摘要：
Photographic emulsions are quickly chilled to a homogeneous, particulate gel by injection of carbon dioxide coolant, while the emulsion is agitated. This process is carried out in a housing having a pair of parallel auger screws to transport emulsion circuitously within the housing. Carbon dioxide coolant is injected through a plurality of nozzles in the housing and is then removed from the housing through a vent line.
