Product Overview: Tube Bundle Dryer is an indirect steam heated dryer and is well known for its efficient and gentle treatment of products. WORKING PRINCIPLE The steam heated tube bundle slowly rotates in a fixed housing and conveys the product to be dried axially through the dryer. Shovels transport the product along the circumference of the housing, where it falls through the heated tube bundle for each rotation. The economic and gentle drying is achieved by contact with the tubes and convection. The heat source is typically saturated steam between 4 – 10 barg, solutions with lower steam pressure are available. MAIN DESIGN FEATURES - Effective self-cleaning to minimize dead zones, product accumulation and product degradation - Excellent kneading and mixing for better homogenization - Effective heat transfer - High surface renewal efficiency - Large free vapor volume - Precise and uniform temperature control due to large heat transfer areas - Continuous or batch processing - Process intensification - Processing of sticky and highly viscous products - Residence time is independent from agitator speed, wide and flexible range of average residence times - Reliable process scale-up from pilot to industrial units - Large production capacities, economy of scale - Maximum process yield per unit volume - Reliable, robust design - Short return of investment BENEFITS - Drying only with indirect steam and sweep ambient air, means no pollution to your product. - Low installation costs through modular design and pre-manufacturing. - Gentle drying through low temperatures. - Low energy consumption in the range of 1.25 to 1.3 lbs of steam/lbs of water evaporation. - Optimal sealing and insulation secure high wet-bulb temperatures and optimize energy recovery up to 67% in further processes (e.g. evaporator). - Safe process: minimized oxygen content ensures the lowest explosion and fire risk. ATEX design if required. - Clean and environmentally friendly: Integrated dust collector to minimize dust emissions to the atmosphere – closed-loop systems are also available. - Closed gas-tight system as well as design for drying below atmospheric pressure are possible.
