Title:

FREEZING TEMPERATURE CONTROLLABLE SPRAY FREEZING TOWER FOR PREPARING MICRON-SIZED SPHERICAL ICE PARTICALS

Document Type and Number:

WIPO Patent Application WO/2017/152594

Kind Code:

A1

Abstract:

A freezing temperature controllable spray freezing tower for preparing micron-sized spherical ice particles, comprising: a tower body (10), an atomization system (20), a feeding system (30), an air circulation supply system (40), a refrigeration system (50), and a tower wall cooling and heat-insulation system (60). An air reserving cavity (11) is provided on the top of the tower body (10), a freezing chamber (12) is provided inside the tower body (10), and a material collection chamber (13) is provided on the bottom of the tower body (10), the air reserve cavity (11), the freezing chamber (12), and the material collection chamber (13) being in communication with one another. The atomization system (20) is in communication with the air reserving cavity (11), the feeding system (30) is in communication with the atomization system (20) by means of a feeding pipe (36), and the circulating air supply system (40) is in communication with the bottom of the freezing chamber (12) and with the refrigeration system (50) by means of a circulating air return pipe (47) and an air pipe (48), respectively. The refrigeration system (50) is connected to the air reserving cavity (11) and the tower wall of the tower body (10). The tower wall cooling and heat-preserving system (60) is wrapped around the tower wall.
