Microwave freeze-drying of aqueous solutions
The freeze-drying process has been plagued with problems, such as long drying times and inefficiency. Microwave freeze-drying has proven its potential as way of reducing long drying times associated with freeze-drying, and as a result, there has been a considerable amount of work done to increase …

Use of Volumetric Heating to Improve Heat Transfer During Vial Freeze-Drying
Freeze-drying (lyophilization) is a drying process which is used to remove water from heat sensitive products, usually for the purpose of preservation. By removing water, the product becomes more stable at room temperature. This is a common process in the pharmaceutical industry because …

The development of micro-sample electrical impedance analysis for freeze-drying process development
Background: Since primary drying in freeze drying cycle is the longest step, it is desired to use optimal process conditions for efficient drying by running a process under the critical temperatures (e.g., Tg’, Teu, Tc’). Multiple techniques and instruments (e.g., differential scanning calorimetry, …

Coupled fluid-thermal analysis of low-pressure sublimation and condensation with application to freeze-drying
<p>Freeze-drying is a low-pressure, low-temperature condensation pumping process widely used in the manufacture of bio-pharmaceuticals for removal of solvents by sublimation. The goal of the process is to provide a stable dosage form by removing the solvent in such a way that the sensitive …
