Description

Technical Field

[0001] This invention relates to the field of processing marinated soft-boiled eggs, specifically a system and method for controlling the microorganisms and softness of marinated soft-boiled eggs. Background Technology

[0002] Soft-boiled eggs have a relatively short shelf life, mainly due to the degree of softness and the influence of microorganisms on the egg. (The larger the soft spot, the larger the proportion of raw yolk, the higher the probability of yolk hydration and the higher the probability of yolk turning green when it meets the thicker side of the albumen. Both of these conditions reduce the sensory quality of the soft-boiled egg, and in severe cases, it is considered spoilage. Microorganisms can cause product spoilage, bloating, and other quality problems.) Therefore, to extend the shelf life of soft-boiled eggs, the production process must be carefully controlled, starting from the raw eggs, steaming, and peeling. This is especially true for marinated soft-boiled eggs, which require soaking in low-temperature conditions to absorb the flavor. Therefore, the soaking time and method must also be controlled, as the longer the soaking time, the easier it is for microorganisms to grow in the marinade, affecting the egg's shelf life. Summary of the Invention

[0003] Therefore, in order to overcome the above-mentioned shortcomings, the present invention provides a processing system and method for braised soft-boiled eggs. The present invention improves and controls key nodes such as raw eggs, steaming, peeling and soaking, thereby controlling the microorganisms and softness of the braised soft-boiled eggs, and achieving wide temperature range preservation of braised soft-boiled eggs.

[0035] The feeding roller, the smooth rod, and the peeling roller are parallel to each other, and together they form a peeling channel for the movement of poultry eggs.

[0038] Optionally, the shelling and sorting module further includes a rolling device, which is disposed between the grading device and the shelling device. The rolling device is disposed corresponding to the grading roller group to receive poultry eggs discharged from the grading gap.

[0039] The rolling device includes:

[0040] The feeding conveyor is connected to the grading device;

[0041] Roller conveyor, wherein the roller conveyor is positioned above the feeding conveyor;

[0042] A rolling gap is formed between the rolling conveyor and the feeding conveyor, and the rolling gap increases sequentially from the rolling device at the starting end to the rolling device at the tail end.

[0043] The rolling device at the starting end is a rolling device that receives poultry eggs discharged from the grading roller group at the starting end, and the rolling device at the tail end is a rolling device that receives poultry eggs discharged from the grading roller group at the tail end.

[0044] Optionally, the selection module further includes a defoaming device, which is connected to the shelling device; the defoaming device includes:

[0045] Defoaming box, wherein the defoaming box contains a limited volume of disinfectant; and

[0046] The third lifting conveyor line has its lower part installed inside the defoaming box and its upper part extending out of the defoaming box from the opening.

[0047] Optionally, the soaking and flavoring module includes a soaking tank in which an ultrasonic module is installed.

[0048] On the other hand, the present invention provides a method for processing braised soft-boiled eggs, which is achieved through the processing system for braised soft-boiled eggs, and the method includes the following steps:

[0049] After undergoing light inspection, the raw eggs are screened and cleaned through the raw material quality control module;

[0050] The cleaned eggs are placed into the steaming and centering module, where the eggs are rolled to keep the yolk in the center during steaming.

[0051] After steaming and setting, the temperature of the egg yolks is quickly sampled by an inspection agency. The steaming time and temperature are adjusted based on the yolk temperature to control the soft-boiled state.

[0052] The cooked eggs are sent to the shelling and sorting module for grading, sorting and shelling.

[0053] The peeled eggs are placed into a soaking and flavoring module for ultrasonic soaking and flavoring. The brine in the soaking and flavoring module contains a compound enzyme preparation.

[0054] The present invention has the following advantages:

[0055] This invention improves and controls key processes such as raw egg preparation, steaming, peeling, and soaking, thereby controlling the microorganisms and softness of the marinated soft-boiled eggs and achieving wide-temperature-range preservation of the marinated soft-boiled eggs.

[0056] The raw material quality control module performs flotation and cleaning on the raw eggs. The flotation screens out unqualified eggs, and the cleaning removes foreign matter from the surface of the eggs. The cleaning solution can be 50ppm sodium hypochlorite to reduce microorganisms on the eggshell surface.

[0057] The steaming and centering module uses steam to cook the eggs, enabling rapid temperature control. During steaming, the eggs are gently rolled to prevent the yolk from sinking after standing still, thus centering the yolk in the center of the egg after steaming, improving the quality of the soft-boiled egg. This also prevents the yolk from being too close to the shell during peeling, which can cause the egg white to break and leak out. The module also includes a sampling mechanism for quick egg inspection. This mechanism allows for rapid egg positioning, enabling staff to accurately locate the yolk and measure its temperature. The yolk temperature measurement allows for the calculation of the soft-boil state, facilitating better control of the steaming temperature and time (the time is determined by the size of the conveyor belt).

[0058] The shelling and sorting module uses a conveyor roller assembly to move eggs towards a grading roller assembly. After being sorted and graded by multiple grading roller assemblies, the eggs are sent to different shelling chambers according to their size. Shelling components with matching gaps then peel the eggs, allowing for simultaneous shelling of eggs of different sizes, improving efficiency and avoiding incomplete shelling or incomplete products. (Traditional shelling mechanisms often result in incomplete shelling and cracking due to inconsistent egg sizes. Cracks can lead to runny yolks leaking out, which can adhere to other eggs, affecting their quality. Furthermore, leaked yolks can promote microbial growth in other eggs, impacting their shelf life.)

[0059] The soaking and flavoring module uses ultrasonic-assisted soaking to achieve rapid flavoring, shorten the soaking time, and avoid the decline in egg quality caused by prolonged soaking, which can also easily lead to the growth of microorganisms in soft-boiled eggs. At the same time, a compound enzyme preparation is added to the brine to inhibit the growth of microorganisms. Attached Figure Description

[0100] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0101] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0102] As described in the background section, soft-boiled eggs have a relatively short shelf life, mainly due to the softness of the yolk and the influence of microorganisms on the egg. Therefore, in order to extend the shelf life of soft-boiled eggs, the production process must be controlled at least from the raw egg, steaming, and peeling processes. In particular, for marinated soft-boiled eggs, which need to be soaked in low-temperature conditions to absorb the flavor, the soaking time and method also need to be controlled. The longer the soaking time, the easier it is for microorganisms to grow in the marinade, affecting the shelf life of the egg.

[0103] For the reasons mentioned above, this embodiment is as follows: Figure 1 As shown, a processing system for braised soft-boiled eggs is provided, comprising at least:

[0104] The raw material quality control module is used to screen and clean the raw eggs;

[0105] The steaming and centering module is used to steam and center eggs that have completed quality control. Steaming and centering means that the yolk of the egg remains in the center area of ​​the egg during steaming and cooking.

[0106] The shell-peeling and sorting module is used to peel and sort eggs after they have been steamed and set; and

[0107] The soaking and flavoring module is used to soak and flavor the qualified eggs that have been peeled and selected.

[0108] The raw material quality control module includes a screening device and a cleaning device.

[0109] The above-mentioned technical features enable improvements and controls at key stages such as raw egg production, steaming, peeling, and soaking, thereby controlling the microorganisms and softness of the marinated soft-boiled eggs and achieving wide-temperature-range preservation (the wide temperature range can be 0-30℃).

[0110] In one embodiment, such as Figures 2-7 As shown, the screening device includes:

[0111] Tray 110, on which a plurality of isolation slots 111 for placing raw eggs are formed;

[0112] Screening pool 120 is used to screen raw eggs immersed in screening pool 120;

[0113] The transport mechanism 130 is installed on the screening pool 120 and is used to immerse the pallet 110 into the screening pool 120.

[0114] Existing screening equipment, using light, is insufficient to remove raw eggs that have been stored for too long, resulting in some stale eggs remaining after screening. In this solution, because the internal air cells of raw eggs expand after prolonged storage, leading to a decrease in egg density, the transport mechanism 130 immerses the tray 110 and the raw eggs into the screening pool 120. Raw eggs with a density lower than that of the liquid inside the screening pool 120 will float to the surface and be removed, thus solving the problem of stale eggs remaining after screening.

[0115] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the specific structure of the fixed transport mechanism 130, one feasible solution is as follows: the transport mechanism 130 includes a feeding conveyor belt 131 and a discharging conveyor belt 132 for transporting the pallet 110. The pallet 110 is equipped with a first roller 112 and a second roller 113, and the diameter of the first roller 112 is larger than that of the second roller 113. The screening pool 120 has a first slide rail 121 that cooperates with the first roller 112 and a second slide rail 122 that cooperates with the second roller 113. Both the first slide rail 121 and the second slide rail 122 extend downward at an incline to the lower part of the screening pool 120. When this solution is adopted, the pallet 110 is pushed towards the screening pool 120 by the feeding conveyor belt 131. The first roller 112 can cross the second slide rail 122 and enter the first slide rail 121, while the second roller 113 enters the second slide rail 122, thereby causing the pallet 110 to be tilted and immersed in the screening pool 120.

[0116] like Figure 5 As shown, in order to make the tray 110 float after screening, one feasible solution is: a horizontal slide 123 is formed at the bottom of the screening pool 120, and the transport mechanism 130 also includes a lifting rod 133 installed in the screening pool 120, and the lifting rod 133 is used to drive the tray 110 to float. When this solution is adopted, the lifting rod 133 drives the tray 110 and the screened raw eggs to float together.

[0117] In order to move the tray 110 from the horizontal slide 123 to the lifting rod 133, one feasible solution is to install a first telescopic rod 124 on the screening tank 120 and install a first push plate 125 on the first telescopic rod 124 for pushing the tray 110 towards the lifting rod 133 along the horizontal slide 123. When this solution is adopted, when the first telescopic rod 124 extends, it can push the tray 110 towards the lifting rod 133.

[0118] like Figure 3 and Figure 5 As shown, in order to move the pallet 110 from the lifting rod 133 to the discharge conveyor belt 132, one feasible solution is to install a second telescopic rod 126 on the screening tank 120, and install a second push plate 127 on the second telescopic rod 126 for pushing the pallet 110 towards the discharge conveyor belt 132 along the lifting rod 133. The lifting rod 133 is connected to a lifting shaft 134. When this solution is adopted, when the second telescopic rod 126 extends, it can push the pallet 110 towards the discharge conveyor belt 132.

[0119] like Figure 4 As shown, drainage holes 114 are formed on the isolation tank 111, which facilitates the timely drainage of liquid in the tray 110 when the tray 110 is removed from the screening tank 120.

[0120] To address the issue of stale raw eggs remaining after screening, this solution addresses the problem that prolonged storage of raw eggs leads to the expansion of internal air cells, resulting in a decrease in egg density. A transport mechanism 130 immerses the tray 110 and the raw eggs into a screening pool 120. Raw eggs with a density lower than that of the liquid inside the screening pool 120 float to the surface and are discarded, thus resolving the issue of stale raw eggs remaining after screening.

[0121] To facilitate the smooth immersion of the pallet 110 into the screening tank 120, in this design, the transport mechanism 130 includes a feeding conveyor belt 131 and a discharging conveyor belt 132 for transporting the pallet 110. The pallet 110 is equipped with a first roller 112 and a second roller 113, with the diameter of the first roller 112 being larger than that of the second roller 113. The screening tank 120 has a first slide 121 that cooperates with the first roller 112 and a second slide 122 that cooperates with the second roller 113. Both the first slide 121 and the second slide 122 extend downwards at an incline to the lower part of the screening tank 120. The feeding conveyor belt 131 pushes the pallet 110 toward the screening tank 120, allowing the first roller 112 to pass over the second slide 122 and enter the first slide 121, while the second roller 113 enters the second slide 122, thereby causing the pallet 110 to be immersed in the screening tank 120 at an incline.

[0122] In one embodiment, such as Figures 8-13 The cleaning device includes:

[0123] The cleaning tank 210 has several nozzles 211 installed on its side wall for spraying cleaning fluid.

[0124] Several cleaning trays 220 are spaced apart in the cleaning tank 210, and several limiting rings 221 for placing eggs are rotatably connected to the cleaning trays 220.

[0125] The first brush 230 is installed on the cleaning tray 220 and is used to clean the side walls of eggs;

[0126] The second brush 240 is located below the limiting ring 221 and is used to clean the bottom of the eggs.

[0127] Existing cleaning equipment uses a motor to drive a rotating roller, which in turn rotates the egg. However, the cleaning roller is not very effective at cleaning the top and bottom of the egg. In this solution, the egg is placed on a limiting ring 221, and a nozzle 211 sprays cleaning liquid onto the egg. When the first brush 230 rotates, it can clean the side wall of the egg and cause the egg to rotate the limiting ring 221. When the egg rotates, the bottom of the egg can be cleaned by the action of the second brush 240. The wastewater generated during cleaning is discharged through a drain pipe 213 located at the bottom of the cleaning tank 210, thus solving the problem of poor cleaning effect.

[0128] like Figure 9 and Figure 10 As shown, this solution does not exclusively limit the driving structure of the first brush 230. One feasible solution is: the first brush 230 is connected to a rotating shaft 231 and a connecting block 232 is formed on the rotating shaft 231. Several motors 233 for independently driving the rotating shaft 231 are installed at the bottom of the cleaning tank 210. When this solution is adopted, the corresponding rotating shaft 231 is independently driven by the motor 233, thereby causing the two adjacent first brushes 230 to generate a differential speed, so as to make the egg and the limiting ring 221 rotate.

[0129] To facilitate the connection of the connecting blocks 232, a feasible solution is to install a positioning rod 212 inside the cleaning tank 210 and form a positioning sleeve 222 on the cleaning tray 220 that cooperates with the positioning rod 212. When this solution is adopted, the connecting blocks 232 can be aligned with each other by the cooperation of the positioning rod 212 and the positioning sleeve 222, which facilitates the connection of the connecting blocks 232.

[0130] like Figure 12 As shown, this solution does not limit the specific structure of the connecting block 232. In this embodiment, the connecting block 232 has a toothed structure 2321 and a grooved structure 2322 that meshes with the toothed structure 2321. When this solution is adopted, pressing the cleaning tray 220 will cause the toothed structure 2321 to slide into the grooved structure 2322 and mesh with each other.

[0131] like Figure 11 As shown, in order to fix the distance between two adjacent cleaning trays 220, one feasible solution is: the positioning sleeve 222 extends downward from the cleaning tray 220 and the lower end face of the positioning sleeve 222 contacts the bottom of the cleaning tank 210 or another cleaning tray 220. When this solution is adopted, the distance between two adjacent cleaning trays 220 can be fixed by the positioning sleeve 222.

[0132] To improve the cleaning effect, one feasible solution is that the second brush 240 is a double-sided brush and is also used to clean the top of the egg. When this solution is adopted, the side wall, top and bottom of the egg can be cleaned by the first brush 230 which contacts the side wall of the egg and the second brush 240 which contacts the top or bottom of the egg, thus improving the cleaning effect.

[0133] To further improve the cleaning effect, one feasible solution is to form grooves on both brush surfaces of the second brush 240. When this solution is adopted, the top and bottom of the egg can easily come into contact with the corresponding second brush 240, thereby further improving the cleaning effect.

[0134] like Figure 13 As shown, preferably, a top cover 250 is installed on the uppermost washing tray 220, and a positioning sleeve 222 and a second brush 240 are provided on the top cover 250. When this solution is adopted, the top of the uppermost layer of eggs can be cleaned.

[0135] To address the issue of poor cleaning performance, this solution involves placing an egg on a limiting ring 221 and spraying cleaning fluid onto the egg using a nozzle 211. When the first brush 230 rotates, it cleans the sidewalls of the egg and causes the limiting ring 221 to rotate. As the egg rotates, the second brush 240 cleans the bottom of the egg, thus resolving the problem of poor cleaning performance.

[0136] To facilitate the rotation of the egg and the limiting ring 221, since the first brush 230 is connected to the rotating shaft 231 and the rotating shaft 231 has a connecting block 232, the bottom of the cleaning tank 210 is equipped with several motors 233 for independently driving the rotating shaft 231. The motors 233 independently drive the corresponding rotating shaft 231, thereby causing the two adjacent first brushes 230 to have a differential speed, so as to facilitate the rotation of the egg and the limiting ring 221.

[0137] To improve the cleaning effect of eggs, since the second brush 240 is a double-sided brush and is also used to clean the top of the egg, the sidewall, top and bottom of the egg can be cleaned by the first brush 230 which contacts the sidewall of the egg and the second brush 240 which contacts the top or bottom of the egg, thus improving the cleaning effect.

[0138] In one embodiment, such as Figures 14-23 As shown, the cooking and centering module includes:

[0139] It includes a steaming tank 310, which is equipped with steam that sprays upwards and a feeding mechanism 350 for conveying eggs.

[0140] The transmission chamber 320, located above the cooking tank 310, rotates the eggs placed on the feeding mechanism 350 and simultaneously discharges steam.

[0141] The sampling inspection mechanism 340 is installed above the cooking tank 310 outside the discharge end of the feeding mechanism 350, which can be raised and lowered to remove the discharged eggs one by one and test the internal temperature.

[0142] From the appendix Figure 14 and attached Figure 15 It can be seen that a drive motor is also provided at the outer end of the cooking tank 310 and the transmission chamber 320 to drive the feeding mechanism 350 and the transmission mechanism inside the transmission chamber 320.

[0143] A feed ramp 312 is provided at the top of one end of the cooking tank 310. On both sides of the feed ramp 312, pads 311 are fixed to the top of the cooking tank 310. Threaded rods 313 are provided on the pads 311. A discharge ramp 314 is provided at the top of the other end of the cooking tank 310. A bracket 315 is provided on the discharge ramp 314 to facilitate the installation of the sampling inspection mechanism 340.

[0144] The inclination direction of the feed ramp 312 and the discharge ramp 314 is consistent and adapted to the feeding direction of the feeding mechanism 350. A steam inlet 316 is provided on the side wall and / or bottom of the cooking tank 310 (this steam inlet is a conventional air intake method, which will not be described in detail here).

[0145] To prevent eggs from piling up and rolling onto the feeding mechanism 350, causing multiple eggs to be cooked in one steaming position, resulting in the eggs not being able to rotate, or even colliding and breaking, a feasible solution is provided. Specifically, a uniform feeding mechanism 330 is provided above the feeding ramp 312. The uniform feeding mechanism 330 ensures that the eggs roll evenly onto the feeding mechanism 350. The uniform feeding mechanism 330 is a feeding baffle 331, with both ends of the feeding baffle 331 inserted into the threaded rod 313. The middle part of the feeding baffle 331 corresponds to the feeding ramp 312. An adjusting member 332 is also threadedly connected to the threaded rod 313. The feeding baffle 331 passes through the threaded rod 313 and is placed on the adjusting member 332.

[0146] The adjusting component 332 is an adjusting nut, which is threaded onto the threaded rod 313, thereby achieving the gap between the feed baffle 331 and the feed inclined plate 312, so that the eggs can roll through evenly. The bottom of the feed baffle 331 can be evenly provided with multiple slots to facilitate the passage of eggs.

[0147] To avoid burns caused by manually removing eggs for temperature testing after steaming, a feasible solution is provided here. Specifically, the sampling mechanism 340 includes a sampling frame 342, and the sampling frame 342 has a through opening on the side corresponding to the feeding mechanism 350.

[0148] The linear telescopic device 341 is mounted on the bracket 315 and keeps the telescopic end passing through the bracket 315 vertically downward and fixed to the top of the sampling frame 342;

[0149] The first baffle 343 has one end rotatably mounted on the top of the opening of the sampling frame 342 near the feeding mechanism 350, and the other end is set inside the sampling frame 342 and tilted downward.

[0150] The second baffle 344 is rotatably installed at one end on the bottom of the opening of the sampling frame 342 near the feeding mechanism 350, and the other end is provided with traction ropes 347 on both sides to keep the second baffle 344 tilted on the outer surface of the sampling frame 342.

[0151] Several guide wheels 345 are set at the top four corners of the sampling frame 342;

[0152] The lifting plate 346 is set on the outside of the opening end of the sampling frame 342 away from the feeding mechanism 350 and is raised and lowered by the linear telescopic device 341.

[0153] The temperature measuring rod 348 has one end that passes through the side of the sampling frame 342 and is inserted into the inside of the egg in the sampling frame 342 to measure the temperature, and the other end that extends to the outside of the sampling frame 342.

[0154] The elastic element 349 is sleeved on the outside of the temperature measuring rod 348 and its two ends are respectively connected to the outside of the sampling frame 342 and the end of the temperature measuring rod 348;

[0155] One end of the traction rope 347 is fixed to the second baffle 344, and the other end passes through the guide wheel 345 and is connected to the lifting plate 346. The lifting plate 346 drives the second baffle 344 to rotate.

[0156] Furthermore, the linear telescopic device can be configured as an electric telescopic rod or cylinder that is easy to control automatically. When the linear telescopic device on the bracket is lowered, it will drive the sampling frame 342 to descend onto the discharge inclined plate 314 and connect with the discharge end of the feeding mechanism 350.

[0157] When the linear telescopic device 341 on the sampling frame 342 is raised, it drives the lifting plate 346 to rise. At this time, the traction rope 347 is released, and the second baffle 344 loses the tension of the traction rope 347. Under the action of gravity, it will flip outward, that is, open the opening of the sampling frame 342, so that the eggs can roll from the discharge end of the feeding mechanism 350 into the sampling frame 342 and be initially fixed by the obstruction of the first baffle 343.

[0158] When an egg rolls into the sampling frame 342, the linear telescopic device 341 on the sampling frame 342 descends, causing the lifting plate 346 to descend as well. At this time, the traction rope 347 is pulled to move, which in turn causes the second baffle 344 to flip upward, closing the opening of the sampling frame 342 and preventing subsequent eggs from rolling into it. This also secures the eggs again. Then, the linear telescopic device on the support retracts, lifting the entire sampling frame 342 and the eggs upward, thus not affecting the transport of subsequent eggs. Finally, the worker presses the temperature measuring rod 348 towards the sampling frame 342, squeezing the elastic element 349 to keep the sharp end of the temperature measuring rod 348 inserted into the egg and in contact with the yolk, thus achieving temperature measurement (as shown in the attached image). Figure 21 As can be seen, the outer end of the temperature measuring rod is a pressing part, and the other end is a sharp piercing part. After the temperature measurement is completed, release the temperature measuring rod 348, and the temperature measuring rod 348 will separate from the egg under the elastic action of the elastic element 349.

[0159] Specifically, a torsion spring is provided at the hinge point between the first baffle 343 and the sampling frame 342 (this installation method can refer to the existing clamp structure), and the torsion spring keeps the first baffle 343 tilted downward inside the sampling frame 342.

[0160] Furthermore, the torsion spring at the hinge point of the first baffle 343 is designed to block the eggs and prevent them from rolling directly out through the opening of the sampling frame 342. It also makes it easier for staff to remove the eggs after the sampling is completed.

[0161] To prevent eggs from becoming stationary during the steaming process, which could affect the steaming and subsequent yolk setting, a feasible solution is provided. Specifically, the transmission chamber 320 includes a frame 321 and several rotating rods 323 mounted on the frame 321. The frame 321 is placed above the steaming tank 310. The rotating rods 323 span across the steaming tank 310 and are mounted on the frame 321 at the same height. Drive wheels 324 are provided at both ends of the rotating rods 323 inside the frame 321, and transmission wheels 325 are provided on the rotating rods 323 outside the frame 321. Transmission belts 326 are provided at the outer ends of the transmission wheels 325 on the rotating rods 323, driving the rotating rods 323 to rotate synchronously and in the same direction. An exhaust pipe 322 is also provided at the top center of the frame 321.

[0162] To prevent eggs from becoming stuck during the conveying and cooking process, which would affect the cooking process and the subsequent setting of the yolks, a feasible solution is provided here. Specifically, the feeding mechanism 350 includes two drive rods 351, which are arranged in parallel within the cooking tank 310 and are rotatably connected.

[0163] Multiple sprockets 352 are mounted on both ends of two drive rods 351 and correspond to each other;

[0164] Multiple chains 353 are tensioned on sprockets 352 of two drive rods 351 respectively;

[0165] Mounting plate 354 is mounted on the link of chain 353;

[0166] The support rod 356 passes through the mounting plate 354 of multiple chains 353 and is connected to the mounting plate 354 via a rotating connector 355;

[0167] Driven wheel 358 is mounted on both ends of support rod 356 to maintain contact with drive wheel 324 inside transmission chamber 320;

[0168] The sleeve 357 is mounted on the support rod 356 between the chains 353.

[0169] Specifically, the outer part of the sleeve 357 is formed by a combination of several tubes that are large at both ends and small in the middle, and the driving wheel 324 or the driven wheel 358 is a friction wheel.

[0170] Furthermore, the shape of the sleeve 357 is designed to facilitate fixing the egg between the two support rods 356. The driving wheel 324 or the driven wheel 358 is designed as a friction wheel so that when the driving wheel 324 and the driven wheel 358 are in contact, the driving wheel 324 can drive the driven wheel 358 to rotate, thereby achieving friction transmission. This facilitates the rotation of the egg on the support rod 356. Compared with gear transmission, this transmission method can reduce vibration and prevent the chain from shaking, which would cause the egg to roll randomly.

[0171] In use, the cooking equipment introduces high-temperature steam into the cooking tank 310 through the steam inlet 316. Simultaneously, the drive motor drives the feeding mechanism 350 and the transmission wheel 325 and transmission belt 326 inside the transmission chamber 320. The height of the feed baffle 331 is adjusted according to the size of the eggs through the adjusting component 332. Then, the eggs are placed on the feed ramp 312 for feeding. Under the action of gravity, the eggs pass through the gap between the feed baffle 331 and the feed ramp 312 and fall onto the sleeve 357 of the adjacent support rod 356. With the transmission of the chain 353, the eggs are driven into the transmission chamber 320 and cooked by the steam at the bottom. During the movement, the driven wheel 358 at the outer end of the support rod 356 that supports the eggs contacts the driving wheel 324 and rotates, thereby driving the eggs to rotate. This ensures that the eggs are heated evenly and that the yolk is fixed in the middle after cooking. Finally, after cooking, the eggs fall onto the discharge ramp 314 for discharge.

[0172] If random inspection is required, when the linear telescopic device 341 on the bracket 315 is lowered, it will drive the inspection frame 342 to descend onto the discharge ramp 314 and connect with the discharge end of the feeding mechanism 350.

[0173] At the same time, the linear telescopic device 341 on the sampling frame 342 is raised, which drives the lifting plate 346 to rise. At this time, the traction rope 347 is released, and the second baffle 344 loses the tension of the traction rope 347. Under the action of gravity, it will flip outward, that is, open the opening of the sampling frame 342, so that the eggs can roll from the discharge end of the feeding mechanism 350 into the sampling frame 342 and be initially fixed by the obstruction of the first baffle 343.

[0174] When an egg rolls into the sampling frame 342, the linear telescopic device 341 on the sampling frame 342 descends, causing the lifting plate 346 to descend as well. At this time, the traction rope 347 is pulled to move, which in turn causes the second baffle 344 to flip upward and close the opening of the sampling frame 342, preventing subsequent eggs from rolling into the sampling frame 342 and also securing the eggs again. Then, the linear telescopic device on the support retracts, lifting the entire sampling frame 342 and the eggs upward, so as not to affect the subsequent egg transport. Finally, the staff presses the temperature measuring rod 348 towards the sampling frame 342, squeezing the elastic element 349 to keep the sharp part of the temperature measuring rod 348 inserted into the egg and in contact with the yolk to measure the temperature. After the temperature measurement is completed, the temperature measuring rod 348 is released, and the temperature measuring rod 348 separates from the egg under the elastic action of the elastic element 349.

[0175] In one embodiment, such as Figure 24-39 As shown, the shelling and sorting module includes a grading device 430 and a shelling device 470;

[0176] The grading device includes a conveying roller group 431 and a grading roller group 432. The conveying roller group drives the movement of poultry eggs. The grading roller group has multiple groups, which are linearly distributed. The grading roller group at the end is connected to the conveying roller group. The discharge gap of the grading roller group increases sequentially from the grading roller group at the starting end to the grading roller group at the tail end. The grading roller group at the starting end is the group connected to the conveying roller group. The grading roller group at the tail end is the grading roller group farthest from the conveying roller group among the multiple grading roller groups. The discharge gap is the gap between adjacent rollers in each group of grading roller groups.

[0177] The shelling device 470 includes a housing 461 and shelling components. The housing 461 has shelling cavities corresponding to the number of the grading roller groups. The shelling components are installed in the shelling cavities. Each shelling cavity has at least one set of shelling components. The shelling gap of the shelling components increases sequentially from the shelling components at the starting end to the shelling components at the tail end. The shelling components at the starting end are shelling components set in the shelling cavity at the starting end. The shelling components at the tail end are shelling components set in the shelling cavity at the tail end. The shelling cavity at the tail end is a shelling cavity connected to the grading roller group at the starting end.

[0178] The peeling component includes:

[0179] Feeding roller 462, the feeding roller is provided with a feeding part that spirals around the outer circumference of the feeding roller;

[0180] The light rod 466 has one end fixedly connected to the side wall of the peeling cavity. The light rod is arranged adjacent to the feeding roller and is located on one side of the lower part of the feeding roller.

[0181] Peeling roller 465, the peeling roller is disposed on the side of the smooth rod away from the feeding roller, and the peeling roller is disposed on the upper side of the smooth rod;

[0182] The feeding roller, the smooth rod, and the peeling roller are parallel to each other, and together they form a peeling channel for the movement of poultry eggs.

[0183] The end of the rod that is not connected to the side wall of the shelling cavity forms an outlet 465 for the discharge of poultry eggs with the side wall of the shelling cavity.

[0184] The peeling gap includes the gap between the feeding roller and the guide rod, the gap between the guide rod and the peeling roller, and the gap between adjacent peeling rollers.

[0185] In this embodiment, the peeling roller and the feeding roller are connected by a power component 463 installed on the side of the housing. The power component drives the peeling roller and the feeding roller to rotate simultaneously. The power component includes a drive device and a transmission component. The transmission component can be a sprocket transmission mechanism, a pulley transmission mechanism or other transmission mechanisms that can realize power transmission between the peeling roller and the feeding roller.

[0186] During operation, the conveyor roller assembly moves the eggs towards the grading roller assembly. When passing the initial grading roller assembly, eggs smaller than the grading gap of the initial grading roller assembly will leak out, while eggs larger than the grading gap of the initial grading roller assembly will move to the adjacent grading roller assembly under the action of the initial grading roller assembly. This process is repeated, and the eggs, which have been divided into multiple sizes, are sent into the corresponding peeling chambers in the peeling device. Since the peeling gap of the peeling component is designed according to the size of the eggs, the peeling component will not cause excessive compression of the eggs, nor will it have too large a gap with the eggs, thus enabling better peeling of the eggshells. The peeled eggshells leak out from the peeling gaps, and the peeled eggs are discharged from the outlet.

[0187] The eggs are driven to the grading roller group by the conveyor roller group. After being sorted and graded by multiple grading roller groups, the eggs are sent to different peeling chambers according to their specifications. The peeling components with matching peeling gaps peel the eggs, thereby achieving simultaneous peeling of eggs of different specifications, improving efficiency and avoiding incomplete peeling or incomplete products.

[0188] In one embodiment, the peeling device further includes:

[0189] Slag discharge port 467, the slag discharge port is set below the polished rod;

[0190] The discharge port 468 is located below the outlet.

[0191] Slag discharge conveyor 464 is provided below slag discharge port 467.

[0192] By setting up slag discharge ports and material discharge ports, eggshells and egg products can be discharged separately, avoiding the mixing of eggshells and egg products and the difficulty in cleaning. The slag discharge is then conveyed to a centralized eggshell collection point for centralized processing. Both the slag discharge ports and material discharge ports are fixed to the bottom of the box. The corresponding peeling chamber in the peeling device can use an inclined distribution channel. By placing the outlet of the distribution channel above the peeling channel, the eggs to be graded are sent to different peeling channels within the same peeling chamber.

[0193] In order to achieve pre-crushing of eggshells before peeling, the peeling and sorting module also includes a shell-knocking device 420, which is connected to the grading device.

[0194] The shell-knocking device includes:

[0195] The shell-knocking conveyor line 422 drives the movement of poultry eggs.

[0196] Power unit 423 drives the shell-knocking conveyor line to move;

[0197] The egg-knocking part 427 is located above the shell-knocking conveyor line and is driven by a power device to move vertically back and forth.

[0198] The power unit drives the shell-knocking conveyor line to move the eggs to the area below the egg-knocking section. At the same time, the egg-knocking section slides vertically down under the action of the power unit, breaking the eggshell. After the eggshell is broken, the shell-peeling device can peel the egg more easily and completely.

[0199] In this embodiment, the shell-knocking device may further include

[0200] A Geneva drive mechanism 425 is connected to the power input section of the shell-striking conveyor line;

[0201] An eccentric wheel linkage transmission mechanism 429 is connected to a power unit. The grooved wheel transmission mechanism is connected to the eccentric wheel linkage transmission mechanism via a belt drive or a sprocket drive mechanism. The egg-knocking part is connected to the eccentric wheel linkage transmission mechanism via a connecting part 426, and the egg-knocking part is fixedly installed on the connecting part.

[0202] The eccentric wheel linkage transmission mechanism is driven by a power source, which in turn drives the egg-knocking section to reciprocate up and down. Simultaneously, the belt drive or sprocket drive mechanism drives the grooved wheel transmission mechanism, causing the egg-knocking conveyor line to move in steps. For example, when the egg-knocking section rises vertically, the egg-knocking conveyor line moves the eggs forward a preset distance; when it descends, the egg-knocking conveyor line stops moving, preventing missed egg-knocking. In this embodiment, the grooved wheel transmission mechanism can be a five-section grooved wheel transmission mechanism, or other multi-section grooved wheel transmission structures can be selected according to actual conditions.

[0203] In this embodiment, the shell-knocking conveyor line includes multiple egg-feeding sections 424, and at least one egg-receiving hole 424A matching the shape of the poultry egg is provided on the surface of the egg-feeding section.

[0204] An egg-holding part 428 is fixed on the egg delivery part. The egg-holding part 428 spans the egg-containing hole and is fixed to the egg delivery part. The egg-holding part is made of flexible material.

[0205] By using the egg-holding hole to limit the position of the eggs, it can prevent the eggs from rolling during the shell-knocking and conveying process. The egg-supporting part provides support for the eggs, preventing them from leaking out of the egg-holding hole.

[0206] In this embodiment, the egg-carrying part described above can be used as follows: Figure 30 The strip shape shown can also be a sheet or a mesh. The material of the egg tray can be a soft and elastic material such as leather or rubber.

[0207] When the egg is being tapped, the egg-holding part can stretch downwards a certain distance as the tapping part descends and squeezes the egg, thus buffering the impact of the tapping part on the egg within a certain range, thereby preventing the impact of the tapping part on the egg from being too great and damaging the integrity of the egg.

[0208] In this embodiment, the shell-knocking device further includes a feed guide trough 421, which has a feed guide channel corresponding to the egg-containing hole, and the feed guide channel can accommodate a limited number of eggs arranged in a single linear row.

[0209] The eggs are temporarily stored in the feed trough and guided into the egg-holding holes, thus preventing the eggs from entering the shell-breaking conveyor line in a disorderly manner, which would cause some eggs to roll away and not be able to be accommodated in the egg-holding holes.

[0210] To facilitate better removal of eggshells, the shell-peeling and sorting module may also include a cooling device 410, which is connected to the shell-knocking device.

[0211] The cooling device includes:

[0212] Cooling tank 411, wherein the cooling tank contains a limited amount of coolant;

[0213] The first lifting conveyor line 412 is installed in the cooling box at its lower part, and the upper part of the first conveyor line is connected to the shell-knocking device 420.

[0214] In this embodiment, the first lifting conveyor line is connected to the aforementioned guide trough, and the cooled poultry eggs are transported to the guide trough through the first lifting conveyor line.

[0215] By first immersing the cooked eggs in a cooling liquid, a larger gap is formed between the eggshell membrane and the albumen due to the different degrees of contraction caused by the cold, making it easier to peel the eggshell.

[0216] In this embodiment, a jacket 413 is provided in the side wall of the cooling box, and a cooling coil 414 connected to the refrigeration device is provided in the jacket.

[0217] The refrigerant is introduced into the cooling coil through a refrigeration unit to exchange heat with the coolant in the cooling tank, thereby maintaining the coolant temperature and avoiding frequent coolant replacements.

[0218] In this embodiment, the coolant can be purified water that has been cooled to a preset temperature.

[0219] Below the first lifting conveyor line, there is also a bottom-inclined return trough 415, which is integrally formed with the cooling box and is located on the top side of the cooling box.

[0220] When the first lifting conveyor line lifts the eggs out of the cooling box, the coolant adhering to the surface of the eggs is drained out from the drain hole of the first conveyor line under the action of gravity, drained into the return tank, and flowed back into the cooling box along the bottom of the return tank.

[0221] Because the shell-cracking device can only break the part of the eggshell that is in contact with the cracking part and a certain range around it, the rest of the shell will remain intact, making it difficult for the shell-peeling device to remove the eggshell.

[0222] Therefore, in order to solve this technical problem, the shelling and sorting module in this embodiment may also include a rolling device 440, which is arranged between the grading device and the shelling device. The rolling device is arranged in accordance with the grading roller group to receive poultry eggs discharged from the grading gap.

[0223] The rolling device includes:

[0224] Feeding conveyor 441, which is connected to the grading device;

[0225] Roller conveyor 443, wherein the roller conveyor is positioned above the feeding conveyor;

[0226] A rolling gap is formed between the rolling conveyor and the feeding conveyor, and the rolling gap increases sequentially from the rolling device at the starting end to the rolling device at the tail end.

[0227] The rolling device at the starting end is a rolling device that receives poultry eggs discharged from the grading roller group at the starting end, and the rolling device at the tail end is a rolling device that receives poultry eggs discharged from the grading roller group at the tail end.

[0228] This embodiment uses a rolling conveyor to compress the eggs and cause them to roll, thereby completely crushing the eggshells and facilitating eggshell removal. By designing multiple rolling devices that match the egg sizes, the system can achieve complete crushing of the eggshells while avoiding damage from crushing excessively large eggs or incomplete crushing of excessively small eggs.

[0229] In this embodiment, two sets of oppositely arranged guide plates 442 are also provided on the feeding conveyor 411. The two sets of guide plates 442 form a guide channel. The guide channel is divided into a feeding section, a transition section and a discharge section from the feeding end to the discharge end. The width of the feeding section of the guide channel is greater than the width of the discharge section. The transition section narrows linearly from the feeding section to the discharge section. The feeding end of the feeding conveyor is the end of the feeding conveyor connected to the grading device.

[0230] In this embodiment, the rolling device may further include two sets of adjusting components. The adjusting components include adjusting rods 444. Rotating the adjusting rods 444 causes the adjusting rods to move vertically. The adjusting rods are connected to the rolling conveyor via a connecting shaft 445. The connecting shaft rotates circumferentially relative to the rolling conveyor, and the adjusting rods rotate circumferentially relative to the connecting shaft.

[0231] By rotating the adjusting rod, the height and angle of the roller conveyor can be adjusted according to the actual usage, improving the flexibility of the device.

[0232] In this embodiment, the roller pressing device may further include a roller pressing frame 446, on which the aforementioned feeding conveyor is fixedly installed. The aforementioned adjusting rod may be threadedly connected to the roller pressing frame, and when the adjusting rod is rotated, the adjusting rod may move linearly along its own axis.

[0233] When the adjusting rods of the two sets of adjusting components are rotated simultaneously, the entire roller conveyor can be driven to move vertically, thereby adjusting the height of the roller conveyor according to the actual situation. When the adjusting rod of one set of adjusting components is rotated, one end of the roller conveyor can be driven to move vertically. At this time, the connecting shaft in the two sets of adjusting components will rotate relative to the roller conveyor, thereby realizing the angle adjustment of the roller conveyor.

[0234] In this embodiment, a second lifting conveyor line 450 can also be provided between the rolling device and the shelling device. The rolled poultry eggs are lifted to the top of the box through the second lifting conveyor line, and the upper discharge end of the second lifting conveyor line is connected to the shelling channel through the material distribution channel.

[0235] In order to reduce harmful bacteria on the surface of poultry eggs, the shelling and sorting module in this embodiment may also include a defoaming device 470, which is connected to the shelling device.

[0236] The defoaming device includes:

[0237] Defoaming box 471, wherein the defoaming box contains a limited amount of disinfectant solution;

[0238] The third lifting conveyor line 472 is located inside the defoaming box 471 at the lower part and extends out of the defoaming box from the opening at the upper part.

[0239] After the eggs are peeled, they are moved into a defoaming box, where disinfectant is applied to the peeled eggs to reduce harmful bacteria on the surface. The disinfected eggs are then lifted out of the defoaming box by a third lifting conveyor line and sent to the next process.
