The present disclosure is related generally to devices for shelling nuts.
Nuts, such as peanuts, are a popular snack and for some a staple product in view of the high protein, vitamin, and antioxidant content of the nuts. Obtaining out-of-shell peanuts may be difficult for underdeveloped or geographic regions that are still developing and have limited manufacturing resources. Additionally, some consumers who readily have access to out-of-shell peanuts simply prefer the taste, condition, and/or purchase price of nuts that are in-shell rather than out-of-shell or pre-shelled nuts.
Whether consuming in-shell peanuts because of preference or because of availability, personal consumption of in-shell peanuts may require individually splitting the nuts by hand, a process that may be painful, tedious, and messy.

As depicted in the embodiment illustrated in
The actuating cap 130 is generally rotatably coupled to the crown 114 of the cylindrical housing 110. As demonstrated, the actuating cap 130 may include a hub 131 configured to surround an outer portion of the cylindrical housing 110. Hub 131 helps maintain concentric rotation of actuating cap 130 about the cylindrical housing as the actuating cap is rotated coaxially with the drum 120. As noted herein, actuating cap 130 includes an opening 134 of a coupling socket 133. Coupling socket 133 and opening 134 facilitate fixably coupling the actuating cap 130 to the drum 120. As such, when actuating cap 130 is rotated, for example via a user turning the actuating cap by hand, the drum 120 is rotated within the cylindrical housing 110, to facilitate shelling peanuts disposed in the tapered volume between the of inner wall 116 of the cylindrical housing 110 and the outer wall 124 of the drum 120. Actuating cap 130 includes an inlet opening 132 for receiving nuts, such as peanuts into the nut shelling device 100. As the actuating cap 130 turns the drum 120 with respect to the cylindrical housing 110, the nuts descend through the tapered volume 117 and the shells of the nuts disposed in the tapered volume 117 are cracked by the abrasion of the cylinder housing protrusions 111 and the drum protrusions 121 rotating with respect to one another. In various embodiments, the actuating cap 130 may include one or more contours configured as hand or finger grips to facilitate grasping by the user during turning of the actuating cap 130.
As the shells of the nuts are cracked, the kernels are separated from the shells and both the kernels and the shells descend through the cylindrical housing 110. The nut shelling device 100 includes a first sieve 101 coupled to the cylindrical housing generally below the drum 120. The first sieve 101 includes a plurality of holes 102. The holes 102 help separate the cracked shells from the kernels. The holes 102 are sized to allow whole kernels to pass through and prevent shell portions that are larger than the whole kernels from passing through the first sieve 101. Accordingly, the first sieve 101 may be removably coupled to the cylindrical housing to permit a sieve having differently sized holes, in accordance with the desired nut being shelled to be positioned therein. After the kernels and small shell portions traverse the first sieve 101 they descend into a containment receptacle 140. Containment receptacle 140 includes a second sieve 103 that includes a plurality of holes 104. Holes 104 are smaller than holes 102, such that kernels remain on top of the second sieve 103 within the containment receptacle 140 and such that shell portions that are smaller than the kernels and other debris fall through the second sieve 103. For example, in one embodiment holes 102 are approximately 0.450 inches and holes 104 are approximately 0.275 inches. In the illustrated embodiment, the containment receptacle 140 is removably coupled to the cylindrical housing 110 via threaded formations including male threaded formation 113 on the cylindrical housing 110 and female threaded formation 142 on the containment receptacle 140.
In various embodiments, the nut shelling device may include various electrical components configured to facilitate shelling and separation. For example, the nut shelling device 100 may include an actuation motor, such as a motor which may be disposed in actuating cap 130 to rotate the drum 120 with respect to the cylindrical housing 110 via shaft 122. The nut shelling device 100 may also include one or more blower motors, which may be disposed in the cylindrical housing 110 to facilitate separation of small shell portions or debris from the large and/or whole kernel chunks.
As utilized herein, the terms “approximately,” “about,” “substantially” and similar terms are intended to have a broad meaning in harmony with the common and accepted usage by those of ordinary skill in the art to which the subject matter of this disclosure pertains. It should be understood by those of skill in the art who review this disclosure that these terms are intended to allow a description of certain features described without restricting the scope of these features to the precise numerical ranges provided.

It is important to note that the constructions and arrangements of apparatuses or the components thereof as shown in the various example embodiments are illustrative only. Although only a few embodiments have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter disclosed. For example, elements shown as integrally formed may be constructed of multiple parts or elements, the position of elements may be reversed or otherwise varied, and the nature or number of discrete elements or positions may be altered or varied. The order or sequence of any process or method steps may be varied or re-sequenced according to alternative embodiments. Other substitutions, modifications, changes and omissions may also be made in the design, operating conditions and arrangement of the various example embodiments without departing from the scope of the present disclosure.
While various inventive embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other mechanisms and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the inventive embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be examples and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the inventive teachings is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific inventive embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, inventive embodiments may be practiced otherwise than as specifically described and claimed. Inventive embodiments of the present disclosure are directed to each individual feature, system, article, material, kit, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, kits, and/or methods, if such features, systems, articles, materials, kits, and/or methods are not mutually inconsistent, is included within the inventive scope of the present disclosure.
Also, the technology described herein may be embodied as a method, of which at least one example has been provided. The acts performed as part of the method may be ordered in any suitable way unless otherwise specifically noted. Accordingly, embodiments may be constructed in which acts are performed in an order different than illustrated, which may include performing some acts simultaneously, even though shown as sequential acts in illustrative embodiments.
All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms.
The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.”
The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.
As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.
As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.
In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to.
The claims should not be read as limited to the described order or elements unless stated to that effect. It should be understood that various changes in form and detail may be made by one of ordinary skill in the art without departing from the spirit and scope of the appended claims. All embodiments that come within the spirit and scope of the following claims and equivalents thereto are claimed.
The present application claims priority to U.S. Provisional Patent Application No. 61/773,038, filed Mar. 5, 2013 and entitled “PERSONAL PEANUT SHELLER,” which application is incorporated herein by reference in its entirety.
