Patent ID: 7021206

Claim:
In a device including a venturi-based emulsification unit for emulsifying dairy-based liquids with other fluids and dispensing an emulsified mixture of said fluids into a beverage container for consumption, the improvement comprising a housing containing a refrigerated upper compartment with a chilled reservoir of milk and having a flexible milk discharge hose having a proximal end located at and connected to said reservoir and an opposite, distal end, and said discharge hose extends from said proximal end to drain milk from said reservoir of milk and is coupled to said emulsification unit therebeneath, an electrically operated dairy liquid flow control pinch valve that acts externally upon said discharge hose and holds said discharge hose in a vertical orientation wherein said pinch valve is located between said upper compartment and said emulsification unit, and said emulsification unit includes an upwardly directed tubular milk inlet pipe located vertically beneath said pinch valve and said distal end of said discharge hose is severed and placed coaxially onto said liquid inlet pipe, whereby activation of said electrically operated dairy liquid flow control pinch valve allows gravitational flow of said milk in a straight, vertical path vertically downwardly out of said reservoir of milk and directly into said emulsification unit.
