ABSTRACT:
Improved frozen beverage dispensing apparatus includes a latch member for inhibiting operation of the dispensing apparatus when the apparatus is in a defrost cycle. The apparatus includes a container for storing a beverage under pressure in at least a partially frozen state, a normally closed dispensing valve mounted with the container and a manually operable lever for operating the dispensing valve. The dispensing valve has a longitudinal bore communicating with the interior of the container. A defrost relay operates a solenoid at the onset of the defrost cycle to move the latch member into engagement with the lever. When the defrost cycle has been completed, the solenoid disengages the latching member from the lever so that the lever can be operated to open the dispensing valve. A faucet member extends downwardly from the dispensing valve. The faucet member includes a diffusion member for diffusing the frozen beverage passing through the faucet member generally outwardly from a central axis of the faucet member and downwardly. In one embodiment, the diffusion member is a diffusion valve which is biased toward a closed position to prevent passage of the frozen beverage through the faucet member when the dispensing valve is closed.
