The Keypack Intelligent  (Kunbupack)   Double-Head Vacuum Nitrogen-Filling Can Sealer is a new-generation can sealing machine specifically designed for high-end powdered products such as milk powder and protein powder. It is suitable for sealing various round cans, including tinplate and aluminum cans, utilizing a “vacuum first, nitrogen fill second” process. Integrated electrical control and HMI allow automatic lid application, can infeed/outfeed, vacuum pumping, nitrogen filling, and oil-free full-automatic sealing. Operating parameters can be easily set and adjusted via the HMI for different can types, ensuring efficient and stable production.

Functional Features

• High-quality construction: Exterior and main components made of 304 stainless steel for high cleanliness

• Vacuum sealing system: Uses high-temperature resistant, leak-proof vacuum-specific fluororubber sealing rings

• Intelligent control: Equipped with XINJIE touchscreen and SIEMENS PLC for simple operation and orderly action

• Precision sensors: OMRON photoelectric sensors for position detection; pneumatic actuators, valves, and cylinder sensors by AIRTAC

• Double-seaming rollers: Ensure excellent sealing quality, smooth and uniform without scratching or yellowing; rollers processed with advanced heat treatment for long service life

• Adjustable parameters: HMI allows quick modification based on sealing quality and residual oxygen content

• Oil-free automated operation: Cylinders and motors drive all actuators, maintaining a clean production environment

• Fault alarm system: Alerts for lid absence, lid shortage, can jamming, servo failure, cylinder malfunction, etc., for quick troubleshooting

• Dust control design: Automatic timed dust suction and vacuum-nitrogen filling method prevent dust resuspension

• Clean and efficient: Oil-free and maintenance-free bearings improve hygiene and production efficiency
