The main function of
vacuum packaging (vacuum packaging) is to prevent spoilage by vacuum packaging,
and the main purpose of vacuum packaging is to prevent spoilage of
microorganisms, such as vacuum packaging It is to use this principle to take out
the oxygen in the packaging bag and food cells, so that microorganisms lose
their living environment. The experiment shows that when the oxygen
concentration in the bag is less than or equal to 1%, the growth and
reproduction speed of microorganisms will drop sharply. When the oxygen
concentration is less than 0.5%, most microorganisms will be inhibited and stop
breeding. (Note: vacuum packaging can not inhibit the reproduction of anaerobic
bacteria and the deterioration and discoloration of food caused by enzyme
reaction, so it needs to be combined with other auxiliary methods, such as
refrigeration, quick freezing, dehydration, high temperature sterilization,
irradiation sterilization, microwave sterilization, salt pickling, etc.)
In the process of vacuum packaging, the general needs of vacuum pump are
rotary vane vacuum pump, roots rotary vane vacuum unit, according to the
required vacuum degree, the vacuum pump needs to be selected is not the same,
can be equipped with the appropriate vacuum pump according to customer needs, if
you have questions about vacuum packaging machine special vacuum pump, you can
