Powder Packaging Machine
A high-precision auger-driven powder packaging system designed for free-flowing to cohesive powders (bulk density: 0.3–1.2 g/cm³). Engineered for GMP-compliant environments, the system integrates servo-controlled auger filling and vertical form-fill-seal (VFFS) technology. Applications include pharmaceuticals (API powders), food additives (vitamins, spices), and industrial chemicals (TiO₂, silica).
Microprocessor-Driven Auger: Achieves ±0.25% fill accuracy (validated per NIST Handbook 44) via closed-loop feedback from high-resolution load cells (0.01g sensitivity).
Zero-Residual Discharge: Patented auger tip geometry reduces material retention to <50 mg/cycle.
Broad Powder Compatibility: Handles free-flowing (e.g., sugar, salt) to cohesive powders (e.g., titanium dioxide, protein isolates) with bulk densities of 0.3–1.2 g/cm³.
Quick-Change Tooling: Interchangeable augers (40–80mm) (<5-min swap time) for rapid product changeovers.
Continuous Operation: Rated for 24/7 duty cycles with <0.3% downtime
Auger Dosing System
This system combines pharmaceutical-grade compliance with industrial robustness, delivering ≤0.5% material waste and >99% OEE (Overall Equipment Effectiveness) in validated production runs.
Auger Design
Twin-start stainless steel auger (316L, Ra ≤0.8 µm) with anti-segregation flights.
Diameter options: 40mm, 60mm, 80mm (handling capacities: 5g–5kg per cycle).
Drive Mechanism
Servo motor (1.5 kW, 3,000 rpm) with absolute encoder (17-bit resolution).
Gearbox ratio: 10:1 (peak torque: 120 N·m).
Anti-Bridging Features
Hopper vibrator (0.3–1 bar pulsation) with PID-controlled amplitude.
Rotating paddle agitator (5–20 rpm) for cohesive powders (Hausner ratio >1.4).
