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
