During freeze drying, the freezing step is considered the foundation to a repeatable and efficient process. A good freezing process can produce a consistent product and enable faster primary and secondary drying cycles.
Freezing without controlled nucleation results in different crystal structures and inconsistent pore sizes in the product, resulting in longer primary drying cycles.
To produce a consistent crystal structure and pore size a method of control is required that will nucleate all of the product in the freeze dryer at the same temperature at the same time and at the same rate.
FreezeBooster™ is a patent applied for technique to enable controlled nucleation during the freezing step of the freeze drying cycle.

FreezeBooster includes a control system and simple system modifications to enable controlled nucleation. Unlike other techniques, FreezeBooster does not need high positive pressures which require expensive ASME rated pressure rated vessels. FreezeBooster has been demonstrated to work on systems as simple as laboratory style systems with clear acrylic doors and never produces a positive pressure.
Combining FreezeBooster with Millrock’s Auto-Dry protocol optimization software can significantly reduce freeze drying times, resulting in a more efficient and repeatable freeze drying process.
