Description

Technical Field

[0001] This invention relates to the field of agricultural and sideline product pickling technology, and in particular to a pickling device and method for agricultural and sideline food processing. Background Technology

[0002] Pickling equipment for agricultural and sideline food processing is a key piece of equipment in modern food industry for pickling meat and other agricultural products, significantly improving the efficiency and quality of traditional pickling processes. The core of this equipment lies in creating a uniform, stable, and controllable pickling environment through automated and intelligent control. Its main structure includes a sealed pickling container, a high-efficiency pickling liquid circulation system, precise temperature and pressure control units, and an intelligent central controller. During operation, it uses stirring to ensure a continuous and uniform flow of brine, sauces, and other pickling liquids among the ingredients, thus completely solving problems such as uneven penetration and long spoilage periods inherent in traditional static pickling. This dynamic pickling mode greatly shortens processing time and improves production efficiency. Simultaneously, the intelligent system can precisely monitor and adjust key parameters such as the concentration, temperature, and pressure of the pickling liquid, ensuring that each batch of finished products has a stable and uniform flavor, color, and texture, achieving standardized production. Furthermore, the sealed, hygienic design effectively reduces microbial contamination and the intrusion of external impurities, better preserving the nutritional components of the ingredients, significantly improving product safety and extending shelf life.

[0003] Traditional marinating machines are widely used in the agricultural and sideline food processing industry, but due to limitations in their structure and working principle, they often have some problems that cannot be ignored. Current mainstream marinating machines, when processing meat, mainly rely on the rotation of the drum, causing the meat pieces to be repeatedly lifted and fall freely within the drum by gravity. However, this traditional method has two significant technical bottlenecks. First, during the continuous rotation of the drum, the inner and outer layers of meat pieces, affected by centrifugal force and friction, gradually stick together and become entangled, eventually forming a large clump. This large clump of meat rolling within the drum severely hinders the free flow and even distribution of the marinade. The direct consequence is that the surface meat pieces can quickly come into contact with the marinade, while the meat pieces deep inside rely mainly on the slow penetration and diffusion of the external marinade. This greatly prolongs the overall marinating time and easily leads to uneven flavor penetration throughout the product. Second, the force mode of existing equipment is relatively simple, mainly relying on gentle tumbling, lacking high-intensity, high-frequency vertical vibration or mechanical beating. This gentle tumbling method, while promoting tenderization of the meat's surface, struggles to effectively tear apart the deep fibrous tissue within the muscle. Therefore, its tenderizing effect is limited in firmer cuts, failing to achieve a deeper level of softness and juiciness. These two drawbacks together restrict further improvements in marinating efficiency and product quality. Summary of the Invention

[0004] In view of the problem that existing marinating machines lack the function of preventing clumping and breaking the internal fibers of meat, a marinating device for agricultural and sideline food processing is proposed.

[0005] The purpose is to prevent ingredients from clumping together during marinating and to break down the fibers of meat, thereby increasing the tenderness of the ingredients.

[0006] The technical solution of the present invention is a pickling device for processing agricultural and sideline food products, including a pickling machine body, a material trough disposed inside the pickling machine body, and an auxiliary mechanism; The auxiliary mechanism includes a motor located on the side of the marinating machine body away from the material tank, an outer sleeve located on the inner wall of the material tank away from the motor, an inner sleeve located on the side of the marinating machine body close to the motor, a collar symmetrically arranged in the middle of the outer sleeve, four stirring rods arranged in a ring array on the outside of the collar, an outer toothed ring located on the inner side of the collar, an inner toothed ring located on the side of the inner sleeve close to the motor, toothed shafts arranged obliquely and symmetrically inside the outer sleeve, the ends of the two toothed shafts that are far apart from each other respectively meshing with the two outer toothed rings, the inner toothed ring meshing with the toothed shaft on the side close to the motor, and a tapping unit located on the output shaft of the motor. After the main body of the pickling machine is started, it drives the material trough to rotate, which in turn drives the outer sleeve to rotate. The inner sleeve remains stationary during the rotation of the material trough. While the outer sleeve rotates, it drives the gear shaft to revolve around the inner sleeve. When the inner gear ring rotates relative to the corresponding gear shaft, it drives the gear shaft to rotate. The two gear shafts rotate synchronously and drive the two sleeves to rotate simultaneously.

[0007] Furthermore, both ends of the gear shaft are provided with gears, and the two gear shafts mesh with each other. The gear shaft closer to the motor meshes with both the inner gear ring and the corresponding outer gear ring.

[0008] Furthermore, the outer sleeve has symmetrically formed annular grooves in the middle, and the inner wall of the annular grooves is rotatably connected to the collar.

[0009] Furthermore, the outer diameter of the collar is the same as that of the outer sleeve, and the two gear shafts rotate in opposite directions due to their meshing. Therefore, the two collars rotate synchronously in opposite directions.

[0010] Furthermore, the striking unit includes a rotating shaft mounted on the motor output shaft, two cams linearly positioned at the middle of the output and the end furthest from the motor, four limiting sleeves symmetrically positioned at both ends of the outer sleeve, a sliding sleeve fitted onto the outside of the limiting sleeve, a sealing ring positioned at the bottom of the sliding sleeve, a tension spring positioned at the top of the limiting sleeve, the top and bottom ends of the tension spring being fixedly connected to the sliding sleeve and the limiting sleeve respectively, four top rods symmetrically positioned at the bottom of the sliding sleeve on the outer sleeve, and telescopic grooves symmetrically opened at both ends of the inner sleeve.

[0011] Furthermore, the sliding sleeve is tubular in shape, and several short arms are provided on the outer side of the sliding sleeve.

[0012] Furthermore, the inner ring array of the telescopic groove is provided with several short rods, and the two sides of the telescopic groove are connected to each other by several short rods.

[0013] Furthermore, a pressure plate is provided at the top of the top rod, and the bottom end of the short rod is a flat cone shape.

[0014] Another objective of this invention is to provide a pickling method for agricultural and sideline food processing, which aims to improve food production efficiency and pickling effect by using a pickling machine to pickle ingredients.

[0015] To achieve the above objectives, the present invention provides the following technical solution: a pickling method for agricultural and sideline food processing, comprising the following steps: First, start the device. The material trough and outer sleeve rotate, while the inner sleeve remains stationary. The inner toothed ring and toothed shaft move relative to each other, and the drive ring drives the stirring rod to start running. Continuing, the stirring rod undergoes a compound motion, rotating on its own axis while revolving around the outer sleeve, thus thoroughly mixing the marinade without any dead angles. Finally, the rotating cam pushes the push rod to extend and press against the sliding sleeve, quickly pounding the meat. This action breaks the meat fibers, while the tension spring is responsible for driving the push rod to retract and return to its original position.

[0016] Furthermore, the stirring and patting work together until the marinating is complete. This dual action ensures that the marinade is mixed evenly and penetrates quickly. Finally, the device is turned off and the finished product is removed.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the auxiliary mechanism, the ingredients are processed by a combination of tumbling and stirring. During operation, the ingredients are continuously turned and mixed, allowing the external marinade to coat every surface and penetrate into the interior. This movement allows the liquid seasoning to break free from sedimentation and achieve uniform contact and exchange with the solid ingredients. At the same time, the mechanism generates vibration and patting action, which is transmitted to the meat tissue, creating intermittent stimulation to the muscle fibers. Under continuous micro-stress, the fiber structure becomes looser, improving its ability to retain moisture. The squeezing from tumbling and the impact from vibration work together to promote the penetration of flavor substances and change the physical state of the meat. The marinade circulates in a dynamic environment, penetrating deep into the muscle fibers, thus adjusting the firmness of the meat and resulting in a soft texture after cooking. The entire process allows the ingredients to absorb the flavor more fully and the meat to become more tender.

[0018] 2. Through the set pounding unit, the meat is impacted by the reciprocating movement of the sliding sleeve. The sliding sleeve contacts the surface of the meat during the movement, transferring kinetic energy to the internal tissue. This impact acts on the muscle fibers, causing changes in their structure. Under continuous external force, the fibers gradually loosen and break, and the originally tight connection is dispersed. This effect does not rely on chemical additives, but changes the meat quality through physical means. The breaking of fibers expands the water-holding space of the muscle, and the juices can be distributed more evenly in the tissue. The toughness of the meat is thus adjusted, and the resistance during chewing is reduced. The whole process makes the meat more tender while maintaining its original flavor.

[0019] 3. By using the inner and outer sleeves, the energy generated when the material tank rotates is used to drive the movement of the stirring rod. When the material tank starts to operate, its rotational force is transmitted to the stirring system through the interaction between the sleeves. Driven by energy, the stirring rod continuously tumbles the ingredients in the tank, increasing the contact area between the ingredients and the marinating liquid. The marinating liquid, which originally sank, forms a circulating flow during stirring, penetrating the surface of the ingredients and seeping into the interior. This design allows the energy of the rotating material tank to perform two tasks simultaneously, reducing additional energy consumption and allowing the ingredients to absorb flavor evenly in a dynamic environment. The marinating time is shortened, energy is utilized within the system, and the overall power consumption of the equipment is kept at a low level. This structural design achieves a balance between marinating efficiency and energy saving. Attached Figure Description

Detailed Implementation

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Example 1, referring to Figures 1-11 This is the first embodiment of the present invention, providing a pickling device for agricultural and sideline food processing, including a pickling machine body 1, a material trough 2 rotatably connected to the inner side of the pickling machine body 1, and an auxiliary mechanism 3; the auxiliary mechanism 3 includes a motor 31 fixedly connected to the side of the pickling machine body 1 away from the material trough 2, an outer sleeve 32 fixedly connected to the inner wall of the material trough 2 away from the motor 31, an inner sleeve 33 fixedly connected to the side of the pickling machine body 1 near the motor 31, a collar 34 symmetrically rotatably connected to the middle of the outer sleeve 32, four annular array stirring rods 35 fixedly connected to the outer side of the collar 34, an outer toothed ring 36 fixedly connected to the inner side of the collar 34, and a ring fixedly connected to the inner sleeve 33 near the motor 31. The inner gear ring 37 is obliquely and symmetrically connected to the gear shaft 38 inside the outer sleeve 32. The ends of the two gear shafts 38 that are far apart from each other are respectively engaged with the two outer gear rings 36. The inner gear ring 37 is engaged with the gear shaft 38 on the side near the motor 31, and there is also a beating unit mounted on the output shaft of the motor 31. After the main body 1 of the pickling machine is started, it drives the material tank 2 to rotate. The material tank 2 drives the outer sleeve 32 to rotate. The inner sleeve 33 remains stationary during the rotation of the material tank 2. While the outer sleeve 32 rotates, it drives the gear shaft 38 to revolve around the inner sleeve 33. When the inner gear ring 37 rotates relative to the corresponding gear shaft 38, it drives the gear shaft 38 to rotate. The two gear shafts 38 rotate synchronously and drive the two collars 34 to rotate simultaneously.

[0024] Specifically, after the main body 1 of the marinating machine is started, it drives the material tank 2 to rotate. At the same time, the rotation of the material tank 2 drives the outer sleeve 32 to rotate together. During the rotation, the outer sleeve 32 rotates relative to the inner sleeve 33. At the same time, the outer sleeve 32 drives the gear shaft 38 to rotate around the inner sleeve 33. The gear shaft 38, which meshes with the inner gear ring 37, rotates around the inner sleeve 33 and rotates on its own axis under the action of the inner gear ring 37. The two shafts mesh with each other and therefore rotate synchronously in opposite directions. At the same time, the rotation of the two gear shafts 38 drives the corresponding outer gear ring 36 to rotate. The outer gear ring 36 drives the collar 34 connected to it to rotate. Since the collar 34 is constrained by the outer sleeve 32, it can only rotate in place. At the same time, the collar 34 drives the stirring rod 35 connected to it to rotate. The stirring rod 35 stirs the ingredients when it rotates to prevent them from clumping together. Since the two collars 34 are driven by different gear shafts 38, the rotation directions of the two collars 34 are opposite.

[0025] Reference Figures 5-7 Both ends of the gear shaft 38 are equipped with gears, and the two gear shafts 38 mesh with each other. The gear shaft 38 closer to the motor 31 meshes with both the inner gear ring 37 and the corresponding outer gear ring 36.

[0026] Specifically, the two gear shafts 38 mesh with each other at their close ends to achieve synchronous rotation, and the two gear shafts 38 mesh with the corresponding external gear rings 36 at their far ends to make the two external gear rings 36 rotate synchronously in opposite directions.

[0027] Reference Figure 4 The outer sleeve 32 has symmetrically formed annular grooves in the middle, and the inner wall of the annular grooves is rotatably connected to the collar 34.

[0028] Specifically, the outer sleeve 32 is connected to the collar 34 through the annular groove, and constrains the motion freedom of the collar 34, so that the collar 34 can only rotate around its own axis after being driven by the outer toothed ring 36.

[0029] Reference Figures 3-7 The outer diameter of the collar 34 is the same as that of the outer sleeve 32. Since the two gear shafts 38 mesh with each other and rotate in opposite directions, the two collars 34 rotate synchronously in opposite directions.

[0030] Specifically, the outer diameter of the collar 34 is the same as that of the outer sleeve 32 to avoid dead angles caused by the difference in height between different outer diameters, which could cause food to get stuck. Power is transmitted through two gear shafts 38, so that the stirring rods 35 on different collars 34 can rotate synchronously while rotating in opposite directions.

[0031] Example 2, refer to Figures 1-11This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the striking unit includes a rotating shaft 39 fixedly connected to the output shaft of the motor 31, two cams 310 fixedly connected in a straight line to the middle of the output and the end away from the motor 31, four limiting sleeves 311 symmetrically fixedly connected to both ends of the outer sleeve 32, a sliding sleeve 312 sleeved on the outside of the limiting sleeve 311, a sealing ring 313 fixedly connected to the bottom of the sliding sleeve 312, a tension spring 314 fixedly connected to the top of the limiting sleeve 311, the top and bottom ends of the tension spring 314 being fixedly connected to the sliding sleeve 312 and the limiting sleeve 311 respectively, four push rods 315 symmetrically fixedly connected to the outer sleeve 32 at the bottom of the sliding sleeve 312, and telescopic grooves 316 symmetrically opened at both ends of the inner sleeve 33.

[0032] Specifically, after the motor 31 starts, it drives the rotating shaft 39 to rotate. Simultaneously, the rotating shaft 39 drives the two cams 310 to rotate. As the cams 310 rotate, they press against the push rod 315. When the distal end of the cam 310 contacts the push rod 315, the push rod 315 moves away from the cam 310. Simultaneously, the push rod 315 pushes the sliding sleeve 312 to move in the same direction. The movement of the sliding sleeve 312 simultaneously causes the tension spring 314 to store force. Because the sliding sleeve 312 is constrained by the limiting sleeve 311, it can only reciprocate along its own axis. Simultaneously, the movement of the sliding sleeve 312 drives the sealing ring 313 to move. The sealing ring 313 ensures that the sliding sleeve 312 is in contact with the limiting sleeve. Regarding the sealing between sleeves 311, when cam 310 rotates to the proximal end facing push rod 315, the sliding sleeve 312 pushes the pull rod towards cam 310 under the action of tension spring 314, so that the end of push rod 315 near the rotating shaft 39 keeps in contact with cam 310. When the outer sleeve 32 rotates, it will drive push rod 315 to rotate together. After push rod 315 rotates a certain angle, the inclined surface near cam 310 is squeezed by the short rod of telescopic groove 316 and moves away from cam 310. After push rod 315 rotates a certain distance, it releases contact with the short rod. At this time, push rod 315 will reset under the action of tension spring 314 and sliding sleeve 312 and continue to abut against the cam.

[0033] Reference Figures 8-10 The sliding sleeve 312 is tubular in shape, and several short arms are provided on the outer side of the sliding sleeve 312.

[0034] Specifically, the outer wall of the sliding sleeve 312 can prevent abrasion of the food, and the short arm moves with the sliding sleeve 312 to vibrate the meat it comes into contact with, causing the meat fibers to break.

[0035] Reference Figures 6-9 The telescopic groove 316 has a ring array of short rods inside, and the two sides of the telescopic groove 316 are connected to each other by the short rods.

[0036] Specifically, after the inner sleeve 33 has the expansion groove 316, it must be connected by a short rod to avoid being divided into unconnected parts.

[0037] Reference Figures 8-11 The top of the top rod 315 is equipped with a pressure plate, and the bottom end of the short rod is a flat cone shape.

[0038] Specifically, the top rod 315 pushes the sliding sleeve 312 through the pressure plate, and the short rod is squeezed by the tapered inclined surface at the bottom, so that it can move by deflecting the direction of the force. The rest of the structure is the same as that of Embodiment 1.

[0039] Based on embodiments 1-2, the working principle of this invention is as follows: When marinating ingredients, the ingredients and auxiliary materials are placed in the material tank 2 and the material tank 2 is sealed. Then, the material tank 2 is rotated by starting the main body 1 of the marinating machine. While the material tank 2 is rotating, the ingredients inside are tumbled. During this process, the outer sleeve 32 and the inner sleeve 33 rotate relative to each other using the power of the rotation of the material tank 2, thereby driving the stirring rod 35 to rotate. The stirring rod 35 stirs the ingredients while they are being tumbled, preventing them from clumping together and making the marinating more uniform. When marinating meat, in order to make the meat more tender, the motor 31 can be started. The motor 31 drives the top rod 315 to extend through the rotating shaft 39 and the cam 310. The top rod 315 pushes out the sliding sleeve 312, and the sliding sleeve 312 can be reset under the action of the tension spring 314. While the sliding sleeve 312 is in contact with the meat, it transmits its own linear vibration to the meat, causing the meat fibers to break, making it more tender and improving the taste.

[0040] Example 3, referring to Figures 1-11 The third embodiment of the present invention provides: a pickling method for agricultural and sideline food processing, comprising the following steps: S1, First, start the device. The material tank 2 and the outer sleeve 32 rotate, while the inner sleeve 33 remains stationary. The inner toothed ring 37 and the toothed shaft 38 move relative to each other. The driving ring 34 drives the stirring rod 35 to start running. The outer sleeve 32 uses the power of the material tank 2 to rotate synchronously with the material tank 2 and generates relative rotation with the stationary inner sleeve 33.

[0041] S2, continue, the stirring rod 35 performs compound motion, while rotating with the outer sleeve 32, it rotates by the gear shaft 38, and mixes the marinade without dead angles. The slip ring drives the stirring rod 35 to stir the ingredients and assist in marinating.

[0042] S3. Finally, the cam 310 rotates to push the push rod 315 out to press the sliding sleeve 312 and quickly pat the meat. This action breaks the meat fibers. The tension spring 314 is responsible for driving the push rod 315 to retract back to its original position. The cam 310 pushes the push rod 315 and the sliding sleeve 312 out by rotating rapidly. It works with the tension spring 314 to make the sliding sleeve 312 vibrate, thereby making the meat more tender.

[0043] S4, the stirring and patting work together until the marinating is complete. The dual action ensures that the marinade is mixed evenly and penetrates quickly. Finally, the device is turned off and the finished product is taken out. The marinated food must be aseptically stored or used as soon as possible.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
