Description

Technical Field

[0001] This invention relates to the technical field of whole egg powder pretreatment equipment, and in particular to a pretreatment equipment for whole egg powder production. Background Technology

[0002] Egg powder is made from fresh eggs through washing, cracking, separation, pasteurization, and spray drying. Products include whole egg powder, egg yolk powder, egg white powder, and high-functionality egg powder products.

[0003] Existing technologies often employ egg-splitting and cracking machines, such as CN211983659U, to perform egg-splitting operations. However, these machines suffer from the following two problems during use: 1. Before cracking the eggs, they need to be removed in advance by artificial light observation or after cracking the eggs, and the stale eggs with broken yolks need to be removed by manual control. The machine itself does not have the ability to distinguish broken yolk eggs. 2. The egg cracker and egg tray are integrated, and the egg cracker needs to be raised to a certain height to facilitate cracking the egg, so that when the egg liquid flows out, it will be partially blocked by the egg cracker. Summary of the Invention

[0004] Therefore, it is necessary to provide a pretreatment device for whole egg powder production to address the technical problems of difficulty in automatically distinguishing broken yolk eggs and the egg-cracking knife blocking the flow of egg liquid.

[0005] To achieve the above objectives, the present invention provides a pretreatment apparatus for whole egg powder production, comprising: A frame, on which a rotating disc is rotatably mounted; The egg-cracking mechanism includes a fixed frame, which is fixedly mounted on a rotating plate, and an egg-cracking knife is slidably engaged on the fixed frame; The discharging mechanism includes an egg yolk hopper and an egg white hopper, both of which are hinged to a fixed frame. A lifting frame is slidably engaged on the fixed frame, and the lifting frame abuts against both the egg yolk hopper and the egg white hopper. The fixed frame and the lifting frame are provided with the same through slot. A weight sensor and a limit rod are installed on the frame, and a limit block is slidably engaged on the frame.

[0006] By adopting the above technical solution, eggs can be conveyed to the egg-cracking mechanism by the feeding mechanism in the existing technology, and then cracked by the egg-cracking knife. After cracking, the egg-cracking knife can be pushed outward by the egg tray carrying the egg in the egg-cracking mechanism. The egg-cracking knife is slidably engaged with the fixing frame, so that while the egg-cracking knife is pushed away by the egg tray, it can slide along the preset groove on the fixing frame. Finally, while the egg-cracking knife and the egg tray slide outward together, the egg-cracking knife and the egg tray can also separate, thereby avoiding obstruction of the egg liquid flow. After cracking, the yolk falls into the yolk container, and the egg white can fall into the egg white container through the small hole at the bottom of the yolk container. The lifting frame slidably engaged with the egg white container on the fixing frame is connected to the yolk container. Both the egg white and yolk buckets are in contact with each other. As the rotating disc drives the egg white and yolk buckets to circulate, the lifting frame and the bottom of the egg white bucket will slide against the upper surface of the frame. During this process, the weight of the egg white bucket is transferred to the frame, while the weight of the lifting frame and the egg yolk bucket is transferred to the frame via the lifting frame. Therefore, when the rotating disc passes the weight sensor, only the egg white bucket itself and the egg liquid inside will be weighed. When encountering an egg with a runny yolk, because there is no yolk membrane to obstruct it, the egg white and most of the yolk will fall from the yolk bucket into the egg white bucket. Therefore, if the weight of the egg white bucket measured by the weight sensor is higher, then the egg at that point is not fresh and has a runny yolk. When a yolk egg is detected, the weight sensor sends a signal, which triggers an electric cylinder to push the limit block. This ensures that as the yolk and white egg hoppers pass the normal egg feeding area on the frame, the lifting frame is supported by the limit block and will not fall. The lifting frame, in turn, supports the yolk and white egg hoppers, preventing them from rotating during feeding due to hinges. As the rotating disc continues to rotate the yolk and white egg hoppers, the limit rod inserts into the through slot shared by the fixed frame and the un-lowered lifting frame. This prevents the lifting frame from descending after passing the limit block, allowing the limit block to retract and preventing it from limiting the lifting frame at the next location containing normal eggs. When the yolk hopper and egg white hopper are positioned within the unfilled yolk egg feeding area on the frame, they can deflect normally at the hinge, thus emptying the unfilled yolk eggs stored within. When the yolk hopper and egg white hopper containing normal eggs pass the limiting block, they are not stopped, allowing the lifting frame to descend normally. The yolk hopper and egg white hopper can then deflect normally in the normal egg feeding area. When passing the limiting rod, the limiting rod will only insert into the through slot on the fixed frame and will not contact the descending lifting frame, thus completing the automated separation of unfilled yolk eggs and the separate feeding of unfilled yolk eggs and normal eggs. The descending lifting frame will be limited by the hinge end of the egg white hopper and will not completely detach from the fixed frame.

[0007] Optionally, an egg tray is slidably engaged on the fixed frame, an egg-cracking knife is placed on the egg tray, a push block is installed on the fixed frame and is slidably engaged with the egg tray, and a fixed arc plate is installed on the frame, with the push block and the fixed arc plate working together.

[0008] By adopting the above technical solution, when the rotating pusher passes the fixed arc plate fixed on the frame, the two can slide against each other, so that the pusher can be pushed towards the egg tray, and the two symmetrically arranged egg trays can be pushed apart, thereby breaking the eggs with the bottom opening made by the egg-cracking knife to both sides, so that the egg liquid can fall from the middle. While the egg trays are separated to both sides, the egg-cracking knife can be pushed to move outward together.

[0009] Optionally, a swing arm is hinged to the fixed frame, a connecting rod is hinged to the swing arm, a push block is slidably engaged with the connecting rod, an egg tray is fixedly connected to the connecting rod, an L-shaped connecting block is slidably engaged at the bottom of the connecting rod, an egg-cracking knife is fixedly installed on the L-shaped connecting block, and a slanted groove is provided on the fixed frame, in which the egg-cracking knife is slidably engaged.

[0010] By adopting the above technical solution, when the pusher slides inward, it can push the connecting rod. Because the two are set with inclined surfaces of the same angle and the inclined surfaces abut against each other, and through the hinge of the swing arm and the hinge between the swing arm and the connecting rod, the connecting rod can swing upward when it moves outward. That is, the connecting rod can drive the egg tray to move in an upward arc, which makes it easier for the egg tray to break the egg. At the same time as the connecting rod moves, it can drive the L-shaped connecting block to move outward together. Since the egg-cracking knife is slidably engaged in the inclined groove set in the fixed frame, the L-shaped connecting block and the egg-cracking knife can separate from each other with the egg tray while descending, so that the egg-cracking knife will no longer block the egg liquid from flowing out. The egg-cracking knife is an extremely thin blade and fits in close contact with the egg tray when working.

[0011] Optionally, a push rod is installed on the push block, the push rod is slidably engaged with the fixed frame, a ball bearing is rotatably installed on the push rod, the ball bearing is configured to cooperate with the fixed arc plate, a lower pressure arm is hinged on the fixed frame, an elastic component is installed on the fixed frame, the elastic component is fixedly connected to the lower pressure arm, and an arc-shaped lifting plate is installed on the frame.

[0012] By adopting the above technical solution, the ball bearing installed on the push rod drives the push block to abut against the fixed arc plate, thereby driving the ball bearing to rotate and reducing friction during sliding contact. When the pressing arm slides to the arc-shaped lifting plate, it can perform the pressing work through the hinge relationship with the fixed frame, and work with the egg cracker to open the bottom of the egg. After disengaging from the arc-shaped lifting plate, the elastic component can drive the pressing arm to reset. The elastic component can be a customized curved spring to have a longer service life.

[0013] Optionally, a reset block is slidably engaged on the push block, and an elastic component two is installed on the push block, with the elastic component two being fixedly connected to the reset block.

[0014] By adopting the above technical solution, the push block and the reset block abut against both sides of the connecting rod respectively. When the push block pushes the connecting rod away, the reset block can also move away and stretch the elastic component two. When the push rod does not abut against the fixed arc plate on the frame, the elastic component two can drive the connecting rod to reset through the reset block.

[0015] Optionally, a vibrating rod is hinged to the fixed frame, a rotating ring is rotatably mounted on the vibrating rod, a corrugated plate is mounted on the frame, a lifting plate is mounted on the corrugated plate, the lifting plate is located inside the weighing sensor, and a bearing spoon is mounted on the side of the vibrating rod away from the rotating ring.

[0016] By adopting the above technical solution, the rotating ring on the vibrating rod abuts against the corrugated plate. Through the special shape of the corrugated plate, the vibrating rod and the carrying spoon on it can vibrate, thereby shaking off the excess egg white on the carrying spoon, leaving only the egg yolk on the carrying spoon. When the rotating ring passes the lifting plate, it can keep the vibrating rod in a raised state, thus supporting the egg yolk container. At this time, the weight sensor can measure the weight of the egg white container and the lifting frame, thereby avoiding the possibility that the surface of the frame may be uneven due to friction, causing part of the weight of the egg white container to press on the lifting frame, and the inaccurate weighing when only measuring the egg white container.

[0017] Optionally, the carrying spoon is located inside the yolk container and has a gap with the inner wall of the yolk container.

[0018] By adopting the above technical solution, the gap facilitates the falling of egg white. At the same time, when the egg yolk hopper and the vibrating rod deflect at different centers, they will not collide or limit each other.

[0019] Optionally, an extension arc plate is installed on the frame, which is configured to cooperate with the rotating ring, and a water spray head is installed on the frame.

[0020] By adopting the above technical solution, the extended arc plate is located in the yolk feeding area. When the vibrating rod passes by, the rotating ring can abut against the extended arc plate, so that the yolk hopper does not fall and remains in a horizontal state. At the same time, the water spray head can spray pure water to clean the yolk hopper and the carrying spoon, avoiding the problem that the area near the carrying spoon may not be cleaned properly when the yolk hopper is tilted. The cleaned water can flow to the egg white hopper and continue to flow out along the tilted egg white hopper, thereby rinsing the egg white hopper.

[0021] Optionally, a linear actuator is mounted on the frame, and the output end of the linear actuator is connected to the limit block.

[0022] By adopting the above technical solution, the linear actuator can drive the limit block to extend or retract at the appropriate time when the weighing sensor transmits a signal.

[0023] Optionally, a lifting rod is installed on the frame, and the lifting rod is configured in conjunction with the egg white hopper and the lifting frame.

[0024] By adopting the above technical solution, lifting rods are installed in the normal egg feeding area and the loose yolk egg feeding area to lift the lowered lifting frame and the deflected egg white hopper back to their original positions. When the lifting frame rises a certain distance and does not collide with the limiting rod, the limiting rod has already disengaged from the through groove. The limiting rod and lifting rod alternately limit the lifting frame at the location containing loose yolk eggs. During the alternation, a slight collision will occur, but the egg liquid will not flow out from the deeper egg white hopper.

[0025] This technical solution has at least the following beneficial effects: 1. By setting up the discharge mechanism, the egg liquid in the egg white hopper can be weighed. When encountering a broken yolk egg, the weight of the egg increases. The limiting rod can be engaged with the through groove to prevent the egg from deflecting and discharging in the normal egg feeding area, thus achieving the purpose of automated screening of broken yolk eggs. 2. The egg-smashing mechanism allows the egg-smashing knife to slide diagonally on the fixed frame after cracking the egg, thus separating it from the egg tray while also sliding relative to it, preventing the egg liquid from flowing out of the eggshell.

[0027] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Please see Figures 1 to 6 This application provides a pretreatment apparatus for whole egg powder production, comprising: A frame 1 is provided, on which a rotating disk 11 is rotatably mounted. The rotating disk 11 can be driven by a customized servo motor with a suitable speed mounted on the frame 1 in conjunction with a gear set. The egg-cracking mechanism 2 includes several fixed frames 21, which are fixedly installed and spaced apart on the rotating disk 11. Egg-cracking blades 23 are slidably engaged on the fixed frames 21. The discharge mechanism 3 includes an egg yolk hopper 31 and an egg white hopper 32. Both the egg yolk hopper 31 and the egg white hopper 32 are hinged to a fixed frame 21. A lifting frame 33 is slidably engaged on the fixed frame 21. The lifting frame 33 abuts against both the egg yolk hopper 31 and the egg white hopper 32. The fixed frame 21 and the lifting frame 33 are provided with the same through slot 34. A weight sensor 35 and a limit rod 36 are fixedly installed on the frame 1. A limit block 37 is slidably engaged on the frame 1. The upper surface of the weight sensor 35 is flush with the upper surface of the frame 1.

[0029] Eggs can be conveyed to the egg-cracking mechanism 2 by the existing feeding mechanism, and then cracked by the egg-cracking knife 23. After cracking, the egg-cracking knife 23 can be pushed outward by the egg tray carrying the egg in the egg-cracking mechanism 2. The egg-cracking knife 23 is slidably engaged with the fixing frame 21, so that while the egg-cracking knife 23 is pushed away by the egg tray, it can slide along the preset groove on the fixing frame 21. Finally, while the egg-cracking knife 23 and the egg tray slide outward together, the egg-cracking knife 23 can also separate from the egg tray, thereby avoiding obstruction of the egg liquid flow. After cracking, the yolk falls into the yolk container 31, and the egg white can fall into the egg white container 32 through the small hole at the bottom of the yolk container 31. The lifting frame 33 slidably engaged with the egg white container 32 and the egg white container 33 on the fixing frame 21 are connected to the yolk container 31 and the egg white container 32. Both are in contact. During the rotation of the yolk container 31 and the egg white container 32 by the rotating disk 11, the bottom of the lifting frame 33 and the egg white container 32 will slide in contact with the upper surface of the frame 1. During this process, the weight of the egg white container 32 can be transferred to the frame 1, and the weight of the lifting frame 33 and the yolk container 31 can be transferred to the frame 1 by the lifting frame 33. Therefore, during the rotation of the rotating disk 11, when the egg white container 32 passes the weighing sensor 35, only the egg white container 32 itself and the egg liquid inside will be weighed by the weighing sensor 35. When it encounters an egg with a broken yolk, since there is no yolk membrane to block it, the egg white and most of the yolk will fall from the yolk container 31 into the egg white container 32. Therefore, when the weighing sensor 35 measures a larger weight of the egg white container 32, If the eggs here are not fresh and have broken yolks, the weight sensor 35 can send a signal, which will cause the electric cylinder to push the limit block 37. Thus, when the yolk hopper 31 and egg white hopper 32 pass through the normal egg feeding area on the frame 1, the lifting frame 33 will be supported by the limit block 37 and will not fall. The lifting frame 33 also supports the yolk hopper 31 and egg white hopper 32, so they will not rotate due to the hinge. When the rotating disk 11 continues to drive the yolk hopper 31 and egg white hopper 32 to rotate, the limit rod 36 can be inserted into the through slot 34 shared by the fixed frame 21 and the un-lowered lifting frame 33. Thus, after the lifting frame 33 passes the limit block 37, it will be limited by the limit rod 36 and will not descend. When the lifting frame 33 containing normal eggs is retracted, it will not limit the next lifting frame 33 containing normal eggs. When the yolk hopper 31 and egg white hopper 32 are limited to the loose yolk egg feeding area set on the frame 1, they can deflect normally at the hinge, thereby pouring out the loose yolk eggs stored inside. When the yolk hopper 31 and egg white hopper 32 containing normal eggs pass the limit block 37, they will not be limited by it, so the lifting frame 33 can descend normally. The yolk hopper 31 and egg white hopper 32 can deflect normally in the normal egg feeding area. When passing the limit rod 36, the limit rod 36 will only insert into the through groove 34 on the fixed frame 21 and will not contact the lowered lifting frame 33. Finally, the automatic differentiation of loose yolk eggs and the separate feeding of loose yolk eggs and normal eggs are completed.The descending lifting frame 33 will be limited by the hinged end of the egg white container 32 and will not completely detach from the fixed frame 21.

[0030] In one embodiment, two symmetrically arranged egg trays 22 are slidably engaged on the fixed frame 21, and an egg-cracking knife 23 is disposed on the egg trays 22. A push block 24 is fixedly installed on the fixed frame 21, and the push block 24 is slidably engaged with the egg trays 22. A fixed arc plate 25 is fixedly installed on the frame 1, and the push block 24 is configured to cooperate with the fixed arc plate 25.

[0031] By adopting the above technical solution, when the rotating pusher 24 passes the fixed arc plate 25 fixed on the frame 1, the two can slide against each other, so that the pusher 24 can be pushed towards the egg tray 22, and the two symmetrically arranged egg trays 22 can be pushed apart, thereby breaking the eggs with the bottom opening made by the egg-cracking knife 23 to both sides, so that the egg liquid can fall from the middle. While the egg trays 22 are separated to both sides, the egg-cracking knife 23 can be pushed to move outward together.

[0032] In one embodiment, a swing arm 26 is hinged to the fixed frame 21, a connecting rod 27 is hinged to the swing arm 26, a push block 24 is slidably engaged with the connecting rod 27, an egg tray 22 is fixedly connected to the connecting rod 27, an L-shaped connecting block 28 is slidably engaged at the bottom of the connecting rod 27, an egg-cracking knife 23 is fixedly installed on the L-shaped connecting block 28, and a slanted groove is provided on the fixed frame 21, in which the egg-cracking knife 23 is slidably engaged.

[0033] By adopting the above technical solution, when the pusher 24 slides inward, it can push the connecting rod 27. Because the two are set with inclined surfaces of the same angle and the inclined surfaces abut against each other, and through the hinge of the swing arm 26 and the hinge between the swing arm 26 and the connecting rod 27, the connecting rod 27 can swing upward when it moves outward. That is, the connecting rod 27 can drive the egg tray 22 to move in an upward arc, so that the egg tray 22 can easily break the egg. While the connecting rod 27 moves, it can drive the L-shaped connecting block 28 to move outward together. Since the egg-cracking knife 23 is slidably engaged in the inclined groove set on the fixed frame 21, the L-shaped connecting block 28 and the egg-cracking knife 23 can separate from each other with the egg tray 22 and descend at the same time, so that the egg-cracking knife 23 will no longer block the egg liquid from flowing out. The egg-cracking knife 23 is an extremely thin blade and fits in close contact with the egg tray 22 when working.

[0034] In one embodiment, a push rod 29 is fixedly installed on the push block 24. The push rod 29 is slidably engaged with the fixed frame 21. A ball bearing 201 is rotatably installed on the push rod 29. The ball bearing 201 is configured to cooperate with the fixed arc plate 25. A lower pressure arm 202 is hinged on the fixed frame 21. An elastic component 1 is fixedly installed on the fixed frame 21. The elastic component 1 can be a spring. The elastic force output end of the elastic component 1 is fixedly connected to the lower pressure arm 202. An arc-shaped lifting plate is installed on the frame 1. The lower pressure arm 202 is configured to cooperate with the arc-shaped lifting plate.

[0035] By adopting the above technical solution, the ball bearing 201 installed on the push rod 29 drives the push block 24 to abut against the fixed arc plate 25, thereby pushing the ball bearing 201 to rotate and reducing friction during sliding contact; when the pressing arm 202 slides to the arc-shaped lifting plate, it can perform the pressing work through the hinge relationship with the fixed frame 21, and work with the egg cracker 23 to open the bottom of the egg. When it is separated from the arc-shaped lifting plate, the elastic component can drive the pressing arm 202 to reset. The elastic component can be a customized curved spring to have a longer service life.

[0036] In one embodiment, a reset block 203 is slidably engaged on the push block 24, and an elastic component 204 is fixedly installed on the push block 24. The elastic component 204 can be a spring, and the spring can be a customized spring to have a longer service life. The elastic component 204 is located on the side away from the connecting rod 27, and the elastic component 204 is fixedly connected to the reset block 203.

[0037] By adopting the above technical solution, the push block 24 and the reset block 203 respectively abut against the two sides of the connecting rod 27. When the push block 24 pushes the connecting rod 27 away, the reset block 203 can also move away and stretch the elastic component 204. When the push rod 29 does not abut against the fixed arc plate 25 on the frame 1, the elastic component 204 can drive the connecting rod 27 to reset through the reset block 203.

[0038] In one embodiment, a vibration rod 38 is hinged to the fixed frame 21, a rotating ring 39 is rotatably mounted on the vibration rod 38, a corrugated plate 301 is fixedly mounted on the frame 1, a lifting plate 302 is fixedly mounted on the corrugated plate 301, the lifting plate 302 is located inside the weighing sensor 35, and a carrying spoon 303 is fixedly mounted on the side of the vibration rod 38 away from the rotating ring 39.

[0039] By adopting the above technical solution, the rotating ring 39 on the vibrating rod 38 abuts against the wave plate 301. Through the special shape of the wave plate 301, the vibrating rod 38 and the carrying spoon 303 on it can vibrate, thereby shaking off the excess egg white on the carrying spoon 303, leaving only the egg yolk on the carrying spoon 303. When the rotating ring 39 passes the lifting plate 302, the vibrating rod 38 can be kept in a raised state, which can support the egg yolk container 31. At this time, the weight sensor 35 can measure the weight of the egg white container 32 and the lifting frame 33, thereby avoiding the possibility that the surface of the frame 1 may be uneven due to friction, causing part of the weight of the egg white container 32 to press on the lifting frame 33, and the inaccurate weight measurement when only measuring the egg white container 32.

[0040] In one embodiment, the carrying spoon 303 is located inside the yolk container 31 and has a gap with the inner wall of the yolk container 31.

[0041] By adopting the above technical solution, the gap can facilitate the falling of egg white. At the same time, when the egg yolk hopper 31 and the vibrating rod 38 deflect at different centers, they will not collide and limit each other.

[0042] In one embodiment, an extension arc plate 304 is fixedly installed on the frame 1, and the extension arc plate 304 is configured to cooperate with the rotating ring 39. A water spray head is fixedly installed on the frame 1.

[0043] By adopting the above technical solution, the extended arc plate 304 is located in the yolk feeding area. When the vibrating rod 38 passes by, the rotating ring 39 can abut against the extended arc plate 304, so that the yolk hopper 31 does not fall and remains in a horizontal state. At the same time, the water spray head can spray pure water to clean the yolk hopper 31 and the carrying spoon 303, avoiding the problem that the area near the carrying spoon 303 may not be cleaned properly when the yolk hopper 31 is tilted. The cleaned water can flow to the egg white hopper 32 and continue to flow out along the tilted egg white hopper 32, thereby rinsing the egg white hopper 32.

[0044] In one embodiment, a linear actuator 305 is fixedly installed on the frame 1. The linear actuator 305 may be an electric cylinder, and the output end of the linear actuator 305 is fixedly connected to the limit block 37.

[0045] By adopting the above technical solution, the linear actuator 305 can drive the limit block 37 to extend or retract at an appropriate time when the weighing sensor 35 transmits a signal.

[0046] In one embodiment, a lifting rod 306 is fixedly installed on the frame 1, and the lifting rod 306 is configured in conjunction with the egg white container 32 and the lifting frame 33.

[0047] By adopting the above technical solution, the lifting rod 306 is installed in the normal egg feeding area and the loose yolk egg feeding area to lift the lowered lifting frame 33 and the deflected egg white hopper 32 back to their original positions. When the lifting frame 33 rises a certain distance and does not collide with the limiting rod 36, the limiting rod 36 has already disengaged from the through groove 34. The limiting rod 36 and the lifting rod 306 alternately limit the lifting frame 33 containing loose yolk eggs. During the alternation, a slight collision will occur, but the egg liquid will not flow out from the deeper egg white hopper 32.
