Beam cutter process

The jet cutting process ( jet cutter ), developed by the company geniaLab in Braunschweig, generated liquid particles characterized in that an emergent from a full jet of pressurized liquid jet by means of a rotating jet cutter (symmetrically arranged cutting wires) in uniformly cylindrical segments is cut. In the course of a certain fall distance, the individual liquid segments contract into spherical drops of uniform size due to the surface tension . The size of the droplets (0.2–4 mm) can be adjusted via the rotational speed of the cutting tool, the diameter of the liquid jet and the volume flow through the nozzle (depending on the pressure and temperature of the liquid). The nozzle sits in the jet head .

The advantages of this process are the narrow distribution range of the particles produced, the possibility of using highly viscous fluids and the high mass throughput, especially at high viscosities.
