sodium chloride.ALSO:Dextrose is crystallized from an impure liquor to which dextrose sodium chloride has been added.
