抄録

The production characteristics of ice particles treated with surfactant additives and brines in the case of using vacuum ice production system have been investigated. In the present study, cetyl dimethyl betaine was used as surfactants and the results were compared with those in the case when poly(oxyethylene) sorbitan monooleate used in the previous studies was tested. From the results, it was found that ice particles size produced by using a vacuum system becomes much smaller than that made by the scraper ice production system used in the previous study. It was also found that the size of ice particles treated with the present surfactants without brine still remains small. Additionally, the fluidity of ice slurry treated with the present surfactants was enough high though the drag reduction could not be observed due to the small diameter of the present test pipe. From these results, a combination of the present surfactant treatment without brine and the vacuum ice production system was concluded to have an advantage for the production of fine ice particles.
