The difference of the increased fiber
content in the cane will be found in
tual practice 10 have a greater effect in
preventing the extraction of the juice
than that given in the above table.
"In Louisiana, the difference between
10 per cent and u per cent of fiber in the
cane reduces it's value 6 per cent from
an extraction point of view.
ia. Planter Nov. "A. 1900
1t will be apparent that a mill grinding
cane containing Is per cent sugar and
13 per cent fiber, and obtaining ex-
traction of 1918 per cent will be doing
better work than a mill grinding cane of
.dG per cent sugar and 10 per cent fiber
and obtaining an extraction of 1925 per
cent.
Maceration.-The advantages of mace
ration in the extraction OF sugar from
the cane are now recognized in all sugar
cane countries, but this system is not
yet used to such an extent in these ISL
ands as at the Colonial Sugar Refinery
Company's estates in Fiji and Queens
land.
In all cases where the juice approx
mates a purity of 80 per cent n dilution
of from 10 to 10 per cent may be used to
advantage, and if the sucrose content of
the cane is high, q dilution of from 20
10 % per cent will be found profitable.
provided the bagasse furnishes sufficient
fuel for the requirements of the factory.
If water not exceeding a temperature of
165 +. be used. the greater part of the
impurities extracted by the maceration
water will be removed In clarifying.
Intrusion Tho il NOT
popular as means of extracting sugar
from cane on account of the cost of
fuel, and also because the long exposure
of the cane to water of high temperature
extracts more than by the milling proc
ess, of the pectinous (gums) and nitro
genous substances (amids) which can
not be removed by the ordinary proc
esses of Qualification. and consequently
interfere with the recovery of the sugar;
this is more noticeable in canes having
juices OF low purity.
Clarification.-The Deming system is
now most in favor with planters making
sugar for refineries. Mr.. Prinsen Geer-
ligs of Java says of experimenting:
From a chemical point of views super
heat Qualification stands in no respects
behind the usual DELEGATION process,
whilst its mechanical advantages are
many
Evaporation.-The concentration of the
should be performed as rapidly as possi-
BILE, and this is now accomplished in
modern factories by means of the Lille
Evaporators.
Filtration.-As much or the impurities
are precipitated in concentrating the
juice filtering the syrup. particularly if
the juice has been superheated, would be
of advantage as 1t would remove many
of these impurities.
Observation-Disclosures order to get the
best results from impure juices in boiling
to grain, the vacuum pan should have
ample heating surface, well distributed,
so that "the circulation is systematized
from the peripheral extremities toward
the center, whereby the essential mo-
mentum of circulation can be establish
ed.
CrystalIizers are now in use in several
factories in these Islands a report
work accomplished by Mr.. Johnson,
chemist for the Waialua Agricultural
Company.
A report of the Investigations of Mr..
Princen Geerligs In Java on crystalllzer
work has already been brought TO your
attention by Mr.. Geo. Ross in the Sep
TENDER number of the Planters Month
ly.
Drying Sugars.-water driven centrifu-
gals are growing In favor. and have
many advantages over the belt driven
machines. Granulators are used only in
few factories.
Preservation of Sugar in Storage or
Transit.-Cleanliness in all departments,
careful Qualification of the juice and
watchfulness to prevent incipient fer
mentation in the sugar house. this and
careful drying of the sugar before pack
ing. Will usually be found sufficient to
prevent deterioration. It has been sug-
gested TO disinfect the packing material
and 10 protect the sugar much as pos
sible from moisture by suitable covering,
when stored or in transit 1t has been
found that the alkaiinity of sugar does
not affect its keeping qualities.
Utilization Of Waste Products.-The
value of press cake as a fertilizer has al
ready been brought to your attention in
the report on Manufacture of 1899.
Bagasse as Fuel.-Excellent results
have been obtained by burning the ba
gasse in furnaces of the Dutch oven
type, having step ladder CRATE bars. The
mills as compared with good coal is as
follows;
334 tons of baeasse containing A 20
per cent moisture equals one ton of coal.
Az tons OF baessSe containing 81 per
cent of moisture. equals one ton of coal
''Mr. Hubert Edison of Louisiana pro
poses to use the heat OF the chimney
gases to dry the basssse before using.
and in this way effect a saving of Is
per cent in its fuel value.
The process OF making paper from bA-
gssse at large mill in Texas IS de-
scribed in the Louisiana Planter of Oc-
tober ;: Eight million pounds OF paper
were made from 10000. 900 pounds of ba
gasse. The paper sells at cents per
pound, making the value of this product
Sl5o, eco The cost of manufacture is not
given, but that it pays is shown by the
fact that mills in Louisiana will shortly
add this branch OF manufacture to their
establishments"
The day may not be far distant when !
sugar VIII be shipped in containers made F.!
from bagaSse and having greater
strength than those now used, and with /!
air and water proof qualities.
