Abstract

L'invention concerne un procédé de production de granulés d'acide céto-L-gulonique ayant une bonne faculté d'écoulement, ne formant pas de poussière, à partir d'acide céto-L-gluonique pur en fines particules. Selon ledit procédé, une solution d'acide céto-L-gulonique aqueuse ou contenant de l'eau est conduite à a) une installation de séchage par pulvérisation en lit fluidisé, b) une installation de séchage par pulvérisation à buse à un seul fluide ou c) une installation de séchage par pulvérisation à disque.
