According to the UNs data, the greenhouse gas discharged by the global meat processing industry accounts for 18% of the total emissions, even more than that of transportation industry.In the meat freezing and refrigeration procedure, the energy consumption of refrigeration accounts for more than 85% of the total energy consumption, with the reasons of unreasonable standardization solution configuration in the refrigeration system, low construction standard and extensive management, etc.This paper has made a research on the energy-saving technology from the respects of refrigeration system design optimization, cold bridge occurrence control, storage door air curtain structure reconstruction, defrostation form improvement, LED energy-saving lamp application and so on, among which some energy-saving measures have certain reference value for the meat food processing enterprises in our country to make energy-saving reformation.
