Improvements in Kilning Malt, and in Structures and Apparatus
therefor.
I, RICHARD HOWARD LEAKER, of Montague Villa, Kingsdown Parade, in the
City and County of Bristol, Engineer, do hereby declare the nature of this inven-
tion to be as follows:-
:-
This invention relates to kilning malt and consists in an improved system of
effecting the same, and in buildings, and apparatus therefor.
According to this invention, two kilning floors are employed, one placed over the
other. The furnace is below the lower kilning floor and when the said lower floor
only is being used for kilning, the heat is directed to pass through the "slopes," or
conical or tapered chamber, above the furnace to the underside of the floor, as is
usual; the widest part of the said chamber being immediately below the floor. The
heat passing through the perforations in the floor permeates the grain in the usual
way and the fumes discharged escape by a chimney into which they are directed
by a conical hood fixed over the floor.
When the upper floor only is being used for kilning, a damper situated in a pipe
extending from the furnace to the chimney is opened and the heat instead of passing
up through the chamber above the furnace ascends in the said pipe whence it is
directed by a second damper into branch pipes which conduct it to the underside of
the upper floor. After passing through the perforations in the upper floor and
through the malt thereou, the fumes escape through ventilators in the roof.
When kilning is required to take place on both floors, the heat is directed by the
dampers in such manner that the supply thereof to each floor is independent to that
of the other, the fumes from the lower floor being prevented from passing through
the upper floor.
The central tube aforesaid communicates at the lower end with a pipe or duct
from which cold, dry, filtered air is supplied to cool the malt after it has been
kilned, or for the purpose of withering the green corn on the floors. Such supply
of air is controlled by suitable dampers.

Improvements in Kilning Malt, and in Structures and Apparatus
therefor.
1, RICHARD HOWARD LEAKER, of Montague Villa, Kingsdown Parade, in the
City and County of Bristol, Engineer, do hereby declare the nature of this inven-
tion 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 kilning malt and consists in an improved system of
effecting the same, and in buildings, and apparatus therefor.
According to this invention, two kilning floors are employed, one placed over the
other. The furnace is below the lower kilning floor and when the said lower floor
only is being used forkilning, the heat is directed to pass through the "slopes," or
TD B77

page_text: conical or tapered chamber, above the furnace to the underside of the floor, as is
usual; the widest part of the said chamber being immediately below the floor.
The heat passing through the. perforations in the floor permeates the grain in the
usual way and the fumes discharged escape by a chimney into which they are
directed by a conical hood fixed over the floor.
When the upper floor only is being used for kilning, a damper situated in a pipe
extending from the furnace to the chimney is opened and the heat, instead of
passing up through the chamber above the furnace, ascends in the said pipe whence
it is directed by a second damper into branch pipes which conduct it to the under-
side of the upper floor. After passing through the perforations in the upper floor
and through the malt thereon, the fumes escape through ventilators in the roof.
When kilning is required to take place on both floors, the heat is directed by the
dampers in such manner that the supply thereof to each floor is independent to that
of the other, the fumes from the lower floor being prevented from passing through
the upper floor.
In the accompanying sheet of illustrative drawings
Fig. 1 represents a vertical section and Fig. 2 a horizontal section of a malting
house constructed and arranged for kilning malt in accordance with this invention.
The section Fig. 1 is taken on the line a, a, Fig. 2, and the section Fig. 2 is taken.
on the line y, y, Fig. 1. In the example illustrated in the drawing the arrangement
is duplicated and it is to be understood that the following description applies equally
to both divisions which are precisely the same in all respects.
According to this invention two kilning floors a and b are provided, the kilning
floor b being above the kilning floor a; as shown. The furnace c is below the
floor a and when the latter floor only is being used for kilning, the damper d in the
tube e is closed and the heat from the conical furnace e passes up through
openings in the furnace crown into the "slopes" or conical chamber above the
furnace to the underside of the floor a, as is usual. The floor a is perforated in the
usual manner and the heat passing through the perforations permeates the grain
spread on the floor. The fumes escape by the chimney g into which they are
directed by the conical hood fixed over the floor.
When it is desired to use only the upper floor for kilning, the damper dis
opened and the heat ascends in the tube e from which it is conducted by the branch
pipes e to the underside of the upper floor b, the damper being closed. After
passing through the perforations in the latter floor and the malt spread thereon,
the fumes escape through ventilators in the roof.
When it is desired to use both floors a and b for kilning malt, both dampers d
and are opened and thus the supply of heat to each floor is independent, the fumes
or reek from the malt on the lower floor a being prevented from passing through
the malt on the upper floor b.
The central tube e aforesaid communicates at the lower end with a pipe or duct i,
Fig. 2, from which cold, dry, filtered air is supplied to cool the malt after it has
been kilned, or for the purpose of withering the green corn on the floors. Such
supply of air is controlled by a suitable damper k in the pipe i.
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 house or structure for kilning malt, means for conducting and diverting
the heat to the kilning floors so that the fumes from the malt under treatment on
the lower floor do not pass through the malt on the upper floor, said means
consisting of the covered conical furnace e with openings c' in the crown, the' central
tube e carried into a chimney such as y and fitted with dampers d and 1, and having
branch tubes e communicating with the space immediately above a hood such
ash, situated below the upper floor b, substantially as herein before described and
shown in the accompanying sheet of drawings.

page_text: 2. The provision in connection with the central tube e of a pipe or duct i com-
municating with the said central tube and fitted with controlling damper k from
which pipe or duct. i cold, dry filtered air may be supplied to cool the malt on the
floors above after the malt has been kilned, or for the purpose of withering the
green corn.
