Overview
BIODRY is Strahl's series of mobile dryers for cereals, legumes and seeds that require clean, protected drying air. A stainless-steel heat exchanger keeps combustion air separate from drying air to reduce contamination risk and preserve organoleptic properties. The compact boiler reduces atmospheric emissions and thermal losses, supporting a more sustainable drying process for farms, contractors and facilities focused on quality and traceability.

Key benefits

• Clean drying air: Combustion air is kept separate from drying air and never contacts the product, meeting organic‑chain requirements.
• Energy recovery: Large stainless-steel heat exchanger maximizes thermal recovery and lowers fuel consumption for a given capacity.
• Uniform product quality: Continuous product circulation inside the dryer promotes homogeneous drying and improved shelf life.
• Shorter drying times: Large heat-exchange surface between hot air and product enables fast drying without compromising quality.

Components and functions

• Loading hopper: For product intake and preliminary separation of foreign elements.
• Central auger: Transports product upward, reintroducing it into the drying zone and aiding discharge.
• Swivel discharge: Allows gravity discharge or, on flat sites, discharge via an auger with electric motor.
• Heat exchanger: Fully separates combustion air flow from drying air flow.
• Fan: Draws external air through the preheated furnace and sends it into the drying bell to reduce moisture.
• Expulsion cleaner: Removes impurities using a drop-expulsion mechanism.
• Electrical panel (automatic/manual): Centralized control of dryer operational processes.
• Drive options (PTO and/or electric): Available PTO (cardan), electric or mixed drives depending on operational needs.
• Temperature sensors: Measure and monitor product temperature during drying.
