摘要： A mill dried colloidal microcrystalline cellulose (MCC) is obtained in a process comprising the steps of a) providing colloidal MCC having a moisture content of from 20 to 75 percent, based on the total weight of the moist colloidal MCC; and b) mill-drying the moist colloidal MCC in a single device capable of milling and drying in combination. The process can provide mill-dried colloidal microcrystalline cellulose having similar particle size distribution (LEFI, DIFI and EQPC), and a similar or higher tapped/untapped bulk density, a similar or lower Carr index, a similar or higher viscosity and a similar moisture content as the corresponding spray-dried colloidal microcrystalline cellulose.

The process can provide mill-dried microcrystalline cellulose having a higher tapped/untapped bulk density and/or a lower Carr index, while keeping a similar moisture content, as the corresponding spray-dried microcrystalline cellulose.
