This paper deals with the continuous production mechanism of slush ice by use of a vertical oscillating cooled wall immersed in ethylene glycol solution. The cooled wall was operated with cyclic horizontally oscillation motion in the test vessel. Experiments were carried out under a variety of conditions, such as both of the acceleration and stroke of the cooled wall, and initial concentration of solution. it was found that ice layer formed on the cooled wall continuously separated from its surface and fine ice crystal became to spread in the test vessel, which reveals the possibility for production of slush ice by the present method. Furthermore, an analysis was performed to determine the separation conditions of ice layer caused by the wall motion. The continuous production range of slush ice was well predicted by the present analysis.
