crushed is to be operated with
small independent engine InsieaG cII
being driven from the mill.
In some places we are substituting
nickel steel shafts for iron or carbon
steel, especially on the top rollers.
AT three of our plantations we are
installing or having installed Richard
son Juice scales; so far they have
operated very successfully
AT one of our mills we are install
ing continuous lining system Tor
the 1912 crop.
AT Pepeekeo, in the past year, we
installed and had in operation Curing
the 1871 crop a continuous clarified
ton system which is fully described
by Mr.. Johnson in communication
to Mr. Deerr's committee.
I'VE have added excelsior filters in
some of our plants which are of spe-
cial design with removable basket
or container
AT Pahala several old tanks were
converted into excelsior filters.
The engineer at Pahala has de-
signed an excelsior washing machine
to be operated over the filters. IS
yet this is untried, and may be the
subject of a report next year
In several of our mills the old
juice heaters have been replaced with
larger heaters and the old heaters
utilized to preheat the juice entering
the eyaporator The fall in tempera-
ture Of the juice from the outlet OF
the juice heater to the evaporator is
usually from so deg. to 40 deg. F. The
preheating Of the juice before enter
ing the evaporatOr will contribute u
the capacity of the evaporator.
In several of our mills we are
replacing small filter presses with
large filter presses, the size of tqe
presses being 700 square feet each.
Smaller presses at present in use or
to be installed are expected to utilize
the old cloths from the large presses,
thus reducing the cost of filter press
cloth.
I'VE are installing a new type Of
Mountejuice for handling the muo
press juice and the washing out wafer.
Following a published suggestion,
we experimental with and demon
strated the advisability of the use o.
a system of washing out presses
which might be called a maceration
system, owing to it's resemblance to
the method of handling the water auc
| juices in the mills.
"A number of our evaporators We
have materially increased in capacit!
by the simple method OF admitting
the juice at the bottom OF the cells il
manner to increase the circulation
instead of at the ton or above the
calandria At Onomea an Arbucklt
sprinking device was installed in al
Of the cells of the evaporators; this
| device also showed a marked i'm
provement in the evaporation pei
square foot.
AT three of our plantations we
have or are installing central con
densers or notifications of the cen
/ trail condensation system. In one in
stance we have complete centra
condensing system without auxiliary
condensers. In other instances IN,
old condensers are still operated OF
the vacuum pans, and small vapo
pipes lead to a central condenser, n,
central condenser being used for al
the vapOr from the evaporators.
"A Leblanc air pump has been in
stalled during the past year in one 0
the pumping stations of the Oahr
Sugar Company, and was reported a
being very successful.
"At two of our plantations we ar,
installing new vacuum pans, the neat
ing surface being of the calandrIa o
express type.
in several of our sugar rooms W
are installing conyeyor machinery 20
handling raw sugar and bagged sugar
For the raw sugar underneath the cen
trifugals we have gone back to tn
old grasshopper type of conveyor.
AT two of our boiling houses ",
are installing crystaliaers, anG a
Pahala propose to use in addition [,
the crystalizers some old cooiin!
tanks arranged in piers.
I'm nearly all of our boiler house,
we are spending considerable none.
