The freezing rate of food products is a critical parameter in Process Engineering that directly dictates ice crystal nucleation and growth kinetics. Rapid freezing yields a high density of small, uniform crystals, whereas slow freezing promotes large, destructive dendritic structures that damage cellular membranes. This tool models the conduction-controlled freezing process to evaluate final crystal morphology and product quality.
