The Greerco® Homogenizer is for use in mixing, emulsifying and dispersing ingredients of varying viscosities. The product is designed for applications in which standard agitation fails to provide the desired process result or production time. The system's rotor-stator design uses an axial-in/axial-out flow pattern that allows for reversible operation. When operated in the forward direction, the unit creates an up-pumping umbrella flow pattern. In the reverse direction, a vortex is created that can be used to incorporate solids directly into the mixing head for immediate dispersion.
