[0018] The present application is further described in detail below in conjunction with the accompanying drawings.

[0019] The present application embodiment provides a pickled vegetable production intermediate processing equipment, Figure 1 -Attached Figure 6 , comprising a columnar cylinder 100, the cylinder 100 is open at the top and closed at the bottom, the cylinder 100 has a cylindrical working chamber 101 inside, and the inner wall of the cylinder 100 is rough; The bottom of the cylinder 100 is rotatably connected with a rotating shaft 30, the central axis of the rotating shaft 30 is colinear with the central axis of the cylinder 100 and the working chamber 101, the bottom of the rotating shaft 30 passes through the bottom of the cylinder 100 and extends out of the cylinder 100, and one end of the rotating shaft 30 extending out of the cylinder 100 is installed with a driving device 40 for driving the rotating shaft 30 to rotate, the top of the rotating shaft 30 passes through the bottom of the cylinder 100 and extends into the working chamber 101, and the rotating shaft 30 extends into the cylinder 100. The outer side of the top of the rotating shaft 30 is installed with a base 20, and the base 20 can rotate in the working chamber 101; The base 20 has a feed portion 21, an extrusion portion 22 and two diameter-reducing portions 23. The outer side surfaces of the feed portion 21, the extrusion portion 22 and the two diameter-reducing portions 23 are perpendicular to the two end surfaces of the base 20. The feed portion 21 is formed by the base 20 being recessed toward the center. The two diameter-reducing portions 23 are respectively a first diameter-reducing portion 23 and a second diameter-reducing portion 23. The first diameter-reducing portion 23 is located on a side of the extrusion portion 22 close to the feed portion 21, and the second diameter-reducing portion 23 is located on a side of the extrusion portion 22 away from the feed portion 21. The side surface of the feed portion 21 intersects with the side surface of the first diameter-reducing portion 23. The end of the second diameter-reducing portion 23 away from the extrusion portion 22 has a discharge area 107, the distance between the side of the diameter-reducing portion 23 and the inner wall of the cylinder 100 gradually decreases in the circumferential direction close to the extrusion portion 22, the minimum distance between the side of the extrusion portion 22 and the inner wall of the cylinder 100 is smaller than the minimum distance between the side of the diameter-reducing portion 23 and the inner wall of the cylinder 100, the minimum distance between the side of the feeding portion 21 and the inner wall of the cylinder 100 is greater than the minimum distance between the side of the diameter-reducing portion 23 and the inner wall of the cylinder 100, and the outer side surfaces of the feeding portion 21, the extrusion portion 22 and the two diameter-reducing portions 23, that is, the outer side surface of the base 20 are rough; The discharge area 107 is located in the working chamber 101 of the cylinder 100. The discharge area 107 is the area formed by the outer side surface of the second diameter-reducing portion 23 and the inner side surface of the cylinder 100. The outer side surface of the feeding portion 21 and the inner side surface of the cylinder 100 form the feeding area 102. The first diameter-reducing portion 23 and the inner side surface of the cylinder 100 form the first diameter-reducing area 103. The extrusion portion 22 and the inner side surface of the cylinder 100 form the extrusion area 105. The second diameter-reducing portion 23 and the inner side surface of the cylinder 100 form the second diameter-reducing area 106. The first diameter-reducing area 103 is directed to the feeding area 102 in an annular circle. When the circumferential direction is the positive direction, starting from the feed zone 102 and extending in the reverse direction, there are the feed zone 102, the first diameter-changing zone 103, the extrusion zone 105, the second diameter-changing zone 106 and the discharge zone 107. The feed zone 102, the first diameter-changing zone 103, the extrusion zone 105, the second diameter-changing zone 106 and the discharge zone 107 are connected in sequence. When the base body 20 is rotating, the positions of the feed zone 102, the first diameter-changing zone 103, the extrusion zone 105, the second diameter-changing zone 106 and the discharge zone 107 inside the cylinder 100 change with the positive direction, but the positional relationship therebetween remains unchanged.

[0020] The following is a further introduction based on specific usage scenarios.

[0021] When in use, the operator turns on the driving device 40, and the driving device 40 drives the base 20 to rotate in the working chamber 101 inside the cylinder 100 through the rotating shaft 30. The rotation direction of the base 20 is the positive direction. At this time, the operator can continuously add pickled vegetable heads to the feeding area 102. The pickled vegetable heads move in the opposite direction relative to the base 20 on the outside of the base 20, and then clean water is injected into the cylinder 100.

[0022] The pickled vegetable heads initially entering the cylinder 100 will gather outside the feeding portion 21 and in the feeding area 102. The width of the feeding area 102 gradually decreases in the opposite direction. With the rotation of the base 20 and the subsequent addition of the pickled vegetable heads, the pickled vegetable heads close to the first diameter-changing area 103 are forced to enter the first diameter-changing area 103. The width of the first diameter-changing zone 103, that is, the distance between the first diameter-changing portion 23 and the inner wall of the cylinder 100, gradually decreases in the reverse direction. As the base 20 rotates, the pickled vegetable heads will be gradually squeezed, causing the high-salt water inside the pickled vegetable heads to be gradually squeezed out. After the pickled vegetable heads reach the end of the first diameter-changing zone 103 away from the feeding zone 102, they will enter the squeezing zone 105. The maximum width of the squeezing zone 105 is smaller than the minimum width of the first diameter-changing zone 103. The pickled vegetable heads are further squeezed and desalted by the squeezing portion 22 in the squeezing zone 105. As the base 20 rotates, the pickled vegetable heads located inside the extrusion portion 22 will enter the second diameter-changing zone 106, and the width of the second diameter-changing zone 106 will gradually increase in the opposite direction. In this way, the pickled vegetable heads that have been desalted for the second time will gradually absorb water and restore their shape in the second diameter-changing zone 106, and the pores inside the pickled vegetable heads that originally stored high-salt water will be filled with clean water, thereby forming desalination. As the base 20 rotates, the pickled vegetable heads inside the second diameter-changing zone 106 will enter the discharging zone 107, and the operator can take away the pickled vegetable heads in the discharging zone 107.

[0023] From the perspective of the overall desalting sequence of the pickled cabbage heads, after entering the feeding area 102, the pickled cabbage heads pass through the first diameter-changing area 103 and the extrusion area 105 in sequence for desalting. After desalting, the pickled cabbage heads move inside the second diameter-changing area 106 to absorb water to complete desalting. After desalting, the operator can take away the pickled cabbage heads. When the operator takes away the pickled cabbage heads, there is no need to stop the rotation of the base 20. The pickled cabbage heads can also be added continuously during the operation of the equipment, so that the desalter can work continuously without the operator having to stop and wait during the process of taking and discharging materials, which significantly improves the overall desalting efficiency.

[0024] It should be understood that the positive direction in the embodiment of the present application is the annular circumferential direction of the first diameter-changing zone 103 pointing to the feeding zone 102. When the rotation direction of the base 20 is the positive direction, the pickled vegetable heads move in the opposite direction relative to the base 20 on the outer side of the base 20. Under the rotation of the base 20 and the subsequent squeezing of the pickled vegetable heads, the pickled vegetable heads near the first diameter-changing zone 103 will have a tendency to move in the direction of the first diameter-changing zone 103, that is, in the opposite direction. After the first diameter-changing portion 23 contacts the pickled vegetable heads, the pickled vegetable heads tend to rotate, and the direction of the rotation trend of the pickled vegetable heads is opposite to the rotation direction of the base 20. The inner wall of the cylinder 100 contacts the pickled vegetable heads to provide friction for the pickled vegetable heads to prevent relative sliding between the pickled vegetable heads and the inner wall of the cylinder 100, thereby forming the first diameter-changing portion 23 of the first diameter-changing zone 103 and the inner wall of the cylinder 100 to bite the pickled vegetable heads and move them in the opposite direction relative to the base 20.

[0025] It can be found from the above description that there is less relative sliding between the pickled vegetable heads and the base 20 and the inner wall of the cylinder 100, which also means that when the base 20 rotates, the pickled vegetable heads will rotate relatively. In this way, the pickled vegetable heads rotate during the extrusion process, so that the pickled vegetable heads can be evenly extruded and desalted, thereby increasing the desalination amount of the pickled vegetable heads during a single extrusion, thereby reducing the desalination times of the pickled vegetable heads, thus further improving the overall desalination efficiency of the pickled vegetable heads.

[0026] It can be found that in the embodiment of the present application, the first diameter-changing zone 103, the extrusion zone 105 and the second diameter-changing zone 106 are fed at a single time, that is, the first diameter-changing zone 103, the extrusion zone 105 and the second diameter-changing zone 106 can enter one after another but not in parallel, and each pickled vegetable head can achieve gradual extrusion in the first diameter-changing zone 103 and secondary extrusion in the extrusion zone 105. Compared with the stacking extrusion method in the prior art, the pickled vegetable heads in the embodiment of the present application have better extrusion effect and better desalination effect, thereby reducing the number of desalination times, the number of processes and the time of the pickled vegetable heads, and further improving the overall desalination efficiency of the pickled vegetable heads. On this basis, the clean water inside the cylinder 100 can directly wrap each pickled vegetable head that is being desalted and relaxed, so that the pickled vegetable heads can be desalted more thoroughly, thereby reducing the number of desalination times, the number of processes and the time of the pickled vegetable heads, and further improving the overall desalination efficiency of the pickled vegetable heads.

[0027] See attached Figure 2 -Attached Figure 6 As a feasible specific implementation method of the embodiment of the present application, the end of the feeding part 21 away from the reducing part 23 intersecting with its side surface has a blocking part 24, and the blocking part 24 is used to separate the first reducing part 23 and the end of the second reducing part 23 away from the extrusion part 22, that is, to divide the feeding area 102 and the discharging area 107. The side of the blocking part 24 intersects with the side of the feeding part 21. The setting of the blocking part 24 can effectively prevent the desalted pickled vegetable heads from re-entering the feeding area 102, making it convenient for operators to pick up the pickled vegetable heads or for the pickled vegetable heads to leave the feeding area 102 on their own.

[0028] See attached Figure 6 -Attached Figure 8 As a feasible specific implementation method of the embodiment of the present application, a feed pad 50 is also installed on the outer side of the base 20. The feed pad 50 is fixedly connected to the side of the feed part 21. The height of the feed pad 50 gradually decreases in the direction away from the feed part 21. The feed pad 50 is located inside the feed area 102. When the operator feeds the material into the feed area 102, the pickled vegetable heads tend to move toward the first diameter-changing area 103. A pickled vegetable head close to the first diameter-changing area 103 is squeezed by the subsequent pickled vegetable heads and will be smoothly bitten into the first diameter-changing part 23 and the inner wall of the cylinder 100 to achieve desalination.

[0029] See attached Figure 6 -Attached Fig. 9 As a feasible specific implementation method of the embodiment of the present application, a discharging pad 60 is provided in the discharging area 107, and the discharging pad 60 is fixedly connected to the base 20. The top of the discharging pad 60 has an inclined surface, and the distance between the top inclined surface of the discharging pad 60 and the bottom of the cylinder 100 gradually increases in the circumferential direction away from the extrusion portion 22. In this way, the pickled vegetable heads entering the discharging area 107 will be continuously lifted along the discharging pad 60, thereby realizing autonomous separation from the discharging area 107, without the need for operators to pick them out, and further improving the overall desalination efficiency.

[0030] The intersection of the top inclined surface of the discharge pad 60 and the bottom surface of the discharge pad 60 is a sharp edge 61. The sharp edge 61 is on the plane where the bottom of the base 20 is located. The setting of the sharp edge 61 can better lift the pickled vegetable heads, thereby ensuring that the pickled vegetable heads can smoothly enter the top of the discharge pad 60.

[0031] The bottom of the cylinder 100 is provided with an annular bottom plate and a conical polymer body 71. The polymer body 71 is hollow inside and open at the top. The diameter of the internal space of the polymer body 71 gradually decreases as it extends away from the cylinder 100. The internal space of the polymer body 71 is connected to the working chamber 101. The outer side of the top of the polymer body 71 is fixedly connected to the inner side of the annular bottom plate. The bottom of the polymer body 71 is connected with a drain pipe 72. The setting of the polymer body 71 can make impurities in the extrusion process gather in the polymer body 71, thereby reducing the interference of insoluble impurities on the extrusion process. The drain pipe 72 is opened at the bottom of the polymer body 71, which can also facilitate the discharge of brine and impurities. In the process of draining, the desalination work is not affected, and the desalter does not need to be stopped and waited, thereby improving the overall desalination efficiency of the pickled vegetables.

[0032] On this basis, the sharp edge 61 of the discharge pad block 60 deviates from the radial direction of the cylinder 100, and the sharp edge 61 of the discharge pad block 60 deviates from the end close to the rotating shaft 30 in the direction away from the extrusion portion 22. In this way, when impurities sink to the bottom, the sharp edge 61 will scoop up the impurities. As the base 20 rotates, the rotating sharp edge 61 of the discharge pad block 60 will push the impurities into the aggregate body 71 for easy discharge.

[0033] As a feasible specific implementation of the embodiment of the present application, the base 20 also has two contraction parts 25, the contraction part 25 is between the extrusion part 22 and the diameter-reducing part 23, the two contraction parts 25 are distributed on both sides of the extrusion part 22, the side surfaces of the two contraction parts 25 intersect with the side surfaces of the two diameter-reducing parts 23 respectively, the contraction part 25 is formed by the base 20 being concave in the direction of the rotation axis 30, the distance between the side surface of the contraction part 25 and the inner wall of the cylinder 100 increases first and then decreases in the direction close to the extrusion part 22, and a concave area 104 is formed between the outer side surface of the contraction part 25 and the inner wall of the cylinder 100, and the concave area 104 includes a tightening area 109 and a relaxing area 108; For the convenience of description, the depressed area 104 between the extrusion area 105 and the first diameter-changing area 103 is defined as the first depressed area 104, and the depressed area 104 between the extrusion area 105 and the second diameter-changing area 106 is defined as the second depressed area 104. The depressed area 104 includes a relaxation area 108 and a tightening area 109. The width of the relaxation area 108, that is, the distance between the outer side surface of the contraction portion 25 in the relaxation area 108 and the inner wall of the cylinder 100 gradually decreases in the positive direction and gradually increases in the reverse direction. The width of the tightening area 109, that is, the distance between the outer side surface of the contraction portion 25 in the tightening area 109 and the inner wall of the cylinder 100 gradually increases in the positive direction and gradually decreases in the reverse direction. The relaxation area 108 and the tightening area 109 of the first depressed area 104 are respectively The diameter zone 103 is connected to the extrusion zone 105, and the relaxation zone 108 and the tightening zone 109 of the second depression zone 104 are respectively connected to the extrusion zone 105 and the second diameter-changing zone 106. In this way, when the base 20 rotates, the pickle heads entering the first depression zone 104 from the first diameter-changing zone 103 first absorb water and relax in the relaxation zone 108, and then are compressed again in the tightening zone 109. The pickle heads entering the second depression zone 104 from the extrusion zone 105 first absorb water and relax in the relaxation zone 108, and then are compressed again in the tightening zone 109. As a result, the pickle heads are relaxed and contracted multiple times during one movement, thereby improving the desalination effect of the pickle heads, reducing the number of desalination processes, the number of processes and the time of the pickle heads, and further improving the overall desalination efficiency of the pickle heads.

[0034] On this basis, refer to the attached Figure 7 -Attached Fig.10A spray pipe 70 is installed on the base 20, and the spray head of the spray pipe 70 is in the contraction part 25. The spray head of the spray pipe 70 is located on the side of the contraction part 25 away from the inner wall of the cylinder 100, and the spray head of the spray pipe 70 faces the inner wall of the cylinder 100. In this way, when the spray pipe 70 is working, both of the two recessed areas 104 have clean water with low salinity. When the pickled vegetable heads enter the two recessed areas 104 to discharge salt and absorb water, the desalination effect of the pickled vegetable heads can be improved. In addition, when spraying, the spray pipe 70 can directly spray the pickled vegetable heads that are discharging salt and absorbing water, and can maintain the low salinity of the water in the recessed areas 104, thereby improving the utilization efficiency of clean water.

[0035] In some possible implementations of the embodiments of the present application, the driving device 40 includes a reduction motor 41. In the assembled state, the position of the reduction motor 41 is consistent with the position of the cylinder 100, and the installation position of the reduction motor 41 is not limited. A driving wheel 42 is installed on the main shaft of the reduction motor 41, and a transmission belt 43 is sleeved on the outer side of the driving wheel 42. The bottom of the rotating shaft 30 extends out of the cylinder 100, and a driven wheel 44 is installed on the end of the rotating shaft 30 extending out of the cylinder 100. The transmission belt 43 is frictionally connected with the driven wheel 44, that is, the transmission belt 43 is sleeved on the outer side of the driving wheel 42 and the driven wheel 44. When the reduction motor 41 rotates, the driving wheel 42 drives the rotating shaft 30 to rotate through the transmission belt 43 and the driven wheel 44. In actual use, there are multiple belt grooves on the outer sides of the driving wheel 42 and the driven wheel 44, and there are also multiple transmission belts 43. The reduction motor 41 can be connected to the mains for power.

[0036] The rotating shaft 30 is sealed and connected to the bottom of the cylinder 100. In actual use, a water seal 32 can be set at the rotating connection between the rotating shaft 30 and the cylinder 100. In the working state, the water seal 32 is at the bottom of the inner cavity of the cylinder 100, and has sufficient water pressure to maintain the formation of a water film on the water seal 32, thereby maintaining the sealed connection between the rotating shaft 30 and the cylinder 100. Of course, the water seal 32 can also be set at the bottom of the polymer body 71 for adaptation.

[0037] The positions of the rotating shaft 30 and the base 20 remain basically unchanged in the connected state. Except for a slight axial movement, there is basically no radial mutual displacement between the base 20 and the rotating shaft 30. In the embodiment of the present application, a spline groove 26 can be opened in the middle of the base 20, and a fixed spline 31 can be set on the outside of the part of the rotating shaft 30 that extends into the working chamber 101 of the cylinder 100. During assembly, the fixed spline 31 on the outside of the rotating shaft 30 extends into the spline groove 26 of the base 20 to realize the connection between the rotating shaft 30 and the base 20.

[0038] In some possible implementations of the embodiments of the present application, refer to the attached Fig.11 and attached Fig.12An annular limit groove 110 can be opened at the bottom of the inner cavity of the cylinder 100, and an arc-shaped limit slider 27 is provided at the bottom of the base 20. In the assembled state, the limit slider 27 extends into the limit groove 110 and can slide in the limit groove 110. In this way, when the base 20 rotates, the arc-shaped outer side surface and the arc-shaped inner side surface of the arc-shaped limit slider 27 can both contact the inner wall of the limit groove 110 to reduce the radial movement of the base 20. Of course, when there is a polymer body 71 at the bottom of the cylinder 100, the limit groove 110 can be located on the outside of the top of the polymer body 71.

[0039] In some possible implementations of the embodiments of the present application, refer to the attached Fig.13 and attached Fig.14 A packaging cover 80 is installed on the top of the base 20. In the assembled state, the packaging cover 80 is relatively fixed to the base 20, and the packaging cover 80 and the cylinder 100 can rotate relatively. The packaging cover 80 blocks the top opening of the cylinder 100. When the base 20 extrude materials and rotates inside the cylinder 100, the setting of the packaging cover 80 can prevent the pickled vegetable head from escaping from the established extrusion and desalination path and leaving the cylinder 100. The packaging cover 80 is provided with a feed inlet 81 and a discharge port 82. The feed inlet 81 is located at the top of the outer space of the feed inlet 21 of the cylinder 100, and the discharge port 82 is located at the top of the outer space of the feed inlet 21 of the cylinder 100. 82 is at the top of the outer space of the reducing portion 23. In the working state, undesalted pickled vegetable heads enter the cylinder 100 from the feed port 81, and the desalted pickled vegetable heads leave the cylinder 100 from the discharge port 82. A discharge channel 83 is provided on the top of the packaging cover 80. The inner space of the discharge channel 83 is connected to the discharge port 82, and the outlet of the discharge channel 83 is far away from the discharge port 82. When the packaging cover 80 is rotating, the desalted pickled vegetable heads entering the discharge channel 83 are thrown out under the action of the centrifugal force generated by the rotation of the packaging cover 80.

[0040] The embodiment of the present application also provides a method for intermediate processing of pickled vegetables production, using the aforementioned intermediate processing equipment for pickled vegetables production, comprising: Add pickled vegetable heads into the cylinder 100. The pickled vegetable heads are added to the area between the feeding part 21 and the inner wall of the cylinder 100. The pickled vegetable heads are added continuously. Turn on the driving device to drive the base body 20 to rotate, so that the base body 20 rotates relative to the pickled vegetable head; The pickled vegetable heads are continuously extruded through the base 20 and enter the discharging area 107; The squeezed pickled vegetable heads in the discharging area 107 are taken out, and the base body does not stop rotating during the process of taking out the pickled vegetable heads.

[0041] The overall desalination efficiency is improved by not stopping the equipment when adding and removing pickled vegetables.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
