Description

Technical Field

[0001] This invention belongs to the field of animal slaughtering and processing technology, and in particular relates to an automated cleaning method and equipment for the high-value utilization of animal intestines. Background Technology

[0002] Animal offal is a common byproduct in the industrialized slaughtering and processing of livestock, poultry, and aquatic products. This offal is often further processed into usable products with a broad market demand. Animal intestines are particularly common, including pig intestines, chicken intestines, and duck intestines. However, the processing and utilization of aquatic animal intestines is relatively rare. Nevertheless, in recent years, technologies for processing and utilizing aquatic animal intestines have emerged in large numbers, showing significant development potential.

[0003] A crucial aspect of animal intestine processing is separating the intestinal contents from the intestine itself. These contents, primarily food residue and feces, are difficult to process. A common approach is to cut open the intestines for further processing. However, cutting open the intestines is challenging because they are very soft and resilient, usually requiring processing individually or pre-treatment of the animal, significantly hindering automated processing efficiency. This is especially true for the relatively small and delicate intestines of aquatic animals, where automated removal of contents is even more difficult. After removing the contents, there are numerous techniques for cleaning the intestines, including various methods such as kneading, drum cleaning, high-pressure water rinsing, negative pressure cleaning, and ultrasonic cleaning, among many others.

[0004] Most of the aforementioned animal intestine processing technologies cater to the food market, providing consumers with a specific type of animal intestine product, thus requiring a certain level of visual appeal, such as whole, neatly cut intestines. However, in reality, whole intestines are not always necessary in the final cooking process; often, they need to be cut into palatable sizes before further cooking. Furthermore, many animal intestines contain active substances that can be further processed for high-value utilization. In this case, the appearance of the intestines after processing and cleaning is not the primary concern; rather, more efficient automated cleaning and processing technologies are required. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1 As shown, this invention provides an automated cleaning method for the high-value utilization of animal intestines, comprising the following steps:

[0033] The animal's intestinal wall is perforated using a perforation device;

[0034] The perforated animal intestinal wall is squeezed using a squeezing device;

[0035] The squeezed animal intestinal wall is centrifuged using a centrifuge device. After centrifugation for a certain period of time, the animal intestinal wall is cut inside the centrifuge device.

[0036] The animal's intestinal wall is rinsed using a rinsing device, and then collected using a collection device after rinsing.

[0037] Depending on the cleaning requirements, the above steps can be repeated to meet the animal intestine cleaning needs.

[0038] An automated cleaning device for the high-value utilization of animal intestines is disclosed. The cleaning device is used to implement the aforementioned method. The cleaning device includes a perforating device, the feed end of which is connected to a feed hopper 1, the discharge end of which is connected to a squeezing device, the discharge end of which is connected to a centrifuge device, the bottom of which is connected to a first heavy waste collection area 21, a cutting device inside the centrifuge device, a first animal intestine outlet 17 connected to the side wall of the centrifuge device, the first animal intestine outlet 17 connected to a rinsing device, the top edge of the top surface of the centrifuge device connected to the top of a light material collection channel 18, the first animal intestine outlet 17 connected to the rinsing device, the bottom of which is connected to a second heavy waste collection area 22, the side wall of which is connected to a second animal intestine outlet 19, the second animal intestine outlet 19 connected to a collection device, the top edge of the top surface of the rinsing device connected to the light material collection channel 18, and the top of the feed hopper 1 is provided with a water outlet of a water supply device.

[0039] The scheme is further optimized. The perforating device includes a shell. The top of the shell is connected to the feed hopper 1. Two perforating rollers 3 are rotatably connected inside the shell. The distance between the two perforating rollers 3 is adjusted by a distance adjustment mechanism 4. The distance adjustment mechanism 4 is driven by a drive unit. The discharge end of the shell is connected to the extrusion device.

[0040] The outer wall of the perforating roller 3 is provided with several perforated protrusions. The animal's intestinal wall is punctured by the squeezing of the two perforating rollers 3.

[0041] Two spacing adjustment mechanisms 4 are provided, respectively located at both ends of the perforated roller 3. Each spacing adjustment mechanism 4 includes a mounting housing 401. A double-groove pulley 403 is rotatably connected to the side wall of the mounting housing 401. The double-groove pulley 403 is connected to a first intermediate pulley 409 via a first belt drive. The double-groove pulley 403 is connected to a pulley 404 via a second belt drive. The first intermediate pulley 409 meshes with a second intermediate pulley 410. The first intermediate pulley 409 and the second intermediate pulley 410 are rotatably connected to the side wall of the mounting housing 401. The second intermediate pulley 410 is connected to another pulley 404 via a second belt drive. Two symmetrically arranged arc-shaped grooves 402 are provided on the side wall of the mounting housing 401. The pulley 404 is connected to the perforated roller connecting shaft 405, which is connected to the perforated roller 3. The perforated roller connecting shaft 405 is slidably arranged in the arc-shaped groove 402. The center of the arc of one arc-shaped groove 402 coincides with the center of the double groove pulley 403, and the center of the arc of the other arc-shaped groove 402 coincides with the center of the second intermediate pulley 410. The end of the perforated roller connecting shaft 405 away from the perforated roller 3 extends out of the mounting shell 401 and is connected to the spacing adjustment component. One of the double groove pulleys 403 on the spacing adjustment mechanism 4 on one side is connected to the output shaft of the perforated roller motor 2. The perforated roller motor 2 is fixedly connected to the mounting shell 401. An arc-shaped clearance groove corresponding to the arc-shaped groove 402 is opened on the side wall of the shell.

[0042] The spacing adjustment component is used to adjust the spacing between the two perforated rollers 3 to accommodate the perforation of different animal intestines. The arc center of the arc groove 402 is set to coincide with the axis of the double groove pulley 403 and the second intermediate pulley 410 to ensure that the power transmission of the second belt is not affected when the two perforated rollers 3 slide in the arc groove 402.

[0043] The spacing adjustment assembly includes an adjustment block 406 rotatably connected to the end of the perforated roller connecting shaft 405. One adjustment block 406 is rotatably connected to one end of an adjustment screw 407, and the other adjustment block 406 is threadedly connected to the adjustment screw 407. A first spring 408 is fixedly connected between the two adjustment blocks 406 and is sleeved on the outside of the adjustment screw 407.

[0044] The distance between the two adjusting blocks 406 can be adjusted by rotating the adjusting screw 407. The adjusting blocks 406 can drive the perforated roller 3 to move along the arc-shaped slide 402 to realize the adjustment of the distance between the perforated roller 3. The first spring 408 is there to provide the rebound force when the two adjusting blocks 406 are reset.

[0045] The scheme is further optimized. The extrusion device includes a slide 5, which is inclined. The high end of the slide 5 is connected to the outer shell, and the low end of the slide 5 is connected to the cleaning device. An extrusion roller 29 is rotatably connected inside the slide 5. The extrusion roller 29 is connected to a spacing adjustment part, and one end of the extrusion roller 29 is driven to be connected to an extrusion roller motor 6.

[0046] The spacing adjustment part includes a clearance groove 501 formed on the side wall of the slide rail 5. The two opposite side walls of the slide rail 5 are respectively fixedly connected to slide rails 502. The slide rails 502 are perpendicular to the bottom wall of the slide rail 5. A slider 503 is slidably connected inside the slide rail 502. The output shaft of the extrusion roller motor 6 rotates through the slider 503 and is shaft-connected to the extrusion roller 29. The extrusion roller motor 6 is fixedly connected to the slider 503. A spacing adjustment screw 504 is rotatably connected to one side of the slider 503. The spacing adjustment screw 504 passes through the end side wall of the slide rail 502 and is threadedly connected to the slide rail 502. The axis of the spacing adjustment screw 504 is parallel to the length direction of the slide rail 502. A second spring 505 is fixedly connected between the slider 503 and the end side wall of the slide rail 502. The second spring 505 is sleeved on the outside of the spacing adjustment screw 504.

[0047] By rotating the pitch adjustment screw 504, the pitch adjustment screw 504 drives the slider 503 to move along the slide rail 502. Since the slide rail 502 is perpendicular to the bottom wall of the slide 5, when the slider 503 moves, it can drive the extrusion roller 29 to move, thereby adjusting the gap between the extrusion roller 29 and the bottom wall of the slide 5 to adapt to the extrusion of different animal intestines.

[0048] The centrifuge device further optimizes the design by including a first centrifugal separation cylinder 8. The bottom of the first centrifugal separation cylinder 8 is connected to the first heavy waste accumulation area 21. The upper part of the side wall of the first centrifugal separation cylinder 8 is connected to the first animal intestine outlet 17. The outlet end of the first animal intestine outlet 17 is located above the rinsing device. The light material collection channel 18 is inclined and has a first light waste collection port at its high end. The top edge of the first centrifugal separation cylinder 8 is connected to the first light waste collection port. The side wall of the first centrifugal separation cylinder 8 is connected to the outlet end of the water supply device.

[0049] The scheme is further optimized by installing several underwater cutting electric saws 9 inside the first centrifugal separation cylinder 8. The several underwater cutting electric saws 9 are arranged at equal intervals along the center of the first centrifugal separation cylinder 8, and the several underwater cutting electric saws 9 are connected to the same rotating mechanism.

[0050] The rotating mechanism includes a mounting frame 23, a drive motor 25 is fixedly connected to the top of the mounting frame 23, the output shaft of the drive motor 25 passes through the mounting frame 23 and is connected to a chainsaw mounting frame 24, the chainsaw mounting frame 24 is fixedly connected to several underwater cutting chainsaws 9, and the mounting frame 23 is mounted on the base 15.

[0051] The water inside the first centrifugal separator 8 rotates under centrifugal force. At the same time, the rotation of the drive motor 25 drives several underwater cutting electric saws 9 to rotate. At this time, the animal intestines inside the first centrifugal separator 8 are wrapped around the underwater cutting electric saws 9. Then the underwater cutting electric saws 9 are started to cut the animal intestines. As the water inside the first centrifugal separator 8 rotates, the light waste floats up and enters the light waste collection channel 18 through the first light waste collection port. The animal intestines are discharged into the rinsing device through the first animal intestine outlet 17. The heavy waste is discharged through the first heavy waste collection area 21. The bottom of the first heavy waste collection area 21 is connected to the first valve, and a heavy waste collection box 28 is set below the first valve.

[0052] The scheme is further optimized. The rinsing device includes a centrifugal rinsing separation cylinder 16. The bottom of the centrifugal rinsing separation cylinder 16 is connected to a second heavy waste collection area 22. The upper part of the side wall of the centrifugal rinsing separation cylinder 16 is connected to a second animal intestine outlet 19. The second animal intestine outlet 19 is located above the collection device. The lower end of the light material collection channel 18 is provided with a second light waste collection port. The top edge of the centrifugal rinsing separation cylinder 16 is connected to the second light waste collection port. The side wall of the centrifugal rinsing separation cylinder 16 is connected to the water outlet of the water supply device.

[0053] Driven by the rotating water flow inside the centrifugal rinsing and separating cylinder 16, light waste enters the light material collection channel 18 through the second light waste collection port, animal intestines are discharged into the collection device through the second animal intestine outlet 19, and heavy waste is discharged through the second heavy waste accumulation area 22. The bottom of the second heavy waste accumulation area 22 is connected to a second valve, which is located above the heavy waste collection box 28.

[0054] The scheme is further optimized. The collection device includes an animal intestine storage box 20, which is located below the second animal intestine outlet 19. The animal intestine storage box 20 is equipped with a filter screen inside, and the bottom of the animal intestine storage box 20 is connected to the water supply device.

[0055] Further optimizing the scheme, the water supply device includes a water storage tank 13, inside which is a submersible pump 12. The outlet end of the submersible pump 12 is connected to a circulating water outlet pipe 27. The end of the circulating water outlet pipe 27 away from the submersible pump 12 is connected to a nozzle 26, which is located above the feed hopper 1. The circulating water outlet pipe 27 is connected to one end of a first connecting pipe 10, the other end of which is connected to the side wall of a first centrifugal separator 8. The circulating water outlet pipe 27 is also connected to one end of a second connecting pipe 11, the other end of which is connected to the side wall of a centrifugal rinsing separator 16. The lower end of the lightweight material collection channel 18, away from the second lightweight waste, is provided with a lightweight material discharge port. The bottom end of the animal intestine storage box 20 is connected to one end of a circulating return water pipe 14, the other end of which is connected to the side wall of the water storage tank 13. A lightweight waste collection bucket can be placed below the lower end of the lightweight material collection channel 18 for collecting lightweight waste.

[0056] The axis of the liquid outlet of the first connecting pipe 10 forms an angle with the diameter of the first centrifugal separator 8, and the axis of the liquid outlet of the second connecting pipe 11 forms an angle with the diameter of the centrifugal rinsing separator 16. The configuration of the first connecting pipe 10 and the second connecting pipe 11 provides rotational power to the water in the first centrifugal separator 8 and the centrifugal rinsing separator 16.

[0057] Experimental Example 1:

[0058] Take an automated cleaning device of the present invention, adjust the gap between the perforating roller 3 and the gap between the extrusion roller 29 to 3.60 mm, and set the speed of the drive motor 25 to 1500 rpm. Add an appropriate amount of clean water to the water storage tank 13, the first centrifugal separation cylinder 8, and the centrifugal rinsing separation cylinder 16, reserving sufficient water space to accommodate the volume of pig intestine material. Start the equipment to ensure smooth water circulation.

[0059] Fresh pig intestines collected from slaughtering and processing are gradually added in batches to the feed hopper 1. The intestines are first crushed and perforated by the perforating roller 3, creating a series of holes. Then, the crushed intestines are squeezed by the extrusion roller 29, squeezing out almost all of their contents. Further, under the action of circulating flushing water, all material falls into the first centrifugal separator 8, where the squeezed-out intestines are quickly wrapped and collected by several underwater cutting electric saws 9. The lighter portion of the squeezed-out intestine contents floats on the water surface and is discharged from the first light waste collection port at the top of the first centrifugal separator 8; the heavier portion settles at the bottom of the separator and is discharged from the first heavy waste accumulation area 21 at the bottom of the first centrifugal separator 8; the lost circulating water volume is replenished by the water storage tank 13. The rotation direction of the several underwater cutting electric saws 9 is the same as the flow direction of the rotating flow field of the first centrifugal separator 8. The operating program of the drive motor 25 is set as follows: after running for 80 seconds, the underwater cutting electric saw 9 on the electric saw mounting bracket 24 is started to run for 15 seconds, and then rotated in the opposite direction for 10 seconds.

[0060] The pig intestines collected and entangled on the underwater cutting chainsaw 9 are quickly cut into fragments of approximately 8-20 cm and rapidly detach from the chainsaw. Under the influence of the rotating flow field, they are discharged from the first animal intestine outlet 17 of the first centrifugal separator 8. The operating program of the underwater cutting chainsaw 9 can be adjusted in the central controller according to the actual processing effect. For example, the centrifugal winding and collecting speed and duration of the pig intestines, the saw cutting time, and the reverse rotation time can be gradually adjusted to achieve the best cleaning effect. The height of the discharge ports of the first animal intestine outlet 17 and the second animal intestine outlet 19 can be appropriately adjusted according to the material collection situation and the swirling flow field to achieve the best material collection effect and remove waste to the greatest extent.

[0061] After the above treatment, the pig intestine material falls into the centrifugal rinsing and separation cylinder 16, where it is separated by swirling again. Further rinsing removes waste that is lighter than or heavier than the pig intestine, resulting in very clean small sections of pig intestine about 8-20 cm long being collected in the animal intestine storage box 20. These sections have some holes, but they do not affect further cooking or other processing.

[0062] Based on the actual operation and treatment effect, the gap of the perforated roller 3 and the gap of the extrusion toothed roller can be adjusted appropriately by adjusting the lead screw 407 and the spacing adjustment lead screw 504, and the flow rate and velocity of the circulating water can be adjusted by adjusting the valves to achieve better cleaning treatment effect and ensure cleaning quality.

[0063] In summary, the automated pig intestine processing and cleaning equipment of this embodiment has the following advantages compared with traditional cleaning methods: it can quickly and conveniently remove impurities such as intestinal contents from a large amount of pig intestine by-products and process them into clean small sections of pig intestine about 8-20 cm long. However, it has some holes, which may affect its appearance as a cooked food, but does not affect its edible value.

[0064] If the residue in the pig intestines does not reach the expected level of cleanliness, the cleaned animal intestines can be put back into the feed hopper 1 and the cleaning can be repeated until the requirements are met.

[0065] Experimental Example 2:

[0066] This experimental example demonstrates the high-value utilization of animal intestines through automated cleaning technology and equipment, which is applied to the automated cleaning of poultry intestines, such as the automated processing and cleaning of duck intestines.

[0067] Take an automated cleaning device developed in this invention, adjust the gap between the perforated roller 3 and the gap between the extrusion roller 29 to 2.70 mm, and set the speed of the drive motor 25 to 2000 rpm. Add an appropriate amount of clean water to the water storage tank 13, the first centrifugal separation cylinder 8, and the centrifugal rinsing separation cylinder 16 beforehand, reserving sufficient water space to accommodate the volume of the duck intestine material. Start the device to ensure smooth water circulation.

[0068] Fresh duck intestines collected from slaughtering and processing are gradually added in batches to the feed hopper 1 of the processing equipment. The intestines are first crushed and perforated by the perforating roller 3, creating a series of holes. Then, the crushed intestines are squeezed by the extrusion roller 29, squeezing out almost all of their contents. Further, under the action of circulating flushing water, all material falls into the first centrifugal separator 8, where the squeezed-out intestines are quickly wrapped and collected by several underwater cutting electric saws 9. The lighter portion of the squeezed-out intestine contents floats horizontally and is discharged from the light waste outlet at the top of the centrifugal separator; the heavier portion settles to the bottom and is discharged from the first light waste collection outlet at the top of the first centrifugal separator 8; the lost circulating water volume is replenished by the water storage tank 13. The rotation direction of the several underwater cutting electric saws 9 is the same as the flow direction of the rotating flow field in the first centrifugal separator 8. The operating program of the drive motor 25 is set as follows: after running for 90 seconds, the underwater cutting electric saw 9 on the electric saw mounting bracket 24 is started to run for 10 seconds, and then rotated in the opposite direction for 8 seconds.

[0069] The duck intestines collected and entangled on the underwater cutting chainsaw 9 are quickly cut into fragments of approximately 5-15 cm and detached from the chainsaw. Under the influence of the rotating flow field, they are discharged from the first animal intestine outlet 17 of the first centrifugal separator 8. The operating program of the underwater cutting chainsaw 9 can be adjusted in the central controller according to the actual processing effect. For example, the centrifugal winding and collecting speed and duration of the duck intestines, the saw cutting time, and the reverse rotation time can be gradually adjusted to achieve the best cleaning effect. The heights of the first animal intestine outlet 17 and the second animal intestine outlet 19 can be appropriately adjusted according to the material collection situation and the swirling flow field to achieve the best material collection effect and remove waste to the greatest extent.

[0070] After the above treatment, the duck intestine material falls into the centrifugal rinsing and separation cylinder 16, where it is separated by swirling again. Further rinsing removes waste that is lighter than or heavier than the duck intestine, thus collecting very clean small sections of duck intestine about 5-15 cm long in the animal intestine storage box 20. These sections have some holes, but they do not affect further cooking or other processing.

[0071] Based on the actual operation and treatment effect, the gap of the perforated roller 3 and the gap of the extrusion toothed roller can be adjusted appropriately by adjusting the lead screw 407 and the spacing adjustment lead screw 504, and the flow rate and velocity of the circulating water can be adjusted by adjusting the valves to achieve better cleaning treatment effect and ensure cleaning quality.

[0072] In summary, the automated duck intestine processing and cleaning equipment of this embodiment has the following advantages compared with traditional processing and cleaning methods: it integrates duck intestine processing and cleaning processes, quickly and conveniently removes impurities such as intestinal contents from a large amount of duck intestine by-products, and processes them into clean small sections of duck intestine about 5-15 cm long. However, it has some holes, which may affect its appearance as a hot pot ingredient, but does not affect its actual edible value.

[0073] If the residue inside the duck intestines does not reach the expected level of cleanliness, the cleaned animal intestines can be repeatedly put into feed hopper 1 and cleaned again until the requirements are met.

[0074] Experiment Example 3:

[0075] Please see Figure 1 This embodiment utilizes an automated cleaning process and equipment for the high-value utilization of animal intestines, which is applied to the automated cleaning of aquatic animal intestines, such as the automated processing and cleaning of sea cucumber intestines.

[0076] Take an automated cleaning device developed in this invention, adjust the gap between the perforated roller 3 and the gap between the extrusion roller 29 to 1.20 mm, and set the speed of the drive motor 25 to 1800 rpm. Add an appropriate amount of clean water to the water storage tank 13, the first centrifugal separation cylinder 8, and the centrifugal rinsing separation cylinder 16, reserving sufficient water space to accommodate the volume of sea cucumber intestines. Start the device to ensure smooth water circulation.

[0077] Fresh sea cucumber intestines discarded during sea cucumber processing are collected and gradually added to the feed hopper of the processing equipment in batches. The sea cucumber intestines are first crushed and perforated by a crushing toothed roller, creating a series of holes. Then, the crushed sea cucumber intestines are squeezed by a squeezing roller 29, squeezing out almost all of their contents. Further, under the action of circulating flushing water, all material falls into the first centrifugal separator 8, and the squeezed-out sea cucumber intestines are quickly entangled and collected by several underwater cutting electric saws 9. The squeezed-out sea cucumber intestine contents are divided into two parts: the lighter portion floats on the surface and is discharged from the first light waste collection port at the top of the first centrifugal separator 8; the heavier portion settles at the bottom of the separator and is discharged from the first heavy waste accumulation area 21 at the bottom of the first centrifugal separator 8; the lost circulating water volume is replenished by the water storage tank 13. The rotation direction of the several underwater cutting electric saws 9 is the same as the flow direction of the rotating flow field of the first centrifugal separator 8. The operating program of the drive motor 25 is set as follows: after running for 60 seconds, the underwater cutting electric saw 9 on the electric saw mounting bracket 24 is started to run for 8 seconds, and then rotated in the opposite direction for 5 seconds.

[0078] The sea cucumber intestines collected and entangled on the underwater cutting chainsaw 9 are quickly cut into fragments of approximately 5-15 cm and rapidly detach from the chainsaw. Under the influence of the rotating flow field, they are discharged from the first animal intestine outlet 17 of the first centrifugal separator 8. The operating program of the underwater cutting chainsaw 9 can be adjusted in the central controller according to the actual processing effect. For example, the centrifugal winding and collecting speed and time of the sea cucumber intestines, the duration of saw cutting, and the duration of reverse rotation can be gradually adjusted to achieve the best cleaning effect. The height of the discharge ports of the first animal intestine outlet 17 and the second animal intestine outlet 19 can be appropriately adjusted according to the material collection situation and the swirling flow field to achieve the best material collection effect and remove waste to the greatest extent.

[0079] After the above treatment, the sea cucumber intestine material falls into the centrifugal rinsing and separation cylinder 16, where it undergoes another swirling material separation process. Further rinsing removes waste that is lighter and heavier than the sea cucumber intestine, resulting in the collection of very clean small sections of sea cucumber intestine about 5-15 cm long in the animal intestine storage box 20. These sections have some holes, but they do not affect further cooking or other deep processing.

[0080] Based on the actual operation and treatment effect, the gap of the perforated roller 3 and the gap of the extrusion toothed roller can be adjusted appropriately. The flow rate and velocity of the circulating water can be adjusted by adjusting the valves to achieve a better cleaning effect and ensure the cleaning quality of the sea cucumber intestines.

[0081] If the residue inside the sea cucumber intestines does not reach the expected level of cleanliness, the cleaned animal intestines can be repeatedly put into the feed hopper 1 and cleaned again until the requirements are met.
