PROVISIONAL SPECIFICATION.
An Improved System of "Pneumatic Malting."
I MORRIS PAUL HATSCHEK of 56 London Road Ipswich in the County of Suffolk
Chemical Engineer do hereby declare the nature of said Invention for "AN IMPROVED
SYSTEM OF PNEUMATIC MALTING" to be as follows:-
The barley is first cleaned and steeped as usual and then put into tanks of about
4' high made of cemented brick work stone wood &c. destined for growing. These
tanks have double bottoms the upper one or false bottom being made of wire-cloth,
perforated plates or similar material, so as to allow the air to pass from underneath
into and through the couch of barley which can be from two to about three feet high.
From 20 to 30 hours after the barley having been put into these tanks it begins to
germinate and when the temperature of the bulk has risen to 55° or 60° Fahrenheit
the introduction of air can be started.
The air is conveyed by blowers ventilators &c. and passes first a washing apparatus,
in which it is brought in contact with pure (disinfected) water of a suitable temperature,
to become purified and saturated with water to the right degree of dampness: the air
is also ozonized in the said apparatus or in a special vessel, through which it is
conveyed, passing over sticks of phosphor or otherwise, to ascertain its purification
from unsound ferments or spores and to invigorate the growth of the barley.
The introduction of air is regulated so as to maintain the right temperature and
proportion of humidity of the barley (green malt) and constantly to take off the
carbonic acid gas developed by vegetation, and is performed by the air entering at
the bottom of the tank and leaving it at the top.
The growing malt can be turned from 10 to 10, or from 12 to 12 hours only and
this can be done by handwork or by a turning machine.
Should the growing malt become too dry, it could be moistened, especially when
turning it over, through roses through small holes or dispersers (Pulverizers) System
Körting and others.
The growing tanks can be left open or covered by frames, over which tinned or
galvanized wire cloth or other suitable material is spread, to keep off dust and other
impurities.

-COMPLETE SPECIFICATION.
An Improved System of "Pneumatic Malting."
I MORRIS PAUL HATSCHEK formerly of 56, London Road Ipswich in the County
of Suffolk Chemical Engineer now residing at Ashley House Albert Bridge Road in
the County of Down, do hereby declare the nature of the said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
•
.
The barley or other grain is first cleaned and steeped in cold water as usual and then
put into tanks of about 4 feet high made of cemented brickwork stone wood etcetera.
These growing tanks are provided with double bottoms, the upper or false bottom
being made of wire cloth, perforated plate or similar material so as to allow the air to
pass from underneath into and through the couch of barley etcetera which can be
from two to about three feet high. After 24 to 36 hours from the time when the

page_text: barley et cetera was put into the tanks, it begins to germinate and when the temperature
of the bulk has risen to 55° or 60° of Fahrenheit, the introduction of air can be
started.
The air is supplied by blowers or fans et cetera and passes first a washing apparatus
in which it is brought in contact with pure (disinfected) water of a suitable temperature,
so as to become purified and saturated with water to the right degree of dampness.
The air is also ozonised in the said washing apparatus or in a special vessel, through
which it is conveyed by passing over sticks of phosphor, or by electric currents or
otherwise, to ascertain its purification from unsound ferments or spores (lactic
acid et cetera) and to invigorate the growth of the barley or other grain at the same
time.
The supply of ozonised air is regulated so as to maintain the right temperature and
the most suitable proportion of humidity in the barley et cetera (green malt) and
constanly to take off the carbonic acid gas, developed by the vegetation, by the air
entering at the bottom of the tank and leaving it at the top.
The growing malt can be turned from 10 to 10 or from 12 to 12 hours only. And this
can be done by hand or by a turning contrivance, as known and in use for growing
malt in tanks as well as for malt being dried in kilns.
Should the growing malt become too dry it could be moistened especially whilst
turning it, through roses with small holes, or by dispersers (Pulverisers) system
Koerting and others.
The growing tanks can be left open or be covered by frames over which tinned or
galvanized wire cloth, or another suitable material is spread to keep off dust and other
impurities.
If the turning of the green malt is to be done by hand, small partitions can be
made on two ends of the growing tanks of wood or iron plate et cetera to be put on and
removed alternately, so as to facilitate the turning and shifting of the growing malt
from one side of the tank to the other.
DESCRIPTION OF THE DRAWINGS.
(a) Washing apparatus for air-(6) Entrance of air (mainpipe from blower)-
(c) Entrance of water-(d) Taps for distribution of air-(e) Outlet of air-(f) Run off
of water (ch) Chamber for ozonising the air-(9) Pan or dish for phosphor-sticks-
(H) Main pipe conveying ozonised air-(h) Air pipe leading to growing tank-(i) Air
pipes leading to partitions of growing-tanks-(k, k.) Growing tank-(1, 1) perforated
(false) bottom of growing tank-(m, m) Partitions of wood or iron plate, to be put or
removed alternately for turning and shifting the growing malt.
The air washing apparatus consists of a. long cylinder (A) and two end compart-
ments (c, c.)
The atmospheric air enters into the bottom compartment and rises up into the
cylinder through a number of copper taps (d, d.)-All these taps are protected by
small copper shades so as to keep the water from running down into the bottom part
of the apparatus.
The water is pressed into the top compartment which communicates with the
cylinder by a pipe (p) so as to be under the same pressure, and falls down through the
perforated copper plate, which separates the top part, and the cylinder. The waste
water runs off through a siphon (f) the length of which can be adjusted according to
the pressure of the air. The air is purified by the spray of water, and leaves the
cylinder by the main pipe (e) after having been ozonised in the chamber, ch, by passing
over a dish (9) containing sticks of phosphorus lying in water.
Having thus described and ascertained the nature of my said invention and the
manner in which the same is or can be performed what I claim as new and
desire to be secured to me by Letters Patent is :-
1. The preparation of purified and ozonised air for Pneumatic Malting as
described.

page_text: 2. The construction of an air washing and ozonising apparatus for the said purpose
as described and illustrated.
3. The protection of pure green malt free from lactic acid and other unsound
ferments by means of purified and ozonised air as described herein.
