How It Compares
| Manual inner and outer bag sealing | The C19D automates both steps and runs 40 to 60 bags per minute, but requires a fixed footprint and trained operator |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids film scorching and preserves coffee aroma, but requires an air supply and higher initial component cost |
| Single-layer bag machine | The C19D produces sealed inner and outer bags for better protection and shelf life, 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 film roll matched to your chosen inner and outer bag size and film type
- 3Set the volumetric cup to the desired fill weight between 5 and 15 g
- 4Adjust the stepper motor for outer bag length positioning to match your bag size
- 5Run a test batch of 10 bags and verify fill weight, seal integrity, and bag length
- 6Install optional devices such as date printer or easy tear feature as needed
