PATRICK RICHARD NORTON, of 33, Rutland Square, Dublin, in the County of
Dublin, Ireland "IMPROVEMENTS IN KILNS FOR DRYING MALT, WHEAT, BARLEY,
AND OATS"
This Invention relates to improvements in kilns for drying malt, barley, wheat,
or oats, whereby the producing capacity of the kiln will be doubled, and the
process of drying carried on in a continuous manner, the dried article being greatly
improved in quality.
For this purpose I propose to construct a kiln consisting of two floors-one
placed above the other, and formed of iron perforated plates, wire netting, or
perforated tiles (I prefer the latter). The two chambers formed by these two floors
communicate with each other, and also with the hot air chamber underneath the
lower floor by means of suitably arranged flues or pipes provided with suitable
valves for regulating the flow of hot air to the said chainbers. By these flues, or
pipes, a perfect system of current and ventilation can be secured for both floors of
the kiln; and all moisture can be eliminated from the air, thereby greatly
accelerating the process of drying.
By the arrangement of these two floors the material placed on the upper one,
which I call for convenience No. 1, is dried slowly during a certain period of the
process of drying, when the material is dropped by suitable means on to the
second floor which I call No. 2, where it comes more directly in contact with the
hot air chamber underneath, and can then readily be thoroughly home-dried to any
extent required.
Malt or other grain treated in this manner is free from the injurious effects to
which it is subject when placed, in the first instance, in close contact with the
furnaces.
Further, two floors of corn are in operation (or process of drying) at the same
time; so that the arrangement herein proposed may be considered a continuous
system of carrying on the said process of drying malt or other grain, and at a
considerably greater saving than by methods hitherto used.

PATRICK RICHARD NORTON, of 33 Rutland Square, Dublin, in the county of
Dublin, Ireland, IMPROVEMENTS IN KILNS FOR DRYING MALT, WHEAT, BARLEY,
AND OATS"
This Invention relates to improvements in kilns for drying malt, barley, wheat,
or oats, whereby the producing capacity of the kiln will be doubled, and the
process of drying carried on in a continuous manner; the dried article being also
greatly improved in quality.
For this purpose I propose to construct a kiln consisting of two floors-one
placed above the other-formed of perforated plates, wire netting, or perforated
tiles (I prefer the latter). The two chambers formed by these two floors communi-
cate with the hot-air chamber underneath the lower floor by means of suitably-
arranged flues, or pipes, provided with suitable valves for regulating the flow of
hot air to the said chambers. By these flues, or pipes, a perfect system of current
and ventilation can be secured, and all moisture eliminated from the grain, thereby
greatly accelerating the process of drying.
By the arrangement of these two floors the material placed on the upper one is
dried slowly during a certain period of the process of drying when the material
is dropped by suitable means on to the second floor where it comes more directly in
contact with the hot-air chamber underneath and can then be thoroughly home
dried to any extent required.
Malt or other grain treated in this manner is free from the injurious effects to
which it is subject when placed in the first instance in close contact with the
furnace. Moreover, two floors of corn are in operation or process of drying at the
same time, so that the arrangement herein proposed may be considered a continuous
system of carrying on the said process of drying malt or other grain.
The accompanying drawing represents a longitudinal section of a kiln con-
structed according to my invention. Over the furnaces A, A, is the hot-air
chamber B from which hot air is conveyed to the first floor by four flues, two of
which are shown at C, C. These flues are placed at suitable distances apart and
discharge themselves just above the malt or grain undergoing the process of
drying. D, D, are the flues or passages which communicate between the hot-air
chamber and the upper floor. These flues I prefer to arrange at each corner of
the kiln. They discharge themselves immediately over the malt or grain placed on
the floor as in the case of the flues conveying heat to the first described floor. All
these flues or passages are provided with dampers or suitable valves a, a, for the
purpose of controlling the passage of hot air through them, so that when required
all the hot air can be condensed into the hot-air chamber when completing the
drying, or allowed to spread between the kilns so as to dry the malt slowly and
evenly in the first instance. Any number of flues or passages may be used
according to size of kiln. The upper kiln is constructed on a wooden frame
supported on flitch beams and resting on metal pillars, which latter are a con-
tinuation of the pillars supporting the lower kiln the frame of which is constructed
of iron in the usual way. The upper floor is thus constructed to obviate the evils
resulting where a considerable surface of iron is exposed to vapor-much rust
occurring, which falling on the malt underneath would injure it. Trap-doors may
be arranged in the upper kiln for the purpose of letting down malt or grain to
lower kiln in a convenient manner to complete drying.

page_text: When this invention is used in connexion with malt-houses the capacity of the
malt-house is likewise increased to double its ordinary capacity for the manufacture
of malt.
Having thus described the nature of my said Invention and the manner of
carrying the same into practice, I would have it understood that what I consider
new and useful, and therefore claim as the invention to be secured to me by the
herein before in part recited Letters Patent is.-
The construction and application of kilns for drying malt and other grain,
substantially in the manner herein described and set forth.
In Witness whereof I, the said Patrick Richard Norton, have hereunto set my
hand and seal this Seventeenth day of July, in the year of Our Lord, One
thousand, eight hundred and eighty three.
