How It Compares
| Manual inner and outer bag packing | The C19D automates both inner and outer bag sealing, eliminating hand labor and ensuring consistent fill and seal quality |
|---|---|
| Heat-sealed drip bag machine | Ultrasonic sealing avoids heat damage to coffee aroma and film clarity, but requires an air supply for operation |
| Single bag machine | The C19D packs inner and outer bags simultaneously, increasing output by up to 100% compared to sequential machines |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load the inner and outer film rolls matching your chosen 180 mm and 200 mm widths
- 3Set bag length and width using the PLC interface within the 50-120 mm range
- 4Configure the volumetric cup to 5 to 15 g per bag and calibrate with your coffee blend
- 5Enable nitrogen flush connection if using nitrogen generator, otherwise leave inactive
- 6Run 10 test bags and verify fill weight, seal integrity, and bag alignment before batch start
