How It Compares
| Single-layer coffee bag machine | The C19D provides dual-layer protection with inner and outer sealing, improving barrier performance and shelf life, but requires more film and setup time |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids heat damage to coffee oils and preserves aroma, but requires an air supply and more precise maintenance |
| Manual inner and outer bag packing | The C19D automates the entire process and holds consistent fill weight, but requires a fixed floor space of 1200 x 900 mm and trained operator |
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 and confirm stability
- 5Run ten sample bags and verify fill weight, seal integrity, and bag length
- 6Enable nitrogen flushing if required, using the reserved connector and external machine
