Automatic spray drying process control and on-line QC place high demands on the uptime performance of a particle size analyzer, and all Malvern systems are designed from the outset for process use. Key to their success is the ability to be installed almost anywhere, thanks to strong interfacing capabilities, both to the process and to the control system.

  • Highly robust high speed instruments
  • Hygienic fittings to ensure ease of cleaning between production batches of entire sample path
  • Range of options for use in a diverse range of industries from metal powders to pharmaceutical / GAMP4 environments

The particle size and dust loading analyzers are used to both optimize and continually monitor the production of solid and liquid particulates produced by a range of spray drying and atomizer processes. Malvern works with a range of Partenaires who supply plant equipment and recommend the use of Malvern analyzers in their processes.
