    2019-12-11 · Flowability is a factor for several processes in the pharmaceutical industry. These include powder transfer through comparatively large equipment such as providing con-sistent flow out of a blender, bin, drum hopper, Y-branch/chute, press hopper, or dust collector powder storage,which could for example result in caking tendencies within a vial,

    2020-7-1 · As drying progressed, the drying rate tended to decrease, presenting as a falling rate period. The decrease of drying rate resulted from the reduction in absorption of microwave energy due to the decreasing dielectric loss factor caused by the reduction of free water content in dried GBR (Zarein et al., 2015, Zhang et al., 2006).

  • Drying Rate - an overview

    During the falling drying rate period, the drying rate N is no longer constant. Equations for drying time during this period can be developed depending on the relationship between N and X and the properties of the solid. Kinetic models for predicting the drying rate curve, including during the falling rate period when internal heat and mass transfer mechanisms are limiting, are described ...
