Pilot Scale 316SS Centrifugal Spray Dryer with 5-50 kg/h Capacity and Compact 1.6 m Footprint

The Pilot Scale 316SS Centrifugal Spray Dryer is purpose-engineered to bridge the critical gap between laboratory experimentation and full-scale industrial production. With a flexible water evaporation capacity ranging from 5 to 50 kilograms per hour, this system provides the ideal platform for process development, scale-up validation, clinical trial material production, and small-batch commercial manufacturing. The 316SS stainless steel construction ensures broad chemical compatibility, making it suitable for everything from pharmaceutical intermediates to advanced ceramic precursors and specialty chemical formulations.

Constructed entirely from 316SS stainless steel for all product-contact surfaces, this pilot spray dryer offers superior corrosion resistance compared to standard 304SS equipment. The molybdenum content in 316SS provides enhanced protection against pitting and crevice corrosion from chlorides, acidic solutions, and aggressive organic solvents. This material selection is particularly critical for pharmaceutical applications involving hydrochloride salt forms, ceramic processing with acidic binder systems, and chemical manufacturing with corrosive intermediates. The vessel interior is polished to a pharmaceutical-grade surface finish, eliminating microscopic crevices where product residues or contaminants could accumulate.

The compact footprint of 1.6 by 9.1 by 1.75 meters makes this pilot system accessible for installation in standard-height pilot plant facilities without requiring specialized building modifications. Despite its compact dimensions, the drying tower provides sufficient residence time for complete moisture removal across the full 5 to 50 kg/h operating range. The tower and cyclone assembly are designed for rapid disassembly and cleaning, with tri-clamp sanitary connections throughout the product path enabling complete system turnaround in under 90 minutes between different product campaigns.

The variable-speed centrifugal atomizer operates from 12,000 to 25,000 RPM, providing the flexibility to generate particle sizes from 10 to 180 microns depending on the atomizer speed, feed concentration, and process temperature settings. This wide operating window enables process development scientists to systematically explore the relationship between atomization parameters and final powder characteristics, generating the data necessary for successful technology transfer to production-scale equipment. The atomizer drive features water-cooled precision bearings with integrated temperature monitoring and automatic over-temperature shutdown for reliable continuous operation.

Process data acquisition is managed by the integrated PLC control system with touch screen HMI, providing real-time trending of all critical parameters including inlet and outlet temperatures, atomizer speed, feed rate, and system pressure drops. The data logging capability captures complete process signatures for every experimental run, supporting the rigorous documentation requirements of pharmaceutical development, regulatory submissions, and technology transfer packages. The system also supports recipe storage for up to 100 different product configurations, dramatically reducing setup time when revisiting previously developed formulations.

Pharmaceutical development organizations rely on this pilot spray dryer for producing amorphous solid dispersions, inhalable dry powder formulations, and microencapsulated drug delivery systems during the critical pre-clinical and Phase I/II clinical trial stages. The 316SS construction provides the chemical compatibility necessary for processing hydrochloride and mesylate salt forms of active pharmaceutical ingredients (APIs). The comprehensive data logging supports the quality-by-design approach increasingly required by regulatory agencies, with complete process signatures available for inclusion in investigational new drug and new drug application submissions.

In advanced ceramics and materials science, the pilot system bridges the gap between laboratory-scale powder synthesis and production-scale manufacturing of technical ceramics including alumina, zirconia, silicon nitride, and barium titanate. The 316SS construction withstands the mildly acidic conditions often present in ceramic binder systems, while the precise particle size control enables development of powders with the narrow particle size distributions required for advanced ceramic forming processes including tape casting, injection molding, and additive manufacturing.

Specialty chemical manufacturers utilize this equipment for developing and scaling up production of catalysts, pigments, battery materials, and functional coating precursors. The flexible capacity range allows a single pilot investment to serve multiple roles from initial process feasibility studies through to commercial sample production for customer qualification. Contract development and manufacturing organizations appreciate the rapid changeover capability and comprehensive documentation, which support efficient multi-client pilot plant operations with full traceability between campaigns.

Each pilot spray dryer is shipped in export-standard wooden crating with vacuum-sealed protective wrapping, desiccant moisture protection, and high-density foam cushioning for all precision components. The 316SS surfaces receive passivation treatment prior to packaging to ensure optimal corrosion resistance upon installation. Complete documentation includes equipment datasheets, material certifications (3.1 mill test reports for 316SS), surface finish measurement reports, P&ID diagrams, electrical schematics, and comprehensive installation and operation manuals.

Factory acceptance testing encompasses hydrostatic pressure testing, mechanical run testing of the atomizer at all operating speeds, electrical safety verification per IEC 61010, and full control system functional validation with simulated process sequences. A 12-month comprehensive warranty covers all manufacturing defects, with optional on-site installation supervision, process development support, and preventive maintenance programs available. Our application engineering team provides scale-up correlation assistance to help customers translate pilot-scale results into successful production-scale implementations.
