IMPROVEMENTS IN THE PROCESS OF AND APPARATUS FOR TREATING MEGASS FOR EXTRACTING SUGAR THEREFROM
Year: 1884

page_text: I GEORGE WILLIAM PARBURY, of 7 East India Avenue, Leadenhall Street in
the City of London, Merchant, do hereby declare the nature of the said Invention
for IMPROVEMENTS IN THE PROCESS OF AND APPARATUS FOR TREATING MEGASS
FOR EXTRACTING SUGAR THEREFROM (a communication to me from abroad by
Gustav Kottmann of Sydney, New South Wales, Chemist) and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
-
The object of this Invention is to extract by means of diffusion the sugar
contained in the megass or crushed sugar cane as it leaves the mill; and a patent
is claimed for the apparatus hereinafter described, and generally, for the practical
application of the principle of diffusion to the treatment of megass.
The apparatus in question is designed to receive the megass immediately on its
leaving the mill or after it has been shredded, torn, or cut into small portions in
a shredding, tearing or cutting machine preparatory to its entrance into the diffusion
apparatus; and when so received it is gradually passed through a current of
boiling water whose course is contrary to that of the megass and finally emerges
at a point where it is conducted into another mill in which it is again pressed and
then used as fuel in the ordinary way.
The following description will explain the mode of working reference being had
to the accompanying drawing in which A is a vessel of cylindrical or other
convenient shape made of iron or copper, having water tight sides and bottom, and
of a size proportional to that of the mills to which it is to be attached. In this
vessel a drum B made of iron or other metal is revolved by a worm and worm-
wheel or other suitable gear, and having glands or other means of preventing the
escape of the water contained in the annular space between the drum B and the
circumference of the vessel A. In this drum are set arms or teeth at convenient
distances and angles, and the megass in falling into the apparatus from the
elevator C. (having previously passed through the shredding, tearing, or cutting
machine E, or having only passed through the mill D) is, as the drum B revolves,

various distributing pipes marked F, convey water of whatever temperature is
found necessary for the diffusion of the megass, the temperature being maintained
by jets of high pressure steam led into the bottom of the apparatus through pipe O.
and nozzles 1, 2, 3, 4, 5, 6; or by other suitable means. When the megass reaches
the point marked G. it is thrown off the drum B by the wheel H. which is provided
with arms of the requisite length and number, and it thus falls into the other
mill J. where the moisture in the fibre is expressed in the usual manner, the megass
then being used as fuel. The water put into the apparatus at F filters through
the megass in a direction opposite to the revolution of the drum B. and is drawn off
at point K, whence it is taken into the factory for treatment.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
1st The combination of parts constituting the improved apparatus for treating
megass to extract sugar therefrom; constructed, arranged, and operating as shown
and described in the drawing hereto annexed.
2nd The application of the principle of diffusion by means of the apparatus
above described to the treatment of megass (either in the condition in which it
leaves the mill, or after it has been shredded, torn or cut into fragments in a
machine designed for this purpose) with the object of extracting the sugar retained
therein; the megass being caused to traverse an annular space in opposition to a
stream of heated water, and, by a continuous action, ultimately to be expelled and
guided into another mill where it is finally crushed, the resultant sweet water being
drawn off and taken to the factory for treatment.
