| To promote the development and application of R744 transcritical refrigeration system in specialty fat processing, the working principles and advantages of R744 transcritical refrigeration systems were reviewed, and a comparative analysis was conducted between two shortening production lines employing R717 refrigeration system and R744 transcritical refrigeration system, respectively. The comparison covered process schemes, power consumption, and product quality indicators including solid fat content, hardness, extensibility, toughness, and baking performance. The results showed that R744 transcritical refrigeration system exhibited significant energy-saving benefits, improving performance and stability, environmental sustainability, and wide operating condition adaptability. Compared with R717 system, R744 transcritical refrigeration system improved production efficiency, achieved an average annual electricity saving rate of 3201%, and delivered products with better temperature resistance, improved extensibility, toughness, and baking performance, along with stable solid fat content. In conclusion, as a natural refrigerant, R744 demonstrates high efficiency, environmental friendliness, and cost-effectiveness, indicating broad application prospects in the specialty fat processing industry. |
