[0021] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0023] The following reference Figures 1 to 7 This application describes an apparatus for preparing jujube pulp according to some embodiments.

[0024] Example A device for preparing jujube pulp includes a first shearing and stirring mechanism 1, a connecting pipe 2, a second shearing and stirring mechanism 3, and a support frame 4. The connecting pipe 2 is located at the bottom of the first shearing and stirring mechanism 1, with one end fixedly connected to the bottom of the first shearing and stirring mechanism 1. The second shearing and stirring mechanism 3 is located at the bottom of the connecting pipe 2, with its top fixedly connected to the end of the connecting pipe 2 away from the first shearing and stirring mechanism 1. The first shearing and stirring mechanism 1 and the second shearing and stirring mechanism 3 are connected through the connecting pipe 2. The support frame 4 is located at the bottom of the first shearing and stirring mechanism 1 and the second shearing and stirring mechanism 3, and is used to support the first shearing and stirring mechanism 1 and the second shearing and stirring mechanism 3.

[0025] According to the jujube pulp preparation apparatus of this embodiment, the processed jujube raw material is first placed into the first shearing and stirring mechanism 1, and the first shearing and stirring mechanism 1 is turned on to shear and stir the jujube raw material. After the shearing and stirring of the first shearing and stirring mechanism 1 is completed, a coarse pulp is obtained. Then, the coarse pulp in the first stirring mechanism 1 enters the second shearing and stirring mechanism 3 through the connecting pipe 2. At this time, the first shearing and stirring mechanism 1 is turned off, and the second shearing and stirring mechanism 3 is turned on to repeatedly shear and stir the coarse pulp to obtain the desired jujube pulp. Finally, the obtained jujube pulp is taken out from the second shearing and stirring mechanism 3. The support frame 4 is set to effectively support the first shearing and stirring mechanism 1 and the second shearing and stirring mechanism 3.

[0026] As an optional implementation of this embodiment, the first shearing and stirring mechanism 1 includes a first stirring tank 11, a solenoid valve 12, a first motor 13, a first stirring shaft 14, a first shearing and stirring assembly 15, a driving bevel gear 16, multiple driven bevel gears 17, and multiple second shearing and stirring assemblies 18; wherein, the top of the first stirring tank 11 is provided with a switchable first feed inlet 111, the bottom of the first stirring tank 11 has a conical structure that is wider at the top and narrower at the bottom, and the bottom of the first stirring tank 11 is provided with a first discharge outlet 112, which is connected to one end of the connecting pipe 2; the solenoid valve 12 is disposed at the first discharge outlet 112, and the solenoid valve is used to control the opening and closing of the first discharge outlet 112; the first motor 13 is disposed at the top of the first stirring tank 11; the first... A stirring shaft 14 is vertically installed inside a first stirring tank 11. One end of the first stirring shaft 14 passes through the top of the first stirring tank 11 and is fixedly connected to the output shaft of a first motor 13. The first stirring shaft 14 is rotatably connected to the top of the first stirring tank 11. A first shearing stirring assembly 15 is installed inside the first stirring tank 11 and is sleeved on the first stirring shaft 14. A driving bevel gear 16 is fixedly sleeved on the first stirring shaft 14, and multiple driven bevel gears 17 are evenly meshed and connected to the driving bevel gear 16. Multiple second shearing stirring assemblies 18 correspond one-to-one with the driven bevel gears 17. One end of a second shearing stirring assembly 18 is fixedly connected to the corresponding driven bevel gear 17, and the other end is rotatably connected to the inside of the first stirring tank 11.

[0027] It should be noted that, firstly, the first feed inlet 111 is opened, and the raw material of jujube is put into the first mixing tank 11 through the first feed inlet 111, and then the first feed inlet 111 is closed; next, the first motor 13 is turned on, and the rotation of the first motor 13 drives the first stirring shaft 14 to rotate inside the first mixing tank 11. The first shearing stirring assembly 15 is sleeved on the first stirring shaft 14, so when the first stirring shaft 14 rotates, it drives the first shearing stirring assembly 15 on the first stirring shaft 14 to rotate around the first stirring shaft 14; thereby realizing the rotation of the first shearing stirring assembly. 15. Shearing and stirring of the raw material of *Ziziphus jujuba*; simultaneously, since the driving bevel gear 16 is fixedly sleeved on the first stirring shaft 14, the rotation of the first stirring shaft 14 will also drive the rotation of the driving bevel gear 16, and multiple driven bevel gears 17 are evenly meshed and connected to the driving bevel gear 16. The second shearing and stirring assembly 18 corresponds one-to-one with the driven bevel gears 17; one end of the second shearing and stirring assembly is fixedly connected to the corresponding driven bevel gear 17, and the other end is rotatably connected to the inside of the first stirring box 11. Therefore, when the driving bevel gear 16 rotates, the shearing and stirring of the raw material is also driven by the driving bevel gear 16. At the same time, the driven bevel gear 17 rotates, which in turn drives the second shearing and stirring assembly 18 to rotate, thus enabling the second shearing and stirring assembly 18 to shear and stir the raw material of jujube. Ultimately, the first shearing and stirring assembly 15 and the second shearing and stirring assembly 18 simultaneously shear and stir the raw material of jujube, improving the processing efficiency of jujube. Meanwhile, the shearing and stirring direction of the first shearing and stirring assembly 15 is a rotational shearing and stirring around the first stirring shaft 14, that is, the plane of rotation is perpendicular to the axis of the first stirring shaft 14, while the second shearing and stirring assembly 18... The transmission between the moving bevel gear 16 and the driven bevel gear enables rotation, meaning the rotating surface is parallel to the axis of the first stirring shaft 14. Therefore, the first shearing and stirring assembly 15 and the second shearing and stirring assembly 18 shear and stir the raw material of jujube from different directions, greatly improving the processing efficiency. After shearing and stirring the raw material of jujube, a coarse pulp is obtained. At this time, the control solenoid valve 12 opens the first discharge port 112 at the bottom of the first stirring box 11, and the coarse pulp enters the connecting pipe 2 through the first discharge port 112, and finally enters the second shearing and stirring mechanism 3.

[0028] As an optional implementation of this embodiment, the first shearing and stirring assembly 15 includes a fixing ring 151 and a plurality of first shearing and stirring units 152; wherein, the fixing ring 151 is fixedly sleeved on the first stirring shaft 14; the plurality of first shearing and stirring units 152 are evenly arranged around the outside of the fixing ring 151, and one end of the plurality of first shearing and stirring units 152 is fixedly connected to the outside of the fixing ring 151.

[0029] It should be noted that when the first stirring shaft 14 rotates, it first drives the fixed ring 151 fixedly sleeved on the first rotating shaft 14 to rotate. Since multiple first shearing and stirring units 152 are evenly arranged around the outside of the fixed ring 151 and fixedly connected to the outside of the fixed ring 151, when the fixed ring 151 rotates, it drives multiple first shearing and stirring units 152 to rotate around the first stirring shaft 14, thereby performing shearing and processing of the jujube raw material through the first shearing and stirring units 152.

[0030] As an optional implementation of this embodiment, the first shearing and stirring unit 152 includes a main blade 1521 and a plurality of secondary blades 1522; wherein, one end of the main blade 1521 is fixedly connected to the outside of the fixing ring 151, and the other end is suspended inside the first stirring box 11; the plurality of secondary blades 1522 are symmetrically arranged on the upper and lower sides of the main blade 1521, and the plurality of secondary blades 1522 are fixedly connected to the main blade 1521.

[0031] It should be noted that when the fixed ring 151 rotates, the main blade 1521 in the first shearing and stirring unit 152 rotates with the fixed ring 151 to achieve shearing and stirring of the jujube raw material. At the same time, since multiple auxiliary blades 1522 are symmetrically arranged on the upper and lower sides of the main blade 1521 and are fixedly connected to the main blade 1521, when the main blade 1521 rotates, the auxiliary blades 1522 arranged on the upper and lower sides of the main blade 1521 will also rotate around the first rotating axis 14, thereby achieving further shearing and stirring of the jujube raw material.

[0032] As an optional implementation of this embodiment, the second shearing and stirring assembly 18 includes a second stirring shaft 181 and a plurality of rotating blades 182; wherein, one end of the second stirring shaft 181 is fixedly connected to the corresponding driven bevel gear 17, and the other end is rotatably connected to the inner side of the first stirring box 11; the plurality of rotating blades 182 are evenly sleeved on the second stirring shaft 181, and the plurality of rotating blades 182 are all fixedly connected to the second stirring shaft 181.

[0033] It should be noted that when the driving bevel gear 16 rotates, it drives the driven bevel gear 17 to rotate. Since one end of the second stirring shaft 181 is fixedly connected to the corresponding driven bevel gear 17 and the other end is rotatably connected to the inside of the first stirring box 11, the rotation of the driven bevel gear 17 drives the second stirring shaft 181 to rotate. Furthermore, multiple rotating blades 182 are uniformly fixedly mounted on the second stirring shaft 181. Therefore, while the second stirring shaft 181 rotates, it drives the multiple rotating blades 182 on the second stirring shaft 181 to rotate around the second stirring shaft 181, thereby achieving shearing and stirring of the raw material of jujube.

[0034] As an optional implementation of this embodiment, the second shearing and stirring mechanism 3 includes a second stirring tank 31, a second motor 32, a drive shaft 33, a crossbar 34, and two third shearing and stirring components 35; wherein, the second stirring tank 31 has a conical design that is wider at the top and narrower at the bottom, and a second feed inlet 311 is provided at the top of the second stirring tank 31, which is connected to the end of the connecting pipe 2 away from the first shearing and stirring mechanism 1; a second discharge port 312 that can be switched is provided at the bottom of the second stirring tank 31; the second motor 32 is disposed in the second stirring tank 31. 1. Top: The drive shaft 33 is vertically installed on the upper side inside the second mixing tank 31. One end of the drive shaft 33 passes through the top of the second mixing tank 31 and is fixedly connected to the second motor 32. The crossbar 34 is installed at one end of the drive shaft 33 inside the second mixing tank 31. The crossbar 34 is perpendicular to the drive shaft 33. The two ends of the crossbar 34 are symmetrically distributed with respect to the central axis of the drive shaft 33. Two third shearing and stirring components 35 are respectively installed at both ends of the crossbar 34. The two third shearing and stirring components 35 are symmetrically arranged with the central axis of the drive shaft 33 as the axis.

[0035] It should be noted that the coarse slurry prepared by the first shearing and mixing component 1 enters the second mixing tank 31 from the second feed inlet 311 at the top of the second mixing tank 31 after passing through the connecting pipe 2. At this time, the second motor 32 is turned on, and the second motor 32 rotates, driving the transmission shaft 33, which is fixedly connected to the output shaft of the second motor 32, to rotate. The crossbar 34 is located at one end of the transmission shaft 33 inside the second mixing tank 31. The crossbar 34 is perpendicular to the transmission shaft 33, and the two ends of the crossbar 34 are symmetrically distributed with respect to the central axis of the transmission shaft 33. Therefore, when the transmission shaft 33 rotates, it drives the crossbar 34 to rotate around the central axis of the transmission shaft 33. Then, due to the two third shears... The shearing and stirring components 35 are respectively set at both ends of the crossbar 34. The two third shearing and stirring components 35 are symmetrically arranged with the central axis of the transmission shaft 33 as the axis. Therefore, when the crossbar 34 rotates with the central axis of the transmission shaft 33 as the center, it drives the two third shearing and stirring components 35 to rotate with the central axis of the transmission shaft 33 as the center. Finally, the two third shearing and stirring components 35 further stir and shear the coarse pulp. After the further stirring and shearing of the coarse pulp is completed, the desired jujube pulp is obtained. Finally, the second discharge port 312 set at the bottom of the second mixing tank 31 is opened, and the jujube pulp flows out from the second discharge port 312 into the external container, completing the preparation of jujube pulp.

[0036] As an optional implementation of this embodiment, the third shearing and stirring assembly 35 includes a waterproof motor 351, a third stirring shaft 352, and a spiral blade 353; wherein, one end of the waterproof motor 351 is fixedly connected to one end of the crossbar 34; one end of the third stirring shaft 352 is fixedly connected to the output shaft of the waterproof motor 351, and the other end is suspended in the second stirring box 31; the spiral blade 353 is arranged around the side of the third stirring shaft 352, and the spiral blade 353 is fixedly connected to the third stirring shaft 352.

[0037] It should be noted that while the crossbar 34 rotates, the two waterproof motors 351 are turned on. The output shafts of the waterproof motors 351 rotate, driving the third stirring shaft 352 to rotate, which in turn drives the two spiral blades 353 respectively mounted on the two third stirring shafts 352 to rotate. At the same time, as the crossbar 34 rotates, it drives the two third stirring shafts 352 to rotate around the axis of the transmission shaft 33, which in turn drives the two spiral blades 353 respectively mounted on the two third stirring shafts 352 to rotate around the axis of the transmission shaft 33. This achieves the rotation and self-rotation of the two symmetrically arranged spiral blades 353, thereby greatly improving the efficiency of processing coarse slurry.

[0038] As an optional implementation of this embodiment, the first feed inlet 111 includes a first through hole 1111 and a first cover plate 1112; wherein, the first through hole 1111 is disposed on the top of the first mixing tank 11; the first cover plate 1112 is disposed on one side of the first through hole 1111, the first cover plate 1112 is hinged to the top of the first mixing tank 11, and the first cover plate 1112 is used to control the opening and closing of the first through hole 1111.

[0039] It should be noted that after opening the first cover plate 1112, the raw material of jujube is poured into the first mixing box through the first through hole 1111, and then the first cover plate 1112 is closed; then the subsequent processing of the raw material of jujube is completed.

[0040] As an optional implementation of this embodiment, the second discharge port 312 includes a second through hole 3121 and a second cover plate 3122; wherein, the second through hole 3121 is disposed at the bottom of the second mixing tank 31; the second cover plate 3122 is disposed on one side of the second through hole 3121, the second cover plate 3122 is hinged to the bottom side of the second mixing tank 31, and the second cover plate 3122 is used to control the opening and closing of the second through hole 3121.

[0041] It should be noted that after the jujube pulp is prepared in the second mixing tank 31, the second cover plate 3122 is opened, and the jujube pulp in the second mixing tank 31 flows out into the container through the second through hole 3121. After all the jujube pulp has flowed out, the second cover plate 3122 is closed.

[0042] As an optional implementation of this embodiment, the number of second shearing and stirring components 18 is 2 or 3. It should be noted that by setting up two or three second shearing and stirring components, the processing efficiency of jujube raw materials can be improved.

[0043] According to the jujube pulp preparation device of this embodiment, its working process is as follows: First, open the first cover plate 1112 and pour the raw material of jujube into the first mixing box through the first through hole 1111, then close the first cover plate 1112; next, turn on the first motor 13, the first motor 13 rotates and drives the first stirring shaft 14 to rotate inside the first mixing box 11, thereby driving the fixed ring 151 fixedly sleeved on the first rotating shaft 14 to rotate, which in turn drives the multiple main blades 1521 to rotate, as well as the multiple auxiliary blades 1522 set on the upper and lower sides of each main blade 1521 to rotate, realizing the shearing and stirring of the raw material of jujube in the horizontal direction (the plane direction perpendicular to the central axis of the first stirring shaft 14); at the same time, the first stirring shaft 14 in the first mixing box... The rotation inside the mixing tank 11 drives the active bevel gear 16 to rotate, which in turn drives multiple driven bevel gears 17 to rotate. The rotation of the driven bevel gears 17 drives multiple corresponding second stirring shafts 181 to rotate, which in turn drives the rotating blades mounted on the second stirring shafts 181 to rotate, further realizing the vertical shearing and stirring of the jujube raw material (in a plane parallel to the central axis of the first stirring shaft 14); ultimately achieving dual processing of the jujube raw material in both horizontal and vertical directions to obtain coarse pulp; at this time, the first motor 13 is turned off, the solenoid valve 12 is opened, and the solenoid valve 12 is controlled to open the first discharge port 112 at the bottom of the first mixing tank 11, and the coarse pulp passes through... After passing through the first discharge port 112, the material flows through the connecting pipe 2 and then enters the second mixing tank 31 through the second inlet 311 at the top of the second mixing tank 31. At this time, the control solenoid valve closes the first discharge port 112. Then, the second motor 32 and the waterproof motor 351 are turned on. The rotation of the second motor 32 drives the transmission shaft 33, which is fixedly connected to the output shaft of the second motor 32, to rotate. When the transmission shaft 33 rotates, it drives the crossbar 34 to rotate around the central axis of the transmission shaft 33, which in turn drives the two third mixing shafts 352 to rotate around the axis of the transmission shaft 33. This, in turn, drives the two spiral blades 353, which are respectively set on the two third mixing shafts 352, to rotate around the axis of the transmission shaft 33. The center rotates, and since the waterproof motor 351 is also rotating, it drives the third stirring shaft 352 to rotate, which in turn drives the two spiral blades 353 respectively set on the two third stirring shafts 352 to rotate. Finally, the spiral blades 352 rotate around the central axis of the transmission shaft 33 and rotate on their own. Through the rotation of the spiral blades 352 around the central axis of the transmission shaft 33 and their own rotation, the efficiency of coarse pulp processing can be greatly improved. After processing, the final jujube pulp is obtained. Then, the second cover plate 3122 is opened, and the jujube pulp in the second stirring tank 31 flows out into the container through the second through hole 3121. After all the jujube pulp has flowed out, the second cover plate 3122 is closed.

[0044] The apparatus for preparing jujube pulp according to this embodiment has the following technical advantages compared with the prior art: The process employs a first shearing and mixing mechanism, a connecting pipe, and a second shearing and mixing mechanism arranged in series, supported by a support frame, forming a continuous pulping process with primary coarsening and secondary refining. This eliminates the need for manual transfer of intermediate materials from the jujube orchard, ensuring smooth process flow, significantly reducing labor intensity, and minimizing material spillage and loss. The first and second shearing and mixing components within the first shearing and mixing mechanism form a vertical, bidirectional, three-dimensional shearing and mixing mode. The first component rotates horizontally while the second component rotates vertically, comprehensively dispersing and chopping the jujube raw material from different dimensions, eliminating excessive stirring. The shearing mechanism eliminates dead zones, ensuring more thorough and uniform crushing of raw materials, significantly improving the efficiency and particle size uniformity of coarse pulp preparation. The second shearing and mixing mechanism, driven by a second motor, rotates a crossbar via a drive shaft, causing two sets of third shearing and mixing components to revolve around the central axis of the drive shaft. Simultaneously, a waterproof motor drives the spiral blade to rotate, forming a combined revolution and rotation motion mode, performing secondary deep shearing, crushing, and homogenization of the coarse pulp. The symmetrically arranged two sets of third shearing and mixing components provide a large shearing coverage area. The spiral blade combines shearing and crushing with spiral propulsion and mixing, further breaking down fine particles in the coarse pulp while simultaneously mixing the pulp components, thus improving the quality of the final product.
