Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing technology, specifically to a device for imitating manual peeling of torreya nuts. Background Technology

[0002] Currently, most torreya nuts are peeled manually, which is inefficient and slow. Sometimes, when purchasing large quantities, labor shortages lead to rotting and discarding of the nuts. Therefore, machine peeling has emerged. Existing torreya nut peeling devices on the market generally use squeezing or blades, which can cause significant damage to the kernels, resulting in incomplete kernels. Furthermore, torreya nuts have an aril; if this aril is damaged, the taste, aroma, and texture of the kernel will be severely affected. In practical applications, measuring kernel texture is usually not the direct purpose, but rather part of understanding fruit quality, seed development, or processing suitability. For example, in nut research (such as almonds and walnuts), kernel texture may be related to the kernel yield; in some fruits, excessively loose kernels may lead to increased breakage during transportation and storage. However, commercially available torreya nut peeling devices generally damage the aril, resulting in poor kernel quality.

[0003] For example, patent CN118766095A discloses a torreya nut shelling machine, including a frame, a drive mechanism, a feeding hopper, a feeding roller, a discharge rack, and a shelling mechanism. The drive mechanism includes a drive motor, a crankshaft, and a transmission assembly. The drive motor is connected to the crankshaft, and the crankshaft is connected to the transmission assembly. The feeding roller is located at the outlet of the feeding hopper and has a feeding trough assembly. The feeding roller is connected to the transmission assembly. The drive motor drives the discharge rack and the feeding roller to rotate synchronously through the transmission assembly. A collection box is located below the discharge rack to collect the shelled torreya nuts. The shelling mechanism is located above the discharge rack and is connected to the crankshaft. The drive motor drives the shelling mechanism to move up and down through the crankshaft. Utility Model Content

[0004] Technical problem to be solved by the utility model

[0005] The technical problem to be solved by this utility model is to provide a manual peeling device for torreya nuts that can protect the kernel from damage and prevent the aril from being damaged.

[0006] Technical solution

[0007] To solve the above problems, the technical solution provided by this utility model is as follows:

[0008] A simulated manual peeling device for Torreya grandis includes a trough assembly comprising a fixed trough cylinder and a movable trough cylinder that rotate parallel to each other. The surfaces of the fixed and movable trough cylinders are provided with soft sleeves, and the soft sleeves have spaced protrusions. The periphery of each protrusion has slits for accommodating Torreya grandis kernels. The protrusions of the fixed and movable trough cylinders crush the Torreya grandis peel. A separation assembly is located below the trough assembly and includes a separation cylinder and a separation beam cylinder that rotate parallel to each other. The surface of the cylinder is provided with spiral guide strips, which are symmetrically arranged along the center line of the separation cylinder. The symmetrical part of the guide strip is the vertical entrance of the Torreya grandis. The guide strip and the gap cooperate to form a channel to the fruit grooves on both sides. The guide strip and the protrusion cooperate to peel off the Torreya grandis skin. The lower center of the separation cylinder and the separation light cylinder is the skin groove. The distance between the separation cylinder and the separation light cylinder is less than the width of the Torreya grandis kernel. The rotation speed of the separation cylinder and the separation light cylinder is faster than that of the groove cylinder fixed cylinder and the groove cylinder moving cylinder.

[0009] The trough assembly is responsible for crushing the husk of the Torreya grandis and securing the kernel. The fixed cylinder and the moving cylinder rotate in opposite directions, crushing the whole kernel. The gaps can accommodate the kernel, ensuring it is not crushed. A soft sleeve further protects the kernel, giving the gaps some elasticity and allowing for larger kernels, thus improving the versatility for Torreya grandis sizes. The separation assembly separates the kernel from the husk. The spiral guide bar generates thrust in the axial direction of its surface after rotation. Because the distance between the separation cylinder and the separation light cylinder is less than the width of the Torreya grandis kernel, and in conjunction with the surface of the separation light cylinder, the kernel moves axially to both sides at the junction of the separation cylinder and the separation light cylinder, entering the kernel trough. The husk, being fibrous, long, and thin, leaks through the junction of the separation cylinder and the separation light cylinder, entering the husk trough in the lower center. The guide strips are symmetrically distributed from the center of the separating cylinder to both sides, creating a thrust that extends outwards. This effectively tears the skin of the central Torreya nut, mimicking hand peeling and protecting the aril from damage, thus ensuring the quality of the Torreya nut kernel. Torreya nuts not in the center will also be caught in the gaps, and their skin will be continuously scraped and torn off by the guide strips, again mimicking hand peeling. While hand peeling involves tearing, traditional Torreya nut peeling typically involves crushing; this solution uses a scraping and tearing method that mimics hand peeling.

[0010] Optionally, the moving cylinder is provided with a moving shaft, and a moving block is rotatably connected to the end of the moving shaft. The moving block can be adjusted horizontally.

[0011] The horizontal position of the moving cylinder in the trough is adjustable. This feature is designed to adjust the distance between the moving cylinder and the fixed cylinder, allowing for proper crushing of the torreya nut skin without damaging the kernel. The distance between the moving and fixed cylinders should generally be greater than the width of the kernel but less than the width of the whole torreya nut.

[0012] Optionally, the separating light tube is connected to a separating moving block, the separating moving block being horizontally adjustable.

[0013] This setting is to adjust the distance between the separating tube and the separating cylinder, so that the distance between them is less than the width of the pit and greater than the width of the fibrous skin.

[0014] Optionally, the protrusions are rectangular protrusions, and the protrusions are arranged in parallel and staggered. The gaps between the protrusions are divided into axial gaps and vertical gaps. The axial gaps are distributed along the axial direction of the cylinder, and the vertical gaps are perpendicular to the axial gaps.

[0015] The axial gap is used to hold the Chinese torreya nuts in place so that the kernel can be pushed by the guide strip after peeling. The vertical gap is used to hold the Chinese torreya nuts in place during peeling. The peeling methods in different directions are all tearing methods, which are all imitation of manual peeling.

[0016] Optionally, the bumps are divided into large bumps and small bumps, which are arranged alternately.

[0017] The large bumps can crush the skin of the Chinese torreya nuts, while the kernels of the Chinese torreya nuts often do not fit completely into the gaps. The alternating arrangement of large and small bumps can avoid the interference and squeezing between the Chinese torreya nuts due to too small a distance between them, which would cause the kernels to be crushed. It can also avoid the gaps being too far apart due to all large bumps, which would waste the kernel fitting space on the soft sleeve and reduce the peeling efficiency.

[0018] Optionally, the width of the large protrusion is greater than the width of the torreya kernel.

[0019] The width of the large protrusion is greater than the width of the Torreya grandis kernel, which helps to crush the Torreya grandis skin with a larger pressure area, avoids excessive stress, crushes the Torreya grandis more gently, and protects the kernel.

[0020] Optionally, the top corners of the rectangular protrusion are provided with a rounded corner structure.

[0021] The rounded corners prevent excessive stress on sharp parts and protect the pit.

[0022] Optionally, the guide strip is provided with multiple links, each link having a reduced diameter structure, forming an uneven surface on the guide strip for scraping off the bark of the Torreya grandis.

[0023] The narrowing structure creates an uneven surface, which can continuously peel off the bark of the Torreya grandis as the spiral guide bar rotates.

[0024] Optionally, the fixed trough cylinder, the moving trough cylinder, the separating cylinder, and the separating light cylinder are all connected to a drive motor.

[0025] The drive motor provides rotational driving force for the fixed trough cylinder, the moving trough cylinder, the separation cylinder, and the separation light cylinder.

[0026] Beneficial effects

[0027] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0028] The technical solution provided by this utility model uses a soft sleeve and a grooved cylinder fixing cylinder and a grooved cylinder moving cylinder to fix and peel the Chinese torreya nuts, imitating manual peeling. This can protect the kernel from damage and prevent damage to the aril. Furthermore, the guide strips are symmetrically distributed from the center of the separating cylinder to both sides, and the resulting thrust is also directed to both sides, which can tear the skin of the Chinese torreya nut in the center to a great extent and imitate manual peeling, protecting the aril from damage and ensuring the quality of the Chinese torreya nut kernel.

[0037] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0038] Example

[0039] Combined with appendix Figure 1 , 2 A simulated manual peeling device for Chinese torreya nuts includes a frame 1, wheels 101, an opening 102, a protective cover 103, and a drive assembly 2. The wheels 101 are located at the bottom of the frame 1, and the opening 102 is located at the top of the frame 1. The opening 102 has a structure that is wider at the top and narrower at the bottom. The width of the bottom of the opening 102 is the same as the axial length of the fixed cylinder 301 and the moving cylinder 303. The bottom of the opening 102 is also provided with an extended side baffle to ensure that the Chinese torreya nuts enter between the fixed cylinder 301 and the moving cylinder 303.

[0040] Combined with appendix Figure 3-5 The trough assembly 3 includes a parallel and relatively rotatable trough fixed cylinder 301 and a trough movable cylinder 303. The trough movable cylinder 303 is fixedly connected to a trough movable shaft 304. A trough movable block 305 is rotatably connected to the end of the trough movable shaft 304, and the position of the trough movable block 305 can be adjusted horizontally. The end of the trough movable shaft 304 extends out of the frame 1 and is fixedly connected to a pulley. The pulley is connected to a belt drive mechanism via a transmission belt 202, and the belt drive mechanism is connected to a drive motor 201. The trough movable block 305 is slidably connected to a window on the side of the frame 1. The trough movable block 305 itself is rotatably connected to a trough adjusting screw 306 and is axially limited. The trough adjusting screw 306 is threadedly connected to the frame 1, and its position can be adjusted by rotation.

[0041] The grooved cylinder fixing cylinder 301 is connected to the grooved cylinder fixing shaft 302. The end of the grooved cylinder fixing shaft 302 extends out of the frame 1 and is fixedly connected to a pulley. The pulley is connected to the belt drive mechanism through the transmission belt 202. The belt drive mechanism is connected to the drive motor 201. The drive motor 201 and the belt drive mechanism are also provided with a housing.

[0042] The surfaces of the fixed cylinder 301 and the movable cylinder 303 are provided with soft sleeves 307, which are made of rubber. The soft sleeves 307 have spaced protrusions, and the periphery of the protrusions has gaps for accommodating the kernels of the Torreya grandis. The protrusions of the fixed cylinder 301 and the movable cylinder 303 crush the Torreya grandis husks. The kernels are approximately 2 to 3 cm long and 1 to 1.5 cm wide. The whole Torreya grandis is generally between 2.5 and 4 cm long and approximately 1.5 to 2.5 cm in diameter. In this embodiment, the gaps are set to 1 to 1.5 cm, and the distance between the fixed cylinder 301 and the movable cylinder 303 is set to 1.5 to 2.5 cm.

[0043] Combined with appendix Figure 6 The protrusions are rectangular and arranged in a staggered, parallel pattern. The gaps between the protrusions are divided into axial gaps 3010 and vertical gaps. The axial gaps 3010 are distributed along the axial direction of the cylinder, and the vertical gaps are perpendicular to the axial gaps 3010. The protrusions are divided into large protrusions 308 and small protrusions 309, which are arranged alternately. In this embodiment, the width of the large protrusion 308 is twice the width of the small protrusion 309. The vertical gaps include a large vertical gap 3011 and a small vertical gap 3012. The large vertical gap 3011 is the gap between the large protrusions 308 and 308, and the small vertical gap 3012 is the gap between the small protrusions 309 and 309. The Chinese torreya nuts stuck in the large vertical gap 3011 are not easy to turn into the axial gap 3010, while the Chinese torreya nuts stuck in the small vertical gap 3012 are easy to turn into the axial gap 3010. Peeling in multiple directions can improve the quality of peeling.

[0044] The width of the large bump 308 is greater than the width of the Torreya grandis kernel. The width of the large bump 308 is 1.5 cm to 2 cm.

[0045] Both the large protrusion 308 and the small protrusion 309 have rounded corners.

[0046] Combined with appendix Figure 3-5 The separation component 4 includes a parallel and relatively rotating separation cylinder 401 and a separation light cylinder 405. The separation component 4 is located below the trough cylinder component 3. The trough cylinder fixed cylinder 301 corresponds to the separation cylinder 401, and the trough cylinder moving cylinder 303 corresponds to the separation light cylinder 405 and has an intersection. The distance between the trough cylinder fixed cylinder 301 and the separation cylinder 401 is less than 1.5 cm in width.

[0047] The surface of the separating cylinder 401 is provided with a spiral guide bar 408. The guide bar 408 is symmetrically arranged along the center line of the separating cylinder 401. The symmetrical part of the guide bar 408 is the vertical entrance of the torreya nut. The guide bar 408 and the gap cooperate to form a channel to the fruit grooves 404 on both sides. The guide bar 408 cooperates with the protrusion to peel off the torreya nut skin. The skin groove 403 is located in the center below the separating cylinder 401 and the separating light cylinder 405. The skin groove 403 is located in the middle, and the fruit grooves 404 are located on both sides.

[0048] Combined with appendix Figure 7 The distance between the separating cylinder 401 and the separating light cylinder 405 is less than the width of the Torreya grandis kernel. The rotation speed of the separating cylinder 401 and the separating light cylinder 405 is faster than that of the trough cylinder fixed cylinder 301 and the trough cylinder moving cylinder 303. The guide bar 408 is provided with multiple links 409, which are tapered structures, forming an uneven surface on the guide bar 408 for scraping off the Torreya grandis bark.

[0049] The separation cylinder 405 is connected to a separation moving block 406, which can be horizontally adjusted. The separation cylinder 401 is connected to a separation fixed shaft 402. The separation moving block 406 is slidably connected to a window on the side of the frame 1. The separation moving block 406 itself is rotatably connected to the separation adjusting screw 407 and is axially limited. The separation adjusting screw 407 is threadedly connected to the frame 1, and its rotation can adjust the position of the separation moving block 406.

[0050] Working principle:

[0051] Most of the Torreya grandis enters the open opening 102, where the pericarp is initially crushed by the fixed cylinder 301 and the moving cylinder 303. Due to the use of a soft rubber sleeve 307, the harder kernel is preserved, and the aril is not damaged. The crushed pericarp and kernel are stuck in the gaps of the protrusions. The Torreya grandis pericarp is continuously peeled by the spiral guide strip 408, exposing the kernel, which falls between the separation cylinder 401 and the separation light cylinder 405. After the guide strip 408 rotates, it continues to push to both sides, and the Torreya grandis kernel falls into the fruit troughs 404 on both sides. The Torreya grandis pericarp, after being peeled, is fibrous and falls into the peel trough 403 through the gap between the separation cylinder 401 and the separation light cylinder 405, realizing the separation of the kernel and pericarp in a simulated manual manner. A small portion of the Torreya grandis stuck in the axial gap 3010 are peeled off by the spiral guide bar 408, exposing the Torreya grandis kernel. After the guide bar 408 rotates, it is continuously pushed to both sides and falls into the fruit grooves 404 on both sides through the axial gap 3010.

[0052] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
