Abstract

L'invention concerne un mélange en purée préparé par broyage à partir d'ensembles de cellules végétales ou animales, notamment à partir de fruits entiers, et par désintégration sous forme de magma. Ce magma est cédé à une installation de filtration comprenant au moins une section d'écoulement (Passe) (9, 9', 10, 10', 11, 11', 12, 12') destinée au flux et une sortie (30) destinée aux fractions liquides séparées (perméat). A cette occasion, le mélange à séparer est recyclé plusieurs fois sous pression par les sections d'écoulement en formant ainsi un circuit, les fractions liquides étant séparées sous forme de jus. On renonce à la technique connue de pressage du jus et le magma est directement filtré.
