This paper deals with the use of a small-scale freeze-dryer where few vials are loaded, e.g. 19, ...each 10 mL, or 7, each 20 mL. The system has a metallic ring surrounding the batch of vials, in contact with the external ones: its temperature is manipulated independently from that of the shelf.
Vacuum freeze-drying (VFD) can be used for preserving food with small effects on nutritional qual...ities. VFD modelling is useful to select off-line the best operating conditions to avoid product overheating and reduce the drying time, thus saving energy.
