Abstract
Abstract Apparatus for mixing and improving the quality of sauces including a mixing vessel supported on a housing, said housing having a funnel shaped inlet through which the ingredients pass. An annular rotor is rotatable with respect to a stator member, the sauce ingredients being acted on by the same to produce a smooth, improved product. A passageway provides repeat circulation of the mixture through the apparatus and a tap is provided to withdraw the completed sauce.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
126 words
Apparatus for making and mixing sauces comprising a housing, an open-bottom mixing vessel having its open bottom seated on said housing, a stator assembly fixedly mounted in the lower part of said housing, a rotor assembly adapted for rotation within said housing and located centrally therein, and a funnel-shaped opening in the upper part of said housing and in axial alignment with said rotor assembly, said rotor assembly comprising a plurality of circumferentially spaced projections extending downwardly toward the lower part of said housing, the central portion of the rotor assembly being formed as an upstanding truncated cone extending into the funnel-shaped opening, said rotor projections extending from an annular disk member, and a conical wall connecting the base of the truncated cone to said disk.
Claim 2
Dependent Claim
126 words
Apparatus for making and mixing sauces comprising a housing, an open-bottom mixing vessel having its open bottom seated on said housing, a stator assembly fixedly mounted in the lower part of said housing, a rotor assembly adapted for rotation within said housing and located centrally therein, and a funnel-shaped opening in the upper part of said housing and in axial alignment with said rotor assembly, said rotor assembly comprising a plurality of circumferentially spaced projections extending downwardly toward the lower part of said housing, the central portion of the rotor assembly being formed as an upstanding truncated cone extending into the funnel-shaped opening, said rotor projections extending from an annular disk member, and a conical wall connecting the base of the truncated cone to said disk.
Claim 3
Dependent Claim
27 words
Apparatus as defined in claim 1 wherein said conical wall is a continuation of the surface of said funnel-shaped opening in the upper part of said housing.
Claim 4
Dependent Claim
31 words
Apparatus as defined in claim 2, wherein said conical wall is provided with a plurality of openings whereby sauce ingredients placed in said mixing vessel can pass into the rotor-stator area.
Claim 5
Dependent Claim
26 words
Apparatus as defined in claim 3, wherein said openings are circular and are regularly spaced from each other about the entire surface of the conical wall.
Claim 6
Dependent Claim
26 words
Apparatus as defined in claim 1 wherein the stator assembly comprises a plurality of circumferentially spaced projections extending upwardly from the lower part of said housing.
Claim 7
Dependent Claim
106 words
Apparatus for making and mixing sauces comprising a housing, an open-bottom mixing vessel having its open bottom seated on said housing, a stator assembly fixedly mounted in the lower part of said housing, a rotor assembly adapted for rotation within said housing and located centrally therein, and a funnel-shaped opening in the upper part of said housing and in axial alignment with said rotor assembly, the upper part of said housing being provided with a collection space radially spaced from said rotor, and a channel interconnecting said space with said funnel-shaped opening in said housing to establish a loop circulation for the sauce to be produced.
Claim 8
Dependent Claim
106 words
Apparatus for making and mixing sauces comprising a housing, an open-bottom mixing vessel having its open bottom seated on said housing, a stator assembly fixedly mounted in the lower part of said housing, a rotor assembly adapted for rotation within said housing and located centrally therein, and a funnel-shaped opening in the upper part of said housing and in axial alignment with said rotor assembly, the upper part of said housing being provided with a collection space radially spaced from said rotor, and a channel interconnecting said space with said funnel-shaped opening in said housing to establish a loop circulation for the sauce to be produced.
Claim 9
Dependent Claim
17 words
Apparatus as defined in claim 6 and further including a sauce outlet connected to said collection space.
Claim 10
Dependent Claim
79 words
Apparatus for making and mixing sauces comprising a housing having a mixing vessel assembly directly associated therewith, a combined fixed stator assembly and cooperating rotatable rotor assembly within said housing and directly communicating with said mixing vessel assembly, a collection space within said housing in spaced communication with said stator and rotor assemblies, and channel means interconnecting said collection space and said mixing vessel assembly in said housing to establish a loop circulation for the sauce to be produced.
Claim 11
Dependent Claim
79 words
Apparatus for making and mixing sauces comprising a housing having a mixing vessel assembly directly associated therewith, a combined fixed stator assembly and cooperating rotatable rotor assembly within said housing and directly communicating with said mixing vessel assembly, a collection space within said housing in spaced communication with said stator and rotor assemblies, and channel means interconnecting said collection space and said mixing vessel assembly in said housing to establish a loop circulation for the sauce to be produced.
Claim 12
Dependent Claim
15 words
Apparatus as defined in claim 8 including a sauce outlet communicated with said collection space.
Claim 13
Dependent Claim
47 words
Apparatus as defined in claim 8 wherein said rotor assembly includes a central portion formed as an upstanding truncated cone extending into said mixing vessel assembly, said rotor assembly further including a conical wall surrounding said truncated cone central portion and projecting outwardly from one end thereof.
Claim 14
Dependent Claim
33 words
Apparatus as defined in claim 10 wherein the conical wall of said rotor assembly terminates in an annular disc remote from said truncated cone, said rotor assembly projections depending from said annular disc.
Claim 15
Dependent Claim
19 words
Apparatus as defined in claim 11 including openings through said conical wall for the passage of sauce ingredients therethrough.
Claim 16
Dependent Claim
35 words
Apparatus as defined in claim 8 wherein the stator assembly comprises a plurality of annularly spaced projections extending toward the rotor assembly, said projections being four-sided and having plain outer surfaces and curved lateral faces.
Claim 17

Dependent Claim
17 words
Apparatus as defined in claim 14 wherein the remaining faces of each projection are of concave configuration.
Claim 19
Dependent Claim
18 words
Apparatus as defined in claims 13 or 15 wherein the edges of each projection form sharp cutting portions.
Claim 20
Dependent Claim
37 words
Apparatus as defined in claim 13 wherein said rotor assembly comprises a plurality of annularly spaced projections extending toward said stator assembly, said rotor assembly projections being four-sided and having plain outer surfaces and curved lateral faces.
Claim 21
Dependent Claim
