Abstract
Liquid dispensing equipment that includes a dispensing head that maintains a liquid or beverage line and delivery tip at a cool temperature so as to avoid contamination of the beverage. The liquid dispensing equipment also includes a storage refrigerator that cools a container of the beverage. A fan assembly is disposed to develop a cool airflow that flows through the storage refrigerator and a passage of the dispensing head. The liquid line and a delivery tip are disposed in the passage. A baffle arrangement maintains a volume of the cool airflow in a chamber adjacent the delivery tip so as to provide a shield against warmer ambient temperatures.
