Drying Rate an overview ScienceDirect Topics

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

The effect of crushing on the drying of pasture plants.

Crushing leguminous pasture plants greatly reduced the time required for drying, particularly for succulent stems. The time taken to dry clover to 30 per cent. moisture was reduced from 60 to 40 hr. with light crushing and to 29 hr. with heavy crushing, and for lucerne from 101 to 50 and 26 hr., respectively. In a mixed clover and ryegrass sward the advantages were not so marked and the

Pharmaceutical Issues when Crushing, Opening or Splitting

Crushing an oral solid dosage form may have a negative impact on the stability of the drug substance. If an enteric coating, which protects a drug from the acidic environment in the stomach, is removed by crushing the tablet, the in vivo drug degradation will increase, with less drug available to produce the desired clinical effect.
