Laboratory Spray Dryer

The solution is injected through a spray nozzle that generates a mist of very small droplets. A stream of very hot air evaporates the solvent forming the droplets and carries the solid into a cyclone. The cyclone separates the solid particles formed from the drying air, which escapes outside the unit. Learn about Laboratory Spray Dryer for educational labs for optimal educational outcomes..

Technical Description: A product solution in a solvent (water) is dehydrated to obtain the product in powdery solid form. The solid is recovered at the base of the cyclone in a suitable reservoir.
