Product overview
BIODRY is Strahl’s series of mobile indirect-fired dryers for cereals, legumes and seeds that require a clean, protected drying air stream. A stainless steel heat exchanger fully separates combustion air from drying air to minimise contamination risk and preserve organoleptic qualities. The compact, efficient boiler contains emissions and limits thermal losses, supporting more sustainable, cost-effective drying operations for farms, contractors and quality-focused facilities.

Key benefits

• Clean drying air: combustion air is kept separate from the drying air that contacts the product, suitable for organic supply chains and traceability requirements.
• Energy recovery: large stainless steel heat exchanger maximises thermal recovery and lowers fuel consumption per unit capacity.
• Uniform product quality: continuous internal recirculation promotes homogeneous drying and improved shelf life.
• Reduced drying time: extensive heat exchange surface enables faster moisture removal without compromising product quality.

Technical components (visualizer)

• Loading hopper: receives and feeds the product, allowing separation of unwanted elements.
• Central auger: conveys product upward and reintroduces it into the drying zone, aiding discharge.
• Swivel discharge: allows gravity discharge or, on flat sites, auger discharge driven by an electric motor.
• Heat exchanger: stainless steel unit that keeps combustion and drying air streams fully separate.
• Fan: draws ambient air, channels it through the preheated furnace and into the drying bell to reduce product moisture.
• Expulsion cleaner: removes impurities using a drop/expulsion mechanism.
• Electrical panel (automatic/manual): centralized control of dryer processes and modes.
• Drive options (PTO and/or electric): available as PTO (cardan), electric or mixed drive depending on operational needs.
• Temperature sensors: monitor product temperature throughout the drying cycle.
