Abstract

L'invention concerne les industries de la fermentation. Elle a pour objet un procédé pour mettre un gaz et un liquide en contact dans un système clos comprenant une conduite ascendante 2 et une conduite descendante 1 en communication mutuelle et avec un compartiment 3 surmontant leurs extrémités supérieures, suivant lequel, de façon continue, on fait circuler un liquide, on soutire un liquide, on injecte un gaz dans le liquide et on dégage un gaz du liquide et, après passage dans le compartiment, on soutire ce gaz du système, la pression gazeuse au-dessus du liquide dans le compartiment étant de 3 à 10 bars au manomètre. Ce procédé est préféré pour conduire économiquement une fermentation produisant de la protéine d'unicellulaires.The invention relates to the fermentation industries. It relates to a method for bringing a gas and a liquid into contact in a closed system comprising an ascending pipe 2 and a descending pipe 1 in mutual communication and with a compartment 3 surmounting their upper ends, according to which, continuously, one circulates a liquid, a liquid is withdrawn, a gas is injected into the liquid and a gas is released from the liquid and, after passing through the compartment, this gas is withdrawn from the system, the gas pressure above the liquid in the compartment being 3 to 10 bars at the pressure gauge. This method is preferred for economically driving a fermentation producing unicellular protein.
