What to Look For in a Vacuum Sealer
Grocery retailers, food producers and quite a few people use vacuum sealers to guard and preserve food. In reality, vacuum sealers are the most commonly used piece of equipment for food packaging. The explanation they may be so commonly used is for the reason that vacuum sealers considerably extend the shelf life of food. This can be carried out by removing life-giving air that a lot of life types use to flourish. Whilst this does not totally do away with spoilage, it helps lots.

One with the most common food products to be vacuum-sealed are meats, specifically for use within a freezer. Vacuum sealer bags not just lower bacterial contamination, but also stop freezer burn. You can generally see this with halibut and salmon fish fillets & steaks. Vegetables are also usually vacuum-sealed and frozen. The cold temperature further extends the shelf life of food.
When a store or manufacturer, whether big or small, is in the market for a vacuum sealer, there are a few things to keep in mind. There are two major types of vacuum sealers on the market. These are external and chamber vacuum sealers.
Although useful for low-volume production, external vacuum sealers are not an ideal choice for high-volume packaging. This can be for the reason that external sealers do not operate, in most situations, at as high a speed as a chamber vacuum sealer. They also cannot be used to replace natural oxygen-based atmosphere in the bags with inert gas such as nitrogen. This really is a key factor in packaging products such as potato chips.
Chamber sealers use an entirely different method of packaging versus external vacuum sealers. An external vacuum sealer removes air from within the bag and seals it. A chamber sealer removes air from the entire chamber, including the bag, seals the bag and then returns the vacuumed chamber to a normal atmosphere. Mainly because the bag is sealed within the vacuum, the product is 99.99 percent air free once the process is completed.
Chamber sealers and some high-end external sealers will allow the amount of removed air to be adjusted. This really is ideal when packaging delicate food products. When packaging delicate food, a chamber sealer (fitted with an inert gas kit) will remove 99.99 percent from the air within the chamber and then add a set percentage of inert gas (such as nitrogen) back into the chamber before sealing the bag. This way the bag isn't tight against the food, but the air will not sustain most forms of bacteria.
Before choosing a chamber sealer, it is highly recommended to determine the maximum size of product to become packaged. This really is because chamber vacuum sealers are available in different sizes. It is financially prohibitive to purchase a machine, only to find out a year later than larger products need to become packaged. A larger chamber can also allow the user to package multiple items at once, thus increasing packaging speeds.
