DETAILED DESCRIPTION OF THE INVENTION

Tabletop food item steamers, methods for using them to steam food items, and methods for transferring steamed food items are described in this section.

With reference to the Figures generally, a tabletop food steaming device 10 adapted for quick steaming, removal, and transfer of food items from device 10 to a work surface is described. In particular, steaming device 10 is shown in various orientations to illustrate its structure and function, as well as a method of using the device.

As illustrated in FIGS. 1-6, steaming device 10 includes a platform support 12 which supports a food item platform 14. Food item platform 14 is illustrated separately in detail in FIG. 7. Food item platform 14 typically is essentially rectangular in shape. A steam permeable panel 16 having steaming domes 18a and 18b is attached to food item platform 14. Steam permeable panel 16 is adapted to support food items to be steamed on steaming domes 18a and 18b. Steaming domes 18a and 18b are adapted to receive a food item placed thereon. Typically, steaming domes 18a and 18b are sized to direct steam substantially uniformly onto a food item such as a bun crown or heel.

Steam permeable panel 16, shown separately in detail in FIG. 8, may be formed of any suitable steam permeable material preferably having a relatively low thermal conductivity and a relatively high temperature resistance, including but not limited to silicone, nylon or metal and may be in the form of a mesh or screen to allow steam to readily pass therethrough.

Steam permeable panel 16 may be attached to food item platform 14 in any suitable manner, including, but not limited to, the application of a thermally resistant adhesive or a mechanical fastener.

Food item platform 14 is connected to platform support 12 via a platform hinge 20. Platform hinge 20 includes at least one platform hinge attachment 22 mounted to a platform hinge bracket 24, attaching food item platform 14 to platform support 12.

Typically, platform hinge 20 allows food item platform 14 to be rotated at least 180 degrees about an essentially horizontal axis.

When food item platform 14 is substantially engaged with platform support 12 as illustrated in FIG. 1, food item platform 14 is in the food steaming position. Typically, food item platform 14 is generally horizontal when in the food steaming position. When food item platform 14 is rotated and disengaged from platform support 12 as illustrated in FIG. 4, food item platform 14 is in the food removal position. Typically, food item platform 14 can be rotated at least about 180 degrees between the food steaming position and the food removal position. Typically, the food removal position is approximately at least 135 degrees offset from the food steaming position.

Steaming device 10 further includes a cover 28. Cover 28 is shown separately in detail in FIG. 9. Cover 28 is connected to platform support 12 via a cover hinge 30. Cover hinge 30 includes at least one cover hinge attachment 32 mounted to a cover hinge bracket 34, and functions to attach cover 28 to platform support 12. When cover 28 is in the closed position, as illustrated in FIG. 2, it essentially covers food item platform 14 to form a cavity 36. Typically, cover 28 is essentially rectangular in shape and has approximately the same width and length as food item platform 14. Cover hinge 30 allows cover 28 to be opened, exposing food item platform 14. Cover hinge 30 allows the cover 28 to be rotated about an essentially horizontal axis by an operator using a cover handle 38. Cover hinge 30 allows cover 28 to be rotated at least 90 degrees about an essentially horizontal axis in the direction of arrow K. Typically, cover hinge 30 allows cover 28 to be rotated at least 135 degrees about an essentially horizontal axis, providing clearance to allow food item platform 14 to be rotated via platform hinge 20.

Cover hinge 30 typically attaches cover 28 to platform support 12 on a different side from where platform hinge 20 attaches food item platform 14 to platform support 12. Cover hinge 30 can attach cover 28 to platform support 12 in a manner to rotate in a different direction from food item platform 14. Typically, cover hinge 30 attaches cover 28 to platform support 12 in a manner to rotate in the opposite direction from food item platform 14. As illustrated in FIG. 1, food item platform 14 rotates in a counterclockwise direction, towards the left, and cover 28 rotates in a clockwise direction, towards the right.

Optionally, platform hinge attachments 22 and cover hinge attachments 32 are adapted to be selectively mounted to either platform hinge bracket 24 or cover hinge bracket 34, interchangeable between the hinge brackets. Preferably, platform hinge attachment 22 can be connected to either platform hinge bracket 24 or cover hinge bracket 34 and cover hinge attachment 32 can be mounted to either platform hinge bracket 24 or cover hinge bracket 34. Food item platform 14 is situated in either a leftward pivoting or rightward pivoting orientation, allowing food item platform 14 to be rotated in either the clockwise or counterclockwise direction depending on the preferred mode of operation, and accommodating both right-handed and left-handed human operators. Cover 28 is situated in either a leftward pivoting or rightward pivoting orientation, allowing cover 28 to be rotated in either the clockwise or counterclockwise direction depending on the preferred mode of operation.

Cover 28 includes alternate handle mounts 42a and 42b at adjacent corners to allow cover handle 38 to be attached at the appropriate corner to be accessible from the front of steaming device 10 in its leftward pivoting or rightward pivoting orientations. As illustrated in FIG. 7, food item platform 14 further includes similar alternate handle mounts 40a and 40b at adjacent corners to allow platform handle 26 to be attached at the appropriate corner to be accessible from the front of steaming device 10 in its leftward pivoting or rightward pivoting orientations. FIG. 6 is an illustration of platform support 12 with food item platform 14 and cover 28 detached therefrom, ready for each of food item platform 14 and cover 28 to be mounted to either hinge bracket 24 or hinge bracket 34 as desired.

Steaming device 10 also includes a button 44 for activating steaming device 10. Steaming device 10 also includes an LED indicator 46 which indicates when the steaming process is complete. The steaming device may also include any other type of suitable indicator that steaming is complete, including, but not limited to, an audible signal.

FIG. 2 illustrates steaming device 10 in the closed position. Cover 28 is pivotally rotated to engage with platform support 12, forming cavity 36. Preferably, cover 28 cooperatively engages with platform support 12 to form steaming cavity 36 when steaming device 10 is in the closed position, to at least substantially retain steam inside cavity 36 during steaming. Steaming is initiated by an operator by activating button 44 or triggering any other appropriate actuator. A controlled quantity of steam is injected through steam permeable panel 16 once steaming is initiated. Typically, a food item is located on steaming domes 18a and 18b and is steamed from the controlled quantity of steam. The food item can be any food item that is to be steamed. Typically the food item is a bun piece, such as a bun heel H or a bun crown C.

As illustrated in FIG. 7, to permit passage of steam from a steam source into heel H and crown C, food item platform 14 includes platform openings 48a and 48b, which communicate with steaming domes 18a and 18b, respectively. Platform support 12 includes steam outlets 50a and 50b, as illustrated in FIG. 4, which communicate with steaming domes 18a and 18b, respectively.

Any suitable steam source may be configured in communication with steam outlets 50a and 50b to provide controlled quantities of steam for injection into food items in steaming device 10. Each steam outlet may have its own steam source or may share a common steam source. Referencing schematic FIG. 2a, a common steam source 52 supplies steam to both steam outlets 50a and 50b, via respective heated sinks 54a and 54b. A microprocessor control system 56 is provided for directing solenoids 58a and 58b to provide a water pulse to one of associated heated sinks 54a and 54b about 0.1 second before providing a water pulse to the other heated sink. Such staggering of water pulses has been found to promote more uniform water input to each heated sink than simultaneous water pulses and consequently, a more uniform quantity or shot of steam from heated sinks 54a and 54b.

As illustrated in FIG. 3, steaming device 10 includes platform support 12, food item platform 14, and cover 28. Cover 28 is in an open position, and clamshell box B is in place over the steamed food item to be transferred to a work surface 60 together with the steamed food item. Any appropriate packaging may be placed over the steamed food item. Typically, the packaging is a clamshell box. Placing packaging over the steamed food item prior to transferring the food item to a work surface is advantageous when it is desired to prevent the food item from directly contacting the work surface or the hand of a human operator. The work surface can be any appropriate surface for holding or preparing the food item. Typically the work surface is an approximately horizontal surface or table.

As illustrated in FIG. 4, steaming device 10 includes platform support 12, food item platform 14, steaming domes 18a and 18b, steam outlets 50a and 50b, and cover 28. Cover 28 is in the open position. Food item platform 14 is shown in an open position. Clamshell box B is on work surface 60, transferred to work surface 60 from the rotational momentum to the steamed food items and clamshell box B during rotation of food item platform 14 from the food steaming position to the food removal position. Clamshell box B contains bun heel H and crown C with cut faces F facing upward as illustrated in FIGS. 4-5 to facilitate placement of sandwich ingredients on cut faces F.

FIG. 5 illustrates steaming device 10 in the food steaming position, after steamed buns have been transferred to work surface 60. Steaming device 10 can now receive another food item to be steamed.

FIG. 8 illustrates steam permeable panel 16. Steam permeable panel 16 includes steaming domes 18a and 18b. Steaming domes 18a and 18b are of the appropriate size and shape to accept placement of a food item thereon. Typically, steaming domes 18a and 18b are slightly larger than a hamburger bun and accept placement of a hamburger bun thereon.

FIG. 9 illustrates cover 28. Cover 28 is dome shaped to form a cavity when cover 28 is in the closed position and engaged with a food item platform. Cover 28 is typically a curved dome. The curved dome prevents water from falling from the cover back onto the steamed food item. This improves the quality of the food item and prevents the food item from getting soggy. This is especially important for a bun or other bread product which could easily become soggy and of a decreased quality if water were permitted to drip thereon. Cover 28 further includes cover hinge attachments 32 to allow cover 28 to be attached to a platform support on a steaming device. Cover 28 includes alternate handle mounts 42a and 42b at adjacent corners to allow a cover handle to be attached at the appropriate corner to be accessible from the front of a steaming device in its leftward pivoting or rightward pivoting orientations.

In another embodiment, as generally illustrated in FIGS. 24-25, food steaming device 180 is provided. Food steaming device 180 includes a platform support 182 which supports a food item platform 184. Platform support 182 can be of a desired shape and as shown is rectangular in shape and rests on a work surface 186. Platform support 182 can completely rest on work surface 186 without any portion of the device overhanging work surface 186. Food item platform 184 is typically rectangular or generally rectangular in shape, but can be any suitable shape as desired. Food item platform 184 includes a food item support riser 188. Platform support 182 includes platform hinge 190 and cover hinge 192.

Steaming device 180 further includes a cover 194. Cover 194 is connected to platform support 182 via a cover hinge 192. When cover 194 is in the closed position, it essentially covers food item platform 184 to form a cavity. Typically, cover 194 is essentially rectangular in shape and has approximately the same width and length as food item platform 184. Cover hinge 192 allows the cover 194 to be rotated about an essentially horizontal axis by an operator using a cover handle 196. Cover hinge 192 allows cover 194 to be rotated at least 90 degrees about an essentially horizontal axis in the direction of arrow R. Typically, cover hinge 192 allows cover 194 to be rotated at least 135 degrees about an essentially horizontal axis, providing clearance to allow food item platform 184 to be rotated via platform hinge 190. Platform hinge 190 and cover hinge 192 can be on the same side of food item platform 184 as illustrated in FIG. 25. Alternatively, platform hinge 190 and cover hinge 192 can be on opposite sides of food item platform 184 as illustrated in FIG. 24.

Platform support 182 includes steam outlets 198a and 198b. Steam outlets 198a and 198b include bun supports 200a and 200b. Bun supports 200a and 200b each include three support arms 202a-f, respectively. Bun support 200a includes three support arms 202a-c and bun support 200b includes three support arms 202d-f. Support arms 202a-c and 202d-f are about equally spaced radii in the form of a circular pattern in about the same size as steam outlets 198a and 198b. Steam outlets 198a and 198b also include a plurality of peripheral steam openings 204a and 204b. Peripheral openings 204a and 204b are located between steam outlets 198a, 198b and bun supports 200a, 200b. Peripheral openings 204a, 204b allow steam to pass through peripheral openings 204a, 204b and enter the cavity defined by cover 194 when rotated in the closed position to engage cover 194 with platform support 182. Steam can pass through the peripheral openings 204a, 204b to make a bun crown surface shiny while steaming the underside of the bun. Typically, it is intended for a bun crown or heel to be located on bun support 200a or 200b interiorly of peripheral openings 204a or 204b and the components of platform support 182 are appropriately sized to this end.

In an additional embodiment of the present invention, it is possible to place multiple steaming devices end to end, linearly arranged on a workspace. Such an arrangement would allow for multiple steaming devices to be contained within one housing. Each steaming device typically would contain its own set of controls, which could operate each of the steaming devices individually or together as a unit. Typically, two steaming devices would be placed end to end, linearly arranged on a workspace such as a counter, and contained within one housing. A user could access the steaming devices from either side of the workspace, allowing for operation of the steaming devices from either side of the workspace.

In another embodiment of the present invention, a method of producing a steamed food item is provided. A food steaming device of one of the types in accordance with the invention as previously described is provided. For example, the food steaming device includes a food item platform; a platform support; a platform hinge connecting the food item platform to the platform support, wherein the food item platform is pivotable between a food steaming position and a food removal position; a food item support riser connected to the food item platform; and a steam source communicating with a steam outlet, the steam outlet configured to direct steam onto the food item platform when the food item platform is in the food steaming position.

The food item platform is placed in the food steaming position. When in the food steaming position, the food item platform is substantially engaged with a platform support. An example of a food item platform in the food steaming position is illustrated in FIG. 15. Typically, the food item platform is generally horizontal when in the food steaming position.

A food item desired to be steamed is placed on the food item support riser. Any appropriate food item can be steamed. Typically, tortillas to be steamed are placed on the food item platform, overlaying, for example, both steaming domes 138a and 138b on steam outlets 198a and 198b, the tortilla also being supported by support riser 135, such as shown, for example, in FIGS. 15 and 16.

Steam is directed through the steam outlet and onto the food item for a period of time sufficient to essentially steam the food item. The time period sufficient to essentially steam the food item depends on the food item. For a typical tortilla or bread product, the period of time sufficient to essentially steam the tortilla or bread product is approximately 12 seconds. Any suitable steam source may be configured in communication with the steam outlets to provide controlled quantities of steam for injection into food items. For multiple steam outlets, each steam outlet may have its own steam source or may share a common steam source. Referencing schematic FIG. 2a, a common steam source 52 supplies steam to both steam outlets 50a and 50b, via respective heated sinks 54a and 54b. Steam outlets 50a and 50b are approximately circular in shape. Steam outlets may be any appropriate shape, such as oval or circular. Typically, the steam outlets are circular. A microprocessor control system 56 is provided for directing solenoids 58a and 58b to provide a water pulse to one of associated heated sinks 54a and 54b about 0.1 second before providing a water pulse to the other heated sink. Such staggering of water pulses has been found to promote more uniform water input to each heated sink than simultaneous water pulses.

When the food item is substantially steamed, or steamed a desired amount, the food item is removed from the food item support riser. Any appropriate apparatus to remove the food item may be used. Typically, tongs are used to remove the food item from the food item support riser.

In a further embodiment of the invention, apparatus is provided to send a signal when the food item is essentially steamed. The signal can be any appropriate signal, including, but not limited to, a visual signal, which may be an LED indicator. Alternatively, or in addition to the visual signal, an audible signal can also be utilized.

In another embodiment of the method aspects of the invention, a cover is provided. The cover is movable between an open position and a closed position on the platform support. Typically the cover is moved to the open position to permit placing a food item on the food item support riser. The cover is moved to the closed position, defining a cavity. The cavity typically comprises the food item and is configured to at least substantially retain steam. The cover engages with the platform support to provide a seal between the cover and the platform support, allowing the food to be steamed within the cavity. After steam is directed from the steam source through the food item, the cover is moved to the open position to permit the food item to be removed from the food item support riser.

While the invention has been described with respect to certain preferred embodiments, as will be appreciated by those skilled in the art, it is to be understood that the invention is capable of numerous changes, modifications and rearrangements, and such changes, modifications and rearrangements are intended to be covered by the following claims.
