Technip EST Pvt. Ltd.’s Rotary Screw Conveyor Dryer is a versatile, robust solution for thermal drying of wet solids, slurries, granules, and powders, offering efficient moisture removal and consistent product quality across process, ZLD, chemical, food, and mineral industries.
Screw Conveyor Mechanism: Material is continuously moved through a heated cylindrical drum by a rotating helical screw blade, which ensures thorough mixing and exposure to the heating medium (steam, hot air, or water). The screw’s design can be tailored for feed properties, throughput, and desired final moisture.
Indirect or Direct Heating: Depending on application, dryers may use direct heating (hot air/steam injection) or indirect heating via a jacketed shell, allowing safe and effective drying of sensitive, hazardous, or abrasive materials.
Continuous, Controlled Drying: Material residence time and temperature profiles are carefully managed with variable screw speed, ensuring complete moisture removal for optimal product consistency.
High Thermal Efficiency: Maximizes heat transfer via conduction, convection, and radiation; recyclable energy systems can further reduce consumption.
Handles Diverse Materials: Capable of drying bulk solids, filter cakes, granules, crystals, slurries, and wastewater sludge, suitable for chemical, food, pharma, minerals, and ZLD streams.
Low Maintenance, Simple Design: Few moving parts, sturdy construction, and easy access for cleaning and preventive maintenance, translating to reduced downtime and operating costs.
Automated Operation: Integrates with plant controls for precise moisture, temperature, and feed management, supporting continuous, large-scale drying needs.
Flexible Scaling: Can be customized for capacity (hundreds to thousands of kg/hr), temperature profiles, and material characteristics.
Rotary screw conveyor dryers are deployed in ZLD plants for sludge drying, food industries for bulk powder production, minerals for dewatering, chemicals/pharma for granulation, and wastewater treatment for moisture removal and volume reduction.
Technip EST Pvt. Ltd.’s rotary screw conveyor dryer solutions ensure reliable, energy-efficient drying for varied industrial needs, supporting sustainable production and waste minimization goals.
