How It Compares
| Manual inner and outer bag packing | The C19D replaces a hand-filling team and ensures consistent fill weight and seal quality, but requires a fixed footprint of 1200 x 900 mm and trained operator |
|---|---|
| Heat-sealed drip bag machine | Ultrasonic sealing avoids film scorching and maintains aroma integrity, but requires an air supply and higher initial setup cost |
| Single-layer bag machine | The C19D produces both inner and outer bags in one cycle, improving efficiency, but uses more film and requires more space |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load the selected film roll matching the inner or outer bag width (180 mm or 200 mm)
- 3Set the bag length and fill weight using the PLC interface and calibrate the volumetric cup
- 4Install optional devices such as date printer or easy tear feature if required
- 5Run a test batch of 10 bags and check fill weight, seal quality, and ear alignment
- 6Clean the filling cup and sealing heads between different coffee types to avoid cross-contamination
