Abstract
A freezing temperature controllable spray freezing tower for preparing micron-sized spherical ice particles includes a tower body, an atomization system, a material feeding system, a circulatory air supplying system, a refrigeration system and a tower wall cooling and thermal insulation system. An air storage cavity is formed at a top of the tower body, a freezing chamber is formed inside the tower body, a material collecting chamber is formed at a bottom of the tower body. The atomization system is in communication with the air storage cavity, the material feeding system is in communication with the atomization system, the circulatory air supplying system is in communication with the bottom of the freezing chamber and the refrigeration system respectively, the refrigeration system is connected to the air storage cavity and a tower wall of the tower body. Thus the operation is convenient and simple.
