STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENTn/a
FIELD OF THE INVENTIONThe present invention relates to food processing machines and methods, and more particularly to a machine for preparing and dispensing edible frozen product and a method for making food products using the machine.
BACKGROUND OF THE INVENTIONMachines are known for processing and dispensing frozen dessert product such as soft-serve ice-cream and yogurt. Machines commonly used at retail establishments include a refrigerated chamber into which dessert mix is fed or pumped from a bucket or hopper. Blades or beaters churn the dessert mix to a desired consistency and the dessert mix is dispensed from a gravity-fed, manually-operated tap and allowed to flow into an open top cup or cone.
A different type of machine is disclosed in U.S. Pat. Nos. 5,957,040, 5,400,614; 5,957,040; 6,325,250; 6,485,768; and 6,723,361, all incorporated by reference, wherein an injection system is provided for extruding a selectable, predetermined volume of dessert mix. Further, the disclosed machine includes an injection nozzle that permits the dessert mix to be deposited within or injected into other than open containers or cones, such as into baked goods or other edible items.
Although the above referenced machines represent a significant departure from the known soft-serve ice-cream machines, they, like their predecessors, can be tedious and potentially unsanitary to operate and to clean. More specifically, known ice-cream machines must be very carefully cleaned as they process easily spoiled dairy products. Because known machines cannot retain usable dessert mix for an extended inactive period, not only does this waste dessert mix, but the known manual cleaning techniques are often incompletely or improperly performed by workers at the end of their shift. Further, refilling and restarting the machine can be tedious; and often the first batches of product produced are inconsistent and substandard in quality.
In view of these and other deficiencies of known machines, it would be desirable to reduce the frequency of filling, emptying and cleaning the machines; and when these procedure are accomplished, it would be preferable from a safety and quality standpoint to automate these procedures to the greatest extent possible. Further, it would be desirable to preserve dessert mix during extended inactive periods of operation.
Yet another shortcoming of existing machines is the inability to accurately dispense no more or less than a predetermined confection amount for a wide range of products. Further, existing machines do not provide usage and production detail that would be helpful in inventory controls, determination of shrinkage, and cost or royalty accounting.
SUMMARY OF THE INVENTIONThe present invention provides for a flowable edible product dispensing apparatus. The apparatus includes a programmable controller. An operator interface including an indicator of at least one edible item for selection is included, the operator interface is in communication with the programmable controller. A dispensing system in communication the operator interface is included, the dispensing system includes at least one nozzle operable to dispense at least one flowable edible product, the at least one nozzle being operable to penetrate the least one edible item. The programmable controller is operable to associate the at least one edible item with the least one flowable edible product. The dispensing system dispenses an amount of the at least one flowable edible product associated with the selected edible item from the at least one nozzle when the at least one edible item is selected.
In another embodiment, a method of dispensing flowable edible product includes presenting a visual indicator on a display and associating the visual indicator with at least one of an edible item and an inedible item and with a flowable edible product. The visual indicator is selected. At least a portion of at least one of the edible item and the inedible item is penetrated. The flowable edible product associated with the selected visual indicator is dispensed into a portion of at least one of the edible item and the inedible item.

A more complete understanding of the present invention, and the attendant advantages and features thereof, will be more readily understood by reference to the following detailed description when considered in conjunction with the accompanying drawings wherein:
The present invention provides a dispensing apparatus 10 for dispensing or injecting a flowable edible product into an item having a void or voids therein, or an item having low density suitable for receiving a flowable edible product. Such items may include pastries, baked goods, fruit, chocolate shells, as well as containers or beverage bottles. As used herein, the term “frozen edible product” is intended to encompass a cold, edible, and flowable substance such as ice cream, ice milk, yogurt, pudding, artificial edible product which generally has the consistency of “soft serve” ice cream.

In addition, the electrical system may include a communication card or device that allows the apparatus 10 to both send and receive electrical signals across a network either through a fixed medium or wirelessly, as well as a data storage device including electrical, magnetic, and/or optical storage devices and medium. For example, the apparatus 10 may include an ethernet card and/or wireless transceiver coupled to the PLC for communication therewith. The electrical system may be coupled to an optical sensor or other proximity activation element for initiating an extrusion cycle, as described below. Alternatively, a foot pedal or other suitable actuating mechanism may be integrated to initiate dispensing or injection of the edible product.
The refrigeration system may generally include a pressure switch, cooling coils, a compressor, a hot gas mixing valve and a water pressure regulator. In the event a portion of the refrigeration system exceeds a predetermined or desired temperature, gas pressure may increase and thereby damage components of the apparatus 10. To prevent such an event, the pressure switch may convey an indication of the temperature and/or pressure to the PLC, which may subsequently initiate a shut-down of one or more processes of the apparatus 10, which may further include a visual indicator on the operator interface. The cooling coils may be integrated to cool hot gas created by the compressor, where the compressor may be operated to cool one or more chambers storing or containing the frozen edible product. The hot gas mixing valve may control or otherwise monitor the flow of gas through the apparatus 10, while the water pressure regulator may provide water flow through a portion of the system in proportion to the temperature and/or current operating parameters of the apparatus 10. In particular, the hot gas valve may be controlled by an electronic circuit board in communication with the PLC and/or an analog input/output card. The beater motor amperage may be monitored as the input parameter for regulating the hot gas valve position. As hot gas is required to warm the product chamber, the PLC may signal the circuit board to open or close the hot gas valve to maintain a predetermined or preset amperage of the beater motor. By regulating the temperature of the chamber based on the amperage or operating condition of the beater motor, the frozen product is more likely to have a consistent texture and temperature, thereby ensuring repeatable quality of the product. Typical machines of the prior art often rely on a chiller or compressor to turn on and off at a particular time, where such timed operation decays as the system ages and result in inconsistent product conditions.
In addition, the refrigeration system may further include a mix chamber for mixing and/or otherwise processing a frozen edible product mixture into the desired state, where the mix chamber may be coupled to a thermostat, a mix chamber compressor, a mix chamber condenser, as well as a standby thermostat. The mix chamber thermostat may monitor and/or maintain the mix chamber temperature at or below a predetermined threshold at which the frozen edible product may be dispensed, while the mix chamber compressor provides the cold air that chills or otherwise provides for a desired temperature of the mix chamber. In addition, the mix chamber condenser allows heated gasses created by the compressor to cool and run back into the compressor for subsequent cooling of the mix chamber. The standby thermostat may activate a chilling cycle when the apparatus 10 is placed in a standby mode. For example, once the mix chamber reaches a predetermined threshold, the thermostat may signal the PLC to activate the compressor until a particular temperature is reached, upon which the operation of the compressor will cease until needed again.
The product preparation system of the apparatus 10 of the present invention may generally include a mixing pump, a mixing pressure switch, a beater motor, a mixing pump motor, one or more pulleys and belts, and one or more level probes. The apparatus 10 is capable of dispensing soft-serve ice cream into open containers or can inject a frozen edible product, such as hard ice cream, into an edible item. The mix pump may generally pump a liquid product used in preparation of the frozen edible product into a refrigeration chamber or mix chamber. When the mix pump has filled the chamber receiving the liquid product, the flow of the liquid product may activate a switch in the holding or mixing chamber, where the switch is activated at a predetermined pressure level to send a signal to the PLC, which subsequently discontinues pumping once the chamber has been filled to a particular level. The beater motor may be mechanically connected to a gearbox by the one or more pulleys or other similar mechanical coupling, where the gearbox is further coupled to a beater bar unit inside the product chamber. The motor causes the stiffing of the bar while the liquid product is being chilled. To obtain a particular temperature and/or consistency of the frozen edible product being prepared in the mix chamber, the output or speed at which the beater motor is operating may be used as in indication or measure of the consistency and/or readiness of the product to be dispensed. Upon appropriate freezing of the product and/or once the product reaches a desirable temperature for dispensing, it may be moved towards a portion of the chamber predisposed for dispensing. The level probes of the product preparation system may indicate when the mixing container has reached a low level, which may also be used to initiate a filling sequence by which additional liquid product is moved to the mixing container.

The operator interface 16 may include programmed procedures, protocols and/or other operating parameters to ease use of the apparatus 10, as well as to remove the likelihood for operator error or inconsistencies which could lead to substandard product preparation. For example, the operator interface may include automatic, preset procedures for initial apparatus 10 startup, product dispensing, apparatus 10 cleaning cycles, and/or hibernation or “overnight” modes by which the apparatus 10 may operate, as illustrated in the simulated visual displays of
In addition to inconsistencies in product preparation, previous dispensing machines would also vary widely in the actual amount of product dispensed, as the dispensing was typically controlled manually by an operator, i.e., by pulling a lever or the like. As a result, the actual amount or volume of dispensed product could be directly affected by the operator. The apparatus 10 of the present invention may include nozzles and/or plungers as described above that are either electrically or pneumatically controlled to travel a preset distance, thereby dispensing a uniform and accurate volume or amount of product. Moreover, the operator interface may include a menu of items, where each of the items available for use with the dispensing apparatus 10 have a predetermined, preset amount or volume of dispensed product associated with them. For example, the operator interface may include a display for an LCD or touch screen having a plurality of available edible products illustrated, where each of the available product has a predetermined volume or amount of frozen product associated with it. The preset, predetermined frozen edible product amounts correlating to a particular edible product for use with the apparatus 10 may be stored in the memory of the PLC. Moreover, the preset volume or amount of frozen edible product may further include parameters for operating the nozzles and/or plungers of the apparatus 10 to actually dispense the predetermined amount. For example, upon selecting a desired product from the menu, the PLC may then convey a signal to the nozzles and/or plungers to move a preset distance and/or to dispense for a preset amount of time, thereby providing a consistent, desired volume time and time again for a given product.
For cleaning of a particular dispensing machine, a protocol or procedure having various manual steps may typically be required. For example, instructions for cleaning may include such steps of “turn off refrigeration,” “replace mix container with water or cleaning solution,” “cycle nozzles/plungers until water exits nozzles,” etc. Similar to the product preparation stage, the efficacy and/or thoroughness of a particular cleaning cycle may vary widely depending on the accuracy of an operator to follow the instructions and complete each step as described. With respect to the present apparatus 10, the particular parameters and/or settings with which the components of the apparatus 10 should operate to properly and thoroughly clean the apparatus 10 may be preprogrammed and/or saved in the memory of the PLC. As such, an operator need only actuate a cleaning cycle via the operator interface, which may simply include a single button on the touch screen. Once actuated, the preset program may run, i.e., refrigeration may be deactivated, the nozzles and/or plungers may be cycled to dispense unused frozen product for a predetermined period of time, the beater motor may be deactivated, etc. As a result, an optimal, predictable and repeatable cleaning procedure may be easily performed, regardless of operator efficiency or skill.
The dispensing apparatus 10 may further include a standby mode in which it is not necessary for the machine to have frozen product ready for dispensing for a prolonged period of time (i.e., overnight, days when store is closed, etc.). In this standby or hibernation mode, the beater motor may be deactivated so that any mix in the mixing container is not being agitated. Moreover, the refrigeration system may be set to a temperature higher than that of normal operating conditions when frozen edible product is being made, but remaining low enough that the ingredients in the apparatus 10 do not risk being spoiled or contaminated due to warmth. As such, the apparatus 10 may remain in this standby mode for a prolonged duration without the need to clean the machine and without spoiling or contamination. In addition, by modifying the temperature requirements and ceasing operation of the beater motor, the apparatus 10 will thereby consume less energy and/or water compared to when the apparatus 10 is in normal operation. Once normal operation of the apparatus 10 is again desired, the apparatus 10 may simply purge the cooled ingredients and draw fresh mix into the mixing container for preparation of a fresh batch of frozen edible product. Subsequently, the refrigeration system may once again lower the temperature to an appropriate production level, and the beating motor will be activated as well. The standby mode allows the apparatus 10 to reach production quicker than would otherwise be possible if the apparatus 10 was simply shut down completely, which would also necessitate cleaning and therefore involve a longer downtime.
The operator interface may further include visible indicators of the status and/or condition of the various operating parameters of the apparatus 10, including data regarding time of use, product temperature, mix levels, and/or diagnostic information regarding particular components of the apparatus 10. For example, the operator interface may include a beater status display listing the rpm or amperage of the beater motor, as well as the setpoints or targets at which the beater and/or motor should operate. In addition, should a particular component of the apparatus 10 being operating outside of a predetermined parameter or range, or cease to operate at all, the operator interface may provide a visual signal or indication of a system malfunction or error.
During typical use, frozen product may proceed from the mixing chamber to the manifold chambers until dispensing is commenced. An operator may select a desired product from the menu shown on the operator interface. Upon selection of the desired item, the apparatus 10 may correlate the selection to a predetermined volume or amount of frozen edible product to be dispensed, and the PLC may convey appropriate control signals to the components of the apparatus 10 to in preparation of dispensing the predetermined amount. Once dispensing is desired, the operator may actuate the optical or proximity sensor. The PLC and/or electrical system detects activation of the sensor and causes nozzles and/or plungers to be energized for a predetermined amount of time or to travel a preset distance, where the time and/or distance corresponds to a selected volume of frozen edible product to be extruded from the machine. In a single-stroke embodiment, the nozzle plunger retracts than extends, thereby dispensing the predetermined amount of frozen product associated with the selected item out of the nozzle. The nozzle plunger may be actuated pneumatically or electrically, and may include a tapered or bullet-nose shaped tip to ease the piercing of certain edible products. In a two-stroke embodiment of a dispensing apparatus 10, horizontal and vertical plungers may be pneumatically or electrically retracted for a specific, predetermined amount of time, thereby setting a specific amount of frozen product to be dispensed. During and/or after activation of the plungers, the PLC may energize the mix pump to cause mix to flow from the mix receptacle to the mixing chamber to replace the dispensed amount of frozen product.
Throughout the use of the apparatus 10, various information regarding the time of use, quantities distributed, particular status of the various components, and the like of the apparatus 10 may be recorded and stored in the memory of the apparatus 10, and may further be transmitted via the communication device to a central clearinghouse and/or corporate entity for review and analysis. In addition, the trends and indicated uses of the apparatus 10 may be used in establishing a supply schedule or the like for optimal incorporation and use of the apparatus 10 for a particular business.
In addition to the above embodiments, the dispensing apparatus 10 may further be used to dispense flowable edible products, such as sodas, fresh or frozen yogurts, smoothies, or other foods into, on, or within inedible items such as plastic or paper cups, plastic containers, such as bottles, glass containers, or other items sized to receive a portion of the flowable product. For example, using the methodology and apparatus discussed above, yogurt may be dispensed, deposited or injected into a cup for consumption. The amount of edible product deposited within or on the inedible product may be predetermined as discussed above or may be manually determined by the operator. For example, a lever may be manually operated by the operator to dispense an amount of yogurt into a cup, or alternatively, actuating the operator interface may dispense either a predetermined amount of yogurt or an operator specified amount of yogurt into a cup depending upon the order from the customer. If an edible product such as an ice cream cone is selected, the nozzles of dispensing apparatus may penetrate the air space within the cone to deposit or inject the flowable edible product within the interior of the cone or a cup in an inedible product is selected.
The operator interface 16 may further display one or more inedible item images, for example, a container such as a cup or bottle, with one or more volumes of each. For example, 6 oz or 16 oz cup may be displayed and selected by the user for the flowable edible product to be dispensed into. Optionally, the operator interface may include both visual and audio indicators of edible and inedible items to be selected. For example, the operator interface may include a speaker which audibly identifies which products, edible or inedible are available for selection. Additionally, operators may selection items for selection by speaking the particular edible or inedible item for selection. For example, the operator may state “cone” and “strawberry yogurt” for selection whereby the dispensing apparatus may dispense a predetermined or operator selection amount of strawberry yogurt into the cone.
Optionally, the operator interface may be in communication with the programmable controller through a wireless remote controller with a wireless transmitter for communication with the programmable controller. For example, the operator interface on the remote control may include indicators such as numbers, images, or other indicators on a display on the remote control, which may include a keypad with push buttons or touch screen activators. The same display may also be included on the display of the dispensing apparatus, which indicates a particular edible and inedible item for selection. When a particular edible or inedible item is selected, the remote controller signals the dispensing apparatus to dispense a predetermined amount flowable product into the selected edible and/or inedible item.
