house at very limited outlay the plant can
be brought up to capacity Of 200 tons OF
dried sugar per twenty-four hours. The mill
proper is composed of three sets OF three
rollers each of 24X7S inches, and a set Of
two rollers forming the crusher, of 32x7s
inches, all directly driven from one large
single Corliss engine, with the necessary
gear. The boiler plant consists OF water
tubular Heine boilers and American econo'
mixers. The records achieved In this boiler
plant far surpass the expectations of the en-.
gineers who planned the construction. From
numerous tests that have been made TO as.
ct rtain the work which these boilers were
performing 1t was found that the Heine
tubular boiler was SURPRISING any Of the old
multi-tubular type by nearly rs per cent
In other words, the evaporation as shown
In these tests made on the several Heine
boilers installed in this plant has been
equal to the evaporation Of 3.4 pounds of
water to one pound of bagasse. equal to and
at temperature of 212 degrees Fahrenheit,
the bagasse showing an average percentage
OF from 80 to 40 per cent of moisture. with
about 3 1-2 to per cent OF sucrose therein
contained.
The contemplated horsepower for the re.
quired machinery of this size plant being
figured at 1900, there are six 250-horsepower
boilers In this plant. The working, how
ever, of the plant has been confined to five
boilers and sometimes but four. These
boilers have the Risdon Iron Works Com
