The transition plate 106 includes a top surface 506 facing the extension element 104 and a bottom surface 508 (illustrated in FIG. 1A) facing the external port nozzle 114. The bottom surface 508 includes a plurality of inner fluid outlet ports (e.g. fluid flow passages) 194 radially disposed around a primary fluid outlet port (e.g. fluid flow passage) 184. The primary outlet port 184 may be the dispensing orifice of a fluid channel 185 provided substantially at the center of the transition plate 106. The bottom surface 508 further includes a plurality of outer fluid outlet ports (e.g. fluid flow passages) 502 radially disposed around the inner fluid outlet ports 194. The top surface 506 of the transition plate 106 includes a plurality of long channels (e.g. grooves) 510 and a plurality of short channels (e.g. grooves) 512 radially disposed around a primary inlet port 187 of the transition plate 106.

[0057] Each one of the secondary outlet ports 192 of the extension element 104 corresponds to (e.g. is in fluid communication with) one of the channels 510 and 512 provided on the top surface 506 of the transition plate 106. A first portion of the fluid dispensed from the secondary outlet ports 192 of the extension element 104 may be received at the long channels 510 of the transition plate 106, and may be passed to one or more of inner fluid outlet ports 194 of the transition plate 106. For example, a first portion of the one or more beverage additives (e.g. second beverage fluid) dispensed at the secondary outlet ports 190 of the diffuser block 102 may pass through the secondary outlet ports 192 of the extension element 104, and may be received at the long channels 510 of the transition plate 106. The first portion of the one or more beverage additives may flow through each long channel 510 toward an inner outlet port 194 of the transition plate 106 to be provided to the secondary inlet ports 111 of the diffuser assembly 108 (as illustrated in FIG. 1C) to be mixed with the base fluid received at the primary inlet port 155 of the diffuser assembly 108. The post-mix beverage may be dispensed at the outlet ports 196 of the diffuser assembly 108 and the primary outlet port 308 of the external port nozzle 114.

[0058] On the other hand, a second portion of one or more beverage additives (e.g. second beverage fluid) dispensed at the secondary outlet ports 190 of the diffuser block 102 may pass through the secondary outlet ports 192 of the extension element 104, and may be received at the short channels 512 of the transition plate 106. The second portion of the one or more beverage additives may flow through each short channel 512 toward an outer fluid outlet port 502 of the transition plate 106 to be provided to the inlet ports 336 of external port nozzle 114 (as illustrated in FIG. 1C) to be dispensed at the secondary outlets 306 of the external port nozzle 114 before, after or concurrently with the post-mix beverage dispensed at the primary outlet 308 of the external port nozzle 114.

[0059] For example, the non-mixed fluid may be dispensed at the secondary outlet ports 190 of the diffuser block 102, pass through the secondary outlet ports 192 of the extension element 104, and may be received at the short channels 512 of the transition plate 106. Since the non-mixed fluid will not be mixed with the base beverage or other fluids in the diffuser assembly 108, the non-mixed fluid is not provided to the diffuser assembly 108. Rather, the outer fluid outlet ports 502 of the transition plate 106 provide the non-mixed fluid directly to the fluid inlet ports 336 of the external port nozzle 114. The non-mixed fluid by-passes the diffuser assembly 108 and reaches the fluid inlet ports 336 of the external port nozzle 114 directly from the outer fluid outlet ports 502 of the transition plate 106.

[0060] The transition plate 106 allows the beverage dispensing system 100 to dispense a post-mix beverage fluid at the primary fluid outlet port 308 of the external port nozzle 114 and a non-mixed beverage fluid at the one or more of the secondary outlet ports 306 of the external port nozzle 114 without having cross-contamination between the post-mix beverage fluid and the non-mixed beverage fluid. According to various embodiments, the non-mixed beverage fluid may be dispensed before, after or at the same time as (e.g. concurrently with) the post-mix beverage fluid.

[0061] In many embodiments, the external port nozzle disclosed above is configured to enable dispensing both post-mix and premix beverages from one (e.g. a single) nozzle assembly. For example, in some embodiments, the device may include a transition plate configured to couple with a conventional dispensing array, so that a user can improve an existing dispensing system through incorporation of a device in accordance with the present invention. Although in many embodiments, the external port nozzle is a separate component, it is appreciated that the features of the nozzle with isolation porting may be integrated with and/or incorporated into the diffuser assembly in a variety of ways, in accordance with the principles of the present invention.

[0062] The above description is illustrative and is not restrictive. A recitation of “a”, “an” or “the” is intended to mean “one or more” unless specifically indicated to the contrary. Many variations of the disclosure will become apparent to those skilled in the art upon review of the disclosure. One or more features from any embodiment described herein may be combined with one or more features of any other embodiment without departing from the scope of the disclosure. The scope of the disclosure should, therefore, be determined not with reference to the above description, but instead should be determined with reference to the pending claims along with their full scope or equivalents.
