Abstract:
A device for generating micro spheres from a fluid (13) comprises an injection plate (6) which comprises at least one defined injection channel (1) having on an inlet side an inflow opening for receiving the fluid and on an outlet side an outflow opening for delivering micro spheres (12) formed from the fluid. The device is provided with feed means for carrying the fluid through the injection channel and is in open communication, on a side wall thereof, with at least one secondary channel (10) at least at the position of a break-up point where at least during operation a flow of the fluid in the injection channel breaks up into separate parts. The secondary channel is intended and adapted to comprise an auxiliary fluid at least during operation and at least at the position of a break-up point. For at least a part of the first fluid an inflow resistance of the secondary channel is greater than an inflow resistance of the injection channel. Such a device is employed in a method for injecting a first fluid into a second fluid and a cross-flow of a second fluid is guided over an outlet side of the injection plate.
