Abstract: A dispense tap for a frozen beverage machine has a transition section defining a tapered bore with an inlet for frozen beverage from a freeze barrel of the machine and an outlet for frozen beverage controlled by a valve operable by a handle. The handle is rotatable to allow frozen beverage to flow from the transition section through a dispense cavity in the valve for exiting the tap. The outlet has a cross-section greater than the cross-section of the inlet which prevents ice conglomerating and forming a plug in the bore of the transition section.
