Product overview
BIODRY is Strahl’s range of mobile dryers for cereals, legumes and seeds that require clean, protected drying air. The stainless‑steel heat exchanger keeps combustion air fully separate from the drying air in contact with the product, reducing contamination risk and preserving organoleptic properties. A compact, efficient boiler and optimized thermal recovery limit emissions and heat losses, supporting sustainable, cost‑effective drying for farms, contractors and processing facilities.

Key benefits

• Clean drying air: combustion air remains isolated from drying air that contacts the product, meeting requirements of organic supply chains.
• Energy efficiency: oversized heat exchanger maximizes thermal recovery and reduces fuel consumption at comparable capacity.
• Product homogeneity: continuous internal movement ensures uniform drying and improved shelf life.
• Reduced drying time: large exchange surface between hot air and product enables fast drying without compromising quality.

Main components and functions

• Loading hopper — receives product and enables separation of unwanted materials.
• Central auger — conveys product upward and reintroduces it into the drying zone, aiding discharge.
• Swivel discharge — allows gravity discharge or auger discharge with electric motor.
• Heat exchanger — stainless‑steel unit separating combustion air and drying air flows.
• Fan — draws external air, channels it through the preheated furnace and into the drying bell.
• Expulsion cleaner — removes impurities via a drop‑expulsion mechanism.
• Electrical panel (automatic/manual) — centralized control of dryer processes.
• Drive options (PTO and/or electric) — available with PTO, electric or mixed drive.
• Temperature sensors — monitor product temperature during drying.
