G135 Investigation on suppression of ice scraping force based on correlation between initial crystal orientation control of ice and structure of formed ice

Abstract

As one of typical formation methods of ice slurry, there is a harvest method where ice growing on a cooling solid surface is scraped by a scraper. This method has a merit that consideration of ice adhesion to the cooling solid surface is not required. However, it can be supposed that a scraping force of the formed ice depends on ice structure strongly. In this paper, the correlations among the controlled initial crystal orientation, initial freezing layer and ice structure were clarified, and then, apossibility of control of the scraping force was also clarified based on the correlations.
