This report describes the particle distribution characteristics of an ice slurry treated with surfactants and brines generated by a vacuum production system. Ice particle size in slurries with surfactants was measured by an image-processing method at different concentrations of surfactant and brine. The results indicate that the effect of the ice fraction is very small on ice particle size obtained by the present vacuum production system. It was also found that the influence of brine concentration on particle size was very small. The effect of surfactant concentration on particle distributions was also very small. In addition, a small amount of surfactant reduced ice particle size compared to those of brine systems without surfactants. It is concluded that no brine system is economical for ice slurry generation by a vacuum production system.
