Abstract
The Steffen's process for the recovery of sugar from beet molasses consists of a cold and a hot precipitation. The molasses has a specific gravity of about 1.3 and a sucrose content of approximately 50 per cent. It is diluted with water until it has a specific gravity of about 1.05, and contains 5 to 6 per cent of sucrose. To this solution cooled to 15°C, powdered lime is added, with agitation, in the proportion of one part calcium oxide to one part sucrose. In the cold precipitation process, insoluble tri-calcium saccharate is precipitated.
