Title (EN) CRYSTALLISATION PROCESS USING ULTRASOUND
(FR) PROCESSUS DE CRISTALLISATION FAISANT APPEL AUX ULTRASONS
Abstract: front page image
(EN) The present invention relates to a process for the crystallisation of a solid phase from a liquid, characterised in that the liquid during crystallisation is subjected to ultrasound in the absence of transient cavitation. In particular the liquid is sonicated under such conditions of time and frequency that nucleation of stable crystals in the liquid is induced without exceeding the cavitation threshold and the occurrence of transient cavitation and the accompagnying flavour deterioration is avoided. The liquid preferably is a triglyceride oil such as a vegetable oil or animal fat, e.g. liquefied milk fat.
(FR) La présente invention concerne un procédé permettant la cristallisation d'une phase solide à partir d'un liquide, caractérisé en ce que le liquide, au cours de la cristallisation, est soumis à des ultrasons sans que se produise de cavitation transitoire. En particulier, le liquide est soumis aux ultrasons dans de telles conditions de temps et de fréquence que la nucléation de cristaux stables dans le liquide est induite sans que soit dépassé le seuil de cavitation et de façon que l'on évite l'apparition d'une cavitation transitoire et la détérioration de goût qui l'accompagne. Le liquide précité est, de préférence, une huile triglycéride telle qu'une huile végétale ou une graisse animale, par exemple des matières grasses du lait liquéfiées.
