Vacuum Conveyor - Intermittent
Product Highlights
Dust-tight closed-loop transfer with simple operation, automatic intermittent cycling, compact footprint, easy cleaning, and zero dust leakage.
Application Scope
Widely used for batch feeding and conveying of powders and granular raw materials in the food, pharmaceutical, chemical, plastic, and feed industries.
Suitable Materials
Powdered medicine, flour, food coloring, plastic pellets, calcium carbonate, feed pellets, various fine chemical powders
How it works
Uses negative pressure vacuum suction to perform intermittent cycling for material intake and discharge. The fan generates negative pressure to draw material into the hopper; once the preset level is reached, airflow automatically cuts off for discharge. After discharge completes, suction resumes. The entire process remains sealed and dust-free with intermittent cycling, featuring a simple structure that is easy to clean.
Use Cases
Proven across multiple industries and material scenarios.

Building Materials Industry
Achieve dust-free bulk material transfer to reduce workshop pollution. Automated feeding saves labor, prevents material loss from airborne powder, and integrates with mixing and stirring equipment for stable, continuous supply.

Environmental Industry
Sealed transport and eco-friendly processing of materials to suppress dust and protect operators from corrosive chemicals. Automatically dispense desulfurization, denitrification, and water treatment agents with precision, integrated with waste gas and wastewater treatment systems for fully automated chemical dosing.

Food Industry
Suitable for: dry, free-flowing, loose powders / granules

Healthcare Industry
The vacuum conveyor enables automated, no-open-lid feeding of pharmaceutical powders and granules. It transfers materials via sealed negative pressure to reactors, mixers, granulators, and tablet press hoppers. This system effectively controls dust, prevents moisture absorption and oxidation, eliminates personnel contact with toxic raw materials, meets GMP cleanroom production standards, and removes cross-contamination risks associated with manual feeding.

Chemical Industry
The vacuum conveyor transports chemical powders in a sealed, negative-pressure system, eliminating airborne dust and improving workshop air quality. Automated feeding reduces manual handling, lowering occupational health risks from powder exposure. Closed-loop transport minimizes contact with ambient air, preventing moisture absorption and contamination to ensure raw material purity. It integrates seamlessly with mixers, reactors, extruders, and other equipment for automated supply, enhancing production line continuity while reducing material loss—meeting the explosion-proof and cleanroom requirements of the chemical industry.

Mining
Dust-free conveying of fine mineral powders to reduce airborne dust, improve workplace conditions, and enable long-distance automated transport. Minimizes manual handling, reduces workers' exposure to heavy metal dust, and supplies feed for screening and grinding equipment.

Feed industry
Automatically convey feed raw materials to reduce manual handling. Enclosed conveying prevents dust from powder, ingredient stratification, and moisture absorption or clumping, ensuring precise mixing ratios and enabling continuous feeding for integrated mixing systems.
