Vibratory Tray Dispensers: Advanced Dosing for Powders & Solids
Vibratory tray dispensers (vibrodosers) deliver precise, non-degrading handling of:
Free-flowing powders (protein, spices, APIs).
Fragile granules (cereals, freeze-dried foods).
Irregular solids (nuts, candy, hardware components).
Unlike screw systems, vibration-driven transport eliminates:
✓ Particle damage ✓ Segregation ✓ Bridging/clogging
Gentle, clog-free dosing of cohesive powders and fragile granules with industry-leading ±0.25% accuracy – even for materials below 0.3 g/cm³ bulk density.
