A flow limiter system is provided for extracting compounds from raw materials with an extraction column. The flow limiter system may include a flow governor assembly which contains and buffers a flow of pressurized solvent entering the base of the extraction column to prevent the flow of pressurized solvent from drilling into the raw materials packed within the extraction column. The flow governor assembly may further include a first disc with a first set of perforations to direct the surge of solvent through the first disc to transform the turbulent surge of solvent into a column of non-turbulent solvent with a flat surface layer that rises up the extraction column evenly and collectively. Additionally, the flow limiter system may also include a limiter disc including a second set of perforations to allow the extracted effluent to flow through the set of perforations and exit the extraction column.

A spray head assembly for use with a beverage brewer includes a spray head and an adapter. The spray head includes a back plate having a turn mechanism. The adapter includes a body having an outer portion and a threaded inner portion. The body has an opening through the threaded inner portion that is attachable to a valve of the beverage maker. The outer portion of the body includes ears attachable to the backer plate of the spray head through the turn mechanism.

A coffee maker provides a controlled release of heated water into brewing material. In one embodiment the coffee maker includes a spiraling nozzle releasing heated water over brewing material held in the coffee maker. The nozzle provides a single release point at each instant providing improved exposure of the brewing material to the heated water. In another embodiment the coffee maker includes a rotating sprinkler arm releasing heated water into the brewing material. In either embodiment motion may be provided by the flow of heated water, or by an electric motor.

A diffuser assembly for diffusing fluid in a brewed beverage system is provided. The diffuser assembly includes a diffuser housing having an inlet port configured to receive fluid from a fluid supply, a channel in fluid communication with the inlet port, and a cavity in fluid communication with the channel. The diffuser housing further includes multiple elongate openings formed in an inner surface of the diffuser housing for allowing fluid within the cavity to flow there through. The diffuser housing also includes multiple ridges projecting from the inner surface of the diffuser housing and positioned to distribute the fluid evenly across the inner surface prior to outputting the fluid via the plurality of elongate openings. The diffuser assembly can further include a cover removably coupled to the diffuser housing. Related systems and methods are also provided.

A spray head assembly for use with a beverage brewer includes a spray head and an adapter. The spray head includes a front portion including a plurality of holes for dispensing water therethrough and a backer plate having a turn mechanism. The adapter includes a body having an outer portion and a threaded inner portion. The body has an opening through the threaded inner portion that is attachable to an outlet tube of the beverage brewer. The outer portion of the body includes tabs that are engageable with the turn mechanism of the backer plate by inserting the tabs into the turn mechanism and rotating the backer plate to engage the tabs.

The present invention relates to a beverage machine that comprises: a brewing chamber (20); and a dispensing spout (18) for dispensing liquid into the brewing chamber (20); wherein the dispensing spout (18) comprises: i) a liquid inlet (32); ii) a main body (34) having a central axis (52) and at least a first liquid outlet (42) and a second liquid outlet (44), wherein the second liquid outlet (44) has a larger distance from the central axis (52) than the first liquid outlet (42); iii) a liquid distributor (40) for fluidly connecting the liquid inlet (32) selectively to the first liquid outlet (42) or to the second liquid outlet (44), and iv) an actuator (90) for changing a position of the liquid distributor (40) relative to the main body (34) between at least a first and a second position, wherein in the first position the liquid inlet (32) is fluidly connected to the first liquid outlet (42), and wherein in the second position the liquid inlet (32) is fluidly connected to the second liquid outlet (44).

A beverage-making machine includes: a housing; a serving station that includes a showerhead, a brew basket, a dispensing outlet, and a receptacle platform; a water reservoir; and a heating unit fluidly connected with the water reservoir and with the showerhead. The showerhead includes a water distribution chamber in fluid connection with the heating unit. The showerhead includes a plurality of channels in a lower basin thereof, the channels extending radially outwardly. Each of the plurality of channels includes a plurality of holes, wherein at least one radially outward hole has a greater open area than a radially inward hole.

A group head vortex shower is used in a coffee machine and includes a bottom wall, a surrounding wall and a reflection wall. The surrounding wall extends from the bottom wall, surrounds a central axis, cooperates with the bottom wall to define a water inlet space, and has a plurality of outer outlets that are in fluid communication with the water inlet space. The reflection wall is sleeved around the surrounding wall, and has at least one curved inner surface that surrounds the central axis. Each of the outer outlets outputs a water jet from the water inlet space in a water outlet direction towards the at least one curved inner surface of the reflection wall. An imaginary extension line of each of the outer outlets and the central axis are skew lines.
