Improvements in Apparatus for Drying Barley, Malt, Oats, Wheat,
or other Substances of a Granular or Pulverulent Nature.
I, JAMES WHITE of 37 Mark Lane in the City of London, Miller and
Merchant, do hereby declare the nature of this invention to be as follows:-
My invention has reference to apparatus for drying barley, malt, oats, wheat or
other substances of a granular or pulverulent nature, and a characteristic feature
of the invention is an inclined or vertical channel formed with open work or per-
forated sides, and divided transversely at suitable intervals into chambers the
bottoms of which are composed of cross passages; these passages are so arranged
that when the 'barley or other material under treatment is allowed to run or
flow from one chamber to that next below, the passages transfer the material that
was at and near the respective sides of the upper chamber to the opposite sides of
the lower chamber, whereby the material gets well mixed and turned over and is
consequently more uniformly, dried than if it were merely allowed to slide bodily
from chamber to chamber. The chambers have preferably a central tongue or
board projecting up from the top of each series of cross passages, and a similar
tongue, or board projecting down from each series, these tongues serving as guides
or dividers for the material in entering and leaving the passages. The lowest
chamber is not fitted with cross passages, but has a slide or shutter at top. and
another slide or shutter at bottom, the bottom slide being normally kept closed,
and these slides are worked at intervals to allow the material in the several
chambers to move down one stage, that is, to the extent of one chamber. To effect
this the upper slide is closed and the bottom slide is then opened to allow the
lowest chamber to empty itself into a shoot or receptacle. The bottom slide is
then closed and the top slide opened when every chamber (except the lowest) will
empty itself through the cross passages into the chamber next below and become
filled from the chamber next above, the top chamber receiving its supply from a
hopper or otherwise.
In carrying out the invention it will be convenient to employ two inclined
channels divided transversely as above described, the two channels meeting at the
top so as to form a sort of A, and they may both be supplied by the same hopper.
Further it will be well to have a number of inclined channels, say 5 more or less,
placed abreast, each of them meeting at the upper end another inclined channel so
as to form a A.
The channels are arranged in any suitable kiln or drying house heated either by
a stove or fire therein or by an external air heating stove connected therewith, or
otherwise.

Improvements in Apparatus for Drying Barley, Malt, Oats, Wheat,
or other Substances of a Granular or Pulverulent Nature.
I, JAMES WHITE of 37 Mark Lane in the City of London, Miller and Merchant,
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 :--
:
or
My invention has reference to apparatus for drying barley, malt, oats, wheat
other substances of a granular or pulverulent nature, and a characteristic feature
of the invention is an inclined or vertical channel formed with openwork or per-
forated sides and divided transversely at suitable intervals into chambers the
bottoms of which are composed of cross passages; these passages are so arranged
that when the barley or other material under treatment is allowed to run or flow
from one chamber to that next below, the passages transfer the material that was
at and near the respective sides of the upper chamber to the opposite sides of the
lower chamber, whereby the material gets well mixed and turned over and is con-
sequently more uniformly dried than if it were merely allowed to slide bodily from
chamber to chamber. The chambers' have preferably a central tongue or board
projecting up from the top of each series of cross passages and a similar tongue or
board projecting down from each series, these tongues serving as guides or dividers
for the material in entering and leaving the passages. The lowest chamber is not
fitted with cross passages but has a slide or shutter at top and another slide or
shutter at bottom, the bottom slide being normally kept closed, and these slides are
worked at intervals to allow the material in the several chambers to move down
one stage, that is, to the extent of one chamber. To effect this the upper slide is
closed and the bottom slide is then opened to allow the lowest chamber to empty
itself into a shoot or receptacle. The bottom slide is then closed and the top slide
opened when every chamber (except the lowest) will empty itself through the
cross passages into the chamber next below and become filled from the chamber
next above, the top chamber receiving its supply from a hopper or otherwise.
In carrying out the invention it will be convenient to employ two inclined
channels divided transversely as above described, the two channels meeting at the
top so as to form a sort of A. and they may both be supplied by the same hopper.
Further it will be well to have a number of inclined channels, say five more or less,
placed abreast, each of them meeting at the upper end another inclined channel so
as to form a A
i
The channels are arranged in any suitable kiln or drying house heated either by
a stove or fire therein or by an external air heating stove connected therewith, or
otherwise.
In the accompanying drawings
Figure 1 is a vertical section on the line 1-1 of Figure 2 of a kiln or drying
house fitted with my improved-apparatus, the side of one of the inclined channels
being broken away so as to allow the bottoms of the chambers to be seen.
Figure 2 is a vertical section of the kiln on the line 2-2 of Figure 1.
Figure 3 is a side elevation on a larger scale. of the bottom of one of the
chambers, together with the upper and lower dividing tongues.
Figure 4 is a section on the line 4-4 of Figure 3 and
Figure 5 is a section on the line 5-5 of Figure 3.
In these drawings a represents the kiln or drying house and b a stove or fire
place for heating the same. cc are air outlet passages leading from the interior of
the kiln to the final outlet d at top. e e represent two sets of inclined channels of
which there are five in each set, but I do not limit myself to this number. The
five channels of the one set are shown as respectively meeting the five channels of
the other set, but this is not essential. f is a hopper from which the ten channels

page_text: receive their supply of barley, oats or other material to be dried. The hopper and
the upper ends, of the channels are supported by the floor g, and the lower ends of
the channels are supported by the floors or platforms hh. Each channel e is
divided transversely into chambers or compartments; five chambers are shown in
each channel but I do not limit myself to this number. The bottom of each
chamber except the lowest is formed by a transverse partition in which are two
sets of passages k and 1; these two sets cross each other as clearly seen in
Figures 3, 4 and 5. Between the tops of the passages and those of the passages lis
a central tongue or board m projecting up from and extending the whole length of
the partition ; and between the bottoms of the passages k and those of the
passages is a similar central tongue or board m³ projecting down from said
partition. At the top of the lowest chamber of each channel e is a slide or
shutter n which is normally open and at the bottom of the said chamber is a slide
or shutter p which is.normally closed. The slides n p can be opened and closed as
into
required by men on the platforms hh. Below, the lowest chamber is a shoot
which the material in the said chamber falls when the bottom slide is opened and
which delivers it outside the kiln. The lowest chambers of all the channels e of oue
set communicate with one common shoot q, but a separate shoot may be provided for
each channel when required. In the arrangement shown there is a separate shoot
for each set of five channels.
q
The operation of the apparatus will be readily understood:-All the chambers or
compartments of all the channels being filled with the material to be dried the
bottom shutters p being closed and the top shutters n open and the kiln being
heated, the drying proceeds. When it is desired to cause the material in any given
channel to descend to the distance or extent of one chamber the upper slide n of
that channel is first closed and the lower slide p opened, so that the contents of the
lowest chamber discharge themselves into the shoot ; the slide p is then closed
and next the slide n is opened, and the contents of every chamber of the channel
then discharge themselves into the chamber next below, the top chamber being
automatically re-filled from the hopper f. As the material passes from one
chamber to another the cross-passages k and I cause it to change sides in the channel,
this change being assisted by the upper and lower tongues or dividers m and m³.
Instead of the kiln or drying house being heated by an internal stove or fire
place as shown in the figures it may be heated in any other convenient manner such
for example as by hot air from an external air heating stove connected with the
kiln or drying house by a flue or flues.
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 is-:-
1. In a kiln or drying house in which barley, malt, oats or other substances of a
granular or pulverulent nature are dried in their passage down an inclined or
vertical channel, transverse partitions in the said channel dividing the same into
chambers or compartments and having cross passages to transfer the substance from
one side to another of the said channel as the said substance passes from one
chamber to another, substantially as and for the purpose set forth.
.
2. In a kiln or drying house in which barley, malt, oats or other substances of a
granular or pulverulent nature are dried in their passage down an inclined or vertical
channel, the combination with transverse partitions in the said channel dividing the
same into chambers or compartments and having cross passages to transfer the
substance from one side to another of the said channel as the said substance passes
from one chamber to another, of an upper and a lower projecting tongue on each
partition to guide or divide the said substance as it enters and leaves the said cross
passages, substantially as set forth.
3. In a kiln or drying house for drying barley, malt, oats or other substances of
a granular or pulverulent nature, a channel down which the substance to be dried
passes, having transverse partitions with cross-passages, the said partitions dividing

page_text: the said channel into chambers or compartments and the lowest chamber having a
movable shutter at top and a movable shutter at bottom, in combination with a
hopper to feed the upper end of the said channel and a shoot to receive-the
dried substance discharged from the lower end of the said channel, substantially as
set forth.
4. The improved apparatus constructed and working substantially as herein before
described and represented in the accompanying drawings for drying barley, malt,
oats, wheat or other substances of a granular or pulverulent nature.
