Improvements in or relating to Apparatus for Drying Malt.
A communication by Louis A. HENZE, of Detroit, in the County of Wayne and
State of Michigan, United States of America, Maltster.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool, and 6 Bank Street, Manchester, both in
the County of Lancaster, 118 New Street, Birmingham in the County of Warwick,
and 31, High Holborn in the County of Middlesex, Civil 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 relates to malt dryers, and has for its object an improvement in
buildings in which malted barley or other maited grain may be dried rapidly and
perfectly, without the usual labor of handling and otherwise treating the same.
In the drawings,
Figure 1 is a cross section of the building and appliances contained therein;
Figure 2 is a sectional, longitudinal view of the main shaft of the dryer.
A, indicates the walls of the building which is in the form of an ordinary rectangular
building provided with a gabled or hip roof, with a suitable chimney orifice.
Centrally through this building extends a shaft B terminating at its ends with
bearings b b which are held in suitable boxes supported in the main walls of the
building, or in any other suitable way. The shaft B supports a number of
rectangular boxes, the upper and under walls of which are made of perforated
material having perforations so coarse that heated air would pass through them,
but so fine that the malted grain would not pass through. This may be of
perforated sheet metal, or woven material, or any similar suitable substance. The
ends of the several boxes are supported and held in position by a ring d, and there
may be of these rings (each of which is concentric to the main shaft B) any
suitable number to furnish proper support to the boxes c c. The ends of the boxes,
by which is meant those portions which are parallel with the main shaft B, and join
the perforated upper and under sides, are made in the form of doors e e, hinged to the
under piece so that they may be readily opened, as indicated at Figure 1
at e and e, and they are also provided with proper hasps and catches to hold
them shut at times when it is not desired to have them open. Through one of the
side walls of the building there is, near the top, a shute S and an inspection door, or
a number of inspection doors t, and on the same side of the building near the
The door e³,
bottom of the wall, there is an exit shute R and an inspection door r.
when open as shown in Figure 1, forms a prolongation at the bottom of the shute S,
and guides grain thrown into the shute S directly into the box c. The door e',
when in the position indicated in dotted lines in Figure 1, forms a continuation of the
bottom of the box c and directs the out-flowing grain from box c into the delivery
shute R. ff indicate two driving rollers suitably mounted on framework in the
building, and one of which at least, receives motion from some external source, as
the driving wheel F, shown in Figure 2. Motion communicated to these driving
wheels, acting by friction on the rim d, serves to rotate the drying boxes cc on or with
the shaft B so that both sides of the boxes c c are successively brought and repeatedly
brought, if desired, next to the top of the furnace G.
HH indicate side guards secured to the walls of the building and extending for
about 90 degrees into close contiguity with the paths of the ends of the drying
boxes c, c, the purpose of these guards being to prevent the rising heat from passing

page_text: between the ends of the boxes and the walls and compelling it to pass through the
contained material. The doors r and t furnish a ready access to the interior of the
building at a place such that the contents of the boxes may be inspected at any time,
and the flap doors e¹ e2 may be opened or closed as desired."
The boxes c c may be opened from one end to the other, giving free passage-way to
the material, or they may be closed by cross partitions around the shaft, as indicated
in Figure 1, it being immaterial to the successful working of the devices, whether
there be free passage-way to the material clear across the box, or only part way
across it.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
1. In a dry house for malt, the combination of a central shaft, drying boxes
extending radially from the shaft, provided with perforated enclosing walls paralle!
with the radial line from said shaft and with doors at the ends of said boxes adapted
to form continuations of said enclosing walls, and a guarding partition adapted to
direct the heat through the drying boxes, substantially as described.
2. In a dry house for malt, the combination of a central shaft, drying boxes
extending radially from the shaft and provided with perforate enclosing walls parallel
with the radial lines from said shaft, and with doors at the ends of said boxes adapted
to open outward as extensions of the box sides, an inlet spout adapted to deliver into
the open end of a box when near the top, and an outlet spout adapted to receive and
conduct the outflowing malt from a box when near the bottoin substantially as
described.
