Abstract
Abstract A multi-flavor dispensing freezer which will selectively dispense a flavored food product in any one of a plurality of flavors. An unflavored comestible, such as ice cream, frozen custard, or the like, is forced into a dispensing nozzle. As the comestible flows toward the exit of the nozzle it is intermixed with the desired flavor. A combination of agitator-mixer-scraper mounted within the dispenser nozzle and which rotates at a rapid speed, with a scraper cleaning the syrup from the wall of the mixing chamber. The syrup being heavier and with a lower freezing point than the bulk milk mixture, is thrown out of solution by centrifugal force but is then folded back into solution with the body of the mixture as it rapidly passes through the chamber. This action causes complete mixing of the unflavored comestible and desired flavor, such that the product dispensed is uniform in color and flavor and between the centrifugal force of the fast turning agitator and the scraper blades, leaves the surfaces of the equipment clean and relatively free of food product, avoiding dripping and carry-over between flavors without other cleaning, in rapidly serving product.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
243 words
A dispensing device for an unflavored comestible incorporating a distributor mechanism for introduction of a desired flavor into the comestible being dispensed and a blender device for uniformly blending the flavor into the unflavored comestible, comprising: a dispensing nozzle having a first port therein for introduction of an unFlavored comestible therethrough and one or more additional ports downstream from the first port for introduction of a desired flavor into the unflavored comestible, a moveable, internal, axial sleeve mounted in the dispensing nozzle for controlling flow of the unflavored comestible into the nozzle, means for continuously feeding the unflavored comestible through the first port, means for introducing flavoring through the additional port, a rotatable shaft extending into the dispensing nozzle, means for rotating the shaft, and blender means extending longitudinally within the dispensing nozzle and mounted to the end of the shaft downstream from the point of introduction of the flavoring into the unflavored comestible, the blending means including (1) an upstream portion having outwardly extending blades with surfaces at an angle to the axis of the shaft for imparting a swirling motion and shearing action to the introduced comestible and flavoring mixture, and (2) a downstream portion extending outwardly from the shaft the width of the interior of the dispensing nozzle providing shearing action to the comestible-flavoring mixture and removing the more dense portion of the mixture from the walls of the nozzle and folding it back into the remainder of the mixture.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
23 words
The device of claim 1 wherein the downstream portion further includes diametrically projecting rods substantially normal to the shaft providing further shearing action.
Claim 4
Dependent Claim
52 words
The device of claim 1 wherein the downstream portion includes shearing vanes extending the width of the interior of the dispensing nozzle having openings therein permitting passage of the comestible-flavoring mixture therethrough and integral scraping means on the outer terminating edges thereof in contact with the inner surface of the dispensing nozzle.
Claim 5
Dependent Claim
165 words
A combination blender and distributor mechanism for use with a comestible dispenser, comprising: a dispensing nozzle including an outer, reltively fixed first sleeve having a part radially bored therethrough and a larger port axially spaced therefrom, axially moveable second sleeve plunger means sealingly mounted within the first sleeve means and adapted to selectively open and close the larger port, rotatable shaft means coaxially mounted within the first and second sleeve means having a combination agitator and mixer mounted to its lower end, said agitator and mixer comprising (1) a first portion having paddles extending outwardly from the shaft at an angle to the shaft and (z) a second portion downstream from the first portion having scrapers generally parallel to the shaft and adapted to contact the inner surface of the first sleeve, means for rotating the shaft, and means for axially moving the plunger means to expose the larger port to the interior of the first sleeve for introduction of comestible into the dispensing nozzle.
