Vacuum Packing Machine: How It Works And Its Benefits

The rapid growth of the food industry is highly influenced by technological innovations. Leading names in the food industry are each day researching packing technologies and adapting to the latest innovations. One such innovation in the food packing industry is the vacuum packing machine. In today’s modern society, this machine is indispensable and retains original taste and flavor. These machines can be used in kitchens, hotels, and for commercial purposes.

Working of Vacuum Packing Machine

Vacuum packing is a packaging method that eliminates air from the package prior to sealing. It generally contains two parts: a hermetically sealed chamber with a pump that uses rotating blades which remove all the air, and thermal strips which are used to seal a vacuum pouch within the machine. The sealing cycle takes approximately 20 to 45 seconds to complete, depending on the power and size of the pump in the machine. The duration of the process depends on the volume of air to be expelled. We can increase the efficiency of the vacuum packing process by embedding as many vacuum pouches as possible on the thermal strips while maintaining the sealing process. We can also stack up pouches depending on the type of pouches used. However, there are two types of machines.

Mechanical squeeze type –

In this type, after the food packet is filled, the air is primarily evacuated from the bag by elastic items like a sponge on both sides, and the bag is then zipped and sealed.

In these packing machines, the exhaust valve is inserted into the mouth of the bag, and vacuuming the vacuum by opening the exhaust valve. Once the predetermined vacuum degree is achieved it is sealed.

Benefits of Vacuum Packing machine

Increases Shelf life – Shelf life is the time span in that food can be stored and is consumable. According to studies, vacuum packaging can increase product shelf life by 50%-400%. The supreme factors to enhance the shelf life of packaged food are the environment and the standard of vacuum packaging. This could include the addition of inert gas or the reduction of oxygen to optimal levels. Vacuum packaging is also a popular choice for many products going into long-term freezer storage. For example, meat normally preserved for two days can be preserved in a refrigerated environment for up to six days. The use of the right vacuum bags can significantly reduce freezer burn.
No chemicals are used – Individuals and businesses can safely store fresh foods without the use of chemicals if they have a vacuum packing machine. Anyone who wants to reduce the number of chemicals in their diet will find it to be beneficial. The amount of preservatives in today’s food is a bit surprising. However, vacuumed food products are a blessing from harmful chemicals.
Visibility of food – The appearance of a product is broadly a core driver in marketing strategy for any business. Retailers of food want their products to be appealing to consumers. Customers prefer to choose packed foods that are visible. Food can be showcased exquisitely using vacuum packs. They make it feasible to keep food items in a hygienic and secure refrigerator whilst perfectly visible.
Multiple Packing Options – There are several packaging options available for vacuum sealing materials. To seal products, customers can purchase rolls of film or bags. Reclosable zippers, easy-open tear notches, foil lining, channeling, and a variety of other features are available on bags.
Optimize storage and reduce waste – Food service processes require enough storage space to keep high quantities of ingredients. As a result, vacuum packaging has the potential to make the best use of storage space since all types of foods can be efficiently stacked together, rather than using containers that take up a lot of space. Overall, vacuum packaging machines allow foods to be stored for longer periods, resulting in better portion control and reduced food waste.
Vital for sous-vide cooking – With sous-vide cooking, a vacuum seal-type bag works better. Whatever you want to cook sous-vide, you must place the food in a vacuum-sealed bag. This reduces the chance of food packaging rupturing, expanding, or spoiling during the sous-vide cooking process. Most importantly, the vacuum-sealed bag works more effectively than conventional zipper bags since the air inside the bag may expand and float to the surface during the cooking process, causing uneven cooking.

Conclusion

When a product is vacuum packed, minimal oxygen surrounds it, which prevents the growth of aerobic bacteria and fungi. Consequently, this prolongs the preservation of packaged food via a healthy process. For this machine, an initial investment is required but the benefits provide a good return on investment. Being a duo of financially and practically valuable machines, it is highly demanded by the food industry.
