Abstract

L'invention décrit un procédé et un appareil de clarification de liquide par floculation. Dans un liquide trouble, pouvant former une mousse avec du gaz injecté et qui contient de la matière pouvant former avec ce gaz un floc capable de flotter, on injecte un gaz compatible, afin de former de la mousse au sommet du liquide et les constituants d'un floc dans sa masse. On laisse ensuite le liquide ainsi traité séjourner tranquillement pour que les constituants du floc forment un floc qui peut flotter et monter à la surface du liquide. Le liquide clarifie se rassemble sous le floc. Dans une région contenant la mousse, on peut prélever du gaz à injecter dans le liquide, afin de récuperer le liquide de la mousse et d'empêcher une perte de liquide sous forme de mousse. Application : clarification de jus de fruits, notamment du jus de raisin.
