Description
Gratt steam dryers are designed for drying sanitary and industrial waste, as well as various animal and plant by-products. After dehydration, the material can be used for thermal energy generation, organic fertilizers, or animal feed.
The system includes a reception hopper, screw conveyors for feeding and extraction, an exhaust system for gas removal, a cyclone for fine separation, and an absorption tower for gas washing. The layout is customized according to the client's plant.
The dryer features a circular structure with one or two rotating shafts equipped with heating tubes. The indirect steam heating system (6 to 10 bar) ensures efficient drying without direct contact between the product and the heat transfer fluid. A scraping system prevents material buildup, optimizing performance and longevity.
