Description

Technical Field

[0001] This utility model relates to the field of solid beverage production technology, specifically to a high-efficiency sieving device for producing cold-soluble solid beverages. Background Technology

[0002] Solid beverages refer to solid products made primarily from sugar, milk and dairy products, eggs or egg products, fruit juice or edible plant extracts, with the addition of appropriate excipients or food additives. Each 100 grams of the finished product contains no more than 5 grams of moisture. They are in powder, granule or block form, such as soy crystal powder, malted milk powder, instant coffee, chrysanthemum crystals, etc. They are classified into three categories: protein-type solid beverages, ordinary solid beverages, and roasted solid beverages (instant coffee).

[0003] The existing technology has the following problems:

[0004] Existing high-efficiency cold-soluble solid beverage production sieving devices have several drawbacks. Firstly, the presence of large powder particles in the solid beverage causes some to accumulate on the sieving disc, requiring regular cleaning. Secondly, the lightweight nature of solid beverages means that re-grinding and re-entering the sieving disc can cause dust to be generated, resulting in floating solid beverage particles flying out through the feed pipe and causing waste. Utility Model Content

[0005] This invention provides a high-efficiency powder sieving device for the production of cold-soluble solid beverages, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A high-efficiency sieving device for producing cold-soluble solid beverages includes a sieving body, a feed pipe at the top of the sieving body, a discharge pipe fixedly connected to the bottom of the sieving body, a shaking chamber on the inner wall of the sieving body, hydraulic buffer rods fixedly connected to the four corners of the inner wall of the shaking chamber, a support plate rotatably connected to the output end of the hydraulic buffer rods, and a sieving disc fixedly connected to one end of the support plate.

[0008] A fixed rod is fixedly connected to one end of the inner wall of the shaking chamber away from the hydraulic buffer rod. One end of the fixed rod is rotatably connected to a limit rod, and one end of the limit rod is slidably connected to the top of the support plate.

[0009] A collection tube is fixedly connected to the center of the inner wall of the powder sieving disc, a motor is fixedly connected to the bottom of the collection tube, and a deflection ball is fixedly connected to the output end of the motor.

[0010] A further improvement of this utility model is that: a support frame is fixedly connected to the inner wall of the feed pipe, a blower is fixedly connected to the bottom of the support frame, and a suction pipe is fixedly connected to the input end of the blower.

[0011] A further improvement of this utility model is that: a feeding pipe is fixedly connected to the output ends on both sides of the outer wall of the exhaust fan, and a baffle is fixedly connected to one end of the feeding pipe.

[0012] A further improvement of this utility model is that: a grinding disc is attached to the outer wall of the material extraction pipe, and several grinding pipes are fixedly connected to the bottom of the inner wall of the grinding disc.

[0013] A further improvement of this utility model is that a closing push plate is slidably connected to the inner wall of the grinding disc, and the bottom of the closing push plate overlaps with the outer wall of the grinding tube.

[0014] A further improvement of this utility model is that: electric telescopic rods are fixedly connected to the four corners of the bottom of the support frame, and the output end of the electric telescopic rods is fixedly connected to the top of the closing push plate.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a high-efficiency sieving device for the production of cold-soluble solid beverages. A grinding disc is installed on the outer wall of the feeding pipe, and several grinding tubes are installed at the bottom of the inner wall of the grinding disc. Because the surface of the grinding tubes is relatively rough and forms an angle with the contact surface of the sieving disc, when larger solid beverage particles enter the bottom of the grinding disc through the gaps, the friction generated between the sieving disc and the grinding tubes grinds the solid beverage, reducing the particle size so that it passes through the grinding disc and falls into the collection tube located at the center of the inner wall of the sieving disc for storage. This further solves the problem of traditional high-efficiency sieving devices for the production of cold-soluble solid beverages where, during use, larger powder particles mixed in with the solid beverage cause some solid beverage to accumulate on the surface of the sieving disc, requiring operators to clean the sieving disc regularly.

[0017] 2. This utility model provides a high-efficiency sieving device for the production of cold-soluble solid beverages. A support frame is installed on the inner wall of the feed pipe, and the support frame is used to fix a blower installed at its bottom. A suction pipe is installed at the input end of the blower, with one end inserted into a collection pipe. When the blower is started, the ground solid beverage in the collection pipe is drawn into the blower. Feeding pipes are installed at the output ends on both sides of the outer wall of the blower, allowing the solid beverage to be discharged back into the sieving disc along the feeding pipes. To prevent the solid beverage from being blown into the sieving disc and causing dust, a baffle is installed at one end of the feeding pipe to buffer the blown-out solid beverage and reduce the impact of air on the solid beverage. This further solves the problem that in traditional high-efficiency sieving devices for the production of cold-soluble solid beverages, due to the light volume of the solid beverage, the re-blowing of the ground solid beverage back into the sieving disc easily causes dust, resulting in floating solid beverage flying out along the feed pipe and causing waste.

[0024] The present invention will be further described in detail below with reference to embodiments: Example

[0025] like Figure 1-5As shown, this utility model provides a high-efficiency sieving device for the production of cold-soluble solid beverages, including a sieving body 1, a feed pipe 2 at the top of the sieving body 1, a discharge pipe 3 fixedly connected to the bottom of the sieving body 1, a shaking chamber 4 on the inner wall of the sieving body 1, hydraulic buffer rods 5 fixedly connected to the four corners of the inner wall of the shaking chamber 4, a support plate 6 rotatably connected to the output end of the hydraulic buffer rod 5, a sieving disc 7 fixedly connected to one end of the support plate 6, a fixing rod 8 fixedly connected to the end of the inner wall of the shaking chamber 4 away from the hydraulic buffer rod 5, a limit rod 9 rotatably connected to one end of the fixing rod 8, a limit rod 9 slidably connected to the top of the support plate 6, a collection pipe 10 fixedly connected to the center of the inner wall of the sieving disc 7, a motor 11 fixedly connected to the bottom of the collection pipe 10, and a deflection ball 12 fixedly connected to the output end of the motor 11.

[0026] In this embodiment, solid beverage is poured into the powder sieving body 1 through the feed pipe 2 at the top, causing the powder to settle in the powder sieving disc 7 on the inner wall of the shaking chamber 4. A collection pipe 10 is installed at the center of the inner wall of the powder sieving disc 7, and a motor 11 is installed at the bottom of the collection pipe 10. The motor 11 drives the deflection ball 12 installed at its output end to rotate, thereby using the centrifugal force generated during the rotation of the deflection ball 12 to drive the powder sieving disc 7 to move in a uniform circular motion. Fixing rods 8 are installed at the top of the four corners of the inner wall of the shaking chamber 4, and limiting rods 9 are installed at one end of the fixing rods 8. The limiting rods 9 support the support plates 6 installed at the four corners of the outer wall of the powder sieving disc 7. Since the deflection ball 12 generates a large force during rotation, hydraulic buffer rods 5 are installed at the bottom of the four corners of the inner wall of the shaking chamber 4. The hydraulic buffer rod 5 buffers the force generated during the deflection of the sieving disc 7, and the force generated when the hydraulic buffer rod 5 returns to its original position causes the sieving disc 7 to vibrate, thereby accelerating the speed at which the solid beverage passes through the sieving disc 7. Larger particles in the solid beverage will roll along the inclined surface of the sieving disc 7 into the gap between the grinding disc 18 and the sieving disc 7. After being ground and crushed by the grinding disc 18, the solid beverage particles are reduced in size and pass through the grinding disc 18, falling into the collection pipe 10 set in the center of the inner wall of the sieving disc 7 for storage. This further solves the problem that in the traditional high-efficiency cold-soluble solid beverage production sieving device, due to the presence of large powder particles mixed in the solid beverage, some solid beverage will accumulate on the surface of the sieving disc, requiring operators to clean the sieving disc regularly. Example

[0027] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a support frame 13 is fixedly connected to the inner wall of the feed pipe 2, a blower 14 is fixedly connected to the bottom of the support frame 13, a suction pipe 15 is fixedly connected to the input end of the blower 14, a feeding pipe 16 is fixedly connected to the output ends on both sides of the outer wall of the blower 14, and a baffle 17 is fixedly connected to one end of the feeding pipe 16.

[0028] In this embodiment, a support frame 13 is provided on the inner wall of the feed pipe 2, and the support frame 13 is used to fix the exhaust fan 14 at its bottom. A suction pipe 15 is provided at the input end of the exhaust fan 14, and one end of the suction pipe 15 is inserted into the collection pipe 10. When the exhaust fan 14 is started, the ground solid beverage in the collection pipe 10 is drawn into the exhaust fan 14. Feeding pipes 16 are provided at the output ends on both sides of the outer wall of the exhaust fan 14, so that the solid beverage is discharged back into the sieving tray 7 along the feeding pipes 16. This is to prevent the solid beverage from being blown into the sieve tray 7. In the sieving pan 7, dust is generated from the solid beverage inside. Therefore, a baffle 17 is installed at one end of the feeding pipe 16 to buffer the blown solid beverage and reduce the impact of air on the solid beverage. This further solves the problem that in the traditional high-efficiency cold-soluble solid beverage production sieving device, due to the light volume of the solid beverage, the solid beverage after secondary grinding is easily blown back into the sieving pan, causing dust to be generated. This results in the floating solid beverage flying out along the feeding pipe, thus causing waste. Example

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a grinding disc 18 is attached to the outer wall of the material extraction pipe 15, and a plurality of grinding pipes 19 are fixedly connected to the bottom of the inner wall of the grinding disc 18.

[0030] In this embodiment, a grinding disc 18 is provided on the outer wall of the feeding pipe 15, and several grinding tubes 19 are provided at the bottom of the inner wall of the grinding disc 18. Since the surface of the grinding tubes 19 is relatively rough and forms an angle with the contact surface of the sieving disc 7, when larger solid beverage particles enter the bottom of the grinding disc 18 through the gaps, the friction generated between the sieving disc 7 and the grinding tubes 19 is used to grind the solid beverage. When the volume of the solid beverage decreases, some of the solid beverage is discharged through the gaps of the sieving disc 7, while the remaining part falls into the collection pipe 10 for collection along the inclined surface of the sieving disc 7. Example

[0031] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a closed push plate 20 is slidably connected to the inner wall of the grinding disc 18, the bottom of the closed push plate 20 overlaps with the outer wall of the grinding tube 19, and an electric telescopic rod 21 is fixedly connected to the four corners of the bottom of the support frame 13, and the output end of the electric telescopic rod 21 is fixedly connected to the top of the closed push plate 20.

[0032] In this embodiment, the position of the closed push plate 20 within the grinding disc 18 is controlled by the electric telescopic rods 21 installed at the four corners of the bottom of the support frame 13. When the grinding disc 18 needs to be cleaned, the electric telescopic rods 21 are activated, causing the gap at the bottom of the closed push plate 20 to engage with the grinding tube 19 installed at the bottom of the inner wall of the grinding disc 18, thus removing the solid beverage adhering to the surface of the grinding tube 19. This further solves the problem that, during the use of traditional high-efficiency cold-soluble solid beverage sieving devices, due to the stickiness of solid beverages, some solid beverages tend to stick to the surface of the grinding tubes during grinding, which over time leads to the accumulation of solid beverages in the gaps between the grinding tubes, resulting in the waste of raw materials.

[0033] The working principle of this high-efficiency cold-soluble solid beverage production sieving device will be explained in detail below.

[0034] like Figure 1-5As shown, solid beverage is poured into the powder sieving body 1 through the feed pipe 2 at the top, causing the powder to settle in the powder sieving disc 7 on the inner wall of the shaking chamber 4. A collection pipe 10 is installed at the center of the inner wall of the powder sieving disc 7, and a motor 11 is installed at the bottom of the collection pipe 10. The motor 11 drives the deflection ball 12 installed at its output end to rotate, thereby using the centrifugal force generated by the rotation of the deflection ball 12 to drive the powder sieving disc 7 to move in a uniform circular motion. Fixing rods 8 are installed at the top of the four corners of the inner wall of the shaking chamber 4, and limiting rods 9 are installed at one end of the fixing rods 8. The limiting rods 9 support the support plates 6 installed at the four corners of the outer wall of the powder sieving disc 7. Since the deflection ball 12 has a large force during rotation, the supporting plates 6 installed at the bottom of the four corners of the inner wall of the shaking chamber 4 are also supported. The hydraulic buffer rod 5 buffers the force generated during the deflection of the sieving disc 7. The force generated when the hydraulic buffer rod 5 resets causes the sieving disc 7 to vibrate, thereby accelerating the passage of solid beverage through the sieving disc 7. A grinding disc 18 is installed on the outer wall of the extraction pipe 15, and several grinding tubes 19 are installed at the bottom of the inner wall of the grinding disc 18. Because the surface of the grinding tubes 19 is relatively rough and forms an angle with the contact surface with the sieving disc 7, when larger solid beverage particles enter the bottom of the grinding disc 18 through the gaps, the friction generated between the sieving disc 7 and the grinding tubes 19 grinds the solid beverage. As the volume of the solid beverage decreases, some of it is discharged through the gaps in the sieving disc 7, while the remainder flows through the sieving disc 7. The powder falls onto the inclined surface of the collection pipe 10 for collection. This further solves the problem of traditional high-efficiency cold-soluble solid beverage sieving devices accumulating solid beverage particles on the sieving plate surface due to the presence of large powder particles, requiring operators to clean the sieving plate regularly. A support frame 13 is installed on the inner wall of the feed pipe 2, which is used to fix the exhaust fan 14 at its bottom. A suction pipe 15 is installed at the input end of the exhaust fan 14, with one end inserted into the collection pipe 10. The exhaust fan 14 is then activated to draw the ground solid beverage from the collection pipe 10 into the exhaust fan 14. Feed pipes 16 are installed on both sides of the outer wall of the exhaust fan 14 to allow the solid beverage to pass through the collection pipe 10. The solid beverage is re-discharged into the sieving disc 7 via the feeding pipe 16. To prevent solid beverage from being blown into the sieving disc 7 and causing dust, a baffle 17 is installed at one end of the feeding pipe 16. The baffle 17 buffers the blown-out solid beverage, reducing the impact of air on the solid beverage. This further solves the problem that in traditional high-efficiency cold-soluble solid beverage production sieving devices, due to the light volume of solid beverage, dust is easily generated when the re-blown solid beverage after secondary grinding is blown into the sieving disc, causing floating solid beverage to fly out along the feeding pipe and resulting in waste. The position of the closed push plate 20 within the grinding disc 18 is controlled by electric telescopic rods 21 installed at the four corners of the bottom of the support frame 13.When cleaning of the grinding disc 18 is required, the electric telescopic rod 21 is activated, causing the gap at the bottom of the closed push plate 20 to engage with the grinding tube 19 located at the bottom of the inner wall of the grinding disc 18. This removes the solid beverage adhering to the surface of the grinding tube 19, further solving the problem that in traditional high-efficiency cold-soluble solid beverage production sieving devices, due to the stickiness of solid beverages, some of the solid beverage easily adheres to the surface of the grinding tube during grinding, leading to the accumulation of solid beverage in the gaps between the grinding tubes over time, thus wasting raw materials.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
