Cereal dryer BIODRY ES 2550

seedpaddy ricemobile

Overview
BIODRY is Strahl's series of mobile dryers for cereals, legumes and seeds that require clean, protected drying air, suitable for organic supply chains and operations focused on quality and traceability. An indirect combustion system with a stainless‑steel heat exchanger keeps combustion air separate from drying air, minimizing contamination risk and preserving organoleptic properties. The compact boiler and large exchanger reduce emissions and thermal losses while maximising thermal recovery, making the drying process more sustainable and cost‑effective for farms, contractors and processing facilities.

Key Benefits

• Clean drying air: Combustion air is fully separated from the drying air that contacts the product, meeting requirements for organic production.
• Energy recovery: Large stainless‑steel heat exchanger maximises thermal recovery and reduces fuel consumption at equivalent capacity.
• Uniform product quality: Continuous product movement inside the dryer promotes homogeneous drying and improves shelf life.
• Faster cycles: Design provides a large exchange surface between hot air and product for reduced drying times without compromising quality.

Main Components and Functions

• Loading hopper: Allows loading of the material to be dried and separation of unwanted elements.
• Central auger: Transports product upward and reintroduces it into the drying zone, facilitating discharge.
• Swivel discharge: Dried grain can be discharged by gravity or via an electrically driven auger when no slope is available.
• Heat exchanger: Keeps combustion air and drying air completely separate.
• Fan: Draws external air, channels it through the preheated furnace and sends it into the drum to reduce moisture.
• Expulsion cleaner: Removes impurities using a drop expulsion mechanism.
• Electrical panel (automatic/manual): Centralised control of dryer operations.
• Drive options: PTO (cardan), electric or mixed drives available according to operational needs.
• Temperature sensors: Measure and monitor product temperature during drying.
