ABSTRACT:
There is disclosed herein a fluid flow apparatus including a discharge nozzle arrangement comprising a single continuous, meandering stainless steel strand to create a planar screen operatively connected at its outer periphery to a diffuser chamber. The screen is adapted to retain a volume of fluid thereabove until the fluid is forced under pressure through the openings between adjacent segments of the strand. Portions of the screen are adapted to flex resiliently downwardly, out of the plane of the outer periphery, to provide additional clearances between adjacent segments of the screen, in the event particulates should tend to build-up, to thereby resist clogging by flushing same. The round cross-section of the strand facilitates continual cleanliness, and serves to produce better-behaved flow out of the nozzle, thereby reducing foaming of the product being discharged during the filling operation. As an alternate embodiment, broken line etched screen serve to provide the downward flexing feature when clogging tends to occur.
