Description

Technical Field

[0001] The present invention relates to the field of salted duck egg pickling, and particularly to an intelligent salted duck egg pickling system and method. Background Art

[0002] As a special dish, salted duck eggs have a large demand in the market. For the pickling of traditional salted duck eggs, the static immersion method in salt water can be adopted. However, since the salted eggs are often static during the pickling process, there are differences in the salt concentration between the upper and lower layers of the pickling materials in the liquid, resulting in uneven pickling of the salted eggs and significant differences in the taste after pickling. Moreover, as the pickling time prolongs, the salted egg yolks will sink to the bottom and stick to the shell, damaging the shape of the egg yolks. When the egg yolks need to be taken out for fine processing, it is difficult to completely separate the egg yolks from the eggshells when opening the shell, which not only greatly affects the aesthetics of the egg yolks but also reduces the production efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide an intelligent salted duck egg pickling system and method, which can make the duck eggs rotate with the duck egg wire rack in the pickling pool, and at the same time make the salt water concentration more uniform through aeration and spraying methods, improving the pickling uniformity of salted duck eggs.

[0004] To achieve the above purpose, the present invention provides an intelligent salted duck egg pickling system, including a pickling pool. An aeration device and a salt water spraying device communicated with the bottom of the pickling pool are respectively arranged at the bottom and the upper part of the inner cavity of the pickling pool. A rotary drive assembly is arranged on the pickling pool. The rotary drive assembly includes a rotary motor and a driving gear that are linked. The driving gear is located in the inner cavity of the pickling pool. It further includes a duck egg wire rack that can be placed in the pickling pool. Both ends of the duck egg wire rack are rotatably connected with limit hanging brackets, and the limit hanging brackets are detachably matched with the pickling pool. One end of the duck egg wire rack is also fixedly connected with a driven gear, and the driven gear meshes with the driving gear.

[0005] As a further improvement of the present invention, the duck egg wire rack includes a first outer frame and a second outer frame. One side of the two is rotatably connected through a first hinge, and the other ends are connected through a first locking structure. A first net plate is connected inside the first outer frame, and a plurality of first porous covers are arranged on the first net plate. A second net plate is connected inside the second outer frame, and a plurality of second porous covers are arranged on the second net plate. The first porous covers and the second porous covers are arranged oppositely.

[0006] As a further improvement of the present invention, both ends of the second outer frame are provided with first rotating shafts. A driven gear is connected to one of the first rotating shafts, and the driven gear is located above the driving gear. The two first rotating shafts are respectively rotatably connected with the limit hanging brackets on both sides.

[0007] As a further improvement of the present invention, the limiting hanging bracket includes a cross bar, a limiting block, and a longitudinal hanging bracket connected in sequence. The first rotating shaft of the second outer frame is rotatably connected to the longitudinal hanging bracket. A guiding track is provided on the inner side wall of the pickling tank, and the longitudinal hanging bracket is in sliding fit with the guiding track up and down.

[0008] As a further improvement of the present invention, locking brackets are connected to both sides of the pickling tank, and the locking brackets are adapted to the cross bar. The locking bracket includes a swinging frame and a fixed frame arranged respectively above and below. The fixed frame is connected to the pickling tank. One side of the swinging frame and the fixed frame is rotatably connected through a second hinge, and the other side is connected through a second locking structure. A first pressing groove is provided on the swinging frame, and a second pressing groove is provided on the fixed frame. The first pressing groove and the second pressing groove jointly clamp the cross bar in the middle.

[0009] As a further improvement of the present invention, the brine spraying device includes two first main pipes. A plurality of nozzles arranged along the length direction are connected to each first main pipe. The nozzles on the two first main pipes are respectively located on both sides of the inner cavity of the pickling tank and face the duck egg wire rack. A drain pipe is connected to the bottom of the pickling tank. An electric control valve is connected beside the drain pipe. The electric control valve is communicated with the two first main pipes through a return water pipe, and a water pump is connected to the return water pipe.

[0010] As a further improvement of the present invention, the aeration device includes an aeration pump, a second main pipe, an aeration branch pipe, and an aeration nozzle connected in sequence along the gas flow direction. The aeration nozzle is located at the bottom of the inner cavity of the pickling tank.

[0011] To achieve the above object, the present invention also provides an intelligent pickling method for salted duck eggs. First, put the duck eggs into the duck egg wire rack, move the duck egg wire rack into the pickling tank filled with brine and submerge it below the brine level, so that the driven gear meshes with the driving gear. The rotation driving assembly drives the duck egg wire rack to rotate in the brine. The aeration device stirs the brine at the bottom of the pickling tank through aeration. At the same time, the brine spraying device pumps out the brine at the bottom of the pickling tank and sprays it back into the pickling tank, so as to keep the brine concentration in the pickling tank uniform.

[0012] Advantageous Effects

[0013] Compared with the prior art, the advantages of the intelligent pickling system and method for salted duck eggs of the present invention are as follows:

[0014] 1. After the duck egg wire rack filled with duck eggs is put into the pickling tank, since the driven gear of the duck egg wire rack meshes with the driving gear of the rotation driving assembly, the duck eggs can be turned over in the brine of the pickling tank along with the duck egg wire rack. At the same time, by means of aeration at the bottom of the tank and spraying at the upper part of the pickling tank, the brine in the pickling tank is stirred, so that the brine concentration is more uniform, thereby improving the pickling uniformity of the salted duck eggs and finally ensuring that the saltiness of each part of the pickled salted duck eggs is basically the same.

[0015] 2. During the pickling process, the duck eggs absorb salt and discharge moisture, causing the salt concentration of the pickling material in the pickling tank to decrease. By replenishing salt during the pickling process to correct the salt concentration, ensuring that the salt concentration of the pickling material in the pickling environment is consistent is beneficial for the uniform ripening of the salted egg yolks and improving the penetration degree. By means of aeration, the static pickling of the salted eggs is changed to dynamic pickling. Aeration can cause slight vibrations during the pickling process of the salted eggs, so that even when the egg yolks sink to the bottom, it is not easy to stick to the shell. This can improve the problem of the shape of the egg yolks being affected by sinking to the bottom, and also make it easier to separate the egg yolks from the eggshells, thereby improving production efficiency.

[0016] 3. In the duck egg wire rack, by relatively flipping the first outer frame and the second outer frame, the first wire mesh plate and the second wire mesh plate move away from or close to each other. When they are close to each other, the duck eggs can be wrapped in the middle by the first porous cover body and the second porous cover body, thereby realizing the limitation of the duck eggs and preventing the eggshells from cracking due to large-scale shaking between the two wire mesh plates.

[0017] 4. The duck egg wire rack can be taken out of the pickling tank together with the limiting hanging frame, which is convenient for personnel to load and unload the duck egg wire rack outside the pickling tank without being interfered by the pool wall of the pickling tank, and the operation is more convenient.

[0018] 5. The guiding track on the inner side wall of the pickling tank can prevent the longitudinal hanging frame of the limiting hanging frame from shaking left and right, while the locking bracket can clamp the cross bar of the limiting hanging frame to position its height, so as to ensure that the driven gear is always engaged with the driving gear.

[0019] 6. The nozzles on the two first main pipes are respectively located on both sides of the inner cavity of the pickling tank and face the duck egg wire rack. When spraying, the coverage range is wide, which is beneficial to improving the uniformity of the brine concentration in the pickling tank.

[0029] Now, embodiments of the present invention will be described with reference to the accompanying drawings.

[0030] Embodiment

[0031] The specific embodiments of the present invention are as follows Figures 1 to 7 As shown, an intelligent pickling system for salted duck eggs includes a pickling tank 1. An aeration device 2 is provided at the bottom of the inner cavity of the pickling tank 1, and a brine spraying device 7 communicating with the bottom of the pickling tank 1 is provided in the upper part of the inner cavity of the pickling tank 1. A rotary drive assembly 5 is provided on the pickling tank 1. The rotary drive assembly 5 includes a rotary motor 51 and a driving gear 52 that are linked. The rotary motor 51 is installed on the outer side wall of the pickling tank 1, and the driving gear 52 is located in the inner cavity of the pickling tank 1 and the two are rotationally matched. The intelligent pickling system for salted duck eggs further includes a duck egg grid frame 3 that can be placed in the pickling tank 1. Both ends of the duck egg grid frame 3 are rotatably connected to limit hanging brackets 6, and the limit hanging brackets 6 are detachably matched with the pickling tank 1. One end of the duck egg grid frame 3 is also fixedly connected with a driven gear 4, and the driven gear 4 meshes with the driving gear 52.

[0032] The duck egg grid frame 3 includes a first outer frame 33 and a second outer frame 34. One side of the two is rotatably connected through a first hinge 36, and the other ends of the two are connected through a first locking structure. In this embodiment, the first locking structure includes a first extension plate 331 connected to one end of the first outer frame 33, and also includes a second extension plate 341 connected to one end of the second outer frame 34. The first extension plate 331 and the second extension plate 341 are connected through a first locking bolt 37 and a first nut.

[0033] A first net plate 31 is connected inside a first outer frame 33. A plurality of first porous cover bodies 311 are provided on the first net plate 31. A second net plate 32 is connected inside a second outer frame 34. A plurality of second porous cover bodies 321 are provided on the second net plate 32. The first porous cover bodies 311 and the second porous cover bodies 321 are arranged opposite to each other. When the positions of the first extension plate 331 and the second extension plate 341 are locked by a first locking bolt 37 and a first nut, the first net plate 31 and the second net plate 32 are parallel to each other and their positions are relatively fixed. The first porous cover bodies 311 and the second porous cover bodies 321 are respectively used to cover both ends of the duck eggs 9, so as to limit the duck eggs 9. The duck egg accommodation space jointly formed between the first porous cover bodies 311 and the second porous cover bodies 321 is slightly larger than the outer contour of the duck eggs 9, and the gap between the two is in the range of 1-2 mm, ensuring that when the aeration device 2 aerates, the duck eggs 9 can vibrate slightly between the first porous cover bodies 311 and the second porous cover bodies 321. A plurality of through holes through which liquid can pass are provided on each net plate and the porous cover bodies, so that the brine in the pickling tank 1 can fully contact with the salted eggs 9. When loading and unloading the duck egg grid 3 outside the pickling tank, the second outer frame 34 can be placed on the tabletop, while the driven gear 4 is suspended outside the edge of the tabletop. In addition, the bottom surface of the second outer frame 34 is lower than the lower end of the second porous cover body 321, so as to ensure that the second outer frame 34 is stably placed on the tabletop.

[0034] First rotating shafts 35 are provided in the middle of both ends of the second outer frame 34. A driven gear 4 is connected to one of the first rotating shafts 35. The driven gear 4 is located above the driving gear 52. The two first rotating shafts 35 are respectively rotatably connected to the limiting hanging frames 6 on both sides.

[0035] The limiting hanging frame 6 includes a cross bar 61, a limiting block 62, and a longitudinal hanging frame 63 connected in sequence. The first rotating shaft 35 of the second outer frame 34 is rotatably connected to the longitudinal hanging frame 63. The outer side wall of the limiting block 62 protrudes from the outer side wall of the cross bar 61. A guiding track 11 is provided on the inner side wall of the pickling tank 1. The longitudinal hanging frame 63 is in sliding fit with the guiding track 11 up and down. During operation, two persons respectively lift the cross bars 61 of the two limiting hanging frames 6 from both sides, move the duck egg grid 3 into the pickling tank 1 from top to bottom, and at the same time let the longitudinal hanging frames 63 on both sides slide down along the guiding track 11 until the driven gear 4 meshes with the driving gear 52.

[0036] Both sides of the pickling pool 1 are connected with locking brackets 8, and the locking brackets 8 are adapted to the crossbar 61. The locking bracket 8 includes a swing frame 82 and a fixed frame 81 arranged at the upper and lower sides respectively, and the fixed frame 81 is connected to the side wall of the pickling pool 1. One side of the swing frame 82 and the fixed frame 81 is rotatably connected by a second hinge 83, and the other sides of the two are connected by a second locking structure. A first pressing groove 821 is provided on the swing frame 82, and a second pressing groove 811 is provided on the fixed frame 81. First, the crossbar 61 of the limit hanger 6 is placed on the second pressing groove 811 with the opening facing upward, and then the swing frame 82 is rotated to buckle above the crossbar 61, and the first pressing groove 821 and the second pressing groove 811 together clamp the crossbar 61 in the middle. Among them, the second locking structure includes a second locking bolt 84 and a second nut. The second locking bolt 84 passes through one end of the swing frame 82 and the fixed frame 81 and is connected to the second nut, so as to lock the relative positions of the swing frame 82 and the fixed frame 81, thereby preventing the cross bar 61 from falling out; one end of the limit block 62 is pressed against the outside of the swing frame 82 and the fixed frame 81, playing a limiting role, preventing the cross bar 61 from shaking along its length direction, and ensuring that the driven gear 4 is meshed with the driving gear 52.

[0037] The salt water spraying device 7 includes two first main pipes 72, each of which is connected to a plurality of nozzles 71 arranged along its length direction. The nozzles 71 on the two first main pipes 72 are respectively located on both sides of the inner cavity of the pickling pool 1 and facing the egg grid 3, and the height of the nozzles 71 is higher than the liquid level in the pickling pool. A drain pipe 12 is connected to the bottom of the pickling pool 1, and an electric control valve 75 is connected to the drain pipe 12. The electric control valve 75 is connected to the two first main pipes 72 through a return pipe 73, and a water pump 74 is connected to the return pipe 73. When the water pump 74 is working, the salt water is pumped out from the pickling pool 1, and the salt water enters the first main pipe 72 through the return pipe 73, and is sprayed from the nozzle 71 to re-enter the liquid surface in the pickling pool 1, so that the concentration of the upper and lower layers of the salt water in the pickling pool 1 tends to be consistent.

[0038] The aeration device 2 includes an aeration pump 24, a second main pipeline 23, a plurality of aeration branches 22 and a plurality of aeration nozzles 21 connected in sequence along the gas flow direction, and the aeration nozzles 21 are located at the bottom of the inner cavity of the pickling pool 1. The aeration pump 24 is installed outside the pickling pool 1, and the aeration nozzles 21 are evenly distributed at the bottom of the inner cavity of the pickling pool 1, and the aeration nozzles 21 spray upward. When the aeration nozzles 21 spray upward, the air flow stirs the salt water upward, and at the same time, in conjunction with the spraying of the salt water spraying device 7 and the rotation of the duck egg grid 3, the salt water in various places in the pickling pool 1 can be mixed evenly and have a consistent concentration.

[0039] In addition, the aeration pump 24 of the aeration device 2, the electric control valve 75 and the water pump 74 of the brine spraying device 7, and the rotation motor 51 of the rotation drive assembly 5 are all electrically connected to the controller. The controller adjusts the flow rate and frequency of the bubbles emerging from the aeration nozzles 21 by controlling the aeration pump 24, adjusts the rotation speed, direction, and the interval time of each rotation of the duck egg grid 3 by controlling the rotation motor 51, and adjusts the circulation frequency and spraying intensity of the nozzles 71 by controlling the water pump 74.

[0040] In this solution, the intelligent pickling method for salted duck eggs is as follows:

[0041] First, expand the first outer frame 33 and the second outer frame 34 of the duck egg grid 3, place the duck eggs 9 into the duck egg grid 3, and then close the duck egg grid 3. Move the duck egg grid 3 into the pickling tank 1 filled with brine and submerge it below the brine liquid level until the driven gear 4 meshes with the driving gear 52, and then lock the cross bar 61 of the limit hanger 6 through the locking bracket 8. The rotation drive assembly 5 is started, and the duck egg grid 3 is driven to rotate in the brine through the linkage between the driven gear 4 and the driving gear 52. Meanwhile, the aeration device 2 agitates the brine at the bottom of the pickling tank 1 through aeration, and at the same time, the brine spraying device 7 pumps out the brine at the bottom of the pickling tank 1 and sprays it back into the pickling tank 1 to keep the brine concentration in the pickling tank 1 uniform.

[0042] During the pickling process, the salt concentration in the pickling tank 1 is corrected by adding salt to ensure that the salt concentration of the pickling material in the pickling environment is consistent, which is beneficial to the uniform ripening of the salted egg yolks and improves the penetration. By means of aeration, the static pickling of salted duck eggs is changed to dynamic pickling. Aeration can cause slight vibrations of the salted duck eggs during pickling, so that even when the egg yolks sink to the bottom, it is not easy to stick to the shell. This can improve the problem of the shape of the egg yolks affected by sinking to the bottom, and also make it easier to separate the egg yolks from the eggshells, thereby improving production efficiency.

[0043] The present invention has been described in combination with the best embodiments, but the present invention is not limited to the disclosed embodiments above, and should cover various modifications and equivalent combinations based on the essence of the present invention.
