Summary
Food waste presents a global challenge to food security and sustainability while contributing to substantial emissions and energy consumption. Efficient cooling and freezing systems using natural refrigerants offer a sustainable solution to reduce food loss and waste in the food supply chain, particularly by preventing the loss of raw materials. Plate freezers are essential components in modern automated production and processing facilities for freezing processed foodstuffs. This study aimed to design a test facility for a real-sized industrial plate freezer that can be integrated into a dedicated CO2 refrigeration system in the laboratory infrastructure. With CO2 liquid circulation inside the plates, the unit can deliver over 100 kW of cooling capacity at an evaporation temperature ranging from -30 to -50 °C. Additionally, a numerical model was developed for the proposed freezing system and the freezing performance was investigated for different evaporation temperatures.
