Description

Technical Field

[0001] This utility model relates to the field of dairy product testing technology, and in particular to a fermented milk fruit particle screening device. Background Technology

[0002] Fermented milk is made from fresh milk through lactic acid bacteria fermentation. It is nutritionally complete and popular with consumers. During the production of fermented milk beverages, a certain amount of fruit pieces is usually added to enhance the taste and flavor. To ensure that the fruit piece content meets standards, sampling and testing of the fruit piece content in the beverages is necessary.

[0003] Currently, traditional sampling and testing methods involve manual screening. Fermented dairy beverages are poured directly onto a sieve to separate fruit particles from the fermented milk, and then the number of fruit particles remaining on the sieve is manually counted. This method suffers from low testing efficiency and wastes manpower. Existing fruit particle sieving instruments involve pouring beverages through pipes into the instrument, simultaneously sieving and washing the fruit particles. However, beverages containing fruit particles can easily clog the pipes. Furthermore, the sieved fruit particles remain stationary within the instrument, resulting in poor cleaning. When multiple types of fruit particles with similar colors are present, this can lead to significant errors in subsequent testing results. Utility Model Content

[0064] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0065] This embodiment provides a fermented milk fruit particle screening device for screening fruit particles in beverages, separating the fruit particles from the fermented milk, so as to facilitate sampling and testing of the fruit particle content in the beverage.

[0066] like Figures 1 to 6 As shown, the fermented milk fruit particle screening device includes a tank 1, a screening structure 2, a feeding structure 3, and a cleaning structure 4. The tank 1 is surrounded by a fixed chamber 10, within which a fixed plate 11 is installed. The screening structure 2 includes a screening barrel 21, a vibration mechanism (not shown), and a screen 22. The screening barrel 21 is rotatably mounted on the fixed plate 11. The vibration mechanism is located inside the screening barrel 21, and the screen 22 is located inside the screening barrel 21 and connected to the output end of the vibration mechanism. The feeding structure 3 includes a feeding pipe 31 connected to the screening barrel 21 to deliver the beverage to be sampled into the screening barrel 21. The cleaning structure 4 includes a first water supply pipe 41 and multiple nozzles 42. The first water supply pipe 41 is located inside the fixed chamber 10 and spaced above the screening barrel 21. The multiple nozzles 42 are spaced along the extension direction of the first water supply pipe 41 to thoroughly rinse the fruit particles screened on the screen 22. The screen 22 vibrates under the drive of the vibration mechanism to prevent fruit particles from accumulating, ensuring smooth screening while also ensuring that the spray nozzle 42 thoroughly washes the fruit particles. Multiple through holes are spaced apart on the fixed plate 11 for the separated fermented milk to flow out.

[0067] Two electromagnets 111 are spaced apart on the fixed plate 11. Each electromagnet 111 has a magnetic state and a non-magnetic state. A first magnetic element 221 is provided on the bottom side of the screen 22. During the rotation of the screening barrel 21, when the first magnetic element 221 aligns with the electromagnet 111, and the electromagnet 111 is in a magnetic state, the first magnetic element 221 and the electromagnet 111 attract each other, causing the screen 22 to rotate. Figure 2 The tilted shape, as shown, causes the fruit particles on the screen 22 to roll, further improving the cleaning effect. When the electromagnet 111 is in a non-magnetic state, the screen 22 is horizontal. That is to say, during the rotation of the screening barrel 21, when the first magnetic component 221 aligns and attracts the electromagnet 111 on the left, it will cause the screen 22 to tilt to the left; and when the screening barrel 21 rotates until the first magnetic component 221 aligns and attracts the electromagnet 111 on the right, it will cause the screen 22 to tilt to the right, thereby causing the fruit particles to roll left and right, improving the cleaning effect and ensuring the accuracy of subsequent test results.

[0068] It should be noted that, as Figure 3 As shown, the first magnetic element 221 is located on one side of the center of the screen 22, and any electromagnet 111 is attracted to the first magnetic element 221 when it is in a magnetic state.

[0069] Specifically, in this embodiment, the fixed end of the vibration mechanism is disposed on the inner wall of the screening barrel 21, and the output end is connected to the screen 22 to extend the service life of the vibration mechanism; alternatively, in other embodiments, the fixed end of the vibration mechanism can also be disposed on the screen 22, that is, during the vibration of the screen 22, the fixed end of the vibration mechanism also vibrates. The specific location of the vibration mechanism is not specifically limited, as long as it can drive the screen 22 to vibrate. Exemplarily, the vibration mechanism is a vibration motor commonly used in the art, and its specific structure and principle refer to the prior art, which will not be described in detail here.

[0070] For example, in this embodiment, five nozzles 42 are spaced apart; in other embodiments, the number of nozzles 42 can be set as needed, and no specific limitation is made here.

[0071] Specifically, the electromagnet 111 also has an existing structure; it is magnetic when energized and non-magnetic when de-energized. The first magnetic component 221 is a magnet commonly used in this field.

[0072] Optionally, such as Figure 4 As shown, a discharge port 212 is provided on one side of the screening barrel 21, and a baffle 213 is provided at the discharge port 212. The discharge port 212 has a blocked state and an open state. In the blocked state, the baffle 213 blocks the discharge port 212. In the open state, the baffle 213 is separated from the discharge port 212 to facilitate the removal of fruit particles.

[0073] Furthermore, a telescopic mechanism 214 is provided on the side wall of the screening barrel 21. A stop block 213 is connected to the output end of the telescopic mechanism 214. Driven by the telescopic mechanism 214, the stop block 213 can switch between blocking the discharge port 212 and separating from the discharge port 212. Specifically, in this embodiment, a receiving cavity is opened on the side wall of the screening barrel 21, and the discharge port 212 is connected to the receiving cavity. The stop block 213 and the telescopic mechanism 214 are both disposed in the receiving cavity. In other embodiments, the telescopic mechanism 214 and the stop block 213 can also be disposed on the outer wall of the screening barrel 21. Exemplarily, the telescopic mechanism 214 is a cylinder commonly used in the art.

[0074] Furthermore, continue to refer to Figure 4 The outer wall of the screening barrel 21 is provided with an inclined tube 215, which is connected to the discharge port 212. When it is necessary to remove the screened fruit pieces, the screening barrel 21 is rotated so that the first magnetic component 221 is aligned with the electromagnet 111 on the side near the discharge port 212, and the electromagnet 111 is adjusted to a magnetic state. Under the magnetic force of the first magnetic component 221 and the electromagnet 111, the screen 22 is tilted, which drives the fruit pieces to enter the inclined tube 215 along the inclined screen 22 under their own gravity, and then separates them from the screening barrel 21.

[0075] Specifically, in this embodiment, combined with Figure 1 and Figure 2 The tank body 1 is equipped with an inclined plate 15, and a feeding port 16 is provided on the side wall of the tank body 1. The fruit particles flowing out through the inclined tube 215 fall onto the inclined plate 15. Since the inclined plate 15 is inclined, the fruit particles falling onto the inclined plate 15 can automatically flow out of the tank body 1 from the feeding port 16. In other embodiments, a collection box can also be provided at the end of the inclined tube 215 away from the screening barrel 21, and the collection box can be directly taken out through the feeding port 16.

[0076] More specifically, such as Figure 1 As shown, a drain pipe 17 is also provided at the bottom of the tank 1. The drain pipe 17 is used to promptly discharge the separated fermented milk and the water used to wash the fruit particles from the fixed chamber 10. Exemplarily, in this embodiment, the bottom of the tank 1 is arc-shaped, and the drain pipe 17 is located at the lowest point of the bottom of the tank 1. In addition, multiple support legs are provided circumferentially on the outer side of the tank 1 to ensure the stability of the tank 1.

[0077] Optionally, such as Figure 3 As shown, a second magnetic element 222 is slidably disposed on the bottom side of the screen 22, combined with... Figure 2When the screen 22 is tilted, the electromagnet 111, which is attracted to the first magnetic element 221, is also attracted to the second magnetic element 222. This arrangement increases the magnetic attraction force on the screen 22, thereby increasing the tilt angle of the screen 22. This enhances the rolling of the fruit particles and improves the washing effect, while also ensuring that the screened fruit particles can be smoothly discharged from the outlet 212. Specifically, the second magnetic element 222 is a magnet commonly used in this field.

[0078] Optionally, the screening structure 2 further includes two connecting components 23, which are respectively disposed on opposite sides of the screen 22; for example Figure 4 As shown, the connecting assembly 23 includes a mounting plate 231 and an elastic element 232. The mounting plate 231 is disposed on the inner wall of the screening barrel 21 and spaced apart on the bottom side of the screen 22. The elastic element 232 extends vertically and connects the screen 22 and the mounting plate 231. When the screen 22 tilts to one side, the elastic element 232 on that side is compressed and deformed, accumulating elastic potential energy. When the magnetic force between the first magnetic element 221 and the electromagnet 111 disappears or weakens, the screen 22 returns to a horizontal state under the elastic action of the elastic element 232. Exemplarily, in this embodiment, the elastic element 232 is a spring, which is readily available and has good economic performance.

[0079] Optionally, such as Figure 1 and Figure 2 As shown, the feeding structure 3 also includes a tilting hopper 32 and a discharge pipe 33. The tilting hopper 32 is connected to the first end of the feeding pipe 31, and the discharge pipe 33 is connected to the second end of the feeding pipe 31. The feeding pipe 31 is rotatably mounted on the tank 1 in a vertical direction, and the extension direction of the discharge pipe 33 is at an angle to the vertical direction. With the above configuration, the beverage to be tested is poured into the tilting hopper 32 and fed into the discharge pipe 33 through the feeding pipe 31. As the feeding pipe 31 rotates, the discharge pipe 33 can evenly feed the beverage onto the screen 22 circumferentially, effectively preventing beverage accumulation and facilitating the screening of fruit particles.

[0080] Specifically, the pouring hopper 32 is funnel-shaped, which facilitates the pouring of beverages and also allows the beverages to smoothly enter the feed pipe 31 along the inner wall of the pouring hopper 32.

[0081] Specifically, a rotating mechanism can be provided on the tank body 1 to drive the rotation of the feed pipe 31. For example, the rotating mechanism is a rotary motor commonly used in the art.

[0082] Furthermore, such as Figure 1 As shown, the cleaning structure 4 also includes a second water supply pipe 43, the outlet of which is connected to the tilting bucket 32 ​​to rinse the beverage adhering to the inner wall of the tilting bucket 32, ensuring that the fruit pieces and fermented milk can fall into the screening bucket 21, while avoiding blockage of the feed pipe 31 and the discharge pipe 33.

[0083] Optionally, in this embodiment, refer to Figure 1 The cleaning structure 4 also includes a water tank 44, which houses a water pump. The inlet ends of the first water pipe 41 and the second water pipe 43 are both connected to the output end of the water pump to provide sufficient water for rinsing the fruit pieces. Specifically, in this embodiment, the water tank 44 is located on the outer wall of the tank body 1; in other embodiments, the water tank 44 may be designed separately from the tank body 1. The water pump is a prior art device and will not be described in detail here.

[0084] Furthermore, continue to refer to Figure 1 The cleaning structure 4 also includes a water supply pipe 45 and a regulating valve 46. The inlet end of the water supply pipe 45 is connected to the water tank 44. The inlets of the first water supply pipe 41 and the second water supply pipe 43 are both connected to the outlet end of the water supply pipe 45, and the regulating valve 46 is located at the outlet end of the water supply pipe 45. The regulating valve 46 can change the direction of water flow at the outlet end of the water supply pipe 45. The water flow at the outlet end of the water supply pipe 45 can flow simultaneously to both the first water supply pipe 41 and the second water supply pipe 43, or it can flow only to the first water supply pipe 41 or only to the second water supply pipe 43. Specifically, the regulating valve 46 is a prior art device, and its specific structure and principle are based on existing technology and will not be described in detail here.

[0085] Optionally, refer to Figure 3 A support rod 211 is provided on the bottom side of the screening barrel 21, and the support rod 211 is rotatably mounted on the fixed plate 11. This fermented milk granule screening device also includes a drive structure 5, combined with... Figure 1 The drive structure 5 includes a drive mechanism 51, a first rotating rod 52, and a first transmission assembly 53. The drive mechanism 51 is disposed on the tank body 1, and the first rotating rod 52 is rotatably disposed on the inner wall of the fixed chamber 10 and connected to the output end of the drive mechanism 51. The first transmission assembly 53 includes a first bevel gear 531 and a second bevel gear 532. The first bevel gear 531 is disposed at the end of the first rotating rod 52, and the second bevel gear 532 is sleeved on the support rod 211 and meshes with the first bevel gear 531. Driven by the drive mechanism 51, the first rotating rod 52 rotates around its own axis, simultaneously driving the first bevel gear 531 to rotate, which in turn drives the second bevel gear 532 to rotate, thereby driving the support rod 211 and the screening tank 21 to rotate.

[0086] Specifically, in this embodiment, the drive mechanism 51 is disposed on the outer wall of the tank 1; in other embodiments, the drive mechanism 51 may also be disposed on the inner wall of the tank 1. Exemplarily, the drive mechanism 51 is a motor commonly used in the art.

[0087] Furthermore, the first transmission assembly 53 also includes a one-way bearing (not shown in the figure), which is disposed between the first rotating rod 52 and the first bevel gear 531. When the first rotating rod 52 rotates in the first direction, it drives the first bevel gear 531 to rotate; while when the first rotating rod 52 rotates in the second direction, the first bevel gear 531 does not rotate, and the first direction is opposite to the second direction. The above arrangement ensures that the screening barrel 21 can only rotate in one direction, so that the screened fruit particles form a stable motion trajectory on the screen 22, effectively avoiding sudden changes in the trajectory of the fruit particles or clogging of the screen 22 due to sudden changes in the direction of rotation. Specifically, the one-way bearing is an existing structure in the art and will not be described in detail here.

[0088] Optionally, such as Figure 1 As shown, a first transmission rod 12 is rotatably mounted on the inner wall of the fixed chamber 10, and the first transmission rod 12 is spaced between the first water supply pipe 41 and the first rotating rod 52. The first water supply pipe 41 is rotatably mounted inside the fixed chamber 10, and a torsion spring 411 is provided between one end of the first water supply pipe 41 and the inner wall of the fixed chamber 10. The drive structure 5 also includes a second transmission assembly 54 and a third transmission assembly 55. One end of the second transmission assembly 54 is sleeved on the first transmission rod 12, and the other end is sleeved on the first rotating rod 52. (Refer to...) Figure 5 The third transmission assembly 55 includes an incomplete gear 551 and a driven gear 552. The incomplete gear 551 is sleeved on the first transmission rod 12, and the driven gear 552 is sleeved on the first water supply pipe 41. The third transmission assembly 55 has a transmission state and a non-transmission state. In the transmission state, the incomplete gear 551 meshes with the driven gear 552 to drive the first water supply pipe 41 and the torsion spring 411 to rotate in the forward direction; in the non-transmission state, the incomplete gear 551 is not meshed with the driven gear 552, and the first water supply pipe 41 rotates in the reverse direction under the elastic action of the torsion spring 411.

[0089] With the above configuration, when the drive mechanism 51 drives the first rotating rod 52 to rotate, the second transmission component 54 can simultaneously drive the first transmission rod 12 and the incomplete gear 551 to rotate. The incomplete gear 551 includes a toothed part and a toothless part. When the driven gear 552 meshes with the toothed part of the incomplete gear 551, it can drive the rotation of the first water pipe 41 and the torsion spring 411, expanding the spray range of the nozzle 42 while the torsion spring 411 accumulates elastic potential energy. When the incomplete gear 551 rotates until its toothless part contacts the driven gear 552, that is, when the incomplete gear 551 and the driven gear 552 disengage, the torsion spring 411 releases its elastic potential energy, driving the first water pipe 41 to move in the opposite direction. By continuously switching the third transmission component 55 between the transmission state and the non-transmission state, the spray range of the nozzle 42 can be expanded, further improving the rinsing effect on the fruit particles, while also preventing fermented milk from adhering to the screen 22.

[0090] Specifically, in this embodiment, the first water supply pipe 41 is provided with a torsion spring 411 at only one end, and the other end is rotatably mounted on the tank body 1 through a rotary joint 412. The rotary joint 412 is an existing structure and will not be described in detail here. In other embodiments, the first water supply pipe 41 may also be provided with torsion springs 411 at both ends.

[0091] Specifically, the second transmission component 54 is a transmission chain or transmission belt commonly used in the art, and its specific structure and principle are based on existing technology and will not be described in detail here; the torsion spring 411 is also an existing structure and will not be described in detail here. In addition, the ratio of toothed to gearless parts of the incomplete gear 551 can be set as needed and is not specifically limited here.

[0092] Furthermore, such as Figure 1 and Figure 6 As shown, a second transmission rod 13 is rotatably mounted on the inner wall of the fixed chamber 10. The drive structure 5 also includes a fourth transmission assembly 56 and a fifth transmission assembly 57. One end of the fourth transmission assembly 56 is sleeved on the first water supply pipe 41, and the other end is sleeved on the second transmission rod 13. The fifth transmission assembly 57 includes a third bevel gear 571 and a fourth bevel gear 572. The third bevel gear 571 is sleeved on the second transmission rod 13, and the fourth bevel gear 572 is sleeved on the feed pipe 31 and meshes with the third bevel gear 571. With the above configuration, when the first water supply pipe 41 rotates, the fourth transmission assembly 56 can synchronously drive the second transmission rod 13 and the third bevel gear 571 to rotate, thereby driving the fourth bevel gear 572 and the feed pipe 31 to rotate, so that the beverage is evenly distributed on the screen 22. There is no need to add an additional power source to drive the rotation of the feed pipe 31, reducing the manufacturing cost of the device and realizing the lightweight design of the device.

[0093] Specifically, a fixing block 14 is provided on the inner wall of the fixed chamber 10, and the second transmission rod 13 is rotatably inserted through the fixing block 14. The fourth transmission component 56 is also a transmission chain or transmission belt commonly used in the art, and its specific structure and principle are as described in the prior art, and will not be repeated here.

[0094] For example, the operation process of the fermented milk fruit particle screening device provided in this embodiment is as follows:

[0095] The drive mechanism 51 is activated, causing the first rotating rod 52 to rotate in the second direction. The first bevel gear 531, support rod 211, and screening barrel 21 do not rotate. However, the second transmission rod 13 rotates synchronously with the first rotating rod 52 under the transmission action of the second transmission assembly 54. When the third transmission assembly 55 is in the transmission state, the first water supply pipe 41 rotates in the forward direction; when the third transmission assembly 55 is not in the transmission state, the first water supply pipe 41 rotates in the reverse direction under the action of the torsion spring 411. When the first water supply pipe 41 rotates, under the transmission action of the fourth transmission assembly 56 and the fifth transmission assembly 57, it can drive the feed pipe 31 to rotate, and at the same time drive the discharge pipe 33 to rotate, so as to evenly pour the beverage in the pouring hopper 32 onto the screen 22 of the screening barrel 21, completing the addition of the beverage.

[0096] After the beverage is poured in, the rotation direction of the drive mechanism 51 is changed, driving the first rotating rod 52 to rotate in the first direction, which in turn drives the first bevel gear 531 to rotate, thereby realizing the rotation of the screening tank 21. At the same time, under the series of transmission actions of the second transmission assembly 54, the third transmission assembly 55, the fourth transmission assembly 56, and the fifth transmission assembly 57, the feed pipe 31 and the discharge pipe 33 are also in a rotating state. The regulating valve 46 is opened to allow water to flow to the second water supply pipe 43, so that the fermented milk and fruit particles adhering to the inner wall of the pouring bucket 32 ​​fall into the screening tank 21, while simultaneously performing preliminary cleaning of the fruit particles.

[0097] After the beverage in the pouring bucket 32 ​​has completely fallen into the screening bucket 21, the regulating valve 46 can be adjusted to make the water flow to the first water supply pipe 41. The water flows through multiple nozzles 42 and sprays onto the fruit particles on the screen 22. At the same time, since the drive mechanism 51 is in operation, the first water supply pipe 41 will swing back and forth relative to the vertical plane to improve the rinsing effect on the fruit particles.

[0098] During the cleaning process, the electromagnet 111 is activated. As the sieving drum 21 rotates, the first magnetic element 221 on the bottom side of the screen 22 continuously moves closer to or further away from one of the electromagnets 111. When the first magnetic element 221 aligns with the left electromagnet 111, it tilts the screen 22 to the left, causing the fruit pieces to roll to the left. As the first magnetic element 221 moves away from the left electromagnet 111, the screen 22 returns to a horizontal state under the elastic force of the elastic element 232. When the first magnetic element 221 aligns with the right electromagnet 111, it tilts the screen 22 to the right, causing the fruit pieces to roll to the right. As the first magnetic element 221 moves away from the right electromagnet 111, the screen 22 returns to a horizontal state under the action of the elastic element 232. Simultaneously, the vibration mechanism remains active, and the screen 22 vibrates continuously. Combined with the left and right rolling of the fruit pieces, this effectively prevents the fruit pieces from clogging the screen 22 and further improves the cleaning effect.

[0099] During the washing and sieving process, the separated fermented milk and the water from washing the fruit particles flow sequentially through the sieving bucket 21 and the through holes on the fixed plate 11, and are discharged from the fixed chamber 10 through the drain pipe 17.

[0100] After washing and screening, the telescopic mechanism 214 is extended and retracted to separate the stop block 213 from the discharge port 212. Then, the electromagnet 111 is energized and adjusted to a magnetic state. The first magnetic element 221 attracts the electromagnet 111 on the left, causing the screen 22 to tilt to the left. The fruit pieces fall along the tilted screen 22 through the inclined tube 215 onto the inclined plate 15, and are then removed through the discharge port 16.
