Abstract

The instant invention is a device for producing dispersions. The device for producing dispersions includes a first stator, a second stator, a shell encasing the first stator and the second stator, a rotor being disposed therebetween the first stator and the second stator thereby forming a first chamber and a second chamber, at least one first inlet port into the first chamber, and at least one outlet port out of the second chamber. The device may optionally include at least one additional second inlet port into the second chamber.

Claims (10)

1. A device for producing dispersions comprising:

a first stator;

a second stator;

a shell encasing said first stator and said second stator;

a rotor, wherein said rotor is disposed therebetween said first stator and said second stator thereby forming a first chamber and a second chamber, wherein said first chamber is a high shear chamber, and said second chamber is a low shear chamber;

at least one first inlet port into said first chamber; and

at least one outlet port out of said second chamber

wherein said rotor has a first surface and a second surface, and said second surface has a less number of ring-shaped rotor teeth than the said first surface.

2. The device according to claim 1 , wherein said device further comprises at least one second inlet port into said second chamber.
