Spray drying: Operation, Optimization and Design Aspects - Webinar (Recorded)

  • Webinar

  • 90 Minutes
  • April 2019
  • World Compliance Seminar
  • ID: 4755611
This 90-minute online training focuses on Spray-Drying process and technology, which is present in numerous industries. Even though the training will focus on the fundamentals of Spray-Drying by emphasizing scientific principles that are common to any industry, specific examples will be given for applications in Food, Beverages, Chemicals, Pharmaceuticals, Pulp and Paper, etc. The course will balance the science behind Spray-Drying with real-world challenges that are faced on the day-to-day routine of Operations, Engineers and Science Professionals.
