Abstract

See full text

The present invention provides, inter alia, for a liquid feeding device for the generation of droplets, in particular for the use in a process line for the production of freeze-dried particles, with a droplet ejection section for ejecting liquid droplets in an ejection direction, the droplet ejection section comprising at least one inlet port for receiving a liquid to be ejected, a liquid chamber for retaining the liquid, and a nozzle for ejecting the liquid from the liquid chamber to form droplets, wherein the liquid chamber is restricted by a membrane on one side thereof, the membrane being vibratable by an excitation unit, wherein the longitudinal axis of the liquid chamber is tilted relative to the longitudinal axis of the nozzle, and/or the liquid feeding device further comprises a deflection section for separating the droplets from each other by means of at least one gas jet, wherein the deflection section gas jet intersects perpendicular with an ejection path of the liquid ejected from the liquid chamber.
