Packing

Vacuum packaging is a packaging process that extracts air from the packaging before sealing.

Food Packaging and Processing

With the changes in social consumption habits and the increasing emphasis on food safety, the application of vacuum technology in packaging and food processing is becoming more and more widespread. Food processing covers a wide range of applications, and vacuum is often used in packaging for different characteristics. Usually, vacuum plays a crucial role in packaging technology and production. The use of vacuum technology can efficiently and accurately achieve packaging molding, thermoforming, and coating. In addition, vacuum technology can be used for movement, transportation, unpacking, and sealing. During the packaging process, vacuum can also be used to feed and embed the items to be packaged. The use of vacuum technology in food packaging technology helps to maintain the freshness of food for a long time without compromising its quality. Using MAP (Modified Atmosphere Packaging Technology) for fresh food can maintain the appearance, freshness, and taste of the food.

Food packaging

By reducing the residual oxygen concentration, the growth of aerobic bacteria is restricted, which can generally extend the storage period by 5-10 times. In addition, vacuum packaging can prevent the evaporation of ingredients to maintain the original flavor and texture, and can also reduce surface dehydration and hardening caused by dry and cold air flow, preventing secondary pollution during transportation.

Chamber packaging machine: The chamber packaging machine can be a single chamber or double chamber type, with or without a belt conveyor. This type of model operates in a rhythmic cycle, pumping approximately 1 millibar from atmospheric pressure every 0.5-2 minutes. Typical vacuum system: circular rotary large bag packaging machine,

If the front vacuum pump is far away from the machine, a single-stage rotary vane pump or dry pump can be combined with a Roots pump.

Modified atmosphere packing

MAP modified atmosphere packaging includes two steps: evacuation and inflation. According to different needs, there will be one or more extractions and inflation cycles to create a protective atmosphere inside the bag
