Summary:Process for the purification and reclaiming of a heterogeneous emulsion rich in fats, oils and proteins, consisting in filtering the emulsion on a rotary vacuum filter with a precoating including flour of organic filtering substance in which at least 80 % by weight of the constituents are between 50 and 300 micrometres in size and less than 10 % by weight are smaller than 50 micrometres in size, characterised in that the emulsion is brought into the filter trough beforehand at a temperature of between 60 and 70@ so that the temperature at the surface of the filter is between 50 and 55@. La présente invention concerne un procédé d'épuration et de valorisation d'une émulsion hétérogène riche en graisses, huiles et protéines, consistant à filtrer l'émulsion sur un filtre rotatif sous vide à pré-couche comprenant de la farine de matière filtrante organique dont au moins 80% en poids des constituants ont une taille entre 50 et 300 micro/mètre et moins de 10% en poids ont une taille inférieure à 50 micro/mètre, caractérisé en ce que l'émulsion est préalablement amenée dans le bac du filtre à une température comprise entre 60 et 70 degrés de façon que la température en surface du filtre soit comprise entre 50 et 55 degrés.
