How It Compares
| Manual inner and outer bag sealing | The C19D automates both inner and outer bag sealing, improving consistency and output, but requires a fixed footprint and trained operator |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids scorching coffee oils and creates a narrower seal, but requires an air supply and precise control |
| Single bag machine | The C19D produces inner and outer bags in one cycle, increasing efficiency, but requires more floor space and setup time |
Use Guide
- 1Connect a clean dry power supply at 220V 50Hz single phase and ensure the 3.7 kW rating is met
- 2Load the selected film roll (180 mm for inner, 200 mm for outer) and align it with the guide rollers
- 3Set the bag size within the specified inner and outer dimensions using the control panel
- 4Enter the target fill weight between 5 and 15 g and calibrate the volumetric cup with your coffee
- 5Run a test batch of 10 bags and check fill weight, seal quality, and positioning
- 6Enable nitrogen flushing integration if required and connect to the nitrogen machine
- 7Clean the filling cup and sealing heads between different coffee types to prevent cross-contamination
