3.11 Function
The PM powder mixer is a system in which powder or liquid ingredients (e.g., sugar, milk and
cocoa powder, thickeners, oil, flavorings, etc.) are introduced into or dispersed in a base me-
dium solution.
The self-priming centrifugal pump draws in the base liquid supplied in a tank and conveys it
through a short pipe to the shear pump. If the self-priming centrifugal pump is throttled at
the suction side via the throttle valve, a vacuum (of up to approx. 0.5 bar) is built up between
the pump and the valve. This is where the funnel with the inlet for the additive medium is lo-
cated.
The vacuum causes, for example, powder or liquid to be drawn directly into the liquid flow.
First this still-inhomogeneous premix reaches the self-priming centrifugal pump, where it is
premixed. The premix is then pumped by this pump to the shear pump, where the remain-
ing clumps are completely broken up due to the high turbulence at circumferential speeds
of up to 30 m/s.
