Abstract: A post-mix beverage valve provides for automatic, accurate beverage ratioing. A valve body can be assembled, and includes a water flow hard body, syrup body and common nozzle body. The water and syrup flow bodies define flow channels and include one end for connection to water and syrup respectively, and opposite ends for fluid connection to the nozzle body. The water flow channel includes a turbine flow sensor connected to a micro-controller determining the water flow rate. The syrup flow channel includes a flow sensor, two MEMS pressure sensors, monitoring the syrup. The sensors are connected to the micro-controller and positioned about an orifice and senses sense a differential pressure indicative of syrup flow rate solenoid regulates flow of syrup through the syrup body. A stepper motor on the water body controls a rod in the flow channel in conjunction with a v-groove.

Abstract: A thermoelectric module (1) has a plurality of thermoelectric devices (2) integral with heat conducting surfaces (5, 5′) of fluid chambers (3, 3′). The thermoelectric devices (2) are operable to transfer heat to or from fluids in the chambers (3, 3′). A product, eg a beverage, flowing through one of the chambers (3, 3′) can be heated or cooled to achieve a desired product temperature by selective operation of the thermoelectric devices (2). The module (1) provides an integrated unit that avoids inefficient boundaries between the heat conducting surfaces (5, 5′) and the thermoelectric devices (2).

Abstract: The present invention comprises a valve providing for the dispensing of two liquids at a desired ratio. The valve includes first and second liquid flow body assemblies releasably securable to a nozzle body assembly. Each liquid flow body assembly is securable to a source of liquid and includes flow sensing means and flow regulating means. A control receives inputs from the flow sensing means and regulates the operation of the flow regulating means to provide for the dispensing of the two liquids from the nozzle body assembly at a predetermined ratio.

Abstract: The present invention is a valve that provides for automatic and accurate fluid dispensing of two fluids at a predetermined ratio. The valve is designed to be easily assembled and disassembled by hand without the need for hand tools, and includes a diluent flow body and a concentrate flow body releasably securable to a common nozzle body portion. The diluent and concentrate flow bodies each define a flow channel and each include a first end for connection to sources of diluent and concentrate respectively, and an opposite end for fluid connection with the nozzle body. The diluent body flow channel includes a flow sensor connected to a micro-controller for sensing the flow rate of the diluent. The concentrate body flow channel includes a further flow sensor for sensing the flow rate of the concentrate. Stepper motors are secured to both the diluent and concentrate bodies and each operates a linear rod extending there through and through a flow regulator.

Abstract: Cooler for a beverage, e.g. beer, which enables dispense at low temperature with good appearance of the dispensed beverage, comprises an inlet and an outlet, at least one heat exchanger (10, 30, 32) between the inlet and the outlet through which the beverage can be passed to cool it and at least one Peltier plate assembly (12, 14, 42) connected to a voltage supply whereby a cold side and a hot side may be generated at the assembly, characterised in that the assembly (12, 14) is positioned whereby the beverage can also be cooled by passage past the cold side of the assembly (12, 14) on its passage to the outlet or whereby the coolant after passage through the heat exchanger (32) is cooled by passage past the cold side of the assembly (42) before being recirculated to the heat exchanger (32).

Abstract: The present invention is dispensing valve that provides for automatic and accurate fluid ratioing of two fluids. A valve body is designed to be easily assembled and disassembled by hand without the need for hand tools, and includes a first liquid flow body and a second liquid flow body releasably securable to a common nozzle body portion. The first and second liquid flow bodies each include flow sensors and the first liquid flow rate is adjusted to the sensed second liquid flow rate. The flow rate of the first liquid is regulated by a linear actuator operating a shaft through an orifice located in a flow channel of the first liquid flow body. The position of an end of the shaft relative to the orifice regulates the cross-sectional size of the flow channel through the orifice and therefor regulates the flow rate of the first liquid as a function of that cross-sectional size. The flow of the second liquid is regulated by an on/off device.
