Improvements in Grain Drying and Conditioning Apparatus.
WILLIAM HOLLAND, of Mill House, Wordsley, in the County of Stafford,
Miller. do hereby declare the nature of this invention to be as follows:-
--
This invention relates to unprovements in the combination of apparatus for
drying and conditioning grain of various kinds, and more particularly intended for
that of wheat
It consists as follows I provide a trough or casing, which may be varied in
sectional area such as round, half round, or otherwise. Its length too may be
varied according to requirement. Running the length of this trough, is a rotative
conveying screw, the speed of which may be regulated to the requirements of the
wheat, this screw is carried upon a suitable spindle and in suitable bearings. At
the one end of the trough is an inlet through which the grain which is to be dried
is fed, and at the other end a suitable outlet is made for the dried grain to escape
I now further provide a hot air inlet at or near the outlet cod of the trough This
hot air may be forced into the said trough by any suitable means, but in such a
manner that it shall thoroughly mix with and permeate the giam as it is boing
conveyed along by the worm. If desired may provide two or more inlets for the
hot an, along the said though, or in some cases if desired, the spindle on which is
carted the crew may be made hollow and used for conveying the heated air to
the giau. In order to prevent the inflowing heated an escaping with the grain at
the outlet, I may attange suitable valves, baftlers or the like at the outlet of the
gian, also a similar valve &c. may be placed at the giam inlet to prevent the hot
air too hastily rushing through &c. Along the top of the trough, or other convenient
place or places, vapour outlet valves or openings are arranged which may be opened
or closed at will or pressure to permit of the vapour created from off the grain to
езспре.
In some cases, instead of making the trough or casing fixed, I may make it to
evolve also, with a different speed to that of the worm This arrangement may
be beneficially adopted when there is liability to clogging of the grain at the
lower side of the trough. In this case, as will be readily seen, the transverse
sectional shape of the tiough would require some modification to sint
In order to condition or cool the dried wheat &c., I use a similar apparatus to
that aliendy described for drying the wheat From the outlet of the drying
apparatus provide suitable arrangements for carrying the dried wheat to the
Inlet end of the cooling apparatus, and at or near the outlet and of the said cooling
or conditioning apparatus I provido means whereby a blast of cold an, shall enter
and diffuse itself through the gram as it incets it, and thereby cools it and
"conditions it (as it is termed) that 18, it brings it to its required condition and at
once makes it fit for milling.

I WILLIAM HOLLAND, of Mill House, Wordsley, in the County of Stafford,
Miller, 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 relates to improvements in the combination of apparatus for
drying and conditioning grain of various kinds, and more particularly intended for
that of wheat.
In order to more particularly explain this my invention, I have appended
hereunto illustrative sheets of drawings, upon which are figures and numbers of
reference, similar numbers referring throughout the several views to the same
thing or part.
Fig. 1, 18 a general sectional view of this my invention.
Fig. 2, 18 a sectional view showing a modification in which the trough is made to
revolve in addition to the worm.
Fig. 3, is a frout view of the "paddle" worm.
Fig. 4, is a section of the worm on line A-B (Fig. 3).
Fig. 5, is a section of the worm on line C-D (Fig. 3).
It consists as follows:-I provide a trough or casing 6, which may be varied in
transverse sectional area such as round, half round, or otherwise. Its length too
may be varied according to requirements. Running the length of this trough is a
rotative conveying screw, whose shape may be varied, but preferably consists of
what are known as "paddles," as seen at 7,7, arranged screwwise the speed of
which may be regulated to the requirements of the wheat.
This screw is carried upon the spindle 8, and in suitable bearings 9, 9, upon the
standards on other supports 10. At the other end of the trough is an inlet 11,
through which the grain which is to he dried is fed, and at the other end a suitable
outlet 12, is made for the dried grain to escape, and to pass into the lower trough,
finally escaping at 12°, as shown by double arrows. I now further provide the hot
an inlet at 13, or near the outlet end of the trough This hot air may be forced
into the said trough by any suitable means, and in the direction indicated by the
single arrows, but in such a manner that it shall thoroughly mix with and permeate
the grain as it is being conveyed along by the worm. If desired I may provide
two or more inlets for the hot air, along the said trough, or in some cases if desired,
the spindle on which is carried the screw may be made hollow and used for
conveying the heated air to the giai. In order to prevent the inflowing heated
air escaping with the grain at the outlet, I may arrange suitable valves, bafflers or
the like at the outlet of the grain, such for instance as shown at 14, in which the
valve 14, 1s pivoted at 15, and counterbalanced by weight 16, also a similar
valve &c. may be placed at the grain inlet 11, if required, generally however it is
not so required, to prevent the hot air too hastily rushing through &c. Along the
top of the trough, or other convenient place or places, vapour outlet valves or
openings 17, are arranged which may be opened or closed at will, by means of the
slide 17, or other suitable contrivance, to permit of the vapour created from off the
grain to escape. Motion is imparted to the spindles &c. by means of the pulley 18,
and toothed wheels 19, 19, or other suitable driving gear.
In some cases, instead of making the trough or casing fixed, I may make it to
revolve also, as seen in Fig. 2.
Any suitable mechanical means or arrangement may be adopted to effect the
rotation of the trough, but ono way of carrying it out as illustrated is as follows*.
The spindle 8º, bearings 95, standards 10, inlet 11ª, outlet 12ª, and air inlets &c.,

page_text: are arranged substantially as before described The ends of the trough at 20,
and 21, are separated from the central part 6, of the trough which latter is free to
revolve in the fixed bearings 22, 22. The jointing of the trough at 23, 23, up to
aud against the stationary ends 20, 21, is so made as to best prevent the escape of
grain and also leakage of hot air. Upon the trough is secured the toothed
wheel 24, which gears with toothed pinion 25, carried upon the shaft 26, which
latter may derive its motion from any available source. Any other convenient
driving mechanism may be adopted as for instance, instead of the wheel 24, I may
use a band or chain pulley and drive direct or otherwise
Such an arrangement may be beneficially adopted when there is liability to
clogging of the grain at the lower side of the trough. In this case, as will be
readily seen, the transverse sectional shape of the trough would be of a circular
shape.
In order to condition or cool the dried wheat &c. I use a similar apparatus to
that already described for diying the wheat, as shown in the lower part of Fig. 1.
From the outlet 12, of the drying apparatus, I carry the dried wheat to the inlet
end of the cooling trough 6b, and at or near the outlet end 12°, of the said cooling or
conditioning tough 6, I provide any ordinary suitable means whereby a blast of
cold air, shall enter at 13, and diffuse itself through the grain as it meets it, and
thereby cools it and "conditions" it (as it is termed) that 18, it brings it to its
1 equned condition by the time it reaches the final outlet 12, and at once makes it
fit for milling.
It will be seen that by this arrangement that the apparatus also simultaneously
effects the conveyance of the grain, from one place to another. The number and
direction of troughs &c. may be increased if desired.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I clain is-
1. In apparatus for “drying” grain the combination with the trough, stationary
or rotary, with its supply inlet and discharge outlet, and rotating screw or conveyer,
of a hot air inlet such as 13, by which the hot air is diffused through the grain in
the opposite direction to which the latter is travelling, substantially as described
and shown.
"
2. In apparatus for "conditioning or cooling grain, the combination with the
trough, stationary or rotary, with its supply inlet and discharge outlet, and rotating
screw conveyer, of a cold air inlet such as at 13, by which the cold air is permeated
with and passed through the gram as it meets the latter, substantially as set forth
and shown.
3. The combination with the "drying" apparatus as herein sot forth and shown,
of the conditioning or cooling apparatus as herein set forth and shown.
4. The general combination and arrangement of mechanism constituting this my
improved arrangement for drying and conditioning, severally or combined, as set
forth and shown.
Dated this 19th day of April 1895.
