How It Compares
| Manual inner and outer bag assembly | The C19H automates both bag stages and runs 40 to 60 bags per minute, but requires a fixed footprint of 1200 x 900 mm and trained operator |
|---|---|
| Heat sealed dual-bag machine | Ultrasonic sealing avoids scorching and waste edge, but requires an air supply and is not suitable for all film types |
| Single-layer filter bag machine | The C19H provides a protective outer layer and nitrogen flushing capability, but uses more film and requires more setup time |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load the inner and outer film rolls matched to your chosen bag size and film type
- 3Set inner bag size to 50-75 mm and outer bag size to 85-120 mm on the control panel
- 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 outer bag positioning
- 6Use the reserved connector to link with a nitrogen generator if shelf life extension is required
