The present disclosure relates to technology for producing frozen cocktail ice structures.
In the current state of the art it is difficult to produce a cocktail ice structure (e.g. an ice cube) that can be easily used for making a drink, e.g. a margarita, a smoothie or any other drink type. One challenge with refreezing or “enrobing” ice cubes is that ice typically fractures below sub-zero temperatures. Due to the fracture, ice chunks are created that may not be suitable for preparing a cocktail drink. Continuous efforts are being made to develop technology for efficiently producing cocktail ice structures that can easily be used to make a cocktail drink, without fracturing the ice during the cocktail ice structure production process.
In one aspect of the present disclosure, a method for producing a frozen cocktail ice structure is provided. The method includes: setting a temperature of an interior surface of a tumbler below a desired temperature for an ice structure loaded into the tumbler; executing a sauce coating cycle for coating the ice structure with a sauce; executing a freeze cycle after the sauce coating cycle, by spraying nitrogen on the ice structure; alternating between the sauce coating cycle and the freeze cycle for applying sauce on the ice structure; and executing a water cycle for applying water on the ice structure coated with the sauce to produce a frozen cocktail ice structure.
In another aspect, a system is provided. The system includes a tumbler for receiving at least one ice structure; and a controller having a processor executing instructions out of a memory for: alternating a sauce coating cycle that applies a sauce layer on the ice structure and a freeze cycle that occurs after the sauce coating cycle to spray nitrogen on the ice structure; and executing a water cycle for applying water on the ice structure coated with sauce for producing a frozen cocktail ice structure having sauce coated on the ice structure.
In yet another aspect, a frozen cocktail ice structure is provided. The frozen cocktail ice structure includes an ice structure coated with a plurality of sauce layers. The ice structure is coated with a first sauce layer during a sauce coating cycle, and after the sauce coating cycle, nitrogen is sprayed on the ice structure during a freeze cycle. The sauce coating cycle and the freeze cycle alternate for applying a plurality of sauce layers and nitrogen on the ice structure; and after a last freeze cycle, water is applied on the ice structure coated with the plurality of sauce layers.
The foregoing features and other features will now be described with reference to the drawings of the various aspects of the present disclosure. In the drawings, the same components have the same reference numerals. The illustrated aspects are intended to illustrate, but not to limit the present disclosure. The drawings include the following Figures:
In one aspect, innovative technology is provided for efficiently producing frozen cocktail ice structures. The technology enables application of different ingredients as “sauce layers” on ice structures during a sauce coating cycle. A freeze cycle applies nitrogen on the ice structure coated with one or more sauce layers. The sauce coating and freeze cycles alternate until a desirable number of sauce layers have been applied. A water cycle applies water on the ice structure coated with the frozen sauce. The ice structures with the sauce maybe used to make a drink. The following describes the innovative systems and processes for manufacturing the frozen cocktail ice structures.
System 100:
In one aspect, system 100 includes: (i) a sauce tank 104 where sauce raw materials 102 are mixed, (ii) a sauce feed pump 106 that pumps sauce 120 from sauce tank 104, (iii) an ice supply unit 108 that supplies ice 126, (iv) a nitrogen supply unit 114 that supplies nitrogen 122, and (v) a water supply unit 118 that supplies water 118. The sauce 120, ice 126, nitrogen 122 and water 124 are provided to a tumbler system 110 in a sequence, as described below in detail with respect to
The operations of these various components, namely, the sauce tank 104, sauce feed pump 106, ice supply unit 108, water supply unit 118, the nitrogen supply unit 114, and the tumbler system 110 is controlled and managed by a program logic controller (PLC) 112, as described below in detail.
In one aspect, as an example, the sauce tank 104 is configured to receive the sauce raw materials 102. The sauce raw materials 102 vary based on a recipe. As an example, the sauce tank 104 maybe a 1400 gallon (i.e. 194 cube inch), stainless steel tank with a coned bottom and 2″ outlet. The sauce tank 104 may include a stainless-steel high shear mixer operating at about 1750 RPM (revolutions per minute), using 3 phase, 480 volt. It is noteworthy that the sauce tank 104 specifications are simply shown as an example and other sauce tank specifications/configurations may be used for executing the innovative process blocks of the present disclosure described below in detail.
In another aspect, the sauce tank 104 is operationally coupled or connected to the sauce feed pump 106. The sauce 120 based on the sauce raw materials 102 is pumped from the sauce tank 104 by the sauce feed pump 106 into the tumbler system 110, as described below. As an example, the sauce feed pump 106 may be a Graco SaniForce Model 1040 pump (without derogation of any third-party trademark rights) available from Graco Corp. The pump may have the following specifications: a flow rate 40 GPM (gallons per minute) with a maximum fluid press of 120 PSI (pounds per square inch); suction lift (wet) up to 29 feet; maximum solids of ⅛″; maximum viscosity of 10,000 CPS (centipoise); and compressed air supply 100 CFM (cubic feet per-minute) at 125 PSI. It is noteworthy that the sauce feed pump 106 specifications are simply shown as an example and other pump specifications/configurations may be used for executing the innovative process blocks of the present disclosure, described below in detail.
In yet another aspect, nitrogen 122 from the nitrogen supply unit 114 is provided to the tumbler system 110, as described below in detail. As an example, the nitrogen supply unit 114 may include an 11000-gallon storage tank, a 120-volt control valve and a 50 PSI stabilization system and liquid pressure controls. It is noteworthy that the nitrogen supply unit 114 specifications are simply shown as an example and other specifications/configurations may be used for executing the process blocks of the present disclosure.
In one aspect, as an example, the tumbler system 110 is a Gunther, tumbler, Model 2200 (without derogation of any third-party trademark rights) designed and manufactured by Gunther-Maschinenbau Corp. The tumbler system 110 includes a configurable control system (e.g. PLC Pilz model Pnoz mlp); has a capacity of 800-1000 pound and is configured to operate at 208 volt. The tumbler system 110 is configured with inlets to receive sauce 120 from the sauce feed pump 106, nitrogen 122 from the nitrogen supply unit 114 and water 124 from the water supply unit 118, as described below in detail. It is noteworthy that the tumbler system 110 specifications are simply shown as an example and other tumbler system specifications/configurations may be used for executing the innovative process blocks of the present disclosure, as described below in detail.
In one aspect, sauce raw materials 102 are poured and mixed at the sauce tank 104. The sauce raw materials are based on a recipe for a drink, and hence will vary based on the type of drink. The adaptive aspects of the present disclosure are not limited to any specific recipe or any specific type of drink. The sauce raw materials 102 are mixed in sauce tank 104 for a certain duration and provided to the sauce feed pump 106. The duration for mixing the sauce depends on the drink type.
The ice supply unit 108 provides ice 126 that is placed in the tumbler system 110. Ice 126 may include ice cubes, cylindrical shaped solid ice structures, hollow cylindrical shaped ice structures, solid cone shaped ice structures, irregular shaped ice structures or any other shape of ice structures. The adaptive aspects of the present disclosure are not limited to any specific shape or ice structure size. Before ice 126 is placed in the tumbler system 110, the tumbler system 110 goes through a pre-frost/freeze process. During this process, as an example, the temperature of the inside of the tumbler system 110 is set to about −80 degrees Fahrenheit. Ice 126 is kept in the tumbler system 110 for a certain duration (e.g. 15 minutes) such that the surface temperature of ice 126 is within a certain range, e.g. 0 to −3 degrees. Once a desirable surface temperature of the ice structure is reached, a coating process is executed, as described below in detail.
Briefly, the coating process involves alternating micro-cycles, during which the sauce 120 from the sauce feed pump 106 and nitrogen 122 from the nitrogen supply unit 114 are applied to ice 126 within the tumbler system 110. Applying the sauce 120 is referred to as the “sauce cycle” and applying nitrogen is referred to as the “freeze or frost cycle”. Once the coating process is complete, the coated ice structures (e.g. cubes) are exposed to water 124 from the water supply unit 118 to encapsulate the ice structures. This makes the coated ice structures easier to pack and transport. This also prevents the ice from breaking when a drink is prepared. Details regarding the process steps of the present disclosure are provided below with respect to
Process Flow:
In block B204, the tumbler system 110 interior surface is set to a certain temperature, e.g. −80 degrees Fahrenheit. In block B206, ice 126 from the ice supply unit 108 are loaded into the tumbler system 110 for an ice tempering process. During the ice tempering process, ice 126 is kept stationery in block B208 for a certain duration, such that the surface of ice 126 reaches a certain temperature, e.g. between 0 to −3 degrees Fahrenheit. The ice surface temperature is verified in block B210, before a coating process can begin in block B212.
During the coating process, sauce 120 and nitrogen 122 are applied to ice 126 in alternating cycles referred to as micro-cycles. The sauce application is referred to as the sauce cycle, and the nitrogen application is referred to as the freeze cycle. The tumbler speed during the sauce cycle is about 18% at 15 rpm (revolutions per minute), and the tumbler speed during the freeze cycle is about 10% at 15 rpm. The adaptive aspects of the present disclosure are not limited to any specific tumbler speed.
During the freeze cycle the ambient temperature within the tumbler system 110 is maintained at about −30 degrees Fahrenheit, while the temperature of the ice 126 is maintained between −7 to −25 degrees Fahrenheit. The adaptive aspects of the present disclosure are not limited to any specific temperature.
As an example, the sauce cycle includes 1.05 pounds per second of sauce spray within a 12 second cycle. The sauce cycle includes 2.6% of sauce per cycle for about 25-30 sauce cycles. As an example, the freeze cycle includes 0.06 pounds per second of nitrogen spray with a 30 second cycle time. The sauce and freeze cycles are repeated until the sauce 120 has been consumed.
Once the coating process is completed, in block B214, a water cycle is executed when water 124 is injected into the tumbler system 110 from the water supply unit 118. As an example, the water cycle includes 0.8 pound per second of water spray with a cycle time of 12 seconds. The water cycle includes about 4.6% of water per cycle for about 21-22 cycles. Once the water cycle is completed, the frozen cocktail ice structures are output and packaged in block B216.
In one aspect, the technology disclosed herein enables coating an ice structure with ingredients for a cocktail or any other type of drink. The ice structures are not fractured, hence the sprayed sauce 120 remains in a frozen solid state. A user can simply unpack the frozen cocktail structures with the sprayed ingredients, place the frozen cocktail ice structures in a shaker (not shown), add liquor (or any other content), and then shake the contents in the shaker. Upon shaking, the sauce coating from the ice structures comes off, while the ice structures stay intact in the cocktail. As an example, a user could also use a blender to make a cocktail with the frozen cocktail ice structures. The adaptive aspects disclosed herein are not limited to using the shaker, blender or any other equipment type.
PLC 112: In one aspect, PLC 112 manages the various settings and controls for the sauce tank 104, the sauce feed pump 106, the tumbler system 110, the nitrogen supply unit 114 and the water supply unit 118. Processor executable instructions for controlling the various components of system 100 may be stored, for example, at a non-transitory, computer readable media including, but not limited to, an ASIC (application specific integrated circuit), CD (compact disc), DVD (digital video disk), ROM (read only memory), floppy disk, hard disk, EEPROM (electrically erasable programmable read only memory), solid state drive, memory stick or any other storage media, in accordance with the claimed subject matter.
In one aspect, PLC 112 includes one or more processors 302 and a memory 304, coupled to a bus system 305. The processors 302 are the central processing units (CPUs) and, thus, control PLC 112's overall operation. In certain aspects, the processors 302 accomplish this by executing programmable instructions stored in memory 304. As an example, processors 302 of PLC 112 may be, or may include, one or more programmable general-purpose or special-purpose microprocessors, digital signal processors (DSPs), programmable controllers, application specific integrated circuits (ASICs), programmable logic devices (PLDs), or the like, or a combination of such devices.
Memory 304 of PLC 112 represents any form of random-access memory (RAM), read-only memory (ROM), flash memory, or the like, or a combination of such devices. The memory includes the main memory of PLC 112. Instructions 306 which implement the techniques of
PLC 112 may include one or more internal mass storage device 310 and a network adapter 312. Internal mass storage device 310 may be or may include any conventional medium for storing data in a non-volatile manner, such as one or more magnetic or optical based disks, storage class memory, solid state drives or any other storage media. The network adapter 312 provides the PLC 112 with the ability to communicate with remote devices (e.g., storage servers) over a network and may be, for example, an Ethernet adapter, a FC adapter, or the like.
The PLC 112 also includes one or more input/output (I/O) devices 308 that may include, for example, a display device, a keyboard, a mouse, or any other device for receiving input/output commands for managing process 200.
In one aspect, methods and systems for producing cocktail ice structures are provided. One method includes setting a temperature of an interior surface of a tumbler below a desired temperature for an ice structure loaded into the tumbler; executing a sauce coating cycle for coating the ice structure with a sauce; executing a freeze cycle after the sauce coating cycle, by spraying nitrogen on the ice structure; alternating between the sauce coating cycle and the freeze cycle for applying sauce on the ice structure; and executing a water cycle for applying water on the ice structure coated with the sauce to produce a frozen cocktail ice structure.
In another aspect, a system is provided. The system includes a tumbler for receiving at least one ice structure; and a controller having a processor executing instructions out of a memory for alternating a sauce coating cycle that applies a sauce layer on the ice structure and a freeze cycle that occurs after the sauce coating cycle to spray nitrogen on the ice structure; and executing a water cycle for applying water on the ice structure coated with sauce for producing a frozen cocktail ice structure having sauce coated on the ice structure.
In yet another aspect, a frozen cocktail ice structure is provided. The frozen cocktail ice structure includes an ice structure coated with a plurality of sauce layers. The ice structure is coated with a first sauce layer during a sauce coating cycle, and after the sauce coating cycle, nitrogen is sprayed on the ice structure during a freeze cycle. The sauce coating cycle and the freeze cycle alternate for applying a plurality of sauce layers and nitrogen on the ice structure; and after a last freeze cycle, water is applied on the ice structure coated with the plurality of sauce layers.
