What is vacuuming? Why is vacuuming necessary?

12/03/y 11:25:33

Vacuuming is considered an effective method for packaging and preserving food, especially agricultural products and fresh foods. Using a vacuum machine can help prolong the storage time and maintain the quality of the product, limiting the growth of bacteria and mold. It is often trusted by households to manufacturing enterprises looking for ways to better protect their products.

So how does a vacuum cleaner work and why should you use one? The benefits it brings will definitely make you consider investing in one right away. Let's find out in the article below!

What is a vacuum cleaner used for?

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

Under normal conditions, oxidation reactions occur with organic substances in the product, causing them to spoil quickly. 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 room temperature. Similarly, fruits such as strawberries or tomatoes are also very susceptible to spoilage in a short time. 

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

Vacuum cleaner classification

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

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

- Industrial vacuum machine: Designed for industrial zones 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 from the packaging, the product is protected from oxidation and bacteria, helping to extend its shelf life and ensure quality. 

Not only stopping at food, the vacuum packaging method is also applied to protect other types of goods such as documents, electronic equipment, and industrial products. Removing air helps minimize the impact of the environment, ensuring that the product is not damaged by mold or corrosion.

What are the advantages of vacuum packaging method?

  • The vacuum packaging method utilizes specialized machines to remove oxygen from the packaging, helping to prevent oxidation and fermentation— the main causes of food spoilage.

  • Thanks to the vacuum environment, food products are preserved for a longer period, extending their shelf life by 3 to 5 times compared to conventional methods. This technique also slows bacterial growth, prevents mold and insects, and helps maintain the food’s freshness.

  • Beyond preservation, vacuum packaging helps retain the natural moisture and original color of food while protecting it from freezer burn. For dry goods, this method also ensures long-term stability.

  • Additionally, removing air helps save storage space, making transportation and usage more convenient. That’s why vacuum-packed food is commonly found in supermarkets, with its color and flavor preserved just like when it was first packaged.

The scent of new wood in a newly handed-over apartment: How to measure and address formaldehyde (HCHO) levels before moving in
14/11/y 10:28:19

Many people refer to the pungent, acrid odor that emerges when opening a new cabinet as the "smell of new wood," assuming it will simply dissipate after a few days. In reality, however, what is being released could well be formaldehyde—a substance originating from the adhesives used in the pressed-wood panels—and our sense of smell is not a reliable enough gauge to determine the concentration levels present

Guide to Selecting a TCLP Toxicity Characteristic Leaching Procedure Shaker Configuration in Compliance with QCVN 07:2025/BNNMT and TCVN 9239:2012
13/11/y 17:23:39

Regulation QCVN 07:2025/BNNMT (replacing QCVN 07:2009/BTNMT and QCVN 50:2013/BTNMT) specifies hazardous waste and sludge thresholds based on leachate concentrations. To ensure that analytical results for heavy metals and organic compounds are accepted during ISO/IEC 17025 or VIMCERTS assessments, laboratories must comply with the Toxicity Characteristic Leaching Procedure (TCLP) specified in TCVN 9239:2012, which is equivalent to US EPA Method 1311

Checking the Temperature of Paint and Coating Surfaces After Curing Using an Infrared Thermometer

An infrared thermometer allows surface temperature measurement without direct contact, making it suitable for products coming out of curing ovens or surfaces that are difficult to access. However, to ensure reliable results for production quality control, it is important to understand the measurement principle and the factors that affect measurements on painted and coated surfaces.

Crowded Gyms and Yoga Studios: How to Manage Air Quality to Retain Members
13/11/y 15:07:40

Around 6 or 7 in the evening, the gym becomes packed; the music drowns out the sound of heavy breathing, and the air conditioning runs at full blast behind closed doors. At first glance, everything seems fine: the room is cool, the lights are bright, and the equipment is state-of-the-art. Yet, after just a few sessions, regular members begin to feel a heavy-headedness and find themselves running out of breath more quickly eventually, they simply stop renewing their memberships. No one complains about the personal trainers or the exercise machines. The very thing that makes them feel stifled and drives them away is something entirely invisible: the air inside the room
