Summary

This study was conducted to clarify continuous production of ice slurry by utilizing constitutional supercooling promoted by mixing of two aqueous solutions whose solute concentrations are different. In this technique, fine ice crystals are made under volume-catalyzed nucleation without heat transfer surface. In the experiments, cooled sucrose solution and water were mixed in the cylindrical vessel, and ultrasonic vibration was applied to promote nucleation in the supercooled solution. It was found that the ice making process is classified into three characteristic patterns: stable ice making, ice making in stratified concentration layer due to defect in solute-mixing, and no ice making due to no supercooling by mixing. The characteristics of ice making were discussed with the mixing ratio and total flow rate of solutions.
