OF USEFULNESS
Morning is Devoted to Hearing
and Debating Reports; Ban
quet VIII End Convention

! At the final session OF the sugar
mill engineers convention held this
morning three important subjects
were discussed by the members.
The paper on "Sugar Room Machin-
cry" by H. Keeling Scholefield,
opened by saying that:
"In following the tenets OF 'Scienti-
fic Management or Efficiency Engin-
eering,' as applied to any manufactur-
| ing business, an accurate knowledge
OF the expense attached to each opera
tion in the process becomes requisite
In an effort to evolve new mat
| ter for consideration, we have there
fore adopted the somewhat neglected
standpoint of costs "a table was
given showing comparative costs)
THE attainment OF any degree of
precision was so manifestly impos-
sible, In view Of the paHcity of segre-
gated records relative to the subject,
that the committee was only encour-
aged to proceed by consideration of
the fact that newly broken ground is
necessarily rough
The report then took up the Hersey
driver, concerning which II said: Con
sidering the matter apart from its
financial aspect. we have noted a
growing tendency to eliminate the
Hersey dryer. We also learned OF some
instances where automatic scales
have been discarded, the installation
at Waianae being case in point The
reasons for such action are no doubt
founded on experience"
In regard to the Hersey dryer, DIR.
Norris said that he believed that the
usefulness OF the dryer was now past.
At one time II was necessary but 9TH
er machinery has come in and with
the refiners objecting seriously to
the grade Of sugar sent from the Ha-
waiian islands other methods of dry
ing must be developed.
Objection to Hawaii Sugar
The main objection OF the refiners
ito Hawaiian sugar is the large amount
of dry molasses which sticks to the
crystals and Is extremely difficult to
remove.
McCubbin asked IL, by taking the
moisture out Of the air before using
It to dry the sugar instead of simply
heating the air, the moiasses would
not dry so hard on the crystals? Or,
in other words, using a dry air at a
lower tempe ature instead of hot air
for drying purposes.
In answer the general opinion was
that the heat had very little effect
towards making the mplasses, but 1t
was pointed out by Chairman Kopke
that the sugar men must pay more at
tention to this matter OF dried mo-
lasses on the sugar as he believed
that in the future contracts will also
take into consideration the cleanliness
of the crystals.
It was then pointed out that the
reason for the baked molasses was
simply that the moisture had been
removed.
Martin had method by which the |
refiners might remove the molasses,
saying that the refiners only need to |
let the sugar stand in the syrup mix
ture sufficiently long to loosen the mo-
lasses before applying 70 the centri-
fngals.
Tests and Records Needed
The next paper was, Testing and
Recording Instruments, and in TAX
ing up this subject, Kopke declared
that recording instruments were not
used sufficiently by the engineers and !.
that daily plotting charts should be
used by them all. Il have found that
the big interests are always ready to
install anything new when they can
be clearly shown that it is to their
advantage" he said, land advise
you all to prepare figures showing the
necessity of sHch instruments"
r. r. Hind said that when old ma
chinery is sold the money could be
placed in a fund to buy recording in
struments. This scheme was heartily
received by the engineers, and Kopke
said that the instruments were so ne
cessary that IL he was running the
scheme he would be sure to have plen-
ty of old machinery on hand.
The reports says:
at seems to be the opinion of all
those engineers who have any opinion
to express on the subject. that record
ing instruments are an extremely good
thing to have, and all would like to in
stall them If they could get them, but
such, unfortunately, is not always the
case
"The utility of recording instruments
lies not alone in the fact that they
keep q record Of operating conditions
at the different stations of the factory,
but In the moral effect on the man or
men whose work they record; the TACT
that an absolute check is being kept
on their work every minute Of the
day tends to make them toe the mark.
In this connection, il is generally con-
naand that tho hast mint To nlaca II
