I Googled and got this.
"Regenerating CaCl2: Even in a vacuum desiccator, calcium chloride will eventually become hydrated with use and will lose much of its drying power. The hydrated CaCl2 can be collected, put in a borosilicate glass beaker, and heated in an oven at or above 200°C (392°F) for a few hours."
Dry CaCl2 is deliquescent and quickly so.
