How It Compares
| Manual inner and outer bag packing | The C19D replaces a hand-filling team and ensures consistent fill weight and seal alignment, but requires a fixed floor space of 1200 x 900 mm and trained operator |
|---|---|
| Heat-sealed drip bag machine | Ultrasonic sealing avoids film scorching and maintains a narrow seal edge, but requires an air supply and stepper motor control |
| Single-layer coffee bag machine | The C19D produces both inner and outer bags in one line, improving efficiency, but requires more setup time for dual film handling |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load the inner and outer film rolls matching the 180 mm and 200 mm widths
- 3Set the inner and outer bag size within the 50-75 mm and 85-120 mm length range
- 4Enter target fill weight between 5 and 15 g and calibrate the volumetric cup with your coffee
- 5Run ten sample bags and check fill weight, seal integrity, and bag length before batch start
- 6Use the reserved connector to link with a nitrogen flushing system if shelf life extension is required
