In another aspect, the concrete countertop may additionally, or alternatively, include a heating element embedded within the concrete slab to facilitate maintaining the work surface at an elevated temperature. The concrete countertop may further include a control communicating with the refrigeration motor and/or the heating element and operative to maintain the work surface within a desired temperature range.
Description
- The present invention relates generally to countertop structures, and more particularly to a temperature controlled concrete countertop.
- Concrete has long been used as a structural building material for forming building elements such as walls and floors. Recently, concrete has been used to form countertop surfaces, providing an alternative to other surface materials, which may be natural materials, such as granite or marble, or resinous man-made materials, such as Corian®. In certain applications, it may be desirable to prepare foodstuffs on a countertop surface. When foodstuffs will be in direct contact with the countertop surface, the surface must be prepared such that it is suitable for contact with the food.
- In the preparation of certain foodstuffs such as pastries, chocolates, or other confectionary items, it is desirable to maintain the foodstuff at a reduced temperature so that the foodstuff may be more easily prepared and handled. For example, chocolate confections that are prepared at reduced temperatures more readily hold a set shape, thereby facilitating the formation of decorative designs as may be desired. In other applications, it may be desirable to maintain foodstuffs at elevated temperatures during preparation.
- Various devices have been proposed for cooling a surface for the display of foods. These prior devices have generally located cooling components beneath a surface, such as a marble block, or sandwiched the cooling components between two different materials. The cooling characteristics of these devices are less than desirable, due to the different thermal properties of the different materials used in their construction. Moreover, none of these devices are configured to permit the preparation of foodstuffs directly on a concrete surface that is suitable for use as a countertop in residential or commercial kitchens.
- A need therefore exists for a device that facilitates preparing foodstuffs under controlled temperature conditions and overcomes drawbacks of the prior art, such has those discussed above.
- The present invention provides a concrete countertop with a work surface that is suitable for direct contact with foodstuffs and which can be controlled to maintain a desired temperature. In one embodiment, the countertop includes a concrete slab that has an embedded piping circuit. Refrigerant disposed within the piping circuit is circulated though the piping circuit by a refrigeration motor coupled to ends of the piping circuit. Accordingly, the concrete slab and work surface are cooled by the circulation of refrigerant through the piping circuit.
- The concrete slab may be supported on a base, which may be in the form of a cabinet with wheels to facilitate moving the countertop, or in the form of a portable enclosure that can be placed on an existing counter structure. The concrete slab may be formed in any desired size or configuration needed. For example, a 24-inch square slab may be suitable for a portable concrete countertop. Larger slab sizes, such as 36-inches by 72-inches, or even larger, may be desired for more permanent countertop structures such as those built into commercial or residential kitchens.
- In one aspect of the invention, the work surface has a highly polished finish obtained by polishing the concrete slab with a finishing tool of at least 3500 grit size. The work surface of the concrete slab is treated for direct contact with foodstuffs by a penetrating primer and a sealant applied to the work surface. The primer and sealant are safe for direct contact with food.
- In another aspect of the invention, the concrete countertop includes a control for maintaining the work surface within the desired temperature range. The control may include a display, which could indicate a current or desired temperature of the work surface, and an input device to permit users to set a desired temperature of the work surface. The countertop may additionally, or alternatively, include a heating element embedded within the concrete slab to facilitate maintaining the work surface at an elevated temperature.
- The features of the present invention will become more readily apparent from the following Detailed Description taken in conjunction with the accompanying drawings.
- The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with a general description of the invention given above, and the detailed description given below, serve to explain the invention.
-
FIG. 1 is a cross-sectional view depicting one embodiment of a countertop according to the present invention; -
FIG. 2 is a cross-sectional view depicting another embodiment of a countertop according to the present invention; and -
FIGS. 3-5 are perspective views depicting a method for creating a concrete countertop according to the present invention. -
FIG. 1 depicts anexemplary concrete countertop 10 of the present invention, in cross-section. Thecountertop 10 includes aconcrete slab 12 which has been treated and finished such that awork surface 14 of theslab 12 is suitable for direct contact with foodstuffs so that foodstuffs may be safely prepared directly thereon. Embedded within theconcrete slab 12 is apiping circuit 16, which may be a continuous length ofconduit 18 having first andsecond ends conduit 18 may be shaped and arranged to facilitate cooling theconcrete slab 12 and thework surface 14. For example, theconduit 18 may be bent to have a series of alternating turns at the ends of spaced, parallel straight sections of conduit, as best depicted inFIG. 3 . It will be recognized that the conduit may be formed in various other manners, as desired, to create a passage through which a refrigerant may be circulated to facilitate cooling theconcrete slab 10. - In the embodiment shown, an
optional metal plate 19 is coupled to thepiping circuit 16 to facilitate heat transfer between thepiping circuit 16 and theconcrete slab 12. Theplate 19 may simply be in contact with thepiping circuit 16, or it may be connected thereto, such as by welding, brazing, using mechanical fasteners, or by other methods. In this embodiment, theplate 19 is contiguous with the expanse of thepiping circuit 16 in the concrete slab, and thereby covers an area that extends at least to the distal edges of thepiping circuit 16. It will be recognized, however, that theplate 19 may alternatively cover and area that is greater or smaller than the area covered by thepiping circuit 16. - With continued reference to the drawings, the first and
second ends conduit 18 are coupled, respectively, to inlet andoutlet ports refrigeration motor 28 byfittings 25, such as quick-disconnect fittings, for example. Therefrigeration motor 28 is coupled to anexterior power source 27 by apower cord 31 extending therefrom. In one embodiment, theexterior power source 27 may be a conventional 110 volt or 220 volt outlet. Therefrigeration motor 28 will generally include a compressor and a refrigerant expansion device (not shown) whereby refrigerant that is contained within thepiping circuit 16 may be circulated through thepiping circuit 16 by therefrigeration motor 28 to thereby cool theconcrete slab 12 and thework surface 14 of thecountertop 10. Advantageously, the cooledwork surface 14 facilitates the preparation of various foodstuffs directly thereon while maintaining the foodstuff at a reduced temperature. - The
countertop 10 may further include a base or housing structure 30 to support theconcrete slab 12. Advantageously, the base 30 may support the concrete slab 12 a distance above a floor surface so that thework surface 14 is conveniently positioned for handling and preparing foodstuffs. In the embodiment depicted inFIG. 1 , the base 30 is formed from a series of vertical andhorizontal framing members vertical framing members more shelves 36 to support components of thecountertop 10, such as therefrigeration motor 28, or to provide convenient storage areas beneath theslab 12. In the embodiment shown,concrete slab 12 is supported on a top panel orshelf 38 at an upper end of the base 30. The lower edges of theslab 12, adjacent thetop shelf 38 may be fitted withdecorative trim 40. The base 30 may further include wheels orcasters 42 provided at a lower end thereof to facilitate moving thecountertop 10 as may be desired. Accordingly, thecountertop 10 may be provided as a fixed installation or as a mobile or portable unit. -
FIG. 2 is a cross-sectional view depicting another embodiment of acountertop 10 a according to the present invention, wherein thecountertop 10 a is a portable unit that may be carried and placed upon an existing counter structure. Features ofcountertop 10 a, which are similar to features shown and described with respect tocountertop 10, are similarly numbered. In this embodiment, the base 30 a includes a relatively smaller housing structure which encloses therefrigeration motor 28. The base 30 may be fitted withfeet 44 at a lower portion thereof to facilitate locating the portable unit on the existing structure without scuffing or marring the structure. - With continued reference to
FIG. 1 , thecountertop 10 may further include acontrol 50 in communication with therefrigeration motor 28 and operative to maintain the temperature of thework surface 14 of theconcrete slab 12 within a desired temperature range. In the embodiment shown, thecontrol 50 includes adisplay 52 for providing a visual indication of the temperature of thework surface 14, and a selector orinput device 54, such as a dial, to permit users to set a desired temperature for thework surface 14. Thecontrol 50 will operate therefrigeration motor 28, (for example, by turning the motor on and off) to circulate refrigerant through thepiping circuit 16 so that the desired temperature of theconcrete slab 12 is attained and maintained. In one embodiment, thecontrol 50 is operative to maintain the temperature of theconcrete slab 12 within a range of approximately 40° F. to 80° F. - The
concrete slab 12 of thecountertop 10 is formed from a mixture of Portland cement, sand, water, and other additives such as structural fibers (e.g. glass fibers) and plasticizers to provide strength and durability to the slab. The concrete mixture may further include a liquid admixture that is formulated to stop moisture vapor migration, prevent alkali efflorescence attack and corrosion of embedded metal components. One such admixture is Moxie 1800 Super-Admix, available from Moxie International, Sacramento, Calif. An exemplary plastisizer that may be used is Melment® F10, available from SKW Chemicals, Inc., Marietta, Ga. Various pigments may also be added to the concrete mixture to color the concrete, as may be desired. Concrete pigments in various colors are available from Davis Colors Company, Beltsville, Md. In one embodiment, the slab is about 1½ to 2 inches thick. Theslab 12 may be formed in any size and shape, as desired. For example, a slab which has a work surface within an envelope of not more than 24 inches wide and 24 inches deep, or 36 inches wide and 36 inches deep, may be desirable for a portable or relocateable countertop. Larger work surfaces 14, such as about 72 inches wide and about 36 inches deep, or even larger, may be suitable for countertops which are intended for more permanent installations, such as in commercial or residential kitchens. In addition, it will be recognized that theconcrete slab 12 may be formed in custom shapes and various other configurations, as may be desired. - Referring now to
FIGS. 3-5 , one method of making aconcrete countertop piping circuit 16 within theconcrete slab 12, a formingframe 60 havingside walls concrete slab 12 is partially filled with afirst layer 70 of wet concrete. According to this method, theconcrete slab 12 is formed “upside down” in the forming frame, such that thework surface 14 will be formed at a lower,first side 72 of theframe 60 and the bottom 74 of theconcrete slab 12 will be formed at an open, upper,second side 76 of theframe 60. Thefirst layer 70 is smoothed to evenly distribute the wet concrete within theform 60. - Before the
first layer 70 cures, thepiping circuit 16 is placed on thefirst layer 70 as depicted inFIG. 4 . To ensure that thepiping circuit 16 is located a desired distance from thework surface 14, thepiping circuit 16 may be supported bytabs 78 or other structure extending outwardly from thepiping circuit 16 to engage the top edges of theform 60. Thepiping circuit 16 is configured such that the first and second ends 20, 22 of theconduit 18 extend beyond theform 60, such as beyond the open,second end 76, so that the first and second ends 20, 22 of theconduit 18 will protrude from the formedconcrete slab 12, as depicted inFIG. 5 . While the first and second ends 20, 22 of theconduit 18 are shown and described herein to extend from the bottom 74 of theconcrete slab 12, it will be recognized that theconduit 18 may alternatively extend from other portions of the concrete slab. - A second layer 80 of wet concrete is thereafter poured atop the
first layer 70 and thepiping circuit 16 so that the first andsecond layers 70, 80 of concrete coalesce to form a unitaryconcrete slab 12 with thepiping circuit 16 embedded therein. The bottom surface 74 may then be smoothed with a trowel to create a substantially flat surface. - After the
concrete slab 12 has sufficiently cured, theslab 12 is removed from theform 60 and the side defining thework surface 14 is ground and polished to a smooth, highly polished finish. In an exemplary embodiment, thework surface 14 is wet sanded with a 3500-grit diamond sanding pad to create this highly polished finish. In another embodiment, the surface roughness of thework surface 14 after finishing is between about two to four microinches. After thework surface 14 has been ground and polished, thework surface 14 is treated with aprimer 82 andsealant work surface 14, as depicted inFIGS. 1 and 2 . In an exemplary embodiment, thework surface 14 is treated with two coats of a penetrating primer such as Primer 100, and two coats of a sealant such as Polyurethane 200 or Polyurethane 250 sealant, each available from Arizona Polymer Flooring, Inc. in Glendale, Ariz. In another embodiment, the total thickness of the sealant layer(s) 84, 86 applied to thework surface 14 is approximately 6 to 8 mils. Because thework surface 14 will come into direct contact with foodstuffs, theprimer 82 andsealant work surface 14 has been sealed, refrigerant may be placed in thepiping circuit 16 and thepiping circuit 16 coupled to arefrigeration motor 28 to form thecountertop - The following Examples illustrate exemplary concrete formulations useful for practicing the invention.
