With the progress of the society,consumers have higher requirements for goods.As the promotion of small sealing and the development of supermarkets,the application of vacuum sealing machine is becoming more and more extensive,replacing hard packing gradually.The vacuum sealing machine can automatically draw the air from the bag and achieve the sealing process after the vacuum degree.It can also be filled with nitrogen or other mixed gases,and then the sealing process is completed.Vacuum sealing machines are often used in the food industry,because after vacuum sealing,food can resist oxidation to achieve long-term preservation.

Features for vacuum sealing machine:
1,Eliminate some air (oxygen) in the sealing container, which can effectively prevent spoilage of food.
2,(air tightness) good barrier property of sealing materials and sealing technology and strict requirements,can effectively prevent the sealing content material exchange,lose weight,avoid food flavor,and prevent the secondary pollution.
3,vacuum container inner gas has been ruled out,speeding up the heat conduction,it can improve the efficiency of thermal sterilization,also avoid the heating sterilization,packaging container cracking due to the expansion of gases.

In the food industry,vacuum sealing application is very common, various cooked products such as chicken leg,ham,sausage,grilled fish slices,beef jerky,etc.Pickled products such as all kinds of pickles and bean products,dried fruits and other foods that require fresh food are increasingly used in vacuum sealing.The shelf life of food is greatly extended by vacuum sealing.

Function and principle:
The main function of automatic food sealing machine is of  deoxygenize,in order to prevent food spoilage.The principle of vacuum tin can sealing machine is pull out the oxygen which in package and in food cells,makes microbial lose their survival environment.

Vacuum deaeration besides inhibiting microbial growth and reproduction, another important function is to prevent the be oxidation of the food, because the oil kind food contains A lot of unsaturated fatty acid,by the effect of oxygen oxidation,sour food,deterioration,in addition,the oxidation also make vitamin A and C loss,volatile substances in food pigment by the role of oxygen,make the color darker.Therefore, deoxygenation can effectively prevent food spoilage.

Vacuum sealing machine in addition to vacuum sealing of oxygen quality features,main and compressive strength,the air resistance,the preservation effect,can more effectively to make food for a long time to keep the original color,aroma,taste,shape,and nutritional value.
