How do vacuum bags save food

Vacuum bags are divided into two kinds of ordinary smooth and textured vacuum bags, which are pumped by vacuum machines. According to the different types of food, set the appropriate vacuum time. Then according to the material and thickness of the bag, select the sealing temperature and time, and finally the bag to be vacuumed is arranged on the sealing strip of the vacuum machine to complete the evacuation and sealing.

First, choose a vacuum bag

The general vacuum bag has two kinds of ordinary smooth vacuum bag and grain vacuum bag. Both bags use a vacuum machine to pump air. The ordinary smooth surface is a vacuum machine with a suction nozzle. Grain bags can be used with empty slots. There are also large vacuum machines that work with both types of bags.

Second, set the time temperature

According to the vacuum requirements of different foods, set the vacuum time, generally 20 to 30 seconds, the longer the time, the higher the vacuum degree. Adjust the sealing temperature and time according to the material and thickness of the vacuum bag. Before packaging, you can test the temperature and time, and the general temperature is adjusted in 2 ~ 3 gears, and the time is 3 ~ 4 seconds.

Three, vacuum

The packed food packaging bag is neatly arranged on the sealing strip of the machine, when the packaging needs vacuum, close the vacuum chamber, the whole food vacuum, sealing, printing packaging procedure is completed by the electrical automatic program. After vacuum packaging, the air in the bag is scarce and the oxygen content is low, which inhibits the survival of microorganisms and has a good fresh-keeping effect.
