A dispensing unit for dispensing hot, dairy-based beverages has a self-contained refrigerated unit located above a venturi-type emulsification foaming head. The dispensing unit has particular applicability to the dispensation of foamy, hot milk for use in beverages such as cappuccino and nonfoamy, hot milk for use in beverages such as coffee latte, hot chocolate, and other hot dairy-based beverages. The refrigeration unit accommodates a "bag in box" cold milk storage container of the type widely used in food service establishments. The dispensing unit employs a pinch valve that avoids direct contact between the milk and the valve components. The refrigerated milk is stored above the level of the foamer head so that the flow of milk results partially from gravitational force on the milk, and is not totally dependent upon venturi suction created in the foamer head.

We claim: 1. 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. 2. A device according to claim 1 wherein said chilled reservoir is comprised of a disposable container including a flexible, collapsible bag of milk and said flexible milk discharge hose extends from said box for draining milk from said bag, and said milk discharge hose extends downwardly from said upper compartment of said housing and through said dairy liquid flow control pinch valve. 3. A device according to claim 2 further comprising a solenoid actuator that operates said pinch valve. 4. A device according to claim 1 further comprising a flow restrictor having a longitudinal orifice therethrough, and said flow restrictor is inserted into upwardly directed, tubular milk inlet pipe.
