| description | The invention relates to a method for drying microfibrillated cellulose, comprising at least the following steps: (i) applying a composition comprising microfibrillated cellulose and a liquid onto a cold surface; (H) removing the frozen composition formed in step (i) from said surface to form frozen particles; (iii) optionally increasing the size of the frozen particles formed in step (ii); (iv) drying the frozen particles formed in step (iii) comprising: subjecting said particles to a cold moving gas thus removing liquid by means comprising sublimation and optionally (v) isolating the microfibrillated cellulose formed in step (iv). The invention also relates to a device for carrying out the method of the invention.
L'invention concerne un procédé de séchage de cellulose microfibrillée, comprenant au moins les étapes suivantes : (i) application d'une composition comprenant de la cellulose microfibrillée et d'un liquide sur une surface froide ; (H) élimination de la composition congelée formée à l'étape (i) de ladite surface pour former des particules congelées ; (iii) augmentation éventuelle la taille des particules formées à l'étape (ii); (iv) sécher les particules congelées formées à l'étape (iii) par soumission des particules à un gaz de déplacement froid, ce qui permet d'éliminer un liquide par sublimation et éventuellement (v) isolation de la cellulose microfibrillée formée à l'étape (iv). L'invention concerne également un dispositif permettant de mettre en uvre ledit procédé. |
