Description
This invention relates to a process for producing vodka and to an appara-tus for producing vodka usiny tha-t process.
Vodka is a drink of some considerable antiqui-ty, usually produced by mixing ethyl alcohol oE high purity with soEt water. ~ charcoal treatmen-t Eor filtration and absorp-tion oE color and Elavour is common and may be required in some countries, Eor example Canada. In some countries in Europe small amounts of minera]s may be added and even in some circumstances a limited amount of sugar. Several brands of vodka are based on a particular kind oE mineral~ resem-bling the early days of production of vodka where, for example, the water of a certain area would impart a certain Ela~our to vodka from that area.
It is now common in producing vodka to carry out a second distillation or rectification oE the alcohol and water to get a more intensive mixing oE the two preclominant ingredients and to Eacilitate the formation of any compounds that may be Eormed, for example hydra-tes of ethyl alcohol.
~0 By second distillation is meant a distillation subsequent to the distillation by which the alcohol is formed, a process common to all liquor-producing processes. This hydrate is better formed during the gas phase than in -the liquid phase because of the higher temperature. The idea of introducing the additlonal rectification, that is subsequent to -the distillation by which the alcohol in the vodka is produced, is due -to Awaloff and is described in German Pa-tent 599,~98 issued 3uly 3, 1934. In -the process evolved by Awaloff a pure distlllate without any minerals is produced. A con-tinuing flow of vodka, con-taining the usual ~0% alcohol, runs from a storage -tank to a potstill containing a liqui.d of about 4% by volume of alcohol. Distilla-tion -takes place in the potsti.11 and the spirit produced again has a ~0%
alcohol content. The flow from the storage -tan}c -to -the potsti.ll is carefully controlled to match the flow leaving the tailbox, aEter the cooler~ This ensures a s-teady strength o:E ~0~ alcohol by volume.
As indicated the process of Awalof:E produces a pure distillate having an alcohol con-tent of ~0% by volume.
The liquor is soft, that is there are no minerals present, because of the secondary distillation -the vodka has under-gone.
The presen-t invention seeks to produce a vodka in which the minerals occurring in the local wa-ter may be present. Alternatively the minerals that are -to be addecl may be at the discretion of -the distillery and may :re:Elect the particular flavour -that the distiller :Einds to be mos-t popular with consumers.
Accordingly, in a first aspec-t, the presen-t inven-tion is in a process for producing vodka by distilling a first aqueous solution oE alcohol having a relatively low alcohol content from a potstill, the volume of the first solution in the s-till being maintained by a flow of a second

Alternatively the minerals that are -to be addecl may be at the discretion of -the distillery and may :re:Elect the particular flavour -that the distiller :Einds to be mos-t popular with consumers.
Accordingly, in a first aspec-t, the presen-t inven-tion is in a process for producing vodka by distilling a first aqueous solution oE alcohol having a relatively low alcohol content from a potstill, the volume of the first solution in the s-till being maintained by a flow of a second
- 2 -aqueous solution of alcohol of relatively high alcohol content and condensing the vapour to produce vodka and is the improvement whereby (a) the first solution has an alco-hol content of abou-t 4.5% by volume and a minerals content, (b) -the second solution has an alcohol content of abou-t 41%
by volume and (c) the dis-tillate from the first solu-tion is eondensed and mixed with the undistilled first solution -to provide a vodka with an alcohol eontent of about 40% and a minerals eonten-t from the Eirst solutionO
In a fur-ther aspeet -the presen-t inven-tion is in an appara-tus Eor pxoducing a vodka con-taining the required about 40% by volume alcohol and containing minerals, the apparatus eomprising a still, a eondensor eommunica-ting wi-th the still and a eooler subsequent to the eondensor -to eon-trol the temperature of the vodka, and is -the improvement eomprising an intermediate -tank -to eommunieate (a) with -the eondensor and (b) with the supply of an aqueous solu-tion of aleohol of low aleohol eontent and with a mineral eonten-t whereby the distillate from the eondensor may be mixed with the aqueous solution o:E low aleohol eonten-t -to produce a vodka o:E the required alcohol content contalning minerals from the aqueous solution of aleohol of low aleohol conten-tO
PreEerably the apparatus ineludes a pipe extending from the still to the intermediate tank whereby the a solution of alcohol low in alcohol is the solution from -the still, prior to its distillation.
The invention is illustrated, merely by way of example, in the accompanying drawing which is a flow diagram of vodka production according to the present inven-tion:
The drawings show an apparatus that comprises a conventional potstill 2 having viewing openings 4, heating coils 6 fed by steam -through a line 8 having a valve 10.
There i5 a thermometer 12 to read -the -temperature oE the vapour. In the potstill there is distilled a firs-t aqueous solution 14 of alcohol. having a relatively low alcohol conten-t, according to the process of the present invention, about 4.5% by volume of alcohol. The vapour passes from the :L0 potstill along pipe 16 to a condensor 18. The cooling -fluid for the condensor is a second aqueous solution 20 of alcohol of relatively high alcohol content, about 41% by volume alcohol according to the present invention, which passes from -tank 22 through a pipe 24 having a valve 23 through -the condensor 18 to condense the vapours from the potstill 2.
The thus warm second solution 20 passes through pipe 26 in-to the potstill 2 where it is distilled. The condensate passes Erom the condensor 18 through pipe 28 to a precooler 30 cooled by a coolant, usually water, enteri.ng through pipe 32 and leaving through pipe 34. From the precooler 30 the condensate passes through pipe 36 to an intermediate -tank 38 fitted wi.th air supply openings 40 fed by air through pipe ~2 so the contents of the intermediate tank 38 may be stirred and mixed properly.
There is a supply of first aqueous solution 14 of alcohol to the intermedia-te tank 38 through pipe 44 from the potstill 2. The flow in the pipe 44 is -through a valve 46 and through a flow meter 48 as the intermedia-te tank 38 is essentially a proportioning tank in which a supply of -the condensate and a supply of the Eirst aqueous solution 14 of alcohol are mixed together to produce a vodka of the appropriate strength.
Air used as the mixing agent in the intermedia-te -tank 38 leaves the -tank through pipe 50 and bleeds through pipe 52 to a conven-tional aldehyde cooler 5~ Cool water enters the aldehyde 54 cooler through pipe 56 and leaves through pipe 58. It then passes through a final cooler 60, leaving through pipe 32 and passes to the precooler before leaving -the system -through pipe 34. The vod]ca leaves -the intermedia-te tank 38 through pipe 50 and passes -to pipe 62 and through the Einal cooler 60 to a conventional -tailbox (not shown) through pipe 66. The function of -the tailbox is conventional, that is to provide final control of the alco-]5 hol content of -the vod]ca.
In the process of the present invention the second solution 20 of alcohol is approximately 41% by volume alco hol made up of decarbonated, soft water and ethanol of approximately 96.6% purity. In the condensor 18, where it is used as coolant, this liquid is warmed -to a -temperature oE about 65 to 70 C. The condensate leaving the conclensor 18 has a temperature in the xange 70 -to 75 C. After -the intermediate tank 38 the condensate should have a tempera-ture oE about 60 C. As in conven-tional prac-tice -the ther-~5 mome-ter 12 reads the vapour temperature and, depending on the reading, the valve lO is controlled to regulate the flow of heating steam into the potstill. The steam leaves the potstill 2 through pipe 64.
the heating of the composite preform and the subsequen-t con-version to a container, achieve good contact wi-th, and secure enclosure between, the layers of material, -the functioning of the barrier layers is ensured.
It is also possible to apply a print and/or decora-tion to the outer surface of one o-f the inner part-preforms.
In that case, the design of the print and/or of the decoration is matched to the stretching of the material which occurs durlng the subsequen-t conversion of the preform to a container.
In a preferred embodiment of the invention, the material of the preform or part-preforms is stretched in the axial direction at a temperature within or preferably below the range of the glass transition temperature (TG) of the material. Preferably, the material is stretched by a mechan-ical procedure in which the preform is passed through one or more draw rings to reduce its wall thickness and thereby also its outer diameter. Canadian Patent Application No~ 378,503, filed May 28, 1981 in the name of K. M. Jakobsen et al, describes such a stretching procedure. Through the mechanical orientation, it is consequently easy to achieve an outer diameter of the inner part-preform which exactly matches the inner diameter of the outer part-preform, including the changes in dimension involved in coa-ting -the part-preforms with barrier layers.
The invention is described in more detail in rela-tion to a number of figures, in which.

In a fur-ther aspeet -the presen-t inven-tion is in an appara-tus Eor pxoducing a vodka con-taining the required about 40% by volume alcohol and containing minerals, the apparatus eomprising a still, a eondensor eommunica-ting wi-th the still and a eooler subsequent to the eondensor -to eon-trol the temperature of the vodka, and is -the improvement eomprising an intermediate -tank -to eommunieate (a) with -the eondensor and (b) with the supply of an aqueous solu-tion of aleohol of low aleohol eontent and with a mineral eonten-t whereby the distillate from the eondensor may be mixed with the aqueous solution o:E low aleohol eonten-t -to produce a vodka o:E the required alcohol content contalning minerals from the aqueous solution of aleohol of low aleohol conten-tO
