What is a vacuum cleaner used for?

Vacuum packaging machines are used in packaging and preserving food by removing air inside the packaging. 

Under normal conditions, oxidation reactions occur with organic substances in products, causing them to quickly deteriorate. In particular, fresh foods such as pork, chicken, beef, or seafood such as shrimp, crab, and fish can usually only be preserved for 1-3 days at normal temperature. Similarly, fruits such as strawberries or tomatoes are also easily spoiled in a short time.

To meet the need for more effective food preservation, vacuum sealers were born as a modern and convenient solution. This device not only helps extend shelf life but also preserves the quality and freshness of the product.

Classification of vacuum machines

Vacuum packaging machines are divided into two main types, meeting different needs:

- Mini vacuum cleaner (family): Suitable for households and small businesses, with compact design and easy to use.  

- Industrial vacuum machine: Designed for industrial parks or large manufacturing enterprises, meeting packaging requirements with high productivity.  

Why is this method necessary? 

The reason is because this is an effective preservation method, often applied to food, pharmaceuticals, medical equipment, and seafood. By removing air inside the packaging, the product is protected from oxidation and bacteria, helping to prolong shelf life and ensure quality.  

Not just stopping at food, vacuum packaging is also used to protect other types of goods such as papers, electronic equipment, and industrial products. Removing air helps minimize environmental impact, ensuring the product is not damaged by mold or corrosion.. 

What are the advantages of the vacuum packaging method?

- Vacuum packaging method uses specialized machines to remove oxygen inside the packaging, helping to prevent oxidation and fermentation - the main cause of food spoilage.  

- Thanks to the vacuum environment, food products are preserved longer, extending their lifespan 3-5 times compared to normal. At the same time, this method slows down the growth of bacteria, prevents mold and insects, helping food always retain its freshness..  

- Not only stopping at preservation, vacuum packaging also helps maintain the natural moisture, original color of the food, and protects the product from spoilage due to freezing. For items that require dry storage, this method also ensures long-term stability.  

- In addition, removing air also helps save storage space, making it more convenient to transport and use. This is why you often see vacuum-packaged foods appearing commonly in supermarkets, with the color and flavor remaining the same.
