| Abstract: | In dairy processing, β-lactoglobulin, the predominant component of whey protein solutions, significantly contributes to fouling in plate heat exchangers, which are involved in milk derivative production. However, observing the formation and growth of fouling under experimental conditions within closed plate heat exchangers presents challenges. As a result, simulation has emerged as an alternative approach that has attracted considerable attention. A validated simulation model is essential for achieving a more accurate description and prediction of the fouling behavior of whey solutions. In this work, a 2D dynamic model for plate heat exchangers was proposed based on the measured kinetics of denaturation and deposition obtained by experiments. In this 2D dynamic model, the entire plate heat exchanger is simulated to account for real temperature variations of the product along the plate heat exchanger path. This innovative approach not only reflects the dynamic interplay between fouling and bulk liquid but also serves as a reliable tool for predicting milk fouling. It promises to enhance our understanding of milk fouling mechanisms, potentially transforming practices in the dairy industry by enabling more effective fouling management strategies.
