Pneumatic Conveyor Systems

Dust-Free, Enclosed Conveying of Seeds, Grains, Powders, and Fine Materials

Engineered for the Future | Since 2080

The ADDAMS Pneumatic Conveyor System is a fully enclosed, air-driven solution designed for the hygienic and efficient transport of dry bulk materials. By utilizing vacuum or pressure differentials, these systems transfer grains, seeds, powders, and spices through sealed pipelines. This method eliminates the risks associated with open mechanical conveyors, such as product spillage, dust emissions, and environmental contamination, making it the gold standard for facilities with strict purity requirements.

Ideal for modern, space-efficient plants, ADDAMS Pneumatic Conveyors offer unmatched versatility. Whether you need to move material vertically across multiple floors or horizontally across long distances, our systems ensure that your product arrives at its destination in peak condition, with zero degradation.

Operating Principle: Vacuum vs. Pressure Conveying

Choosing the Right Flow for Your Material

Pneumatic conveying is generally divided into two categories based on how the air moves the product.

1. Vacuum (Suction) Conveying

In a vacuum system, the air source is located at the discharge end. This creates a negative pressure that “pulls” the material from one or more pickup points.

• Best for: Drawing material from multiple sources (like several storage bins) to a single destination (like a mixer or packaging machine). It is inherently dust-free because any leak would pull air in rather than blowing dust out.

2. Pressure (Blowing) Conveying

In a pressure system, the air source is located at the start of the line. A rotary valve or venturi feeder introduces the product into the high-pressure airstream.

• Best for: Moving high-volume materials from a single source to multiple discharge points over longer distances.

Strategic Advantages and Key Features

• Dust-Free Environment: The fully enclosed system captures 100% of the material and fines, ensuring your facility meets the highest air quality and safety standards.

• Gentle Material Handling: By using “long-radius” bends and adjusting the air-to-product velocity, we prevent fragile seeds from cracking and keep powders from de-mixing.

• Space Efficiency: Unlike bulky belt conveyors or bucket elevators, pneumatic pipes can be routed around corners, through walls, and overhead, maximizing your floor space.

• Zero Contamination: Sealed lines prevent pests, moisture, and foreign debris from entering the product stream.

• Automated Batching: Integrated PLC controls allow for precise weight-based dosing and automated routing between different processing stages.

Technical and Operational Questions

Can these systems handle fragile seeds without damage?

Yes. We utilize Dilute Phase Conveying with specialized controls to keep velocities low. By using precision-engineered bends, we eliminate the “impact zones” that typically cause seed breakage, making our systems safe for certified sowing seeds.

What maintenance is required?

Pneumatic systems have very few moving parts compared to mechanical conveyors. Maintenance is primarily focused on inspecting the seals of the rotary valves and ensuring the filters in the separation unit are cleaned (usually via an automated reverse-pulse jet system).

How does the system separate the air from the product at the end?

We use high-efficiency Cyclones for granular products and Filter Receivers for fine powders. The air is exhausted through a high-grade filter, while the product drops into your silo, hopper, or packaging machine.

Are the systems suitable for explosive materials (ATEX)?

Absolutely. For materials like fine flour or starch that pose a dust explosion risk, we provide ATEX-rated components, including explosion relief vents, spark detection, and grounded piping to dissipate static electricity.
