Patent Application
20070065552
The present invention relates generally to ice cream products and their methods of preparation, and more particularly to a novelty frozen products product.
Sales of ice cream and frozen yogurt products have risen dramatically in recent years, and applicants herein have captured a portion of this product market through the development of a unique novelty ice cream, frozen yogurt and ice product in the form of beads. This product, marketed under the trademarks “Dippin' Dots®” and “Ice Cream of the Future®”, has become very popular in specialty stores, at fairs and theme parks, and through vending machines.
Applicants have proprietary rights in the method of preparing and storing the product pursuant to U.S. Pat. No. 5,126,156, issued Jun. 30, 1992, herein incorporated by reference, as well as rights associated with improvements pursuant to U.S. Pat. No. 5,664,422, issued Sep. 9, 1997, and U.S. Pat. No. 6,000,229, issued Dec. 14, 1999, herein incorporated by reference. As is generally described therein, the patented method involves flavored liquid dairy and other alimentary compositions to a feed tray and then dripping the composition into a freezing chamber. The feed tray comprises a plurality of orifices through which liquid composition passes to fall into the freezing chamber, either in the form of droplets or liquid streams, which streams break into droplets before freezing. Each orifice may also have a corresponding feed dropper, which is downwardly disposed in relation to the tray such that the liquid composition passes from the tray through an orifice and then through an associated feed dropper where a droplet or liquid stream is formed. The orifices or combination of orifices and feed droppers will hereinafter be referred to collectively as feed assemblies.
The falling droplets of liquid composition freeze rapidly (i.e., flash freeze) in the freezing chamber due to the presence of both gaseous and liquid refrigerant in the area between the orifices and the bottom of the freezing chamber, thereby forming solid beads of flavored ice cream, yogurt or other alimentary products, such as flavored ice. More specifically, as droplets of liquid free fall through a gaseous region of the freezing chamber, and before the droplets contact the liquid refrigerant, the outer spheres of the droplets form a thin frozen shell. This thin frozen shell serves to protect the spherical shape of the droplets as they impact the surface of the liquid refrigerant. The remainder of the droplets freezes completely as they pass through the liquid refrigerant, and before reaching the bottom of the freezing chamber. The frozen beads are removed from the freezing chamber and packed for distribution and later consumption.
While the free-flowing, beaded ice cream that is prepared through the above-described flash-freezing process has enjoyed wide-spread popularity and success, it is believed that other unique novelty ice cream products may enjoy similar demand and success.
The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention, and together with the description serve to explain the principles of the invention. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the present invention. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views. In the drawings:
The present invention is directed to a novel frozen product and method for making the same, wherein a beaded frozen product, like that manufactured in accordance with U.S. Pat. No. 5,126,156, U.S. Pat. No. 5,664,422, or U.S. Pat. No. 6,000,229 are intermixed with conventional frozen product. The embodiment that will be described herein includes the incorporating of a beaded ice cream into a conventional ice cream product. However, consistent with the invention, the frozen product need not be ice cream, but may be yogurt, sherbet, or other alimentary products, such as flavored ice cream.
In this regard, the beaded ice cream may be intermixed with soft-serve ice cream on an individual serving basis, or may be intermixed with ice cream manufactured on a large scale production (e.g., packaged with ice cream conventionally sold in grocery stores). With regard to individual serving, beads of ice cream may be injected at a dispensing nozzle of machine for dispensing soft-serve ice cream. Alternatively, the beaded ice cream may be introduced into a reservoir of soft-serve ice cream and intermixed through a stirring or agitation process.
With regard to packaged ice cream, such as that purchased in grocery stores, beaded ice cream may be introduced into a conventional ice cream mix at a stage in the process where the non-beaded ice cream is still flowable such that the beaded ice cream may be stirred or agitated to mix and disperse relatively evenly throughout the ice cream product. Upon final freezing, the beads of ice cream, which retain their beaded form, will be intermixed and suspended throughout the ice cream product.
The present invention is directed not only to the final product, but also various methods of manufacturing the product. It will be appreciated that the introduction of beaded frozen product into a conventional ice cream product may enhance the conventional freezing process. For example, introducing a large number of beads at a much lower temperature (e.g., −175 degrees F.) will accelerate the freezing process by lowering the overall temperature of the mixture. It will also reduce the size of ice crystals formed in the conventional ice cream product.
Having summarized various aspects of the preferred embodiment, reference will now be made in detail to the description of the invention as illustrated in the drawings. While the invention will be described in connection with these drawings, there is no intent to limit it to the embodiment or embodiments disclosed therein. On the contrary, the intent is to cover all alternatives, modifications and equivalents included within the spirit and scope of the invention as defined by the appended claims.
Reference is made to
The product may be packaged in a half-gallon or larger container to provide multiple servings. As illustrated, the ice cream may have a conventional texture, with beads intermixed throughout the frozen ice cream product. In this regard, the beaded ice cream may be a flash-dash frozen product that is preferably manufactured in accordance with the teachings of U.S. Pat. No. 5,126,156, U.S. Pat. No. 5,664,422, or U.S. Pat. No. 6,000,229, or similar process. In accordance with the present invention, this beaded ice cream is evenly intermixed throughout an otherwise convention ice cream product.
As is known, and disclosed in the above-cited patents, the flash-frozen, beaded ice cream product, in order to maintain a free-flowing consistency to the beaded ice cream, it is preferably stored at temperatures well below zero F. It has been found that higher storage temperatures result in fusion of the beads, and thereby loss of its free-flowing consistency. For these reasons, ice cream made in accordance with the above-cited patents is generally not sold in grocery stores due to the inability of the conventional freezers to maintain sufficiently low temperatures.
However, it has been discovered that if the beaded ice cream product is solidified or frozen within a conventional ice cream product, that it need not be stored in such low temperatures, because the resulting product need not maintain a free-flowing consistency. What is important, however, for purposes of the preferred embodiment, is that the beaded ice cream product be introduced into the conventional ice cream product at a point in the processing where the beaded product may be uniformly mixed throughout the remaining ice cream product. However, the beaded product will not be introduced too early in the processing or manufacturing stage such that the beaded product would melt and loose the consistency of the identifiable beads. As illustrated in
One such method of producing a conventional ice cream containing a non-conventional beaded product would be to use a mechanism similar to a fruit and nut feeder (i.e., a mechanism used to mix fragments of fruit and/or nuts into ice cream products), which delivers product into the freezer barrel of a continuous conventional barrel freezer. The introduction of the cryogenic beads at −150 degrees F. into the conventionally frozen product in the barrel freezer (typically at approximately 28 degrees F.) causes the 28 degree F. ice cream to freeze faster, thereby reducing the size of the ice crystals and increasing the quality of the ice cream that was combined with the beaded product. U.S. Pat. No. 6,103,287 discloses a system and process which may be utilized to introduce the beaded product into an otherwise conventional ice cream, in accordance with one embodiment of the invention. The contents of this patent are incorporated herein by reference.
Reference is made briefly to
With regard to soft-serve ice cream, a variety of apparatus and dispensing machinery is knows for dispensing individual servings of ice cream. U.S. Pat. No. 6,250,794 and U.S. Pat. No. 6,318,889 illustrate illustrates two one such apparatus (both of which are incorporated herein by reference). In general, the apparatus for dispensing soft-serve ice cream includes a reservoir for containing a relatively large quantity of the ice cream product. A delivery mechanism, such as an auger or screw type conveyor may be provided for directing ice cream from the reservoir to a dispensing tap where it may be controllably dispensed in single serving quantities. One method for creating the product illustrated in
Alternatively, the beaded product 60 may be introduced into the injection nozzle 42 by spooning, pouring, or using another similar approach. In this regard, the beaded product 60 may be stored separately in a freezer that is configured to maintain a sufficiently cold temperature, so as to preserve the free-flowing characteristic of the product (i.e., to avoid beads being fused together). This supply of beaded product 60 may be accessed by a dispensing person to scoop, spoon, or other retrieve relatively small amounts of the product to introduce into the injection nozzle. Soft-serve ice cream is introduced into the dispensing portion of the apparatus and is delivered to an outlet through the action of the auger delivery mechanism 44. Beaded product introduced into the injection nozzle may be interspersed throughout the dispensed product through the agitating action of the auger delivery mechanism 44.
As illustrated in
In accordance with the invention, a separate reservoir or freezer compartment 60 may be provided for storing frozen beaded product to be mixed with the soft-serve ice cream product to be dispensed from apparatus 40. Preferably, the freezer compartment 60 will be maintained at a sufficiently low temperature as to preserve the free-flowing granularity of the beaded frozen product. A second delivery system (not specifically illustrated) may be proved to channel and introduce the beaded frozen produce into the delivery channel of the apparatus 40, such that the beaded frozen product is introduced into the soft-serve product at or near the point of dispensing.
In an alternative approach, one of more nozzles may be provided for injecting beaded ice cream into the reservoir of soft-serve ice cream. If a stirring mechanism, agitator, or other device is provided for periodically or continually mixing the soft-serve ice cream product within the reservoir, such a mechanism may be effective for intermixing the beaded ice cream product throughout. Such an alternative embodiment is illustrated in
As illustrated in
In connection with a conventional, larger scale ice cream manufacturing process, the introduction of the beaded ice cream into the conventional ice cream product is desired. Conventionally, ice cream is manufactured by mixing liquid ingredients in a mixing tank and feeding the mixed ingredients into a cooling unit where the mixed ingredients are reduced in temperature to about 20 degrees F. The mixed ingredients become significantly more viscous but will still flow. If the flavor being manufactured includes solid items, these solid items, such a cookie parts, are mixed into the flowing material at this point. This chilled and fully mixed material is fed to a package filling machine which feeds the material into the ice cream package. The ice cream package is closed and shrink wrapped to other packages for more convenient handling. The packaged ice cream is then placed in a hardening area for several hours where its temperature is reduced to zero or below for hardening. The packaged, finished ice cream is ready to be stored or shipped.
Indeed, a variety of methods, processes, and apparatus are known for manufacturing ice cream. U.S. Pat. No. 6,103,287, which is hereby incorporated by reference, discloses one such system and process. Consistent with the present invention, processes and apparatus such as the one described in U.S. Pat. No. 6,103,287 may be used, or other processes and apparatus may be used.
In one embodiment, conventional ice cream product is introduced into its shipping container in a semi-frozen state (e.g., in a soft or flowable form) and the container is introduced into a freezing chamber where it is frozen into a solid form for shipping and distribution. The beaded ice cream product is introduced into the semi-frozen ice cream product at or near the time the product is introduced into the shipping container. The beads of ice cream beaded product may be stirred or otherwise mixed into the semi-frozen product to achieve a reasonably uniform distribution throughout. As the filled containers later freeze solid, the product configuration illustrated in
