Summary

In a dynamic ice storage system, one of typical methods to form ice slurry is a "Harvest method" where ice growing on the cooling surface is scraped by a rotary knife. This method has an advantage that ice adhesion to a cooling wall, which is a serious problem in a conventional method, is not necessary to be considered. In this study, ice was formed on a carbon steel surface by cooling an ethylene-glycol solution with stirring, and ice growing on the cooling surface was scraped. At that time, scraping force was measured, varying supercooling degrees of the solution, ice formation times, concentrations of the solution and surface temperatures and surface roughness of the carbon steel. And, influences of the above parameters on scraping force were clarified, and behaviours of ice scraped from the carbon steel surface were classified. Moreover, ice growing on the surface was continuously scraped repeatedly. At that time, influence of the number of scrapings on scraping force was clarified.
