<p>An impregnator is used to admix a liquid (F) which has a low gas content, if any, with gas (G), especially for admixing a non-frothing or weakly frothing or CO<sub>2</sub>-containing beer precursor with CO<sub>2</sub>, comprising a mixing cell (1), especially a tubular mixing cell (1), which, apart from a liquid feed (6) which opens into it, a gas feed (3) which opens into it and an outlet (7), is sealed off from the environment, at least one impregnation body (11, 13, 15; 213; 513) being arranged in the mixing cell (1) such that the passage of liquid (F) and of the gas (G) through the mixing cell (1) must inevitably pass through the impregnation bodies (11, 13, 15). In the impregnator, at least one impregnation body (11, 13, 15) which is composed of a porous solid, specifically of a foam, a sponge, a hollow fiber module or a sintered material, is arranged in the mixing cell (1).</p> |
