A mixing and flushing device for use on a proportioning pump of a juice tower dispenser. The device includes a housing having a water inlet connected to the pump water outlet, a concentrate inlet connected to the pump concentrate outlet, a flushing water inlet, a mixing chamber, and a single outlet from the mixing chamber. A poppet valve at the concentrate inlet to the chamber feeds the concentrate in a thin annular stream where it is hit by the water. The flushing water hits the poppet valve and automatically forces it closed during cleaning.

A mixing and flushing device for use on a proportioning pump of a juice dispenser, comprising: (a) a housing having a water inlet, a concentrate inlet, a flushing water inlet, and an outlet; (b) said housing including a mixing chamber therein having an upper water inlet opening, a lower concentrate opening having a circular valve seat where said concentrate opening meets said chamber, and a side outlet opening; (c) a poppet valve in said concentrate opening and having a circular peripheral edge in contact with said valve seat when said poppet valve is in a closed sealing position and having a concave upper surface for receiving water from said water inlet opening and for causing said water to spread out toward said edge; (d) said poppet valve being movable upwardly to an open position when concentrate is pumped into said chamber, providing a narrow annular concentrate opening into said chamber where the water spreading out from the upper surface of the poppet valve contacts a thin layer of concentrate and mixes vigorously with it, and the mixture then leaves the chamber through said side outlet opening; (e) a first water passageway extending from said water inlet to said water inlet opening; (f) a flushing water passageway extending from said flushing water inlet into said first water passageway at a point intermediate its length; and (g) a one-way valve in said flushing water passageway allowing flushing water to go in the direction from said flushing water inlet to said first water passageway.
