Effective droplet drying

摘要

In one aspect, the invention provides a system and method for spray drying a fluid. The system comprises a fluid reservoir (2), a spraying device (3) that comprises at least one outflow opening (4) for projecting droplets of fluid (5) from the reservoir (2) out of the at least one outflow opening (4) and at least one energy source (6) for at least partially drying the droplets. The spraying device (3) is arranged to project the droplets into a determinable droplet trajectory and the at least one energy source (6) is arranged for providing energy focused substantially on the droplet trajectory. It is an object of the invention to provide a system and method for reducing the amount of energy required for spray drying.

1. A system for spray drying a fluid, the system comprising:
a fluid reservoir; a spraying device, the spraying device comprising at least one outflow opening, for projecting droplets of fluid from the reservoir out of the at least one outflow opening; and at least one energy source for at least partially drying the droplets, wherein the at least one energy source is an electromagnetic radiation source; and wherein the spraying device is arranged to project the droplets into a determinable droplet trajectory, and wherein the at least one energy source is positioned with respect to a reflective energy focusing element so as to focus the energy from the at least one energy source in at least one focal point, arranged for providing energy focused substantially on the droplet trajectory.
