Problems solved by technology

[0005] At present, modified atmosphere preservation usually adopts modified atmosphere packaging machine. The current modified atmosphere packaging machine has poor vacuum performance, high residual oxygen, and inaccurate gas mixing, which leads to short preservation time and poor freshness effect of chilled fresh meat.

Abstract

The invention relates to a modified atmosphere fresh-keeping packaging machine which comprises a conveying mechanism, an air interchanger and a heat-seal device. The air interchanger comprises a vacuumizing device, a gas mixing device and an inflating device. The conveying mechanism is connected with the air interchanger and the heat-seal device. The vacuumizing device is arranged in front of the inflating device. The gas mixing device is connected with the inflating device to supply protective gas for the inflating device. The modified atmosphere fresh-keeping packaging machine further comprises a cap-sealing membrane mechanism used for supplying cap-sealing membranes for the heat-seal device. According to the modified atmosphere fresh-keeping packaging machine, a totally-closed vacuum chamber gas displacement technology is adopted, the high gas displacement rate can be guaranteed, the content of residual oxygen in a packaging box can reach the minimum, the mixing accuracy of composite gas in a packaging tray can be guaranteed effectively, and the fresh-keeping effect is better.

Description

technical field [0001] The invention relates to a modified atmosphere fresh-keeping packaging machine, in particular to a modified atmosphere fresh-keeping packaging machine for chilled fresh meat, and belongs to the technical field of food fresh-keeping machinery. Background technique [0002] Meat is divided into hot fresh meat, cold fresh meat and frozen meat, of which hot fresh meat refers to the meat just after slaughtering, cold fresh meat refers to the meat after the hot fresh meat has been cooled at a low temperature of 0-4 ℃ for a period of time, and frozen meat is Refers to frozen meat. [0003] Nutritionists believe that there is an enzyme in the body of live pigs after slaughtering. If they are eaten immediately, their nutritional value is not as good as being eaten after cooling. Cooling makes the enzyme inactive and realizes the process of expelling acid. The texture of pork becomes soft and fragrant, and the taste is good. Conducive to human absorption. Froz...
