The ~~e~allCy ofthe e~nomic~l value of a mineral-water used to produce w~ne or ~it-Ju~ee muccd-be~rerages and its inf~ Pncc on the taste of that drink is ~he reaSOn for the demand of ga .L..~ t b~ i and/or CQr~ Jm~rs to develop a method to produce d~ . hl~
CO2-~nn~hed ~fater for use w~th juicc--and/or ~nne-mixes that i~ d this mven~ion Closely related to this problem is to obtain a device that allows the procedure of the P~{ mcthod, as well ~s the com,~o..ents specific for this patent, required for such a device.
To pr~ducc soda water this invention pians to take water ~om the water supply, fee~l it mto ~ rnixing-~ank where it is ~;chcd with COl and then Lli~ sed fi-om a tap do~n Q~rrent The onl~r raw ~ . used in this method are tap water asld CO,-gas. Since tap water is ~ ." the costs for soda water in mi~c-bevesagc s with the method ;fL~ c1 in thi~s inven~on are L~ ~1i .he produced soda ~rater can also be served as is bc~ ,.,c it is from pure tap water and therEfore without harmfill s~lbst~n~.~.c The cost fi~or compared to store-bought mineral-watess is e~.ren g~ater.
An ~itionlo ~is ~ncthod would ~e to filter the tap water before the e~richment w~th CO2 to f iimin~f~ any odors or c,olors.
Tap water is in any ca~se frce of to~Qc subct~nc.es. however it could contain sccrc~ions from the pl..~ that may ~e noticed by people with ~ taste buds Withthefilterin~nlr~ allsuspended p~ticlesareret~nedsothatthe consistencyisvery pure It is ~ c~ d that thetapwater is coo1ed dov~n to a temperaturc of 2--lO
de~rees Celsius (35 6--50 de~
Fshrenheit~, ~referab~y 4--6 d~s Celsius (39 2--42.8 de rees 1~ ~ ~l,eit).
At this t~ LLure C0,~ has ~ts highest absol~Lion in water and that leads to a ver~
pnc~ efEect. ~so the soda water has an ideal ser~n~ t .~ Lure. .
Ihe p:ltf~rlt~3 method allows a ~rariation of the c~nG ~ ion of C0~ in the~ater by vaI~ati~g the ~ u~, ofthe C0~ a~conl.~lg to the Law of ~eD~y, w~ich rules tha~ the solubilit~ of gas at a co.~ al~lre l~i is propor~onal to ~e par~Ial y~ e of the gas above the solvent. With the pr~ ssure valve on the ~s bottle the ~c and also its a~sorption is controDablc Another possibilit~ to infl~ he C~2 ~0 ~ dLion is to add pure tap water to the produced soda water.
The de~nce dcs~ il,~ d above, t}~ aUows the continm~e production of soda water or soda- like water ~y gastrono~t~

FurtheImore the sn~xing tank lus an di~on~l conncctior~ to ~ E~ tar~

receives a s1~ffi~ nt supply i~fC02 and tap water so ~here is always cnough soda water 35 in the tank for pour~ng and sale 1~1 a very s~ort time the CO2 gas spreads out through the rnixing tanlc and therefore the t~p can be lef~ open for longer periods of ~ne.
To avoid the sea~ing CO2 throug~ the 40 m~x~ng-tar~c into the water supply the inventors placed a one-way valvcbetween the mix~ng tank and rhe ~v~ter supply. By usin~ a g~s~pht valve C02-gas ma~l not exit and pressure ~5 not lost.
45 ~ even more advantageous: ~,E,L.~ent is to use a cooling apparatus ahead ofithe mi7ung tank before the tap water is fed into th~nk This means the warer is cooled to an ideal temperature to absorb the COz and also h~ an idea~ selving t~elaL~ even before it reaches the mix~ ta~

the taste. Other s~-hct~nr~s such as chlorine or pathoge~c agents are hdd back It is f~ol r~ nrl~l to use a filtcr w~th an absorption chamber where ac~vats~d charcoal ennched with silver is used. Such filters rnay be eq~ pe~- with dev~ces to shut offthe water flow, when ~hc filter capacity is e~ stef-, th~t the b:~rlc-f~epf~ knows wllen it is time to change the filter. To L~,e a quick reFl -f~f-Tnf?-1t of the filter, valves are placed before and bfehind the fi3ter to stop water flovr, durulg the f~.hangTnfJ o~the filter.
The mixing-tank is the crucial part of this soda-water producing de~nce. It has a water connection.. ~hermore, the t~nk has a nozzle tO feed COl ~nto the tanlc that is connected to z tube. To avoid CO2 getting into the water inlet tube or w~ter into the ,gas bottle one-way valves are inSt~Ue~ The m~ba~g-tanlc m ~st be built so that there is al~vays sTTffif-if~nt ~ , to push the CO2 G~ ichcd water to the tap.
However the nozle to feed the CO2 into the tank should be so constructed as to avoid a CO, bubble b~lding in the conta~ner The fIter respectively the coolirlg apparatus are ~sually belo~ the tap that it is log~cal that the water inlet nIbe - should be located at the bottom ofthe rr~xin~ conta~ner. For the same rcasons the CA 02247088 l998-08-l9 O S
water drain c~ r~ should be placed at the top.

The ~~e~allCy ofthe e~nomic~l value of a mineral-water used to produce w~ne or ~it-Ju~ee muccd-be~rerages and its inf~ Pncc on the taste of that drink is ~he reaSOn for the demand of ga .L..~ t b~ i and/or CQr~ Jm~rs to develop a method to produce d~ . hl~

To pr~ducc soda water this invention pians to take water ~om the water supply, fee~l it mto ~ rnixing-~ank where it is ~;chcd with COl and then Lli~ sed fi-om a tap do~n Q~rrent The onl~r raw ~ . used in this method are tap water asld CO,-gas. Since tap water is ~ ." the costs for soda water in mi~c-bevesagc s with the method ;fL~ c1 in thi~s inven~on are L~ ~1i .he produced soda ~rater can also be served as is bc~ ,.,c it is from pure tap water and therEfore without harmfill s~lbst~n~.~.c The cost fi~or compared to store-bought mineral-watess is e~.ren g~ater.
An ~itionlo ~is ~ncthod would ~e to filter the tap water before the e~richment w~th CO2 to f iimin~f~ any odors or c,olors.
Tap water is in any ca~se frce of to~Qc subct~nc.es. however it could contain sccrc~ions from the pl..~ that may ~e noticed by people with ~ taste buds Withthefilterin~nlr~ allsuspended p~ticlesareret~nedsothatthe consistencyisvery pure It is ~ c~ d that thetapwater is coo1ed dov~n to a temperaturc of 2--lO
de~rees Celsius (35 6--50 de~

At this t~ LLure C0,~ has ~ts highest absol~Lion in water and that leads to a ver~
pnc~ efEect. ~so the soda water has an ideal ser~n~ t .~ Lure. .
Ihe p:ltf~rlt~3 method allows a ~rariation of the c~nG ~ ion of C0~ in the~ater by vaI~ati~g the ~ u~, ofthe C0~ a~conl.~lg to the Law of ~eD~y, w~ich rules tha~ the solubilit~ of gas at a co.~ al~lre l~i is propor~onal to ~e par~Ial y~ e of the gas above the solvent. With the pr~ ssure valve on the ~s bottle the ~c and also its a~sorption is controDablc Another possibilit~ to infl~ he C~2 ~0 ~ dLion is to add pure tap water to the produced soda water.

receives a s1~ffi~ nt supply i~fC02 and tap water so ~here is always cnough soda water 35 in the tank for pour~ng and sale 1~1 a very s~ort time the CO2 gas spreads out through the rnixing tanlc and therefore the t~p can be lef~ open for longer periods of ~ne.
To avoid the sea~ing CO2 throug~ the 40 m~x~ng-tar~c into the water supply the inventors placed a one-way valvcbetween the mix~ng tank and rhe ~v~ter supply. By usin~ a g~s~pht valve C02-gas ma~l not exit and pressure ~5 not lost.
45 ~ even more advantageous: ~,E,L.~ent is to use a cooling apparatus ahead ofithe mi7ung tank before the tap water is fed into th~nk This means the warer is cooled to an ideal temperature to absorb the COz and also h~ an idea~ selving t~elaL~ even before it reaches the mix~ ta~

Such filters rnay be eq~ pe~- with dev~ces to shut offthe water flow, when ~hc filter capacity is e~ stef-, th~t the b:~rlc-f~epf~ knows wllen it is time to change the filter. To L~,e a quick reFl -f~f-Tnf?-1t of the filter, valves are placed before and bfehind the fi3ter to stop water flovr, durulg the f~.hangTnfJ o~the filter.
The mixing-tank is the crucial part of this soda-water producing de~nce. It has a water connection.. ~hermore, the t~nk has a nozzle tO feed COl ~nto the tanlc that is connected to z tube. To avoid CO2 getting into the water inlet tube or w~ter into the ,gas bottle one-way valves are inSt~Ue~ The m~ba~g-tanlc m ~st be built so that there is al~vays sTTffif-if~nt ~ , to push the CO2 G~ ichcd water to the tap.
However the nozle to feed the CO2 into the tank should be so constructed as to avoid a CO, bubble b~lding in the conta~ner The fIter respectively the coolirlg apparatus are ~sually belo~ the tap that it is log~cal that the water inlet nIbe - should be located at the bottom ofthe rr~xin~ conta~ner. For the same rcasons the CA 02247088 l998-08-l9 O S
