    Dilute Phase Vacuum Conveying System

    Flexible, Clean & Reliable Powder Transfer Over Distances

    Orchid’s Dilute Phase Vacuum Conveying Systems are designed for continuous and dust-free conveying of powders and granules using negative pressure. Unlike compact powder transfer systems meant for batch operations, this solution is ideal for medium-distance transfer, multi-point feeding, and flexible routing through pipelines.

    Working Principle

    The system maintains a vacuum inside the conveying pipeline. As material is introduced from hoppers, bag dump stations, or silos, the air stream carries it at high velocity toward a receiving vessel. At the receiver, a filter system separates the material from the air before discharging it into the next process step.

    👉 Because of the negative pressure, any leakage draws air inward — ensuring dust-free and safe operation.

    Key Features

    •  Continuous Conveying – Reliable medium-distance transfer up to 100m.
    •  Flexible Layouts – Works with bends, vertical lifts, and space-restricted plants.
    •  Multi-Point Feeding – Can collect from multiple sources into one receiver.
    •  Dust-Free Operation – Closed pipeline prevents contamination and spillage.
    •  Low Maintenance – Minimal moving parts, long-life filters, and easy cleaning.
    •  Hygienic Design – Stainless-steel construction with CIP/SIP options.
    •  Safe for Flameproof Zones – Engineered for compliance in controlled environments.

    Applications Across Industries

    •  Pharmaceuticals & Nutraceuticals → Transfer of excipients, nutraceutical powders, and formulation blends.
    •  Chemicals & Petrochemicals → Conveying additives, catalysts, and fine specialty powders.
    •  Food & Spices → Hygienic movement of sugar, starch, flour, cocoa, and spice blends.
    •  Brewery & Distilleries → Handling of malt, starch, and fermentation ingredients.
    •  Plastics & Polymers → Transport of pigments, resins, masterbatch powders, and small granules.
    •  Paints & Dyes → Dust-controlled handling of pigments and fillers.
    •  Power & Energy → Conveying of biomass powders and fly ash.

    ❓ Final FAQ – Dilute Phase Vacuum Conveying System

    • 1. What is a Dilute Phase Vacuum Conveying System?

      👉 It is a continuous negative-pressure conveying system that moves powders and granules over short to medium distances. By maintaining vacuum inside the pipeline, it ensures dust-free transfer, operator safety, and reliable performance.

    • 2. How is vacuum conveying different from pressure conveying?

      👉 Vacuum conveying is best for shorter distances, flexible layouts, and dust control at feed points since air always flows inward during leaks.
      👉 Pressure conveying is preferred for longer distances and higher capacities.

    • 3. Can the system handle multiple feed or discharge points?

      👉 Yes . A dilute phase vacuum system can be designed to draw material from several bag dump stations, silos, or hoppers and deliver it to a single receiving vessel — reducing manual handling and improving efficiency.

    • 4. Is it suitable for food and pharmaceutical powders?

      👉 Absolutely. With stainless-steel construction, CIP/SIP options, and closed conveying lines, the system is ideal for clean environments. It can also be supplied with flameproof compliance for regulated plant zones.

    • 5. What about maintenance requirements?

      👉 Maintenance is minimal since the system has very few moving parts. Filters are equipped with pulse-jet cleaning or can be supplied with HEPA options, ensuring reliable operation and long filter life.
