Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, specifically to a multi-component mixing equipment and method for flour based on particle homogenization. Background Technology

[0002] In the food processing industry, multi-component mixing of flour is a core process affecting the quality of end products. Whether it's baked goods like bread and biscuits, or flour-based products like noodles and steamed buns, the consistency of taste, nutritional balance, and shelf-life stability all highly depend on the homogenization effect of the flour components. For example, uneven distribution of dough improvers can lead to localized over- or under-fermentation in flour products, resulting in differences in texture. Fluctuations in the concentration of micronutrient fortifiers may not meet food nutritional standards and could even pose safety risks. Therefore, the industry's demand for multi-component particle homogenization of flour is becoming increasingly stringent, but existing flour mixing equipment is gradually failing to meet this core requirement, revealing numerous technical problems. In the existing technology, the mainstream flour mixing equipment is mainly divided into two categories. One is the fixed cavity type mixing equipment, whose core structure is a fixed mixing tank and an internal rotating mixing paddle. The other is the simple oscillating type mixing equipment. Both of these types of equipment rely on only a single motion and cannot achieve multi-dimensional dispersion of materials. At the same time, they cannot break up flour particle agglomeration and eliminate local accumulation. Furthermore, the screening, processing and mixing processes of the existing equipment are disconnected, which leads to the destruction of the homogenization effect when the multi-component flour is mixed by materials that do not meet the particle size requirements. Based on this, the present invention provides a flour multi-component mixing device and method based on particle homogenization to solve the problems mentioned in the background art. Summary of the Invention

[0003] This invention addresses the technical problems existing in the prior art by providing a flour multi-component mixing device and method based on particle homogenization.

Each of the two output shafts of the double-headed motor is equipped with a transmission shaft, both transmission shafts are rotatably connected to the device bracket, and each transmission shaft is connected to a first synchronous toothed belt. Swing shafts are mounted on both sides of the swing frame. One swing shaft is rotatably mounted on the device bracket and has a swing gear mounted on it. Two belt shafts are rotatably mounted on the device bracket, both belt shafts are connected to a first synchronous toothed belt, and both belt shafts have sector gears mounted on them. The two sector gears alternately mesh with the swing gear.

[0008] As a preferred technical solution of the present invention, the reciprocating swing mechanism further includes a hollow shaft rotatably sleeved on another swing shaft. The hollow shaft is rotatably connected to the equipment bracket through a bearing. The hollow shaft is driven by another first synchronous toothed belt. A second synchronous toothed belt is driven between the hollow shaft and the power shaft.

[0009] As a preferred technical solution of the present invention, the two sector gears are respectively disposed on both sides of the oscillating gear, and the effective meshing sections of the two sector gears are installed on the equipment support with a phase difference of 180°. In a single rotation cycle, the transmission angle of the sector gear to the oscillating gear is 45°.

[0010] As a preferred technical solution of the present invention, an input bevel gear is installed on the power shaft, and a first output bevel gear is installed on both the flip shaft and the gear shaft. Both first output bevel gears are connected to the input bevel gear in a transmission manner. The two first output bevel gears are symmetrically arranged with respect to the vertical plane where the axis of the power shaft is located. A second output bevel gear is installed on both the power shaft and the sleeve, and the two second output bevel gears are orthogonally meshed.

[0011] As a preferred technical solution of the present invention, a rotating bevel gear is installed on the sleeve, a passive bevel gear ring is installed on both the mixing chamber and the grinding cylinder, and both passive bevel gear rings are connected to the rotating bevel gear in a transmission manner. A linkage bevel gear is installed on both grinding chambers, and both passive bevel gear rings are meshed with the linkage bevel gear. An active bevel gear is installed on the gear shaft, and the active bevel gear is located inside the central cylinder. A first driven bevel gear that meshes with the active bevel gear is installed on both the grinding roller and the stirring shaft.

[0012] As a preferred technical solution of the present invention, the crushing mechanism includes a crushing shaft rotatably connected to the central cylinder, a second driven bevel gear meshing with the driving bevel gear is installed on the crushing shaft, the first driven bevel gear and the second driven bevel gear are both disposed on the inner side of the central cylinder, and crushing blades are arrayed on the inner wall of the crushing shaft and the crushing chamber, and the crushing shaft and the crushing blades on the crushing chamber are staggered.

[0013] As a preferred embodiment of the present invention, the axes of the mixing chamber, the tilting cylinder, the central cylinder, and the grinding cylinder are on the same straight line, the axis of the crushing chamber is perpendicular to the axis of the mixing chamber, and the axis of the swing shaft is perpendicular to the axis of the tilting cylinder.

[0014] A mixing method based on a multi-component flour mixing device for particle homogenization includes the following steps: S1. Material pre-dispersion: The feed rate, oscillation frequency and processing time parameters are set by the microcontroller. The flour components are fed into the turning drum through the feed pipe. The double-head motor drives the reciprocating oscillation mechanism. The swing frame oscillates back and forth on the equipment support at ±45°. At the same time, the turning frame drives the turning drum to turn, so that the material is turned over in both the axial and radial directions. S2. Grading and screening: After the material in the turning drum is swung and turned, the material along the axis direction enters the grinding drum and is ground through the grinding gap between the grinding roller and the grinding drum. The material along the vertical axis direction enters the two crushing chambers and is crushed by the staggered shearing of the crushing blades. The crushed and ground material returns to the turning drum and is screened by the filter screen. The material that meets the particle size requirements enters the mixing chamber, and the material that does not meet the requirements continues to be circulated for crushing or grinding. S3. Dynamic mixing and homogenization: The mixing chamber revolves under the drive of the rotary sleeve, while the stirring shaft rotates under the drive of the gear shaft. The stirring blades perform multi-dimensional mixing of the screened material until the homogenization requirements are met. After processing, the discharge control valve is opened, and the material is discharged under the action of gravity and oscillation inertia.

[0015] The beneficial effects of this invention are: 1. This invention solves the problem of existing mixing equipment having a single motion form and being unable to break up flour particle agglomeration and eliminate local accumulation by constructing a multi-dimensional composite motion and power linkage transmission system. On the one hand, a dual-head motor is used as the power source to drive the swing frame to achieve precise reciprocating swing of ±45°, while driving the turning drum to rotate around its own axis, so that the material forms a double turning in the radial and axial directions, breaking the static accumulation. On the other hand, the power shaft drives the rotating sleeve to rotate and the gear shaft to rotate synchronously through bevel gear transmission, forming a composite processing motion of the cavity cylinder revolution and the internal component rotation. The revolution motion expands the material movement range, and the rotation provides precise shear force and grinding force. The linkage of the two makes the material particles receive uniform force, avoiding local under-processing or over-processing.

[0016] 2. This invention integrates the crushing, grinding, sieving, and mixing processes in flour processing through a built-in dynamic screening and circulating processing link design. The filter screen is built into the connection between the tilting drum and the mixing chamber and moves synchronously with the tilting drum. It forms a closed loop with the grinding drum and the crushing chamber. After the material is swung and flipped, it automatically enters the grinding drum along the axis and the crushing chamber along the vertical axis. After processing, it returns to the tilting drum. The filter screen can screen the material in real time. Material that meets the particle size requirements directly enters the mixing chamber, while material that does not meet the requirements re-enters the grinding drum and the crushing chamber for circulating processing with the tilting drum. No manual intervention is required. This linkage and coordination of processing, screening, and reflux not only avoids the secondary agglomeration problem of existing external screening, but also ensures that the particle size of the material entering the mixing chamber is highly consistent. At the same time, it realizes the continuous operation of multiple processes and improves processing efficiency. Attached Figure Description

[0019] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0020] The present invention provides the following preferred embodiments. like Figure 1-10 As shown, a multi-component flour mixing device based on particle homogenization includes a device support 1, on which a reciprocating swing mechanism is installed. The mechanism is connected to a rotating power shaft 2 and a swing frame 3 that can reciprocate on the device support 1 at ±45°. The power shaft 2 is rotatably mounted on the swing frame 3. The reciprocating swing mechanism includes a double-headed motor 20 mounted on the equipment bracket 1. Both output shafts of the double-headed motor 20 are equipped with drive shafts 21, which are rotatably connected to the equipment bracket 1. A first synchronous toothed belt is connected to each of the two drive shafts 21. Swing shafts 22 are mounted on both sides of the swing frame 3. One swing shaft 22 is rotatably mounted on the equipment bracket 1 and is equipped with a swing gear 23. Two belt shafts 24 are rotatably mounted on the equipment bracket 1. Both belt shafts 24 are connected to a first synchronous toothed belt. Sector gears 25 are mounted on both belt shafts 24. The two sector gears 25 alternately mesh with the swing gear 23. Two sector gears 25 are respectively disposed on both sides of the oscillating gear 23. The effective meshing sections of the two sector gears 25 are installed on the equipment support 1 with a phase difference of 180°. In a single rotation cycle, the transmission angle of the sector gear 25 to the oscillating gear 23 is 45°. After the dual-head motor 20 starts, it drives the two transmission shafts 21 to rotate synchronously. The transmission shafts 21 drive the two belt shafts 24 to rotate through the first synchronous toothed belt. Since the two sector gears 25 are respectively installed on the belt shafts 24 and the effective meshing section has a phase difference of 180°, they will alternately mesh with the swing gear 23 on the swing shaft 22. When one side sector gear 25 meshes with the swing gear 23, it drives the swing shaft 22 to rotate forward by 45°. When the other side sector gear 25 meshes, it drives the swing shaft 22 to rotate backward by 45°, thus achieving a smooth reciprocating swing of the swing frame 3 along the equipment support 1 ±45°. This alternating meshing structure avoids the impact transmission of traditional swing mechanisms, making the swing frame 3 swing smoothly. At the same time, the ±45° swing angle can accurately drive the flour components inside the turning drum 6 to turn up and down, breaking the particle agglomeration phenomenon and providing a uniformly dispersed material basis for subsequent crushing and grinding processes. It effectively solves the problem of uneven mixing caused by local accumulation of materials in fixed mixing equipment and improves the uniformity of material pretreatment stage. The reciprocating swing mechanism also includes a hollow shaft 26 rotatably sleeved on another swing shaft 22. The hollow shaft 26 is rotatably connected to the equipment bracket 1 through a bearing. The hollow shaft 26 is driven by another first synchronous toothed belt. The hollow shaft 26 is driven by a second synchronous toothed belt connected to the power shaft 2. One of the drive shafts 21 of the dual-head motor 20 drives the hollow shaft 26 to rotate via the first synchronous toothed belt. The hollow shaft 26 then transmits power to the power shaft 2 via the second synchronous toothed belt, thereby enabling the power shaft 2 to rotate. At the same time, when the pendulum shaft 22 swings with the pendulum frame 3, the hollow shaft 26 can rotate independently in the bearing without interfering with the swinging action of the pendulum frame 3; The above-mentioned structural configuration distributes the power of the dual-head motor 20 to the reciprocating swing of the swing frame 3 and the rotation of the power shaft 2 simultaneously, eliminating the need for an additional drive motor, simplifying the overall structure of the equipment and reducing energy consumption. The bottom of the swing frame 3 is connected to the discharge control valve 4, and a tilting frame 5 is rotatably mounted on the swing frame 3. A tilting cylinder 6 is provided at the axis position of the tilting frame 5. The axis of the swing shaft 22 is perpendicular to the axis of the tilting cylinder 6; A microcontroller 18 is installed on the swing frame 3, and a feed pipe 19 is installed on the swing frame 3. The discharge port of the feed pipe 19 is connected to the rotating drum 6. The operator sets the feed rate, oscillation frequency and processing time parameters through the microcontroller 18, and the flour components enter the turning drum 6 through the feed pipe 19; The tipping cylinder 6 swings with the swing frame 3 ±45°, while the tipping frame 5 drives the tipping cylinder 6 to slowly turn over, and the material is double-turned in the radial and axial directions inside the tipping cylinder 6; After processing, open the discharge control valve 4 at the bottom of the swing frame 3, and the material will be completely discharged under the action of gravity and swing inertia; The addition of microcontroller 18 enables automated control of the equipment and reduces human error. The design of the swing shaft 22 being perpendicular to the axis of the tilting cylinder 6 makes the material tilting direction complementary to the radial processing direction of subsequent crushing and grinding, allowing the material to contact the crushing chamber 13 and the grinding cylinder 11 more evenly, eliminating processing dead angles in the tilting cylinder 6. A flipping shaft 7 is fixedly installed on the flipping cylinder 6, and a rotating sleeve 8 is rotatably sleeved on the flipping shaft 7. The rotating sleeve 8 is rotatably connected to the swing frame 3 through a rolling bearing. A central cylinder 9 is fixedly installed on the inner side of the flipping cylinder 6, and a gear shaft 10 coaxially arranged with the flipping shaft 7 is rotatably installed on the central cylinder 9. The gear shaft 10, the flipping shaft 7 and the rotating sleeve 8 are all driven by the power shaft 2. An input bevel gear is mounted on the power shaft 2, and first output bevel gears are mounted on both the flip shaft 7 and the gear shaft 10. Both first output bevel gears are connected to the input bevel gears. The two first output bevel gears are symmetrically arranged about the vertical plane where the axis of the power shaft 2 is located. Second output bevel gears are mounted on both the power shaft 2 and the sleeve 8. The two second output bevel gears are orthogonally meshed. When the power shaft 2 rotates, it drives the input bevel gear on it to rotate synchronously. The input bevel gear meshes with the two first output bevel gears on the flip shaft 7 and the gear shaft 10 at the same time, driving the flip shaft 7 and the gear shaft 10 to achieve coaxial and opposite rotation. At the same time, the second output bevel gear on the power shaft 2 meshes orthogonally with the second output bevel gear on the sleeve 8, changing the direction of power transmission and causing the sleeve 8 to rotate around its own axis. With the above structural setup, the power shaft 2 can simultaneously drive the three components of the tilting drum 6, the gear shaft 10, and the rotating sleeve 8 to move, thereby achieving multi-action coordination of the tilting drum 6 tilting and dispersing materials, the gear shaft 10 driving the processing components, and the rotating sleeve 8 driving the cavity to rotate. The tilting cylinder 6 is rotatably connected to the grinding cylinder 11, the mixing chamber 12, and two symmetrically arranged crushing chambers 13. The discharge end of the mixing chamber 12 is rotatably connected to the tilting frame 5. The other ends of the two crushing chambers 13 and the grinding cylinder 11 are rotatably connected to the tilting frame 5 through bearings. The axes of the mixing chamber 12, the tilting chamber 6, the central chamber 9, and the grinding chamber 11 are on the same straight line, and the axis of the crushing chamber 13 is perpendicular to the axis of the mixing chamber 12. A filter screen 14 is installed at the connection between the mixing chamber 12 and the tilting cylinder 6; The filter screen 14 is evenly distributed with filter holes. The axis of the filter holes is parallel to the axis of the flip cylinder 6. The diameter of the filter holes is customized according to the processing requirements of the flour components. The crushing chamber 13 is equipped with a crushing mechanism. The central cylinder 9 is rotatably connected to the grinding roller 15 and the stirring shaft 16. The filter screen 14 is rotatably connected to the stirring shaft 16 through the bearing. The grinding roller 15, the stirring shaft 16, the grinding cylinder 11, the mixing chamber 12 and the crushing chamber 13 are all driven by the gear shaft 10. There is a grinding gap between the grinding roller 15 and the grinding cylinder 11. The stirring shaft 16 is equipped with an array of stirring blades 17.

[0021] Under the action of swinging and turning, the material in the tipping drum 6 enters the grinding drum 11 along the axial direction and enters the two crushing chambers 13 along the perpendicular axial direction; The filter screen 14 at the connection between the crushing chamber 13 and the turning drum 6 will screen the material. The material that meets the particle size requirements will enter the mixing chamber 12 for mixing and stirring. The material that does not meet the requirements will remain in the turning drum 6 to continue turning and will enter the crushing drum and the grinding drum 11 for repeated processing until all the material particles are qualified. The qualified particle size material after grinding and crushing is finally fed into the mixing chamber 12 for homogenization and mixing. The layout of the mixing chamber 12, the tilting chamber 6, the central chamber 9, and the grinding chamber 11 having their axes collinear, and the crushing chamber 13 having its axis perpendicular to them, enables continuous multi-stage processing of crushing, grinding, and mixing, eliminating the need for manual material transfer and improving processing efficiency. The customized aperture design of the filter screen 14 can be adapted to different flour components, while ensuring the uniformity of the particle size of the material entering the mixing chamber 12. The grinding cylinder 11, the crushing chamber 13 and the tilting frame 5 are rotatably connected and move synchronously with the swing frame 3, which enhances the relative movement intensity of the material in the chamber and makes the processing more thorough. A rotating bevel gear 34 is installed on the sleeve 8. A passive bevel gear ring 27 is installed on both the mixing chamber 12 and the grinding cylinder 11. Both passive bevel gear rings 27 are connected to the rotating bevel gear 34 for transmission. Both crushing chambers 13 are installed with linkage bevel gears 28. Both passive bevel gear rings 27 are meshed with the linkage bevel gears 28. A drive bevel gear 31 is mounted on the gear shaft 10. The drive bevel gear 31 is located inside the central cylinder 9. Both the grinding roller 15 and the stirring shaft 16 are equipped with a first driven bevel gear 32 that meshes with the drive bevel gear 31.

[0022] The crushing mechanism includes a crushing shaft 29 rotatably connected to the central cylinder 9. A second driven bevel gear 33 that meshes with the driving bevel gear 31 is mounted on the crushing shaft 29. The first driven bevel gear 32 and the second driven bevel gear 33 are both located inside the central cylinder 9. Crushing blades 30 are arrayed on the inner walls of both the crushing shaft 29 and the crushing chamber 13. The crushing shaft 29 and the crushing blades 30 on the crushing chamber 13 are staggered. The rotating sleeve 8 drives the rotating bevel gear 34 to mesh with the passive bevel gear ring 27 on the mixing chamber 12 and the grinding chamber 11, driving the two chambers to rotate synchronously. At the same time, the passive bevel gear ring 27 drives the crushing chamber 13 to rotate through the linkage bevel gear 28. The driving bevel gear 31 on the gear shaft 10 meshes with the first driven bevel gear 32 and the second driven bevel gear 33 respectively. The grinding roller 15 grinds the material through the grinding gap. The paddle on the stirring shaft 16 stirs the material in the mixing chamber 12. The crushing blade 30 on the crushing shaft 29 rotates in a staggered manner with the crushing blade 30 on the inner wall of the crushing chamber 13 to shear and crush the material. Through the transmission of the rotating bevel gear 34, the passive bevel gear ring 27, and the linkage bevel gear 28, the synchronous rotation of the mixing chamber 12, the grinding chamber 11, and the crushing chamber 13 is achieved. Combined with the rotation of the internal components, a compound motion of the chamber revolution and the component rotation is formed, so that the shearing and grinding forces on the material are more uniform, avoiding local over-processing or under-processing, and improving the particle homogenization of flour components. The 30-degree offset setting of the crushing blades increases the crushing contact area, reduces material slippage, and improves crushing efficiency; The active bevel gear 31 synchronously drives multiple processing components, ensuring that the speed of each process is matched, and ultimately achieving high-precision mixing of multi-component flour, meeting the stringent requirements of food processing for mixing uniformity.

[0023] A mixing method based on a multi-component flour mixing device for particle homogenization includes the following steps: S1. Material pre-dispersion: The feed rate, oscillation frequency and processing time parameters are set by the microcontroller 18. The flour components are input into the turning drum 6 through the feed pipe 19. The double-head motor 20 is started to drive the reciprocating oscillation mechanism. The swing frame 3 oscillates back and forth on the equipment support 1 at ±45°. At the same time, the turning frame 5 drives the turning drum 6 to turn, so that the material is turned over in both the axial and radial directions. S2. Grading and screening: After the material in the turning drum 6 is swung and turned, the material along the axis direction enters the grinding drum 11 and is ground through the grinding gap between the grinding roller 15 and the grinding drum 11. The material along the vertical axis direction enters the two crushing chambers 13 and is crushed by the staggered shearing of the crushing blades 30. The crushed and ground material returns to the turning drum 6 and is screened by the filter screen 14. The material that meets the particle size requirements enters the mixing chamber 12, and the material that does not meet the requirements continues to be circulated for crushing or grinding. S3. Dynamic mixing and homogenization: The mixing chamber 12 revolves under the drive of the rotating sleeve 8, while the stirring shaft 16 rotates under the drive of the gear shaft 10. The stirring blades 17 perform multi-dimensional stirring of the screened material until the homogenization requirements are met. After processing, the discharge control valve 4 is opened, and the material is discharged under the action of gravity and oscillation inertia.
