Key Benefits
- Produces inner and outer bags simultaneously, reducing line time compared to sequential packing
- Ultrasonic sealing avoids heat damage to sensitive coffee film and prevents scorching of aroma
- Volumetric cup filling delivers consistent 5 to 15 g per bag with no manual adjustment needed
- Stepper motor controls outer bag sealing for precise positioning and stable bag length
- PLC control with human machine interface allows simple operation and quick changeover
- SUS304 food-grade stainless steel parts ensure compliance with food safety standards
Application Scenarios
- Coffee roasters packaging single-origin Arabica in dual-layer bags for direct-to-consumer e-commerce
- Contract packers handling multiple coffee brands with short batch runs and quick format changes
- Roasters transitioning from manual packing to in-line automatic dual-bagging for consistency
- Brands requiring nitrogen flushing to extend shelf life, using the reserved connector for integration
Who It Is For
- Coffee roasters moving from hand packing to automated inner and outer bagging
- Contract packers serving multiple coffee brands with different bag sizes and fill weights
- Producers who need dual-layer protection for granule and powder coffee to maintain freshness
- Buyers replacing older machines that use heat sealing and cause film degradation
Problems It Solves
- Manual dual-bagging is slow and inconsistent; the C19D automates both inner and outer bag formation
- Heat sealing damages coffee film and can degrade aroma, while ultrasonic sealing preserves material integrity
- Inconsistent fill weight from hand filling leads to customer complaints and giveaway loss
- Lack of nitrogen flushing capability in older machines reduces shelf life of roasted coffee
- Older machines with mechanical positioning fail to maintain accurate bag length across batches
Technical Features
- Ultrasonic sealing for both inner and outer bags with no heat or adhesive required
- Stepper motor controls outer bag sealing for accurate positioning and stable length
- PID temperature controller for precise heat control during sealing process
- PLC control system with human machine interface for easy operation and monitoring
- Volumetric cup filler ensures consistent 5 to 15 g per bag across the range
- Reserved connector for nitrogen flushing machine integration to extend shelf life
- All food-contact parts made of SUS304 stainless steel for hygiene and durability

How It Compares
| Single-layer heat-sealed coffee bag machine | The C19D provides dual-layer protection with better barrier properties and shelf life, but requires more film and setup time |
|---|---|
| Manual dual-bagging process | The C19D automates both inner and outer bag formation, increasing speed and consistency, but requires a fixed power and air supply |
| Older mechanical positioning machines | The C19D uses a stepper motor for precise outer bag length control, reducing waste and misalignment |
Use Guide
- 1Connect a single phase 220V 50Hz power supply and ensure stable voltage
- 2Load the inner and outer film rolls matched to your bag size and film type
- 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 consistent positioning
- 5Run a test batch of 10 bags and check fill weight, seal integrity, and bag length
- 6Install optional devices like date printer or easy tear feature as needed before production
