Sugar Room Machinery, Boil
ers and Furnaces Today's
Topic at Convention

4
Sugar Rccm Machinery and boil
ers and Furnaces were the topics OF
discussion at the Sugar Mil Engi-
neers' Convention this morning G.
White, chairman Of the committee Sc
iected 20 work up report on this sub
ject. was the principal speaker on SUI
gar room machinery. He spoke in
part as follows:
The centrifugal Is one OF the most
important and valuable machines we
have in the sugar mill and Is so well
known IA detail that any discussions
thereon. on the merits or demerits
| of different makes, need not be dwelt
upon here. Rather should we be oc.
lcupicd in getting the maximum output
of these machines. in kecping them az
their highest efficiency.
Thu spraying OF hot mllasses into
| the low grade massecuite when being
dried has been introduced into some
OF the mills and very decided gain
in the time OF drying has resulted.
AZ hiiauea, where this method was
employed during the last crop. tank
was erected above the centrifugal
into which the waste molasses was
pumped. This was then heated by a
steam coil to about 100 degrees Fab
lrenheit: pipe led from the tank into
each machine into which il was run
with the massecuite 10 be dried. This
gave us a saving OF % per cent in
the time of drying and also enabled us
TO boil per cent heavier, thus giving
lus consequently lower molasses and
bettery recovery, We propose fur
Their to increase the speed for drying
for the 1916 crop by the introduction
OF hot water pipes through the mixer.
heating the massecuite before 1t falls
into the machine.
Large Bins EssentIa.
Large bin capacity Is an essential
feature In a sugar room, where In
the majority of mills 1t can serve as
storage for sugar dried by the night
shift. and with the addition, perhaps.
of an automatic weighing machine,
and most certainly union sewing
machine, in conjunction with convey
ors to transport the bags to any part
of the room or cars.
sAt Kilauea, one man fills and
weighs. one woman at the, sewing ma
chine sews, and one man handles all
the bags as they fall from the con-
vey0r into the car. This crew can
