Richard,

The food industry typically used a more standard refrigerated air dryer to remove moisture from compressed plant air. Due to the excessive heat generated by most air compressors, there is a lot of condensate generated that must be removed.

A dessicant dryer is a simpler device using a replaceable media (dessicant). Most have controls for a regeneration cycle to offload condensate. The media material (beads) may have to be replaced if you re-commission the system.

Either way, yes, the device "drys" the air. This is most important when using air for sensative instrumentation, or for that matter, painting your classic SeaCraft, where water in an expensive 2 part paint would have destructive results.

Here's an example from Hankinson .

How's that for "off topic"? At least I tied it into SeaCraft.
