1. Loading and Closing: The operator places the bag opening containing the product onto the heat sealing strip of the vacuum chamber tray and closes the vacuum lid.
2. Vacuum Extraction: The vacuum pump activates, rapidly removing air from the vacuum chamber and inside the bag to achieve the preset vacuum level (e.g., ≤100mbar).
3. Heat Sealing: Following vacuum extraction or inert gas filling, nickel-chromium alloy heating strips instantly heat the packaging film. Precise temperature and time control ensure reliable sealing.
4. Cooling and Exhaust: Upon sealing completion, the cooling system rapidly lowers temperature to set the seal.
5. Alternating Operations: The vacuum chamber exhausts and depressurizes, automatically unlocking the vacuum lid. Simultaneously, the other vacuum chamber can begin processing the next batch.

1. Control System: Integrated microcomputer intelligent control panel with strong anti-interference capability, enabling precise setting and storage of parameters such as vacuum level, heat sealing time, and temperature.
2. Vacuum Pump: Serving as the equipment’s “heart,” this rigorously inspected industrial-grade vacuum pump (imported brands available as optional) delivers stable, high-efficiency pumping capacity (e.g., 20m³/h or higher).
3. Ergonomic Hinge: Specially designed vacuum lid hinge mechanism significantly reduces operator fatigue, enabling effortless opening and closing for extended continuous operation.
4. Durable Main Body Material: The entire main structure is crafted from 304 stainless steel, ensuring a sleek, professional appearance while offering exceptional corrosion resistance for long-term use in harsh production environments.
5. V-Shaped Sealing Strip: The V-shaped vacuum chamber sealing strip is made from high-density, pressure-resistant, and wear-resistant material. It provides strong sealing performance and extended service life, reducing replacement frequency and production costs.
6. Mobility and Support: Equipped with heavy-duty casters featuring brakes for easy positioning and secure anchoring, ensuring operational stability.

Key Maintenance Points

• Before Daily Operation: Inspect the vacuum pump oil level indicator window to ensure oil is within the standard range, preventing operation with insufficient oil.
• Quarterly Maintenance: Replace the exhaust filter to maintain vacuum efficiency and equipment cooling.
• Annual Deep Maintenance: Replace the oil filter, perform a comprehensive inspection of the vacuum pump, and thoroughly check the wear condition of the V-shaped seal.
• Environmental Requirements: Operate within a clean workshop environment with temperatures controlled between 5-40°C and relative humidity ≤80%.

• Food Industry: Preserving agricultural products like dates and walnut kernels; sealing granular/bulk foods such as meat products, pickles, seaweed products, and yeast.
• Medical & Health Industry: Sterile sealing of medical devices, pharmaceutical raw materials, traditional Chinese medicine slices, and chemical reagents.
• Industrial Sector: Anti-oxidation and moisture-proof packaging for electronic components and hardware fittings.
• Other Applications: Packaging of chemical raw materials, condiments, local specialties, aquatic products, and seafood.
