Spray Nozzles for Wurster Coater

Several pages will not be sufficient to describe spray nozzles. However important aspects of Wurster Spray Nozzles will be described here.

The nozzle is fitted at the bottom of the wurster and it projects into the perforated bottom plate.
It must give a fine enough spray. The mist must not be too fine, where it spray-dries before touching the particles to be coated. It must not give too big droplets, that will act to stick two or more particles together.
Air-less one media nozzle must be avoided.
External mixing of atomizing air and spray emulsion is a desired spray nozzle.
It must have an auto-shut-off needle to prevent clogging of the nozzle.
Atomizing air is generally used around one bar pressure.

Several OEM makers of Wurster Coaters, compromise on this aspect either due to prohibitive cost of the nozzle and/or due to lack of knowledge. The nozzle must be easily detachable.
