Economic Analysis of a Freeze-Drying Cycle - MDPI

Economic Analysis of a Freeze-Drying Cycle - MDPI

As shown in Table 1, the OC per cycle performed in the industrial freeze-dryer increased by a factor 30 with respect to the pilot-scale freeze-drier, while the CC increased by a factor 20. This difference is quite normal considering that the price of the machine usually grows less than linearly with the dimension of the machine itself.

A Guide To Freeze Drying for the Laboratory

Prefreezing: Since freeze drying is a change in state from the solid phase to the gaseous phase, material to be freeze dried must first be adequately prefrozen. The method of prefreezing and the final temperature of the frozen product can affect the ability to successfully freeze dry the material. Rapid cooling results in small ice crystals ...
