Analisis Laju Kristalisasi Es Pada Cetakan Mesin Es Balok

Abstract

This study aims to analyze the crystallization rate of ice in a block ice machine mold using a Computational Fluid Dynamics (CFD)-based simulation. The research focuses on a variation with the coil temperature set at –20 °C and the initial water temperature at 25 °C. The simulation results indicate that the total freezing time required is 20 hours, which is consistent with the existing conditions of the block ice machine used as a reference. These findings confirm that the operational parameters produce a stable freezing performance, although further optimization remains possible to improve efficiency.
