Key Benefits
- Forms and seals inner and outer bags at the same time, reducing cycle time and increasing throughput
- Ultrasonic sealing ensures a clean, narrow seal without heat damage to coffee aroma or film integrity
- Volumetric cup filling delivers consistent fill weight across 5 to 15 g per bag with minimal giveaway
- Stainless steel food contact parts (SUS304) meet food safety standards for direct product contact
- Stepper motor control for outer bag sealing ensures accurate positioning and stable bag length
- Built-in connector for nitrogen flushing extends shelf life by reducing oxidation in the packed coffee
Application Scenarios
- Coffee roasters producing small to medium batches of single-origin drip coffee for retail or direct-to-consumer sale
- Contract packers handling multiple coffee brands with quick format changeover between bag sizes
- Packaging teams replacing manual filling and hand-sealing with a fully automated line
- Brands requiring nitrogen flushing to preserve freshness in sealed drip coffee bags
Who It Is For
- Coffee roasters transitioning from outsourced packing to in-house drip bag production
- Packaging teams needing consistent inner and outer bag sealing for premium coffee
- Brands that require nitrogen flushing to extend shelf life and maintain aroma
- Producers using filter paper, PLA, or multi-layer films and needing a machine that handles them reliably
Problems It Solves
- Manual filling leads to inconsistent bag weight and high labor cost for high-volume drip coffee
- Heat sealing damages delicate coffee aroma and can melt film layers in multi-layer packaging
- Separate inner and outer bag machines increase floor space, complexity and cycle time
- Lack of nitrogen flushing leads to faster oxidation and reduced shelf life in packaged coffee
- Inaccurate bag length or sealing position causes misalignment and rejects during packaging
Technical Features
- Ultrasonic sealing for inner and outer bags with precise, narrow seam and no heat damage
- Volumetric cup filling system for 5 to 15 g per bag with consistent weight control
- Stepper motor control for outer bag sealing with accurate length positioning
- PID temperature controller for stable and precise heat application in sealing zones
- PLC control with human machine interface for easy operation and parameter setting
- All food contact parts made of SUS304 stainless steel for hygiene and durability
- Reserved connector for nitrogen flushing to extend shelf life of packed coffee

How It Compares
| Separate inner and outer bag machines | The C19D combines both steps into one line, reducing floor space and cycle time, but requires a single machine footprint of 1200 x 900 mm |
|---|---|
| Heat sealed drip coffee machine | Ultrasonic sealing avoids film scorching and maintains aroma, but requires an air supply and precise control |
| Manual packing with hand sealing | The C19D replaces labor-intensive packing and ensures consistent weight and seal, but needs trained operator and fixed power supply |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load the selected film roll (180 mm for inner, 200 mm for outer) and align the film path
- 3Set inner and outer bag size within the 50-75 mm and 85-120 mm length ranges
- 4Enter target fill weight between 5 and 15 g and calibrate the volumetric cup with your coffee
- 5Enable nitrogen flushing if required and connect to nitrogen generator
- 6Run 10 test bags and verify fill weight, seal quality, and bag length before batch start
- 7Clean the volumetric cup and sealing heads between different coffee types to avoid flavor carry-over
