The present invention relates to food processing devices and related methods. More specifically, the present invention disclosure relates to devices and methods for peeling an outer layer of a foodstuff such as, without limitation, garlic cloves.
Certain foodstuffs require processing prior to being cooked. For example, and without limitation, garlic cloves have a skin that must be removed from a garlic core prior to using the garlic core in a cooking dish. Removal of such skins may be accomplished manually or using a traditional cooking utensil, e.g., a knife, or semi-automatically using a food peeling device.
Food peeling devices for peeling garlic include cylindrical tubes fabricated from rubber materials. A user can peel a garlic clove by placing the garlic cloves into the rubber tube, squeezing the tube to compress the garlic, and rolling the tube along a hard surface to loosen and remove the garlic skin.
Existing food peeling devices do not lend themselves to high-volume processing. More particularly, loading and unloading garlic cloves from the rubber tubes described above, or removing spent skins from the rubber tube, can be time consuming. In addition, existing food peeling devices generally require the use of both hands, which does not allow other concurrent activities using the other hand, and which make such devices difficult to use by those with physical hand or finger impairments. Accordingly, a food peeler that is easy to load, unload, use and clean would be advantageous to a user by making food preparation easier, e.g., by reducing the time required to perform and/or clean up after a food preparation process or to clean up afterward, and by requiring only one hand to operate.
The present invention provides methods and apparatus for quickly and efficiently removing peels or skins from foodstuffs. Embodiments of the invention include a base member suitable for use on a flat surface, and a second movable member that engages with the base member. The base member has an upper frictional surface that is provided in an elongated gap between two upwardly extending parallel sidewalls, the gap being open at both ends. The movable member includes a protruding section that is designed and sized to fit between the parallel sidewalls of the base member, and includes a lower frictional surface. The movable member may be engaged with the base member such that the frictional surfaces on the base member and movable member oppose each other, and either come close to or make contact with each other. In embodiments of the invention, the open ends of the gap allow the movable member to be slidably moved back and forth along the gap between the sidewalls of the base member, moving the frictional surfaces against each other.
In some embodiments, the frictional surfaces on the base and on the movable member may be the same or may be made of the same material, whereas in other embodiments these surfaces may be different or made of different materials. For example and without limitation, in some embodiments, different patterns of raised or rough areas may be provided on either or both of the frictional surfaces of the base and movable member. In some embodiments, only one of the apposing surfaces (either the base or movable member) is frictional. In some embodiments, rubber or rubber like materials may be provided on one or both of the base and/or movable member to provide the apposing frictional surfaces for these members. Suitable materials for the frictional surfaces include without limitation, rubber, latex, silicone, and the like. In other embodiments, the apposing surfaces on the base and/or movable member may be coated with resins or other materials that may partially or completely harden to provide rough frictional surfaces. For example, the frictional surfaces can be rough surfaces.
In some embodiments, the base member may be provided with one or more lower panels or lips that extend out from the base. These panels or lips provide stability to the base member while also providing a place where a user may hold the base in place while moving the movable second member back and forth. In some embodiments, a handle, grip or other similar structure may be provided on the base that may be engaged by a user to steady the base while the embodiment is in use. In other embodiments, a suction may be provided to temporarily adhere the base to a surface, such as a counter or table top. In other embodiments, a rubberized band may extend completely around the base member providing an upper frictional surface that opposes the movable member, and a lower frictional surface which prevents slippage of the base on a counter or table top.
In use, the base of an embodiment of the invention is provided on a flat surface such as a counter or table top, with an optional panel extending from the base toward the user. The user may place a hand or elbow on the panel to steady the base, or the panel may be engaged with or clamped to the table top. The user holds the movable second member in the other hand. Unpeeled foodstuffs (e.g., cloves of garlic, pinion nuts, pine nuts) may be placed on the frictional surface of the base between the parallel sidewalls of the particular embodiment. For some foodstuffs such as pine nuts and the like, the nuts may first be impacted or stricken with the user's palm or some other convenient utensil to create a break in the outer skin of the foodstuff before placing it in the base. After the unpeeled foodstuffs are placed on the base, in some embodiments, the second movable member is inserted into the gap, pressed against the foodstuffs, and moved back and forth. This causes the foodstuffs to be trapped under pressure between the upper surface of the base and the lower surface of the movable member, where either or both of the surfaces are frictional. The oscillating motion of the second member in the gap causes the foodstuffs to roll between the frictional surfaces of the base and the movable member, having the effect of removing the peels, skins or outer layers therefrom. Once these outer layers have been removed, the second movable member is taken away, exposing the peeled foodstuffs and the removed peels. The peels may ordinarily be removed from the base by rinsing the base under a stream of water or by gently blowing the peels away, leaving the peeled foodstuffs available for use.
The above summary does not include an exhaustive list of all aspects of the present invention. It is contemplated that the invention includes all devices, systems, and methods that can be practiced from all suitable combinations of the various aspects summarized above, as well as those disclosed in the Detailed Description below and particularly pointed out in the claims filed with the application. Such combinations have particular advantages not specifically recited in the above summary.
It is therefore an object of the invention to provide methods and apparatus for quickly and easily removing the outer layers of foodstuffs.
It is a further object of the invention to provide methods and apparatus for removing the outer layers of foodstuffs that is easy and simple to clean and store between uses.
It is a further object of the invention to provide methods and apparatus for removing the outer layers of foodstuffs without damaging the foodstuff from which the outer layer has been removed.
It is a further object of the invention to provide methods and apparatus for removing the outer layers of foodstuffs that are easy to operate using only one hand and by physically impaired persons.
Additional objects of the invention will be apparent from the detailed descriptions and the claims herein.
The novel features of the invention are set forth with particularity in the claims that follow. A better understanding of the features and advantages of the present invention will be obtained by reference to the following detailed description that sets forth illustrative embodiments, in which the principles of the invention are utilized, and the accompanying drawings of which:
Embodiments describe a food peeler and methods for peeling or removing an outer layer of a foodstuff, e.g., shells, peels, skin of a garlic clove, outer layers of pine nuts or pinion nuts, etc. Although certain embodiments are described below with specific mention of peeling garlic cloves, it will be appreciated that the food peeler may be used in other applications, such as removing shells from peanuts or pine nuts. Accordingly, the scope of the claims below are not limited solely to a garlic peeler or a method of peeling garlic.
In various embodiments, description is made with reference to the figures. However, certain embodiments may be practiced without one or more of these specific details, or in combination with other known methods and configurations. In the following description, numerous specific details are set forth, such as specific configurations, dimensions, and processes, in order to provide a thorough understanding of the embodiments. In other instances, well-known processes and manufacturing techniques have not been described in particular detail in order to not unnecessarily obscure the description. Reference throughout this specification to “one embodiment,” “an embodiment,” or the like, means that a particular feature, structure, configuration, or characteristic described is included in at least one embodiment. Thus, the appearance of the phrase “one embodiment,” “an embodiment,” or the like, in various places throughout this specification are not necessarily referring to the same embodiment. Furthermore, the particular features, structures, configurations, or characteristics may be combined in any suitable manner in one or more embodiments.
The use of relative terms throughout the description may denote a relative position or direction. For example, “forward” may indicate a first direction along a longitudinal axis of a food peeler. Similarly, “proximal” may indicate a second direction opposite to the first direction. Such terms are provided to establish relative frames of reference, however, and are not intended to limit the food peeler to a specific configuration described in the various embodiments below.
In an aspect, a food peeler has several members that move relative to each other, and more particularly, apposing surfaces of the members can move in a longitudinal direction relative to each other. One or more of the apposing surfaces can have a texture to increase friction between the textured surface and a foodstuff, e.g., a garlic clove, that is being peeled. For example, the texture can be a frictional surface, such as a rough surface. Accordingly, the foodstuff can be rolled between the apposing surfaces to cause an outer layer, e.g., a skin, of the foodstuff to loosen and/or remove from a core of the foodstuff.
Referring to
The members of the food peeler can be operatively coupled to each other. For example, in addition to being capable of moving relative to each other in the longitudinal direction, relative movement between the members may be limited in one or more other directions. In an embodiment, one or more of the members have a constraint to limit movement of the members in a predetermined direction. For example, the second member can have a constraint 112 to limit movement of the first member relative to the second member in a transverse direction 114 when the second member is mounted on the first member. By contrast, the constraint 112 can allow movement of the first member relative to the second member in another direction, e.g., in a longitudinal direction to allow longitudinal movement between the members. In an embodiment, the transverse constraint can include surfaces of the members, e.g., a first lateral surface 116 of the first member and a second lateral surface 118 of the second member, that act as stops against each other to limit transverse movement. In other embodiments, mechanisms such as bearings, tracks, bands, or other constraints may be used to allow limited relative movement between the members of the food peeler.
One or more of the inner surfaces of the members can have a rough texture. For example, the first inner surface can have a first rough texture 120. A structure of the rough texture is described in more detail with respect to certain embodiments in

The wall portion can have a rectangular footprint and a thickness between a bottom surface 306 and a top surface 308. It is noted here that a “top” and “bottom” surface has been used to describe thicknesses of both the base portion of the first member and the wall portion of the second member. Such terminology, however, does not limit the use of the food peeler to a particular orientation. For example, it will be appreciated by comparison of
One or more constraints 112 can extend upward from the wall portion. For example, the constraints 112 can be upwardly extending walls. The upwardly extending walls can be parallel sidewalls having lateral surfaces. More particularly, the constraints can include the second lateral surfaces 118, as described above. In an embodiment, the bottom surface 306 can be roughened, e.g., knurled, to increase friction between the wall portion and an external surface, e.g., a table or a hand of a user.
Referring to
When the members are mounted on each other, e.g., when the rack portion is cradled within and laterally between the constraints, the first member can move freely relative to the second member. More particularly, the members can move freely in at least one direction, e.g., the longitudinal direction. As described above, movement of the members can be limited in at least one direction, e.g., the transverse direction. In an embodiment, movement can be constrained in several directions. For example, the food peeler can include a stop (not shown). The stop can limit movement of the first member relative to the second member, e.g., in the longitudinal direction. The stop could be a band that is connected to the first member at a first end and to the second member at a second end. Accordingly, movement of the members can be limited by a length of the band. More particularly, when the members move sufficiently to place the band in tension, further movement in the longitudinal direction may be impeded by the stop.

Similarly, in the embodiments shown in
It is to be appreciated that surfaces 120 and 304 do not necessarily require protrusions or patters having substantial or even significant relief in comparison to surfaces 106 and 108. For example and without limitation, a simple nearly smooth rubberized material may be used for one or both of surfaces 120 and 304. Such a rubberized material will ordinarily provide sufficient friction to engage the outer layer of the foodstuff to be peeled causing such outer layer to be removed when sandwiched between one or two moving layers of such material. Of course, in other embodiments, if additional friction is desired for different foodstuffs, any suitable pattern of protrusions may be provided on one or both of surfaces 120 and 304 to engage the outer layer(s) of such foodstuffs for removal.
Advantageously, the food peeler described above can be easily loaded and unloaded. For example, a user may separate the members in the vertical direction (orthogonal to the longitudinal and transverse directions) to expose the rack portion and/or the channel between the constraints. A foodstuff can be placed into the channel or on the rack and the members may be mounted on each other to sandwich the foodstuff for peeling. After moving the members longitudinally to roll the foodstuff and peel the skin, the members may again be separated to lift the peeled core out of the channel for use in cooking. While separated, the members can be placed under running water or submersed in water to wash away the spent skins and clean the textured surfaces. In other embodiments, blowing air onto the separated members may be sufficient to dislodge and remove any waste or spent skins removed from the foodstuffs. The process can be repeated quickly and easily to increase food processing throughput compared to existing food peeling devices.
In the foregoing specification, the invention has been described with reference to specific exemplary embodiments thereof. It will be evident that various modifications may be made thereto without departing from the broader spirit and scope of the invention as set forth in the following claims. The specification and drawings are, accordingly, to be regarded in an illustrative sense rather than a restrictive sense.
