Estimating the term…
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.
A process for producing mill dried colloidal microcrystalline cellulose (MCC) comprising the steps of
Colloidal microcrystalline cellulose wherein said colloidal microcrystalline cellulose has a moisture content of less than 20% by weight, based on the total weight of the colloidal microcrystalline cellulose including moisture, and wherein said colloidal microcrystalline cellulose has a ratio (initial viscosity):(24 h viscosity), measured as 2 weight-% dispersion in water at 20° C. at a shear rate of 2.51 s-1, of at least 0.4.
