Topic: AirFryer to dry filament and Pellets

Was talking to a plastics buddy about how great airfyers are for day old pizza and he wondered an airfryer would be a quick and good way to dry resin pellets?  Seems like it would work better than my 5gal bucket and light bulb.  Would an airfryer have too much air movement for pellets?  (I don't think I'd even try a powder). 

Of course, it would have to be dedicated to plastics.

I've tried some toaster ovens, and they like to well, toast things.  The one I tried seemed to be full on or off for the heating element as it tried to keep the fairly low temps that we need.

Any thoughts or experiences?

Thanks

The question is what is the lowest sustainable temp an airfryer can go down to? I use my freezer to dry and store filament. It works very well. Although not fast. It takes about a week to dry a known wet spool.

You use your freezer to dry?  Are we talking about a freeze dryer or an actual freezer?  Eg you just put it in there, no packaging around it, and that dries for you?

I mean my freezer, the same one I keep my ice cream in. It works through a process called sublimation.

It works, I was able to salvage a spool that had been sitting in the air for over a year and it worked great after coming out of the freezer for a week. So if time is not your enemy then a freezer works and it is something most of us already have.

I think 200F. I guess an issue would be getting some of the larger spools into the cooker.  I'd like to be able to do resin and filaments.

How do you not get condesnation when you bring the cold material out of the freezer?

You do, but filament is not like a sponge and just instantly absorbs moisture. The condensation doe evaporate before it get absorbed. I know it sounds counter productive but it has worked for me and it allowed me yo use a 1 year old spool I was ready to throw out.
