Description

Technical Field

[0001] This application relates to the field of food manufacturing technology, and in particular to a fresh Sichuan peppercorn pounding device and a Sichuan peppercorn oil production line. Background Technology

[0002] Sichuan peppercorn oil is a traditional condiment widely used in Chinese cuisine, and it is loved by consumers for its unique numbing and fragrant flavor.

[0003] In the preparation of Sichuan pepper oil, especially when using cold or warm maceration extraction methods, fresh Sichuan pepper, as the main raw material, directly affects the dissolution efficiency of flavor compounds due to the integrity of its cell structure. The outer layer of the fresh Sichuan pepper fruit is a dense epidermal tissue, rich in volatile oils and functional substances such as amide-based numbing compounds (e.g., hydroxy-α-sanshool). These flavor components are mainly found in the oil gland cells beneath the pericarp. Due to the barrier effect of the cell walls and epidermis, if whole fresh Sichuan peppers are directly immersed in edible oil, the oil cannot quickly penetrate into the cells, resulting in slow dissolution of active ingredients, a long extraction cycle (usually several days to weeks), and a low extraction rate, severely impacting production efficiency and product flavor intensity.

[0004] Therefore, appropriate physical pretreatment of fresh Sichuan peppercorns before extraction, especially by methods such as beating, crushing, or micro-cell disruption to break down their epidermal structure and oil gland cells, has become a key step in improving the quality of Sichuan peppercorn oil. After beating, the pericarp of fresh Sichuan peppercorns cracks or is partially broken, exposing the cell contents, which greatly increases the contact area with the oil, significantly accelerates the diffusion and dissolution of the numbing and aromatic components, shortens the extraction time, and improves oil yield and flavor intensity.

[0005] However, traditional patting methods rely heavily on manual methods using tools such as wooden mallets and rolling pins to strike the container, which presents the following problems: 1. Uneven force and excessive damage: It is difficult to control the intensity of patting by manual operation, which can easily cause the pepper to be completely broken or even turned into mud. This results in too many seeds breaking and releasing bitter substances, affecting the taste of Sichuan pepper oil.

[0006] 2. Low processing efficiency: small processing volume per batch, high labor intensity, and cannot meet the needs of continuous industrial production. Utility Model Content

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] refer to Figures 1 to 5 This application discloses a fresh pepper-beating device, which includes a frame 100, a conveying mechanism 200 and a beating mechanism; The conveying mechanism 200 is mounted on the frame 100 and has a conveying surface for conveying fresh Sichuan peppercorns along the first direction X; The tapping mechanism includes a reciprocating drive assembly 300 and a tapping assembly 400 connected together; the tapping assembly 400 is located above the conveying mechanism 200; The reciprocating drive assembly 300 is mounted on the frame 100 and is used to drive the tapping assembly 400 to reciprocate linearly along the second direction Z, so that the tapping assembly 400 intermittently and elastically taps the fresh peppercorns on the conveying surface, wherein the second direction Z is perpendicular to the conveying surface.

[0030] In this way, driven by the reciprocating drive component 300, the patting component 400 reciprocates linearly along the second direction Z perpendicular to the conveying surface, intermittently and elastically patting the fresh Sichuan peppercorns on the conveying surface. This can create micro-cracks or local ruptures in the peppercorn peel without completely destroying the peppercorn structure, effectively opening the oil gland cells, exposing the internal flavor substances, increasing their contact area with edible oil, accelerating the dissolution rate of the numbing and aromatic components, shortening the time of subsequent extraction processes, improving extraction efficiency and oil yield, and ensuring the taste of the Sichuan peppercorn oil. Meanwhile, the fresh Sichuan peppercorns are continuously conveyed along the first direction X by the conveying mechanism 200, and in conjunction with the reciprocating motion of the patting component 400 above, a production line operation mode of conveying and patting at the same time is formed. Without manual intervention, large-scale automated processing of fresh Sichuan peppercorns can be achieved, reducing labor intensity, increasing processing capacity per unit time, and meeting the needs of industrialized and large-scale production.

[0031] The frame 100 serves as the supporting foundation for the entire fresh pepper pounding equipment. It can be constructed by assembling multiple rectangular tubes through welding, bolting, or snap-fitting to form a stable frame structure.

[0032] Rectangular tubes can be made of metal (such as Q235 carbon steel or 304 stainless steel), with a rectangular or square cross-section, and have high bending and torsional stiffness. The rectangular tubes can be combined according to the equipment layout requirements using right-angle connections, diagonal bracing reinforcement, or modular assembly to form a three-dimensional support frame including the base frame, side supports, and top beams.

[0033] In actual manufacturing, rectangular tubes can be precisely processed through CNC cutting, bending and welding processes to ensure the overall size stability of the frame 100 and the accuracy of the installation benchmark, providing reliable support for the assembly of the conveying mechanism 200 and the tapping mechanism.

[0034] In this embodiment, the tapping assembly 400 includes a connecting seat 410, an elastic element 420, and a pressure plate 430; The connecting seat 410 is located above the conveying mechanism 200 and is connected to the reciprocating drive assembly 300; The pressure plate 430 is connected to the side of the connecting seat 410 near the conveying surface via the elastic element 420; The reciprocating drive assembly 300 is used to drive the connecting seat 410 to reciprocate linearly along the second direction Z, so that the connecting seat 410 drives the pressure plate 430 to intermittently pat the fresh peppercorns on the conveying surface.

[0035] Thus, the pressure plate 430 is connected to the connecting seat 410 via an elastic element 420 (such as a spring, rubber pad, polyurethane buffer block, or metal spring), forming a flexible tapping structure. Driven by the reciprocating drive assembly 300, the pressure plate 430 intermittently and elastically taps the fresh peppercorns on the conveying surface. This applies sufficient impact force to damage the oil glands in the peel while the elastic element 420 absorbs excessive impact energy, preventing rigid collisions from causing the peppercorns to shatter, the seeds to break, or a large amount of juice to leak out. This maximizes the preservation of the fresh peppercorns' shape and structural stability, prevents the dissolution of bitter substances, and ensures the pure taste and high quality of the subsequent peppercorn oil.

[0036] Meanwhile, the pressure plate 430, supported by the elastic element 420, can adaptively adjust the distance between itself and the conveying surface. When encountering material layers of uneven thickness, it can still maintain a relatively consistent tapping depth and contact pressure, avoiding local missed tapping or excessive tapping, ensuring that the entire batch of fresh peppercorns is subjected to uniform force, with stable processing effect and consistent quality between batches.

[0037] It should also be noted that the elastic element 420 plays a buffering role during the tapping process, which can reduce the mechanical impact between the tapping component 400 and the frame 100, reduce the overall vibration and noise of the equipment, prevent structural components from fatigue damage due to long-term alternating loads, extend the service life of key components (such as drive mechanism and connecting parts), and improve the stability and reliability of equipment operation.

[0038] Optionally, the tapping assembly 400 also includes an adjusting screw 440 and a nut 441. The adjusting screw 440 is slidably disposed in the connecting seat 410 along the second direction Z, and the lower end of the adjusting screw is threadedly connected to the pressure plate 430 (for example, the end of the screw is screwed into a threaded hole on the pressure plate 430). The nut 441 is threadedly connected to the adjusting screw 440, and the nut 441 can abut against the side of the connecting seat 410 opposite to the pressure plate 430 under the action of the elastic member 420.

[0039] In this way, by rotating the adjusting screw 440 and nut 441, the extension length of the adjusting screw 440 relative to the connecting seat 410 towards the conveying surface can be changed, thereby driving the pressure plate 430 to move up and down as a whole, achieving precise adjustment of the initial distance between the pressure plate 430 and the conveying surface. This distance directly determines the lower limit of the patting stroke and the pre-compression of the elastic element 420. The greater the pre-compression, the stronger the impact force applied during patting; conversely, the less pre-compression, the gentler the impact. This, in turn, affects the patting force. Therefore, in actual operation, the height position of the pressure plate 430 can be preset according to the variety, maturity, moisture content, and target cell wall breaking degree of fresh peppercorns to obtain the best patting effect. For example, lightly patting tender peppers and heavily patting mature peppers improves process adaptability and product consistency.

[0040] If the elastic element 420 is a tubular elastic element such as a spring or bellows, then the elastic element 420 is sleeved outside the adjusting screw 440 (that is, the adjusting screw 440 passes through the inner hole of the tubular elastic element) and is located between the connecting seat 410 and the pressure plate 430, forming a stacked structure of connecting seat 410—elastic element 420—pressure plate 430. Specifically, the upper end of the elastic element 420 abuts against or is fixed to the lower surface of the connecting seat 410, and the lower end abuts against or is limited to the upper surface of the pressure plate 430; the adjusting screw 440 passes through the inner cavity of the elastic element 420, and its lower end is threadedly connected to the pressure plate 430.

[0041] Thus, when the adjusting screw 440 is rotated, it drives the pressure plate 430 to move up and down, thereby compressing or releasing the elastic element 420 and adjusting the preload. This arrangement makes full use of the adjusting screw 440 as a central support shaft, so that the elastic element 420 remains axially aligned during compression and rebound, avoiding uneven loading or lateral bending, and improving operational stability and service life.

[0042] In this embodiment, the tapping mechanism further includes a limiting plate 450 disposed on the frame 100, and the limiting plate 450 and the connecting seat 410 are in movable contact in the first direction X. That is, the limiting plate 450 is disposed on one or both sides of the connecting seat 410 in the first direction X, and the limiting plate 450 and the connecting seat 410 maintain a small gap or slight contact. When the connecting seat 410 moves along the second direction Z under the drive of the reciprocating drive assembly 300, the limiting plate 450 constrains the horizontal position of the connecting seat 410.

[0043] In this way, if the tapping component 400 experiences slight horizontal swaying or displacement due to impact reaction force or assembly error during high-frequency reciprocating motion, the limiting plate 450 can laterally limit the connecting seat 410 to prevent it from shifting in the first direction X conveying direction, ensuring that the pressure plate 430 is always aligned with the center area of ​​the conveying surface, avoiding uneven processing or impact on the conveying mechanism 200 caused by tapping position deviation, and improving operational stability and consistency.

[0044] The connecting seat 410 is equipped with a rolling ball 460, which contacts the limiting plate 450. This rolling contact between the ball 460 and the limiting plate 450 results in a friction coefficient far lower than that between metals, effectively reducing the additional resistance caused by lateral constraints during the reciprocating motion of the striking assembly 400. This leads to a lower load on the drive mechanism, smoother operation, avoidance of vibration or impact due to jamming, and improved uniformity and stability of the striking rhythm.

[0045] Among them, the ball 460 can be rotatably disposed on the side of the connecting seat 410 through the ball 460 seat, the cage or the embedded mounting structure, and its outer surface protrudes from the body of the connecting seat 410.

[0046] The ball bearing 460 is made of high-hardness stainless steel (such as GCr15) or ceramic material, which has good wear resistance and fatigue resistance. The installation position of the ball bearing 460 corresponds to the inner side of the limit plate 450, ensuring that it always maintains contact and rolling throughout the entire stroke of the connecting seat 410.

[0047] Of course, the patting assembly 400 is not limited to the structure of the pressure plate 430, elastic element 420 and connecting seat 410 mentioned above. In some embodiments, the patting assembly 400 may adopt other equivalent structural forms according to actual application requirements, material characteristics or equipment layout. As long as it can realize the intermittent patting function of fresh peppercorns on the conveying surface, it is within the protection scope of this application.

[0048] For example, the patting component 400 can adopt a flexible patting belt or patting chain structure, which is driven by the reciprocating drive component 300 to swing back and forth or vibrate up and down in the vertical plane, using its flexibility to gently pat the fresh peppercorns.

[0049] For example, the design is a pneumatic tapping head, which uses a solenoid valve to control compressed air to drive the piston rod (at this time, the reciprocating drive component 300 is a cylinder) to drive the tapping plate to move up and down, so as to achieve precise frequency and stroke control, which is suitable for production environments with high cleanliness requirements; Alternatively, a rubber hammer array or silicone clapper can be directly connected to the reciprocating drive assembly 300, using the elasticity of the material itself to achieve buffering and clapping, eliminating the need for the design of an independent elastic element 420.

[0050] In addition, the movement mode of the striking component 400 can also be vertical linear reciprocating, oblique impact, swinging striking or vibrating striking, etc., and its power source (reciprocating drive component 300) can be a motor and crank 320 slider mechanism, cam mechanism, cylinder, linear motor or electromagnetic drive device.

[0051] All of the above-mentioned patting structures can effectively break down the epidermal structure of fresh Sichuan pepper and open the oil gland cells, which is conducive to the efficient extraction of Sichuan pepper oil. At the same time, the patting intensity and frequency can be adjusted according to the process requirements to balance processing efficiency and raw material integrity.

[0052] In this embodiment, the reciprocating drive assembly 300 is in the form of a motor-driven crank 320 slider structure. Specifically, the reciprocating drive assembly 300 includes a reciprocating drive motor 310, a crank 320, a connecting rod 330, and a transmission rod 340. The reciprocating drive motor 310 is mounted on the frame 100 and located below the conveying mechanism 200; One end of the crank 320 is connected to the reciprocating drive motor 310, and the other end of the crank 320 is hinged to one end of the connecting rod 330; The other end of the connecting rod 330 is hinged to one end of the transmission rod 340; The other end of the transmission rod 340 is fixedly connected to the beater assembly 400; The transmission rod 340 is movably mounted on the frame 100 along the first direction X and is located on the side of the conveying mechanism 200.

[0053] In this way, the reciprocating drive motor 310 is located below the conveying mechanism 200, which can make full use of the space at the bottom of the equipment and avoid occupying the upper operating area, making the overall layout compact and the center of gravity stable. When the reciprocating drive motor 310 starts, its output shaft drives the crank 320 to rotate. The crank 320 pushes the transmission rod 340 to reciprocate linearly along the second direction Z through the connecting rod 330. Since the transmission rod 340 is rigidly connected to the patting assembly 400, it drives the patting assembly 400 to move up and down periodically along the second direction Z (vertical direction), realizing the intermittent patting of fresh peppercorns on the conveying surface.

[0054] The frame 100 is equipped with a guide wheel assembly for auxiliary guidance and lateral constraint of the reciprocating motion of the transmission rod 340. The guide wheel assembly includes a first guide wheel 110 and a second guide wheel 120 arranged at intervals along the first direction X. Both the first guide wheel 110 and the second guide wheel 120 are rotatably mounted on the frame 100, and the rotation axis of the guide wheels is perpendicular to the first direction X and the second direction Z. The transmission rod 340 is sandwiched between the first guide wheel 110 and the second guide wheel 120, that is, the two guide wheels are located on both sides of the transmission rod 340, forming a "clamping" contact structure.

[0055] Thus, when the transmission rod 340 reciprocates linearly along the first direction X under the drive of the crank 320 and connecting rod 330, its sidewall rolls into contact with the wheel surfaces of the first guide wheel 110 and the second guide wheel 120. The guide wheels provide lateral support and motion guidance, suppressing lateral swaying or torsion caused by uneven force or inertia during reciprocating motion. This ensures that the transmission rod 340 moves strictly along the first direction X, thereby guaranteeing the accuracy and consistency of the vertical striking of the striking assembly 400. Moreover, the rolling contact of the guide wheels has a certain self-adaptive capability, which can absorb the slight positional deviation of the transmission rod 340 during installation or operation, avoiding jamming or stress concentration caused by rigid jamming, and improving the reliability and stability of the equipment operation. At the same time, the rolling contact between the transmission rod 340 and the guide wheels has a low coefficient of friction, which can effectively reduce the additional resistance during reciprocating motion, making the drive motor load smaller, the operation smoother, and improving energy utilization efficiency.

[0056] Optionally, the outer ring of the guide wheel is covered with wear-resistant elastic materials such as polyurethane, rubber or nylon to increase friction, reduce metal wear, and provide a certain degree of cushioning performance.

[0057] In this embodiment, the device can be configured with multiple tapping components 400 operating in parallel to expand the tapping area and increase the processing capacity per unit time. Each tapping component 400 has a connecting seat 410 with two connection points along its own length, and each side is fixedly connected to a transmission rod 340 to achieve dual-point support and drive.

[0058] The reciprocating drive assembly 300 also includes a linkage rod 350, which is a rigid rod horizontally positioned below the conveying mechanism 200 and above the reciprocating drive motor 310. The connecting rod 330 is hinged to the middle of the linkage rod 350, and the two ends of the linkage rod 350 are respectively connected to one end of a transmission rod 340.

[0059] Thus, when the reciprocating drive motor 310 drives the crank 320 to rotate, the crank 320 pushes the linkage rod 350 to reciprocate linearly along the first direction X through the connecting rod 330. Since the linkage rod 350 is a rigid structure, its two ends move synchronously, thereby driving the two transmission rods 340 to reciprocate with the same stroke and the same phase. Finally, the two transmission rods 340 together drive the connecting seat 410 of a tapping assembly 400 to reciprocate up and down, realizing coordinated tapping of fresh peppercorns on the conveying surface. Among them, the connecting seat 410 of each tapping assembly 400 is driven by the transmission rods 340 on both sides, forming a structure of double-sided force and symmetrical transmission, effectively avoiding the phenomenon of uneven load, tilting or torsion that may be caused by single-point drive, ensuring that the pressure plate 430 always maintains a horizontal posture during the tapping process, with uniform tapping force, and preventing local overpressure or missed tapping.

[0060] Optionally, the linkage 350 is made of rectangular tube or round steel, which has sufficient bending stiffness to ensure consistent movement at both ends.

[0061] Of course, it is understood that the reciprocating drive assembly 300 is not limited to the crank 320 slider mechanism described above. In some embodiments, the reciprocating drive assembly 300 may adopt other drive forms that can realize linear reciprocating motion, depending on the actual working conditions, spatial layout, control accuracy or cost requirements. As long as it can drive the striking assembly 400 to perform intermittent elastic striking along the second direction Z, it falls within the protection scope of this application.

[0062] For example, the reciprocating drive assembly 300 can adopt a cam-follower mechanism: the eccentric cam is driven to rotate by a motor, which pushes the roller follower to move up and down, thereby driving the patting assembly 400 to achieve periodic patting. This structure has strong design flexibility in motion law and is suitable for scenarios with specific requirements for patting stroke and acceleration.

[0063] For example, a pneumatic drive can be used: a double-acting cylinder, whose piston rod is directly or indirectly connected to the striking assembly 400, achieving reciprocating extension and retraction under the control of a solenoid valve. Pneumatic systems offer fast response, convenient adjustment, and overload protection, making them suitable for production environments requiring high cleanliness or explosion-proof features.

[0064] For example, linear motor drives can be used to directly output reciprocating linear motion without the need for intermediate conversion mechanisms. This results in a short transmission chain, high precision, and rapid response. It supports digital control and real-time frequency and amplitude modulation, making it suitable for high-end equipment requiring intelligent and high-precision control.

[0065] Alternatively, an eccentric block vibration mechanism can be used: an eccentric mass block is set on the rotating shaft, and a motor drives it to rotate at high speed to generate periodic excitation force, causing the striking component 400 to reciprocate under elastic support. This structure is simple, low-cost, and suitable for light-load, high-frequency striking scenarios.

[0066] All of the above driving methods can effectively drive the beating component 400. Its motion frequency, stroke and force can be adjusted according to process requirements to adapt to the processing requirements of different varieties of fresh peppercorns, ensuring that excessive damage is avoided while effectively breaking the cell walls.

[0067] In this embodiment, the conveying mechanism 200 includes a conveying drive motor 210, a driving wheel 220, a driven wheel 230, a conveyor belt, and a support member 250; The conveyor drive motor 210 is mounted on the frame 100 and connected to the drive wheel 220; Both the driving wheel 220 and the driven wheel 230 are rotatably mounted on the frame 100, and the driving wheel 220 and the driven wheel 230 are spaced apart along the first direction X; The conveyor belt is wound around the driving wheel 220 and the driven wheel 230, and is divided into an upper layer and a lower layer by the driving wheel 220 and the driven wheel 230. The upper surface of the upper layer serves as the conveying surface; the lower layer is the return section.

[0068] The support member 250 is fixedly connected to the frame 100 and is located between the upper and lower layers.

[0069] In this way, a highly efficient and reliable material conveying system is constructed through the driving wheel 220, the guiding wheel 230, and the cyclic operation of the circular conveyor belt. The upper layer of the conveyor belt serves as the working section for material conveying, while the lower layer serves as the non-working section for belt return. The structure is reasonable and the operation is stable. The support component 250 supports the bottom of the upper conveyor belt, effectively preventing local depressions or vibrations caused by the conveyor belt's own weight or impact after carrying fresh peppercorns. This ensures that the conveying surface remains horizontal and stable, avoiding differences in impact force due to uneven material layer thickness and improving processing uniformity.

[0070] Optionally, the support member 250 includes a support base plate 251 and a plurality of support plates 252 disposed on the support base plate 251. The length direction of the support base plate 251 and the length direction of the support plate 252 are along the first direction X; the cross-section of the support plate 252 is approximately Z-shaped, and the two sides of the support plate 252 are connected to the support base plate 251 by welding, bending and forming in one piece or fastener connection. The support base plate 251 is connected to the frame 100, and the support plate 252 is located on the side of the support base plate 251 facing the upper layer of the conveyor belt.

[0071] In this way, the support base plate 251, as the load-bearing component of the entire support structure, supports the bottom of the upper conveyor belt throughout or over a large area through the support plate 252, effectively resisting the weight of the material and the periodic impact load of the slapping component 400, preventing the conveyor belt from flexing or vibrating due to excessive span in the middle, ensuring that the conveying surface is always flat and guaranteeing the uniformity of slapping.

[0072] Understandably, the support member 250 can also be a single plate structure located between the upper and lower layers, with its edge connected to the frame 100, thereby supporting the upper layer of the entire conveyor belt.

[0073] Of course, in some embodiments, the support member 250 can also be other structural forms that can provide effective support for the bottom of the upper conveyor belt, for example: Support 250 can be an array of idlers: multiple freely rotatable idlers are arranged side by side along the first direction X, and the conveyor belt rolls on them, which significantly reduces frictional resistance and is suitable for long-distance or high-speed conveying scenarios. Support component 250 can be a support rail: made of one-piece molded metal or engineering plastic, with a smooth and wear-resistant surface, providing continuous surface contact support, compact structure, and easy cleaning; Support 250 can be a grid-like support plate 252: using perforated plate or welded mesh plate, which provides surface support and facilitates drainage and ventilation, preventing the accumulation of moisture or debris; Support component 250 can also be an air flotation support device: by spraying compressed air into the bottom of the conveyor belt to form an air film, non-contact support is achieved with minimal friction, making it suitable for applications requiring high cleanliness.

[0074] In other words, as long as the support member 250 can support the upper conveyor belt and prevent it from sagging or deforming under load or impact, it falls within the scope of protection of this application.

[0075] Furthermore, the conveying mechanism 200 is not limited to the belt conveyor structure consisting of the conveyor drive motor 210, drive wheel 220, driven wheel 230, conveyor belt, and support member 250 described above. In other alternative embodiments, the conveying mechanism 200 may also adopt other equivalent forms, such as chain conveyor, vibrating conveyor, or other continuous conveying forms such as crawler conveyor, mesh belt conveyor, etc.

[0076] All of the above-mentioned conveying structures can stably convey fresh peppercorns along the first direction X to the patting area, and work with the patting mechanism to complete intermittent elastic patting operations. The specific selection can be flexibly determined according to the production cycle, material characteristics, spatial layout and hygiene requirements.

[0077] This application also discloses a Sichuan pepper oil production line, which includes the fresh Sichuan pepper pounding equipment described in the above embodiments.

[0078] In summary, the fresh Sichuan pepper pounding equipment and Sichuan pepper oil production line of this application embodiment can achieve gentle, uniform, and controllable intermittent elastic pounding while ensuring the basic integrity of the pepper body, effectively opening the oil gland channels and providing a reliable guarantee for the rapid, efficient, and high-quality extraction of Sichuan pepper oil.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
