Coffee Stick Pack Machine

Engineered for automated vertical form-fill-seal operations, this continuous-motion system meters, forms, fills, and seals free-flowing and non-free-flowing coffee powders into narrow tubular sachets with consistent seal integrity and minimal material waste.

Multi-Lane Synchronization: Independent servo-driven film pulling belts ensure uniform tension across all lanes simultaneously.

Volumetric Augers: Direct-drive stepping motors govern individual auger screws for precise powder metering without packing degradation.

Pneumatic Sealing Jaws: Constant-temperature heating bars maintain precise vertical and horizontal seal pressures to eliminate leak paths.

Modular Control Architecture: Programmable logic controller paired with a 10-inch color touchscreen interface for real-time parameter adjustment and error diagnostics.

Integrated Film Tracking: Automatic edge-position control sensors correct film drift continuously during high-speed production runs.

Instant Coffee Processing: Single-serve packaging of spray-dried and freeze-dried soluble coffee granules.

Coffee Premix Packaging: Automated dosing of 3-in-1 coffee blends containing milk powder and sugar additives.

Specialty Ground Coffee: Packaging of finely pulverized espresso or drip coffee grounds under modified atmospheric conditions.

Aroma Retention: Hermetically sealed longitudinal and transverse fins protect volatile aromatic compounds from environmental oxidation.

Portion Control: Exact volumetric dosing eliminates overfilling and ensures strict grammage tolerances per individual sachet.

Material Compatibility: Operates with laminated structures including PET/AL/PE, OPP/PE, and paper-foil-polyethylene laminates.

Tear Notch Integration: Precision laser or mechanical scoring creates clean directional opening mechanisms for end users.

Film Unwinding: Roll stock mounted on motorized spindles feeds through dancer arms to maintain constant web tension.

Forming Operation: Flat film passes over individual forming collars, folding into tubular shapes around filling nozzles.

Longitudinal Sealing: Heated vertical sealing jaws press the overlapping film edges together continuously.

Volumetric Dosing: Auger screws rotate inside vertical funnels, discharging measured powder charges down the forming tubes into the open sachets.

Transverse Sealing & Cutting: Cross-sealing jaws apply thermal pressure to form the top seal of the current pack and the bottom seal of the next, while an integrated knife severs the units.

Auger Screw Precision: Stainless steel helical screws match specific powder bulk densities to prevent bridging and compaction.

Agitator Blades: Independent low-shear mixing paddles inside the powder hopper maintain consistent product density above the dosing screw.

Quick-Release Funnels: Tool-free disassembly allows operators to remove augers, funnels, and tubes within 10 minutes for thorough sanitation.

Width Adjustments: Interchangeable forming tube assemblies alter sachet widths from 15mm up to 50mm.

Length Variations: Touchscreen-controlled encoder settings adjust cut-off lengths without changing mechanical gear sets.

Serrated Cutting: Zigzag cutting dies prevent fraying of multi-layer barrier films and ensure straight tearing lines.

Contact Parts Sanitation: Food-grade 304 stainless steel construction on all surfaces touching coffee products, complying with sanitary equipment standards.

Seal Integrity Verification: Pressure decay testing protocols validate hermetic seal performance during prototype and factory acceptance trials.

Electrical Safety Compliance: Control enclosures wired to industrial standards featuring overload protection, emergency stop circuits, and safety interlocks on guarding doors.

Export Crating: Sealed fumigation-free wooden crates secure machinery with internal moisture barrier wrapping and shock-absorbing mounts.

Component Inventory: Critical wear items, including heating elements, thermocouples, and drive belts, ship inside a dedicated toolkit container.

Technical Documentation: Comprehensive wiring diagrams, PLC program backups, pneumatic schematics, and English language operation manuals accompany every shipment.

1.What is the typical output speed per lane?
Operating speeds range from 30 to 70 packs per minute per lane, governed by the flow characteristics of the coffee powder and the sealing dwell time required by the laminate film.

2.How does the machine handle hygroscopic coffee powders?
Enclosed dosing funnels combined with optional nitrogen gas flushing prevent moisture absorption and oxidation during the drop and seal phases.

3.What changeover time is required for different stick pack widths?
Switching to a different sachet width requires replacing the forming sets and filling tubes, a procedure completed by trained operators in approximately 30 minutes.

4.Can the system integrate with downstream cartoning equipment?
Mechanical discharge conveyors and counting guides coordinate directly with secondary cartoning systems or multi-lane grouping mechanisms.

5.What utilities must be provisioned on the factory floor?
Facilities require a stable 3-phase electrical supply matched to the total wattage rating and a compressed air line delivering dry, filtered air at 0.6 MPa.
