Vacuum Tumbler actual requirement depends on the specific degree of vacuum packaging may be. After vacuum packaging After the articles are loaded into the airtight container , the container prior to sealing the vacuum draw , so that substantially no air sealing technique within a packaging container .
Vacuum packaging method according exhaust , divided into two heat exhaust ventilation and sealing . The former is obtained by filling a food packaging container is heated by the thermal expansion of the air as well as food after the evaporation of water in the packaging container is discharged in the air , and then after sealing , cooling, so that a certain degree of vacuum containers .
Is vacuum sealed in the vacuum packaging machine , the packaging container by the vacuum pump for the extraction of air , after reaching a certain degree of vacuum immediately seal the packaging Tumbler vacuum container is formed in a vacuum state . Comparison and exhaust heat , compared with the exhaust sealing method can reduce the heating time of the content , better color, flavor and preservation of food , therefore , the sealing method is widely applied to compare pumping , especially for exhaust heat conduction slow the products are more suitable .
