Improvement in Apparatuses for Sterilizing Fermented Alcoholic
Liquors.
I, LORENZ ADALBERT ENZINGER, of Worms, in the Grand Duchy of Hessia, Engine-
manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to apparatuses for sterilizing formented alcoholic liquors, such
as beer, and its object is to carry out this process without loss of carbonic acid while
the liquors are being transferred from the store-vats to the casks or bottles in which
they are to be sold.
The apparatus forming the subject of my invention is composed of three divisions,
each consisting in a tank, a plurality of narrow tubes inserted with their ends in
two opposite walls of the tank (the said walls forming tube-plates), and in head-
plates or covers, screwed to the tube plates and having recesses whereby the superposed
tubes are connected together by pairs in such manner that the tubes of each vertical
row form a zig-zag conduit. Morcover, the conduits of the first division are connected
at their upper ends to the bottom of the conduits of the second division, while the
upper ends of the latter communicate with the bottom of the conduits of the third
division, so that a continuous passage is produced from the lowest tubes of the first
division to the uppermost tubes of the third division. The three divisions may be
placed one above the other or by the side of each other.
The lowest tubes of the first division are provided with means for connecting them
to the pipes leading to the store-vats, and the uppermost tubes of the third division
with like means for attaching thereto the pipes leading to the casks, &c. to be filled.
Besides this, the first or lowest tank is fitted with a pipe for introducing steam
thereinto, and the second tank with water induction and eduction pipes.
When the apparatus is to be put into operation, the tank of the first or lowest
division is filled with water, which is then heated by steam; the second tank is filled
with cold water, which is continuously renewed in the measure as heated water flows
off, and the tank of the third or uppermost division is filled with water and ice.
Subsequently the liquor to be treated is admitted under pressure into the tubular
conduits, and while rising therein, is first heated in view of its sterilization, thereupon
cooled by the water in the second tank, and finally reduced nearly to the freezing
point by the ice contained in the third or uppermost tank.
The carbonic acid set free during the heating process, is absorbed again by the
liquor upon its being cooled.

Improvement in Apparatuses for Sterilizing Fermented Alcoholic
Liquors.
I, LORENZ ADALBERT ENZINGER, of Worms, in the Grand Duchy of Hessia, Engine-
manufacturer, 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:-
My invention relates to apparatuses for sterilizing fermented alcoholic liquors, such
as beer and wine, and its object is to carry out this process without loss of carbonic

page_text: acid, alcohol or flavouring substances while the liquor is being transferred from tho
store-vats to the casks or bottles in which it is to be sold.
The apparatus which employ for this purpose is composed of three divisions, each
consisting in a tank traversed by tubes connected together to form one or more zig-
zag conduits, while the conduits of the different divisions are connected to each other,
so that a continuous passage is produced from the lowest tubes of the first division,
which are supplied with liquor from the store-vats, to the uppermost tubes of the
third division, whence the liquor is conducted to the casks, &c., to be filled. In the
first division the liquid is heated by means of water and steam in order to kill the
germs contained therein, in the second division it is cooled again to a certain degree
by water, and in the third division the cooling is finished by water and ice. The
three divisions may be placed one above the other or by the side of each other..
In the annexed drawing fig. 1 is a longitudinal section of an apparatus carried out
according to my invention and in which the three divisions are arranged in super-
position. Fig. 2 is a transverse section corresponding to fig. 1, while fig. 3 is an
end-view of an apparatus the divisions whereof are placed on the same level.
Referring to figs. 1 and 2, D1, D2 and D³ are the three divisions, each of which
consists in a tank a, two vertical rows of tubes b, inserted with their ends in two
opposite walls of the tank (the said walls forming tube-plates) and in the head-plates
or covers d, secured to the tube plates together with interposed india-rubber packings,
by means of clamping-screws e. (These screws are shown only in the lowest division,
fig. 1) The said head-plates or covers d have recesses, whereby the superposed
tubes are connected together by pairs in such manner that the tubes of each vertical
row form a zig-zag conduit. Preferably the head-plates d and the tubes are made
of tin, and the latter are soldered to the tube-plates. The conduits of the first
division, D¹, are connected at their upper end to the bottom of the conduits of tho
second division, D³, by the pipe S, while the upper ends of the division D' communicate
with the bottom of the conduits of the third division, D³, by the pipe, U. The liquid
to be treated is introduced at K and leaves the apparatus at L.
At the bottom of the tank of the division is arranged a perforated pipe Q
connected to the steam-pipe Q, while the tank of the division D is fitted with the
water-supply-pipe T and the overflow-pipe T'. The supply of water to the latter tank
may, however, take place in any other manner than through the pipe T.
When the apparatus is to be put into operation, the tank of division D₁ is filled
with water, which is thereupon heated by the steam introduced through pipe Q; the
tank of division D2 is filled with cold water, and the tank of division D3 with water
and ice. Subsequently the liquor to be treated is admitted under pressure at K, and
while rising in the tubular conduits, is first heated in view of its sterilization, there-
upon cooled by the water in the second tank, which is renewed in the measure as
heated water flows off, and finally it is reduced nearly to the freezing point by the ico
contained in the tank of the third division.
If beer is treated by means of the apparatus, the carbonic acid set free during the
heating process, and passing upward with the liquor, is absorbed again by the latter
upon its being cooled.
The apparatus shown by fig. 3, and in which the divisions D', D2, D3 are placed by
the side of each other and connected by inclined tubes, is adapted for treating wine
and other fermented liquors not containing carbonic acid, as any gaseous acid
collecting in the said tubes, would present an obstacle to the free passage of the
liquor.
The tanks a are preferably provided with wheels for facilitating their transport, and,
if they are to be placed one above the other, the tanks of the divisions D' and D' are
fitted with angle-iron shelves & for the wheels of the superposed tanks to stand on.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is:
In a sterilizing apparatus for fermented liquors, the combination of three tanks a

page_text: traversed by tubes b, head-plates d with recesses whereby communications are
established between the said tubes, connecting-tubes S and U, induction-pipe K,
eduction-pipe L, and overflow-pipe T', substantially as described.
