416 Investigation on correlation between ice scraping force and ice structure formed by control of initial ice crystal orientation

Abstract

Since the Great East Japan Earthquake occurred in 2011, power load leveling has become a major and urgent issue in Japan. Thus, in order to promote the issue, use of ice slurry formed during the midnight for a cold storage of foods at a daytime attracts attention. A harvest method where ice growing on a cooling solid surface is scraped by a scraper is a typical formation method of ice slurry. However, ice structure strongly affects the scraping force. So, to control ice structure, the correlation among the controlled initial crystal orientation and ice structure has been investigated. In this paper, based on the correlation and removal behavior of ice, a possibility of control of the scraping force is investigated.
