PROVISIONAL SPECIFICATION.
Means for Treating Spent Grains or other Analogous Material for
the Separation of Liquid therefrom.
We GEORGE THORNLEY and THOMAS BUXTON both of the Waterloo Engineering
Works Burton-on-Trent in the County of Stafford Engineers do hereby declare the
nature of this invention to be as follows:-
The object of our invention is to provide means whereby liquid is separated from
spent grain or other analogous material in a rapid efficient and economical manner.
According to our invention we subject the grain or other material to a double
process first a pressing process by which the principal amount of liquid is expressed
and then a drying process by which any desired quantity of the remaining moisture
is driven off.
For the pressing process we prefer to use a press of the description for which
Letters Patent have been granted to us dated the 18th day of October 1886
No. 13259 but with the perforated portions covered with a fabric in the case of
treating grains or other material which would otherwise be liable to be expelled
through the perforations. The subsequent drying operation we prefer to effect by
subjecting the grains or other materials which have been pressed to the action of a
current of heated air. The grains or the like may be discharged from the press into
carriers or onto an endless web by which they will be carried through a chamber
through which a current of heated air is passed and the extent of the drying can be
regulated by the speed with which the carriers pass or web passes through the drying
chamber. The dried grain or other material as it passes out of the drying chamber
may be discharged by falling or being scraped from the web or by tilting the
carriers or in any other suitable manner.

COMPLETE SPECIFICATION.
Means for Treating Spent Grains or other Analogous Material for
the Separation of Liquid therefrom.
We, GEORGE THORNLEY, and THOMAS BUXTON, both of the Waterloo Engineering
Works, Burton on Trent, in the County of Stafford, Engineers, do hereby declare the
nature of this invention 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 our invention is to provide means whereby liquid is separated from
spent grain or other analogous material in a rapid efficient and economical manner.
According to our invention we subject the grain or the like to a double process
first a pressing process by which the principal amount of liquid is expressed and then
a drying process by which any desired quantity of the remaining moisture is
driven off.
For the pressing process we prefer to use a press of the description for which
Letters Patent have been granted to us dated the 18th day of October 1886
No. 13259 but with the perforated portions covered with a fabric as in treating
grains or analogous material they would otherwise be liable to be expelled through
the perforations. The subsequent drying operation may be effected in any suitable
known description of drying apparatus. As drying apparatus in itself constitutes
no part of our present invention it is unnecessary to describe or illustrate such
Rin 177

page_text: apparatus; but we may state generally that we prefer to effect the drying by sub-
jecting the grains or analogous materials which have been pressed to the action of a
current of air or by passing them through a heated chamber." The grains or the like
may be discharged from the press into carriers or on to an endless web by which
they will be carried through the heated chamber or through a chamber through
which a current of air is passed and the extent of the drying can be regulated by
the speed with which the carriers pass or web passes through the drying chamber.
The air passed into the drying chamber may be either previously heated or not.
If it be not previously heated and be admitted to the drying chamber at the part
at which the grains or the like are discharged it becomes heated as it passes over the
hot grains or the like towards the part where the said grains or the like are admitted.
Drying apparatus such as is known as Milburn's drying machine is suitable for the
purposes of this invention but we do not limit ourselves to the use of any one
particular kind of machine. The dried grains or the like as it passes out of the
drying chamber may be discharged by falling or being scraped from the web or by
tilting the carriers or in any other suitable manner.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The separation of liquid from grains or analogous materials by subjecting them to a
double process consisting firstly of pressing the grains or materials to express moisture
and then subjecting them to an air drying operation substantially as hereinbefore
described.
2. In or for the separation of liquid from grains or analogous materials the use
of a press such as is described and having the perforations through which the liquid
is expelled covered with a fabric substantially as and for the purpose hereinbefore
described.
