Batch mixer and reservoir lid for a mixing tank

Abstract

A batch mixer and a reservoir lid. The batch mixer has a station for concentrate containers, a diluent source, a reservoir, a mixing tank, and a pump. The station has a container receiver and a concentrate outlet communicating with the receiver. The station delivers a predetermined volume of concentrate through the concentrate outlet. The diluent source has a diluent source outlet. The diluent source is actuable to supply an aloquot of diluent, having a predetermined proportionality to the concentrate volume, through the diluent source outlet at a predetermined rate of flow. The reservoir is disposed to receive the aloquot of diluent from the diluent source outlet. The reservoir has a volume less than the volume of the aloquot. The reservoir has an overflow reservoir outlet disposed to drain diluent in excess of the volume of the reservoir. The mixing tank is disposed to receive the diluent from the overflow reservoir outlet and to receive the concentrate from the concentrate outlet. The pump has an intake disposed in the reservoir and an exhaust directed into the container receiver. The reservoir lid can provide the reservoir for the batch mixer. The reservoir lid includes a shell having a central through-passage and a downwardly directed peripheral margin for engagement of a mixing tank. A reservoir is disposed in the shell between the peripheral margin and the through-passage. The reservoir has an upwardly directed inlet, a downwardly directed weep hole, and an overflow reservoir outlet.
