Make Illuminating Report
on Standard Methods

Valuable information on standard
practise in raw sugar manufacture is
given in a report made to A. Gartley,
chairman Of the planters association
committee on manufacturing ma
chinery, by E. Kopke and R Renton
Hind. This report, part of the series
under consideration at the annual
meeting of the planters, in an illumi-
native way measures the progress OF.
sugar production on the mechanical
side in Hawaii II is as follows:
Cane Scales: Nearly every factory
using railroad transportation Is
equipped with two sets of track scales
for weighing filled and empty cars
Few, however, of the scales are
equipped with what is known as regis
tering beam, and the adoption of this
device should eliminate many of the
errors which are bound to occur when
the recording of weights is left to the
weigher "=: ~
UnIoades: The adoption of the
Wick's unloader is becoming more
general, due to the fact that it is the
simplest form of unloading so far de-
vised, There is need for a device for
moving the mechanism from side to
side mechanically, for on the large
type of unloaders the handling of the
machine is only possible when the un,
loader man is of large stature. The
introduction of Filipino labor in our
mills means that the average cane
unloader man will not weigh more
than 40 or $50 pounds, making the
process of unloading a very difficult
task, and something is needed to make
its operation as easy as possible on
the operator.
kohala district on Hawaii have for
many years used iron Stats about one
eighth inch thick by seven and a guar.
ter inches or eight inches wide, for
the reason that they have found that
their life is great deal longer than
the usual wood slat Many planta-
tions, however, use a lbeyeled wood
Stat, which prevents the chopped
pieces of cane from failing through
the carrier after the cane has passed
through the revolving knives, but the
use Of the bevel slat makes it diff.
cult for the water from cane fumes,
to run off the cane carrier.
! Another feature in favor of the iron
Stat is the fact that the cane when
falling onto the carrier will in time
wear the wooden Stats unduly. From
time to time new types of cane car.
rier chain are being adopted, but the
old-fashioned chain using T bolts
when equipped with rollers seems to
be very efficient
Revolving Knives: The introduc.
ton of the Meinecke knife hub has
been a signal success in that it has
allowed the use of multiplicity of
knives which prepare the cane very
well for the mills.
They require considerable attention,
which, of course, is to be expected,
end the power required to drive them
is about 121a H. P. linear foot of cane
carrier width. Seven of these revolv.
ing knives have been furnished to Ha.
waiian mills by the Honolulu Iron
Works Company since their introduc.
ton within the last two years.
Carrier Clutches: The universal use
of the Moore clutch seems to prove
that this, type is meeting the needs
of the day.
Crushers: The Krajewski crusher
is fast giving way to the Fulton OF
grooved type, particularly with the
introduction of the multiple knife sets
and the Searby shredder, as it has
been found that the krajewski crush
er, while it breaks the cane up very
efficiently, extracts but very little OF
the juice. 49, ......:
Searby Shredder: The last two sea-
sons experience with this shredder
has shown that the most advantage
Gus position of it, in relation to the
other milling machinery, is between
the cane carrier and the subsequent
milling machinery In the 10 installa-
lions designed and sold by the Homo
lulu Iron Works Company, the fol-
lowing arrangement has been carried
out: The cane from the carrier is
cut by revolving knives and passes
through the shredder; from here it
passes on to the roller mills, or crush
er, if there is one. Four of these in
staIlations are for Formosa.
Mills: Owing to the Introduction
of the juice groove the need for the
incline type of housing is no longer
felt, as the pressures exerted upon
the top roller by the feed and dis
charge rollers can be very nearly
equalized Steel housings are replac.
ing housings made Of east iron almost
universally, for the reason that a sim
pier method of attaching the king
bolts is brought about by the use OF
steel, and the liability of housing
breakage is reduced to minimum.
