Small-Scale Spray Dryers Support Process Scale-Up

ANDRITZ has developed a new generation of small-scale spray dryers designed to support product development, process optimisation, and scale-up. The systems enable controlled testing and validation while replicating industrial drying conditions.

Bridging Laboratory and Industrial Production
Scaling spray drying processes from laboratory trials to full-scale production presents challenges related to process stability, product consistency, and energy efficiency. Variations in drying behaviour can lead to deviations in particle size, moisture content, and powder quality.

The new systems address these challenges by providing a controlled environment for process validation. By enabling testing under conditions that reflect industrial operation, operators can generate reliable scale-up data before committing to full-scale production.

Modular Design for Flexible Operation
The spray dryer range includes six models with evaporation capacities from 5 to 250 kg per hour. This capacity range supports applications from early-stage development to small-scale production and industrial validation.

Systems are available in single-stage and multi-stage configurations, with optional integration of fluid bed technology. The addition of a fluid bed enables further drying and particle conditioning, improving powder properties and overall process efficiency.

The modular, skid-mounted design allows plug-and-play installation, reducing setup time and enabling rapid deployment in different environments.

Supporting Process Optimisation and Product Development
The systems are designed to support iterative product development, where frequent adjustments to formulations and process parameters are required. Operators can conduct controlled experiments to analyse drying performance, optimise process conditions, and troubleshoot production challenges.

This approach reduces development cycles by enabling faster validation of process parameters and product characteristics. It also minimises the need to interrupt large-scale production lines for testing, improving overall operational efficiency.

Compliance with Safety and Hygiene Standards
The spray dryers are designed in accordance with international safety and hygiene standards, including requirements for fire protection and clean processing environments. This is particularly important in industries such as food, dairy, and nutraceuticals, where product safety and quality are critical.

The systems’ design supports hygienic operation and simplifies cleaning processes, ensuring compliance with regulatory requirements across different sectors.

Enabling Efficient Scale-Up in Process Industries
The introduction of modular small-scale spray dryers demonstrates how equipment design can support faster and more reliable scale-up. By combining flexibility, controlled process environments, and industrial relevance, the systems enable manufacturers to optimise formulations and transition to production with reduced risk.
