ABSTRACT:
A freeze dryer for the freeze drying of, for example, comestible products such as fruit juices and coffee, comprises a sublimation chamber having a heating plate upon which the products are disposed and an ice condenser spaced from the heating plate and upon which the moisture driven out of the product sublimes in the form of ice. According to the invention between the heating place and the ice condenser a heat pump is disposed so that the heat transferred to the ice condenser is returned via the heat pump to the heating plate.
