The single-chamber vacuum packaging machine is a mechanical equipment suitable for medium-sized vacuum inflation packaging. It is mainly used to automatically seal the packaging bag after the packaging bag is evacuated to a low vacuum, thereby reducing the oxygen content in the bag, inhibiting the growth and reproduction of bacteria and other microorganisms, extending the shelf life of the product, and preventing mildew, corruption and moisture.
1. Equipment Overview
The single-chamber vacuum packaging machine is suitable for a variety of industries, including vacuum packaging in the fields of food, condiments, bean products, medicines, grains, electronic products, precision instruments, etc. It uses plastic composite film or plastic aluminum foil composite film as packaging material, and can vacuum package various forms of goods such as solids, liquids, powders, pastes, etc.
2. Working Principle
Vacuum treatment: Put the packaging bag containing the items into the vacuum chamber, close the cover, and the vacuum pump starts to evacuate the air, so that the packaging bag and the vacuum chamber reach a low vacuum state at the same time.
Sealing operation: After reaching the preset vacuum degree, the heat sealing device starts to heat and seal the packaging bag mouth.
Inflating function (optional): Some models support the filling of inert gases such as nitrogen before sealing to enhance the anti-corrosion and moisture-proof effects.
Cooling and output: After the sealing is completed, the vacuum chamber is connected to the atmosphere, the cover is automatically lifted, the packaged product is taken out, and the next cycle begins.
3. Main features
Fully transparent cover design: Made of plexiglass, it is easy to observe the packaging process.
Multifunctional integration: It has functions such as vacuuming, sealing, and printing, and can achieve the best packaging effect by adjusting parameters such as vacuum degree, heat sealing temperature, and heat sealing time.
Printing device: Equipped with an easy-to-change printing device, it can print product-related information such as shelf life, factory date or number while sealing.
Advanced design and stable performance: Reasonable structure and complete functions, suitable for small and medium-sized production needs.

Pharmaceutical industry: medicines, biological products, etc.
Chemical industry: chemicals, electronic components, precision instruments, etc.
Other industries: vacuum compression packaging of fabrics, cotton and wool products, saving logistics costs.
6. Advantage analysis
Extending shelf life: effectively reducing the oxygen content in the bag, inhibiting the reproduction of microorganisms, and preventing product oxidation and mildew.
Improve product quality: prevent moisture and corruption, and maintain the freshness and taste of the product.
Easy operation: high degree of automation, only one person is needed to operate, reducing labor costs.
Strong adaptability: can package various forms of goods to meet the packaging needs of different industries.
7. Purchase suggestions
Choose the model according to production needs: choose the appropriate equipment according to packaging speed, bag type, material characteristics, etc.
Pay attention to the quality of the vacuum pump: the vacuum pump is a core component and directly affects the vacuum efficiency. It is recommended to choose a well-known brand.
Consider the stability of the equipment: choose equipment with reasonable structure and excellent materials to ensure long-term stable operation.
Pay attention to after-sales service: choose manufacturers that provide timely technical support and spare parts supply.
8. Maintenance and care
Regular cleaning: clean the vacuum chamber, heat seal strips and other parts to prevent residues from affecting equipment performance.
Check the vacuum pump: regularly replace the vacuum pump oil to ensure vacuum efficiency.
Lubrication and maintenance: lubricate the transmission parts to reduce wear.
Timely maintenance: contact professional maintenance personnel in time when the equipment fails to avoid self-disassembly.
