Description

Technical Field

[0001] The invention belongs to the technical field of sausage making equipment, and particularly relates to an automatic spray cleaning device for residual stuffing on the surface after meat products are filled into casings. Background Art

[0002] For sausage making, after the meat is ground, it is mixed with auxiliary materials such as blanks, stuffing, and spices, and then injected into casings through a filling machine to obtain sausages. When filling, there will be stuffing adhering to the surface of the filled products, which needs to be cleaned to ensure the cleanliness of the finished products and convenient storage.

[0003] The existing Chinese utility model patent with the publication number CN217065235U discloses a sausage raw material cleaning pool, which performs hierarchical cleaning of raw materials through an adjacent first-level pool and second-level pool, and can also recycle wastewater. However, in actual use, because the stuffing of meat sausages has a large oil content, the clean water flushes from top to bottom and only acts on the upper surface of the raw materials, and the lower surface cannot be directly flushed. Moreover, the cleaning effect of clean water on grease is poor, resulting in the need for more flushing points and a longer cleaning distance, making the overall length of the equipment longer and occupying a larger floor area. In view of this, an automatic spray cleaning device for residual stuffing on the surface after meat products are filled into casings is provided. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide an automatic spray cleaning device for residual stuffing on the surface after meat products are filled into casings.

[0005] The technical solution adopted to solve the above technical problem is as follows: An automatic spray cleaning device for residual stuffing on the surface after meat products are filled into casings, comprising: An immersion tank, the immersion tank includes a main body with an upward opening, the main body is internally provided with a cleaning liquid, a first carrying roller is arranged in the middle of the main body, and second carrying rollers are arranged on both sides of the main body at the first carrying roller, the second carrying rollers are lower than the liquid level of the cleaning liquid, and the first carrying roller is higher than the liquid level of the cleaning liquid; A sprayer, the sprayer includes a first bender and a second bender, the filled products are reciprocally wound between the first bender and the second bender from front to back, the first bender and the second bender are located on both sides of the first carrying roller, a spray plate is respectively arranged directly above the first bender and the second bender, the spray plate generates a vertically downward water flow, and the sprayer further includes a waste discharger, and the waste discharger is installed at the bottom of the front side of the main body; An air spray pipe, the air spray pipe is located at the same height as the first carrying roller, and the air spray pipe generates a vertically upward air flow.

[0006] Further, the waste discharger is arranged below the second carrying roller. A plurality of flushers arranged at equal intervals are installed at the rear side of the main body. The flushers are arranged vertically forward, and the flushers are communicated with a spray plate through a conveying pipe.

[0007] By the above technical solution, to ensure the cleanliness of the cleaning liquid, the flushers continuously supplement new cleaning liquid for the main body from the rear to the front. The old cleaning liquid is discharged by the waste discharger at the front side of the main body and cooperates with the filling product that reciprocally winds from the front to the rear. The discharge position of the old cleaning liquid is close to the newly entered filling product, and the new cleaning liquid is located at the position where the filling product moves out of the main body, making full use of the cleaning liquid and ensuring the cleanliness of the filling product.

[0008] Further, the first bender includes two middle pipes arranged in parallel. The conveying pipe is communicated with the middle pipes through a connector. An annular array of support bars is arranged on the circumferential outer wall of the middle pipes along the axis of the middle pipes. Spray holes arranged at equal intervals are formed on the circumferential outer wall of the middle pipes. The support bars and the spray holes are arranged in a staggered manner. The second bender has the same structure as the first bender.

[0009] By the above technical solution, the filling product is bent at the position of the first bender. The inner diameter position of the bent position of the filling product is supported by the support bars, and the cleaning liquid is sprayed out from the positions of the spray holes, avoiding affecting the cleaning efficiency due to blockage when the filling product bends and changes direction.

[0010] Further, a plurality of blocking disks are arranged at equal intervals along the axis of the middle pipes. The diameter line of the blocking disks is perpendicular to the axis of the middle pipes, and the circumferential side walls of two adjacent blocking disks are in contact with each other.

[0011] By the above technical solution, the blocking disks conduct front-back partition and limit on the filling product, making full use of the length of the middle pipes, enabling the filling product to wind reciprocally as much as possible, and also avoiding the filling products from being wound around each other.

[0012] Further, there are two first carrying rollers, and the air spray pipe is arranged between the two first carrying rollers. The air spray pipe is located above the liquid level of the cleaning liquid.

[0013] By the above technical solution, the filling product passes above the air spray pipe, and the air spray pipe is clamped between the two first carrying rollers, preventing the non-rotating air spray pipe from wearing the casing of the filling product.

[0014] Further, an aggregator is installed directly above the air spray pipe on the main body. The aggregator has an opening facing downward and the opening position is higher than the liquid level of the cleaning liquid. A lead-out shell is provided at the front end of the aggregator.

[0015] Through the above technical solution, when the foam generated in the cleaning liquid passes through the air injection pipe with the filled product, the foam on the surface of the filled product and the emulsified oil are blown off, and contact with the cleaning liquid to complete a more thorough cleaning. The foam is blown into the aggregator, which is convenient for leading out and discharging centrally, preventing the foam from accumulating and affecting the surface cleaning of the filled product that detaches from the main body later.

[0016] Further, the aggregator includes a hollow housing with a narrower upper part and a wider lower part. Fins are fixedly installed on the inner wall of the housing. The free ends of the fins extend obliquely upward to the middle of the housing. The leading-out shell is communicated with the inner space of the housing.

[0017] Through the above technical solution, the housing is trapezoidal with a narrower upper part and a wider lower part. As the foam accumulates in the housing, the fins increase the inner surface area of the housing and squeeze and converge the foam towards the middle, making the foam easier to break.

[0018] Further, a skirt is installed at the position of the bottom edge of the housing. The free end of the skirt extends horizontally, and the lowest point of the skirt is higher than the filled product above the first carrying roller.

[0019] Through the above technical solution, the skirt is at a relatively high position, which does not affect the advancement of the filled product, and can block and collect the foam generated when the filled product enters and exits the cleaning liquid. The skirt guides the foam into the housing for subsequent defoaming operations, improving the defoaming efficiency.

[0020] Further, a top cover is installed at the opening position at the top of the main body. The spray plate is fixedly penetrated through the top cover. Side openings for the filled product to pass through are provided on both sides of the top cover.

[0021] Through the above technical solution, the top cover shields and protects the main body, preventing foreign objects from falling in, and provides an installation position for the spray plate, enabling the spray plate to be suspended directly above the bending position of the filled product to ensure the flushing efficiency. The side openings do not affect the entry and exit of the filled product from the main body.

[0022] Further, an extruder and a knotter are provided at the side opening on the right side of the top cover, and an output rack is provided at the side opening on the left side of the top cover.

[0023] Through the above technical solution, the extruder is filled with meat product stuffing and filled into the casing to form a continuous filled product. When passing through the position of the knotter, a metal ring is installed for knotting to obtain a continuous but internally independent filled product for subsequent spray cleaning. The output rack is used to overhead convey the cleaned filled product for water control while being conveyed.

[0024] The beneficial effects of the present invention are as follows: (1) Through the settings of the soaking pool, the sprayer, and the air injection pipe, the continuously filled products after filling are introduced into the cleaning liquid in the soaking pool. The air injection pipe flushes away the emulsified substances and attachments on the surface of the filled products after they are separated from the cleaning liquid. Along with the rotation of the first bender and the second bender, the filled products are lifted out of the cleaning liquid and rinsed on the upper surface by the cleaning liquid sprayed by the upper spray plate. When the filled products pass through the first bender and the second bender, they are bent and flipped 180 degrees to facilitate the dead-angle-free flushing of the circumferential side walls of the filled products. (2) Through the design of the first bender and the second bender, the filled products are continuously coiled between the first bender and the second bender, facilitating multiple turnovers for multiple flushes by the spray plate. Support bars are installed on the circumferential side walls of the first bender and the second bender to lift the inner diameter position of the bent position of the filled products, and spray holes are opened between the support bars to conduct reverse flushing from the lifted position inside the bent filled products, improving the flushing efficiency. (3) Through the design of the aggregator, when foam is generated in the cleaning liquid due to the continuous entry and exit of the filled products, it is intercepted and collected through the housing and the skirt. The air injection pipe is aligned with the outlet shell, and the gas blown over the filled products will entrain and gather the foam and lead it forward out of the main body. When the foam is gathered, the fins are also used to cooperate and converge to assist in defoaming, reducing the amount of foam and the pressure of foam extraction. Brief Description of the Drawings

Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] In the existing sausage raw material cleaning tank solution, the mentioned first-level tank and second-level tank are used to clean the raw materials in stages. During the process, the raw materials are not turned over, and the clear water is rinsed from top to bottom, and only acts on the upper surface of the raw materials. The lower surface cannot be directly rinsed. If the raw materials here are casings or filled products 6 after filling, it will cause residues on the lower surfaces of the casings or filled products 6. Moreover, because the filling of the meat sausage has a large oil content, when rinsed with clear water, the required cleaning degree is not achieved, and the required amount of clear water and rinsing time will increase significantly, resulting in the need to extend the length of the spray water tank for the equipment. At this time, in order to recycle the waste water, a separate oil-water separation device is required, and the floor areas of the main equipment and auxiliary equipment are relatively large, resulting in crowded factory building space.

[0029] As Figures 1-9 shown, this embodiment provides an automatic spray cleaning device for surface residual stuffing after meat product filling. To overcome the actual problems in the existing equipment that the cleaning efficiency of clear water for oil is low and the lower surface of the cylindrical filled product 6 cannot be directly rinsed by one-way spraying on the top surface, a specific configuration is provided: Regarding the soaking tank 3, referring to Figure 2 , the soaking tank 3 includes a main body 31 with an upward opening. The main body 31 is internally provided with a cleaning liquid, and the cleaning liquid is an alkaline cleaning liquid, which can emulsify the oil in the stuffing to reduce the oil viscosity and is more likely to peel off from the surface of the filled product 6. The oil removal effect is better than that of rinsing with clear water. At the same time, referring to Figure 3 and Figure 5, a first carrying roller 33 is provided in the middle of the main body 31. The first carrying roller 33 is located at a position close to the bottom surface in the lower part of the main body 31. The second carrying roller 34 is lower than the liquid level 7 of the cleaning liquid, so that the filled product 6 is suspended in the main body 31 and can be completely immersed in the cleaning liquid, enabling the filled product 6 to be fully soaked by the cleaning liquid. The solid fillings and oils on the surface are more likely to be emulsified and fall off. At the same time, second carrying rollers 34 are provided on both sides of the first carrying roller 33 of the main body 31. The first carrying roller 33 is higher than the liquid level 7 of the cleaning liquid, and can lift the filled product 6 out of the surface of the cleaning liquid, allowing the filled product 6 to repeatedly enter and exit the cleaning liquid. By repeatedly flushing the surface of the filled product 6 with the cleaning liquid, the cleaning efficiency is improved; Regarding the sprayer 4, refer to Figure 3 , the sprayer 4 includes a first bender 43 and a second bender 45. The first bender 43 and the second bender 45 are located at the edge positions on the left and right sides of the main body 31 and extend horizontally forward and backward. The filled product 6 enters from the upper right front of the main body 31 and reciprocally coils between the first bender 43 and the second bender 45 from front to back and from right to left. The first bender 43 and the second bender 45 are located on both sides of the first carrying roller 33, which can make the filled product 6 be lifted out and inserted back into the cleaning liquid more times, improving the cleaning efficiency. Moreover, a spray plate 42 is respectively provided directly above the first bender 43 and the second bender 45. The spray plate 42 generates a vertically downward water flow, which can flush the upper surface of the filled product 6 from top to bottom after lifting the filled product 6 out of the cleaning liquid. More importantly, refer to Figure 5 , whenever the filled product 6 flips around the first bender 43 and the second bender 45, the upper and lower surfaces of the filled product 6 will be flipped. In this way, the circumferential side walls of the entire filled product 6 can be alternately rinsed through the spray plate 42 located above, ensuring that the circumferential side walls of the filled product 6 can be flushed without dead angles. It should be noted that the sprayer 4 further includes a waste discharger 44. The waste discharger 44 is installed at the bottom of the front side of the main body 31 and can discharge the washed-down solid fillings and emulsified fat blocks from the front, so as to supplement new cleaning liquid and ensure the stability of the liquid level 7. It can also discharge solid debris to ensure the cleanliness of the cleaning liquid; Regarding the air spray pipe 8, the air spray pipe 8 is externally connected to a gas source, such as connecting an air blower. Refer to Figure 5 , the air spray pipe 8 is at the same height as the first carrying roller 33, that is, the air spray pipe 8 is located below the filled product 6 but above the liquid level 7 of the cleaning liquid. Among them, the air spray pipe 8 generates a vertically upward air flow, which can blow off the stubborn solid debris adhering to the surface of the filled product 6, further improving the cleaning efficiency of the stubborn solid debris.

[0030] The working principle of this embodiment is as follows: The continuous filling products 6 enter the main body 31 from left to right. The worker bends downward through the bending device 1 43 and inserts it into the cleaning liquid. The bearing roller 2 34 rolls the filling products 6 in the air to prevent the surface of the filling products 6 from being damaged by sliding friction of foreign objects. The filling products 6 are completely immersed in the cleaning liquid to soak and rinse the solid debris on the surface, and the grease is emulsified during the soaking. When the filled product 6 comes to the left side of the main body 31, the worker needs to do preliminary preparation work before entering the later automatic cleaning. Specifically, the filled product 6 passes through the position of the second bender 45 from bottom to top, and is bent to the right to pass through the second bender 45 and inserted into the cleaning liquid again. The filled product 6 is turned upside down and extended to the right until it passes through the first bender 43 from bottom to top again, and then it can be bent to the left to pass through the first bender 43 and inserted into the cleaning liquid again. Through reciprocating winding, until it leaves the main body 31 from the left side, the filled product 6 is turned over many times in the main body 31, and the cleaning liquid is inserted and taken out many times. With the spray plate 42 fixed above, the new cleaning liquid can be continuously sprayed from top to bottom to wash the circumferential side wall of the filled product 6 without dead angles, thereby improving the cleaning efficiency. When the filled product 6 passes through the position of the bearing roller 33, it is taken out of the cleaning liquid and inserted back again, so that the cleaning liquid can wash the outer surface of the filled product 6 multiple times, and at the position of the bearing roller 33, the airflow generated by the jet pipe 8 blows upward the solid debris on the outer surface of the filled product 6, and the stubbornly adhered solid debris is peeled off, and the washed solid debris can be discharged from the front side of the waste discharger 44 together with the old cleaning liquid, and the waste discharge position is at the front side, which will make the old cleaning liquid behind the main body 31 flow forward, so that the new cleaning liquid is added to the rear of the main body 31, and the filled product 6 enters the main body 31 from the front and leaves the main body from the rear. 31. When the filled product 6 just enters the cleaning liquid, there will definitely be the most solid debris on the surface. At this time, discharging waste from the front can make the path of most solid debris carried by the cleaning liquid shorter, and can be discharged from the main body 31 more smoothly, avoiding the accumulation of solid debris in the main body 31. When the filled product 6 leaves the cleaning liquid, it is flushed by the new cleaning liquid, which can ensure the cleanliness of the surface of the filled product 6 and prevent the outer surface of the filled product 6 after cleaning from being contaminated by the old cleaning liquid and solid debris for the second time. The circulation direction of the cleaning liquid and the moving direction of the filled product 6 can be optimized, so as to achieve more efficient surface cleaning of the filled product 6 and circulation replacement of the cleaning liquid.

[0031] In a further embodiment, to ensure the cleanliness of the cleaning fluid, refer to Figure 3 The bearing roller 34 is spaced a certain distance from the bottom of the main body 31 so that the filled product 6 is suspended and immersed in the cleaning liquid, and the waste discharger 44 is fixed at the lowest point of the main body 31. Figure 8, the waste discharger 44 is a tubular object horizontally arranged in front of the main body 31. The left end of the waste discharger 44 is provided with an outlet. A rectangular opening is provided at the lower part of the front side wall of the main body 31. The waste discharger 44 is installed through the rectangular opening of the front side wall of the main body 31. Moreover, the side of the waste discharger 44 facing the main body 31 is designed with an open end, which is communicated with the internal space of the main body 31, so as to facilitate the cleaning liquid in the main body 31 to carry solid debris and discharge from the left end outlet of the waste discharger 44 out of the main body 31. Therefore, the waste discharger 44 is arranged lower than the second carrying roller 34 to collect the solid residues sinking to the bottom; Meanwhile, referring to Figure 3 , Figure 5 and Figure 8 , a flusher 46 is installed at the rear side of the main body 31. The flusher 46 is a tubular object horizontally arranged at the rear side of the main body 31. The left end of the flusher 46 is externally connected to a pump to provide continuous cleaning liquid for the flusher 46. A plurality of water outlet nozzles are arranged along the axial direction of the flusher 46. An installation opening is formed at the lower part of the rear side wall of the main body 31. These water outlet nozzles extend through the installation opening into the main body 31. Moreover, the water outlet direction of the water outlet nozzles faces the direction of the waste discharger 44, that is, the flusher 46 serves as a supplementary point for the new cleaning liquid and can spray the cleaning liquid from the rear to the front. While continuously supplementing the new cleaning liquid for the main body 31, the old cleaning liquid and solid debris at the lower part of the rear side of the main body 31 are pushed more quickly towards the direction of the waste discharger 44. Cooperating with the filling product 6 coiled back and forth from the front to the rear, the discharge position of the old cleaning liquid is close to the newly entered filling product 6, and the new cleaning liquid is located at the position where the filling product 6 moves out of the main body 31, making full use of the flow of the cleaning liquid and ensuring the cleanliness of the filling product 6. The flusher 46 is communicated with the spray plate 42 through the delivery pipe 41.

[0032] In a further embodiment, the specific configurations of the second bender 45 and the first bender 43 are disclosed. The second bender 45 and the first bender 43 have the same structure. Referring to Figure 4, the bender II 45 and the bender I 43 can adopt a idler wheel structure, only the bearing is installed on the main body 31 and rotates passively as the filling product 6 moves. The bender I 43 includes two parallel middle tubes 431. The middle tubes 431 are hollow structures with openings facing backward. And a rotary connector is installed at the rear end of the middle tube 431. The conveying pipe 41 is connected to the middle tube 431 through a connector 47. The connector 47 adopts a four-way pipe. The flusher 46 and the spray plate 42 are connected to the middle tube 431 through the rotary connector to complete the dispersion and distribution of the new cleaning liquid. Among them, equidistantly arranged spray holes 433 are opened on the circumferential outer wall of the middle tube 431. The new cleaning liquid is sprayed from the position of the spray holes 433. When the filling product 6 bends and changes direction, the cleaning liquid can be sprayed from the central position outside the bend of the filling product 6 to the surrounding, flushing and cleaning the filling product 6 from more angles. And, annularly arrayed ribs 434 are arranged on the circumferential outer wall of the middle tube 431 along the axis of the middle tube 431. The ribs 434 and the spray holes 433 are arranged in a staggered manner. On the premise of not affecting the water discharge of the spray holes 433, the ribs 434 are used to lift the inner diameter position of the bent position of the filling product 6, reducing the surface area size of the filling product 6 being blocked during flushing, and further reducing the influence of the blockage on cleaning; It should be emphasized that the bender II 45 and the bender I 43 are actively rotated and driven by motors installed at the ends, providing auxiliary rotational driving force along the advancing direction of the filling product 6. Compared with only applying an external force to pull at the left end of the filling product 6, this multi-point synchronous pushing method can reduce the advancing resistance of the filling product 6. Only a servo motor needs to be used as the power source. The rotation speed of the servo motor is controllable, and the combined use of multiple servo motors can also ensure the consistency of the pushing rate. In this way, the filling product 6 can be relaxed and drooped into the cleaning liquid when advancing, avoiding the filling product 6 being tightened between the bender II 45 and the bender I 43 and unable to contact the cleaning liquid below; It should be noted that since the cleaning liquid in the conveying pipe 41 is provided by the flusher 46, the water spray head of the flusher 46 itself will spray the cleaning liquid outward. And, the position of the middle tube 431 is higher than the position of the flusher 46. Therefore, to ensure that the cleaning liquid can reach the position of the middle tube 431 smoothly, the pumping device connected to the flusher 46 needs to be a high-pressure water pump to ensure that the water pressure at the position of the middle tube 431 can meet the equipment requirements, so that the cleaning liquid can be smoothly sprayed from the position of the spray holes 433 of the middle tube 431.

[0033] In a further embodiment, referring to Figure 3 and Figure 4, since the filling product 6 needs to be repeatedly coiled multiple times to make full use of the length of the middle tube 431, and there is a risk of damage due to the mutual friction of the casings of the filling product 6, a relatively large distance needs to be opened when coiling outside the middle tube 431 to prevent the filling products 6 on the same middle tube 431 from rubbing against each other. This results in a smaller total number of coiling times and fewer filling products 6 that can be simultaneously cleaned in the main body 31, leading to a lower working efficiency of the cleaning equipment. At this time, blocking discs 432 are arranged at equal intervals along the axis of the middle tube 431. The blocking discs 432 play a limiting role in separating the adjacent front and rear filling products 6. In this way, even if the distance between the filling products 6 during coiling is small, there will be the blocking discs 432 for separation, and the adjacent filling products 6 will not directly contact each other. Thus, without increasing the length of the middle tube 431, more filling products 6 can be accommodated in the main body 31 for simultaneous cleaning, and the filling products 6 can also be prevented from being entangled with each other. At the same time, the radial line of the blocking disc 432 is perpendicular to the axis of the middle tube 431, and the circumferential side walls of two adjacent blocking discs 432 are in contact with each other, reducing the possibility of the filling product 6 entering between the two adjacent left and right blocking discs 432, preventing the filling product 6 from being squeezed by the two adjacent left and right blocking discs 432 and also avoiding the filling product 6 from being stuck.

[0034] In a further embodiment, referring to Figure 5 , there are two first carrying rollers 33, and the air spraying pipe 8 is arranged between the two first carrying rollers 33, and the top surface of the air spraying pipe 8 is lower than the top surface heights of the two first carrying rollers 33. This design can prevent the non-rotatable air spraying pipe 8 from wearing the casing of the filling product 6 when the filling product 6 passes above the air spraying pipe 8. Moreover, the air spraying pipe 8 is located above the liquid level 7 of the cleaning liquid, preventing the cleaning liquid from blocking the upward sprayed air flow and ensuring that the filling product 6 can be washed by a relatively high-speed air flow, improving the cleaning ability for stubborn solid debris.

[0035] In a further embodiment, when the filling product 6 is frequently inserted into and taken out of the cleaning liquid, a large amount of foam will be generated at the position of the liquid level 7 of the cleaning liquid. At this time, referring to Figure 6, the main body 31 is located just above the jet pipe 8 and a collector 9 is installed. The collector 9 adopts a hollow structure, and the opening of the collector 9 is downward and the opening position is higher than the liquid level 7 of the cleaning liquid. With this design, when the filling product 6 passes through the jet pipe 8, the foam on the surface of the filling product 6 and the emulsified oil will be blown upward, so that the surface attachments of the filling product 6 are partially peeled off, and the stubborn and inner attachments can be in direct contact with the cleaning liquid to complete a more thorough cleaning. At the same time, an outlet shell 93 is provided at the front end of the collector 9. The foam generated in the cleaning liquid will be blown into the collector 9 by the upward airflow, and most of the gas ejected from the jet pipe 8 is captured by the collector 9, so that an airflow flowing to the outlet shell 93 is generated inside the collector 9, which facilitates the concentrated discharge of the foam from the outlet shell 93 to prevent the foam from accumulating on the surface of the cleaning liquid. In this way, when the filling product 6 is subsequently separated from the cleaning liquid of the main body 31, too much foam will not adhere to the surface, thereby ensuring the cleaning effect of the filling product 6.

[0036] In a further embodiment, a specific configuration of the aggregator 9 is disclosed, referring to Figure 7 The collector 9 includes a hollow cover shell 91 which is narrow at the top and wide at the bottom. The cover shell 91 is in the shape of a trapezoid which is narrow at the top and wide at the bottom. As the height increases, the internal space gradually decreases. In addition, a fin 94 is fixedly mounted on the inner wall of the cover shell 91. The free end of the fin 94 extends upward at an angle to the middle of the cover shell 91. As the foam accumulates in the cover shell 91, the fin 94 can increase the surface area inside the cover shell 91, and contact with more foam to destroy its surface tension and cause the foam to burst. In addition, the upward movement will impact the fin 94 and will be squeezed and gathered toward the middle, so that the air pressure in the upper part of the cover shell 91 increases. At the same time, the foam is squeezed and gathered toward the middle, so that the foam is easier to break due to the increase in flow rate and external pressure. The outlet shell 93 is connected to the internal space of the cover shell 91, and the unbroken foam in the cover shell 91 can be discharged from the outlet shell 93 to the outside.

[0037] In a further embodiment, referring to Figure 7 and Figure 8, a skirt 92 is installed at the position of the bottom edge of the housing 91. The free end of the skirt 92 extends horizontally. The position of the skirt 92 is relatively high, leaving a sufficient distance from the top of the first carrier roller 33. The lowest point of the skirt 92 is higher than the filling product 6 above the first carrier roller 33. That is, this distance is greater than the outer diameter of the filling product 6, which does not affect the advancement of the filling product 6. Moreover, it can block and collect the foam generated by the filling product 6 entering and exiting the cleaning liquid. Specifically, when the filling product 6 is lifted out of the cleaning liquid from left to right, it will drive the foam at the liquid level 7 position of the left cleaning liquid to the right, contact the left skirt 92, and be guided by the skirt 92 to enter the middle housing 91 along the lower surface of the left skirt 92 and be gathered. When the filling product 6 is lifted out of the cleaning liquid from right to left, it will drive the foam at the liquid level 7 position of the right cleaning liquid to the right, contact the right skirt 92, and be guided by the skirt 92 to enter the middle housing 91 along the lower surface of the right skirt 92 and be gathered for centralized discharge. The design of the skirt 92 can capture the foam on the surface of the cleaning liquid in a large range on both sides of the first carrier roller 33, making most of the foam concentrate at the position of the housing 91. In this way, when the filling product 6 leaves the main body 31 from the second bender 45 on the left, there is less foam that can adhere to its surface, further reducing the possibility of secondary contamination of the filled product 6 after cleaning. Moreover, the skirt 92 guides the vast majority of the foam into the housing 91, which can facilitate the subsequent defoaming operation of the housing 91 and improve the defoaming efficiency.

[0038] In a further embodiment, referring to Figure 1 and Figure 2 , a top cover 32 is installed at the opening position at the top of the main body 31. The top cover 32 completely covers the opening position at the top of the main body 31. The top cover 32 shields and protects the main body 31 to prevent sundries from falling into the main body 31 and contaminating the cleaning liquid, and can also prevent the filling product 6 from being damaged by contact with sharp objects in the outside world. Among them, the spray plate 42 is fixedly penetrated on the top cover 32. A space is left between the top surface of the top cover 32 and the filling product 6 below to provide an installation position for the spray plate 42, so that the spray plate 42 can be suspended directly above the bending position of the filling product 6. The overall height of the top cover 32 or the installation height of the spray plate 42 can be adjusted to perform flushing and cleaning close to the filling product 6 to ensure the flushing efficiency. Side openings for the filling product 6 to pass through are provided on both sides of the top cover 32. The side opening on the right is located at the front, and the side opening on the left is located at the rear. In this way, when the filling product 6 moves from right to left and from front to back, the side openings enable the top cover 32 not to affect the entry and exit of the filling product 6 from the main body 31.

[0039] In a further embodiment, to connect this spraying system to an existing meat sausage filling system, referring to Figure 1, an extruder 1 and a knotter 2 are provided at the side opening on the right side of the top cover 32. The extruder 1 is located at the front side, the outlet of the extruder 1 is at the left end and is sleeved with sausage casings. The extruder 1 is filled with meat product stuffing, and the stuffing is filled into the sausage casings to form a continuous filling product 6. The filling product 6 continuously extends to the left as it expands during filling. The knotter 2 is located directly to the left of the extruder 1. When passing through the position of the knotter 2, a metal ring is installed for knotting to obtain a continuous filling product 6 with independent internal stuffing, so as to facilitate subsequent spray cleaning. As the continuous filling product 6 continuously moves to the left, it can enter the main body 31. At the same time, an output rack 5 is provided at the side opening on the left side of the top cover 32. There is a horizontal roller at the top of the output rack 5 for overhead conveying of the cleaned filling product 6, so as to control water while conveying. An annular clean water flusher can also be set at the position of the output rack 5, so that the filling product 6 passes through the annular clean water flusher, and the cleaning liquid or other residues on the surface of the filling product 6 are washed off, which can compensate for the incomplete cleaning caused by the unstable operation of the spray equipment and ensure the cleaning quality of the filling product 6.

[0040] The above is only a preferred embodiment of the present invention and is not used to limit the protection scope of the present invention.
