Atomizer mixing chamber for a seed treater

An atomizer for a seed treater, the atomizer comprising:

• an atomizer mixing chamber comprising:
• a body;
• a first inlet in the body for receiving a first treatment fluid;
• a second inlet in the body for receiving a second treatment fluid;
• a first stage cup for receiving and combining the first and second treatment fluids to provide a combined fluid, the first stage cup comprising a first set of holes through which the combined fluid flows;
• and a second stage cup below the first stage cup for receiving the combined fluid from the first stage cup, wherein the second stage cup further mixes the combined fluid to provide a mixed fluid and wherein the second stage cup comprises a second set of holes through which the mixed fluid flows;
• a disk for receiving the mixed fluid from the atomizer mixing chamber;
• a motor for rotating the disk;
• and a drive shaft connecting the motor to the disk through a bore centrally disposed within the atomizer mixing chamber.

An atomizer for a seed treater, the atomizer comprising:

• an atomizer mixing chamber comprising:
• a body;
• a first inlet in the body through which a first treatment fluid enters the body;
• a second inlet in the body through which a second treatment fluid enters the body;
• a first stage cup fluidly connected to the first and second inlets to separately receive the first and second treatment fluids and to mix the first and second treatment fluids to provide an initially mixed fluid, the first stage cup comprising a first set of holes through which the initially mixed fluid flows;
• and a second stage cup below the first stage cup for receiving the initially mixed fluid from the first stage cup, wherein the second stage cup further mixes the initially mixed fluid to provide a further mixed fluid and wherein the second stage cup comprises a second set of holes through which the further mixed fluid flows;
• a disk for receiving the further mixed fluid from the atomizer mixing chamber;
• a motor for rotating the disk;
• and a drive shaft connecting the motor to the disk.
