Abstract
Abstract An improved mixing, blending and dispensing apparatus for milk shake machines in fast food restaurants which dispense a plurality and a variety of selected flavored milk shakes simultaneously. An unflavored comestible, such as a milk shake mix, or the like, is injected under pressure into a premix chamber together with a selected flavor syrup. As the comestible substance and the flavor syrup flow toward a mixing chamber, they tend to blend together. In the mixing chamber the comestible and the flavor syrup are throughly mixed by an agitator-mixer rotatably mounted within the cylindrical mixing chamber and forced downward through a dispensing nozzle into a serving container. The injection of both of the comestible substance and flavor syrup under pressure into a premixing chamber, the subsequent flow of this combination mixture into the mixing chamber, the action of a rapidly moving flexible shaft mixer, and its forced exit through a dispensing nozzle combine to produce a throughly mixed milk shake of consistent flavor and color, while leaving the mixing chamber relatively clean and free of food products, avoiding carry-over between flavors and permitting rapid service.

Claim 1
Independent Claim
341 words
A multiple head mixing, blending and dispensing apparatus for mixing and dispensing a variety of flavored comestibles such as milk shakes from a single machine having a reservoir of unflavored comestible and reservoirs of flavoring syrups, comprising: a housing mounted on the front panel of a milk shake machine in communication with its reservoir of unflavored comestible and its reservoirs of flavoring syrups; a plurality of mixing, blending and dispensing heads mounted within said housing, each of which is in communication with said reservoir of unflavored comestible and each of which is in communication with at least one reservoir of flavoring syrup; and each of which may be operated simultaneously with the others; selection means to select the desired flavoring syrup to be mixed, blended and dispensed from each head; a premix compartment within said housing communicating with said comestible and flavor reservoirs; a comestible inlet port for admitting said unflavored comestible under pressure into said premix compartment; at least one flavoring inlet port downstream from said comestible inlet port for admitting a flavoring under pressure into said comestible flow entering said premix compartment; a blending compartment within said housing downstream from and communicating with said premix compartment; a plurality of channels interconnecting said premix chamber to said blending compartment; said premix compartment, in combination with said comestible and flavor pressurized flows and said channels, being disposed to produce a turbulent mixing of said flavoring and said comestible; blender means rotably mounted within said blending compartment; blender power means rotating said blender; a dispensing nozzle attached to said housing downstream from and communicating with said blending compartment; and manually operable control means for actuating said blender power means, for controlling the flow of said comestible, and for controlling the flow of said flavoring within said head; a dispensing nozzle attached to said housing downstream from and communicating with said blending compartment; and manually operable control means for controlling the flow of said comestible, and for controlling the flow of said flavoring within said head and for activating said blender power means.

A multiple head mixing, blending and dispensing apparatus for mixing and dispensing a variety of flavored comestibles such as milk shakes from a single machine having a reservoir of unflavored comestible and reservoirs of flavoring syrups, comprising: a housing mounted on the front panel of a milk shake machine in communication with its reservoir of unflavored comestible and its reservoirs of flavoring syrups; a plurality of mixing, blending and dispensing heads mounted within said housing, each of which is in communication with said reservoir of unflavored comestible and each of which is in communication with at least one reservoir of flavoring syrup; and each of which may be operated simultaneously with the others; selection means to select the desired flavoring syrup to be mixed, blended and dispensed from each head; a premix compartment within said housing communicating with said comestible and flavor reservoirs; a comestible inlet port for admitting said unflavored comestible under pressure into said premix compartment; at least one flavoring inlet port downstream from said comestible inlet port for admitting a flavoring under pressure into said comestible flow entering said premix compartment; a blending compartment within said housing downstream from and communicating with said premix compartment; a plurality of channels interconnecting said premix chamber to said blending compartment; said premix compartment, in combination with said comestible and flavor pressurized flows and said channels, being disposed to produce a turbulent mixing of said flavoring and said comestible; blender means rotably mounted within said blending compartment; blender power means rotating said blender; a dispensing nozzle attached to said housing downstream from and communicating with said blending compartment; and manually operable control means for actuating said blender power means, for controlling the flow of said comestible, and for controlling the flow of said flavoring within said head; a dispensing nozzle attached to said housing downstream from and communicating with said blending compartment; and manually operable control means for controlling the flow of said comestible, and for controlling the flow of said flavoring within said head and for activating said blender power means.
Claim 3
Dependent Claim
44 words
The apparatus of claim 1 including a plurality of flavoring inlet ports for admitting a flavoring under pressure into said premix compartment and wherein said manually operable control means is arranged to selectively control the flow of said flavorings through said flavoring inlet ports.
Claim 4
Dependent Claim
17 words
The apparatus of claim 1 wherein said dispensing nozzle is comprised of a plurality of straightening channels.
Claim 5
Dependent Claim
253 words
The multiple mixing, blending and dispensing head of claim 1 wherein each of said heads comprises: a bore within said housing, said housing further having a comestible inlet port communicating with said bore for admitting an unflavored comestible under pressure into said bore, said housing further having at least one flavoring input port of admitting a flavoring under pressure into said bore; a piston slidably mounted in said bore, said piston having an upper, a middle and lower portion, said upper and lower portions fitting snuggly within said bore, said middle portion of a lesser diameter than said upper and lower portions, said middle portion defining a premix compartment within said bore; lever means to slide said piston within said bore to bring said middle portion coincident with said comestible inlet port and said flavoring inlet port; a blending compartment within said housing, said blending compartment positioned downstream from and communicating with said piston middle portion; a plurality of channels interconnecting said premix compartment with said blending compartment; a blender blade rotably mounted within said blending compartment; a power shaft attached to said blender blade extending axially through said piston; blender power means for rotating said power shaft and said blender blade; at least one dispensing nozzle comprised of straightening channels attached to said housing said nozzle positioned downstream from and communicating with said blending compartment; and switch means for activating said blender power means, for controlling the flow of said comestible and for controlling the flow of said flavoring within said head.
