Abstract
The present invention provides for precision stirrers and mixers which are precision devices for the control of mixing and stirring in liquid and non-liquid systems. As will become obvious, the devices provided for in the present invention may be used for mixing or stirring by adjusting the device configurations and allow precise desired ingredient addition.

A stirrer for precisely metering desired ingredients for dilution comprising
- at least one rotating disk and a central shaft and means for rotating said central shaft;
- wherein the rotating disk is mounted to the central shaft;
- said central shaft passing through the center of the rotating disk;
- and the rotating disk has a top face and a bottom face and at least one channel is cut through the disk;
- wherein said at least one channel cut through the disk can be deemed to pass through the disk at an alpha angle wherein said alpha angle is measured between a ray on the plane of the surface of the disk and a second ray along the channel penetration through the disk and a projection of the channel penetration through the disk projected onto the surface of the disk can be deemed to pass through the disk at a beta angle wherein said beta angle is measured between a ray originating from the center of the disk along the tangent at a particular distance from the center of the disk and a ray along the channel penetration projection upon the surface of the disk;
- wherein the at least one channel penetration is precisely located and dimensioned to allow for precise calculation and measurement of flow through said channel according to the equations Qh=CA*4π2 r2*R*N [cm3/min] wherein Qh represents the pumping rate of the disk, CA represents the reactant concentration, r represents the disk radius, R represents the distance from the disk center, and N represents the disk rotation rate [cm3/min] and

- wherein A represents the opening-area of the channel, fia represents the contribution of the scoop-factor, dh represents the diameter of the channel, and Rh represents the radius of channel;
- and wherein the alpha angle and beta angle of each channel are determined to precisely meter the desired ingredients flow rates through the stirrer;
- wherein the disk may be rotated in either a clockwise or counterclockwise direction while still precisely measuring the flow through each said channel.

A mixer for precisely metering desired ingredients for mixing comprising
- at least two rotating disks and a central shaft and means for rotating said central shaft;
- wherein each of the at least two rotating disks are i-s mounted to the central shaft;
- said central shaft passing through the center of each of the at least two rotating disks;
- and each of the at least two rotating disks has a top face and a bottom face and at least one channel is cut through each of the at least two rotating disks;
- wherein said at least one channel cut through each of the at least two rotating disks can be deemed to pass through the disk at an alpha angle wherein said alpha angle is measured between a ray on the plane of the surface of the disk and a second ray along the channel penetration through the disk and a projection of the channel penetration through the disk projected onto the surface of the disk can be deemed to pass through the disk at a beta angle wherein said beta angle is measured between a ray originating from the center of the disk along the tangent at a particular distance from the center of the disk and a ray along the channel penetration projection upon the surface of the disk;
