PROVISIONAL SPECIFICATION.
Improved Arrangement of Apparatus or Kiln for Drying Grain.
I, THOMAS STRACHAN, of 28 Cadogan Terrace, Victoria Park, Middlesex,
Distillers Engineer do hereby declare the nature of this invention to be as
follows:-
The object of this invention, is to arrange a kiln or grain dryer with two vertical
open meshed cylinders, between which spiral blades are fixed and down which the
grain to be dried is permitted to slide gradually, as withdrawn from valved openings
by one or more creepers arranged horizontally to move the dried grain to any receiver,
which may be in connection with elevation mechanism to enable the grain to be diverted
through suitable shoots or spouts to any given spot.
The grain is fed to the drying cylinder through a funnel mouth, from which it slides
on to an internal cone for distribution to the spiral blades.
The central part of the inner meshed cylinder is provided with a hot air tube
supplied by a fan or blower and the air issuing from the tube percolates between the
meshes of the inner cylinder then through the moving wall of grain and then through
the meshes of the outer cylinder.
The sliding action of the grain in its descent in a spiral direction becomes con-
stantly turned over and round by contact with the neighbouring grain and both feed
and the withdrawal can be adjusted to suit the length of time that the grain has to be
exposed to the action of the through-flowing hot air from the inside to the outside of
the kiln.
I purpose arranging other elevations if desired to raise the grain for a re-heating or
drying during a second travel in the kiln, if such be needed.

I, THOMAS STRACHAN, of 28 Cadogan Terrace, Victoria Park, Middlesex, Distillers
Engineer, 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 this invention is to arrange a kiln or grain dryer in a novel
manner.
The invention is shown in the annexed drawings, Figure 1 being a part sectional
elevation and Figure 2 a partial plan. A, B, are two vertical open meshed cylinders
between which, blades C, C, are fixed, and down which the grain to be dried is
permitted to slide after being fed from the hopper D supplied by the endless chain of
buckets or elevating cups E, E. The grain falls gradually as withdrawn from valved
hoppers or openings at F, F, by one or more creepers G arranged horizontally to
move the dried grain to any receiver, such as that shown at H which is in connection
with elevator mechanism I, I, to enable the grain to be diverted through suitable shoots
or spouts J, J, to any given spot.
The grain as fed to the drying cylinders A, B, first slides on to an internal cone K
for distribution to the spiral blades C, C. The central part of the inner meshed
cylinder A is provided with a hot air tube L supplied by a fan or blower M and the
air issuing from the tube L percolates between the meshes of the inner cylinder A
then through the moving wall of grain and then through the meshes of the outer
cylinder B.
The sliding action of the grain in its descent in a spiral direction.becomes con-
stantly turned over and round by contact with the neighbouring grain and the.feed
and the withdrawal can be adjusted to suit the length of time that the grain has to he
exposed to the action of the through-flowing hot air from the inside to the outside of
the kiln.
I purpose arranging other elevators if desired to raise the grain for re-heating or
drying during a second travel in the kiln, if such be needed.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is
1. In an apparatus for the drying of grain, the combination of two fixed meshed
cylinders A, B, with fixed spiral or helical partitions C, C, between such two
cylinders A, B, as and for the purpose described.
2. The general construction or arrangement of apparatus shown on the drawings,
to enable grain to be dried by air forced through a freely moving wall, of grain
temporarily held between two meshed cylinders, into and from which the air has play,
as described.
