| Abstract |
In the process of ice-slurry making, ice adhesion on cooling wall or in narrow flow path disturbs continuous ice formation. In this study, the effect on the ice adhesion to cooling surface by some freezing experiments was investigated, quantitatively. Three types of solutions were frozen in various coating vessels with stirring. In the experiment, the ice adhesion between cooling wall and ice-slurry was evaluated by measuring stirring power. From the result, the stirring power of slurry mixture in PTFE-coating vessel was smaller than those in PE-coating, PFA-coating and bare SUS vessel. Especially, in EG 4/ PG 1.5/ HD 1.5 mass% solution, the stirring power in the PE-coating vessel was smaller than that in the PFA-coating or SUS vessel. |
