Safe and gentle pneumatic conveying of bulk materials using intelligent technology and optimized piping systems.
material transport for bulk material
Pneumatic Conveying
Whether for feeding production machines with raw materials, transporting intermediate products, or centralizing the collection of end products, pneumatic conveying enables the gentle, safe, and efficient transport of bulk materials. Riedel Filtertechnik’s pneumatic conveying systems provide application-specific solutions for suction conveying with a particular focus on maintaining product quality and ensuring production stability.
Our patented SACU tobtronic® is the most effective and safest technology to ensure pneumatic transport at low speed levels without blockages. The patented FPC pipe couplings prevent gaps and edges that could affect the bulk material. Remaining fine dust in the transport air is reliably removed by our dust extraction systems, allowing the air to be reused or discharged outside.
Advantages
material transport using pneumatic conveying
Pneumatic conveying of bulk materials offers several advantages compared to mechanical conveying methods such as conveyor belts, chain conveyors, or bucket elevators. It is suitable for many applications, including the pneumatic transport of powders, granules, pallets, or dust. Here are the main benefits of pneumatic conveying systems for bulk materials:
- Safety through Closed Systems: Pneumatic conveying systems are inherently closed. This prevents the escape of dust or bulk materials, resulting in a clean and safe working environment.
- Material Efficiency through Gentle Conveying: Pneumatic conveying allows for gentle material transport when properly designed and controlled. This is especially important for sensitive materials, as it helps maintain high product quality while maximizing material efficiency and production yield.
- Hygienic Benefits: Because the pneumatic conveying system is closed, the risk of contamination of bulk materials by dust and moisture is minimized. This is particularly crucial in the food and pharmaceutical industries.
- Low Maintenance Requirements: Compared to mechanical conveying systems, pneumatic conveying systems have fewer moving parts, such as bearings, chains, or gears. This reduces wear, maintenance needs, and the risk of production downtime.
- Flexibility and Modularity: Pneumatic conveying systems can be used flexibly in horizontal, vertical, and long-distance applications of up to 250 meters. This allows for a streamlined system design with high adaptability to specific conditions and production processes.
- High Conveying Speed: Pneumatic conveying enables fast and efficient movement of materials. This can increase production speed and efficiency while maintaining consistent material quality.
- Reduced Energy Consumption: Pneumatic conveying allows for demand-based and dynamic transport of bulk materials, especially when combined with smart transport control. This can achieve improved energy efficiency, particularly in conveying over longer distances and heights.
- Clean Material Separation: When switching materials, prior pneumatic cleaning of the piping systems ensures a clean separation of goods. Pneumatic conveying systems thus have a significant advantage over mechanical systems, such as bucket elevators, where complete material separation is more difficult to achieve.
Innovative Features
Pneumatic conveying systems by Riedel Filtertechnik
Riedel Filtertechnik relies on pneumatic transport of bulk materials using suction conveying, also known as vacuum conveying. In this process, materials are transported pneumatically through airflow under vacuum. At transport speeds of around 15 to 20 m/s, the material is conveyed gently over transport pipelines using air conveying.
We specialize in application-specific and customized pneumatic conveying systems that ensure high material, production, and energy efficiency, as well as minimal material degradation through the use of patented technologies and smart controls. The following features are incorporated into Riedel Filtertechnik's pneumatic conveying systems:
DYNAMIC TRANSPORT CONTROL WITH SACU TOBTRONIC®
Integration of sensors and measurement points within the transport pipelines for measuring and intelligently regulating transport speed and conveying volume. Additional features and safety systems, such as leak detection and Priority Mode, ensure the desired transport quantities.

Applications
of pneumatic conveying systems
When handling certain bulk materials, due to the nature of the material and industry-specific production processes, pneumatic conveying technology is clearly preferable to alternative mechanical conveying systems. This is particularly true for granulates and pellets, as well as lightweight bulk materials that are sensitive to mechanical damage.
Design
of Pneumatic Conveying Systems
When designing pneumatic conveying systems correctly, a variety of factors must be considered. Material properties, production conditions, and customer requirements need to be analyzed and balanced. These factors influence the optimal design of pipe systems and fans, conveying speed, and the implementation of the pneumatic conveying system's control. In designing our suction conveying systems, we draw on profound technical knowledge and decades of experience.
- Material properties
- Material Characteristics: Bulk materials vary in particle size, shape, and hardness. These properties determine whether a bulk material is suitable for pneumatic suction conveying and what conveying parameters should be selected.
- Abrasion: Highly abrasive materials cause greater wear on the pipe systems, especially at pipe bends. This should be taken into account particularly in relation to conveying speed and the design of the pipe systems.
- Moisture: Moist materials tend to clump together, which can obstruct material flow and potentially lead to blockages in the pipe systems if the conveying speed is too low, causing system downtime.
- Material Characteristics: Bulk materials vary in particle size, shape, and hardness. These properties determine whether a bulk material is suitable for pneumatic suction conveying and what conveying parameters should be selected.
- Production conditions
- Throughput: Both during material intake and when transferring material to production machines, there can be planned and unplanned fluctuations in the throughput. Smart automation can adjust the material conveying to accommodate these conditions.
- Production Cycles: Changing materials require dynamic adjustments to system parameters and the ability to clean the pipe systems easily and effectively to avoid contamination during pneumatic conveying.
- Transport Routes: Depending on the length of the transport routes and the heights to be overcome, piping should be designed as optimally as possible. To minimize energy consumption, material degradation, and wear during suction conveying, steep bends and long conveying distances should be avoided whenever possible.
