ABSTRACT:
A freeze-dryer, especially for comestibles such as coffee extract, is connected to a condenser with a dust separator interposed therebetween. The discharge opening of the dust separator communicates with an after-drying device with its own discharge arrangement for the freeze-dried dust. The vapor produced in the freeze-dryer is introduced into a passage connecting the main dryer with the dust separator.
