👉 Pressure conveying is the right choice for long-distance and high-capacity transfer of powders and granules. Unlike vacuum systems that pull material, pressure systems push material with compressed air, making them ideal for bulk movement from silos to storage, processing, or bagging units.

Dilute Phase Pressure Conveying System
Dilute Phase Pressure Conveying System
High-Throughput, Long-Distance Powder & Granule Transfer
Orchid’s Dilute Phase Pressure Conveying Systems are engineered for continuous and large-volume transfer of powders and granules using positive pressure air streams. Unlike vacuum systems designed for short to medium distances, pressure conveying is best suited for long pipelines, high capacities, and heavy-duty industrial applications.
Working Principle
The system uses roots blower pressure to push materials through pipelines at high velocity. Material is fed from silos, bag dump stations, or hoppers into the line and transported to distant receiving vessels. With airlocks, blowers, and filtration units, the system ensures smooth, uninterrupted flow across long distances while keeping the conveying line sealed and dust-free.
Key Features
- Long-Distance Conveying – Capable of transporting materials up to several hundred meters.
- High Throughput – Designed for continuous operation at large capacities.
- Robust & Reliable – Built for demanding industrial environments.
- Flexible Integration – Works with silos, big bag unloaders, storage vessels, and bagging lines.
- Multi-Discharge Capability – Can deliver to multiple destinations within a plant.
- Flameproof Zone Ready – Safe operation in controlled plant environments.
Applications Across Industries
- Pharmaceuticals & Nutraceuticals → Large-scale excipient transfer to blending or granulation.
- Chemicals & Petrochemicals → High-volume conveying of additives, powders, and catalysts.
- Food & Spices → Bulk transfer of flour, starch, grains, and sugar to silos or packing lines.
- Brewery & Distilleries → Continuous feeding of malt, starch, and brewing ingredients.
- Plastics & Polymers → Long-distance transfer of resins, pigments, and plastic granules.
- Paints & Dyes → Conveying pigments and fillers for continuous production.
- Power & Energy → Reliable bulk transfer of biomass and fly ash.

❓ Final FAQ – Dilute Phase Pressure Conveying System
-
1. When should I choose pressure conveying instead of vacuum conveying?
-
2. Can pressure conveying systems handle multiple discharge points?
👉 Yes . With diverter valves and distribution lines, the system can be designed to deliver material to multiple destinations, such as hoppers, silos, mixers, or packaging lines. This makes it highly flexible for plant-wide material distribution.
-
3. Which industries use pressure conveying the most?
👉 Pressure conveying is widely applied where bulk powders must be transferred over long distances, such as:
- Food & Spices → Bulk flour, starch, and sugar conveying to silos
- Plastics & Polymers → Resin and pigment transfer to storage or process units
- Power & Energy → Fly ash, biomass powder transfer in utility plants
- Chemicals & Petrochemicals → Additives, catalysts, and fine powders at scale
-
4. Is it safe for sensitive or controlled plant environments?
👉 Yes . Orchid designs pressure conveying systems with flameproof compliance for controlled plant zones. For food and pharma bulk handling, stainless-steel builds with hygienic finishes are available to meet regulatory standards.
-
5. How much maintenance do these systems require?
👉 Very little. With robust blowers, rotary airlocks, and advanced filter units, pressure systems are built for continuous duty. Preventive checks on air supply, pipelines, and filters ensure long service life and reliable operation.
