AN IMPROVEMENT. IN APPARATUS FOR DRYING OR DESICCATING SUBSTANCES BY MEANS OF HEATED AIR
Year: 1884

page_text: I, CHARLES DENTON ABEL of N° 28 Southampton Buildings, Chancery Lane, in
the County of Middlesex, Consulting Engineer and Patent Agent do hereby
declare the nature of my invention for AN IMPROVEMENT. IN APPARATUS FOR
DRYING OR DESICCATING SUBSTANCES BY MEANS OF HEATED AIR, to be as follows:
This invention relates to apparatus for drying or desiccating substances described
in the Specification to Patent N° 4556 of 6th November 1880; in this apparatus
the cooling of the dried material was effected by causing the air required for
drying to be drawn, while still cold, through one part of the apparatus, in such
manner that the dried material, in travelling towards the outlet of the apparatus
had to pass through the cold air travelling in the contrary direction.
According to the present improvement there are provided in the side walls A of
the exit part of the apparatus horizontal passages in which are placed pipes that
communicate with the interior of the apparatus by lateral openings or nozzles.
Into these pipes cold air is forced by a fan or other blowing machine, so as to issue
through the openings into the interior of the apparatus and thus effect the cooling
of the material before its exit from the apparatus.
In the arrangement preferred, the two pipes in the two side walls are connected
to one and the same transverse pipe at the one end having a branch leading to a
blowing machine that supplies both pipes with air.
The air for drying is in this arrangement consequently not drawn in through part
of the apparatus, as described in the arrangement of Patent N° 4556%, but is
forced in directly from the outside by the blowing machine, and after traversing.
the material to be cooled it is blown in a warmed condition through those parts
of the apparatus in which the materials to be dried are situated. If no artificial
cooling of the dried materials is required, it is only necessary to put the described
arrangement out of action.

I, CHARLES DENTON ABEL of N° 28 Southampton Buildings Chancery Lane in
the County of Middlesex, Consulting Engineer and Patent Agent do hereby
declare the nature of the said invention for "AN IMPROVEMENT IN APPARATUS
" and in
FOR DRYING OR DESICCATING SUBSTANCES BY MEANS OF HEATED AIR
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, that is to say:-
This invention relates to apparatus for drying or desiccating substances described
in the Specification to Patent N° 4556 of 6th November 1880; in this apparatus
the cooling of the dried material was effected by causing the air required for
drying to be drawn, while still cold, through one part of the apparatus, in such
manner that the dried material, in travelling towards the outlet of the apparatus
had to pass through the cold air travelling in the contrary direction towards a
blowing machine which then propelled it through the heating apparatus, and
through the passages containing the material requiring to be dried.
The present invention relates to a different mode of effecting such cooling
operation which will be understood on reference to the accompanying drawing in
which Fig. 1 shews a longitudinal section, Fig. 2 a sectional plan, and Fig. 3 a cross
section of the apparatus, with that part of the mechanism which does not relate to
the present'improvements omitted.
According to the present improvement there are provided in the side walls 'A of
the exit part of the apparatus horizontal passages in which are placed pipes R that
communicate with the interior of the apparatus by lateral openings or nozzles O.
Into these pipes cold air is forced by a fan or other blowing machine, so as to issue
through the openings into the interior of the apparatus and thus effect the
cooling of the material before its exit from the apparatus.
In the arrangement preferred, the two pipes R in the two side walls are connected
to one and the same transverse pipe at the one end having a branch leading to a
blowing machine that supplies both pipes with air.
The air for drying is in this arrangement consequently not drawn in through
part of the apparatus, as described in the arrangement of Patent N° 4556 of 1880
but is forced in directly from the outside by the blowing machine, and after
traversing the material to be cooled and the heating apparatus at X, it is blown in
a warm condition through those parts of the apparatus in which the materials to
be dried are situated. If no artificial cooling of the dried materials is required, it
is only necessary to put the described arrangement out of action.
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
In apparatus for drying or desiccating substances such as is herein referred to,
effecting the cooling of such substances before they issue from the apparatus by
means of cold air blown into the exit parts of the apparatus through special pipes
arranged in the walls of such parts, substantially as herein described.
