Design of Freeze-Drying Processes for Pharmaceuticals

Design of Freeze-Drying Processes for Pharmaceuticals

Abstract. Design of freeze-drying processes is often approached with a “trial and error” experimental plan or, worse yet, the protocol used in the first laboratory run is adopted without further attempts at optimization. Consequently, commercial freeze-drying processes are often neither robust nor efficient.

The driving force of freeze drying process is the vapor pressure difference between the ice front and the surrounding environment. Vapor, water and ice coexist in equilibrium (triple point) at 0 0 C and 6.1mbar. Thus, at temperatures below 0 0 C and vapor pressure below 6.1 mbar, liquid is never present and sublimation of ice to water vapor ...

What Is a Freeze Dryer? - Millrock Technology Inc

What Is a Freeze Dryer? A freeze dryer removes water from a perishable material in order to preserve it, extending its shelf life and/or making it more convenient for transport. Freeze dryers work by freezing the material, then reducing the pressure and adding heat to allow the frozen water in the material to change directly to a vapor (sublimate).
