Product resistance
WebbA product temperature variability of approximately ±4.4 °C was defined for a product dried layer thickness of 5 mm. The present approach can be used to estimate the risk of failure of the process due to mass transfer variability when designing freeze-drying cycle. Webb1 apr. 2011 · Once again, it has been shown that the apparent product resistance of the dry layer is maintained or even reduced if the newly freeze-dried material is maintained in the microcollapsed state. In fact, the path taken by water molecules during primary drying in the microcollapsed state appears to be less tortuous and does not present a significant …

Webb17 sep. 2010 · The pore diffusion model is used to express the dry layer mass transfer resistance, , as a function of the ratio r e /τ, where r e is the effective pore radius and τ is the tortuosity factor of the dry layer. Using this model, the effective pore radius of the dry layer can be estimated from the sublimation rate and product temperature profiles measured …
