Description

Technical Field

[0001] The invention relates to the technical field of food processing equipment, and in particular to a centrifugal stratified separation mechanism and food processing equipment based on the mechanism. Background Art

[0002] In the process of food processing, the solid food raw materials are usually mixed by centrifugal processing. Especially for the processing of solid food raw materials in a liquid-solid mixed state, centrifugal stirring and mixing are required to make the liquid and solid fully mixed.

[0003] In the prior art, for foods in a liquid-solid mixed state, the solid food and the liquid need to be mixed and stirred with each other, and then the solid food and the liquid are fully mixed. However, in the prior art, there is a phenomenon that the liquid is unevenly dispersed in the solid food, which results in a poor mixing effect and ultimately poor food quality. For this reason, we provide a centrifugal stratification separation mechanism and a food processing equipment based on the mechanism to solve the above problems. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides a centrifugal stratified separation mechanism and a food processing equipment based on the mechanism, which adds the preliminarily mixed mixed material into the interior of a centrifugal barrel and evenly sprays it out from the dispersion holes on the centrifugal barrel, thereby further dispersing the liquid so that the liquid is mixed more evenly inside the solid food raw material, and the mixed material entering the annular storage trough can be further homogenized under the stirring and breaking action of the rake teeth, so that the food is mixed more thoroughly, and the mixed food can be discharged from the discharge pipe.

[0005] In order to achieve the above object, the centrifugal layered separation mechanism used in the present invention comprises:

[0006] An upper cylinder, a lower cylinder and a centrifugal bucket, wherein the upper cylinder is located above the lower cylinder, and the upper cylinder and the lower cylinder are fixedly connected by a U-shaped connecting rod, a slit is provided between the upper cylinder and the lower cylinder, a centrifugal bucket is provided inside the upper cylinder and the lower cylinder, a retaining ring is fixedly provided on the inner wall of the top edge of the centrifugal bucket, dispersion holes are evenly provided on the outer wall of the centrifugal bucket, dispersion rods are evenly provided on the inner wall of the centrifugal bucket, the bottom of the centrifugal bucket is fixedly connected to the rotating shaft of the first drive motor, the first drive motor is fixedly installed at the center position of the bottom of the lower cylinder, a feeding port is provided on the top of the upper cylinder above the centrifugal bucket, food enters the centrifugal bucket from the feeding port and is evenly thrown out from the dispersion holes to the inside of the upper cylinder through centrifugal action;

[0007] An annular material storage trough is fixedly provided inside the lower cylinder below the centrifugal barrel, a discharge pipe is fixedly provided at the bottom of the annular material storage trough, and the discharge pipe extends out of the bottom of the lower cylinder. Rake teeth are provided inside the annular material storage trough, and the rotation of the rake teeth is controlled by a driving mechanism. The rake teeth will fall into the food annular material storage trough to fully disperse and mix the food.

[0008] In this embodiment, the mixed material of the solid food raw material and the liquid is poured into the interior of the centrifugal barrel from the feeding port. At this time, the first driving motor drives the centrifugal barrel to rotate, and the mixed material entering the interior of the centrifugal barrel will be thrown out from the dispersion hole under the action of centrifugal force and enter the interior of the annular storage tank. At this time, the driving mechanism will drive the rake teeth to rotate evenly inside the annular storage tank, and then the mixed material inside the annular storage tank can be stirred again, so that the mixing is more thorough;

[0009] The present invention adds the preliminarily mixed mixed material into the interior of the centrifugal barrel and sprays it out uniformly from the dispersion holes on the centrifugal barrel, thereby further dispersing the liquid so that the liquid is mixed more uniformly inside the solid food raw material, and the mixed material entering the annular storage tank can be further homogenized under the stirring and breaking action of the rake teeth, so that the food is mixed more thoroughly, and the mixed food can be discharged from the discharge pipe;

[0010] At the same time, the dispersion rods on the inner wall of the centrifugal barrel can preliminarily disperse the mixed materials, making the mixing effect better.

[0011] As a further optimization of the above scheme, the driving mechanism includes an outer gear ring and a circular gear plate. The outer gear ring is located in the narrow gap between the upper cylinder and the lower cylinder. The outer gear ring and the circular gear plate are meshed with each other for transmission. The circular gear plate is located outside the upper cylinder and the lower cylinder, and the bottom center position of the circular gear plate is fixedly connected to the rotating shaft of the second drive motor. The second drive motor is installed on the outer wall of the lower cylinder through a mounting plate.

[0012] In this embodiment, the second drive motor drives the circular gear plate to rotate in the horizontal plane, and the circular gear plate and the outer gear ring are engaged with each other to drive the outer gear ring to rotate. When the outer gear ring rotates, it will drive the rake teeth to rotate inside the annular storage trough through the horizontal rod. The rake teeth can stir the mixed materials inside the annular storage trough, thereby improving the mixing effect of the food.

[0013] As a further optimization of the above solution, the central axis of the upper cylinder coincides with the central axis of the lower cylinder and the center of the outer gear ring.

[0014] Specifically, the outer gear ring can rotate around the central axis of the upper cylinder, so that the rake teeth can move smoothly and evenly inside the annular storage tank, so that the rake teeth can stir the mixed material inside the annular storage tank more smoothly.

[0015] As a further optimization of the above solution, the bottom edge of the upper cylinder and the top edge of the lower cylinder are both provided with annular grooves, and the annular grooves are slidably connected to the annular protrusions fixedly provided on the upper and lower surfaces of the outer gear ring.

[0016] In the device, the annular groove and the annular protrusion are slidably connected to each other, which plays a role in limiting the outer gear ring between the upper cylinder and the lower cylinder, so that the rotation of the outer gear ring between the upper cylinder and the lower cylinder is more stable.

[0017] As a further optimization of the above solution, the centrifugal bucket is designed as a truncated cone structure, and the outer diameter of the upper port of the centrifugal bucket is larger than the bottom diameter of the centrifugal bucket.

[0018] Among them, the frustum-shaped design of the centrifuge barrel allows the mixed material inside the centrifuge barrel to climb along the inner wall of the centrifuge barrel during the rotation of the centrifuge barrel. During the climbing process, the dispersion rods on the inner wall of the centrifuge barrel can play a role in preliminarily breaking up and stirring the mixed material, so that the liquid is more evenly distributed inside the solid food raw material.

[0019] As a further optimization of the above scheme, the cross-section of the annular storage trough is designed as a semicircular arc structure, the outer end edge of the annular storage trough is fixedly connected to the inner wall of the lower cylinder, and the inner end edge of the annular storage trough is located in the annular groove at the bottom of the centrifugal barrel.

[0020] The inner end edge of the annular material storage groove is located in the annular groove at the bottom of the centrifugal bucket, which can limit the rotation of the centrifugal bucket, making the rotation of the centrifugal bucket more stable.

[0021] As a further optimization of the above solution, a plurality of groups of supporting legs are fixedly provided at the bottom of the lower cylinder, and the length of the discharge pipe extending out of the bottom of the lower cylinder is less than the height of the supporting legs.

[0022] Specifically, the supporting legs support the lower cylinder body. When unloading, the valve on the discharge pipe can be opened, and the collection bucket can be placed under the discharge pipe for collection.

[0023] As a further optimization of the above scheme, the rake teeth include a connecting rod fixedly welded to the lower surface of the end of the horizontal rod, a plurality of groups of supporting round rods are fixedly arranged on the lower surface of the connecting rod, a rotating sleeve is provided on the supporting round rod, a plurality of groups of crushing teeth distributed in a circular array are fixedly arranged on the outer surface of the rotating sleeve, and the lower end of the supporting round rod is connected to a limit nut movably restricted on the lower surface of the rotating sleeve through threaded cooperation.

[0024] In this embodiment, when the rake teeth rotate and stir in the annular material storage trough, the rotating sleeve on the supporting round rod will rotate around the supporting round rod as the axis due to the action of inertia. When the rotating sleeve rotates, it will squeeze and scrape the food in the mixed material, so that large particles of solid food will be hit and broken by the crushing teeth, thereby allowing the solid food and liquid to be better mixed.

[0025] As a further optimization of the above scheme, a vertically distributed supporting circular shaft is fixedly welded to the inner bottom end of the centrifugal barrel, a rotating ring is rotatably connected to the supporting circular shaft, a lifting and mixing plate is fixedly provided at the outer ring of the rotating ring, the outer ring of the lifting and mixing plate is inclined downward, and the upper end of the supporting circular shaft is connected to a limit ring blocking the top of the rotating ring through threaded cooperation.

[0026] It should be noted that when the centrifugal barrel rotates, the lifting mixing plate will rotate and rise on the supporting circular shaft due to the centrifugal effect, so that the material in the centrifugal barrel is pushed up and down by the lifting mixing plate to be mixed, and the centrifugal barrel can rotate intermittently to adapt to the lifting and lowering of the lifting mixing plate. The mixed material before centrifugation will be pushed up and down to be fully mixed again, and when the lifting mixing plate pushes the solid food up and down, the solid food will fully absorb the liquid, break and disperse in the liquid, and it is not easy to produce large particles of solid food raw materials.

[0027] The invention also discloses a food processing device, comprising any of the above-mentioned centrifugal stratified separation mechanisms.

[0028] The centrifugal layered separation mechanism of the present invention and the food processing equipment based on the mechanism have the following beneficial effects:

[0029] 1. The centrifugal layered separation mechanism of the present invention adds the preliminarily mixed mixed material into the interior of the centrifugal barrel and sprays it out uniformly from the dispersion holes on the centrifugal barrel, thereby further dispersing the liquid so that the liquid is mixed more uniformly inside the solid food raw material, and the mixed material entering the annular storage tank can be further homogenized under the stirring and breaking action of the rake teeth, so that the food is mixed more thoroughly, and the mixed food can be discharged from the discharge pipe;

[0030] 2. In the centrifugal stratified separation mechanism of the present invention, the second driving motor drives the circular gear plate to rotate in the horizontal plane, the circular gear plate and the outer gear ring are meshed with each other to drive the outer gear ring to rotate, and when the outer gear ring rotates, it will drive the rake teeth to rotate inside the annular storage tank through the horizontal rod, and the rake teeth can stir the mixed materials inside the annular storage tank, thereby achieving a better mixing effect of the food;

[0031] 3. In the centrifugal stratified separation mechanism of the present invention and the food processing equipment based on the mechanism, the annular groove and the annular protrusion are slidably connected to each other, which plays a role in limiting the outer gear ring between the upper cylinder and the lower cylinder, so that the rotation of the outer gear ring between the upper cylinder and the lower cylinder is more stable.

[0042] Please refer to the instruction manual Figure 1-5 The present invention provides a technical solution: a centrifugal layered separation mechanism, comprising:

[0043] An upper cylinder 1, a lower cylinder 2 and a centrifugal bucket 5, wherein the upper cylinder 1 is located above the lower cylinder 2, and the upper cylinder 1 and the lower cylinder 2 are fixedly connected by a U-shaped connecting rod 9, a slit is provided between the upper cylinder 1 and the lower cylinder 2, a centrifugal bucket 5 is provided inside the upper cylinder 1 and the lower cylinder 2, a retaining ring 4 is fixedly provided on the inner wall of the top edge of the centrifugal bucket 5, a dispersion hole 6 is evenly provided on the outer wall of the centrifugal bucket 5, a dispersion rod 23 is evenly provided on the inner wall of the centrifugal bucket 5, the bottom of the centrifugal bucket 5 is fixedly connected to the rotating shaft of the first drive motor 7, the first drive motor 7 is fixedly installed at the center position of the bottom of the lower cylinder 2, the top of the upper cylinder 1 is located above the centrifugal bucket 5 and is provided with a feeding port 3, food enters the centrifugal bucket 5 from the feeding port 3 and is evenly thrown out from the dispersion hole 6 to the inside of the upper cylinder 1 through centrifugal action;

[0044] An annular material storage trough 8 is fixedly provided inside the lower cylinder 2 below the centrifugal barrel 5, a discharge pipe 21 is fixedly provided at the bottom of the annular material storage trough 8, and the discharge pipe 21 extends out of the bottom of the lower cylinder 2. Rake teeth 12 are provided inside the annular material storage trough 8, and the rotation of the rake teeth 12 is controlled by a driving mechanism. The rake teeth 12 will fall into the food annular material storage trough 8 to fully disperse and mix the food.

[0045] In this embodiment, the mixed material of the solid food raw material and the liquid is poured into the interior of the centrifugal barrel 5 from the feeding port 3. At this time, the first driving motor 7 drives the centrifugal barrel 5 to rotate, and the mixed material entering the interior of the centrifugal barrel 5 will be thrown out from the dispersion hole 6 under the action of centrifugal force and enter the interior of the annular storage tank 8. At this time, the driving mechanism will drive the rake teeth 12 to rotate evenly inside the annular storage tank 8, and then the mixed material inside the annular storage tank 8 can be stirred again, so that the mixing is more thorough;

[0046] The present invention adds the preliminarily mixed mixed material into the centrifugal barrel 5 and uniformly sprays it out from the dispersion holes 6 on the centrifugal barrel 5, thereby further dispersing the liquid so that the liquid is more uniformly mixed inside the solid food raw material, and the mixed material entering the annular storage tank 8 can be further homogenized under the stirring and breaking action of the rake teeth 12, so that the food is mixed more thoroughly, and the mixed food can be discharged from the discharge pipe 21;

[0047] At the same time, the dispersion rods 23 on the inner wall of the centrifugal barrel 5 can preliminarily disperse the mixed material, so that the mixing effect is better.

[0048] The driving mechanism includes an outer gear ring 10 and a circular gear plate 15. The outer gear ring 10 is located in the slit between the upper cylinder 1 and the lower cylinder 2. The outer gear ring 10 and the circular gear plate 15 are meshed with each other for transmission. The circular gear plate 15 is located outside the upper cylinder 1 and the lower cylinder 2, and the bottom center position of the circular gear plate 15 is fixedly connected to the rotating shaft of the second driving motor 22. The second driving motor 22 is installed on the outer wall of the lower cylinder 2 through the mounting plate 16.

[0049] In the device, the second driving motor 22 drives the circular gear plate 15 to rotate in the horizontal plane, and the circular gear plate 15 and the outer gear ring 10 are meshed with each other to drive the outer gear ring 10 to rotate. When the outer gear ring 10 rotates, it will drive the rake teeth 12 to rotate inside the annular storage trough 8 through the horizontal rod 14. The rake teeth 12 can stir the mixed materials inside the annular storage trough 8, thereby improving the mixing effect of the food.

[0050] The central axis of the upper cylinder 1 coincides with the central axis of the lower cylinder 2 and the center of the outer gear ring 10 .

[0051] The outer gear ring 10 can rotate around the central axis of the upper cylinder 1, so that the rake teeth 12 can move smoothly and evenly inside the annular storage tank 8, so that the rake teeth 12 can stir the mixed material inside the annular storage tank 8 more smoothly.

[0052] The bottom edge of the upper cylinder 1 and the top edge of the lower cylinder 2 are both provided with an annular groove 17, and the annular groove 17 and the annular protrusions 18 fixedly provided on the upper and lower surfaces of the outer gear ring 10 are slidably connected to each other.

[0053] The annular groove 17 and the annular protrusion 18 are slidably connected to each other, which plays a role in limiting the outer gear ring 10 between the upper cylinder 1 and the lower cylinder 2, so that the rotation of the outer gear ring 10 between the upper cylinder 1 and the lower cylinder 2 is more stable.

[0054] The centrifugal barrel 5 is designed to be a truncated cone structure, and the outer diameter of the upper port of the centrifugal barrel 5 is larger than the bottom diameter of the centrifugal barrel 5 .

[0055] The truncated cone design of the centrifugal barrel 5 allows the mixed material inside the centrifugal barrel 5 to climb along the inner wall of the centrifugal barrel 5 during the rotation of the centrifugal barrel 5. During the climbing process, the dispersion rods 23 on the inner wall of the centrifugal barrel 5 can play a role in preliminarily breaking up and stirring the mixed material, so that the liquid is more evenly distributed inside the solid food raw material.

[0056] The cross section of the annular material storage groove 8 is designed as a semicircular arc structure. The outer end edge of the annular material storage groove 8 is fixedly connected to the inner wall of the lower cylinder 2, and the inner end edge of the annular material storage groove 8 is located in the annular groove 19 at the bottom of the centrifugal bucket 5.

[0057] The inner end edge of the annular material storage groove 8 is located in the annular groove 19 at the bottom of the centrifugal bucket 5, which can limit the rotation of the centrifugal bucket 5, making the rotation of the centrifugal bucket 5 more stable.

[0058] A plurality of groups of supporting legs 11 are fixedly provided at the bottom of the lower cylinder 2, and the length of the feeding tube 21 extending out of the bottom of the lower cylinder 2 is less than the height of the supporting legs 11.

[0059] Specifically, the support legs 11 support the lower cylinder 2. When unloading, the valve on the discharge pipe 21 can be opened, and the collection bucket can be placed under the discharge pipe 21 to collect materials.

[0060] The rake teeth 12 include a connecting rod 25 fixedly welded to the lower surface of the end of the horizontal rod 14, a plurality of groups of supporting round rods 29 are fixedly arranged on the lower surface of the connecting rod 25, a rotating sleeve 26 is rotatably sleeved on the supporting round rod 29, a plurality of groups of crushing teeth 27 distributed in a circular array are fixedly arranged on the outer surface of the rotating sleeve 26, and the lower end of the supporting round rod 29 is connected to a limiting nut 28 that is movably restricted on the lower surface of the rotating sleeve 26 through threaded cooperation.

[0061] In this embodiment, when the rake teeth 12 rotate and stir in the annular material storage trough 8, the rotating sleeve 26 on the supporting round rod 29 will rotate around the supporting round rod 29 as the axis due to the action of inertia. When the rotating sleeve 26 rotates, it will squeeze and scrape the food in the mixed material, so that large particles of solid food will be hit and broken by the crushing teeth 27, so that the solid food and liquid are better mixed.

[0062] A vertically distributed supporting circular shaft 24 is fixedly welded to the inner bottom end of the centrifugal barrel 5, and a rotating ring 31 is rotatably connected to the supporting circular shaft 24. A lifting mixing plate 32 is fixedly provided on the outer circle of the rotating ring 31. The outer circle of the lifting mixing plate 32 is inclined downward, and the upper end of the supporting circular shaft 24 is connected to a limiting ring 30 that blocks the upper part of the rotating ring 31 through threaded cooperation.

[0063] It should be noted that when the centrifugal barrel 5 rotates, the lifting mixing plate 32 will rotate and rise on the supporting circular shaft 24 due to the phenomenon of centrifugal action, so that the material in the centrifugal barrel 5 is pushed up and down by the lifting mixing plate 32 for mixing, and the centrifugal barrel 5 can be rotated intermittently to adapt to the lifting and lowering of the lifting mixing plate 32. The mixed material before centrifugation will be pushed up and down to be fully mixed again, and when the lifting mixing plate 32 pushes the solid food up and down, the solid food will fully absorb the liquid, break and disperse in the liquid, and it is not easy to produce large particles of solid food raw materials.

[0064] The present invention also discloses a food processing device, comprising any one of the above-mentioned centrifugal stratified separation mechanisms.

[0065] The centrifugal stratified separation mechanism and the food processing equipment based on the mechanism provided in this embodiment work as follows:

[0066] During operation, the mixed material of the solid food raw material and the liquid is poured into the interior of the centrifugal barrel 5 from the feeding port 3. At this time, the first driving motor 7 drives the centrifugal barrel 5 to rotate. The mixed material entering the interior of the centrifugal barrel 5 will be thrown out from the dispersion hole 6 under the action of centrifugal force and enter the interior of the annular storage tank 8. At this time, the driving mechanism will drive the rake teeth 12 to rotate evenly inside the annular storage tank 8, and then the mixed material inside the annular storage tank 8 can be stirred again, so that the mixing is more thorough.

[0067] The present invention adds the preliminarily mixed mixed material into the centrifugal barrel 5 and uniformly sprays it out from the dispersion holes 6 on the centrifugal barrel 5, thereby further dispersing the liquid so that the liquid is more uniformly mixed inside the solid food raw material, and the mixed material entering the annular storage tank 8 can be further homogenized under the stirring and breaking action of the rake teeth 12, so that the food is mixed more thoroughly, and the mixed food can be discharged from the discharge pipe 21;

[0068] At the same time, the dispersion rods 23 on the inner wall of the centrifugal barrel 5 can preliminarily disperse the mixed material, so that the mixing effect is better.

[0069] It is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
