What is Table Top Vacuum Packing Machine?

Table Top Vacuum Packing Machine is a small packaging equipment that plays an important role in many fields. It is popular because of its small size and can be placed on the desktop.

1. Structural composition

Vacuum chamber

Usually made of high-strength transparent materials such as acrylic or tempered glass. On the one hand, this design makes it easy for users to clearly observe the internal situation during the packaging process and keep track of the packaging progress at any time; on the other hand, the high-strength material can ensure that the vacuum chamber will not break when subjected to a certain pressure difference, ensuring the safety of operation. The size of the vacuum chamber will vary depending on the different models of Table Top Vacuum Packing Machine to meet the packaging needs of items of different sizes.
The vacuum chamber is usually also equipped with a sealing strip to ensure that a good sealing environment can be formed during the vacuuming and sealing process to prevent air leakage, thereby ensuring the vacuum degree of the packaging.

Vacuum pump

As the core component of Table Top Vacuum Packing Machine, the performance of the vacuum pump directly determines the effect and speed of packaging. Common types of vacuum pumps include rotary vane vacuum pumps, vortex vacuum pumps, etc. The vane vacuum pump has the characteristics of simple structure and fast pumping speed, and is suitable for most small tabletop vacuum packaging machines. The vortex vacuum pump has the advantages of low noise, smooth operation and long life, and is used in some high-end models of Table Top Vacuum Packing Machine.
The power of the vacuum pump will also affect its pumping capacity. A vacuum pump with a higher power can achieve a higher vacuum degree in a shorter time, which is suitable for occasions with high packaging speed requirements. For the packaging of some small items, a vacuum pump with a lower power can also meet the needs and is more energy-efficient.

Sealing device

After the vacuum extraction is completed, the sealing device heat-seals the packaging material to ensure the sealing of the packaging. The sealing device usually uses heating strips or high-frequency sealing technology. Heating strip sealing is to heat the metal strips to melt and bond the packaging materials together at high temperature. This sealing method is simple and reliable, with low cost, and is suitable for most plastic packaging materials. High-frequency sealing uses high-frequency electromagnetic fields to vibrate the molecules of the packaging material to generate heat, thereby achieving sealing. High-frequency sealing has a better sealing effect and is suitable for occasions with high sealing requirements, such as food, medicine and other industries.
The temperature and time of the sealing device can be adjusted according to different packaging materials and items. Too high temperature and too long sealing time may cause the packaging material to burn or deform, affecting the packaging quality; while too low temperature and too short sealing time may cause the sealing to be loose and leak.

Control system

It is used to control the various operations of the Table Top Vacuum Packing Machine, including the setting and adjustment of parameters such as vacuum extraction time, sealing temperature, and sealing time. The control system is usually controlled by a microcomputer, which has the advantages of simple and convenient operation, high precision, and good stability. Users can easily set the required parameters through the buttons or touch screen on the control panel, and monitor various data in the packaging process in real time.
Some high-end Table Top Vacuum Packing Machines are also equipped with intelligent control systems, which can automatically adjust parameters according to different items and packaging requirements to achieve intelligent packaging. In addition, the control system also has fault diagnosis and alarm functions. When the equipment fails, it can issue an alarm in time to remind the user to repair it.

2. Working principle

Put the items to be packaged into the vacuum chamber, cover the lid, and start the Table Top Vacuum Packing Machine. The vacuum pump starts working, connected to the vacuum chamber through a pipeline, extracts the air in the vacuum chamber, and gradually reduces the pressure in the vacuum chamber. During the vacuuming process, air is extracted from around the packaged items, reducing the presence of oxygen, thereby inhibiting the growth of microorganisms and the occurrence of oxidation reactions, and extending the shelf life of the items.
When the vacuum degree reaches the set value, the sealing device starts working. The heating bar or high-frequency electromagnetic field causes the packaging material to melt and bond together at high temperature to seal the package. After the sealing is completed, the Table Top Vacuum Packing Machine automatically stops working, opens the lid, and takes out the packaged items. The entire packaging process is fast and efficient, and can complete the vacuum packaging of items in a short time.

3. Application field

Food industry

It can be used to package meat, seafood, cooked food, fruits, vegetables and other foods. For meat and seafood, vacuum packaging can effectively prevent oxidation and deterioration, and maintain its freshness and taste. After cooked food is vacuum packed, the shelf life can be extended, which is convenient for storage and transportation. Fruits and vegetables can reduce water evaporation, delay aging, and maintain their nutritional value under vacuum packaging.
Some food processing plants and supermarkets also use Table Top Vacuum Packing Machine to package bulk food to improve the grade and hygiene level of the products. In addition, vacuum packaging can also be used for frozen storage of food to prevent frostbite and oxidation during the freezing process.

Pharmaceutical industry

Used to package medicines, medical devices, etc. Under vacuum packaging, medicines can be prevented from moisture, oxidation, and deterioration to ensure the quality and safety of medicines. After vacuum packaging, medical devices can avoid contamination by dust, bacteria, etc., which is convenient for storage and transportation.
Some hospitals and clinics also use Table Top Vacuum Packing Machine to package some special medicines and medical devices, such as surgical instruments, implants, etc., to ensure that they are sterile before use.

Electronic products industry

Vacuum packaging of electronic products can prevent electronic products from moisture, oxidation, and corrosion. During the production and transportation of electronic products, vacuum packaging can effectively protect electronic products from the influence of the external environment and extend the service life of electronic products.
Some high-end electronic products, such as mobile phones and tablets, will also be vacuum packaged when leaving the factory to improve the grade and brand image of the products.

Precision Instrument Industry

Used to pack precision instruments, optical instruments, etc. Precision instruments and optical instruments have very high requirements for the environment. Any dust, moisture, etc. may affect their accuracy and performance. Vacuum packaging can provide a dry and clean environment for these instruments to prevent the instruments from being affected by external factors.
Some laboratories and scientific research institutions also use Table Top Vacuum Packing Machine to pack some precious experimental instruments and samples to ensure their safety during storage and transportation.
