COMPLETE SPECIFICATION.
Improvements in Malting Apparatus.
I, FRANZ BOLLMANN, Director of the " Landsberger Maschinenfabrik" of
Landsberg near Halle, in the Empire of Germany, do hereby declare the
ature 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 a pneumatic floor malting device and has for its purpose
o conduct the air, previously brought to the corresponding degree of moisture and
heat, under pressure and uniformly distributed to the grain to be treated.
Referring to the annexed drawings, Sheets I and II
A
Fig. 1 is a vertical section of the improved apparatus along lines A B and C D
Fig. 6 represents a detail.
The prepared air is drawn in at a by the ventilator band driven into the main
channel, which is widened at d and branches off into auxiliary channels ef. This
is repeated at d', where auxiliary channels elf are provided, and as many times as
divisions are to be successively arranged. Each auxiliary or division channel has
an air-tight closing door Fig. 5 and an air-moistening apparatus g is provided in
each space d d¹.
From each division channel ef extend laterally the distributing channels h, cach
of which is covered by an angle iron m provided in its whole length with per-
forations n, the joint cross section of which corresponds to the capacity of the
ventilator b.
Said angle irons also serve as supports for the malting floor s consisting of per-
forated sheet metal. Beside and between the angle irons m flat spaces are
formed which are covered by the perforated floor or bottom s.
The air penetrates the more uniformly through the grain brought on the sieve
bottom, the better it can distribute itself in the channels ef and hand k. Each
division can be closed and excluded from the work by means of the corresponding
door e; it can be independently emptied and worked afresh.
Moreover each germinating compartment can be cleaned independently during
work. For this purpose each channel is slightly inclined in the direction opposed
to the air current and at the lowest point of each division channel is provided a
discharge opening p adapted to be closed by a lid, flap, valve or slide and being in
connection with accumulating channels or tubes q. r.
After closing the door e and emptying the respective compartment the latter is
rinsed with sufficient water to remove all dust and other impurities through q r.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1) A pneumatic floor malting device consisting of hurdles or sieve bottoms
resting on angular perforated coverings of distributing channels, which branch off
from division channels communicating with a main channel, in combination with a
ventilator which is so placed as to allow pressure air to be driven into the whole
channel system, substantially as illustrated and described.

page_text: 2) In the pneumatic floor malting device forming the subject of Claim 1, the
application of doors e adapted to be closed air-tight and of discharge openings P,
substantially as illustrated and described.
