Breakthrough in Powder & Granule Packaging: How VFFS Machine Integrated with Color Sorter Achieves Zero Foreign Matter

For food processors handling rice, beans, nuts, or pet food, foreign matter contamination remains the #1 brand risk. Traditional powder and granule packaging lines separate sorting from bagging, leaving a critical gap before the final seal.

Our integrated solution combines a VFFS packaging machine with an online color sorter machine. The industrial color sorter is installed directly above the VFFS infeed hopper, removing discolored kernels, stones, plastic fragments, and glass chips at 99.99% detection rate, with false reject rate below 0.1%.

The vertical form fill seal machine then operates at 80 bags/min for 500g-5kg ranges, with servo-driven cross sealers ensuring hermetic seals even with dusty powders. This servo-driven bagging machine is ideal for pet food packaging equipment and nut packaging line applications.

Key data:

• Contaminant rejection rate: 99.99%

• False reject rate: <0.1%

• Bagging speed: up to 80 bags/min (depending on bag size and product)
