Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically to a raw material impurity removal device and method for food processing. Background Technology

[0002] Food raw material impurity removal is a core pretreatment process before food processing. Its purpose is to remove inorganic impurities (sand, metal, glass, etc.), organic impurities (weeds, insect carcasses, moldy particles, seeds of foreign plants, etc.), and other foreign objects from the raw materials to ensure the safety, quality stability, and efficiency of subsequent processing of food.

[0003] CN215197565U discloses a mobile iron removal device for food production, comprising a housing with a feeding hopper connected to its upper surface. A rotating rod is installed inside the feeding hopper, and a baffle is fixedly fitted onto the outer wall of the rotating rod. One end of the rotating rod penetrates the inner wall of the feeding hopper and extends outside the hopper. The housing contains a first conveying iron removal device and a second conveying iron removal device. This application, through the combination of the rotating rod, baffle, and ratchet, can control the amount of food raw material entering the housing through the feeding hopper, thereby preventing accumulation of the food raw material during iron removal. By using a sleeve and a fixed pipe, the food raw material is agitated during the process, causing iron slag above the food raw material to fall below, preventing the slag from being too far from the magnet and thus making it difficult for the magnet to attract and remove the iron slag.

[0004] In existing technology, food raw materials enter the housing through the feed hopper of the aforementioned device and then fall into the iron removal device inside the housing for iron removal. However, in actual operation, it has been found that because a set of baffles is installed inside the feed hopper, the food raw materials are blocked by the baffles before reaching the iron removal device. The purpose of this is to control the amount of food raw materials fed. Only after a certain amount is reached will the baffles open, allowing the food raw materials to fall. However, this feeding method has a problem: the food raw materials accumulate in the feed hopper after being blocked by the baffles. When the baffles open, the accumulated raw materials fall all at once and accumulate on the conveyor belt of the iron removal device, resulting in uneven thickness of food raw materials on the conveyor belt. This is not conducive to the smooth progress of iron removal, and thus affects the iron removal effect, which has an adverse impact on subsequent processing. Summary of the Invention

[0014] A method for removing impurities from raw materials used in food processing includes the following steps: S1. Food ingredients are placed in a storage bin and stirred by a stirring rod inside the storage bin to prevent clumping. When impurities need to be removed, the conveyor blades are driven to rotate and the food ingredients are transported to the conveyor belt. S2, while conveying, drives the discharge pipe to move back and forth, so that the food raw materials are evenly sprinkled on the conveyor belt. At the same time, it drives the front cleaning toothed disc to rotate, and uses the cleaning toothed disc to clean and thin the food raw materials to avoid the accumulation of food raw materials. S3, the processed food raw materials are conveyed to the magnetic separator group one by the conveyor belt. The two sets of magnetic blocks in the magnetic separator group one are used to remove impurities. When cleaning the magnetic separator group one, the food raw materials are guided to the magnetic separator group two by the movable plate and the guide plate to continue to remove impurities. After the magnetic separator group one is cleaned, the food raw materials are guided to the magnetic separator group one again for impurity removal. Then the magnetic separator group two is cleaned.

[0015] The beneficial effects of this invention are: (1) The present invention drives the rotating screw in the moving chamber to rotate, thereby driving the cleaning plate and the triangular block to move simultaneously. While the triangular block moves, it lifts the movable plate under the conveyor belt, thereby changing the track of the food raw material falling, so that the food raw material falls onto the guide plate and is then guided to the magnetic separator group two. The cleaning plate cleans the magnetic separator group one. After the magnetic separator group one is cleaned, the triangular block does not contact the abutment bar, the movable plate returns to the initial position, and then the magnetic separator group two is cleaned. Through the cooperation of the movable plate and the triangular block, the magnetic separator group one and the magnetic separator group two can be used interchangeably. When used interchangeably, the cleaning plate can be driven to clean the magnetic block, thereby improving the impurity removal efficiency without stopping the machine.

[0016] (2) The present invention uses a turntable and a rotating plate in the drive mechanism to drive the discharge pipe to move back and forth while the discharge pipe is discharging. During the back and forth movement, the food raw materials are evenly sprinkled on the conveyor belt. At the same time, the rotating plate uses the drive teeth at the end to drive the front cleaning plate to move back and forth, thereby driving the cleaning toothed disc below to rotate, breaking up and thinning the food raw materials on the conveyor belt, and preventing the food raw materials on the conveyor belt from accumulating.

[0017] (3) The present invention drives the stirring rod and scraper to rotate by the stirring shaft. When the stirring rod rotates, the food raw materials in the storage bucket can be prevented from clumping. At the same time, the food raw materials can be scraped to the connecting pipe by the rotation of the scraper, and then discharged from the connecting pipe into the conveying chamber. Meanwhile, when the stirring shaft rotates, it drives the external drive column and drive pulley to rotate. Through the setting of the drive pulley and driven pulley, the turntable and the rotating plate are driven to work, so as to realize the uniform feeding and thinning of food raw materials.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-10 As shown, this application provides a raw material impurity removal device for food processing, including a storage tank 1, and further comprising: Conveying mechanism 2 is located below storage bin 1; Thinning mechanism 3 is located below conveying mechanism 2; The conveying mechanism 4 is located below the thinning mechanism 3; The magnetic separation mechanism 5 is located below the conveying mechanism 4; Drive mechanism 6 is located below conveyor mechanism 2; Food ingredients are placed in storage bin 1, and then conveyed to conveying mechanism 4 by conveying mechanism 2. Then, the food ingredients on conveying mechanism 4 are thinned by thinning mechanism 3 to avoid accumulation. The thinned food ingredients fall to magnetic separation mechanism 5 to complete the impurity removal work. During operation, the food ingredients are first placed in the storage bin 1, which can stir the food ingredients to prevent them from clumping. When impurity removal is required, the food ingredients are transported to the conveying mechanism 4 below using the conveying mechanism 2. Then, the thinning mechanism 3 is used to thin the food ingredients. Finally, the food ingredients are transported to the magnetic separation mechanism 5 through the conveying mechanism 4 for impurity removal.

[0023] like Figure 2 and Figure 7 As shown, the magnetic separation mechanism 5 includes a magnetic separation group one 51 and a magnetic separation group two 53; the magnetic separation group one 51 and the magnetic separation group two 53 are composed of four sets of magnetic blocks; the tops of the magnetic separation group one 51 and the magnetic separation group two 53 are respectively fixedly connected to a moving chamber one 52 and a moving chamber two 54; a moving screw 521 is rotatably connected inside the moving chamber one 52 and the moving chamber two 54; a moving plate 524 is threadedly connected to the moving screw 521; a cleaning plate 57 is fixedly connected to the moving plate 524; the cleaning plate 57 abuts against the magnetic blocks; a collecting magnetic plate 571 is fixedly connected to the bottom of the cleaning plate 57; a collecting chamber 58 is fixedly connected to the side walls of the magnetic separation group one 51 and the magnetic separation group two 53; a cleaning brush 58 is fixedly connected inside the collecting chamber 58. 1; The cleaning brush 581 and the collecting magnetic plate 571 are in movable contact; The conveying mechanism 4 includes a transmission plate 41; A conveyor belt 42 is rotatably mounted on the side wall of the transmission plate 41; A movable plate 43 is rotatably connected to the bottom of the transmission plate 41; A fixing block 44 and an abutment strip 45 are fixedly connected to the bottom of the movable plate 43; The fixing block 44 is located on both sides of the abutment strip 45; A pulley 441 is rotatably connected to the fixing block 44; A triangular block 522 is fixedly connected to the top of the moving plate 524; A roller 523 is rotatably connected to the top of the triangular block 522; The triangular block 522 is located above the moving chamber 1 52; The magnetic separator 1 51 is located below the conveyor belt 42; A guide plate 56 is fixedly connected to the top of the magnetic separator 2 53; During operation, food ingredients fall onto conveyor belt 42 and are thinned by thinning mechanism 3 on conveyor belt 42. The thinned food ingredients are then conveyed by conveyor belt 42 to the lower movable plate 43, and then guided by the movable plate 43 to magnetic separator group 51. Magnetic separator group 51 and magnetic separator group 53 consist of four magnetic blocks, grouped in pairs. In the initial state, the movable plate 43 guides the food ingredients into magnetic separator group 51. The two sets of magnetic blocks in magnetic separator group 51 then adsorb metallic impurities in the food ingredients. The cleaned food ingredients pass through magnetic separator group 51 and fall below to be collected. After a period of operation, the magnetic blocks may have accumulated a large amount of impurities. Excessive adsorption of impurities can affect subsequent adsorption capacity. At this point, the moving chamber 5 is activated. The movable screw 521 inside plate 2 rotates, which drives the movable plate 524 and the cleaning plate 57 to move. As the movable plate 524 moves, it drives the upper triangular block 522 to move. When the triangular block 522 moves, it approaches the pulley 441 below the movable plate 43 and then abuts against the pulley 441. Simultaneously, as the movable plate 524 moves, the inclined surface of the triangular block 522 presses against the movable plate 43. At the same time, the sliding of the pulley 441 causes the movable plate 43 to rise. As the movable plate 43 rises, the pulley 441 gradually contacts the roller 523 at the top of the triangular block 522. At this point, the movable plate 43 has risen to its highest point. Then, the movable plate 524 continues to move, causing the roller 523 to pass over the pulley 441 and contact the rear abutment bar 45. Roller 523 rotates on contact bar 45, and simultaneously lifts movable plate 43 via triangular block 522. After movable plate 43 is lifted, the food raw materials on conveyor belt 42 change direction. Due to the increased height of movable plate 43, the food raw materials will not slide down to magnetic separator group 1 51, but will slide onto guide plate 56 on magnetic separator group 2 53, and then be guided into magnetic separator group 2 53 for impurity removal. Simultaneously with the movement of movable plate 524, cleaning plate 57 also moves. As cleaning plate 57 moves, it scrapes and cleans the surface of the magnetic blocks on magnetic separator group 1 51. The scraped impurities fall below cleaning plate 57 and are re-absorbed by collecting magnetic plate 571 below cleaning plate 57, preventing the cleaned impurities from mixing with other materials. When the cleaning plate 57 moves to the edge of the magnetic separator group 51 after impurity removal, the collecting magnetic plate 571 contacts the cleaning brush 581 in the side collection chamber 58. The cleaning brush 581 sweeps the impurities on the collecting magnetic plate 571 into the collection chamber 58. When the triangular block 522 moves to the other side of the movable plate 43, the roller 523 on the triangular block 522 does not contact the abutment bar 45. Then the movable plate 43 descends and returns to its initial position. Subsequent food materials will no longer be guided to the guide plate 56. At the same time, the magnetic separator group 51 has been cleaned and will continue to be used for impurity removal. During this time, the moving screw 521 in the moving chamber 54 is driven to rotate, which moves the cleaning plate 57 in the magnetic separator group 53.The cleaning process of the magnetic separator is completed. After the second magnetic separator 53 is cleaned, the triangular block 522 moves again, lifting the movable plate 43 and guiding the food raw materials into the second magnetic separator 53. This process is repeated continuously to remove impurities from the food raw materials without stopping the operation, thus improving cleaning efficiency.

[0024] like Figure 5 and Figure 6 As shown, the thinning mechanism 3 includes a fixed plate 31; the fixed plate 31 is fixedly connected to the transmission plate 41; the fixed plate 31 has two sets; a cleaning plate 32 is slidably connected to the fixed plate 31; a mounting base 34 is fixedly connected to the bottom of the cleaning plate 32; a cleaning toothed disc 35 is rotatably connected to the mounting base 34; the cleaning toothed disc 35 is located above the conveyor belt 42; three sets of cleaning toothed discs 35 are provided, all meshing with each other; a driven gear 36 is rotatably connected to the mounting base 34; two sets of driven gears 36 are provided; the output end of the driven gear 36 is fixedly connected to the input end of the cleaning toothed disc 35; a connecting rack 311 is fixedly connected to the side wall of the fixed plate 31; the connecting rack 311 is movably meshed with the driven gear 36. During operation, when food ingredients arrive at the conveyor belt 42, the conveyor belt 42 transports the food ingredients to below the mounting base 34. Then, the drive mechanism 6 drives the cleaning plate 32 to move back and forth. During this back-and-forth movement, it drives the cleaning toothed disc 35 and the driven gear 36 on the mounting base 34 to move back and forth. There are two sets of driven gears 36, which are respectively located on both sides of the mounting base 34 and connected to the cleaning toothed discs 35 on both sides. During the back-and-forth movement, the connecting rack 311 on the side wall of the fixed plate 31 meshes with the driven gear 36, driving the driven gear 36 to rotate. The rotation of the driven gear 36 drives the corresponding cleaning toothed disc 35. The rotating mechanism, via a set of cleaning toothed discs 35, drives the other two sets of cleaning toothed discs 35 to rotate. When the cleaning toothed discs 35 rotate, they can break up and thin the food ingredients on the conveyor belt 42, preventing the food ingredients on the conveyor belt 42 from being too thick and affecting the subsequent impurity removal work. In addition, while the mounting base 34 moves back and forth, the direction of rotation of the cleaning toothed discs 35 is not consistent. When moving to the left, the cleaning toothed discs 35 rotate clockwise, and when moving to the right, the cleaning toothed discs 35 rotate counterclockwise. Through bidirectional rotation, the food ingredients on the conveyor belt 42 can be prevented from being swept in one direction, which would cause the magnetic blocks to be attracted on one side during the subsequent impurity removal, affecting the impurity removal effect.

[0025] like Figure 4As shown, the drive mechanism 6 includes a drive base 61; a turntable 62 and a rotating plate 63 are rotatably connected to the drive base 61; a rotating column 621 is rotatably connected to the turntable 62; a sliding groove 631 is provided on the rotating plate 63; the rotating column 621 is located in the sliding groove 631; a drive tooth 67 is provided at the end of the rotating plate 63; a connecting tooth 321 is provided on the side wall of the cleaning plate 32; the drive tooth 67 is engaged with the connecting tooth 321. During operation, when the conveyor belt 42 transports food raw materials, it drives the turntable 62 on the drive base 61 to rotate. When the turntable 62 rotates, it drives the rotating plate 63 to move back and forth through the rotating column 621. When the rotating plate 63 moves back and forth, it drives the cleaning plate 32 to move back and forth through the drive teeth 67 and the connecting teeth 321, thereby realizing the rotation of the cleaning toothed disc 35 and thinning the food raw materials.

[0026] like Figure 2 As shown, the conveying mechanism 2 includes a conveying chamber 21; conveying blades 22 are rotatably connected inside the conveying chamber 21; a discharge pipe 24 is rotatably connected to the bottom of the conveying chamber 21; one end of the discharge pipe 24 away from the conveying chamber 21 is fixedly connected to a rotating plate 63; a connecting plate 64 is fixedly connected to the drive base 61; one end of the connecting plate 64 away from the drive base 61 is fixedly connected to the conveying chamber 21. When food ingredients need to be transported during operation, the conveying blades 22 inside the conveying chamber 21 are driven to rotate, and the food ingredients are transported to the discharge pipe 24 through the conveying blades 22. At the same time, the discharge pipe 24 is fixedly connected to the rotating plate 63. When the rotating plate 63 moves back and forth, it will also drive the discharge pipe 24 to move back and forth, so that the food ingredients are evenly sprinkled on the conveyor belt 42 and avoid accumulation.

[0027] like Figure 2 As shown, a stirring shaft 12 is rotatably connected inside the storage tank 1; a stirring rod 121 and a scraper 122 are fixedly connected to the stirring shaft 12; the scraper 122 is located below the stirring rod 121; a connecting pipe 14 is fixedly connected to the bottom of the storage tank 1; one end of the connecting pipe 14 away from the storage tank 1 is fixedly connected to the conveying chamber 21. During operation, the stirring shaft 12 drives the stirring rod 121 and scraper 122 to rotate, which can prevent the food raw materials in the storage tank 1 from clumping. At the same time, the rotation of the scraper 122 can scrape the food raw materials to the connecting pipe 14, and then discharge them from the connecting pipe 14 into the conveying chamber 21.

[0028] like Figure 2As shown, a driven pulley 66 is rotatably connected to the bottom of the drive base 61; the output end of the driven pulley 66 is fixedly connected to the input end of the turntable 62; a drive column 15 is rotatably connected to the bottom of the storage tank 1; the input end of the drive column 15 is fixedly connected to the output end of the stirring shaft 12; a drive pulley 151 is fixedly connected to the end of the drive column 15 away from the storage tank 1; a connecting belt 661 is sleeved on the driven pulley 66 and the drive pulley 151. When the stirring shaft 12 rotates, it drives the external drive column 15 and drive pulley 151 to rotate. Then, through the connecting belt 661, it drives the driven pulley 66 to rotate, thereby realizing the rotation of the turntable 62. This drives the rotating plate 63 and the discharge pipe 24 to move back and forth, thereby realizing the rotation of the cleaning toothed disc 35 and thinning the food raw materials on the conveyor belt 42.

[0029] like Figure 2 As shown, a stirring motor 13 is fixedly connected to the top of the storage hopper 1; the stirring shaft 12 is driven by the stirring motor 13; a conveying motor 23 is fixedly connected to the side wall of the conveying chamber 21; the conveying blades 22 are driven by the conveying motor 23; a fixing arm 55 is fixedly connected to the side walls of magnetic separator group one 51 and magnetic separator group two 53; magnetic separator group one 51 and magnetic separator group two 53 are connected by the fixing arm 55; a limiting plate 65 is fixedly connected to the drive base 61; the rotating plate 63 is limited by the limiting plate 65. During operation, the stirring motor 13 and the conveying motor 23 drive the stirring shaft 12 and the conveying blade 22 to rotate, respectively. Both the stirring motor 13 and the conveying motor 23 are shaft motors. The moving lead screw 521 in the moving chamber 1 52 and the moving chamber 2 54 is a trapezoidal lead screw, which can convert rotary motion into linear motion. At the same time, the magnetic blocks in the magnetic separation group 1 51 and the magnetic separation group 2 53 are fixed to each other by the fixed arm 55 and are set below the conveyor belt 42. The limiting plate 65 is used to limit the rotating plate 63 to prevent the rotating plate 63 from shaking or deviating.

[0030] Please see Figures 1-10 As shown, this application provides a method for removing impurities from raw materials used in food processing, comprising the following steps: S1, put the food raw materials into the storage bucket 1, and stir them by the stirring rod 121 in the storage bucket 1 to prevent the food raw materials from clumping. When it is necessary to remove impurities, drive the conveyor blades 22 to rotate and use the conveyor blades 22 to transport the food raw materials onto the conveyor belt 42. S2, while conveying, drives the discharge pipe 24 to move back and forth, so that the food raw materials are evenly sprinkled on the conveyor belt 42. At the same time, drives the front cleaning toothed disc 35 to rotate, and uses the cleaning toothed disc 35 to clean and thin the food raw materials to avoid the accumulation of food raw materials. S3, the processed food raw materials are conveyed to the magnetic separator group 1 51 by the conveyor belt 42. The two sets of magnetic blocks in the magnetic separator group 1 51 are used for impurity removal. When cleaning the magnetic separator group 1 51, the movable plate 43 and the guide plate 56 are used to guide the food raw materials to the magnetic separator group 2 53 for further impurity removal. After the magnetic separator group 1 51 is cleaned, the food raw materials are guided to the magnetic separator group 1 51 for impurity removal. Then the magnetic separator group 2 53 is cleaned. During operation, food ingredients are placed in storage bin 1 and stirred by stirring rod 121 inside storage bin 1 to prevent clumping. When impurity removal is required, the conveyor blades 22 are driven to rotate, and the food ingredients are conveyed onto the conveyor belt 42. At the same time, the discharge pipe 24 is driven to move back and forth, so that the food ingredients are evenly sprinkled on the conveyor belt 42. Simultaneously, the front cleaning toothed disc 35 is driven to rotate, and the cleaning toothed disc 35 is used to clean and thin the food ingredients to prevent accumulation. The processed food ingredients are conveyed to magnetic separator group 1 51 by the conveyor belt 42. Impurity removal is carried out by two sets of magnetic blocks in magnetic separator group 1 51. When cleaning magnetic separator group 1 51, the movable plate 43 and the guide plate 56 are used to guide the food ingredients to magnetic separator group 2 53 for further impurity removal. After magnetic separator group 1 51 is cleaned, the food ingredients are guided back to magnetic separator group 1 51 for impurity removal, and then magnetic separator group 2 53 is cleaned.

[0031] The working principle of this invention is as follows: First, food ingredients are placed in the storage bin 1. When impurity removal is required, the lower conveying chamber 21 is activated. Simultaneously, the stirring shaft 12 inside the storage bin 1 is driven to rotate. The stirring rod 121 first breaks up the food ingredients to prevent clumping. Then, the scraper 122 scrapes the food ingredients into the connecting pipe 14, and then they enter the conveying chamber 21 from the connecting pipe 14. The conveying blades 22 then transport the food ingredients onto the conveyor belt 42. At the same time, as the stirring shaft 12 rotates, the external drive column 15 and drive pulley 151 drive the conveyor belt 42 to rotate. The rotating pulley 66 drives the turntable 62 and the rotating plate 63 to work. When the rotating plate 63 is working, it drives the discharge pipe 24 to move back and forth on the conveyor belt 42, so that the food raw materials are evenly sprinkled on the conveyor belt 42 and avoid accumulation in one place. At the same time, when the rotating plate 63 rotates, it also drives the cleaning plate 32 to move back and forth through the drive tooth 67 at the end. When the cleaning plate 32 moves back and forth, it cooperates with the connecting rack 311 below to drive the cleaning toothed disc 35 in the mounting base 34 to rotate, and uses the cleaning toothed disc 35 to evenly spread the food raw materials on the conveyor belt 42. The food ingredients are dispersed and thinned. Finally, the food ingredients are conveyed by the conveyor belt 42 to the movable plate 43, and then slide down the movable plate 43 into the magnetic separator group 51. Then, the metal impurities in the food ingredients are adsorbed by the two sets of magnetic blocks in the magnetic separator group 51. The food ingredients that have been cleaned are collected from the magnetic separator group 51. When the magnetic blocks in the magnetic separator group 51 have adsorbed a large number of metal impurities, the moving screw 521 in the moving chamber 52 is driven to rotate, which drives the cleaning plate 57 and the triangular block 522 to move. When the triangular block 522 moves, it can lift the movable plate 43, so that the movable plate... The falling trajectory of 43 changes, thus guiding the food raw materials to the guide plate 56. The food raw materials are then guided to the magnetic separator group 2 53 by the guide plate 56. During this time, the magnetic separator group 1 51 can be cleaned by the cleaning plate 57. After cleaning, the movable plate 43 loses the abutment of the triangular block 522 and returns to its initial position, guiding the food raw materials to the magnetic separator group 1 51 again. Then the magnetic separator group 2 53 can be cleaned. Finally, the cleaned-up metal impurities will be adsorbed by the collecting magnetic plate 571 and then enter the collecting chamber 58 for cleaning by the cleaning brush 581.

All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
