Document Type and Number:

WIPO Patent Application WO/2010/005015

Kind Code:

A1

Abstract:

Provided is a freeze-drying device that can improve processing capacity while avoiding variability in grain size. A freeze-drying device (100) pertaining to an embodiment of the invention is equipped with a freezing bath (10) constituting a vacuum chamber and an injector (25). The injector (25) has a pipe member (29) provided inside the vacuum chamber and a nozzle (9) with multiple injection holes (92) that faces the inner side of the pipe member (29). The injector (25) injects a raw material fluid (F), that is supplied to the pipe member (29), into the vacuum chamber through the nozzle (9). Because the respective injection holes (92) are formed so as to face the inner side of the pipe member (29), the raw material fluid (F) is injected through the respective injection holes (92) at the same injection pressure. As a result, the processing capacity can be improved while avoiding variability in grain size.
