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
The present invention relates to a kind of controlled atmosphere fresh-keeping packing machine, particularly a kind of cold fresh meat controlled atmosphere fresh-keeping packing machine, belongs to food fresh keeping machinery technical field.
Background technology
Meat is divided into hot fresh meat, cold fresh meat and chilled meat, and wherein hot fresh meat refers to the meat after just butchering, cold fresh meat refer to hot fresh meat through low temperature the meat after 0-4 ℃ of cooling a period of times, chilled meat refers to the meat through freeze preservation.
Nutritionist thinks that live pig slaughters and in rear body, have a kind of enzyme, and as edible immediately, its nutritive value is rear edible not as first cooling on the contrary, and the cooling enzyme that makes loses activity, and realizes the process of acid discharge, and the softness that pork quality becomes is savory, and mouthfeel is good, is conducive to absorption of human body.And chilled meat nutrition meeting in refrigerating process is run off, also be not as good as cold fresh meat.
The storage of cold fresh meat and fresh-keeping way have several fresh-keeping forms such as vacuum packaging, nitrogen-filled packaging and compound controlled atmospheric packing conventionally.Wherein vacuum and nitrogen-filled packaging all can make meat become lavender, and meat is not very fresh, and therefore, what current cold fresh meat adopted is all the way of compound controlled atmospheric packing.
At present, controlled atmosphere adopts controlled atmosphere fresh-keeping packing machine conventionally, and the vacuum performance of current controlled atmosphere fresh-keeping packing machine is poor, and remaining oxygen is high, and gas mixes inaccuracy, therefore causes cold fresh meat fresh keeping time short, and fresh-keeping effect is poor.
Summary of the invention
Goal of the invention: the object of this invention is to provide a kind of controlled atmosphere fresh-keeping packing machine, a kind of cold fresh meat controlled atmosphere fresh-keeping packing machine particularly, its vacuum effectiveness good, after packing, remaining oxygen is low, and controlled atmosphere atmosphere gas mixes accurately, and after packing, fresh keeping time is long, good refreshing effect.
Technical scheme: a kind of controlled atmosphere fresh-keeping packing machine; comprise conveying mechanism, air interchanger and hot sealing device; described air interchanger comprises vacuum extractor, gas mixer and gas filled device; described conveying mechanism connects described air interchanger and described hot sealing device; before described vacuum extractor is arranged on described gas filled device; described gas mixer connects described gas filled device; for described gas filled device supply atmosphere gas; also comprise capping film mechanism, described capping film mechanism is described hot sealing device supply capping film.
Because adopting, controlled atmosphere fresh-keeping packing machine provided by the invention first vacuumizes then inflation, with the comparison of traditional washing compensation type controlled atmospheric packing, can save the gas that is mixed, save packing cost, the injuries such as gassing of also avoiding discharged miscellaneous gas to cause operating personal simultaneously.
Further, described vacuum extractor comprises vacuum pump and air-tight chamber, and described vacuum pump is communicated with described air-tight chamber, on described air-tight chamber, is provided with air tight door, and it is inner that described hot sealing device is arranged on described air-tight chamber, and described gas filled device is communicated with described air-tight chamber.
Owing to adopting totally enclosed airing form, saving gas more, and hot sealing device etc. is arranged in a whole air-tight chamber, has avoided producing in course of conveying the possibility of gas leakage.
Described vacuum pump is hyperoxia vacuum pump.Adopt hyperoxia pump anti-leak-stopping oxygen effectively, can effectively ensure operator and user's safety of life and property.
Beneficial effect:
The present invention, by adopting fully enclosed vacuum chamber substitution gas technology, can guarantee the high rate of displacement of gas, and after packing, residual oxygen content reaches minimum, can effectively guarantee the precision that is mixed of the composite gas in packing, and fresh-keeping effect is better.
Advantage and disadvantage of the present invention, the non-limitative illustration by preferred embodiment below is for illustration and explanation, and these embodiment, only provide as an example with reference to accompanying drawing.
Accompanying drawing explanation
Fig. 1 is the functional block diagram of the embodiment of the present invention one;
