Abstract
Freeze-dried products of high quality produced from materials to be freeze-dried in a freeze-drying apparatus comprising a sealed vessel enclosing a processing chamber provided therein with a rotary cage receiving a gas-permeable container containing one or more frozen products of the said material, prepared by freezing the said material with dry ice, and a heating device for heating the frozen product by radiant heat rays, wherein the freeze-dried product is produced by a process which can attain efficient sublimating removal of large amount of carbon dioxide gas evolved from dry ice and of moisture included in the material, while preventing adhesion of the frozen products to each other and while permitting reduction of the sublimation duration, wherein the frozen product retained in the gas-permeable container placed in the rotary cage is heated uniformly by the heating device under vacuum condition while holding it under rotational movement to thereby facilitate the sublimation of dry ice and of the frozen moisture from the frozen product.
