The double-chamber vacuum packaging machine is an efficient vacuum packaging equipment. It realizes continuous packaging through two alternately working vacuum chambers. It is suitable for vacuum and gas-filled packaging of various materials and has the functions of extending shelf life, moisture-proof and anti-oxidation.
1. Equipment Overview
The double-chamber vacuum packaging machine is equipped with two vacuum chambers, which realize continuous packaging through alternating operation. The equipment is made of stainless steel with high strength and corrosion resistance. It is suitable for packaging materials such as plastic composite film and aluminum foil composite film. It can vacuum or gas-filled packaging of solid, liquid, powder and paste items.
2. Working Principle
Vacuum treatment: After closing the vacuum chamber cover, the vacuum pump starts to extract air from the vacuum chamber and stops pumping after reaching the set vacuum degree.
Sealing operation: The pressure valve opens automatically, the airbag is inflated to push the support plate and phenolic plate down to the sealing point, and the heating strip is powered on and heated to complete the sealing.
Inflation function (optional): Some models support the filling of inert gases such as nitrogen to enhance the pressure resistance, gas barrier and preservation effect.
Cyclic operation: When one vacuum chamber is working, the other vacuum chamber can be loaded or unloaded to achieve continuous production.
3. Main features
Efficient and continuous operation: The dual-chamber alternating working mode significantly improves packaging efficiency, which is 1.5 times that of a single-chamber vacuum packaging machine.
Wet and dry use: Supports packaging of products with high water content, and the unique inclined table design prevents water loss.
Automatic control: Using a microcomputer controller, the vacuum time, heat sealing time and temperature can be adjusted, and the operation is simple.
Strong durability: The vacuum chamber uses a 4mm thick 304 stainless steel plate, which will not leak or deform after long-term use.
Multifunctional expansion: The inflation device can be configured to meet the packaging needs of different products.

5. Application areas
Food industry: meat products, seafood, preserved fruits, pickles, grains, etc., to extend shelf life and prevent oxidation and mildew.
Pharmaceuticals and chemicals: chemicals, medicinal materials, electronic components, precision instruments, etc., moisture-proof, rust-proof, and pollution-proof.
Other areas: clothing, hardware products, etc., provide moisture-proof, anti-oxidation and transportation protection.
6. Advantage analysis
Improve production efficiency: alternating work of double chambers reduces waiting time and is suitable for medium-volume continuous production.
Extend shelf life: vacuum or gas-filled packaging effectively isolates oxygen to prevent food oxidation and microbial reproduction.
Reduce loss: Prevent products from getting damp, vibrating and deforming, and reduce loss during transportation and storage.
Convenient operation: Automated control reduces manual intervention and improves packaging consistency.
7. Purchase suggestions
Choose according to production scale: For medium-volume production, it is recommended to choose a double-chamber vacuum packaging machine, and for small-volume production, a single-chamber model can be considered.
Pay attention to packaging material compatibility: Make sure that the equipment supports the material and thickness of the packaging bag used.
Consider the requirements for inflation function: If you need to enhance the pressure resistance and gas barrier effect, you can choose a model equipped with an inflation device.
Pay attention to equipment stability: Choose equipment made of high-quality stainless steel and with stable vacuum pump performance.
8. Maintenance and care
Regular cleaning: Clean the vacuum chamber and sealing device after each use 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.
Professional maintenance: Contact professional maintenance personnel in time when the equipment fails to avoid damage caused by self-disassembly.
