An Apparatus for Drying and Conditioning Grain and other similar
material.
I, JAMES WALWORTH, of Longfield Villa, Legrams Lane, Bradford in the
County of York, Corn Mill 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 :-
This invention consists of a stationary dryer wherein steam pipes are used to
produce the hot air necessary for drying or conditioning purposes.
To carry out my invention, I employ a series of steam pipes formed with two, or
more longitudinal flanges, in order to produce a greater radiating surface.
I arrange those pipes by preferenco vertically in rows placed alternately, one
being connected with the other at the top, and bottom, and having a suitable inlet
valve for steam, and outlet valve for steam & water.
I enclose these pipes in a rectangular casing formed of sheet metal, & the back
and front side perforated sheet metal or wire gauze, at a suitable distance from and
parallel with one of these perforated sides, I place another plate of perforated sheet.
metal or wire gauze, to the outer edges of which I attach a conical sheet metal
casing, terminating with a suction fan or air propeller. The vertical space at each
end between the two perforated walls is made up with two plain sheets of metal.
The material to be dried or conditioned is fed into a suitable hopper fixed over-
the opening at the top of the two perforated walls being dried in its descent to the
bottom, by means of the suction fan or air propeller hereinbefore mentioned drawing
the hot air produced by the steam pipes, through the two perforated walls, and thus
through the grain passing between them.
By this method the grain receives the same treatment throughout in its transit.
to the delivery.
In order that my invention may be fully understood I will proceed to describe-
the same with reference to the accompanying drawings in which
Figure 1 represents a side elevation partly in section of my improved drying and.
conditioning apparatus.
Figure 2 represents of a plan having the top cover removed, of my improved
drying and conditioning apparatus.
Figure 3 represents a sectional plan of the pipes for producing the hot air, and
Figure 4 ropresents a front elevation of the hot air chamber partly in section.
Similar letters refer to similar parts in each figure.
The grain etc. to be dried or conditioned is fed into the hopper A and from thence
passes down between the perforated walls B and C, where it is dried by means of
the hot air produced by the steam pipes D. The hot air being drawn through the
perforated walls B and C by the suction fan or air propeller E fixed at the extent
of the conical chamber F. The steam pipes D are formed with longitudinal.
flanges H, in order to produce a greater radiating surface, and at the same time
partially obstructing the inlet of air.
The steam pipes may be arranged either vertically or horizontally within the-
casing J, which has the internal wall B and the external wall K formed of perforated
sheet metal or wire gauze.
The grain after being dried is cooled in its decent below the level of the hot air
chamber J by means of a current of cold air drawn through the two perforated
walls B and C respectively which are elongated for this purpose. The grain is.
discharged by means of the delivery roller M, the outlet O being regulated by the:
sliding door N which may be raised or lowered as required.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what mannor the same is to be performed declare that what
I ulaim is;
:
1st. In an apparatus, for drying or conditioning grain etc. the hot air chamber J
enclosing the steam pipes D in combination with the three perforated walls B, C,
atid K substantially in the mannor, and for the purpose herein described and
represented in the accompanying drawings.
2nd. In an apparatus for drying, or conditioning grain etc. The two perforated
walls B, & C, between which the grain passes in its decent to the delivery in com-
bination with the suction fan, or air propeller H and conical chamber F, substantially
in the manner, and for the purpose herein described, and represented in the accom-
panying drawings.
