Sugar
Markets
The production and handling of crystal sugar creates dust – for example during drying, at the sieving and packing station or at transfer points in transport. We can apply solutions and equipment at all of these places. Riedel Filtertechnik has been an established partner to the sugar industry for decades. Our profound process expertise makes us more than simply an equipment supplier: We are a solution partner on issues of sugar conditioning and silo dedusting. Together with our customers, we develop individual concepts for their process dedusting and for sugar conditioning. To permanently guarantee the quality of ready-for-sale sugar, sugar conditioning is crucial. We supply our customers’ conditioning and storage silos with air of a regulated quality and ensure it is distributed as well as possible. The result? Consistent sugar quality. In addition: Since sugar dust is explosive, the safety of humans and machines is of utmost importance during its removal. Explosion protection measures are an integral part of systems. In addition, the recovery of sugar from the process exhaust air contributes to increasing the yield. This means our partners from the sugar industry benefit twice in terms of sugar conditioning and silo dedusting.

Products
- Silo conditioning
We keep your sugar free-flowing - thanks to optimal conditioning and storage conditions. Even when sugar is dried and cooled, residual moisture remains in the crystals. The consequence? Lumps can form. We can minimize this risk - with the help of our silo conditioning system: We condition the sugar to defined process parameters using air of controlled quality. The conditioning air is extracted, dedusted and returned to the process.
- Fabric filter
Our filter systems minimize dust emissions. With our dedusting solutions, we can achieve clean gas dust contents below 1.0 mg/m³ as standard. This means that in many cases the air can be fed back into production. The result: dust emissions are reduced and the environment is protected. Our hose filters, cartridge filters and bag filters are automatically cleaned with compressed air and are also available in stainless steel, pressure shock resistant, with trace heating and insulation as well as fire and explosion protection.
- Venturi & absorption scrubber
Your exhaust streams are moist and contaminated with gases? Our scrubbers ensure safe and efficient cleaning because they reliably remove dust from moist exhaust streams. With reasonable energy input, clean gas dust contents < 5.0 mg/m³ can be achieved. The scrubbing liquid is cleaned by automatic belt filters or timer-controlled drain valves that automatically drain a partial volume during operation. The absorption scrubbers reduce acidic and basic as well as gas-laden components in the exhaust air to the permissible values.
- Pneumatic transport
Bulk materials, such as cut tobacco, tea, chips or crystal sugar, are gently transported with our pneumatic transport systems to reduce product changes to a minimum. Our patented SACU tobtronic® is the most effective and safest technology to ensure transport at a low speed level without blockages. To avoid gaps and edges, our patented FPC pipe couplings are used.
- Central machine and plant cleaning NetVac®
Our machine and plant cleaning improves the working conditions of your employees, increases plant availability and reduces wear. Central cleaning systems are more efficient than mobile equipment, such as vacuum cleaners. They ensure that dust, bulk material and production residues are collected at a central location. This makes disposal much easier. The number of cleaning points installed is virtually unlimited and can be flexibly expanded.
- Central dust and material handling DCS
Central handling of bulk materials reduces costs, increases efficiency and enhances the cleanliness of machines, plants, and buildings. The consolidation of bulk materials, dusts or products at central positions is ensured by our DCS systems. In suction mode, the bulk material is automatically picked up from the receiving points and can be transported over long distances. At the receiving point, the product is fed to the further processing procedure, loaded or compacted for disposal.
