How It Compares
| Single-layer drip coffee bag machine | The C19D forms both inner and outer bags in one cycle, improving efficiency and barrier protection, but requires more setup time and floor space |
|---|---|
| Heat-sealed outer bag machine | Ultrasonic sealing avoids heat damage to film and creates a narrower seal, but requires an air supply and is sensitive to film thickness variation |
| Manual inner and outer bag packing | The C19D replaces a hand-filling team and ensures consistent bag size and fill weight, but requires a trained operator and fixed installation |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load the selected inner and outer film rolls matching the 180 mm and 200 mm widths
- 3Set inner and outer bag size within the 50-75 mm and 85-120 mm range using the control panel
- 4Enter target fill weight between 5 and 15 g and calibrate the volumetric cup with your coffee
- 5Run ten test bags and check fill weight, seal integrity, and bag alignment before batch start
- 6Install optional devices like date printer or nitrogen flush connector as needed
