METHOD AND ARRANGEMENT FOR INTRODUCING GAS INTO LIQUIDS BY
MEANS OF A NOVEL MIXER
The invention relates to a novel mixer by which gas is introduced into
liquids,
preferably C02, in water.
The invention furkher relates to an arrangement and a construction of the
novel
mixer. Beverages, in particular water and mineral water, but also refreshments
such as lemonade, fruit juices and liquids mixed with other flavoring agents
are
carbonized, i.e., mixed with C02 (carbon dioxide) to produce the impression of
freshness that is currently so desired. Addition of C02 can also improve stale
or
flat water yr water mixed with disinfectants.. Therefore, COZ is added to
water
(with or without mineral agents) in bottles or other containers and introduced
under pressure into liquids and, e_g., dispensed from so-called CO2
cartridges_
The purchase of carbonated water in bottle is complex and expensive in view of
the transports. The do-it-yourself preparation is also complicated as the C02
gas
in pressure containers has to be introduced into the water which then remains
under pressure in the containers.
The invention is based on the object to provide a novel mixer by which
carbonated liquids, in particular water, can easily be produced continuously,
whereby the CO2 consumption depends on the amount of supplied and tapped
water.

'The invention is attained by conducting the gas to flowing liquid and by
using the
novel mixer for attaining and optimum mixture.
According tQ a further embodiment of the invention, which has separate
inventive
status, for absorbing C02 and other gases, the novel mixture implements a very
high mixing quality (carbonization) at slight pressure conditions of liquids
and
gas.
According to a further embodiment of the invention, which also has separate
inventive status, the novel mixer is in a position to realize a constant
quality, for
example, soda water, provided that the water stream to the mixer is not
interrupted and the gas supply C02 is also ongoing in this case, whereby the
novel mixer runs better than all known systems which require very high
pressure
for the production of carbonated water.
A further embodiment of the invention, which also has separate inventive

application of the novel mixer may also be exploited for alcoholic beverages.
It
may be used for private households or industrial application.
In accordance with a further embodiment of the invention, which also has
separate inventive status, the novel SLS-mixer is used in agriculture and
gardening by using water, carbonized by the mixer, for fertilization and
watering
of fields and greenhouses.
A further embodiment of the invention, which also has separate inventive
status,
resides in the field of application in cleaning machines (carpet cleaning
machines). The mixer is integrated downstream of a pump which is connected to
a reservoir. Connected upstream of the mixer is the C02 introduction; thus,
carbonated water can be produced for the carpet cleaning.
According to a further embodiment of the invention, which also has separate
inventive status, the novel mixer is integrated in a washing machine. These
washing machines may be industrial or household washing machines. Water
required for the washing process is conducted together with C02 through the
mixer into the washing machine
A further embodiment of the invention, which also has separate inventive
status,
resides in the structure and the configur2~tion of the SLS-mixer. The novel
mixer
is comprised of individual mixing screens which abut one another depending on

the field of application. The number of mixing screens and the diameter as
well
as strength thereof depends on the task of the mixer at hand. This relates
also to
the mesh structure (throughput rate) of the mesh. Preferred materials include
VA-steel or plastics. The same effect could be attained with metal disks or
plastic disks having corresponding boreholes and same arrangement as in the
screens.
According to a further development of the invention, which also has separate
inventive status, the mixer is comprised of one or more parts and is identical
or of
similar configuration as the mixer described previously by me. Gas and liquids
can be mixed in a same quality with this mixer as with the afore-described
mixer.
According to a further advantageous configuration of the invention, which also
has separate inventive status, the novel mixer mixes in the high temperature
9 5 fluctuation range of water always at a same quality of soda water or other
beverages. Also the extremely small bubble formation of carbonic acid,
generated by this mixer in soda water and other refreshments, tastes extremely
pleasant. The high carbonization is characterized by the fact that the bound
C02
in water has small losses of unbound C02 after the mixing process. The release
of C02 is very low compared to other methods that carbonize water. This new
type of mixer exhibits superior properties to produce quality soda water with
little
pressure.

A further embodiment of the invention, which also has separate inventive
status
resides in the fact that the novel mixer can be made highly cost~efficient and
that
this mixer operates at slight counter pressure to hereby realize a calm flaw
behavior of the gas to be mixed with the liquid.
According to a further development of the invention, which also has separate
inventive status, the mixer may be comprised of spherical, conical or
cylindrical
components which are connected in a construction frame.
According to a further development of the invention, which also has separate
inventive status, the novel mixer is placed in a tube which has at the same
time a
connection for the liquid stream and the gas introduction. The tube has
further a
connection possibility for a metering station downstream of the mixing process
of
liquids and gas. This may also take place upstream of the mixer_ One or more
attachments are integrated in the tube for securement of the mixer. At the
same
time, the tube is so sized as to allow exploitation of the tube as reaction
time_ The
connection for the liquid and gas supplies can also be configured as
detachable
connection.
According to a further advantageous configuration of the invention, which also
has separate inventive status, the connection possibility for a gas container
{C02) is so constructed that a tine from the tube where the mixer is installed
has
a connection possibility to attach a gas container without any problem. This

connection from tube to container may be flexible. The connection for the gas
container is so constructed that only a licensed gas container can be attached
to
the tube for supply of gas to the mixer.
According to a further advantageous configuration of the invention, which also
has separate inventive status, the mixer is so constructed as to suit the
field of
application. The fact that there is a fixed setting of liquids and the
respective gas
means with respect to the liquids the flow rate and the liquid pressure at the
gas,
the volume flow amount and the gas pressure. The afore-stated conditions are
ensured by pressure reducers and volume flow valves. An optimum quality is
ensured as a result of the fixed setting of the pressure as well as the volume
flow
of the liquid and the gas. The mixer can also be used reliably in situations,
where no fixed setting is required.
The invention is not only directed to carbonization of water of any type. The
novel mixer can be used for all conceivable liquids and gas types_
The invention will now be described in more detailed with reference to
exemplified embodiments.
