Can the same packaging machine handle both powder and granular products?
• Usually not interchangeable: powder needs dust control and auger/vacuum dosing, granules need volumetric/weighing dosing.
• On auger-dosing machines, granules require a vibratory hopper and changed screw, or bridging and granule breakage occur.
• Powder demands high dust extraction and sealing integrity; granules demand smooth flow, so two feeding sets and heat-seal recipes are needed.
• Decision criterion: confirm the supplier offers both powder and granular dosing modules with changeover time ≤30 minutes.
• Require FAT with powder and granules separately, verifying dosing accuracy ±1% and clean heat-seal without powder trapped.
