Granule packing machine with volumetric cup filler
A gravity-fed vertical form-fill-seal (VFFS) machine engineered for granular materials (0.5–10 mm particle size, bulk density 300–1,200 kg/m³). Utilizes volumetric cups for ±0.5%~1% dosing accuracy. Suitable for free-flowing powders, seeds, fertilizers, and pharmaceutical granules.
Precision Dosing Enhancements: Micro-Adjustment Cup Mechanism Fine-threaded cup height adjuster enables ±0.1 mL volumetric tuning for irregular granules (e.g., rice grains, polymer pellets).
Precision Tolerances: Cup-bore clearance ≤20 μm. Film registration accuracy ±0.2 mm.
Robust Structural Design: Monolithic Frame Construction in Stress-relieved cast iron base (Grade HT250, ASTM A48) with vibration-damping pads (Shore 80A) reduces harmonic resonance at >90% load.
Ergonomic Serviceability: Mirror-Finished Surfaces by #8 stainless steel polish on all product-contact areas allows CIP (Clean-in-Place).
