With the acceleration of the pace of life, people’s demand for food preservation is also increasing, and vacuum packaging machines have become indispensable kitchen appliances in modern households and enterprises. However, there are many brands and models of vacuum packaging machines on the market, and prices range from a few hundred yuan to tens of thousands of yuan. How to identify and choose a suitable vacuum packaging machine?

• Classification and characteristics of vacuum packaging machines

1. Classification by degree of automation
Vacuum Sealer can be divided into manual, semi-automatic, and fully automatic types. The manual vacuum packaging machine is easy to operate and cost-effective, but has low efficiency, making it suitable for personal and small batch production use; The semi-automatic vacuum packaging machine has a high degree of automation and improved work efficiency, making it suitable for small and medium-sized batch production; The fully automatic vacuum packaging machine has a higher degree of automation, high work efficiency, and is suitable for large-scale production.

• Classification by sealing form

Vacuum packaging machines can be divided into hot sealing and cold sealing types. The heat sealing vacuum sealing machine adopts a heat sealing process, which is firmly sealed and suitable for packaging materials of various thicknesses; The cold sealing vacuum packaging machine adopts a cold sealing process, which is aesthetically pleasing and suitable for thinner packaging materials.

2、 Key points for quality identification of vacuum packaging machines

• Material

The material of vacuum packaging machines directly affects their service life and performance. The manufacturing material of high-quality vacuum packaging machines is usually stainless steel, which has good corrosion resistance, wear resistance, and oxidation resistance. Consumers can observe whether the body is made of stainless steel material and whether the connections between various components are tight and seamless when making a purchase.

• Electronic components

The quality of electronic components in vacuum packaging machines is directly related to their performance stability and safety. The electronic components of high-quality vacuum packaging machines usually use internationally renowned brands such as Siemens, Schneider, etc. These components have stable performance and low failure rates. Consumers can inquire about the brand and origin of electronic components from the manufacturer or refer to the product manual when making a purchase.

• Vacuum pump

Vacuum pump is the core component of vacuum packaging machine, and its performance directly affects the effectiveness of vacuum packaging. High quality vacuum packaging machines typically use high-performance, low-noise vacuum pumps. Consumers can observe whether the appearance of the vacuum pump is exquisite and whether the sound of the vacuum pump during operation is normal when making a purchase.

• Sealer

The quality of the sealer directly affects the aesthetics and firmness of vacuum packaging. The sealing device of high-quality vacuum packaging machines is usually made of high-temperature and wear-resistant materials, such as ceramics, tungsten carbide, etc. When consumers make a purchase, they can observe whether the appearance of the sealer is smooth, shiny, and whether the sealer moves smoothly during operation.

• After sales service

The after-sales service of vacuum packaging machines is also an important factor in measuring their quality. Manufacturers of high-quality vacuum packaging machines usually provide comprehensive after-sales service, such as free maintenance and technical support during the warranty period. The vacuum packaging machine purchased from our company will provide one year of after-sales support service.
