Abstract:
1. A coffee producing device for producing a heated liquid beverage composition from a liquid concentrate, comprising: a housing adapted to dispense a liquid composition comprising a liquid coffee concentrate and water, an actuatable volumetric mix valve assembly located in the housing and having an actuator capable of moving a valve from a first position to at least a second position, wherein in the first position the valve assembly operatively prevents flow of the liquid composition through an outlet of the valve assembly, the valve assembly having a concentrate inlet and a concentrate reservoir having a set volume and being in fluid communication with the concentrate inlet in the first position and adapted to operatively receive liquid coffee concentrate from a concentrate source, wherein in the second position the valve isolates the concentrate inlet from the concentrate reservoir, the valve assembly further comprising a water inlet adapted to receive water from a hot water receptacle through a hot water conduit connected to the inlet, wherein a seal member of the valve prevents flow of water into the concentrate reservoir in the first position, wherein in the second position the valve allows fluid communication between the water inlet, the concentrate reservoir, and the outlet of the valve assembly, at least a portion of the outlet arranged below the water inlet and the concentrate reservoir whereby the water and liquid coffee concentrate from the concentrate reservoir are adapted to flow via gravity out through the outlet in the second position; a water receptacle adapted for receiving water from a water source; a water heater operatively connected to the water receptacle by a conduit; a second conduit operatively connected between the water heater and the hot water receptacle for providing water heated by the water heater to the hot water receptacle; a concentrate receptacle adapted to be connected to the concentrate source comprising the liquid coffee concentrate; and a concentrate conduit operatively connected between the concentrate receptacle and the concentrate inlet of the valve assembly.
