The EFT Dryer evaporates the water from the waste with an inlet moisture of 80%, down to 10%, in order to reduce the mass up to 70% and the volume of the 50÷60%.
The EFT has different applications: on the wet sludge coming from the waste water treatment plant, on the wet residuals and biomass.
The machine is innovative since, unlike other Driers available on the market, the transmission of heat mainly occurs by convection and not by radiance, privileging the speed parameter compared to the drying air temperature parameter. In fact, low quality primary energy (water at 80-85°C) is used, and therefore economical and easily obtainable in cogeneration plants, with consequent advantage in running costs.
