Hello all. ...
Hello, bigpoppadoc -- welcome to TSP Forum!
Don't worry, we aren't the sorts to go banning new members just because of minor mistakes.
We like to toy with our food first
I mean, this is a pretty friendly place.
Looking forward to hearing about your freeze-drying experiences.
Stop by the Intro Thread
when you've got a few minutes and say hi.
Two weeks does seem to be a lot longer than I ever imagined it would take. That is how long they take commercially too? Or did?
The only time I've ever used one of these machines was in a biochemistry lab, but yeah. Slow steady evaporation (or sublimation
, technically) of water vapor directly from the frozen material -- it takes a long time, assuming you want the material to stay ice-cold during the process.
