Wurster Coating Spray Gun ( Bottom Spray Gun )
A Wurster coating gun (also known as bottom spray gun) is a precision Spray nozzle utilized in fluid bed processors for microencapsulation and uniform particle coating.
Wurster coating, also known as fluid bed microencapsulation, is a process in which discrete particles are encapsulated in a fluidized bed using differential airflow to create cyclic particle movement.
The process can be applied to a wide range of core materials with different particle sizes and shapes.
In the Wurster coating process, heated air is introduced from the bottom of the fluid bed to fluidize the particles and evaporate the solvent from the coating solution, ensuring efficient drying and uniform coating.
The coating gun is located at the bottom plate ( Perforated ) , Spraying coating material upward in the direction of particle flow.
The Wurster coating gun generally produces a fine Full cone spray pattern with spray angles typically ranging from 20° to 30°,
Depending on the coating application requirements.
