Powder Desolventizing
Powder Desolventizing
(OP)
May someone direct me to any kind of technical information (handbook or website) that I can learn from about process basis and practical techniques of solvent vaporizing (methylene chloride) from very small solid grain powder?
Any help would be appreciated.
Thanks in advance.

RE: Powder Desolventizing
You could also do something called fluidizing. You fill a tube with some powder and gently blow something like warm, dry nitrogen through the powder from the bottom so that the powder is gently blown up (but not out) inside the tube. This is easier and doesn't take too long, but can leave traces of solvent that the vacuum might not.
For a volatile solvent like this, just heating the powder will drive off quite a bit of solvent.
