FaNOn Bishop asked r. hopke TO eX'
plain in greater detail the Kopke cen.
trifugal carifer, the installation of
which at Koloa mill was mentioned in
the committee reports read Tuesday
afternoon.
Mr.. Kopke stated that the claims ad-
vanced as to the advantages of the new
method of Qualification were based on
observed facts and had not been caused
by brain-storms existing only in the
minds of the inventors. He reiterated
the statements made in the published
reports.
The machine is a cane juice clarifer
and is a modification of the Hapworth
type of sugar-drying centrifugal. The
experimental data thus far obtained
from the machines in operation show
entire saving of cost of filter cloth, the
saving of space in mill installation, and
the material saving in fuel and steam
requirements.
Considerable Saving.
The saving in steam arises from three
or more sources; (a) Che clarified juice
is delivered at a temperature thirty
degrees higher than that of filterpress
ed Juice ;(b) less water is used, and
to operate the evaporators; and, (c) as
ninety eight per cent of the juice is
clarified in the machine there are prac-
tically no scums.
1t takes only about half as much fuel
to clarity by the Kopke process as is
required by the flteI-press method.
Then there is saving in time; storage
tanks are not required; the Qualification

mill stops grinding; the mud is washed
and outside the building in very short
time; and, there is no loss from in
version OF sugars during the clarified
ton.
Its Mechanical Principle.
The machine depends in its mechani-
cal principles on the combination of
two well known laws of force-centrif-
ugal motion of particles in suspension,
in a revolving drum, and the weighing
actions of an ascending stream of IA
liquid on solid particles in suspension.
The former principle has long been
used in centrifugal separators, the
latter in gold quartz mills and i'm
proved starch machines.
Manager Renton, of Eva, then read
the report of the committee on labor
saving devices.
The Wilson, Webster cane loader was
tried out for q two weeks run ut
PuuDepe, The committee reports as
follows:
Wilson-Webster Loader.
"We believe that at the present
time the Wilson Webster Loader has
passed the experimental stage and that
machines can now be fabricated which
will employ features that have been
well tried out and found efficient
These machines with proper care and
attention can be depended upon to
give continuous and satisfactory ser
vice and will load cane utilizing a class
of labor unable to load in the way ac
complished by the japanese hand load
ers.
"The main point to be observed is
that with the improvements placed OF
the machine since last report, the rate
of loading on the best days work has
been increased to 25.5 tons per houl
for time actually spent loading anC
moving cars. This is an increase OF
AS tons cane per hohr over the best
days work last year.
''Your committee believes that tn,
Wilson Webster loader, as machine
has now been developed to very nea
its maximum degree of efficiency. 4
few minor alterations may be madt
but they will not add much to its ca
pacity. The greatest single factor u
increase the quantity loaded is the us'
of faring sides, or box cars such a
were used years ago at the Eva Plan
tation. With these ears a marked in
crease in the rate of loading can b.
effected.
"A complete set of tracngs of thi
loader with all improvements is in tn
possession of the committee, so that
should any plantation wish to utiliz
them at any future time, all details o
construction are available withou
further expense
Sugar in Blocks.
To illustrate new method of ship
ping raw sugars to refneres, compress
ed sample blocks of sugar were exhibit
ed. The advantages claimed are: tn
elimination of jute sugar bags; create
ease in handling; prevention of los
through breakage in transit; saving n
cargo space on vessels or cars; an
prevention of loss in polarization Q
sugars in transit.
The inventors of this process claim
cash saving of 81 ,600,0O0 on the shiI
ment of crop of 100000 tons. III
committee report continues;
"Your committee has undertaken
discover whether, under our preser
contracts, with the reineries, such
method of shipment would present an
features objectionable to them. Whe
THIS point is settled the matter wi
again be taken mp by the labor sayin
devices committee. The idea presen
ed in this method is certainly nov
aud interesting. In order to preseI
the objects which these gentlemen has
in view before this association, yol
committee has authorized Mr. !.
