An external vacuum sealer is an appliance that attaches to a specific type of bag, to remove the air from that bag. The key to food preservation by vacuum is to remove all extra air, which prohibits the growth and spread of bacteria. An external sealer attaches to the special type of bag by clamping onto it. Once it sucks all of the air out of it, the machine can seal the bag, or prompt the user to seal the bag.
The sealed bag is then 99.9% air-free and can be stored for quite a long time in either your refrigerator or freezer. Compared to conventional food storage techniques of using zip-top seal bags, you will be amazed at how much more effective it is to use a vacuum sealed bag. An external vacuum sealer is definately the easiest way to get started with vacuum sealing your leftovers.
An external vacuum sealer is the most common, and less expensive way of performing food vacuuming. An external sealer is identified by the way it clamps onto a type of bag, and then sucks the air out. Compare this to a chamber vacuum sealer, where the food is placed inside the sealer appliance itself. If you are new to vacuum storage and looking to get started, then an external vacuum sealer is usually considered a good first purchase since it is less expensive and relatively easy to use.
