Improvements in and Apparatus for Sterilising or Preventing
Fermentation or Acetification of Beers, Beverages, or the like.
We, PETER WILSON MAY of St. Margarets, West Heath Road, Child's Hill,
Middlesex, Esquire and BENJAMIN EDWARD REINA NEWLANDS of 27 Mincing
Lane in the City of London Analytical Chemist do hereby declare the nature
of this invention to be as follows :-
--
The object of this invention is to effect the sterilising of beers, beverages or the
like so that an aërated sterilized liquid or beverage is obtained.
According to this invention the liquid or beverage is aërated or charged with
gas (usually carbonic acid gas) and after that operation and whilst the said liquids
or beverages are contained in closed bottles or containers heat is applied to a
temperature requisite for sterilising the liquids or beverages so aerated or charged
with gas. The aërating or charging with gas may be effected in any suitable
acrating or charging apparatus. The heating may be effected in any suitable way
for instance by means of a liquid bath in which the bottles or containers are placed
and which is raised to the necessary temperature by any suitable heating device.
A suitable apparatus for the purpose consists of a vessel for holding the bottles or
containers the said vessel being preferably provided with superposed trays for
supporting the bottles or containers which trays can be readily inserted and
withdrawn with the bottles or containers which they support. It is preferable to
raise the
temperature gradually to the requisite degree and afterwards to lower it
gradually. The liquids or beverages may be sterilised before as well as after
aëration. As the heating of the bottles or containers and their contents increases
the pressure in the said bottles or containers and the liability thereof to rupture or to
leakage, the heating is effected whilst the bottles or containers are subjected to an
external pressure counteracting the internal pressure. This may be done by
closing the vessel containing the bottles or the like so that external pressure on
the bottles or containers is obtained for instance by pumping in air or water. The
degree of pressure can be readily ascertained by a pressure gauge fitted to the
vessel and there may also be provided a thermometer to ascertain the temperature.
The heating may be effected in any suitable way, for instance a coil of piping may
be provided communicating at one end with the upper part of the vessel and at the
other end with the lower part of the vessel heat being applied to the said coil.
The cooling down of the contents of the vessel for removal may be effected by cold
water but as it is desirable that too sudden change of temperature should not take
place the inlet for cold water may be arranged in such proximity to a passage
through which the hot water escapes that interchange of temperature is effected
between them before the cold water enters the vessel, for this purpose the cold
water supply pipe may be led through the interior of the hot water outlet.

Improvements in and Apparatus for Sterilising or Preventing
Fermentation or Acetification of Beers, Beverages, or the like.
We, PETER WILSON MAY of St. Margarets, West Heath Road, Child's Hill,
Middlesex, Esquire and BENJAMIN EDWARD REINA NEWLANDS, of 27 Mincing
Lane in the City of London Analytical Chemist 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 :-
The object of this invention is to effect the sterilising of beers beverages or the
like so that an aërated sterilized liquid or beverage is obtained.
According to this invention the liquid or beverage is aërated or charged with
carbonic acid gas and after that operation and whilst the said liquids or beverages
are contained in closed bottles or containers the temperature is raised to a degree
sufficient to sterilize the liquids or beverages so aërated or charged with gas. The
aërating or charging with gas may be effected in any suitable aërating or charging
apparatus. The heating may be effected in any suitable way for instance by means
of a liquid bath in which the bottles or containers are placed and which is raised
to the necessary temperature by any suitable heating device. A suitable
apparatus for the purpose is illustrated in vertical section in the accompanying
drawing.
It consists of a vessel A for holding the bottles or containers the said vessel
being preferably provided with superposed trays B for supporting the bottles or
containers which trays can be readily inserted and withdrawn with the bottles or
containers which they support as they are carried by a rod 6 connected with the
cover which can be raised and lowered by a chain as shewn. It is preferable to
raise the temperature gradually to the requisite degree and afterwards to lower it
gradually. The liquids or beverages may be sterilized before, as well as after
aëration.
As the heating of the bottles or containers and their contents increases the
pressure in the said bottles or containers and the liability thereof to rupture or to
leakage, the heating is effected whilst the bottles or containers are subjected to an
external pressure counteracting the internal pressure. This may be done by
closing the vessel A containing the bottles or the like so securely that external
pressure on the bottles or containers is obtained for instance by pumping in air or
water. The degree of pressure can be readily ascertained by a pressure gauge
fitted to the vessel and there may also be provided a thermometer to ascertain the
temperature. The heating may be effected in any suitable way for instance a coil
of piping may be provided communicating at one end with the upper part of the
vessel and at the other end with the lower part of the vessel heat being applied to
the said coil. The cooling down of the contents of the vessel for removal may be
effected by cold water but as it is desirable that too sudden change of temperature
should not take place the inlet for cold water may be arranged in such proximity
to a passage through which the hot water escapes that interchange of temperature
is effected between them before the cold water enters the vessel: for this purpose
the passages for the hot and the cold water respectively may be one inside the
other for instance the hot water outlet pipe c may be led through the interior of
the cold water supply pipe d as shewn clearly in the drawing.
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 we
claim is.
1. Sterilizing or preventing fermentation of beers beverages or the like by
exposing them to a sterilizing temperature after they have been aërated or

page_text: charged with gas and whilst they are contained in closed vessels or containers
substantially as hereinbefore set forth.
2. Sterilizing or preventing fermentation of beers beverages or the like by
aërating or charging them with gas and then subjecting them to a temperature
which is raised gradually to sterilizing point and afterwards gradually lowering the
temperature substantially as herein before set forth.
3. The sterilizing or preventing fermentation of beers beverages or the like by
aërating them or charging them with gas and then subjecting them to a sterilizing
temperature whilst they are in closed vessels or containers and with the application
of external pressure to the said vessels or containers substantially as and for the
purpose herein before set forth.
4. In the sterilizing or preventing fermentation of beers beverages or the like as
set forth in the preceding second claiming clause the combination with the vessel in
which the containers or vessels holding the liquids to be treated are heated of
passages for cold water and for hot water respectively in proximity to each other
to effect a transference of heat substantially as and for the purpose hereinbefore
set forth.
. Apparatus for sterilizing or preventing fermentation of beer beverages or the
like the said apparatus being constructed or arranged substantially as hereinbefore
described and illustrated in the accompanying drawings.
