Sublimation Freeze-Drying without Vacuum

Science, 1959
Analysis of the freeze-drying procedure shows that the passage of water vapor from the drying boundary through the dried shell is facilitated primarily by the vapor pressure gradient rather than by the absolute pressure of the system. This is experimentally confirmed, and a device for freeze-drying at atmospheric pressure is described.

Freeze‐drying using vacuum‐induced surface freezing

Journal of Pharmaceutical Sciences, 2002
A method of freezing during freeze-drying, which avoids undercooling of a solution and allows growth of large, dendritic ice crystals, was investigated. Aqueous solutions of mannitol, sucrose, or glycine were placed under a chamber vacuum of approximately 1 mbar at a shelf temperature of +10 degrees C.

Rapid vacuum freeze‐drying of meat

Journal of the Science of Food and Agriculture, 1958
AbstractFreeze‐drying carried out in conventional equipment is a slow process, the rate of drying being limited by the rate of transfer of heat of sublimation. A method is described to carry out rapid freeze‐drying of meat or other foodstuffs by laying the pieces between heater plates fitted with metal spikes which conduct heat uniformly and ...

Modeling of Vacuum Desorption in Freeze-Drying Process

Drying Technology, 2005
Abstract A mathematical model of multicomponent vacuum desorption, which occurs in vacuum freeze-drying process, was developed. In freeze-drying porous biomaterials and pharmaceuticals are considered and the vacuum freeze-drying process, especially the moisture desorption in its final stage, is investigated.
