Ice slurry is the right medium to maintain the quality of fish catches for the cooling process, because ice slurry can cool the product faster and the growth of bacteria becomes slower without damaging the product. The motivation in this study that during the flow process of ice slurry, the lower viscosity is needed so that the application of ice slurry is more efficient and easier to flow. This research aims to analyze the visualization of ice slurry flow with observing rheology in a spiral pipe which is added by glycol toward the characteristics of the fluid flow. The initial concentration of food-grade propylene glycol was 15% on ice slurry. Then its fluid flowed on the spiral pipe with 6.7 mm of pitch per-diameter and compared to horizontal circular pipe with 1 inch of diameter, each pipe has 1.2 m of length. At that time, pressure drop, mass flow rate and temperature of ice slurry were measured, simultaneously. The result is friction coefficient in spiral pipes lower than horizontal circular pipes so that the lower viscosity occurs on the spiral pipe. Besides, the visualization shows that the flow of ice slurry will be homogenous on higher Froud Number. Finally, The spiral pipe more effective to flow ice slurry than the circular pipe, this phenomenon is caused by the homogeneous flow in the spiral pipe occurring faster.
