In the secondary or ultimate drying stage, the residual dampness information is lessened just as much as feasible to make certain that the merchandise is in the permanently storable point out. The h2o certain by adsorption at The interior surface area in the merchandise must be eliminated. To attain this, it is often important to defeat h2o’s capillary forces.
As an example, lots of lyophilized drug products expertise an increase in thermal security and no more need frozen storage. This delivers a more inexpensive, reduce hazard, and successful way to optimize storage and distribution.
