Grocery shops, food makers and numerous people use vacuum sealers to safeguard and preserve food. The truth is, vacuum sealers will be the most typically used piece of equipment for food packaging. The purpose they're so typically used is because vacuum sealers drastically extend the shelf life of food. This really is accomplished by removing life-giving air that numerous life types use to flourish. While this doesn't absolutely eliminate spoilage, it aids a whole lot.

One of the most common food products to become vacuum-sealed are meats, especially for use inside a freezer. Vacuum sealer bags not simply lower bacterial contamination, but also protect against freezer burn. You'll normally see this with halibut and salmon fish fillets & steaks. Vegetables are also commonly 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 really is mainly because 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 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. Due to the fact 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 become adjusted. That 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 of your 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 types of bacteria.
Before choosing a chamber sealer, it is highly recommended to determine the maximum size of product to become packaged. This can be mainly 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.
