Improvements in and connected with the Treatment of Brewers'
Grains and similar Materials.
We, LUDWIG EGYEDI, Distiller, JOSEF WEISS, Works Director, JOSEF
POPELKA, Chief Engineer, and ANTON MLADY, Foreman, all of Neupest, in the
Kingdom of Hungary, 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 the treatment of brewers' grains or spent malt and the
like materials for the removal therefroin of wort or other fluids, the process and
apparatus being equally applicable for the treatment of pulpy feed-stuffs for cattle.
According to this invention, the materials to be treated are arranged above a
filter and the space below the filter is exhausted of air, thus ensuring the quick
removal and filtration of the fluids mixed with the materials.
We will describe our invention more particularly with reference to the accom-
panying drawing which shews one of the filtering chambers and connections in
sectional, and one in side elevation.
The apparatus consists of a vessel A, containing the horizontal filter B, which
may consist of wire gauze and cloth, or other suitable material such as is commonly
used for similar purposes, supported by cross bearers. The lower part of the
vessel is provided with a conical bottom, which serves to drain the filtrate into the
pipe E. The outlet pipe E is enlarged as indicated by the drawing, and in
the enlarged part there is the vertical wall e, which stops at some distance above
the lower end of the tube. A lateral pipe F, connects the pipe E with an air pump
or exhauster. The lower end of the pipe E is closed by the valve h, which is kept
in place by the weighted lever H. Two or more sets of the apparatus may be
connected together and may be supplied through the common conduit G, through
the branches g.
In using the apparatus, the wet materials are placed or conducted into the
space C, above the filter B. The suction tube F is then connected with the air
pump and thus air is drawn out of the space D, below the filter. The atmosphoric
pressure, then acting upon the surface of the wet materials, forces the liquid parts
of the materials through the filter into the space D, whence the liquid flows into
the tube E, in the lower part of which it collects.
When a certain amount of the
liquid has collected, its weight opens the valve h, permitting so much of the liquid
to escape as is in excess of the weight upon the valve, after which the valve again
closes without ever allowing all the liquid to be discharge, so that the valve is
always sealed.
In the case of feed stuffs, the materials are subsequently removed from the filter
and are dried naturally or by artificial heat.
The fluid drawn from the filter may be utilised by mixing it with the wort of
other liquor originally obtained from the material.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what wo
claim is:-
1. The herein before described method of separating fluids and liquors from
brewers' grains and similar materials substantially as and by the meaus set forth.
