How It Compares
| Manual inner and outer bagging | The C19D automates both bag stages and holds fill weight consistently, but requires a fixed footprint of 1200 x 900 mm and trained operator |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids film scorching and maintains a narrow seal, but requires an air supply and more precise film handling |
| Single bag machine | The C19D produces inner and outer bags simultaneously, increasing output, but uses more film and requires wider roll stock |
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 using the human machine interface
- 5Run ten sample bags and check fill weight, seal integrity, and bag alignment before starting the batch
- 6Clean the volumetric cup and sealing heads between different coffee types to prevent aroma carry-over
