the two mills the crushed cane usually re-
cetves a spray Of hot or cold water, vary
ing in quantity Of from to 20 per cent
OF the weight of the cane. This spraying
process Is termed masceration. the theory
being that water displaces the sugar, and
a larger amount Of sugar is thus extracted
from the cane. The juice from both mills
Is run into machine or tank specially con-
structed for sulphuring; that Is pa ssing the
fumes of sulphur di-oxide into the juice
Inc sulphuring process Is intended to
by precipitation. and to cause a larger pre-
cipitation to take place on the addition Of
lime which Is next to be added. il being
held that the larger precipitation of i'm
purities together with lime compounds the
greater the degree of Qualification or puri-
fication. The lime Is next added to the
juice while cold in large rectangular or cir
cular watts, steam Is turned on and the
juice is heated nearly to boiling by some
and boiled several minutes by others.
Heating causes a collection of the i'm
purities which usually form in a thick
scum on the top of the juice The scum is
prusheo ON and the juice allowed to set
tie The scum being passed through filters
the entire juice Is run into large settIinp
tanks in which during the course OF Tires
or TOUR hours the Impurities settle to the
oottom ana the clear juice Is passed by
gravity through bag filters, while in Others
only the Impurities or mud as they are
sometimes termed. are subjected to filter
ing; Ihe clear Juice Is usually of a slight
yeIoWish OF amber color If properly clari-
ned, or, II too much lime has been added
IL possesses reddish brown color which
color becomes more intense on further heat
ing. The clarified juice is then cooked in
open evaporators, or usually, In the up-to-
gate factory, in the heating apparatus
until 1t reaches the density of from 22'tn %
Beaume From these 1t is transferred to a
w oh &c,
very much decreased atmospheric pressure
The first syrup run Into the pan is q very
small quantity compared with the capacity
OF the vessel. and this small quantity Is
Withdrawn and spread upon a piece of
glass. The crystals now formed are in
tended to constitute the entire number OF
crystals for one strike, when the cooking
is completed, the object being to continue
running In syrup in the pan so that these
small crystals will grow. but not muJfinIy
until the desired size Is obtained. at which
time the pan should be as full as Is con-
ped out through an opening at the bottom.
which process is called strike From ths
pan the sugar which Is semi-solid In con-
sistency is transferred to the mixing ma
chine In which the sugar aud adhering mo-
lasses are very Intimately mixed. From,
the mixer the sugar Is taken to a CEN
trifugal machine, In which the moIasses Is
largely separated from the sugar by the
through small perforatIons In copper
cylinder. After few minutes In this ma
chine, making thousand or more reyolu-
tons per minute, water Is sprayed on the
the quantity OF water being regulated by
the quantity OF sugar desired II q high
grade sugar Is desired the spray Is applied
several times: II low grade only one or
TWO times The sugar Il then taken from
the centrifugal machine barreled and Is
ready for the market"
