Drytote test

A project log for Solar filament drier

How to keep filament dry while being too poor to afford electricity.

After a bag with drytote yielded wet filament, the decision was made to test drytote in the solar drier with the circulation fan & no filament.

Over several weeks, it didn't do anything despite the indicator being blue.  The leading theory is the silica gel has to be cold to absorb water while filament has to be hot to release water.  The solar drier is just going to release the water from the silica gel & the filament every day without anyone doing a net absorption.  You need a desiccant which absorbs at high temperature.

The blue dot stayed blue up to 40%, which is where filament degrades.
