19.7k Location:Ontario, Canada Posted March 8, 2006 Freeze drying works by quickly freezing the item (and that could include flowers or dead animals as this technology is used to preserve wedding bouquets and in taxidermy) to a very low temperature, then placing it under vacuum to remove the air and water vapour.
