General Safety Rules for Food
Scientifically speaking, following the safety rules can make food safer and get the more
ideal effect for vacuum preservation.
1. If perishable food is heated or defrosted, it should be eaten as soon as possible.
2. Once a vacuum-sealed bag is opened, you can follow the same instruction to
vacuum-seal it again.
3. The best way to unfreeze a frozen bag is to put it in cold storage and let it slowly
unfreeze, instead of sinking it in hot water or heat it by e.g.., microwave.
4. If seasoned food is vacuum-sealed or preserved by other methods and has been
kept in a indoor temperature for a few hours, do not eat it as it could potentially
be toxic.
5. To quickly freeze a bag of food, place it evently flat to the freezer.
For Bulk Food Vacuum Packaging,
Recommendations are as follows:
1. Before vacuum packing, wash hands and other cutting tools.
2. For perishable food, it is best to refrigerate immediately after vacuum sealing.
3. Vacuum-sealing dried goods, such as beans and grain, will postpone their expiration
dates. But if kept in indoor temperature or dark places, they are likely to be oxidized
or sprout.
4. When vacuum-sealed and kept in cold storage, vegetable, such as cabbage and broccoli,
will let out some gases. Make sure they are wrapped and have been kept in cold storage
before you try to vacuum seal them.
Cleaning and Maintenance of the Vacuum Sealer
1. Unplug the machine before cleaning it.
2. Do not sink the machine or its electric wire in water or other liquid for cleaning.
3. After use, wait for the machine to completely cool down, then use a wet sponge or
cloth to clean the vacuum chamber and surface.
4. Do not use a brush to scrub the machine, otherwise it will leave scratches.
5. Use a tissue or cloth to clean food residue or liquid inside the vacuum chamber
(Before you turn on the machine, please make sure the interior and exterior are all
completely dried).
6. After use, please put the support card between the upper and lower shell of the
machine, so as not to affect the use of the sealing sponge under pressure deformation.
Cleaning the Preservation Bag
1. A used preservation bag can be cleaned by warm water. An appropriate amount of
edible detergent can be added to the water. Wash clean with fresh water and dry it
before re-use. Discarding it after three times of re-use is recommended.
