Abstract
Description
Technical Field
[0001] The present application relates to a tool for removing the skin of nuts, in particular to a tool for removing the inner seed coat of torreya grandis. Background Art
[0002] Torreya grandis is a rare and precious nut. The so-called torreya grandis refers to the torreya grandis nuts sold in the market, which are the seed kernels of torreya grandis.
[0003] Please refer to Figure 1 , the seed kernel of torreya grandis from outside to inside successively includes: outer seed coat, inner seed coat, endosperm. The outer seed coat refers to the shell (fruit shell) of the torreya grandis nut, which is yellowish-brown and very hard in texture. The inner seed coat is inside the outer seed coat and tightly wraps the surface of the endosperm. The texture of the inner seed coat is relatively hard, generally grayish-black, and is commonly called the black coat (seed coat) of torreya grandis. The endosperm refers to the kernel (seed kernel, pulp) of the torreya grandis nut, that is, the edible part, which is yellowish-white, relatively soft in texture, and widely has folds and depressions on the surface.
[0004] Since the black coat of the torreya grandis nut tightly wraps the surface of the kernel, and the surface of the kernel is covered with folds and depressions, the black coat also grows into the folds and depressions on the surface of the kernel, which makes it very difficult to completely remove the black coat of the torreya grandis nut.
[0005] Currently, the black coat of torreya grandis is mainly peeled off using the shell of the torreya grandis nut or the nails of workers as tools, and the removal effect is not ideal. Utility Model Content
[0006] The technical problem to be solved by the present application is how to conveniently and thoroughly remove the black coat of torreya grandis.
[0007] To solve the above technical problem, the present application provides a tool for removing the black coat of torreya grandis, which is integrally in the shape of a cap, with one end being a closed end and the other end being an open end; the inner cavity formed by the open end is used to place at least half of the torreya grandis seed kernel after removing the shell; a plurality of convex ridges are provided in the inner cavity of the tool, and saw teeth are provided on the circumference of the open end.
[0008] Further, if the line connecting the center of the closed end and the center of the open end is used as the axis of the tool, after at least half of the torreya grandis seed kernel after removing the shell is inserted into the inner cavity of the tool, when the tool or the torreya grandis seed kernel after removing the shell is rotated around the axis, the most prominent ridge line of the convex ridge scrapes the black coat of torreya grandis perpendicular to the rotation direction of each convex ridge.
[0009] Further, when the saw teeth are perpendicular to the torreya grandis seed kernel after removing the shell and slide forcefully on the surface of the torreya grandis seed kernel after removing the shell, it also scrapes the black coat of torreya grandis.
[0010] Further, the convex ridges are all formed along the direction from the open end to the closed end; if the line connecting the center of the closed end and the center of the open end is taken as the axis of the tool, then the most prominent ridge line of each convex ridge and the axis of the tool are in the same plane.
[0011] Preferably, the cross-sectional shape of the convex ridge is triangular.
[0012] Further, the convex ridges are evenly distributed around the center of the closed end, and the most prominent ridge lines of all the convex ridges finally converge at a point, and this convergence point corresponds to the center of the closed end inside and outside.
[0013] Optionally, a plurality of grooves are provided on the outer surface of the tool, and the grooves are all formed along the direction from the closed end to the open end; if the line connecting the center of the closed end and the center of the open end is taken as the axis of the tool, then the center line of each groove and the axis of the tool are in the same plane.
[0014] Further, if the line connecting the center of the closed end and the center of the open end is taken as the axis of the tool, when the outer surface of the tool is pinched by a finger and the tool is driven to rotate around the axis, the rotation direction is perpendicular to the center line of each groove. Or, when the finger pinches the torreya grandis seed kernel after removing the shell and drives the torreya grandis seed kernel after removing the shell to rotate around the axis in the inner cavity of the tool, the rotation direction is also perpendicular to the center line of each groove.
[0015] Further, the grooves are evenly distributed around the center of the closed end.
[0016] Preferably, each convex ridge and each groove correspond to each other inside and outside; this means that the inwardly concave part of each groove is exactly the inwardly convex part of each convex ridge.
[0017] The technical effects achieved by this application are: improving the efficiency of removing the black skin of torreya grandis and enhancing the effect of removing the black skin of torreya grandis. BRIEF DESCRIPTION OF THE DRAWINGS
[0018] Figure 1 is a schematic structural diagram of a torreya grandis seed kernel.
[0019] Figures 2 - 5 is a schematic diagram of the tool for removing the black skin of torreya grandis proposed by this application.
[0020] Explanation of the reference numerals in the drawings: 10 is the closed end, 11 is the groove, 20 is the open end, 21 is the convex ridge, 21a is the convergence point, and 22 is the serration. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] Please refer to Figures 2 to 5, the tool for removing torreya grandis' black skin proposed in this application is in a cap shape as a whole, with one end being the closed end 10 and the other end being the open end 20. For example, the tool as a whole is in a semi-ellipsoidal shape. The diameter of the open end 20 is slightly larger than the maximum diameter of any torreya grandis seed after removing its shell, and the depth of the inner cavity formed by the open end 20 is slightly larger than half of the maximum length of any torreya grandis seed after removing its shell. In this way, at least half of any torreya grandis seed after removing its shell in the length direction can penetrate into the inner cavity inside the open end 20.
[0022] Please refer to Figure 4 and Figure 5 , in the inner cavity formed by the open end 20, there are multiple convex ridges 21, and these convex ridges 21 are all arranged along the direction from the open end 20 to the closed end 10. The cross-section of each convex ridge 21 is, for example, triangular, preferably an isosceles triangle. If the line connecting the center of the closed end 10 and the center of the open end 20 is taken as the axis of the tool, the most prominent ridge line of each convex ridge 21 and the axis of the tool are in the same plane, and these convex ridges 21 are similar to the rib structure after an umbrella is opened. After stuffing at least half of the torreya grandis seed after removing its shell into the inner cavity of the tool, rotating the tool around the axis, or rotating the torreya grandis seed after removing its shell around the axis, then these convex ridges 21 scrape the black skin of the torreya grandis in a direction substantially perpendicular to the rotation direction of each convex ridge 21. In an ideal situation, the most prominent ridge line of each convex ridge 21 scrapes the black skin of the torreya grandis from beginning to end, so as to achieve the best effect of removing the black skin of the torreya grandis.
[0023] Please refer to Figures 2 to 5 , the open end 20 of the tool has a circular cross-section, and sawteeth 22 are provided on the entire circumference of the edge of the circular cross-section. When these sawteeth 22 are slid forcefully on the surface of the torreya grandis seed after removing its shell perpendicular to the torreya grandis seed after removing its shell, the black skin of the torreya grandis can be scraped.
[0024] As a preferred example, the convex ridges 21 are evenly distributed around the center of the closed end 10. For example, one convex ridge 21 is provided every 60 degrees, so a total of six convex ridges 21 are provided on the entire circumference of 360 degrees. The most prominent ridge lines of all convex ridges 21 finally converge at a point 21a, and this convergence point 21a corresponds to the center of the closed end 10 inside and outside.
[0025] When in use, at least half of the torreya grandis seed kernel after removing the shell is stuffed into the inner cavity inside the open end 20. Then, pinch the outer surface of the tool with fingers and drive the tool to rotate around the axis, or pinch the torreya grandis seed kernel after removing the shell with fingers and drive the torreya grandis seed kernel after removing the shell to rotate around the axis in the inner cavity of the tool. At this time, the most prominent ridge lines of each ridge 21 in the inner cavity of the tool play the role of scraping off the black skin of the torreya grandis. Then, replace the other half of the torreya grandis seed kernel after removing the shell and perform the same operation. This step can remove most of the black skin of the torreya grandis. Then, take out the torreya grandis seed kernel with most of the black skin removed from the inner cavity inside the open end 20, and use the serrations 22 of the tool to be perpendicular to the torreya grandis seed kernel with most of the black skin removed and scrape forcefully on the surface of the torreya grandis seed kernel with most of the black skin removed to completely remove the remaining small part of the black skin of the torreya grandis.
[0026] Optionally, a plurality of grooves 11 are provided on the outer surface of the tool. These grooves 11 are all arranged along the direction from the closed end 10 to the open end 20. They may not penetrate both ends, or they may penetrate both ends. The center line of each groove 11 and the axis of the tool are in the same plane. When pinching the outer surface of the tool with fingers, these grooves 11 provide enhanced friction for the fingers. When pinching the outer surface of the tool with fingers and driving the tool to rotate around the axis, the rotation direction is basically perpendicular to the center lines of each groove 11. Therefore, these grooves 11 provide the most ideal anti-slip effect. Or, when pinching the torreya grandis seed kernel after removing the shell with fingers and driving the torreya grandis seed kernel after removing the shell to rotate around the axis in the inner cavity of the tool, the rotation direction is also basically perpendicular to the center lines of each groove 11. Therefore, these grooves 11 provide the most ideal anti-slip effect.
[0027] As a preferred example, the grooves 11 are evenly distributed around the center of the closed end 10. For example, one groove 11 is provided every 60 degrees, so a total of six grooves 11 are provided in the entire circumference of 360 degrees.
[0028] As a preferred example, each ridge 21 and each groove 11 correspond to each other inside and outside. In other words, the inwardly concave part of each groove 11 is exactly the inwardly convex part of each ridge 21.
[0029] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
