Description

A brown sugar homogenizing device Technical Field

[0001] This utility model relates to the field of brown sugar homogenization technology, and in particular to a brown sugar homogenization device. Background Technology

[0002] In the production of brown sugar, as a sucrose product containing water of crystallization, the uniformity of its granules directly affects the quality of subsequent processing. For example, in baking, uneven granules lead to inconsistent melting rates, affecting the texture of pastries; when used in beverage formulation, differences in granule size can cause incomplete dissolution and uneven color, thus impacting taste and appearance. Therefore, the ability of homogenizing equipment to achieve uniform sugar granule processing plays a decisive role in the dissolution rate, color stability, and taste consistency of brown sugar in downstream applications such as baking and beverages, and is a core element in ensuring product quality.

[0003] Currently, in the homogenization production process of brown sugar, a screening structure is usually required inside the equipment to screen the homogenized brown sugar to avoid excessive differences in particle size. However, the existing structure usually uses the free gravity of the falling material in conjunction with the inclined screen plate to achieve screening, which results in poor screening efficiency. Some equipment that uses a vibrating motor will generate a lot of noise pollution during use. Summary of the Invention

[0004] To address the shortcomings of conventional screening methods that rely on the free gravity of falling materials in conjunction with inclined sieve plates, which result in poor screening efficiency and generate significant noise pollution during operation when using equipment with vibrating motors, this invention provides a brown sugar homogenizing device that offers advantages such as high-efficiency screening and low noise, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a brown sugar homogenizing device, including a box body, a shearing cavity at the upper end of the box body, a processing cavity at the bottom of the box body, two homogenizing rollers installed inside the processing cavity, a sieve plate at the bottom of the homogenizing rollers, a fixing plate fixedly installed at each of the four corners of the inner wall of the processing cavity, a vibration spring fixedly installed at the upper end of each fixing plate, and the upper ends of multiple vibration springs fixedly installed at the bottom of the four corners of the sieve plate, a sprocket fixedly installed on one side of each of the two homogenizing rollers penetrating the box body, a second pulley fixedly installed on the outer side of one of the sprockets, a transmission belt drivingly connected to the surface of the second pulley, a first pulley drivingly connected to the inner bottom of the transmission belt, a drive rod fixedly installed on the inner side of the first pulley, a cam fixedly installed on the inner side of the drive rod penetrating the box body, and the cam being located at the lower middle part of the sieve plate.

[0006] Preferably, the cam lifts the screen plate once every time it rotates around its own axis, and a discharge hopper is fixedly installed on the side of the box, with the inner side of the discharge hopper located on the lower side of the screen plate.

[0007] By setting the cam to lift the screen plate once a week, the screen plate vibrates regularly, which, together with the discharge hopper, enables efficient screening and directional discharge of sugar.

[0008] Preferably, a rotating shaft is rotatably mounted inside the shearing chamber, and a rotary motor is mounted on the upper end of the housing. The output shaft of the rotary motor is connected to the upper end of the rotating shaft via a coupling.

[0009] A rotary motor drives the crushing blades to rotate at high speed, thereby pre-crushing the brown sugar to reduce the particle size.

[0010] Preferably, a plurality of crushing blades are fixedly mounted on the surface of the rotating shaft, and a plurality of material leakage holes are provided at the bottom of the shearing chamber, with the bottom of the material leakage holes extending to the upper end of the processing chamber.

[0011] Preferably, a servo motor is installed on the outer side of the middle part of the housing, and the output shaft of the servo motor is connected to one end of one of the homogenizing rollers through a coupling. A sprocket belt is meshed on the surface of the sprocket.

[0012] By connecting the homogenizing roller to the servo motor, the homogenizing roller is driven to rotate and linked to another roller via a sprocket, thus realizing the power output for extruding and homogenizing brown sugar.

[0013] Preferably, a gearbox is fixedly installed on the side of the housing near the sprocket, and the first pulley, the second pulley, and the sprocket are all housed inside the gearbox.

[0014] By integrating transmission components into the gearbox, a closed lubrication environment is formed, reducing noise, dust intrusion, and component wear, thus ensuring transmission stability.

[0015] This utility model has the following advantages:

[0016] 1. By setting up a cam-driven vibrating screening structure linked to the homogenizing roller, the four corners of the bottom of the screening plate are connected to the processing chamber through vibration springs. When the servo motor drives the homogenizing roller to rotate, the second pulley drives the first pulley to rotate through the transmission belt, causing the cam to rotate with the drive rod and periodically lift the screening plate. The screening plate generates regular vibration under the elastic reset action of the vibration spring. The screening mechanism is synchronously driven by the power of the homogenizing roller transmission chain. There is no need to set up an additional vibration motor. Flexible vibration screening is achieved through the cooperation of the cam and the vibration spring, which avoids the noise problem of rigid vibration and disperses sugar particles through the vibration of the screening plate, preventing adhesion and clogging of the screen holes, and improving screening efficiency.

[0017] 2. By setting a rotating shaft and crushing blades inside the shearing chamber, the output shaft of the rotary motor drives the rotating shaft to rotate through a coupling, causing the crushing blades to rotate at high speed inside the shearing chamber. This pre-crushes the brown sugar at the top of the feeding box, cutting large pieces of sugar into smaller particles that fall into the processing chamber through the discharge hole. This structure uses the shearing force of the blades to initially crush the sugar, reducing the load on the homogenizing rollers during extrusion. At the same time, it makes the sugar particles entering the processing chamber more uniform in size, reduces the impact load on the homogenizing rollers caused by processing large pieces of sugar, extends the service life of the equipment, and provides more stable material conditions for subsequent screening.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5. A brown sugar homogenizing device includes a housing 1. A shearing chamber 2 is provided at the upper end of the housing 1, and a processing chamber 7 is provided at the bottom of the housing 1. Two homogenizing rollers 9 are installed inside the processing chamber 7. The surface of the homogenizing rollers 9 is provided with crushing teeth. Both ends of the inner wall of the processing chamber 7 are provided with shearing teeth that fit with the crushing teeth. The two cooperate with each other to realize the crushing and homogenizing operation of brown sugar material. Since this structure belongs to the conventional technology known to those skilled in the art, it is not shown in the figure. When the homogenizing rollers 9 rotate, the crushing teeth on their surface and the shearing teeth on the cavity wall form a shearing area that moves in opposite directions, generating a combined squeezing and shearing effect on the brown sugar entering the processing chamber 7. A sieve plate 12 is provided at the bottom of the homogenizing rollers 9, which can screen the homogenized brown sugar particles by particle size, so that the fine particles that meet the requirements are discharged through the sieve holes, and the coarse particles are retained for secondary processing to ensure the uniformity of product particles.

[0026] Fixed plates 13 are fixedly installed at the four corners of the inner wall of the processing chamber 7. Vibration springs 14 are fixedly installed at the upper end of each fixed plate 13. The upper ends of multiple vibration springs 14 are respectively fixedly installed at the bottom of the four corners of the sieve plate 12. Vibration springs 14 are set at the four corners of the inner wall of the processing chamber 7 to connect the sieve plate 12. The elastic support of the springs makes the sieve plate 12 generate flexible vibration. The sieve plate 12 generates regular vibration under the elastic reset action of the vibration springs 14. The power of the homogenizing roller 9 transmission chain synchronously drives the screening mechanism. There is no need to set up an additional vibration motor. Flexible vibration screening is achieved through the cooperation of cam 17 and vibration spring 14. This avoids the noise problem of rigid vibration and disperses sugar particles through the vibration of the sieve plate 12, preventing adhesion and clogging of the sieve holes, and improving screening efficiency.

[0027] One side of each of the two homogenizing rollers 9 passes through the housing 1 and is fixedly equipped with a sprocket 10. A second pulley 20 is fixedly installed on the outer side of one of the sprockets 10. A transmission belt 21 is driven to the surface of the second pulley 20. A first pulley 19 is driven to the inner side of the bottom of the transmission belt 21. A drive rod 18 is fixedly installed on the inner side of the first pulley 19. A cam 17 is fixedly installed on the inner side of the drive rod 18, passing through the housing 1. The cam 17 is located at the lower middle part of the screen plate 12. A cam 17 vibration screening structure is set up to be linked with the homogenizing rollers 9. The four corners of the bottom of the screen plate 12 are connected to the processing chamber 7 through vibration springs 14. When the servo motor 8 drives the homogenizing rollers 9 to rotate, the second pulley 20 drives the first pulley 19 to rotate through the transmission belt 21, so that the cam 17 rotates with the drive rod 18 and periodically lifts the screen plate 12.

[0028] Please refer to Figures 2-5. The cam 17 lifts the screen plate 12 once every time it rotates around its own axis. The discharge hopper 15 is fixedly installed on the side of the housing 1, and the inner side of the discharge hopper 15 is located on the lower side of the screen plate 12.

[0029] A rotating shaft 3 is rotatably installed inside the shearing chamber 2. A rotary motor 5 is installed at the upper end of the housing 1. The output shaft of the rotary motor 5 is connected to the upper end of the rotating shaft 3 through a coupling. Multiple crushing blades 4 are fixedly installed on the surface of the rotating shaft 3. By setting the rotating shaft 3 and crushing blades 4 inside the shearing chamber 2, the output shaft of the rotary motor 5 drives the rotating shaft 3 to rotate through the coupling, causing the crushing blades 4 to rotate at high speed in the shearing chamber 2. This pre-crushes the brown sugar fed into the upper end of the housing 1, cutting large pieces of sugar into smaller particles, which then fall into the processing chamber 7 through the discharge hole 6. This structure uses the shearing force of the blades to initially crush the sugar, reducing the load on the homogenizing roller 9 during extrusion. At the same time, it makes the sugar particles entering the processing chamber 7 more uniform in size, reduces the impact load on the homogenizing roller 9 caused by processing large pieces of sugar, extends the service life of the equipment, and provides more stable material conditions for the subsequent screening process. Multiple discharge holes 6 are opened at the bottom of the shearing chamber 2, and the bottom of the discharge holes 6 extends to the upper end of the processing chamber 7.

[0030] A servo motor 8 is installed on the outer side of the middle part of the housing 1. The output shaft of the servo motor 8 is connected to one end of one of the homogenizing rollers 9 through a coupling. A sprocket belt 11 is meshed on the surface of the sprocket 10. A gearbox 16 is fixedly installed on the side of the housing 1 near the sprocket 10. The first pulley 19, the second pulley 20 and the sprocket 10 are all located in the gearbox 16. The transmission components are integrated through the gearbox 16 to form a closed lubrication space, which reduces dust intrusion and component wear, reduces noise and improves the stability of the transmission system, and ensures long-term reliable operation of the equipment.

[0031] Working principle: In actual use, the brown sugar to be homogenized is first put into the shearing chamber 2 at the top of the box 1, and the rotary motor 5 is started. Its output shaft drives the rotary shaft 3 and the crushing blade 4 to rotate at high speed through the coupling, so that the brown sugar is pre-crushed and large pieces of sugar are cut into smaller particles. Then, the sugar falls into the processing chamber 7 below through the leakage hole 6 at the bottom of the shearing chamber 2.

[0032] Inside the processing chamber 7, the servo motor 8 is started to drive one of the homogenizing rollers 9 to rotate. This homogenizing roller 9 drives the other homogenizing roller 9 to rotate synchronously through the meshing transmission of the sprocket 10 and sprocket belt 11. It works in conjunction with the shearing teeth installed on the inner wall of the processing chamber to shear and crush the material. At the same time, the transmission system linked with the homogenizing roller 9 starts to work: the second pulley 20 fixed on the outside of the sprocket 10 on one side of the homogenizing roller 9 drives the first pulley 19 and the drive rod 18 to rotate through the transmission belt 21. This causes the cam 17 connected to the end of the drive rod 18 to rotate around its own axis. Every time the cam 17 rotates once, its protruding part pushes the screen plate 12 upward once. Under the elastic support of the vibration springs 14 on the four corner fixing plates 13 of the inner wall of the processing chamber 7, the screen plate 12 produces regular up and down vibration.

[0033] During the vibration process, the homogenized brown sugar particles are screened on the screen plate 12. Fine sugar particles that meet the particle size requirements fall through the screen holes and enter the subsequent processing steps. Coarse sugar particles that do not pass through the screen holes move towards the discharge hopper 15 as the screen plate 12 vibrates and are eventually discharged from the discharge hopper 15 on the side of the box 1. They can be collected manually and reprocessed.

[0034] The No. 1 pulley 19, No. 2 pulley 20 and sprocket 10 in the transmission system are all integrated into the gearbox 16. The enclosed structure not only reduces the risk of exposed transmission components, but also reduces noise and prevents sugar dust from entering through internal lubrication, ensuring stable operation of the equipment and food hygiene standards.
