DEVICE FOR PRODUCING DRY POWDER USING SPRAY FREEZE GRANULATION AND SYSTEM FOR PRODUCING DRY POWDER USING SPRAY FREEZE GRANULATION

Document Type and Number:

WIPO Patent Application WO/2019/175954

Kind Code:

A1

Abstract:

[Problem] To provide a device for producing a dry powder using spray freeze granulation and a system for producing a dry powder using spray freeze granulation, wherein manual steps are minimized and mass production of a dry powder through continuous operation and long-term operation is possible. [Solution] Provided is a device for producing a dry powder using spray freeze granulation, the device being provided with: a spray mechanism part which has a freezing preventing means and sprays a raw liquid into a freeze granulation chamber; and a freeze drying part which is configured to be detachable from a lower part of the freeze granulation chamber, has a storage container for storing frozen granulated bodies generated inside the freeze granulation chamber, and freezes and dries the frozen granulated bodies stored inside the storage container, wherein the freeze granulation chamber is cooled by any one or a combination of direct cooling, in which cooling is performed by introducing a coolant directly into the chamber, and indirect cooling, in which cooling is performed by filling a coolant into a jacket structure provided around the freeze granulation chamber. Also, provided is a system for producing a dry powder using spray freeze granulation, wherein the system, in addition to the device for producing a dry powder, is also provided with a collection means for collecting moving frozen granulated bodies according to the discharge of the coolant.
