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.
Claims12
A method for controlling temperature of a liquid dispensing head that has a tip through which liquid is dispensed, said method comprising:
- (a) supplying a cool airflow to a passage of said dispensing head through which said liquid passes;
- and
- (b) capturing a volume of said cool airflow in a chamber adjacent said tip to shield said tip from ambient temperature, thereby maintaining said tip at a cool temperature to avoid contamination of said liquid.
A liquid dispensing system comprising:
- a liquid dispensing head comprising a passage therethrough and a liquid delivery tip, through which liquid is dispensed and which is disposed adjacent a chamber;
- and
- means for circulating a cool airflow through said passage into said chamber to shield said tip from ambient temperature, thereby maintaining said tip and said passage at a cool temperature to avoid contamination of said liquid.
