Customization Options
- Choice of inner and outer bag sizes within the specified range

How It Compares
| Separate inner and outer bag machines | The C19D combines both steps into one line, reducing footprint and labor, but requires a single machine with dual sealing capability |
|---|---|
| Heat-sealed drip coffee machine | Ultrasonic sealing avoids film scorching and maintains film integrity, but requires an air supply for the sealing head |
| Manual bagging with hand sealing | The C19D replaces a manual team and ensures consistent fill and seal, but needs a fixed power and air supply |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load the inner and outer film rolls at 180 mm and 200 mm widths respectively
- 3Set the inner and outer bag sizes 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 quality, and bag positioning
- 6Install optional devices like date printer or nitrogen flush connector as needed
