It is very important to keep the freshness up of fish product because fish will quickly decay after it is caught. Ice slurry is one of the best cooling mediums generated through refrigeration system utilizing sea water as its base material. Ice slurry can keep the freshness and also increase the lifetime of the fish product, because ice slurry suppresses bacterial decomposition rate. In this study, the production rate of the ice slurry generator coated by teflon was investigated. The rotational speed of the pump and scrapper were varied at 1064 – 1242 RPM and 335 – 423 RPM. The sea water was also varied at 10 ppt – 27 ppt. The optimum production rate of ice slurry and salinity variation has been obtained. Increasing the rotational speed of pump and scrapper with higher water salinity of seawater will decrease production rate of ice slurry. It was found that the best production rate of slurry ice generator in this research was 0.284 Ton/12 Hours produced by 10 ppt salinity of seawater with 335 RPM rotation on the scraper and 1064 RPM on the pump. Ice slurry could be a good option for long shipping time by keeping the fish quality.
