I, HERMANN HACKMANN, Manufacturer, of Mellrichstadt, Germany, 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:-
Barley, wheat and other cereals to be steeped has hitherto simply been watered,
in the vessel or cistern by introducing the necessary water from beneath or from
above and letting it out in the same manner.
According to my invention, on the contrary, the vessel is furnished with a double
perforated bottom A, see Figs 1-3 of the annexed drawings, and water is caused
to flow alternately from below and from above through the pipes B and D, and
compressed cold air or warm air according to necessity is introduced from beneath
through the pipe E, whereby the impurities sticking to the grains are loosened and
subsequently removed by repeatedly renewing the water. For causing the dirty
water to run off quickly, the vessel is provided at the outer wall, at suitable
intervals, with outlet tubes F, the grains being prevented from getting through the
tubes by sieves S. Thus the water does not penetrate the whole layer of the
sprouting material, but is more rapidly brought outside. In the case that a per-
forated tube G, Figs 1 and 2, is placed above the vessel, and moves circularly, while
the water runs in, this tube acts as a rose or spray producer, and during this
wetting atmospheric air is admitted from beneath through the tube E. Thus water
is saved, but nevertheless the purpose of steeping is perfectly attained, and the
degree of preparation and of sprouting may be altered at pleasure.
With rectangular vessels, Fig. 3 and 4, the inlet tube moistens the sprouting
material, instead of by circular motion, by horizontal forward and backward motion,
by the aid of the rolls H turning on the tube G and running on the rim of the
vessel; the forks J slide also on the rim, but are secured to the tube G, and the
elastic hose K forms a connection with the stationary water supply pipe.
The sieves A may be horizontal or (if the lower end of the vessel is narrowed)
inclined and are parallel to the bottom of the cistern.
The oblique arrangement, Figs 1 and 2, may also be applied to angular vessels,
Fig 3 and 4, for the purpose of causing the barley to run out by itself.

page_text: The valve L, which serves for the outlet of the barley, is movable from underneath
and allows the barley to escape through the outlet M. If the water is admitted
from beneath a three way cock N, or a second valve, and pipe P may be employed
to discharge water at the bottom, the discharge pipe receiving also the water
flowing out at F into the pipe R.
The air-inlet, if air is pressed in, or air-outlet, if air is sucked, is arranged under
the sieve bottom on either side. This arrangement is of importance, as it enables
the temperature to be regulated in winter as well as in summer, in a most sensitive
manner by supplying (under pressure) or withdrawing at will hot or cold air.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The process of washing barley or other sprouting material, while in the
steeping cistern, by the combined supply of compressed air or withdrawal of air,
and admission of water from the top or from the bottom.
2. A steeping cistern, having a perforated bottom A, an air pipe E, water outlet
Pipes F and P, and spray-producing or distributing pipes G, substantially as and
for the purpose described.
