Rotary Steam Tube Bundle Dryer

Technip’s Rotary Steam Tube Bundle Dryer uses indirect steam heating , where steam flows inside the tubes while the product passes over the tube surfaces. The rotating shell, supported with baffles, controls the movement of material over the tubes, enabling gentle tumbling and uniform drying . The combination of slow rotation and internal baffles arrangement ensures gentle agitation , promoting rapid moisture evaporation by conduction , without direct contact between the product and heating medium. This design minimizes product degradation while maintaining consistent moisture content throughout each batch or continuous operation.

Key Advantages :-

• Minimal Product Degradation – Gentle tumbling action and precise temperature control protect sensitive materials, ensuring superior product quality and integrity.
• Automated and Reliable – Fully automatic system with low maintenance and adjustable parameters for varying feed moisture and throughput.

Energy-Efficient Operation

Extremely low steam consumption typically 10–1.20 kg of steam per kg of water evaporated using steam at 3 bar(g)

Lower OPEX

The dryer plant offers reduced operating costs compared to alternative drying technologies, resulting in lower overall OPEX while maintaining high efficiency and product quality.

Applications :-

The system is widely used across various industries, including:

Grain Based Distilleries DDGS Dryer

• Mixter of Spent Grain (Stillage) & Yeast Drying Application
• Cellulose / Lignin Drying Application
• Citrus Fruits Peel Drying Application
• Palm Oil Mill Effluent Drying Application
• Fibrous extracts Drying Application
