1. Vacuum Pack Machine
A vacuum pack machine is used to package items, especially perishable food items such as meat, fish and
other foods within an envelope of impervious plastic by extracting as much of the oxygen or air from the inside
of the package as possible. The extraction of the air from inside the food minimizes oxidation of the food and
helps to prevent spoilage and preserve the food for a long period of time. Food items that are packaged using
a vacuum pack machine maintain their freshness and naturalness for much longer than foods packed using
other means. A vacuum pack machine is also made use of in order to reduce the bulk of non-food items for
increased storage efficiency.
A vacuum pack machine is extensively used by the meat industry above all. This technology and equipment
has made it possible for meat to be packaged and stored fresh for a long duration of time that surpasses
other methods, which makes it possible to ship meat over longer distances and trade with markets that would
otherwise be impossible to reach. Other food items are also kept fresh by using a vacuum pack machine
such as coffee, seafood and many dried food items as well. A vacuum pack machine for household use lets
individuals vacuum package their own food items.
A vacuum pack machine encloses and seals the food in plastic bags by removing the oxygen or air from the
bag. As mentioned earlier, the extraction of air from the bag prevents oxidation, which is the reaction caused
by oxygen with the food. Oxidation is an essential element in the process of spoilage. Food items that do not
rot and go bad but merely become stale can also gain from a vacuum pack machine, as the lack of air stops
the food from absorbing moisture.
A vacuum pack machine also minimizes the growth of bacteria. Since food items are packed in controlled,
hygienic environments, bacteria is kept away from the food, which prevents several harmful bacteria from
breaking down the food. The action of bacteria on food items is another main component of food spoilage.
Yeast and mold, which need oxygen to survive and breed is also prevented by using a vacuum pack machine.
Using a vacuum pack machine to package frozen food items also helps to reduce the occurrence of freezer
burn. Freezer burn can take place when moisture is drawn from the food and the food becomes oxidized and
dehydrated. Vacuum packed frozen food items prevent freezer burns due to the absence of air in the package.
