PROVISIONAL SPECIFICATION.
An Improved Method of Preserving the Sediment from Distilleries
for Use as a Sheep and Cattle Food.
I, JAMES MITCHELL, of No. 3 Douglas Terrace, Broughty Ferry, in the County of
Forfar, North Britain, Merchant do hereby declare the nature of this invention to be
as follows:-
This Invention relates to an improved method of preserving the sediment from
Distilleries for use as a Sheep and Cattle food.
In accordance with my Invention I take the ordinary sediment which is left
after distilling operations consisting for the most part of maize and I pump it into
a number of filter bags. After the water has drained off I put up the sediment
into cakes which I put in any suitable filter press; from the press, the water having
been driven out I put the cakes into a hot air chamber which is preferably built
in the form of a tunnel and in front of the cakes I mount a fan for the purpose
of drawing hot air through the cakes, the necessary heat to be imparted to the air
being preferably obtained by a series of hot air pipes around which the air is
caused to travel before passing through the cakes.
When the cakes are dried but before they become thoroughly hard, I put them
through any suitable chipping machine and I place the chips upon trays which I
arrange in proximity with the hot air pipes before referred to and when the chips
are thoroughly dried they are ready for the market.

I, JAMES MITCHELL, late of No. 3, Douglas Terrace, Broughty Ferry, in the
county of Forfar, North Britain, but now of Mardale Crescent, Edinburgh, in the
County of Midlothian, North Britain, Merchant, 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 :-
This Invention relates to an improved method of treating, for the purpose of
preserving, the sediment from distilleries for use as a sheep and cattle food.
According to my Invention I take the ordinary sediment which is left after distilling
operations, (consisting chiefly of maize,) and I pump or pass it into a number of filter
bags. This may be effected through a trough provided at bottom with outlets under
each of which a filter bag is situated. After the liquid or most of the liquid which can
be drained off by this means has drained off, I make the sediment into cakes which I put
in any suitable filter press; from the press, the most of the water having been
driven out. I put the cakes into a hot chamber, which can be heated in any suitable
way, as for instance by hot air or by steam, and which is preferably built in the
form of a tunnel, and I employ a fan for the purpose of drawing or forcing hot
air through the cakes, the necessary heat to be imparted to the air being preferably
obtained by a series of hot air or steam pipes around which the air is caused to
travel before passing through the cakes.
When the cakes are dried, but before they become thoroughly hard, I put them
through any suitable chipping machine, and I place the chips produced upon trays
or supports in the heating chamber, and when the chips are sufficiently dried they
are ready for use, for storage, or sale, for sheep or cattle food.
The accompanying drawing represents, in vertical section in Figure 1, and in
horizontal section in Figure 2, a drying apparatus suited for drying the cakes and
chips according to my invention.
Referring to Figures 1, and, 2. A, are the inlets by which the air to be heated is
admitted and passed through the chamber for drying the cakes and chips, B, are pipes
through which hot gases or steam are or is passed, so that the air as it passes over or
around them becomes heated or dry and thence passes through the compartment C, in
which are supported trays c, carrying chips made from the cakes. Beyond this is
another series of trays c³, carrying chips, and beyond these again is a compartment D,
containing racks on which the cakes which have been treated in the filter bags and
press as aforesaid are placed. E, E, are fans drawing in air by the inlets A, and
drawing it through the aforesaid compartments and then forcing it through the
compartment or compartments G, forming tunnels containing racks in which cakes
are held. After the cakes have been partially dried in the aforesaid racks, they are
removed and cut up or chipped as may be desired, or they may be passed through any
suitable chipping machine; after which process the chips are placed upon trays in the
drying apparatus and are dried, when they are ready for storage or sale.
The filtering bags may be of hair, cocoa nut fibre, cotton, flax, hemp, or other
suitable material, or mixtures thereof.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1st. The treatment for preservation of sediment from distilleries by filtering.
pressing into cakes and partial drying, then chipping and finally drying the chips
substantially as hereinbefore described.
2nd. In the treatment for preservation of sediment from distilleries the process of
drying in two stages, one whilst the sediment is in the form of cakes, and the other
after they have been divided or formed into chips substantially as hereinbefore
described.
3rd. The treatment for preservation of sediment from distilleries by filling into
filtering bags then forming into cakes and partially drying in an apparatus such as
shown in Figures 1, and 2, of the accompanying drawing, then chipping or dividing
as may be desired by any suitable means, and then drying the chips thus produced in
the apparatus shown in Figures 1, and 2, of the accompanying drawing.
Dated this 26th day of February 1889.
