Romberger Digestate Dryer – Efficient Substrate Reduction for Biogas Plants The Romberger digestate dryer offers an energy-efficient solution for reducing digestate volume in biogas operations. By evaporation, the liquid content is reduced by up to 50%, significantly lowering storage and transport costs. Your Benefits: - Automated operation: Integrated filling and discharge allow for continuous, low-maintenance drying - Valuable fertilizer output: Dry matter increases to up to 12%, raising nutrient concentration; combined with ammonium sulfate solution (ASL), the process yields high-quality liquid fertilizer - Dust-free process: Low dry matter content minimizes dust; exhaust air treatment complies with emission standards and reduces odors - Efficient heat utilization: Uses surplus heat from CHP units, improving energy efficiency and enabling eligibility for CHP bonuses How It Works: Heated contact plates evaporate moisture from the digestate. Exhaust air is treated via a certified cleaning system to minimize emissions. Example Calculation: With an energy input of 600 kW/h, approximately 420 liters of liquid can be evaporated per hour – that's around 3,360 m³ per year. Romberger – your partner for smart, sustainable digestate treatment.
