Emulsification system

1. A method of assembling an emulsification system is provided, the method comprises the steps of:

placing a plurality of screens and a plurality of cutting assemblies upon a shaft and within a housing, wherein the plurality of screens and the plurality of cutting assemblies are disposed upon the shaft such that each screen of the plurality of screens alternates with each cutting assembly of the plurality of cutting assembly, wherein a first cutting assembly is disposed upon a shaft such that it is closest to a distal end of the shaft, wherein the plurality of screens are each fixed with respect to the housing such that the screens do not rotate with rotation of the shaft, and wherein the plurality of cutting assemblies are fixed to the shaft such the cutting assemblies rotate with rotation of the shaft and with respect to the plurality of screens, wherein the plurality of screens and plurality of cutting assemblies are each longitudinally movable along the shaft,

wherein each of the plurality of cutting assemblies include a central hub, a plurality of cutting elements that extend radially outward from the hub and are spaced with a consistent angular spacing from adjacent cutting elements around the a perimeter of the hub, and wherein the screen includes opposite first and second side surfaces and a plurality of holes that extend therethrough,

wherein each of the cutting elements comprise first and second parallel side surfaces and first and second parallel end surfaces, wherein edges are formed where each of the first and second side surfaces meet the first and second end surfaces, wherein each of the edges are substantially perpendicular between the respective side and end surface defining the edge;

placing a collar upon the shaft and in proximity to a hub of the first cutting assembly,

rotating a nut upon a threaded portion at the distal end of the shaft in a first direction until an end surface of the nut contacts a second end surface of the collar,

continuing to thread the nut in the first direction to slide the collar until a first surface of the collar opposite from the second surface contacts the hub of the first cutting assembly, and continuing to thread the nut in the first direction until further rotation is prevented, wherein a side surface of one or more of the cutting elements upon each cutting assembly contacts the respective first or second side surface of the screen that faces the respective cutting assembly,

rotating the nut in a second direction opposite to the first direction a distance to back the nut away from the second surface a distance between about 0.003 and 0.017 inches from the second surface of the collar.

2. The method of claim 1 , wherein the nut comprises a plurality of detents disposed around a perimeter of the nut with consistent spacing between adjacent detents, and wherein the collar includes a pin that is biased to a first position where the pin extends outwardly beyond the second surface of the collar, wherein the step of rotating the nut in the second direction comprises the step of rotating the nut until the pin is in registry with a first detent of the plurality of detents to extend within the first detent such that the nut is prevented from rotating upon the shaft.

3. The method of claim 2 , wherein the step of rotating the nut in the second direction further comprises rotating the nut in the second direction past the first detent and further rotating the nut in the second direction until the pin is in registry with a second detent of the plurality of detent such and allowing the pin to extend within the second detent such that the nut is prevented from rotating upon the shaft.

4. The method of claim 2 , wherein the collar comprises an operator that is manipulable to move the pin away from the first position and to a second position where the pin no longer extends past the second surface of the collar, wherein the operator is manipulated to withdrawn the pin from the first position before the nut is rotated in the second direction and then releasing the operator when the pin is in registry with a desired detent of the plurality of detents.
