Different Vacuum Packaging for Rice

Application of Rice Vacuum Packaging Machine: It is a common practice to use vacuum packaging machine to pack rice, which can reduce the volume of rice and extend its shelf life. Usually, rice is processed by a special rice vacuum packaging machine, which has three main methods of packaging rice.

There are three ways of vacuum packaging rice: Rice vacuum packaging machine is a type of food vacuum packaging machinery mainly used for rice packaging. Vacuum packaged rice has a small footprint, long shelf life, and beautiful appearance, so vacuum packaged products are often seen when purchasing rice. The three packaging methods of rice vacuum packaging machine are as follows:

1.Ordinary vacuum packaging method: Use vacuum packaging bags to pack rice, and then put it into a rice vacuum packaging machine for vacuuming operation. This method is quite common, but it is suitable for small-scale packaging, and the appearance of the packaged rice is not aesthetically pleasing enough.

2.Vacuum packaging method for rice bricks: Before packaging, make acrylic molds and perform special treatment on the packaging bags to make them cubic in shape. Then put the rice into the rice vacuum packaging machine for vacuum packaging, and the packaged rice looks like a brick with a beautiful appearance.

For the first and the second way, we can think about using double chamber vacuum packaging machine to pack .

3.Modified atmosphere vacuum method: Use a rice vacuum packaging machine with inflation function to fill carbon dioxide and nitrogen during the vacuum packaging process. Rice has the ability to adsorb carbon dioxide, form a protective layer, reduce changes in fatty acids, total acids, reducing sugars, and viscosity, thereby extending the shelf life. Nitrogen can reduce the oxygen concentration inside vacuum packaging, inhibit the growth of microorganisms in rice, maintain rice quality, and prevent mold and insect growth.

The shelf life of rice vacuum packaging: After being vacuum packaged by a vacuum packaging machine, the shelf life of rice can be extended. Generally speaking, vacuum packaged rice can have a shelf life of about one to one and a half years without opening the bag or leaking air. However, if the bag has already been opened or there is a leak, the shelf life will be greatly shortened, usually only about three months. It should be noted that the shelf life here is calculated from the production date and only applies to unopened and leak proof states. If the rice has already been opened or leaked, its shelf life will be further shortened.
