Semi Automatic Modified Atmosphere Packaging Machine

Modified Atmosphere packaging (MAP) for fresh meat, using modified atmosphere technology to fill a certain proportion of mixed gas (Oxygen, Carben Dioxide and Nitrogen) into the package and seal it to isolate the fresh meat from the outside world.
The mixed gas in the MAP package can play a role in inhibiting the growth and reproduction of microorganisms and preventing its oxidation, so as to achieve the purpose of prolonging the shelf life of fresh meat. In addition to keeping the meat fresh, modified atmosphere packaging can clearly show the meat quality and promote product sales.
The sealed and easy-to-tear design of MAP package can give customers a high-quality consumer experience.

MAP tray sealers can be applied to many products, such as fresh meat, vegetable, fruits, cooked meat, products containing protein, bread and baked goods, and certain medical and technical products.
One of the advantages of modified atmosphere packaging is extended shelf life and quality assurance, as well as the protection of product during handling and transportation process. When packaging food, the use of modified atmosphere package can extend the shelf life without the need for food additives. Industrial and consumer products can prevent corrosion by using modified atmosphere package. In the area of medical technology, modified atmosphere package can protect the sensitive medical products.

Qualified modified atmosphere packaging machine (MAP) should conform to two key requirements, they are: high gas replacement rate and low gas mixing accuracy error rate. These two key indexes are needed when judge the quality of MAP machine. Shanghai Sanjing Machinery Co., Ltd deeply know the importance of the above two points and keep working towards the best indicator and until now the result is very satisfactory!

When cooked food are packaged in modified atmosphere package (MAP), the mixing ratio of fresh gas is: nitrogen (N2) 64% ~ 66%, carbon dioxide (CO2) 34% ~ 36%, gas replacement rate ≥98%. Since many microorganisms (bacteria) need O2 to grow and reproduce, reducing oxygen content can slow down the growth rate of bacteria (except anaerobic bacteria). The results showed that the reasonable mixture of N2 and CO2 formed a broad spectrum of bacteriostasis, color and taste protection layer on the food surface, and preserved cooked food under low oxygen environment. Therefore, when the error rate and replacement rate of gas mixing precision cannot reach the target, its bacteria-inhibiting and fresh-keeping effect is basically ineffective.

The modified atmosphere packaging technology will play a role in the intelligent packaging era. With some food and vegetable fresh-keeping products becoming the mainstream of food consumption and occupying an increasing share in the domestic and foreign markets, the application of modified atmosphere packaging machine will greatly prolong the shelf life of food.
With replaceable sealing and cutting mold of modified atmosphere packaging machine, users can change the shape and specification of the tray at any time.

Adopting microcomputer programmable controller and touch screen control system, setting of each parameter is highly accurate and the operation is stable and reliable. According to the properties of packaging materials, you only need to set the packaging parameters for once and then it can continuously and completely for all the packaging steps.
The modified atmosphere packaging equipment is simple and convenient to operate. The double-start safety switch can ensure the safety of operators. The whole automatic packaging process can be completed by touching the start switch.

Controlled atmosphere packaging is a new type of food preservation technology which will replace the air in the package by mixed gas (usually CO2, N2 and O2 with certain proportion). It adopts the different role of such mixed gas to inhibit the growth of microorganisms which will cause food spoilage, and reduce the respiratory rate of active food (plant-based foods such as fruit and vegetable) . In this way, it will keep food fresh and extend the shelf life. The food in modified atmosphere package will maintain the original color, flavor, taste, shape and nutrition of the food.

Modified atmosphere packaging tray sealer has the characteristics of high automation, reliable quality, long service life, simple maintenance process, large production and wide range of applicability. According to the types of fresh gas needed by different foods, three kinds of fresh gas, two kinds of fresh gas and one kind of fresh gas can be selected to meet different needs of users.
High precision gas mixing system can be used to rapidly convert different types and mixing ratios of fresh gas according to different food preservation requirements, so as to achieve the fresh-keeping effect required by customers.

For modified atmosphere packaging machine (MAP), the natural gas in the packages is replaced by the appropriate gas at a certain proportion (Nitrogen, Oxygen, Carbon Dioxide) for the product.
In order to maintain the shape, color and freshness of the product, the air in the modified atmosphere package is replaced by a mixture of gas suitable for the product. This modified atmosphere is usually composed of carbon dioxide, nitrogen and oxygen.
