To understand how the homogenizer works and what it does, it is first necessary to
trace the path of the liquid mixture through the homogenizing valve. Figure 1 shows a plug-type homogenizing valve and standard valve seat. The unhomogenized product enters the valve seat from the pump cylinder at a relatively low velocity but at a high pressure. For example, the velocity may be about 10 to 20 feet per second (3.05 to 6.10 m per second). The pressure for this example will be at 3000 psi (207 bar). This pressure is generated by the positive-displacement pump and by the restriction to flow caused by the valve being forced against the seat by an actuating force. The positive-displacement pump provides a relatively constant rate of flow and, therefore, will generate the required pressures as the flow area between the valve and seat is increased or decreased.
