Industrial Applications

Flour Pneumatic Conveying Line
Conveys milled flour directly from sifter outlets into pneumatic transport lines using blow-through air, reducing equipment footprint and potential contamination points.
Dairy Powder In-line Transfer
Provides hygienic blow-through feeding of milk powder and whey protein from spray dryer outlets into packaging line conveying systems.
Spice Powder Direct Conveying
Injects ground spice powders directly into pneumatic conveying lines with full pocket purging, preventing cross-contamination between spice varieties.
