How long can the box-type modified atmosphere packaging machine keep cooked food fresh? What kinds of gases are filled in cooked food? This is a professional problem. The fresh-keeping time of cooked food packaged by box-type modified atmosphere packaging machine is usually 7 ~ 15 days. The principle of fresh-keeping of cooked food by modified atmosphere locking is to inhibit bacterial growth, prevent food oxidation and reduce water evaporation, which can achieve good results without a single device. We need to use the fence principle of food safety to ensure food safety in every link:
1. Pre-packaging treatment, raw materials and production process formula. The control of precooling before packaging may lead to food deterioration.
2. Packaging device, the stability and accuracy of the packaging device is a powerful guarantee for the fresh-keeping packaging of the modified atmosphere lock, because it is only after it is opened that it can be known whether it has gone bad, and the products packaged by the unstable device may cause food deterioration without knowing it.
3. Storage temperature. Low temperature is the basic premise of modified atmosphere packaging. Without low-temperature modified atmosphere packaging, it is meaningless unless new additives for national food safety are added.
4. Appropriate packaging materials can enhance the appearance value of packaging, while different air permeability, water permeability and oil permeability will bring different effects.
In short, it is not impossible for professional manufacturers to provide professional solutions, use good packaging devices and lock fresh packaging at low temperature for half a month.
Note: The half-month fresh-keeping period here is not only sensory fresh-keeping, but also meets the national food safety standards.
The fresh-keeping gases in modified atmosphere packaging of cooked food are nitrogen, oxygen and carbon dioxide, and different products use different mixed fresh-keeping gases. Nitrogen and carbon dioxide are usually used.
The difference between the modified atmosphere packaging machine and the inflatable packaging machine is that it uses nitrogen, oxygen, carbon dioxide and other commonly used fresh-keeping gases to replace the gas in the package, so as to preserve the color, taste, quality and shape, inhibit bacterial reproduction and be more sanitary (boxed Zhou Heiya is the used modified atmosphere packaging machine). Inflatable packaging machine is a package filled with a single gas. Generally, inflatable packaging refers to packing in bags with nitrogen-filled packaging machine to achieve quality-guaranteed packaging, reduce the contact between products and air, inhibit the growth of bacteria and achieve quality-guaranteed effect (bagged potato chips are a typical case). Modified atmosphere packaging is mainly aimed at products with high requirements for freshness, appearance and hygiene, while inflatable packaging machines have relatively low requirements.
What is modified atmosphere packaging machine is not clear, that is, vacuum packaging of lunch boxes. Let's make a stunt, called modified atmosphere fresh-keeping machine.
Modified atmosphere packaging is a mixture of various gases (oxygen, carbon dioxide, nitrogen, etc.). ) into the fresh-keeping mixed gas of the product. Then it is replaced in the box or bag with high precision (the replacement rate is 99.5%), which prolongs the fresh-keeping period of the product and ensures the quality, shape, color and hygiene of the product. Modified atmosphere packaging is not only high-precision but also hygienic, so cold chain production line is very important. Many customers mistakenly believe that buying a modified atmosphere packaging machine to go back and pack can achieve the preservation effect. Modified atmosphere packaging is to inhibit the growth of bacteria, prevent food oxidation and reduce water evaporation, and it can achieve better results without a single device. We need to use the fence principle of food safety to ensure food safety in every link:
1. Pre-packaging treatment, raw materials and production process formula. The control of precooling before packaging may lead to food deterioration.
2. Packaging device, the stability and accuracy of packaging device is a powerful guarantee for modified atmosphere packaging. Because you can't know whether it will go bad until you open it, the products packaged by unstable equipment may cause food deterioration without knowing it.
3. Storage temperature. Low temperature is the basic premise of modified atmosphere packaging. Without low-temperature modified atmosphere packaging, it is meaningless unless new additives for national food safety are added.
4. Appropriate packaging materials can enhance the appearance value of packaging, while different air permeability, water permeability and oil permeability will bring different effects.
In short, it is not impossible for professional manufacturers to provide professional solutions, use good packaging equipment and keep fresh packaging at low temperature for half a month.
Note: The half-month fresh-keeping period here is not only sensory fresh-keeping, but also meets the national food safety standards.
There are many manufacturers of modified atmosphere packaging machines for pork, and it would be best if we could make a field trip. Because some people have different weights when they rush into the mixture, the time for meat quality insurance is also different. The color of the meat is different, so it's best to look at it on the spot and understand the specific situation.

The technology market of modified atmosphere packaging machine is very chaotic, and the choice of modified atmosphere packaging can not be decided only by the price. The quality of equipment produced by a large number of small domestic manufacturers is not up to standard and cannot be sold after sale. We can't decide until we have a field trip.
Ask several manufacturers of modified atmosphere packaging machines to see how big equipment you need. This can be customized.
How much is this model of 560 automatic modified atmosphere packaging machine? 560 is not standard. I don't know your specific demand and quotation, but there are millions of automatic modified atmosphere packaging machines. According to the actual demand, the price is naturally different with different configurations. For example, how much gas does the gas mixing system need and how much production speed does it need? Buying equipment mainly depends on whether it suits your own needs, followed by quality, after-sales service and finally price.
