Patent Application
20130316062
The present application generally relates to a food product and more particularly relates to a method for creating an aerated food product which may utilize a smaller thermal and electrical load upon the equipment used in the production process.
Conventional food preparation methods of commercially produced aerated food products may typically be created by combining all of the ingredients together, followed by heat treating and homogenization, then cooling the product prior to aerating it. One of the potential drawbacks of this method is the large amount of electrical and thermal load which may be necessary to process the resulting food product prior to aerating it because it may be more viscous in nature, therefore requiring more energy to move the product through the necessary machinery. As a response to these limitations, the method described herein discloses how to reduce the electrical and thermal load necessary to process and create aerated food products, particularly demonstrated using an aerated Mousse as an example. Through the separation of the Mousse base ingredients and the gelatin solution into less viscous counterparts at cooler temperatures, a decreased electrical and thermal load may be needed to process the separate components at the desired temperature prior to combining and aerating them. It is desirable to reduce electrical and thermal loads because some manufacturing plants may be incapable of supporting conventional processing methods. Some manufacturers may realize cost savings by decreasing energy expenditure, and some manufacturers may be incapable of affording the necessary equipment to use traditional commercial methods.
Thus, a need exists for an apparatus and method capable of creating an aerated food product, system, and method under conditions that may be unable to support the conventional commercial production apparatuses and methods.
A first general aspect relates to a system for creating an aerated food product, whereby a decreased electrical and thermal load may be obtained, the system comprising a first aseptic surge tank configured to receive a first food product portion, a second aseptic surge tank configured to receive a second food product portion, a mixer connected to the first aseptic surge tank and the second aseptic surge tank, the mixer configured to mix the first food product portion and the second food product portion to create a mixed food product, and an aerator connected to the mixer, the aerator configured to aerate the mixed food product to create the aerated food product.
A second general aspect relates generally to a method of producing an aerated food product comprising the steps of separately preparing a first food product portion and a second food product portion, transferring the first food product portion to a first aseptic surge tank, transferring the second food product portion to a second aseptic surge tank, mixing a combination of the first food product portion and the second food product portion to create a mixed food product, aerating the mixed food product to create the aerated food product, and dispensing the aerated food product from a filling apparatus into a container. By separating the first food product portion from the second food product portion, a decreased electrical and thermal load may be achieved because a combined food product may be much more viscous than separated portions blended at a later processing stage. A viscous food product may require greater pump energy to move the product and increased motor loads. Conversely, a separated food product may be much less viscous therefore decreasing pump energy and motor loads may be needed to move product or process the product.
A third general aspect relates generally to an aerated food product comprising a first food product portion; and a second food product portion, wherein the first food product portion and the second food portion are separately aseptically prepared and combined in a mixer, and aerated to create the aerated food product.
Some of the embodiments will be described in detail, with reference to the following figures, wherein like designations denote like members, wherein:
A detailed description of the hereinafter described embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures. Although certain embodiments are shown and described in detail, it should be understood that various changes and modifications may be made without departing from the scope of the appended claims. The scope of the present disclosure will in no way be limited to the number of constituting components, the materials thereof, the shapes thereof, the relative arrangement thereof, etc., and are disclosed simply as an example of embodiments of the present disclosure.
As a preface to the detailed description, it should be noted that, as used in this specification and the appended claims, the singular forms “a”, “an” and “the” include plural referents, unless the context clearly dictates otherwise.
Throughout the specification, references to percentages are by weight and temperatures are in degrees Fahrenheit unless otherwise indicated.
System 100 may achieve the decreased electrical and thermal load by separating portions of matter desired to be combined into a plurality of surge tanks, such as a first surge tank 103 and a second surge tank 109. By separating the first food product portion from the second food product portion, a decreased electrical and thermal load may be achieved because a combined food product may be much more viscous than separate components blended at a later processing stage. A viscous food product, once cooled may require greater pump energy to move the food product and increased motor loads, typically requiring a larger powered pump to work with the highly viscous products. Conversely, separating a food product into first and second food product portions may be much less viscous therefore decreasing pump energy and motor loads may be needed to move product or process the product. Discharge from a surge tank for low viscous products is typically accomplished by pressurizing the vessel. Separation is not limited to two surge tanks, for example, there may be any number of surge tanks used for containing materials desired to be combined into a final product. Embodiments of the first surge tank 103 and the second surge tank 109 may be pressurized aseptic surge tanks promoting a sterile environment within the tank and capable of being in contact with food product(s). Surge tanks 103, 109 (sometimes referred to as “surge drum”) may be used to regulate one or more fluid levels in the system 100. Regulation of fluids entering through the first surge tank inlet 101 and the second surge tank inlet 110 may be regulated by varying the flow rate from the thermal processors upstream of first intake valve 102 and a second intake valve 111. Intake valves 102, 111 may be a flow regulator, flow controller, or similar device that can be used as a means for regulating the flow of fluid in which the flow rate may be user controlled. Surge tanks 103, 109 may act as storage reservoir which supplies excess fluid when necessary to the rest of the system 100. Surge tanks 103, 109 may have the ability to modify flow rate through a first output valve 106 operably associated with the first surge tank 103 and a second output valve 113 operably associated with the second surge tank 109. The output valves 106, 113 may be a flow regulator, flow controller, or similar device that can be used as a means of controlling fluid output, which may be user controlled. The first and second surge tanks 103, 109 may also be connected to a first pump 108 and a second pump 115, respectively. The pumps 108, 115 may propel the contents of the first and second surge tanks 103, 109 to a desired location at a desired rate by varying the speed of pumps 108 and 115; these may be relatively small powered pumps compared to pumps used under conventional processing methods. Pumps 108 and 115 may be non-slip pumps so as not to interfere with the controls of the aeration device 122. Embodiments of pump 108, 115 may vary depending on the contents of the surge tanks 103, 109. For instance, the first pump 108 may be a rotary lobe pump used when the contents of the first surge tank 103 contain thick viscous materials, solids, semi solids or slurries. Embodiments of the second pump 115 may be a progressive cavity pump 115 used when the second surge tank 109 contains liquids or compounds in solution. Those having skill in the requisite art should understand that system 100 is not restricted to these particular pumps, and any pump capable of being connected to a surge tank may be used.

Moreover, embodiments of the first surge tank 103 and the second surge tank 109 may include a means to control pressure within the tanks 103, 109. Pressure within the first tank 103 may be controlled by an external sterile air supply (not shown in
With continued reference to
A means for combining surge tank streams in metered proportions may include equipping each surge tank 103, 109 with outputs 107, 111, which may be a pipe, tubing, hoses or other commonly known methods for displacing fluid or semi-solids within a controlled fashion, through the use of valves 106 and 113 and/or pumps, such as a rotary lobe pump 108 or a progressive cavity pump 115. The streams can be combined by linking the surge tank pipes, tubing, hoses or other known fluid displacement methods into a common location capable of holding the contents of both surge tank streams, such as mixer 117. Alternatively, if mixing is not required, the contents of the surge tanks may flow directly into an aerator 122 or any other container capable of holding the desired contents.
Once the contents of the first and second surge tanks 103, 109 have been combined, the contents of the mixer 117 may then be expelled via the mixer's output means 118. The output means 118 for a mixer may be any means capable of displacing the contents of the mixer to a desired location. For instance, the output means 118 may be piping, tubing, and the like, physically connecting the mixer 117 and the aerator 122. These means may be similar to the means through which the surge tanks 103, 109 expel their contents. The contents of the mixer 117 may be expelled into an aerator 122.

The amount of aeration of the mixed product located within the aerator 120 may be referred to as “percent overrun.” Percent overrun may be calculated by ((unaerated base weight−final aerated weight)/final aerated weight)×100. For example an aerated product (e.g. final food product) containing an unaerated base weight of 115 g and a final aerated weight of 65 g will have a percent overrun of ((115−65)/65)×100=77%. Additionally, the percent overrun may have a variation of approximately 20%.
Embodiments of system 100 may further include a filling apparatus 127 connected to the aerator 122, the filling apparatus configured to receive the aerated food product from the aerator 122 and insert the aerated food product into a package or container. Embodiments of the aerated food product may be the final food product inserted into packages and containers for distribution and consumption. Specifically, once the aerated food product has reached a desired percent overrun, the aerated food product can be transferred to the filling apparatus 127 via an aerator output connection 123, which connects the aerator 122 to the filling apparatus 127 maintains fluid communication therebetween. Embodiments of the aerator output connection 123 may include a purge valve 124, or any other known means for a user to bleed a system. A purge valve, such as purge valve 124 may be used to bleed the system of contents (e.g. the food product(s)) prior to reaching the filling apparatus 127. Furthermore, embodiments of system 100 may have any multiple numbers of purge valves along its path and in various locations. A purge valve, such as purge 124, allows the user access to the contents of the system 100 at a point prior to the system's completion proximate the filling apparatus 124.
Embodiments of the filling apparatus 124 may be a machine capable of inserting food products, such as the aerated food product transferred from the aerator 122, into packaging or containers. For example, embodiments of the filling apparatus 127 may be a Hamba Filler, Hamba Cup Filler, and the like. Furthermore, embodiments of the filling apparatus 127 may be able to sterilize and seal the packaging and/or containers receiving the aerated food product, or other final food product. The packaging and/or containers may be composed of any known plastic, Styrofoam, glass, porcelain, cardboard or any other known packaging material formulations used in the food industry. Packaging or containers can come in various shapes, volumes, designs, and sizes depending on various needs. For example, the packaging and/or container receiving the aerated food product, or other final food product, can be a 4 oz. individual portion cup. Moreover, embodiments of the packaging and/or containers may be sealed with a “heat seal.” Heat seals may be defined as a method for enclosing products in wrapping or packaging wherein an airtight seal is created by applying an external amount of energy such as heat to melt the sealant, followed by applying pressure to fuse the edges of the wrapping together. Heat seals may include, but are not limited to, such examples constructed out of aluminum or plastics.

It may be used as a gelling agent in food. Kosher gelatin may be substituted for any gelatin that does not meet kosher standards. Kosher gelatin may be derived from fish or cows rather than being derived from pig sources. In addition, kosher gelatin-like products may also be substituted. Gelatin-like products refer to substances with a similar chemical behavior which may include food starch from tapioca, chemically modified pectin, and carrageenan combined with vegetable based gums.
Embodiments of a thickening agent may be defined as any substances which increase the viscosity of a solution or liquid/solid mixture without substantially modifying its other properties. Thickening agents may be used in emulsions to improve the structural stability of the product. For example, the thickening agent may include, but is not limited to polysaccharides such as starches, gums, and pectin or proteins such as collagen, egg whites, and gelatin.
Embodiments of an emulsifying agent may be defined as substances that are soluble in both fat and water and enable fat to be uniformly dispersed in water as an emulsion, wherein an emulsion may be defined as a mixture of two or more immiscible liquids. A common example within the food industry is an oil and water emulsion. For example, the emulsifying agent may include, but is not limited to Sodium Stearol Lactylate or other fatty acid derivatives such as polyglycerol esters, propylene glycol esters, sucrose esters, sorbitan esters and polysorbates. Additionally other emulsifiers may include lechtin, honey, mustard, monoglycerides, and diglycerides.
Embodiments of a flavoring agent(s) may be a substance that gives another substance flavor, altering the characteristics of the solute, causing it to become sweet, sour, tangy, spicy, bitter, and salty or any combination thereof. The act of altering flavor of another substance may be conducted by modifying the taste or the smell of the product. For example, the flavoring agent(s) used in aerated food products may include, but are not limited to, cocoa, dark chocolate, white chocolate, strawberry, vanilla, raspberry, lemon, lime, cappuccino, coffee, peach, caramel or any other commonly known flavoring agent. Flavoring agents may come in many formulations and variations, natural or synthesized. Any known variation of cocoa, dark chocolate, white chocolate, strawberry, vanilla, raspberry, lemon, lime, cappuccino, coffee, peach, and caramel could be used when synthesizing a flavored aerated Mousse product. The resulting flavor is a matter of personal preference and any possible variation could be used. In an exemplary embodiment, the flavoring agent is De Zaan D-11-S.
Embodiments of a solution may be a homogeneous mixture composed of only one phase. In a homogeneous mixture, a solute is the substance being dissolved and the substance conducting the dissolution is known as the solvent.

In embodiments where the first food product portion is a mousse base 201, the mousse base 201 can be cooled at approximately 45-50° F. In embodiments where the second food product portion is a gelatin solution 202, the gelatin solution 202 can be cooled at approximately 90-120° F.
With continued reference to
Furthermore, embodiments of method 200 may include the step of combining the first food product portion and the second food product portion into a mixer 210, wherein the first food product portion and the second food product portion is mixed to form a mixed food product. Embodiments of the mixer 210 may share the same or substantially the same structural and functional aspects as the mixer 17 described above. For instance, from the first aseptic surge tank 203, the mouse base 201 can be metered out by a first metering device 205 to a desired proportion by controlling the flow rate from the first aseptic surge tank 203 through the means of a first pump 207, such as a rotary lobe pump, which feeds the contents of the first aseptic surge tank 203 into the mixer 210 in a controlled fashion. Embodiments of the mixer 210 may be a static mixer. At the same time, or at a time reasonably close to the transfer of the mousse base 201 from the first aseptic surge tank 203 to the static mixer 210, the gelatin solution 202 contained within the second aseptic surge tank 204 may be transferred in a controlled fashion to the mixer 210. The gelatin solution 202 may be metered out by a second metering device 215 through the use of a second pump 206, such as a progressive cavity pump, which can be user controlled to moderate a flow to the mixer 210. In an exemplary blend of the first food product portion and the second food product portion in the mixer 210 is a blend of mousse base 201 to gelatin solution 202 is in the ratio of 9:1. An exemplary temperature of the food product portions within the mixer 210 is between approximately 50-55° F. Once the mixer 210 thoroughly mixes the contents of the first and second aseptic surge tanks 203, 204, the resultant food product may be referred to as a mixed food product.
Embodiments of method 200 may further include the step of transferring the mixed food product to an aerator 211 and aerating the mixed food product to form an aerated food product. Embodiments of the aerator 211 may share the same or substantially the same structural and functional aspects of the aerator 122 described above. Embodiments of the aerator may include a Mondomix Aeration machine. The aerator 211 subsequently aerates the mixed food product received from the mixer 210 using an aerator fluid, such as nitrogen gas supplied by a micro-filtered nitrogen generator 212. The nitrogen can be supplied in a controlled fashion to the aerator 211 until the mixed food product within the aerator 211 are aerated to approximately 70% overrun. The resultant food product after achieving a target percent overrun may be referred to as the aerated food product.
