Distribution of Vapor Pressure in the Vacuum Freeze‐Drying Equipment [PDF]
Mathematical Problems in Engineering, 2012 In the big vacuum freeze‐drying equipment, the drying rate of materials is uneven at different positions. This phenomenon can be explained by the uneven distribution of vapor pressure in chamber during the freeze‐drying process. In this paper, a mathematical model is developed to describe the vapor flow in the passageways either between material plates

Researches on Vacuum Freeze-Drying
Bulletin of JSME, 1972 The rate of sublimation dehydration by the process of Vacuum freeze-drying was investigated after our former reports on the researches of sublimation of ice. Analyses of the temperature distribution in the sublimating materials by numerical methods and of the ideal drying-characteristics were presented. In the above analysis, the rate-determining steps
