Hi there, I currently am testing woodwind reeds with compressed air to check stability and a few other parameters to make sure they are fit for production.

These reeds are for a bagpipe-like instrument, and they are very sensitive to moisture, so I need to be sure that the air is dry.

At the moment the setup consists of a compressor, which is hooked up to some pressure valves, which then blows upon the reeds, and I have a piezoelectric sensor to measure the pitch produced.

Moisture will cause the reed to degrade, so I think I need to find some way to pass the air through a desiccant- but I can't think of a way that will maintain pressure, or risk spraying small amounts of desiccant on the reed.

Does anyone know of any way that I could possibly achieve this?
