The machine combines vacuuming and nitrogen (N2) flushing: it removes most of the air from the bag (vacuum) and then fills the package headspace with nitrogen before heat sealing. This displaces oxygen to slow oxidation and microbial growth, extending shelf life for many foods.
It is designed for heat-sealable plastic bags (PE, PA/PE, PP and other common laminates suitable for heat sealing). For best results use bags specified for vacuum and modified-atmosphere packaging. If you have a specific film, check compatibility with the seller or test a sample.
Maximum conveyor speeds are available in multiple options: 5, 8, 9, 10, 12, or 14 m/min. Actual throughput (packages per minute) depends on bag length and cycle settings. Example: at 14 m/min a 0.14 m (14 cm) bag length could theoretically be ~100 bags/min, but practical throughput is lower due to handling and overlap—provide your bag size for a precise estimate.
Sealing width is adjustable between 6–14 mm. The sealing temperature is adjustable from 0 to 300°C to accommodate different film types and thicknesses.
The machine requires 220 V, 50 Hz and consumes 875 W of power. Ensure a properly grounded circuit of sufficient capacity is available for safe operation.
Maximum conveyor loading is 3 kg (per package on the conveyor). The machine dimensions are 1025 × 450 × (940 + 140 adjustable) mm, so ensure your items fit the conveyor width and the horizontal layout.
Yes — it is described as automatic and designed for straightforward operation. Typical controls include start/stop, temperature adjustment, speed control, and vacuum/nitrogen timing. Training or a short run-in period is recommended for optimal parameter setup.
You will need an external nitrogen source (gas cylinder or generator) and a pressure regulator, fittings and tubing compatible with the machine. Required nitrogen purity, pressure and flow will be provided in the machine manual or by the supplier—confirm those details when purchasing.
Increasing vacuum and flushing with nitrogen reduces residual oxygen and slows oxidation and aerobic microbial growth. Optimal settings depend on the product (moisture, respiration, fat content). Trial runs and shelf-life testing are recommended to determine ideal vacuum time and nitrogen flush volume for each product.
Regular maintenance includes cleaning conveyor and sealing surfaces, inspecting and replacing sealing wires/Teflon tape or heating elements as needed, checking vacuum pump oil (if applicable), inspecting belts and sensors, and verifying nitrogen fittings for leaks. Follow the manufacturer's maintenance schedule in the manual.
Follow standard machine safety: keep hands clear of moving parts and hot sealing bars, use proper guarding, disconnect power before servicing, ensure good ventilation when sealing food, and follow local regulations for gas cylinder handling when using nitrogen. Only trained personnel should operate and maintain the equipment.
Yes — the horizontal configuration and conveyor make it suitable for a range of shapes and small-to-medium-sized fresh products (snacks, meats, vegetables). However, delicate produce may require gentler handling and optimized vacuum/nitrogen parameters to avoid product damage.
Common consumables include sealing wires, Teflon tape, heating elements, belts and vacuum pump oil (if applicable). Availability varies by supplier—confirm spare parts support and lead times with the manufacturer or dealer before purchase.
Warranty terms, technical support contacts and spare parts ordering are provided by the machine supplier or manufacturer. Ask your seller for the user manual, service contacts and warranty details at the time of purchase; keep your serial number and purchase receipt for service requests.
