CIP in Freeze Drying The majority of CIP cycles used in freeze-dryers are performed with room temperature water. In some cases a higher temperature water (hot water) may be needed. Using a storage tank offers the opportunity to heat the water. Note: The hot water may cause proteins and biologics to stick to the freeze-dryer surfaces.

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 ...

The purpose of this study was to develop the correlation of cycle parameters between a laboratory and a production freeze-dryer. With the established correlation, key cycle parameters obtained using a laboratory dryer may be converted to those for a production dryer with minimal experimental efforts. In order to develop the correlation, it was ...
