EDWIN WILSON High Street Tadcaster Yorks, Brewer, do hereby declare the
nature of this invention to be as follows
-
In the application of the direct products of combustion in the drying curing
and torrifing of malt in combination with the system of exhaust or atmospheric
attenuation patented in 1886 by Henry Wilson of Stockton on Tees No 11208
instead of using steam pipes to heat the air as shewn in that specification, a close
furnace is used through which the air is drawn by the action of the exhaust engine
in the same manner as described-The improvements claimed being that Malt &
Hops are more perfectly cured cooked & purified by the gases arrising from
direct fire heat applied to the air than when the air is heated by radiation alone-
The same application of fire heated air is used for the purification & drying of
casks and other like vessels the air may either be driven into them under pressure
or drawn into them under vacuo

I, EDWIN WILSON, High Street, Tadcaster, West Yorkshire, Brewer, 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 my invention relates to certain new and useful improvements in drying and
curing malt and hops, and in purifying and drying casks and the like, and which
invention consists in providing means whereby the malt etc is dried and cured by
means of hot air being drawn through a suitable case (hereinafter referred to as
the malt case) in which the malt ete is placed for drying and curing
It further consists in the provision of means for the drying and curing of malt etc
in vacuum as will be hereinafter described Said invention also provides for the
utilisation of the heated air for the purposes of purifying casks and other vessels,
and furthermore for supplying air for the termenting room
I now proceed to describe my said invention, reference being had to the accom-
panying drawings and the figures and letters of reference marked thereon, similar
letters indicating like parts throughout
Fig 1 is a general view of my invention, and Fig 2 is a top plan view of the
malt case
The malt case is preferably situated upon the topmost floor of the building, and it
consists for the most part of a square or other shaped box A, preferably constructed
of wood and lined with tin, zino or other suitable metal or material a, but which
case may however be made of metal etc In the lower part of the malt case is a
perforated bottom R which is inclined towards the centre as shown, and rests upon
two opposite and perforated cylinders b In the upper part or top of the malt case
is a perforated piece of metal C, which strains the air of small pieces of malt etc.
and a suitable door D which enables access to be had to the interior of the case,
and is capable of being made air tight when fastened down
In order to draw the heated air through the malt case A, I provide any suitable
steam or other exhaust pump E, which is preferably situated in the engine house, and
which is in direct communication with the upper part or top of the malt case through
pipe F
the
The heat is supplied by a closed furnace G, the flue g of which is connected to a
pipe H which is connected to the pipe F at f, and bas a branch pipe J connected at
or about at to the pipe F, said pipe H terminating in an outlet K which opens out
to the atmosphere The pipe His connected to the malt case A by means of the
pipes Land M, the pipe L being fitted with a circular or other ventilator 1, and the
pipe M connected to the perforated cylinders b as shown
The pipes F, H, J and L are provided at convenient positions with suitable shdes
or valves, N, O, P, Q, R, S, and T by means of which the flow of air through the
pipes may be diverted or cut off, as will be hereafter pointed out

page_text: The pipe e is connected to a suitable furnace used for drying and purifying casks,
and also serves to supply air to the fermenting room
-
The manner in which my improved drying apparatus is operated is as follows
The malt hops or other articles to be dried or cured are placed in the box or
case A, and the door D having been fastened down, the hot air may be drawn
through the case from the top or from the bottom thereof as desired, and in the
directions indicated by the arrow heads, the arrow heads drawn in full lines showing
the course taken by the air when drawn from the top, and the arrow heads drawn
in dotted or broken lines showing the direction taken by the air when it is drawn
from the bottom of the case When it is desired to draw the air over the top of
the case (as indicated by the arrow heads in full lines,) the slides or valves N, P, R
and S are opened, the others being closed, and when it is desired to draw the air
from the bottom of the case, the slides P, R are closed and the slides Q, O are
opened
The slide T is only opened when starting a fire in the furnace
It is found well to create a vacuum in the case occasionally before commencing
to heat the air, and also at the finish of heating, which vacuum is created by
closing all the slides or valves
The temperature may be regulated by the circular or other ventilator / which is
capable of admitting air at all times
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim 18-
The combination, of the case A, constructed as described, of the connecting
pipes F, H, J, L and M, said connecting pipes having suitable slides or valves, and
communicating with the furnace, engine and malt case, and of the engine and
furnace, whereby heated air is supplied to the malt case, all substantially as and for
the purposes herein before set forth and illustrated in the drawings hereunto
annexed
Dated this 4th day of March 1889
