Key Capabilities of the TL-SP-1P Powder Stick Packing Machine

( 01 ) Servo-Controlled Auger Filling with Real-Time Weight Compensation

The servo-driven auger system provides precise control over powder dispensing through programmable rotation parameters.

Operators set target fill weights through the touchscreen interface, and the control system calculates optimal auger revolutions for each bag.

Real-time feedback adjusts auger speed to compensate for powder density changes as hopper levels decrease. Fill weight consistency remains within ±1% throughout entire production runs without manual intervention.

( 02 ) Hermetic Sealing for Moisture-Sensitive Powder Protection

Many powder products—milk powder, pharmaceutical formulations, hygroscopic supplements—degrade rapidly when exposed to moisture.

The TL-SP-1P forms hermetically sealed stick packs using heat-sealing technology with adjustable temperature and pressure parameters.

Sealing width ranges from 5-10 mm, creating robust seals that protect contents throughout distribution chains spanning multiple climate zones. Compatible barrier films include aluminum foil laminates providing moisture vapor transmission rates below 0.1 g/m²/day.

( 03 ) Dust-Controlled Filling Environment

Powder packaging operations generate airborne particles affecting product quality, equipment longevity, and workplace safety.

The TL-SP-1P incorporates enclosed hopper design, sealed auger tube assembly, and controlled powder release to minimize dust generation.

Optional dust collection attachments capture escaped particles before they contaminate sealing surfaces or accumulate on machine components. Reduced dust translates to cleaner operations, less product waste, and extended maintenance intervals.

Why Powder Products Require Auger Screw Dosing Technology

Powder materials present unique packaging challenges compared to granular products. Fine particles aerate during handling, compress unpredictably under their own weight, and generate dust during filling operations. Density varies throughout the hopper as powder settles, making volumetric measurement unreliable. The TL-SP-1P powder stick packing machine solves powder-specific problems through servo-driven auger screw technology—a rotating helical screw that moves powder from hopper to bag with precise rotational control.

The auger screw dosing system delivers fill weight accuracy within ±1% across varying powder densities and flowability characteristics.

Each auger revolution dispenses a predictable powder volume, and servo motor control adjusts rotation speed in real-time to maintain target fill weights.

The enclosed auger tube minimizes dust escape and product contamination while maintaining clean operation throughout production runs.

Powder flowability ranges from free-flowing materials like table salt to cohesive powders like cocoa that bridge and clump in hoppers. The TL-SP-1P handles powders across the flowability spectrum through adjustable auger configurations, hopper agitation options, and optimized screw geometry for different material characteristics.

Powder Products Packaged with the TL-SP-1P

( 01 ) Food and Beverage Powder Applications

Milk powder and infant formula require precise dosing for nutritional accuracy and hermetic sealing for extended shelf life.

Coffee powder and cocoa powder demand oxygen barrier protection to preserve flavor compounds and prevent oxidation.

Protein powder portions need consistent fill weights for dietary tracking. Seasoning powders and soup bases benefit from single-serve convenience formats. The TL-SP-1P delivers pharmaceutical-grade accuracy for food applications where dosing consistency affects product quality and brand reputation.

( 02 ) Pharmaceutical and Nutraceutical Powder Applications

Medicinal powders require fill weight accuracy meeting regulatory standards—the TL-SP-1P achieves ±1% consistency suitable for pharmaceutical manufacturing environments.

Vitamin powders and mineral supplements need moisture barrier packaging preventing degradation of active ingredients. Probiotic formulations require gentle handling avoiding heat damage to live cultures.

Electrolyte powders and oral rehydration salts need accurate dosing for therapeutic effectiveness. Stick pack formats provide convenient single-dose packaging improving patient compliance.

( 03 ) Chemical and Cosmetic Powder Applications

Detergent powders and cleaning agents need consistent dosing ensuring proper cleaning performance. Dye powders require accurate measurement for color consistency in textile and craft applications.

Face mask powders and skincare formulations demand contamination-free packaging maintaining product purity. Bath powders and spa products benefit from attractive stick pack presentation supporting premium pricing.

The TL-SP-1P handles hygroscopic chemical powders requiring moisture barrier protection during storage and distribution.

Frequently Asked Questions About Powder Stick Packing Machines

( 01 ) What powder flowability characteristics work best with the TL-SP-1P?

The TL-SP-1P handles powders with good to medium flowability—materials that flow relatively freely when agitated but may not discharge smoothly under gravity alone.

Free-flowing powders like fine salt and free-flowing milk powder work excellently. Moderately cohesive powders like cocoa, protein powder, and pharmaceutical blends work well with appropriate auger selection.

Highly cohesive or sticky powders may require hopper agitation systems or specialized auger configurations. Soontact provides free sample testing to evaluate specific powder formulations before purchase.

( 02 ) How does auger screw dosing achieve better accuracy than cup dosing for powders?

Cup dosing measures volume, and powder volume varies with aeration and compaction states. The same cup captures different powder masses depending on how powder entered the cup and how long it settled.

Auger screw dosing measures powder by mechanical displacement—each auger revolution moves a predictable powder mass regardless of aeration.

Servo control adjusts rotation speed based on real-time feedback, compensating for density changes as hopper levels drop. Result: ±1% fill weight accuracy versus ±2-3% typical for cup dosing with powders.

( 03 ) How does the machine minimize dust during powder filling operations?

Three design features control dust generation: enclosed hopper with sealed lid prevents dust escape from bulk powder storage; sealed auger tube assembly contains powder during transport from hopper to filling point; controlled auger rotation releases powder gradually rather than dropping it freely.

Optional dust collection systems capture airborne particles near the filling station. Reduced dust improves seal quality, extends equipment life, and creates cleaner working environments.

Proper facility ventilation supplements machine-level dust control.
