Air Drying Systems

The high moisture content of residual sludges and organic waste is a barrier to cost-effective disposal or reuse. The biggest challenge is the moisture trapped inside the cell structure of organic materials. Conventional dryers can’t open the cell structure and remove the moisture inside.

Applications: agricultural waste dryer, anaerobic digester sludge dryer, biomass dryer, dryer, energy from waste, food waste dryer, landfill diversion, landfill, municipal waste dryer, refuse derived fuel, solid recovered fuel

The Dryclone Air Drying System from RCI solves this problem using only air to convey, pulverize and efficiently remove the moisture from residual sludges and organic waste in a cost-effective way. Dryclone’s aerodynamic pulverization means it can remove the moisture trapped inside the cells of organic materials, unlike conventional dryers, drum dryers, ring dryers, and fluidized bed dryers. This can create new opportunities for massive savings in transportation and disposal costs, and profit from saleable products.

Dryclone can dry feedstocks from up to 85% moisture content to less than 15%.* This results in weight reduction of up to 75%, drastically reducing your transportation and disposal costs. And thanks to the aerodynamic pulverization, Dryclone also creates the opportunity to produce energy or nutrient products.

The Dryclone uses huge quantities of air moving at very high speeds combined with sophisticated aerodynamic design to convey, pulverize and dry the wet waste. The cleverly managed air flow inside the Dryclone causes the feedstock to impact on itself, not against the internal surfaces, preventing wear. The material-on-material impaction shears open the cell structure and removes the moisture inside. As a result, the material is evenly and consistently dry, not dry on the outside and wet in the middle.

The Dryclone has no moving parts in the pathway of the feedstock between the infeed and outlet airlocks. This results in long-term reliability and low operating costs. The Dryclone is self-contained and doesn’t require an external heat source to operate. The natural heat of the compression of the blowers warms the air sufficiently to achieve maximum drying efficiency in any climate.

However, the Dryclone’s built-in heat exchangers mean that you can take maximum advantage of locally available waste heat without modification to further reduce energy costs.
