Vacuum sealers have recently been around for some time, but there are many things may well not know about them. Firstly, no vacuum cleaners are involved, however , a whole lot of suction is. Vacuum cleaner sealers are being used to protect and preserve food. There are a few things you need to know about vacuum sealers before making a purchase, starting with the various types of sealers available.
Vacuum sealers are suitable for packaging a multitude of foods. You see food in the grocery store packaged this way all the time, whether you recognize it or not. Beef jerky, salmon steaks, spud chips and dried fresh fruit are only a few of the items you may find.
Vacuum sealers essentially remove or replace natural air. In the case of beef jerky, 99. 99 percent of the air is removed, which makes it near impossible for bacteria to cultivate. Along with potato chips, natural air (which includes life offering oxygen) is removed and replaced with an inert gas, such as nitrogen. Because potato chips are so fragile, removing 99. 9 percent of the air would damage the product.
There are two main types of vacuum sealers used for packaging Foodsaver. These are external and chamber vacuum sealers. Both sealers are being used to remove air, but have different purposes and are being used for a range of different products. Before making a vacuum sealer purchase, make certain you are getting the right kind.
External vacuum sealers are similar to the models seen on TV or sold in a department store for home use. This does not mean all exterior vacuum sealers are for home use. Some exterior vacuum sealers are created for commercial packaging use.
With an external vacuum sealer bags, place your product in a bag and place the open end into the sealer. The sealer will remove the air and seal the open end, avoiding air from re-entering the bag. External vacuum sealers cannot be used with fragile products such as spud chips due to the fact they cannot replace the air with an inert gas.
Chamber vacuum sealers are the most frequent machines used for commercial packaging. Step vacuum sealers still use bags, like the exterior models, but the product packaging process is much different.
Using a chamber sealer, the product is located in a bag, after which the whole bag is positioned in the chamber. Once ready, the chamber cover is pulled down. The machine then removes 99. 9 percent of the air within the chamber and seals the open conclusion of the bag.
Typically the atmosphere within the camber is then returned again to normal. The covered bag is now vacuum cleaner packaged and ready for sale or storage. Part of the process, if needed, can involve eliminating the air and changing it with an inert gas. The amount of air taken out of the step can even be adjusted as needed.
