Abstract
The subject invention provides a freeze dryer apparatus having an interim condensing system, preferably a refrigeratable condensing surface. The interim condensing system condenses vapors within the product chamber of the freeze dryer apparatus when the main condenser coil, which normally condenses vapors within the product chamber, needs to be defrosted. The refrigeratable condensing surface is preferably mounted inside the product chamber.
