Key Benefits
- Forms and seals inner and outer bags simultaneously, reducing line footprint and labour compared to separate machines
- Stepper motor controls outer bag length with high accuracy, reducing misalignment and film waste
- PID temperature control ensures stable heat sealing across a batch, preventing under or over-sealing
- PLC control with touch screen interface allows quick setup and real-time monitoring of production parameters
- SUS304 stainless steel construction on main components ensures hygiene and durability in food processing environments
- Built-in connector for nitrogen flushing extends shelf life by reducing oxidation in coffee
- Measuring cup filler delivers consistent fill weight across 5 to 15 g per bag without manual adjustment
Application Scenarios
- Coffee roasters packaging Robusta beans in drip bags for retail or food service distribution
- Contract packers handling multiple coffee brands with short batch runs and frequent format changes
- Small to mid-sized roasters moving from manual packing to in-house automated drip bagging
- Producers requiring nitrogen flushing to preserve freshness in high-oil or roasted coffee blends
Who It Is For
- Coffee roasters transitioning from hand packing to automated drip bag production
- Contract packers serving multiple coffee brands with different bag sizes and fill weights
- Producers of Robusta and other coffee types needing a sealed inner filter bag with outer protection
- Buyers replacing older machines with inconsistent sealing or slow cycle times
Problems It Solves
- Manual inner and outer bag assembly causes inconsistent sealing and high labour cost
- Inaccurate bag length positioning leads to misaligned seals and film waste
- Older machines with basic thermostats produce variable seal quality across batches
- Lack of nitrogen flushing capability shortens shelf life of roasted coffee
- Separate machines for inner and outer bags increase floor space and complexity

How It Compares
| Separate inner and outer bag machines | The C19II combines both steps into one line, reducing floor space and operator handling, but requires a single machine footprint of 1200 x 900 mm |
|---|---|
| Manual drip bag assembly | The C19II replaces hand filling and sealing with consistent automation, but needs a 220V 50Hz power supply and compressed air if nitrogen is used |
| Basic thermal sealing machine | The C19II uses PID temperature control for stable sealing, while older models may have inconsistent heat application |
Use Guide
- 1Connect a clean dry power supply at single phase 220V 50Hz and 3.7 kW
- 2Load the chosen film roll (180 mm inner, 200 mm outer) and align it with the forming guide
- 3Set inner and outer bag sizes within the 50-75 mm and 85-120 mm range via the touch screen
- 4Enter target fill weight between 5 and 15 g and calibrate the measuring cup with actual coffee
- 5Run 10 sample bags and check seal quality, fill weight and bag length before batch start
- 6If using nitrogen, connect the nitrogen flushing machine to the reserved connector before sealing
