Compact Laboratory Centrifugal Spray Dryer with 3-20 kg/h Evaporation Rate, Precision Particle Control, and PLC Touch Screen

The Benchtop Laboratory Centrifugal Spray Dryer is a compact, high-precision drying instrument engineered specifically for research and development environments. Designed for laboratories, universities, and pilot-scale facilities, this equipment transforms small-volume liquid samples into uniform dry powders with exceptional control over particle morphology and size distribution. Its benchtop footprint makes it an ideal addition to any laboratory setting where space is limited but performance demands are high.

At the core of this laboratory spray dryer is a high-speed centrifugal atomizer capable of rotation speeds from 10,000 to 30,000 RPM. This broad rotational range allows researchers to fine-tune the atomization energy applied to the feed material, directly influencing the resulting particle size from as fine as 5 microns to as large as 150 microns. Such precision enables meticulous experimentation with different formulations, concentrations, and processing conditions, making this unit indispensable for product development across pharmaceuticals, advanced ceramics, specialty chemicals, and functional food ingredients.

The integrated PLC touch screen control system provides real-time monitoring and data logging of critical process parameters including inlet temperature, outlet temperature, atomizer speed, feed rate, and airflow velocity. Researchers can save and recall up to 50 different processing recipes, dramatically reducing setup time between experiments and ensuring reproducibility. The system also supports USB data export for comprehensive analysis and documentation, meeting the rigorous record-keeping requirements of regulated research environments.

With an evaporation capacity ranging from 3 to 20 kilograms per hour, this spray dryer bridges the gap between bench-top experimentation and small-scale production. The dual-fluid nozzle option further extends its versatility, allowing for both centrifugal and pneumatic atomization modes within a single platform. The inlet temperature is adjustable from 140°C to 350°C, while the outlet temperature is maintained between 80°C and 120°C. This thermal flexibility is critical when working with heat-sensitive biological materials, enabling gentle drying conditions that preserve bioactivity and structural integrity.

Constructed with 304 stainless steel for all product-contact surfaces, the unit meets stringent cleanliness and corrosion resistance standards. The borosilicate glass drying chamber provides full visual access to the atomization and drying process, an invaluable feature for educational demonstrations and process troubleshooting. The cyclone separator and collection vessel are designed for quick disconnect and easy cleaning, minimizing cross-contamination risks between experimental batches. An optional inert gas loop system is available for processing oxygen-sensitive or solvent-based materials, extending the unit’s applicability to advanced material science research.

This benchtop centrifugal spray dryer excels in research-intensive environments where material quantities are limited and process flexibility is essential. In pharmaceutical R&D, it enables the production of inhalable dry powder formulations, amorphous solid dispersions for solubility enhancement, and microencapsulated drug delivery systems. The precise particle size control and gentle drying conditions are critical for maintaining the stability and bioavailability of active pharmaceutical ingredients during development.

In advanced materials science, researchers utilize this equipment for synthesizing catalyst precursors, battery electrode materials, and ceramic nanopowders. The ability to produce uniform spherical particles with controlled porosity makes it particularly valuable for developing functional coatings, thermal barrier materials, and additive manufacturing feedstocks. The optional inert gas system extends applicability to air-sensitive and pyrophoric materials, opening avenues for cutting-edge nanomaterial research.

Food science laboratories benefit from the spray dryer’s capability to microencapsulate flavors, probiotics, enzymes, and nutraceuticals. The low outlet temperature ensures that heat-labile bioactive compounds retain their functional properties through the drying process. Academic institutions find the transparent chamber particularly valuable for teaching mass transfer, heat transfer, and particle engineering principles in chemical and food engineering curricula.
