Freeze drying question
Let's say you have some fruit that you'd like to freeze dry and you don't have a freeze dryer. Could you freeze the fruit and then quickly take them
out of the freezer and placed them in a vacuum chamber and reduce pressure?
Poor man's freeze drying if you will.

Freeze drying takes a while.
Many hours, maybe a day or two.
Gotta keep it frozen while it dries.
You might be able to dry the stuff in lyophilization flasks inside a freezer if you drill a hole in the freezer for a vacuum line.
Freeze drying takes a pretty good vacuum as you're actually sublimating the ice.

I thought the "freeze" part happened by itself? Like, due to the water boiling off in the vacuum. Does that not happen?

You freeze them, then you apply vacuum to them for the water to sublime away.
