Meinecke Carrier Is
Revolutionary Says
Honolulu Advertiser

n SearDy shredder" is the comment
made by the Honolulu Advertiser up
on the intermediate carrier invented
by Joseph Meinecke of the M. A. Co.,
and in operation in the Paia mill and
several other large mills of the is
lands.
Relative to Joe Meinecke's in
vention the article says:
The Meinecke intermediate carri-
er is considered by sugar mill ex
perts the most revolutionary inven-
ton that has come out of Hawaii
since the invention of Searby's Shred
der n the Maesschaert system of
growing mill rollers. All the sugar
world looks to Hawaii for new ideas,
new methods, new records; in a word
II Hawaii adopts changes in practice
from field to refinery all the up-to-
date sugar producers in other lands
follow suit.
"Searby and Maeschaert's inven-
lions applied in conjunction with null
duplication of the three-roller units in
the modern mill train made 99.9 per
cent extraction possible. Mechanical
ly, there was nothing further to be
gained in that direction. But chemi-

tracted cane juices begins the instant
the last trace of sugar sap is pressed
out of the crushed cane matrix, so
thai in spite of mechanically perfect
extraction the sucrose delivered
from the mill to boiling house has
fallen short of total extraction.
Invention Reduces Loss
Joseph Meinecke, chief engineer
of Maui Agricultural's great modern
sugar mill at Paia, mulled over the
idea of taking up this wasted one, or
sometimes, in some mills, almost 2
per cent of sucrose that disappeared
from the juices in transit through the
mill between the first crushing unit
and the last.
The loss of sucrose through inver-
sion, which in the language of chem
lstry signifies souring or possibly the
change from crystallizable
cane sugar to other non-crystallizable
forms of sugars that are sweet, but
not salable over. the grocer's counter,
is very rapid. The rapidity of change
depends on aeration, or the amount
OF surface exposed to the air.
The intermediate carrier in SUI
gar milling parlance is the device,
whatever its form, that transfers the
partially extracted bagasse from each
three-roller unit in the mill train TO
the next. These intermediate carriers
nave given the engineers more trouble
IMAM any other part of the train. Wide
wooden Stats and narrow ones. NOV.
able steel plates, carrier chains,
sprocket and cog wheels, patent sides,
patent this and patent that, have been
used. Whatever the transfer deyice,
there has always been loss of bagasse
loss of sucruse in transit through
leakage and inversion.
Cuts Out Working Parts
"Meinecke has made a revolutionary
invention that throws all Of these in.
tricate devices into the scrap pile. His
intermediate carrier has no mechani
cal parts to break, clog or get out oil
order. 1t does not use up steam. II
delivers the bagasse from one mill tC
the next without loss or leakage and
with the minimum exposure TO the
air, thus reducing inversion through
aeration. It's simplicity of construc
ton is a notable feature.
1.-THE Meinecke carrier consists OF
nothing else but a trough made ol
steel plate, it's width the same as the
length Of the mill rollers. The side
plates are Of steel and a cover OF the
same material. The trough rises at ar
angle and then descends III a short
chute.
Uses No Steam
"The blanket of finely divided bag
asse discharged from the first mill is
forced up the long slope of the Gov
cred trough by back pressure. At the
top of the arch the expanded an(
loosened blanket is sprayed with the
maceration water and slides down by
gravity into the feed side of the mex
mill.
THAT is all there is to 1.-THE sim
plest possible contrivance-revolution
airy in it's effectiveness and simplicity
To facilitate handling, the carrier
trough is split at it's highest point
where a number of lifting holes per
NIT quick removal of the carrier wheI
it is necessary to get at other parts
of the mill.
1.-The feed chute is water-tight from
the point where the maceSation waite
is applied. Steel scraper plates will

way to the mill housings guard III,
discharge side of the mill where tn,
blanket enters the carrier. The re
moval of a few conveniently located
bolts permits lifting off The cove
plates to clean the carrier in the even
of long stoppages.
Widely Adopted
1.-The Meinecke intermediate carrie
was developed at Paia and is installed
in the 21-roller Maui Agricultural mill
1t is also in use at Waialua and Wal
luku, here and at San Carlos and Ca
lamba in the Philippines. Other in
stallations are to be made in Louis
lana, Cuba, Java, Formosa and Soutl
Africa.
simplicity, total absence of shafts

able, and breakable parts. cleanliness
and effectiveness, are the main point
that are going to put the Meinecke in
vention into every modern sugar mil
