An Improved Apparatus for Aerating, Purifying, or analogously
Treating Liquids, Fats, and similar Substances.
I, JOHN HAMILTON HUNTER, of Brooklawn, Stradbrook, Blackrock, in the County
of Dublin, Merchant, do hereby declare the nature of this invention to be as
follows;-
-
This invention relates to an improved apparatus for aerating, purifying or
analogously treating such articles as milk, cream, oils, liquid-butter and fats
spiritous liquors and the like, the object being to aerate, purify, cleanse and blend
or mature such liquids, and for the removal of deleterious substances contained
in them.
My apparatus consists essentially of a vessel preferably cylindrical in form,
having a conical or other shaped cover easy of removal and provided with suitably
glazed parts to allow the interior to be viewed, and also with a suitably arranged
outlet pipe, to carry off impure air or gases. In the lower part of the vessel is
placed either a perforated coil, or a perforated "box ring" for the admission of air
which is so arranged as to give a regular and general distribution. The centre
of the bottom of vessel within the coil or box ring" is perforated with a suitable
number of holes which are adapted to be opened or closed by means of a sliding or
revolving plate or its equivalent so that the bottom of the vessel can be opened
to allow impurities to be readily drawn off.
66
In, carrying out my process, I force the air through the liquid in the vessel by
means of a rotary air pressure fan or "blower" which may be worked by hand or
power and regulated by a graduating valve. When a perforated coil is used to
admit the air to the vessel I may employ a receiver or air chamber to regulate the
pressure.
In order to regulate the temperature of the liquid in the vessel undergoing
treatment, I provide round its upper part one or more perforated tubes into which
water of the desired temperature is passed, and out of which it trickles down the
outside of the vessel and is gathered and carried away by a suitably shaped lip
or channel at or near the bottom thereof.
In order that air may be passed through the liquid or substance to be treated
at the necessary temperature the pipes carrying or admitting air into the perforated
coil or box ring" preferably pass in any suitable form through one or more
oblong chambers adapted to contain hot or cold water as desired, or alternatively
cold water capable of being heated by steam. When rapid alterations of tem-
perature are required, I prefer pass the air through steam gas or heaters for
heating it and through ice box for cooling it.

An Improved Apparatus for Aerating, Purifying, or analogously
Treating Liquids, Fats, and similar Substances,
I, JOIN HAMILTON HUNTER, of Brooklawn, Stradbrook, Blackrock, in the County
of Dublin, Merchant, 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 an improved apparatus for aerating, purifying or
analogously treating such articles as milk, cream, oils, liquid-butter and fats
spiritous liquors and the like, the object being to aerate, purify, cleanse and blend
or mature such liquids, and for the removal of deleterious substances contained
in them.
In the accompanying drawing which illustrates this invention;-
Figure 1 is a view in side elevation of the apparatus,
Figure 2 is a view in sectional elevation of the chamber to contain the liquid,
fats or similar substances to be treated.
Figure 3 is a view in plan thereof, and
Figure 4 is a view in section on line a, a, Figure 2.
66
Throughout the views similar parts are marked with like letters of reference.
The apparatus consists essentially of a vessel A preferably cylindrical in form,
having a conical or other shaped cover B easy of removal and provided with glazed
openings to allow the interior of the vessel to be viewed, handles b¹ for lifting
and an outlet pipe 62 to carry off impure air or gases. At the bottom of the vessel A
is an annular chamber A' which I call a box ring" for distributing the air to be
forced through the vessel, the upper side of the box ring" being perforated for
the purpose. The bottom of vessel A inside the "box ring" A' is perforated with
a suitable number of holes which are adapted to be opened or closed by means of a
suitable slide C or its equivalent to allow the impurities settled at the bottom of
the vessel to be drawn off. As an alternative construction a perforated coil may
be used instead of the "box ring" A¹.
"
In order to regulate the temperature of the liquid fat or other substance under-
going treatment in the vessel A, the said vessel is provided around its upper part
with a perforated tube D into which water of the required temperature is allowed
to flow from any suitable source, and out of which it trickles down the outside of
the vessel, a suitable trough E being provided near its bottom to gather and
carry it away.
In order that the air passed through the liquid or substance to be treated may be
of the necessary temperature, the pipe F conveying it under pressure from its
source which may be an ordinary rotary air pressure fan or blower-to the "box
ring" A or its equivalent is passed in any suitable form to increase its super-
ficial area through one or more oblong chambers such as G connected with a hot
and cold water supply by pipes H and J each of which is provided with a suitable
controlling cock or valve and provided with a draw off cock g. Instead of hot
water a supply of steam may be used to heat the cold water.
When rapid alterations of temperature are required I employ separate chambers
for heating and cooling the air employing steam or gas for heating and ice for
cooling.
In the pipe F connecting the pipe F in the chamber G with the "box ring" A¹
or its equivalent is provided a thermometer f and a stop valve or cock f¹.
To provide water under pressure when required during any period of the opera-
tions and also to facilitate the cleaning of the vessel A a pipe K connects the cold

page_text: water supply pipe J with the pipe F between the stop valve or cock ƒ¹ and the
vessel A the said pipe K being provided with a stop valve or cock k.
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 improved apparatus for aerating, purifying, or analogously treating
liquids, fats and similar substances, substantially as herein described and illus-
trated by the accompanying drawing.
(2) An apparatus for aerating, purifying, or analogously treating liquids, fats
and similar substances, consisting essentially of a vessel such as A having a per-
forated annular chamber such as A or its equivalent at its bottom adapted to act
as an air-distributor, perforations in its bottom within the annular chamber or
its equivalent adapted to be closed by a slide or its equivalent, a suitable closing
cover having glazed spy holes, lifting handles and an outlet pipe, a perforated pipe
or chamber round its outer wall near its upper end and a trough or its equivalent
round its outer wall near its bottom, as and for the purpose set forth.
(3) In combination with the apparatus specified in Claim 2, of means for varying
the temperature of the air admitted to the chamber A¹ of the vessel A, as set forth.
(4) In combination with the apparatus specified in Claim 2, of means for the
delivery of air under pressure to the chamber A¹ of the vessel A, as set forth.
Dated this 16th day of October 1899.
