PROVISIONAL SPECIFICATION.
A New or Improved Method for the Disposal of Distillers' or Brewers'
Refuse.
We, GEORGE SOUTER and JAMES STEPHEN SOUTER, both of Greyfriars Foundry,
Elgin, Elginshire, Engineers, do hereby declare the nature of this invention to
be as follows:-
This invention has for its object the disposal of burnt ale, spent lees, and similar
waste liquids from distilleries and breweries, by means of evaporation by steam,
and thereby prevent the pollution of streams and rivers.
The apparatus used for this purpose would be similar to a marine evaporator,
in which the steam for evaporating is admitted into a number of coiled tubes
which are placed inside a closed vessel for containing said liquids. The condensed
steam is let out by a steam trap and may be utilised as feed water for the boiler.
The said vessel would have a space or chamber at the bottom for receiving the
sediment, which could be blown out under pressure of the steam generated by
evaporation. The said steam could also be applied to ordinary purposes for which
steam is used.
If desired the moisture may be further removed from the sediment by drying
on a kiln, or in a hot chamber.
The evaporator would be fitted with steam and water gauges necessary for
maintaining the proper working conditions.
A force pump would be used for keeping a constant level of liquid in evaporator.

COMPLETE SPECIFICATION.
A New or Improved Method for the Disposal of Distillers' or Brewers'
Refuse.
We, GEORGE SOUTER and JAMES STEPHEN SOUTER, both of Greyfriars Foundry,
Elgin, N.B., Engineers, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention has for its object the disposal of burnt ale and spent lees, and
similar waste liquids from distilleries and breweries by means of evaporation by
steam, thereby avoiding the pollution of streams and rivers. The apparatus

page_text: used for this purpose is similar to a marine evaporator in which the steam
for evaporating is admitted into a number of coiled pipes, placed inside
a closed vessel for containing the said liquid. These liquids not being required
to enter pipes while under treatment, choking by the adhesive residue of the burnt
ale is avoided. The evaporators used may be worked either on the simple or
compound principle, that is to say, the steam generated from evaporation of the
liquid refuse may either be taken directly from the evaporator for any special
purpose or be passed into the coils of a second evaporator. In order to evaporate
the liquids with the utmost economy, we utilize the waste heat from the stills
while it passes from the still flues, which are of any ordinary construction, on its
way to the chimney. By an arrangement of dampers said waste heat or gases, is
introduced into the flues of a steam boiler or boilers for the purpose of generating
the steam to be supplied to the evaporator.
But in order that our said invention and the manner of performing same may be
properly understood we have hereunto appended an explanatory sheet of drawings
in which
Fig. 1 is a sectional elevation of a multitubular boiler, and flues taken upon
the line y of Fig. 2.
Fig. 2 is a sectional plan of same taken upon the line A B Fig. 1.
Referring to the said drawings A is the multitubular boiler which is connected
to the evaporator B by the steam pipe C. D is the flue leading from the still
flues to the chimney, which is fitted with dampers E, F so arranged that the
damper E can be closed and the damper F opened to allow the waste heat or gases
to be led directly to the chimney; or the damper F closed and the damper E
opened when it is desired to lead the heat into the side flues G of the boiler A as
shewn. In the latter case the heat or gases descend by the flues H, into and along
the furnace flues L, as shewn more particularly in Fig. 1, returning through the
tubes of the boiler and escaping into the chimney flue from M. N represents
a dumb plate which separates the tubes from the furnace flue. A usual front,
combining smoke box and furnace doors, encloses the whole so that when the heat
requires to be augmented the boiler can be fired in the usual way.
The liquid to be evaporated is pumped or forced into the evaporator B through
the pipe O and the residue blown out through the pipe P at such density as may
be considered suitable for future use in applying it to cattle feeding or other
purposes.
The steam generated from the evaporation of the refuse liquid may escape from
the evaporator through the valve Q and be applied to any required purposes,
whilst any water of condensation in the coils may be run off by the cock R and
led by a pipe to a hot well for feeding the boiler.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what we
claim is:
1. The evaporating of distillery-bye-products by means of steam, in the manner
as hereinbefore described.
2. The utilizing of waste heat from the still flues for generating steam for this
purpose, substantially as herein before described and shewn in the accompanying
drawings or any mere modification of the arrangement described and shewn."
