Apparatus for purifying carbon dioxide vapors of fermenting liquids

In combination with a container of fermenting liquids, notably in a vinificator, a recuperation and carbonic-gas purifying apparatus comprising:

• a condenser, connected to said container to receive carbonic gas to be purified by the removal of vapors contained therein, for condensing said vapors;
• a refrigerating unit connected to said condenser, and
• means for extracting purified carbonic gas from the condenser;
• means for returning the liquid condensate of said vapors from the condenser to the container,
• said condenser comprising a body fixed on and connected to an upper part of the container by a delivery member, said body having an inner part, a series of reflux tubes through which the carbonic gas passes and in which said vapors reflux, said reflux tubes being housed in the inner part of the body and including a plurality of hemispherical baffles vertically spaced on a pair of carrying bars each of said baffles being provided with an orifice, said orifice of adjacent baffles being laterally offset from one another to provide a tortuous path for said vapours within said reflux tubes, and means for circulating a refrigerating fluid from said refrigerating unit to said inner part of the condenser body, said condensate returning means including in a lower part of said body, under said reflux tubes, a funnel having a delivery tube which in use extends into the fermenting liquid in said container, and said extracting means further including an exhaust pipe connected to an upper part of said body to evacuate the purified carbonic gas.
