AN IMPROVED APPARATUS FOR HEATING OR BOILING BREWERS' WORT AND OTHER LIQUIDS
Year: 1884

page_text: I HENRY JOHN WORSSAM, of Wenlock Road, City Road Basin, St Leonard's
Shoreditch, Brewers' Engineer, do hereby declare the nature of my said invention
for "AN IMPROVED APPARATUS FOR HEATING OR BOILING BREWERS' WORT AND
OTHER LIQUIDS," to be as follows:-
:-
This invention relates to beating or boiling water or wort, more particularly in
breweries.
In carrying my said invention into practice, instead of the ordinary coil of
pipes, placed horizontally, in the brewing vessel, I make a heater consisting a
drum, filled with steam, fitted with a number of tubes, extending from the top to
the bottom of the drum. This drum is placed on the bottom of the tank, if
possible, with the tubes placed vertically, or thereabouts; they may be bent at the
bottom, to allow the liquid to enter easily or they may be perfectly straight.
The drum must, of course be rather less in height than the depth of the liquid to
be heated or boiled.
In using vertical tubes, or nearly so, I obtain a much more rapid circulation,
and the tubes being upright, or nearly so, the whole of the heating surface is
utilized, as there is no condensation around them; the condensation being at the
bottom of the drum, and free to get away.

In order that my said invention may be more fully understood and be more
readily performed, I will explain the same with the aid of the accompanying
drawing, which forms part of this specification; reference being made thereto by
the numerals and letters marked thereon; the same index numerals and letters,
indicate the same parts of the apparatus in each figure of the said drawing.
Fig. 1 shows my improved heater, adapted to a brewer's copper, for boiling
wort.
Fig. 2 shows the said heater, adapted to a brewer's ordinary mash tun, and an
ordinary mashing machine.
Fig. 3 shows the heater adapted to a wooden vessel, for heating water, for
brewing and other purposes.
Fig. 4 is a plan of the heater, as shown in fig. 1.
Fig. 5 is a plan of the heater, as shown in fig. 2.
In carrying my said invention into practice; instead of the ordinary coil of
pipes, placed horizontally in the brewing vessel; I use a heater, consisting of a
drum a, charged with steam, having numerous tubes fitted therein, extending from
the top to the bottom thereof, at a slight inclination; the drum standing on end
a few inches from the bottom of the vessel, either on legs or upon a block c.
The required steam is supplied by a pipe 6 or pipes passing through the said block
into the drum; the condensed steam is passed away by a similar arrangement.
When the vessel is filled with water or wort, above the top of the drum, and the
steam is turned into such drum, it causes a very rapid circulation therein, as
the heated liquid rises through the tube at a great pace, until it is boiled.
In using vertical, or nearly vertical tubes, I obtain a much more rapid circulation
and, the tubes being upright or nearly so, the whole of the heating surface is
utilized.
When it is required to run wort out of the copper, or other vessel, the hops are
kept back by the perforated draining plates c. These draining plates are generally

page_text: put into another vessel, but I consider, my method such an improvement, that
I purpose making a claim for it; inasmuch as the liquid percolates through the
hops, and is boiled over and over again, passing each time through the hops;
whereas, if the hops are allowed to rest on the bottom of the vessel, this does not
necessarily take place.
For heating water, not required to be boiled, for brewing purposes, I adapt my
improved heater to a wooden vessel (fig. 3). The difficulty that brewers have
to contend with at present is, that the temperature of the water, in ordinary
boiling, varies very considerably at the upper and lower part of it. I avoid this
difficulty, by placing over my improved heater a disc d, flat or conical in shape,
which does not allow the heated water to rise directly to the surface, but causes
it to go out sideways; thus heating the water more equally throughout.
For a brewer's ordinary mash-tun, I adapt my improved heater a as shown in
fig. 2; with an ordinary mashing machine; e being the perforated, draining plates,
so that the wort, whilst mashing, can be increased in temperature, which, at present,
is a difficult process; unless a steam coil-pipe is used, and even that is generally
found to be in the way.
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
Firstly The method of heating brewers' wort, and other liquids, by means of
a vertical, or nearly vertical drum, with pipes or tubes fitted therein; substantially
as described.
Secondly The method of draining the wort from the hops, by means of per-
forated plates; substantially as described.
Thirdly the method of making the general temperature of liquids in a vessel
more equal, substantially as described.
