The high moisture content of biomasses such as agricultural waste, municipal solid waste and sludge has always been a limiting factor in secondary use of these materials. Thermal drying is a cost intensive and energy intensive process while conventional mechanical drying methods are often unable to reduce moisture sufficiently. As a result, drying has often been the most difficult step in any of these processes. The Dryclone™ System changes that.
Until now, expensive and time-consuming sorting of Municipal Solid Waste was needed to separate dry material from wet. The material that was already dry could be used as fuel for a variety of purposes, including Waste to Energy. The remaining wet material was not used and constituted an expense for disposal. With the RCI Dryclone™ System, this sorting is no longer needed since the Dryclone™ can dry out all the material to a uniform level of sub 15% moisture, making it excellent for a wide variety of applications.
The Dryclone™ separates the water mechanically from the feedstock using a high velocity air stream. As an additional advantage, the feedstock is reduced in particle size, increasing surface area during the process. These capabilities, coupled with high-volume throughput capacity, make the Dryclone™ System the only commercially available system of its kind.
The RCI Dryclone™ System can reduce moisture content to < 15% while reducing particle size, at a rate of up to 15 tons per hour for each twin-line System.
The Dryclone™ Technology
- Wet material is fed into an air stream and accelerated to high velocities before entering the first of several Drycones ™.
- The combination of air velocity and impact in the Dryclone™ act on the feedstock to dry it and reduce its size.
- The number of Dryclone™ will vary depending upon initial moisture, degree of drying, throughput and quality of the feedstock
