PROVISIONAL SPECIFICATION.
A New or Improved Apparatus for Pneumatic Malting.
I, CHARLES HUELSER, of the firm of Huelser & Co. of 142 Fleet Street, in the
City of London, Patent Agents, do hereby declare the nature of this invention, a
communication to me from abroad by Johannes Kuntze of Nordhausen, in the
Empire of Germany, Manufacturer, to be as follows :-
The object of this invention is an apparatus serving simultaneously for washing,
steeping and germinating the grain. The apparatus essentially consists of a
longitudinal receptacle having an air-tight fitting cover and funnel-shaped bottom
with flap and enclosing a perforated drum which contains a concentric perforated tube
closed at one end and communicating at the other end with an adjustable suction pipe,
while the receptacle is provided at one end with an air-inlet pipe and distributing
plate and at the bottom with a pipe and three-way cock for the admission and discharge
of water.
The new apparatus works as follows:
The malting material having been filled in to the drum, a quantity of water sufficient
to well cover the grain is admitted through the water pipe referred to. Subsequently
the drum is set in slow rotation by means of a convenient gear and transmission
device and, when the grain is in a state of steeping maturity-which is attained in a
very uniform manner by this process, the water is let off and the receptacle closed.
Cool moist air is then admitted from a suitable generator while simultaneously air is
removed through the suction pipe from the concentric tube by means of an aspirator,
the entering air being deflected and distributed in the receptacle by aid of the
distributing plate mentioned above. The germinating material is thus, uniformly
cooled while the carbonic acid generated is removed with the suction air and the
germinating grain prevented from growing together by the continuous revolution of
the drum.
A sufficient sprouting of the material having been attained, the cool moist air is
shut off by means of a suitable slide; atmospheric air is then drawn through the
material by removing the cover of the receptacle and subsequently the apparatus is
emptied through the flap at the bottom.

COMPLETE SPECIFICATION.
A New or Improved Apparatus for Pneumatic Malting.
I, CHARLES HUELSER of the firm of Huelser & Co. of 142 Fleet Street in the
city of London, Solicitors of Patents, do hereby declare the nature of this invention,
a communication to me from abroad by Johannes Kuntze of Nordhausen in the
Empire of Germany, 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 the devices for pneumatic malting and has for its purpose
to unite the appliances for washing, steeping and germinating the grain in one
apparatus which is moreover provided with a peculiar contrivance allowing moist
and cool air to be passed through the germinating material according to requirement.
Referring to the accompanying drawing,
Fig. 1 is a longitudinal vertical section.
Fig. 2 a vertical cross section of the improved apparatus, and
Fig. 3 is a cross section, on an enlarged scale of a detail thereof.

page_text: The receptacle W, having a funnel shaped bottom, contains a perforated drum T
which is lodged in the sides of the receptacle and provided with a cover adapted to be
turned up.
After the grain to be malted is filled into the drum T and a quantity of water,
sufficient to well immerse the grain admitted through the pipe r which is fitted with
a three-way cock h, the drum T is set in slow rotation.
The grain having attained steeping maturity-which is produced very. uniformly
with the improved process, the water is allowed to flow off through the pipe and
the receptacle W closed with an air-tight fitting cover D. Subsequently water is
admitted into the pipe N which is provided at the top throughout the receptacle D
along its inner sides and has numerous fine perforations from which the water
descends in the form of spray and penetrates through a ring or layer n made from
wire gauze and covering numerous perforations provided in the sides of W. While
simultaneously air is removed through the tube M communicating with an aspirator,
from the perforated tube R which is concentrically arranged within the drum T, air
flows in through the apertures covered by the wire gauze ring n and, penetrating the
moist gauze and the spray, is cooled and moistened. The tube R is closed at one end
and, with the other end, revolubly lodged and packed in the side of the receptacle W
so as to open into the tube M.
The moist and cool air is uniformly distributed within the receptacle and,
penetrating the germinating material, cools the same and carries off the generating
carbonic acid.
The revolution of the drum T causes its contents to be in continuous movement,
thereby efficaciously preventing the germinating grain from growing together.
When the material has sprouted sufficiently, the admission of water to the pipe
is discontinued, the cover D removed and atmospheric air drawn by suction through
the material. The turn slide S¹ on the tube M serves for regulating the suction,
while the overflow pipe A, provided with a cock is destined to remove the water
arriving from the pipe N, and prevent it from rising within the bottom of the
receptacle W to the drum T.
The malt is removed from the apparatus by opening the flap V of the receptacle W
and allowing it to fall into a van or the like placed underneath.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is:
In an apparatus for pneumatic malting which has a perforated drum encased in a
closed receptacle and serving to contain the germinating material, the device for
drawing moist and cool air by suction through the germinating material characteristic
by a water pipe N placed along the inner sides of the receptacle W, and from the
perforations of which a fine spray passes through the wire gauze ring n, whereby the
air drawn in by means of an aspirator connected with the tube M is moistened and
cooled by the air entering through the apertures covered by the gauze ring n,
substantially as illustrated and described.
