I have read that freeze drying is the best way to salvage wet books (http://www.ccaha.org/uploads/media_items/technical-bulletin-salvaging-books.original.pdf). However, freeze dryers run in the thousands of dollars, and I don't know anyone who has one I can borrow. Solution: make my own! I have found some instructions on creating a vacuum system (http://www.tk560.com/phpBB2/viewtopic.php?t=424), and I assume adding dry ice will create the desired temperatures. However, I can't seem to figure out the what qualifies as a vacuum chamber. (I was a physics minor in college, but I don't have an engineering background.) The examples cite water heaters, etc., but to my knowledge, the examples cited cannot be opened to place books inside. Could I attach the vacuum system to a cooler/ice chest, or would it implode under the pressure or leak? Could I simply place dry ice in or around the cooler to achieve the desired temperature?
