Hangzhou Yongchuang has long been committed to the research and development of vacuum packaging machine, absorbing foreign advanced technology, has developed four series of vacuum packaging machine: food vacuum packaging machine, small vacuum packaging machine, desktop vacuum packaging machine, single-chamber vacuum packaging machine, double-chamber vacuum packaging machine, three-dimensional bags of vacuum packaging machine, equipment have reached the level of Europe and the United States. And provide quality, technology, vacuum packaging machine price guarantee 100% satisfaction, recognized by the majority of customers. The company produces vacuum packaging machine series products suitable for a variety of food, meat products, seafood, fruits and vegetables, pickles, cooled meat, pharmaceutical products, hardware components, medical equipment, etc. for vacuum, inflatable, paste the body of the packaging machine.
The principle of vacuum packaging is: because of the food mold deterioration caused mainly by microbial activity, and most of the microorganisms (such as molds and yeast) needs oxygen to survive, and vacuum packaging is to use this principle, the bag and food cells within the oxygen pumped off, so that the micro-objects to lose the "survival of the environment". Experimental evidence: when the oxygen concentration in the bag ≤ 1%, the growth and reproduction of microorganisms on the sharp decline in the rate of oxygen concentration ≤ 0.5%, most of the microorganisms will be inhibited and stop reproducing. (Note: vacuum packaging can not inhibit the reproduction of anaerobic bacteria and enzyme reactions caused by food spoilage and discoloration, so it is also necessary to combine with other auxiliary methods, such as refrigeration, quick-freezing, dehydration, high temperature sterilization, irradiation sterilization, microwave sterilization, salt pickling, etc.).
