Abstract

Apparecchiatura di liofilizzazione a flusso continuo costituita da un contenitore (10) nella cui camera interna (11) é alloggiato un cilindro girevole (22) raffreddato sul quale un nebulizzatore (30) spruzza del materiale da liofilizzare.Una lama raschiante (38), sfiorando il materiale congelato, lo rimuove facendolo cadere sui piani girevoli (46-48-50-52-54-56) forati riscaldati da elementi riscaldanti (68) interposti tra detti piani girevoli, onde ottenere una rapida sublimazione della sostanza da liofilizzare.
