Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

This present non-provisional patent application is a continuation-in-part of copending U.S. patent application Ser. No. 12/325,201 filed on Nov. 20, 2008, and entitled “PORTABLE ELECTRIC COOLER,” and of which the application cited above is incorporated in-full by reference herein.

FIELD OF THE INVENTION

The technology described herein relates generally to electric cooling devices for food and beverages. More specifically, this technology relates to a device and methods for meat storage, tenderizing, and aging in a temperature, humidity and air flow/ventilation controlled environment, and a combined wine cooler steak ager.

BACKGROUND OF THE INVENTION

Many cooling devices are known in the art for cooling food and beverages. By way of example, cooling devices are utilized to store, age, and tenderize meat products in a temperature, humidity and air flow/ventilation controlled environment.
For many, dry aging meat, such as steaks, is a lost art. More tender and flavorful steaks and roasts can be achieved because of a method called dry aging. Typically, capability for the dry-aging of meat is available only to commercial suppliers and to top-tier restaurants. Dry-aging is expensive because of the amount of time required to age the beef and the loss of yield due to dehydration and trimming. Steaks can be dry aged by hanging uncut, just-harvested beef in a refrigerated cooler at a specific temperature and humidity for a predetermined time period, such as for example, 10 to 28 days.
The dry aging process includes exposing beef to open air for up to 28 days in an environment whose temperature, humidity and air circulation is carefully controlled. The dry aging process enhances beef by two means. First, moisture is evaporated from the muscle. This creates a greater concentration of beef flavor and taste. Second, the beef's natural enzymes break down the connective tissue in the muscle, which leads to more tender beef.

DETAILED DESCRIPTION OF THE INVENTION

Before describing the disclosed embodiments of this technology in detail, it is to be understood that the technology is not limited in its application to the details of the particular arrangement shown here since the technology described is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limitation.
In various exemplary embodiments, the technology described herein provides a device and methods for meat storage, tenderizing, and aging in a temperature and humidity controlled environment.
Referring now to the Figures, a cooler 10 is depicted. Cooler 10 is a portable, electric cooler that is suitable for home use for storing, aging, and tenderizing meats and cooling beverages such as wine. Cooler 10 includes an inner shell 12 and an outer shell 14. The inner shell 12 can be manufactured from a durable plastic material to form the inside of the refrigeration chamber for storing items such as meats for aging and wines for chilling. The inner shell 12 can be vacuum formed. The outer shell 14 can be manufactured from a durable metal. Disposed between inner shell 12 and outer shell 14 is substantial insulation foam (not shown), such as, for example, approximately up to double the amount found in conventional refrigeration devices, to help maintain the narrow temperature range required for aging meats. In one embodiment, the cooler 10 is a small portable cooler of approximately four to six cubic feet in interior storage space. This cooler size is suitable for home owners who desire aged steaks, for example, but who do not have access to expensive commercial meat coolers or top-tier restaurants having such.
Outer shell 14 includes a base 32, top 34, rear panel 30, left side panel 36, and right side panel 38. Outer shell 14 includes door frame 40 in which glass door 42 is placed. The glass door 42 is mounted to the door frame 40 such that it can swivel to either open or close as desired. The glass door 42 is tinted in at least one embodiment. A tinted glass door 42 allows visibility and monitoring within the refrigeration chamber without opening the door and disallows unwanted, unfiltered direct light contact with items stored within the refrigeration chamber. Together these components form the outer shell 14 and fully enclose the inner shell 12.
Cooler 10 utilizes a multiplicity of rack mounts 16 to provide various locations within the refrigeration chamber to place the rack 18. Meats can be hung from within the refrigeration chamber or placed on one or more of the racks 18. Cooler 10 also includes at least one circulation fan 66.
Cooler 10 utilizes a display 20 for the temperature and humidity levels measured within the refrigeration chamber. Display 20 can be an LED display. Although the temperature and humidity levels within the refrigeration chamber can be automatically and electronically adjusted as necessary, the visual display 20 enables one to instantly know the values within the refrigeration chamber.
Cooler 10 also includes a multiplicity of selection buttons 28 that enable a user of the cooler 10 to set-up, program, monitor, and otherwise adjust cooler settings, such as, but not limited to, temperature, humidity, actual time, scheduled time, etc.
Cooler 10 includes a compressor 24. The compressor 24 is configured to compress and circulate a refrigerant to cool the refrigeration chamber. When compressor 24 is running, it compresses the refrigerant in a low-pressure gaseous state to a high-pressure gas. Cooler 10 includes an expansion device 68 for expanding the refrigerant. Cooler 10 includes a condenser having high pressure coils 50.
Cooler 10 includes a first set of low pressure coils 56 disposed adjacent to the refrigeration chamber on the rear. The first set of low pressure coils 56 are fluidly coupled to the compressor 24 and configured to hold the refrigerant. Cooler 10 also includes a second set of low pressure coils disposed adjacent to the refrigeration chamber on both a left side 52 and a right side 54. The second set of low pressure coils 52, 54 are fluidly coupled to the compressor 24 and configured to hold the refrigerant. The first set of low pressure coils 56 and the second set of low pressure coils 52, 54 are alternated with refrigerant flow in order to allow one set of low pressure coils to defrost while the other set circulates the refrigerant.
The coils 52, 54, 56 are arranged in a horizontal manner and downwardly sloping. The downward slope is, for example, two degrees. This design ensures any moisture inside of the air tubes does not collect and freeze at the bottom of a bend as can happen in a vertical design.
Cooler 10 also utilizes a three-way solenoid valve 48 a. The first three-way solenoid valve 48 a is fluidly disposed after the expansion device 68 and at a beginning of each of the first set of low pressure coils and the second set of low pressure coils 52, 54 and configured to switch between the first set of low pressure coils and the second set of low pressure coils in order to allow one set of low pressure coils to defrost while the other set circulates the refrigerant and a second three-way solenoid valve 48 b. The second three-way solenoid valve 48 b is disposed at an ending of each of the first set of low pressure coils and the second set of low pressure coils and configured to combine two flows back into a single return to the compressor 24. The first set of low pressure coils and the second set of low pressure coils are maintained at the same volume in order to maintain a stable load on the compressor and to maintain a same cooling capacity.
The cooler 10 further includes a control system 44 having a timing device, among other controls, such as for temperature and humidity. The first three-way solenoid valve 48 a and the second three-way solenoid valve 48 b are configured to switch simultaneously on a predetermined time interval as controlled by the timing device.
The control system 44 also includes a temperature sensor. The refrigeration chamber is configured to be closely maintained at a temperature range immediately above freezing. The temperature is monitored by the temperature sensor and maintained in the range of 33 to 38 degrees Fahrenheit. This range is preferred for aging beef.
The control system 44 also includes a humidity sensor. The humidity is monitored by the humidity sensor and maintained in the range of 75% to 90% humidity. This range is preferred for aging beef. As will be apparent to those in the art, such sensors can be placed in varied locations within the refrigeration chamber.
The cooler 10 includes a humidity system. The humidity system provides a high level of humidity within cooler 10 to provide the preferred environment for aging beef.
The humidity system includes a water reservoir 82. The water reservoir 82 includes air ducts 84. Two fans draw the humidified air from the water reservoir 82 and circulate the humidified air throughout the cooling chamber.
The humidity system includes an air pump to supply the water reservoir 82 with a constant source of fresh air. As air is pumped into the water reservoir 82, air bubbles are created which subsequently pop upon reaching the surface of the water. The humidity system creates a higher level of humidified air to be drawn from the water reservoir 82. The humidity system allows us to maintain a constant level of humidity inside the chamber of 80-90%; the perfect level for dry aging steaks.
The humidity system also solves the problem of frost forming on the coils. Traditional systems shut off the compressor and allow the coils to melt. This increases the temperature inside the cooling chambers which would be dangerous to age steaks. The coils are defrosted without shutting off the compressor by utilizing a double set of coils that mirror the cooling coils, a first set of coils, and a second set of coils. The second set of coils is used to send the air to the water reservoir 82.
The humidity system also includes a solenoid to direct the fresh outside air being pumped in, to only travel through the side of the coils that is in the rest mode. The solenoid is for example a 3-way solenoid. Use of the solenoid is dually functional. The solenoid acts as a heat exchanger defrosting the cooled coils that are in the rest mode while pre-cooling the air that enters the water reservoir 82. This keeps the water inside the water reservoir 82 from heating up too much such that it would raise the temperature inside the cooling chamber. Another set of solenoids splits the cooling coils so that while one side shuts off to defrost, the other side continues to cool to maintain the temperature at the desired range. Dry aging steaks require constant temperature, humidity and air flow to successfully age steaks.
The cooler 10 also includes a UV-C light 62 configured to provide germicidal sterilization within the refrigeration chamber. UV-C light 62 can be located within a duct. UV-C light 62 can be located in the top of the cooling chamber. UV-C light 62 reduces the likelihood of bacterial growth on the steaks, or the like, stored in the refrigeration chamber. The cooler 10 also includes an interior light.
Disposed at a top end of duct 84 is a circulation fan 66. Circulation fan 66 provides ventilation to the refrigeration chamber. The dry aging process utilizes a means of evacuating the moist air from the dehydrating beef, to be evacuated from the unit to ensure a slow movement of fresh air around the beef. By way of example, this can be accomplished by installing a vent inside the unit or utilizing the drain for the coils for the same purpose.
In one alternative embodiment, the cooler 10 is utilized in a combination storage, aging, and tenderizing device for meats and beverage cooler for wines and the like.
In at least one embodiment, the cooler 10 can be manufactured utilizing the following general steps: vacuum form the inner shell 12, bend the copper tubing into the proper shape, join the tubing to the 3 way solenoids 48 a, 48 b, affix the copper tubing to the inner shell 12, bend the outer shell 14 out of sheet metal, place the inner shell and copper tubing inside the outer shell 14, attach the copper tubing to the compressor 24, wire all the electronics (thermostat, humidity sensor etc.) to the proper locations, fill the area between the inner and outer shells 12, 14 with insulating foam, and attached the glass door 42 with the proper mounting hardware.
Although this technology has been illustrated and described herein with reference to preferred embodiments and specific examples thereof, it will be readily apparent to those of ordinary skill in the art that other embodiments and examples can perform similar functions and/or achieve like results. All such equivalent embodiments and examples are within the spirit and scope of the invention and are intended to be covered by the following claims.
