There are several ways to pack rice with rice vacuum packaging machine

Abstract: It is very common to use a vacuum packaging machine to vacuum package rice. Vacuum-packed rice is smaller in size and has a longer shelf life. It is generally packaged with a special rice vacuum packaging machine. There are three main ways for rice vacuum packaging machines to package rice. The common method is to put it directly into the packaging machine for packaging. You can also make a mold and package it into rice bricks. A vacuum packaging machine with an inflatable function can also inflate the rice. Vacuum-packed rice can be stored for about one to one and a half years if the bag is not opened and air leaks, but if the bag is opened or air leaks, it can only be stored for three months. Let’s learn more about it together. 1. There are several ways to package rice with rice vacuum packaging machine

Rice vacuum packaging machine is a type of food vacuum packaging machinery. It is mainly used to package rice. Vacuum-packed rice occupies less area and has a longer shelf life. It is long and beautiful in appearance, so when buying rice, many of it is vacuum packed. There are three main ways of packaging rice with vacuum packaging machines:

1. Ordinary vacuum packaging method

Pack the rice in vacuum packaging bags and put it directly into the rice vacuum packaging machine for vacuuming. The finished product is vacuum-packed rice. This method is relatively common, but the packaging volume is relatively small. , and the packaging is not beautiful enough.

2. Rice brick vacuum packaging method

This vacuum packaging method requires making an acrylic mold before packaging, and the bags used to package the products also need special treatment. , make a cubic packaging bag, and then put it into a rice vacuum packaging machine for vacuum packaging. The packaged rice is like a brick, which is more beautiful.

3. Inflatable packaging method

This method requires the use of a rice vacuum packaging machine with an inflatable function. Carbon dioxide and nitrogen are filled in during vacuum packaging, because rice has the ability to absorb carbon dioxide. The ability of nitrogen can form a protective layer to reduce the changes in fatty acids, total acids, reducing sugars, and viscosity of rice and extend the shelf life; nitrogen can reduce the oxygen concentration in vacuum packaging, inhibit the growth of microorganisms in rice, and can maintain Rice quality, prevention of rice mildew and insect infestation.

2. How long can rice be stored in vacuum packaging

Using a vacuum packaging machine to vacuum-pack rice can extend the shelf life of rice. So how long can vacuum-packed rice be stored?

Generally speaking, the national standard for the shelf life of vacuum-packed rice is 18 months. Depending on the processing method and vacuum packaging method, the shelf life of vacuum-packed rice purchased on the market may be 12 months or 18 months. months, but it should be noted that the time here is calculated from the production date shown on the outer packaging, and it is unopened and air-tight; if the bag has been opened or air leakage occurs, then the rice If it is no longer in a vacuum packaging state, the shelf life will be greatly reduced. Generally, it may expire in about three months.
