Working principle of modified atmosphere box packaging machine


2022-07-29 16:41

The modified atmosphere box packaging machine adopts the function of "modified atmosphere fresh-keeping", and its working principle is to change the fresh-keeping time of food by changing the gas environment. It puts food into a box, and then draws out the air in the box through a vacuum pump, and then fills it with mixed gas that can maintain the freshness of food. The mixed gas is mixed in equal proportion by the gas mixer according to different food characteristics. The gas that can keep food fresh is generally divided into three types: oxygen, nitrogen and carbon dioxide. The role of oxygen is to keep the color of food unchanged, and nitrogen plays a filling role to keep the positive pressure in the box, prevent the air outside the box from entering the box and protect the food. Carbon dioxide can inhibit the reproduction of microorganisms. The three gases can be mixed in different proportions according to different food requirements, or meet the packaging requirements of different foods.
Box shape difference of different types of modified atmosphere packaging machinery. The successful development of modified atmosphere box packaging machine has brought snacks from all over the world to our table. The types of boxes we usually see are also various, such as rectangle, circle and square. What model of modified atmosphere packaging machine are used to pack these boxes? It was originally related to the mold of the air conditioning box packaging machine. Before packaging products, the CA box packaging machine needs to customize a suitable mold according to the shape of the box, and then make equipment according to the size of the mold, so as to meet the packaging requirements of different box types.
The appearance of such a packaging equipment not only meets the consumer's demand for ethnic snacks, but also brings business opportunities to food enterprises and drives the development of food enterprises. This is also the product of scientific and technological progress. With the continuous development and progress of China's science and technology, I believe that more functional food packaging equipment will appear in front of us one after another!

Summary of use and maintenance methods of continuous stretch film packaging machine

With the arrival of the automation era, many enterprises have begun to transform. The original manual operation has been gradually replaced by machines. Automated equipment can not only improve the work productivity, but also free the labor from the heavy work.

Application of Stretch Film Packaging Machine

For a long time, food packaging is mainly based on traditional technology. Such trivial and heavy repetitive manual labor is difficult to complete large-scale production. The working environment is poor, the labor intensity of workers is high, the yield of good products is low, and the stability of product quality is poor.

How much do you know about automatic stretch packaging machine

How much do you know about the types of automatic stretch film packaging machines? Let's have a look. Automatic stretch film packaging machine is a universal packaging machine, and different types are also calculated according to the working capacity of the product.

Selection principle of double-sided stretching vacuum packaging machine

The stretching vacuum packaging machine is divided into single-sided stretching vacuum packaging machine and continuous double-sided stretching vacuum packaging machine. Its working principle is to use the forming die to heat the film, then use the forming die to punch it into the shape of a container, and put the package into the formed lower film cavity.
