A batch mixer for mixing a container of concentrate and diluent, the batch mixer comprises a mixing tank; and a drawer assembly for delivering the concentrate to said mixing tank. The drawer includes a multiple position receiving station for permitting the concentrate to be arranged in a plurality of configurations.

Batch mixer

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.

Batch mixer and reservoir lid for a mixing tank

A method and apparatus for mixing a containerized concentrate with diluent from a supply system. In the method, a container of concentrate is placed within a container station. The container is opened. A flowable portion of the concentrate from the container is drained into a mixing volume. A first portion of diluent is introduced into the mixing volume. A residual portion of the concentrate is washed from the container with a second portion of the diluent to produce a volume of wash diluent. The wash diluent is added to the mixing volume. The first and second portions of diluent have a total volume proportional to the total volume of concentrate. The draining is at least substantially completed prior to the washing. The apparatus has a mixing tank and a container that retains the container and delivers the concentrate, through a concentrate outlet, to a mixing tank. An opener is disposed to open the container within the container station. A diluent source receives diluent from the diluent supply system and delivering an aloquot of diluent to the mixing tank. The diluent source is directly coupled to the supply system. The diluent source is separated from the mixing tank by an air gap. A washer receives diluent from the diluent source. The washer delivers diluent to the container station through the concentrate outlet to rinse the container. A controller actuates the washer at least substantially after the delivering of the concentrate to the mixing tank.
