Improved Means and Apparatus for Rousing, Aerating, and
Attemperating Brewers' Worts during the Process of
Fermentation.
I, CHARLES HENRY JOLLIFFE, of Olive Mount, (St. Anns) St. Helens.
Lancashire, Brewer, 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 a novel construction or arrangement of apparatus
for rousing, aerating, and attemperating brewers worts during the
fermentation.
process of
For the purpose of my invention, I employ a perforated or wirework tray on
the wort receiving or fermenting vessel, and in connection therewith I use a pump
for taking the wort from the tank and feed it on to the tray, on which it spreads
itself and percolates through in a series of fine streams, or as from a rose. The
yeast formed flows into a funnel, and thence into a collecting tank below.
Any number of trays and tanks may be fitted under the same roof, and all. the
pumps (which are only worked at intervals) can be driven direct from an overhead
or other shaft.
The fermenting vessel for receiving the wort is furnished with the usual
attemperating coil or piping, and the tray or trays may be of any desired
shape.
The annexed drawings show my invention.
Figure 1 is a sectional end elevation. Figure 2 a part plan view of a fermenting
house of a brewery with the trays and accessories in position.
A, A, are trays with perforated or open meshed bottoms on the fermenting
vessels B, B, C, C, being the attemperating coils or pipes therein. D is a draw off
pipe. E, the pump. F, F, the pipes for discharging or feeding the wort on to the
trays. G is the pulley. H, the driving shaft, and I the strap. J, the funnel in
the fermenting vessel for the flow of yeast down pipe K into yeast tank L.
The holes in the tray are of suitable sizes to carry the whole of the liquid which
is delivered into the tray from the suction pipe of the pump and which is dis-
tributed on the top of the yeasty head in the fermenting vessel, and according to
the length of time the pump is driven, this circulation of the wort is more or less
accomplished.
The invention is specially intended for those brewers who use slow or medium
yeasts but is applicable to all breweries where increased rousing and aeration of
fermenting worts is desired as it effects a perfect assimilation of nitrogenous matter
in the one case, and satisfactory assimilation or elimination in the other.
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 :-
1. The improved means and apparatus for rousing, aerating, and atteinperating
brewers worts during the process of fermentation, as herein before described and
substantially as shown by the annexed drawings.
2. In connection with the means for rousing, aerating, and attemperating brewers
