for settling; then the clear juice is dra wn
off and the skimmings go through the filter
presses.
This is indeed a very simple operation.
and gives a god Qualification, at least
in Cuba, where they have to handle juice
Of 80 purity but it is rot advisable to adopt
that method here with cur poor juice Of rs or
so purity.
A triple and a quadruple effect evaporated
the juice into syrup. Three vacuum pans Of
different sizes are boiling first and second
sugars and molasses.
Average cane analysis shows 21.4 Brix,
1880 per cent. sucrose, . per cent. glucose,
90.2 purity, 1872 per cent fibre.
Two hundred and eighty pounds Of COM
mercial sugar could be made from every ton of
this excellent cane, but | do not think that
the average is more than 230.
Factory C-Capacity 400 tons Of cane per
"a hours:
Two separate mills, each consisting of two
three-roller mills, do the grinding.
Neither lime nor sulphur is used the
Qualification is done by addition of baryta, a
new patented process. From the CHARTERS
the Juice runs through mechanical filters
the skimmings 90 through filter presses. A
triple and q quadruple effect do the evap-
Grating. Two vacuum pans, one Is feet diam.
the other IL feet diam. do the boiling. A
battery of centrifugals separate the sugar from
the syrup.
Only first sugar is made; the syrup which
runs from the first sugar is used to macerate
the bagasse between the first and second mills;
it gets that way mixed with the fresh mill
iuice and is worked over and over again.
This process may have it's advantages and it
may produce less molasses than the ordinary
process, but it is impossible to make sugar
without producing any molasses. In the or
binary way a ton Of cane gives nine gallons
of syrup run off from first sugar. Let us take
it for granted that this new process is really
capable Of increasing the yield OF sugar from
the first maSse cutie to such an extent that
only four gallons Of syrup would be left per
ton of cane. In that case this factory would
produce every day $500 gallons Of syrup, OF in
nineteen days 504,0 600 gallons. The writer
if this was told that for three months no
syrup. no second sugar, no molasses had
been made. Now, then, where are these 3O4,
600 gallons Of syrup.

Two d illusion batteries are in operation

Lime is added in the cells; he juice runs

me how much.
Different systems Of boilers are IN operation,
with, together, 1900 horsepower.
The evaporating apartment contains two
triple effects, one quadruple effect and four
vacuum pans. Besides these apparatus there
is a Yaryan triple effect, but it is not all the
time IN operation.

sugar wasted on the floor. 1t was a gorgeous
