Pneumatic Vacuum Conveyor Solution for Food Granules Handling

Product introduction of Pneumatic Vacuum Conveyor

Pneumatic vacuum conveyor is an advanced enclosed material handling system that uses vacuum negative pressure to efficiently transport powders, granules, flakes, and fine particles. It enables direct feeding into mixers, hoppers, reactors, packaging machines, and other processing equipment. The system operates through a vacuum generator, conveying pipeline, and filtration unit, ensuring stable and continuous material transfer without dust leakage or contamination. Constructed from polished stainless steel 304, it meets GMP hygiene standards for food, pharmaceutical, chemical, and plastic industries. With automatic pulse backflush cleaning, low noise operation, and energy-efficient design, it significantly reduces manual labor, improves production automation, and ensures safe, reliable, and high-capacity material conveying performance in modern industrial environments.

Working principle

Step 1: Vacuum Generation
Compressed air drives the vacuum generator to create negative pressure.

Step 2: Material Suction
Material is drawn from storage containers into the suction inlet.

Step 3: Pipeline Transport
Negative pressure airflow carries materials through sealed pipelines.

Step 4: Separation Process
Air and material are separated in the filter chamber or cyclone unit.

Step 5: Material Collection
Powders and granules fall into the receiving hopper or silo.

Step 6: Automatic Discharge
Discharge valve opens and material flows into target equipment.

Step 7: Filter Cleaning
Automatic pulse backflush cleans the filter element for next cycle.
