ABSTRACT:
An atomizing nozzle for use in a fluidized coating bed includes an elongated hollow tube defining a chamber therein, the tube including an atomizing end in fluid communication with the chamber and a supply end; an air supply port at the supply end in fluid communication with the chamber; a coating liquid supply port at the supply end, the coating liquid supply port being separated from the air supply port; and a flow control tube extending within the hollow tube between the liquid supply port and the atomizing end, for supplying the coating liquid to be atomized to the atomizing end, the flow control tube having an reduced diameter inner bore providing a controlled flow constriction to the liquid travelling from the liquid supply port to the atomizing end so as to supply the coating liquid from the coating liquid supply port to the atomizing end with a controlled flow constriction, such that there is no need to provide a metering pump or flow meter for each atomizing nozzle of the fluidized coating bed and control of the flow through each atomizing nozzle is readily accomplished by varying the internal bore size of the flow control tubes.
