For an automated loading and unloading solution of a freeze dryer a slot door in the clean room area is required.
The loading and unloading of the freeze dryer is done with a constant loading level to allow direct connection to a filling line. The optimal, well designed Christ-solution is a very compact construction, which is easy to be cleaned as well. This offers advantages specifically for isolator solutions and automated push-pull systems.
Typically the freeze dryer is equipped with a slot door in the clean room and a swing door in the machining area, also door-in-door solutions are possible.
With a slot door the freeze dryer could be easily connected with an isolator or an glove box.
