1、排除了包装容器中的部分空气（氧气），能有效地防止食品变质。2、采用阻隔性（气密性）优良的包装材料及严格的密封技术和要求，能有效防止包装内容物质的交换，即可避免食品减重、失味，又可防止二次污染。
3、真空包装容器内部气体已排除，加速了热量的传导，这即可提高热杀菌效率，也避免了加热杀菌时，由于气体的膨胀而使包装容器破裂。
在食品行业，真空包装应用非常普遍，各种熟制品如鸡腿、火腿、香肠、烤鱼片、牛肉干等；腌制品如各种酱菜以及豆制品、果脯等各种各样需要保鲜的食品越来越多地采用真空包装。经过真空包装的食品保鲜期长，大大延长食品的保质期。
名称参数 抽真空能力40m3/h 工作循环15-40秒/次 尺寸1310×800×1150mm 电压220V/50HZ（380V/50HZ）可选 功率2.0KW
1. Some air (oxygen) in packing container is eliminated, which can effectively prevent food from spoilage.
2. The use of good barrier (air tightness) packaging materials and strict sealing technology and requirements can effectively prevent the exchange of materials in the packaging content, which can avoid food weight loss, loss of flavor and secondary pollution.
3. The gas inside the vacuum packaging container has been eliminated, which accelerates the heat conduction, which can improve the thermal sterilization efficiency and avoid the packaging container rupture due to the expansion of gas during heating sterilization.
In the food industry, vacuum packaging is widely used in various cooked products, such as chicken leg, ham, sausage, grilled fish slices, beef jerky, etc.; pickled products such as various pickles, bean products, preserved fruits and other foods that need to be kept fresh are more and more vacuum packaging. After vacuum packaging of food preservation period is long, greatly extending the shelf life of food.
