Abstract

Seawater ice slurry can be produced with cooling process in evaporator by utilizing salt content in the seawater as freezing point depressing additive. Ice slurry technology can play an important role in the process of storing fish in the open sea because the quality of the fish that cooled with ice slurry is much better than ice cubes. Evaporator with polytetrafluoroethylene (PTFE) coating blade and a certain clearance distance, around five milimeters, can reduce electric power and time consumption in ice slurry generation. PTFE, more commonly known as Teflon, is suitable for a wide range of applications in industries as diverse as aerospace, the food and drink industry, pharmaceuticals and telecoms. The present study used variation of magnetic chemical pump RPM, scraper RPM, and salinity of seawater. The results show that the higher salinity results in the lower temperature of ice slurry generation and decreases ice slurry generation. The experimental condition with higher scraper RPM result in slower ice slurry generation. There is an optimum pump RPM to decreasing the temperature faster. Seawater with lower salinity was changed into ice slurry faster, increased the production of ice slurry, and consumed less electric power than that of higher salinity.
