Since the early history of beet sugar making,
it has been noticed that calcic salts render graining in the pan most
tedious; hence repeated efforts to reduce to a minimum percentage the
use of lime during defecation. In all cases it is essential to get rid
of inverted sugar. The difficulty from excess of lime is overcome by
adding it now and then during carbonatation; but other means are found
desirable; and phosphoric acid, magnesia, soda, etc., have been used
with success. Recent observations relating to the action of soda upon
calcic sulphates, calcic glucates, etc., are most important. Certain
citrates have a retarding influence upon calcic sulphates.
An alarm contrivance to announce the passage of juices into condensing
pipes has rendered considerable service in beet sugar factories.
A process for refining sugar in the factory, at less cost than it is
possible to make raw sugar by existing processes, deserves notice.
Sugars by this new method test 99.8, and sirups from the same have a
purity coefficient of 70.
