Rotary Tube Bundle Dryer Manufacturer

What is a Rotary Tube Bundle Dryer

Rotary Tube Bundle Dryer is one of the most effective and energy dryers. The wet feed material is fed into rotating drum, which consists of tube bundle inside it. The tubes are heated by means of steam/thermic oil flowing inside. Tube and bundle rotate at slow speed in a stationery housing in which material passes over these tubes and material gets dried by heat of conduction.

Technodry is a trusted Rotary Tube Bundle Dryer manufacturer in India, specializing in low-temperature drying systems for heat-sensitive materials such as distillery wet cake (DDGS), starch residues, chemical sludges, and protein-rich by-products. Our RTBD systems are engineered for energy efficiency, gentle drying, and continuous operation, making them ideal for industries that demand high-quality drying with minimal thermal degradation.

Pilot Trials Available
