Key Benefits
- Packs both inner and outer bags simultaneously to double the output compared to sequential machines
- Ultrasonic sealing avoids heat damage to coffee aroma and prevents film melting at the seam
- Volumetric cup filling delivers consistent 5 to 15 g per bag with minimal variation across batches
- Stepper motor controls outer bag length positioning for accurate and repeatable bag size
- PLC control with human machine interface allows simple operation and quick setup changes
- Food-grade SUS304 stainless steel parts ensure compliance with food safety standards
Application Scenarios
- Coffee roasters producing small to medium batches of single-origin or blended coffee for retail or food service
- Contract packers handling multiple coffee brands with different bag sizes and fill weights
- Producers requiring nitrogen flushing to extend shelf life of roasted coffee in sealed bags
- Brands launching new coffee lines that need a reliable, automated inner and outer bagging solution
Who It Is For
- Coffee roasters transitioning from manual packing to in-house automatic bagging
- Contract packers serving multiple coffee brands with short batch runs and frequent changeovers
- Producers who need double-layer protection for ground or granule coffee to prevent oxidation
- Buyers replacing older machines with inconsistent sealing or unstable bag positioning
Problems It Solves
- Manual inner and outer bagging is slow and inconsistent, leading to high labor cost and variable bag quality
- Heat sealing damages coffee aroma and can melt film layers, especially on plastic-aluminum-plastic films
- Inaccurate bag length positioning causes misalignment and waste during outer bag sealing
- Lack of nitrogen flushing leads to faster degradation of roasted coffee in sealed bags
- Non-food-grade materials or poor sealing integrity risk failing customer or retail safety audits
Technical Features
- Ultrasonic sealing for both inner and outer bags with no heat or adhesive required
- Stepper motor controls outer bag length positioning for accurate and stable sealing
- PID temperature controller for precise temperature adjustment during sealing
- PLC control system with human machine interface for easy operation and monitoring
- Volumetric cup filling system for consistent 5 to 15 g per bag across all coffee types
- Optional date printer, easy tear device, and flat cut device for added functionality
- Reserved connector for nitrogen flushing to extend coffee shelf life
- High-specification components including imported cylinders for stable performance

How It Compares
| Single-layer coffee bag machine | The C19H provides double-layer protection for coffee, improving shelf life and barrier performance, but requires more film and setup time |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids film melting and preserves coffee aroma, but requires an air supply and more precise maintenance |
| Manual inner and outer bagging | The C19H automates both steps and improves consistency, but requires a fixed floor space of 1200 x 900 mm and trained operator |
