Finding the Best Food Vacuum Sealer
Vacuum sealers are quite common in restaurants, food manufacturers, and even in households. These machines are used to protect and preserve food products. They are very popular packaging food because of their ability to extend the shelf life of the food. By removing the air around the food, it eliminates all sorts of bacteria and pathogens that thrive in oxygen, which may spoil the food. A vacuum sealer, however, do not eliminate spoilage, but it will delay the process.
Meat and seafood products are the most common food products that are vacuum-sealed especially when the food will be placed in a freezer. Freezing the food can also help extend its shelf life. The sealer bag stops bacterial contamination and at the same time, it prevents freezer burn. Other food that are vacuum sealed are vegetables.
Choosing the Sealer
If you are in a hunt for the best vacuum sealer, you need to consider a few things. You should also be aware that there are two types of vacuum sealers on the market: the external and the chamber vacuum sealers. Both of these machines may have similar purpose, but they are differ entirely when it comes to the method of packaging.
If you need the sealer for high-volume packaging, choose a chamber sealer since external sealers are ideal for low-volume production. This is because chamber sealers operate at a much higher speed than external sealers. Chamber sealers are also used to replace the oxygen in the bags with nitrogen, as in the case of potato chips. This key factor in packaging is helpful in extending the shelf life of the food.
An external sealer simply removes air inside the bag, and then seals it, while a chamber sealer vacuums air within the chamber and the bag as well, then seals the bag. Then, the machine brings back the normal atmosphere of the vacuumed chamber. It seals the bag inside the vacuum, making the food product 99.99% air-free.
You may allow adjust the amount of air to remove from the bag using a chamber sealer or a high-end external sealer, which ideal for delicate food items. When using a chamber sealer to pack delicate food products, it is usually fitted with an inert gas kit. The machine removes 99.99% air inside the chamber, and then supplement a portion of the inert gas, usually nitrogen, to the chamber before the bag is sealed. With this process, the food is not tightly sealed with the bag, but the air inside will not allow organisms to thrive.
If You Choose a Chamber Sealer
If you feel that the chamber vacuum sealer is best for you and your production, determine the maximum capacity of the machine. In other words, identify the maximum size of the product that can be packaged in the chamber because chamber sealers come in different sizes. You may want to purchase the largest size possible because, you’ll never know, you may have to pack larger products in the future. If you will use a large chamber sealer, you can pack multiple items at one time, increasing speed and productivity.
