Commerical Dryer

Biomass and various wastes (e.g. municipal solid wastes) can have very high moisture contents, sometimes more than 50%. As a general rule, when it comes to effective, efficient pyrolysis, the higher the moisture content, the longer the process takes and the more energy used. After being unsatisfied with the performance trialling many existing commercial dryers, Renergi decided to design, build, commission, and patent our own cutting-edge technology. Crucially this technology is integrated with our Grinding Pyrolysis technology and forms part of the overall plant completed in Collie, Western Australia and makes the ‘waste to energy’ not only possible but commercially viable.

Renergi’s patented drying technology uses low-grade/low-temperature heat as the source of energy for drying, significantly reducing the energy intensity compared to other commercial dryers. A key feature of this drying technology is the avoidance of the direct contact of biomass with a hot stream of flue gas, eliminating the danger of a fire or explosion which are major risks in many conventional direct-contact drying technologies. The innovative design creates a huge heat transfer surface area, achieving very high drying rates with well-controlled temperatures while the highly innovative design minimises energy usage across all aspects of its operational process.

Renergi’s drying technology also eliminates the emission of volatile organic compounds and pathogens commonly contained in wet wastes (e.g. bacteria and viruses in municipal solid wastes).

Renergi’s highly innovative and low energy intensity drying technology can be used for much more than the drying of biomass and wastes, for example, the drying of foods, chemicals and minerals.
