As a result of the mass propagation of microorganisms, meat food materials still undergo spoilage during refrigeration, and most of the microorganisms easily carried by meat foods are bacteria and fungi. Common physical sterilization means include ultraviolet sterilization and ozone sterilization. The ultraviolet sterilization technology principle is that the molecular structure of the inner core protein of the microbial cell on the surface of the object is changed to cause death. The principle of ozone sterilization is as follows: firstly, the ozone acts on the microbial cell membrane to damage the constitution of the cell membrane, cause metabolic disorder and inhibit the growth of the cell membrane, and ozone continuously permeates and damages tissues in the membrane until death occurs.

s40: and if the second temperature is within the set temperature range of the refrigerating area or the second temperature is within the set temperature range of the refrigerating area, controlling the ozone generating module 14 to be started.
It should be noted that, since the micro-freezing region is the region of maximum ice crystal formation, part of the micro-structure of the microorganisms in the micro-cells of the micro-organisms in this region is damaged, so that the micro-organisms are dehydrated, the electrolyte concentration is changed, and the osmotic pressure of the micro-organisms is changed, thereby causing death of part of the micro-organisms. Therefore, before the sterilization and fresh-keeping device is used for sterilization, the sterilization and fresh-keeping device with the articles stored therein can be placed in a micro-freezing area for precooling.
In some embodiments, the refrigerator micro-freezing zone may have a set temperature interval of-5 to 0 ℃, the refrigerating zone may have a set temperature interval of 1 to 5 ℃, and the freezing zone may have a set temperature interval of-18 to-16 ℃. The control board 12 acquires the first temperature detected by the temperature sensor 15, and controls the ultraviolet sterilization module 13 to be started if the first temperature is within-5-0 ℃. After the control board 12 controls the ultraviolet sterilization module 13 to be started, the ultraviolet intensity of the ultraviolet sterilization module 13 is 0.01-0.5J/cm 2 The working time is 30-120 min.
After the ultraviolet sterilization module 13 finishes working, if the sterilization and fresh-keeping device is moved to the refrigerating area or the freezing area at this time, the temperature sensor 15 senses the temperature change of the temperature area and transmits the detected second temperature to the control board 12 because the set temperature of the refrigerating area or the freezing area is different from that of the micro-freezing area. After the control board 12 obtains the second temperature detected by the temperature sensor 15, if the second temperature is within 1-5 ℃ or within-18 to-16 ℃, the ozone generating module 14 is controlled to be started. After the control board 12 controls the ozone generating module 14 to be started, the ozone concentration of the ozone generating module 14 is 0.5-2 ppm, and the working time is 30-60 min.
It should be noted that, if the ultraviolet sterilization module 13 stops working and the sterilization and fresh-keeping device does not move, any module in the device is not started to work.
Illustratively, the sterilizing and fresh-keeping device is placed in a micro-freezing compartment with the temperature of the refrigerator reaching-3.5 ℃, the ultraviolet sterilization module 13 is started, and the ultraviolet sterilization intensity is controlled to be 0.05J/cm 2 The sterilization time is 30min, and the sterilization efficiency can reach 99 percent at the moment. If the fresh meat needs to be kept fresh for less than 15 days, the fresh meat sterilized by the steps can be continuously stored in a sterilizing and fresh-keeping device to be kept in a micro-freezing area. If fresh meat needs to be preserved for more than 15 days, the fresh meat sterilized by the steps can be continuously stored in the sterilization and preservation device and moved to a freezing area, and as the preset temperature of the freezing area is different from the preset temperature of the micro-freezing area, when the temperature sensor 15 of the sterilization and preservation device collects temperature change, the collected information is fed back to the control board 12, the control board 12 starts the ozone generation module 14 to work for 30 minutes, the ozone concentration is controlled to be about 0.5ppm, and the sterilization efficiency is highest at the moment.
The fresh meat subjected to the micro-freezing precooling, ultraviolet sterilization for 30min and ozone sterilization for 30min is subjected to closed freezing storage in a sterilization and fresh-keeping device, and the fresh meat stored in the state is prolonged by more than 20 days compared with the fresh meat stored in a micro-freezing area directly, and is prolonged by more than 2 months compared with the fresh meat stored in a freezing area directly.
