Abstract: The present invention relates a process and a system for the point-of-use dilution of microfibrillated cellulose (MFC) from a higher solids content to a lower solids content, for example from a solids content in the range of 5% weight by weight (“w/w”)-50% w/w, preferably 5% w/w-30% w/w, further preferably 5% w/w-15% w/w, down to a solids content of below 7% w/w, preferably below 5% w/w, preferably to a solids content of 0.01% w/w-5% w/w, further preferably to a solids content of 0.1% w/w-3% w/w.

Abstract: The present invention relates to a process for the spraying of microfibrillated cellulose (MFC), which has a comparatively high solids content, onto a surface, thus forming a stable and homogeneous film coating of MFC on said surface. Therein, the MFC of the comparatively high solids content is subjected to a pressure drop in a nozzle, which pressure drop exerts shear pressure onto the MFC, thus lowering the viscosity during the spraying and coating process.

Abstract: 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.
