BÜCHI Labortechnik AG Description of function | 4 4 Description of function 4.1 Purpose and design The Ultrasonic Nozzle generates wet droplets with a mean size of 50–200 μm after feed injection into the Mini Spray Dryer B290. The droplet size depends on the feed properties and process conditions such as solvent type, viscosity, surface tension, type of feed, atomization power and feed rate. 4.2 Function 4.2.

BÜCHI Labortechnik AG Description of function | 4 4.2.1.2 Type of liquid The type of liquid being atomized strongly influences the minimum power level. More viscous liquids or liquids with highsolids content generally increase the minimum power requirement. 4.2.1.3 Flow rate The flow rate also plays a role in determining minimum power level. For a given nozzle, the higher the flow rate, the higher will be the power required, since the nozzle works harder as the flow rate increases. 4.2.1.

BÜCHI Labortechnik AG Description of function | 4 ber of drops in the sample. The weight mean diameter is obtained by adding to gether the volume of each drop in a spray sample (volume is proportional to di ameter cubed), taking the cube root of this sum, and finally dividing by the num ber of drops. The Sauter mean diameter is a specialized parameter used pri marily in combustion applications. It measures the effective ratio of drop volume to surface area. 4.4 Broadband Ultrasonic Controller Fig.
4 | Description of function BÜCHI Labortechnik AG The high frequency electrical energy required by the spray nozzle is provided by the Broadband Ultrasonic Controller. This power source offers an array of fea tures that both simplify and enhance the operation of the nozzle systems: • Advanced phaselockedloop control technology to automatically lock onto a nozzle’s specific operating frequency. • Regulated output assures that the power delivered to a nozzle remains con stant.
