The vacuum packaging machine may still be unfamiliar to many people , and even the awareness of vacuum preservation is relatively vague. There are a lot of people will ask: "With refrigerator, why do we need to use vacuum packaging machine vacuum machine What are the benefits??" Today to give you a brief introduction, why we use vacuum packaging machine.
Our most common way of keeping food fresh is to put in the refrigerator if you can't finish it, and put it in the refrigerator if you haven't finished it. I think that the low temperature of the refrigerator is enough to help us keep the food fresh. However, many people will find that when fresh food is put in, it will change color after a short time when it is taken out, and it may also be accompanied by the taste of other food in the refrigerator. There is a feeling that is hard to say. In fact, this is the air at work. Our lives are inseparable from air, and there is oxygen in the air, which we can’t do without. However, for food, oxygen accelerates the speed at which they become "mature". The low temperature of the refrigerator can only slow down the speed, but it is not effective. control. The result is that our food is put in the refrigerator to deteriorate and taste, or it can only be wasted cruelly or eaten cruelly. But the two results, whether it is extravagance or physical damage, is not a wise choice.
The emergence of the vacuum packaging machine has solved this problem very well. We store the food in a vacuum bag. After the air in the bag is extracted with a fresh vacuum machine, the food is in a vacuum state in the vacuum bag. Simply understand, That is, the oxygen component is isolated and the air is drawn away. Without oxygen, the food will be in a "frozen age state", and using it with the refrigerator can effectively extend the storage time of the food. However, it cannot be said that food can be stored permanently with a vacuum packaging machine. It can only be said that the storage time of food can be effectively extended . Another advantage is that the food is vacuum-packed and stored in the refrigerator, which can prevent all kinds of food from odor.
