FREEZE-DRYING DEVICE AND FREEZE-DRYING METHOD

WIPO Patent Application WO/2010/005021

A1

Provided are a vacuum freeze-drying device and a vacuum freeze-drying method that can improve frozen particle drying efficiency. The freeze-drying device (100) is equipped with a freezing bath (10) into which a raw material fluid (F) is injected. A rack (16) vibrates in a horizontal direction as a vibration generator (31) is actuated during the injection, after the injection, or during the period immediately before and after the injection of the raw material fluid (F). As a result, frozen particles deposited on the rack (16) are dispersed evenly over the rack (16) in such a manner as to reduce the thickness of the deposition, or to form a single layer. Thus, the freezing efficiency and drying efficiency of each single particle can be improved.
