Evaluation of spin freezing versus conventional freezing as part of a continuous pharmaceutical freeze-drying concept for unit doses
09 Jun 2023 | Contributor(s):: De Meyer, L., Van Bockstal, P. -J., Corver, J., Vervaet, C., Remon, J. P., De Beer, T.
Spin-freezing as alternative freezing approach was evaluated as part of an innovative continuous pharmaceutical freeze-drying concept for unit doses. The aim of this paper was to compare the sublimation rate of spin-frozen vials versus traditionally frozen vials in a batch freeze-dryer, and its...

A primary drying model-based comparison of conventional batch freeze-drying to continuous spin-freeze-drying for unit doses
09 Jun 2023 | Contributor(s):: Leys, L., Vanbillemont, B., Van Bockstal, P. J., Lammens, J., Nuytten, G., Corver, J., Vervaet, C., De Beer, T.
An innovative continuous spin-freeze-drying technology for unit doses was recently developed. For this technology, a mechanistic primary drying model was developed allowing the calculation of the optimal dynamic drying trajectory for spin-frozen formulations. In this work, a model-based and...
