ABSTRACT:
Continuous freeze drying apparatus composed of a vessel whose internal chamber houses a cooled revolving cylinder on which a nebulizer sprays the material to be freeze dried.
A scraping blade, grazing the freezed material, removes it making it fall onto revolving holed planes heated by heating elements interposed between these revolving planes, in order to obtain a quick sublimation of the substance to be freeze dried.
