Two components are common to all types of freeze-dryers: a vacuum pump to reduce the ambient gas pressure in a vessel containing the substance to be dried and a condenser to remove the moisture by condensation on a surface cooled to -40 to -80 C (-40 to -112 F). The manifold, rotary and tray type freeze-dryers differ in the method by which the dried substance is interfaced with a condenser. In manifold freeze-dryers a short usually circular tube is used to connect multiple containers with the dried product to a condenser. The rotary and tray freeze-dryers have a single large reservoir for the dried substance.</div> Sat, 21 Apr 2012 03:24:31 GMT BourassaNowell494 https://pm.haifa.ac.il/index.php?title=User_talk:BourassaNowell494 https://pm.haifa.ac.il/index.php?title=BourassaNowell494 <p>BourassaNowell494:&#32;Created page with 'There are essentially three categories of freeze-dryers: the manifold [http://www.china-drying-equipment.com drying equipment], the rotary freeze-dryer and the tray style freeze-…'</p> <hr /> <div>There are essentially three categories of freeze-dryers: the manifold [http://www.china-drying-equipment.com drying equipment], the rotary freeze-dryer and the tray style freeze-dryer.
