Vacuum packaging machine: the working principle and the purchase of the main points can not be ignored

In modern life and production, vacuum packaging machine plays an increasingly important role. It is widely used in food, electronics, medical and many other industries, providing a reliable guarantee for the preservation of freshness, moisture, oxidation and other products. So, how does the vacuum packaging machine actually work? In the purchase and what points we can not ignore? Let us come together to understand in depth.

Working principle of vacuum packaging machine
The working principle of the vacuum packaging machine is mainly based on the vacuum pump to create a vacuum environment. When the machine is started, the vacuum pump begins to run, through the suction pipe will be pumped out of the air inside the packaging container. As the air is continuously pumped out, the air pressure inside the packaging container is gradually reduced to form a certain vacuum level. After reaching the preset vacuum level, the sealing device will quickly heat and pressurise the packaging material to make it fit tightly on the surface of the product, thus completing the sealing package. This process may seem simple, but it requires the precise cooperation of various components to ensure the quality and effect of packaging.

Purchase of vacuum packaging machine can not be ignored points

1. Material and quality
* Body material
Machine body material is directly related to its durability and hygiene. High-quality vacuum packaging machine is usually made of stainless steel, such as 304 stainless steel has good corrosion resistance, can be used for a long time to maintain stability, and easy to clean and maintain, in line with the hygiene standards of food and industrial production. For example, KUNBA vacuum packaging machines are made of 304 high-quality stainless steel with a material thickness of 3.2mm, which guarantees the robustness of the machine.
* Quality of key components
The vacuum pump is one of the core components of the vacuum packaging machine, and its quality determines the vacuum degree and pumping speed of the machine. High-quality vacuum pump can extract air quickly and efficiently to achieve high vacuum packaging, so as to better extend the shelf life of products. In addition, the quality of the sealing device should not be ignored, it needs to ensure the sealing and firmness of the seal, to prevent air from re-entering the package.

2. Packaging performance
* Vacuum degree
High vacuum degree is one of the important indexes to measure the performance of vacuum packaging machine. Only a machine with high vacuum degree can effectively remove the air inside the package, inhibit the growth and reproduction of microorganisms, and provide good freshness and protection for the product. When purchasing, pay attention to the value of vacuum degree that the machine can achieve and its stability.
* Packaging speed
For manufacturers, packaging speed directly affects production efficiency. Fast vacuum packaging speed can meet the needs of mass production and reduce the cost of production time. Therefore, when choosing a vacuum packaging machine, according to their own production scale and demand, choose the appropriate packaging speed of the machine.
* Versatility
A good vacuum packaging machine should have strong versatility, can adapt to different sizes, shapes and types of product packaging. This can provide more flexibility for the enterprise, reduce the cost and trouble due to changes in product specifications and the need to replace the equipment.

3. Appearance and structure
* Appearance design
Although the appearance is not the core performance indicators of the vacuum packaging machine, but an aesthetically pleasing appearance design can not only enhance the overall aesthetics of the working environment, but may also reflect the manufacturer's degree of intentionality in product design and manufacturing process. At the same time, a reasonable appearance design should also take into account the convenience of operation and ergonomics, so that the operator is more comfortable and convenient in the process of use.
* Compact structure
In some production places with limited space, the compactness of the machine is particularly important. Compact structure design can save floor space, convenient equipment placement and layout. In addition, the reasonable structure of the vacuum packaging machine in the maintenance and maintenance will be more convenient, can reduce maintenance costs and time.

4. Convenience of operation
* Control system
Advanced control systems can make the operation of the vacuum packaging machine more simple and intuitive. For example, using the touch screen operator interface, the operator can easily set the packaging parameters, monitor the packaging process, and can quickly adjust and troubleshooting. The simple and easy-to-understand operation process can greatly reduce the operator's training costs and work intensity, and improve production efficiency.
* Safety performance
Safety is the production process must be the primary consideration. High-quality vacuum packaging machine should have perfect safety protection devices, such as overload protection, leakage protection, emergency stop button, etc., in order to prevent accidents in the process of operation, to protect the personal safety of the operator and the normal operation of the equipment.

5. Brand and after-sales service
* Brand reputation
Choose a well-known brand of vacuum packaging machine can often get more protection in terms of quality and after-sales service. Famous brands usually have rich production experience and technical accumulation, the quality of the product control is more strict, can provide more stable and reliable products. At the same time, the brand's reputation is also an important embodiment of its product quality and service level, you can check the user evaluation, industry reputation and other ways to understand the brand's reputation.
* After-sales service
Perfect after-sales service is one of the important guarantees for the purchase of vacuum packaging machines. In the process of use, the machine will inevitably appear some faults or need to carry out maintenance. Good after-sales service team can respond to customer needs in a timely manner, provide professional technical support, maintenance services and parts supply, to ensure the normal operation of the machine, reduce production delays and losses caused by equipment failure.
