Key Benefits
- Forms and seals inner and outer bags simultaneously to double packing speed compared to sequential machines
- Ultrasonic sealing avoids heat damage to coffee aroma and maintains a narrow, clean seal edge
- Volumetric cup filling delivers consistent 5 to 15 g per bag with no manual adjustment needed
- Stepper motor controls outer bag sealing for accurate positioning and stable bag length
- PLC control with human machine interface allows simple operation and quick format changeover
- Supports nitrogen flushing via a reserved connector to extend shelf life of roasted coffee
Application Scenarios
- Robusta coffee roasters packaging bulk batches for retail or food service under their own label
- Contract packers handling multiple coffee brands with different bag sizes and fill weights
- Coffee producers switching from manual packing to in-house automation with consistent bag weight
- Blenders producing ready-to-brew coffee bags with a sealed inner layer for freshness
Who It Is For
- Coffee roasters moving from outsourced packing to in-house automatic bagging
- Contract packers serving multiple coffee brands with short batch runs
- Producers of Robusta or blended coffee needing a sealed inner bag for freshness
- Buyers replacing a slow or inconsistent manual packing line with a fully automatic system
Problems It Solves
- Manual packing of inner and outer bags leads to inconsistent fill weight and slow output
- Heat sealing damages coffee aroma and causes film degradation at the seam
- Inaccurate bag length positioning causes misalignment in packaging and display
- Lack of nitrogen flushing leads to faster oxidation and shorter shelf life of roasted coffee
- No integrated system for forming and sealing both bags at once reduces line efficiency
Technical Features
- Ultrasonic sealing for inner and outer bags with no heat or adhesive required
- Volumetric cup filler for 5 to 15 g per bag with consistent fill volume
- Stepper motor controls outer bag sealing for accurate length positioning
- PID temperature controller for precise heat control during sealing
- PLC control system with human machine interface for easy operation
- All food contact parts made of SUS304 stainless steel for hygiene and durability
- Reserved connector for nitrogen flushing to extend shelf life
- Optional flat cut, date printer, and easy tear device for added functionality

How It Compares
| Manual inner and outer bag packing | The C19D automates both bag formation and sealing, eliminating labor and inconsistency, but requires a fixed footprint and trained operator |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing preserves coffee aroma and avoids film scorching, but requires an air supply and precise control |
| Sequential inner and outer bag machine | The C19D forms and seals both bags at once, improving speed, but has a higher initial setup cost |

- 3Set the volumetric cup to the desired fill weight between 5 and 15 g
- 4Adjust the outer bag length using the stepper motor control for accurate positioning
- 5Run a test batch of 10 bags and verify fill weight, seal integrity, and bag alignment
- 6Install optional devices like date printer or easy tear feature as needed
