Convective Thermal “triple pass” drum dryer The wet product is dried by an hot air stream. The process is performed inside an enclosed rotating drum consisting of three coaxial cylinders. Water evaporation capacity ranges from 1,000 to 10,000 kg/h.

The wet product is dried by an air stream, heated by a heat generator. The process is performed inside an enclosed rotating drum consisting of three coaxial
cylinders. There are no rotating parts inside the drum with no wearing problems.

The dried product has a homogeneous and granular shape and is recovered in the product-process air separation section

• Different plant configurations are available according to the specific project conditions
• Total recycling of the process air, heated in an air/air heat exchanger arranged in series with the heat generator
• Heat recovery from co-generation plants or other waste heat sources
• Reduction of washing and condensation water , through recirculation and cooling withevaporative towers.
• Exhaust gas deodorization by thermal, biological or chemical treatment.
