1. This machine is a fully automatic vacuum sealing machine, and it can also be used for sealing alone. This machine is suitable for dry goods and wet goods without fluid
2. The vacuum must be a textured bag or a bag with folded corners, other types of bags only support single sealing
3. There are active molecules in fresh vegetables and fruits that will release oxygen, and the bag will swell after being vacuumed. This is a natural phenomenon and has nothing to do with the machine and the bag. (Solution: the freezing effect is better~)
4. The principle of preservation: several conditions for food preservation are low temperature and anti-oxidation, anti-moisture, anti-bacteria, and anti-flavor. Vacuum can not change the temperature instead of refrigeration, it must be combined with refrigeration to achieve the effect of prolonging storage.
