Description

Technical Field

[0001] The invention belongs to the technical field of sausage making equipment, and in particular relates to an automatic spray cleaning device for residual stuffing on the surface of a meat product after filling. Background Art

[0002] Sausage making involves crushing the meat, mixing it with auxiliary materials such as blanks, fillers, spices, etc., and injecting it into casings through a filling machine to obtain sausages. During the filling process, the filling will adhere to the surface of the filled product and need to be cleaned to ensure the cleanliness of the finished product and convenient storage.

[0003] The existing Chinese utility model patent with publication number CN217065235U discloses a sausage raw material cleaning pool, which performs graded cleaning on the raw materials through adjacently designed primary and secondary pools, and can also recycle wastewater. However, in actual use, because the filling of the sausage has a high oil content, clean water is flushed from top to bottom and only acts on the upper surface of the raw material, and the lower surface cannot be directly flushed. In addition, the clean water has a poor cleaning effect on grease, 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 area. In view of this, an automatic spray cleaning device for residual filling on the surface of meat products after filling is provided. Summary of the Invention

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

[0005] The technical solutions adopted to solve the above technical problems are:

[0006] An automatic spray cleaning device for residual fillings on the surface of meat products after filling, comprising:

[0007] The immersion tank includes a main body with an upward opening, the main body contains a cleaning liquid, a first carrier roller is provided in the middle of the main body, and second carrier rollers are provided on both sides of the first carrier roller, the second carrier roller is lower than the liquid level of the cleaning liquid, and the first carrier roller is higher than the liquid level of the cleaning liquid;

[0008] A sprayer, comprising a first bender and a second bender, wherein the filled product is reciprocated and coiled from front to back between the first bender and the second bender, the first bender and the second bender being located on either side of the first carrier roller. A spray plate is provided directly above each bender, the spray plate generating a vertical downward water flow. The sprayer also comprises a waste drainer, which is mounted on the front bottom of the main body;

[0009] The air jet pipe is located at a height equal to that of the supporting roller and generates a vertical upward air flow.

[0010] Furthermore, the waste discharger is arranged below the second carrying roller, and equidistantly arranged scrubbers are installed on the rear side of the main body. The scrubbers are arranged vertically forward and are connected to the spray plate through a conveying pipe.

[0011] Through the above technical solution, in order to ensure the cleanliness of the cleaning liquid, the flusher continuously replenishes new cleaning liquid for the main body from back to front, and the old cleaning liquid is discharged by the waste discharger on the front side of the main body, and cooperates with the filling products that reciprocate from front to back. The discharge position of the old cleaning liquid is close to the newly entered filling products, and the new cleaning liquid is located at the position where the filling products move out of the main body, making full use of the cleaning liquid and ensuring the cleanliness of the filling products.

[0012] Furthermore, the bender 1 includes two parallel middle tubes, the delivery pipe is connected to the middle tube through a communicating tube, the circumferential outer wall of the middle tube is provided with a ring array of branches along the axis of the middle tube, the circumferential outer wall of the middle tube is provided with equidistantly arranged nozzles, the branches and nozzles are staggered, and the structure of the bender 2 is the same as that of the bender 1.

[0013] Through the above technical solution, the filled product is bent at one position of the bender, the inner diameter position of the bent position of the filled product is suspended by the support bar, and cleaning liquid is sprayed from the spray hole position, avoiding the impact of obstruction on the cleaning efficiency when the filled product bends and changes direction.

[0014] Furthermore, the middle tube is provided with baffles equidistantly arranged along the axis of the middle tube, the diameters of the baffles are perpendicular to the axis of the middle tube, and the circumferential side walls of two adjacent baffles are in contact with each other.

[0015] Through the above technical solution, the baffle plate separates and limits the filling products in the front and back directions, fully utilizing the length of the middle tube so that the filling products can be wound back and forth as much as possible, and can also prevent the filling products from being entangled with each other.

[0016] Furthermore, two carrying rollers are provided, and the air injection pipe is provided between the two carrying rollers, and the air injection pipe is located above the liquid level of the cleaning liquid.

[0017] With the above technical solution, the filled product passes over the air jet tube, which is clamped between two supporting rollers, to prevent the air jet tube, which cannot rotate, from abrading the casing of the filled product.

[0018] Furthermore, a collector is installed on the main body directly above the air injection pipe, the collector opens downward and the opening position is higher than the liquid level of the cleaning fluid, and an outlet shell is provided at the front end of the collector.

[0019] Through the above technical solution, the foam generated in the cleaning liquid will blow off the foam and emulsified oil on the surface of the filled product when the filled product passes through the air jet pipe, and come into contact with the cleaning liquid to complete a more thorough cleaning. The foam is blown into the accumulator, which is convenient for centralized discharge out of the shell, preventing foam accumulation from affecting the subsequent cleaning of the surface of the filled product separated from the main body.

[0020] Furthermore, the collector includes a hollow cover shell that is narrow at the top and wide at the bottom. Fins are fixedly mounted on the inner wall of the cover shell. The free ends of the fins extend obliquely upward to the middle of the cover shell. The lead-out shell is in communication with the inner space of the cover shell.

[0021] Through the above technical solution, the cover adopts a trapezoidal shape that is narrow at the top and wide at the bottom. As the foam accumulates in the cover, the fins increase the surface area inside the cover and squeeze the foam toward the middle, making the foam easier to break.

[0022] Furthermore, a skirt is installed at the bottom edge of the cover shell, the free end of the skirt extends horizontally, and the lowest point of the skirt is higher than the filling product above the supporting roller.

[0023] Through the above technical solution, the skirt is positioned higher and does not affect the advancement of the filled products. It can also block and collect the foam generated by the filled products entering and exiting the cleaning liquid. The skirt guides the foam into the cover for subsequent defoaming operations, thereby improving the defoaming efficiency.

[0024] Furthermore, a top cover is installed at the top opening of the main body, the spray plate is fixed on the top cover, and side openings are opened on both sides of the top cover for the filling products to pass through.

[0025] Through the above technical solution, the top cover shields and protects the main body to prevent debris from falling in, and provides an installation position for the spray plate, so that the spray plate can be suspended and erected directly above the bending position of the filling product to ensure the efficiency of flushing, and the side port does not affect the filling product from entering and exiting the main body.

[0026] Furthermore, the side opening on the right side of the top cover is provided with an extruder and a knotter, and the side opening on the left side of the top cover is provided with an output rack.

[0027] Through the above technical solution, the extruder is filled with meat product filling, and then filled into the casing to form a continuous filled product. When passing through the knotter position, a metal ring is installed for knotting to obtain a continuous but independent filled product with internal fillings, so as to facilitate subsequent spray cleaning. The output rack is used for overhead transmission of the cleaned filled product so that water can be controlled while being transported.

[0028] The beneficial effects of the present invention are as follows:

[0029] (1) The present invention is provided with a soaking tank, a sprayer and an air jet pipe. After filling, the continuously filled products are introduced into the cleaning liquid of the soaking tank. The air jet pipe flushes away the emulsions and attachments on the surface of the filled products after the filled products are separated from the cleaning liquid. As the benders 1 and 2 rotate, the filled products are lifted out of the cleaning liquid and the cleaning liquid sprayed from the spray plate above is used to wash the upper surface. When the filled products pass through the benders 1 and 2, they are bent and turned 180 degrees, so that the circumferential side wall of the filled products can be flushed without dead angles.

[0030] (2) The present invention adopts the design of the first and second benders, so that the filled product is continuously coiled between the first and second benders, and is turned over multiple times to facilitate multiple flushing by the spray plate. Support bars are installed on the circumferential side walls of the first and second benders, so that the inner diameter position of the bent position of the filled product is suspended, and spray holes are opened between the support bars. Reverse flushing is performed from the suspended position inside the bent filled product, thereby improving the flushing efficiency.

[0031] (3) The present invention adopts the design of the aggregator. When the cleaning liquid generates foam due to the continuous flow of the filling products, the foam is intercepted and collected by the cover and the skirt. The air jet is directly opposite to the outlet shell. The gas blown through the filling products will entrain and gather the foam and lead it forward out of the main body. When the foam is gathered, the fins are used to cooperate and converge to assist in defoaming, thereby reducing the amount of foam and lowering the pressure of foam discharge.

[0042] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, 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 intended to limit the present invention.

[0043] The existing sausage raw material cleaning pool solution, the mentioned primary pool and secondary pool, performs graded cleaning on the raw materials. During the process, the raw materials will not be turned over, but will be rinsed with clean water from top to bottom, and only on the upper surface of the raw materials, and the lower surface cannot be directly rinsed. If the raw materials here are casings or filled products 6 after filling, there will still be residues on the lower surface of the casings or filled products 6. Moreover, because the fillings of meat sausages contain a large amount of oil, rinsing with clean water cannot achieve the required level of cleanliness. The required amount of clean 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, the wastewater must also be recycled, which requires separate oil-water separation equipment. The main equipment and auxiliary equipment occupy a large area, resulting in crowded factory space.

[0044] like Figures 1-9 As shown, this embodiment provides an automatic spray cleaning device for residual fillings on the surface of meat products after filling. To overcome the practical problems of low efficiency of clean water in cleaning grease in existing equipment and the inability to directly rinse the lower surface of the cylindrical filled product 6 due to the one-way spraying on the top surface, a specific configuration is provided:

[0045] For soaking pool 3, see Figure 2 The soaking tank 3 includes a main body 31 with an upward opening. The main body 31 has a built-in cleaning liquid. The cleaning liquid is an alkaline cleaning liquid, which can emulsify the grease in the filling to reduce the viscosity of the grease, making it easier to peel off from the surface of the filling 6. Compared with clear water rinsing, the degreasing effect is better. At the same time, referring to Figure 3 and Figure 5A carrying roller 1 33 is provided in the middle of the main body 31. The carrying roller 1 33 is located at the lower part of the main body 31 close to the bottom surface. The carrying roller 2 34 is lower than the liquid level 7 of the cleaning liquid, so that the filling product 6 is suspended in the main body 31 and can be completely immersed in the cleaning liquid, so that the filling product 6 is fully soaked in the cleaning liquid, and the solid fillings and grease on the surface are more easily emulsified and dropped. At the same time, the main body 31 is provided with a carrying roller 2 34 on both sides of the carrying roller 1 33. The carrying roller 1 33 is higher than the liquid level 7 of the cleaning liquid, which can lift the filling product 6 out of the cleaning liquid surface, so that the filling product 6 can repeatedly enter and exit the cleaning liquid, and the surface of the filling product 6 is repeatedly flushed by the cleaning liquid, thereby improving the cleaning efficiency.

[0046] For the sprinkler 4, refer to Figure 3 The sprayer 4 includes a bender 1 43 and a bender 2 45. The bender 1 43 and the bender 2 45 are located at the left and right edges of the main body 31 and extend horizontally front to back. The filling product 6 enters from the right front of the main body 31 and winds back and forth between the bender 1 43 and the bender 2 45 from front to back and from right to left. The bender 1 43 and the bender 2 45 are located on both sides of the carrier roller 1 33, so that the filling product 6 can be taken out and inserted back into the cleaning liquid more times, thereby improving the cleaning efficiency. In addition, a spray plate 42 is respectively provided above the bender 1 43 and the bender 2 45. The spray plate 42 generates a vertical downward water flow, which can flush the upper surface of the filling product 6 from top to bottom after the filling product 6 is taken out of the cleaning liquid. More importantly, referring to Figure 5 Whenever the filled product 6 turns around the first bender 43 and the second bender 45, the upper and lower surfaces of the filled product 6 will be turned over. In this way, the spray plate 42 located above can alternately rinse the entire circumferential side wall of the filled product 6, ensuring that the circumferential side wall of the filled product 6 can be rinsed without any dead angle. It should be noted that the sprayer 4 also includes a waste drainer 44. The waste drainer 44 is installed at the front bottom of the main body 31. It can discharge the flushed solid fillings and emulsified fat blocks from the front to replenish new cleaning liquid to ensure the stability of the liquid level 7. It can also discharge solid debris to ensure the cleanliness of the cleaning liquid.

[0047] Regarding the jet pipe 8, the jet pipe 8 is connected to an external air source, such as an air pump, see Figure 5 The air jet pipe 8 is located at the same height as the supporting roller 33, that is, the air jet pipe 8 is located below the filled product 6 but above the liquid level 7 of the cleaning liquid. The air jet pipe 8 generates a vertical upward airflow, 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.

[0048] The working principle of this embodiment is as follows:

[0049] Continuously, the filled products 6 enter the main body 31 from left to right. The worker bends the products downwards through the first bender 43 and inserts them into the cleaning liquid. The second carrier roller 34 rolls the filled products 6 overhead to prevent the surface of the filled products 6 from being damaged by sliding friction from foreign objects. The filled 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 process.

[0050] When the filled product 6 reaches the left side of the main body 31, workers need to perform preliminary preparations before entering the subsequent automatic cleaning process. Specifically, the filled product 6 is passed from bottom to top through the position of the second bender 45, bent to the right, passed through the second bender 45, and then 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. It can then bend to the left, passed 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, the filled product 6 is turned over many times in the main body 31 and the cleaning liquid is inserted and removed many times. With the spray plate 42 fixed above, the new cleaning liquid can be continuously sprayed from top to bottom to clean the circumferential side wall of the filled product 6 without any dead angle, thereby improving the cleaning efficiency.

[0051] When the filled product 6 passes through the position of the carrier roller 33, it is taken out of the cleaning liquid and inserted back again, so that the cleaning liquid can flush the outer surface of the filled product 6 multiple times. At the position of the carrier roller 33, the air flow generated by the air jet 8 blows upward the solid debris on the outer surface of the filled product 6, peeling off the stubbornly adhered solid debris. The washed solid debris can be discharged together with the old cleaning liquid from the waste discharger 44 on the front side. The waste discharge position is at the front side, which will make the old cleaning liquid at the rear of the main body 31 flow forward, so that the new cleaning liquid is replenished to the rear of the main body 31. 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 more smoothly from the main body 31, avoiding the accumulation of solid debris in the main body 31. When the filled product 6 leaves the cleaning liquid, it is flushed by 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. By optimizing the circulation flow direction of the cleaning liquid and the movement direction of the filled product 6, more efficient surface cleaning of the filled product 6 and circulation replacement of the cleaning liquid can be achieved.

[0052] In a further embodiment, to ensure the cleanliness of the cleaning fluid, refer to Figure 3 The second carrier roller 34 is spaced a certain distance from the bottom of the main body 31 so that the filled product 6 can be immersed in the cleaning liquid, and the waste discharger 44 is fixed at the lowest point of the main body 31. Figure 8The waste discharger 44 is a tubular object horizontally placed on the front side of the main body 31. An outlet is provided at the left end of the waste discharger 44. A rectangular opening is provided at the lower portion 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. In addition, the waste discharger 44 is open on the side facing the main body 31 and is connected to the internal space of the main body 31 to facilitate the cleaning liquid in the main body 31 to be discharged from the main body 31 through the left end outlet of the waste discharger 44 together with the solid debris. Therefore, the waste discharger 44 is arranged below the second carrier roller 34 in order to collect the solid residues that sink to the bottom.

[0053] At the same time, refer to Figure 3 、 Figure 5 and Figure 8 , a flusher 46 is installed on the rear side of the main body 31. The flusher 46 is a tubular object placed horizontally on the rear side of the main body 31. The left end of the flusher 46 is connected to a pump to provide continuous cleaning liquid for the flusher 46. The flusher 46 has multiple water nozzles arranged axially. A mounting port is opened at the lower part of the rear side wall of the main body 31. These water nozzles extend through the mounting port to the interior of the main body 31, and the water outlet direction of the water nozzle is facing the direction of the waste discharger 44. That is, the flusher 46 serves as a replenishment point for new cleaning liquid, which can be used to clean the surface of the main body 31. The cleaning liquid is sprayed from back to front to continuously replenish the main body 31 with new cleaning liquid. At the same time, the old cleaning liquid and solid debris at the lower rear side of the main body 31 are pushed more quickly toward the waste discharger 44. In conjunction with the filling product 6 that winds back and forth from front to back, the old cleaning liquid is discharged 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 connected to the spray plate 42 through the delivery pipe 41.

[0054] In a further embodiment, a specific configuration of the second bender 45 and the first bender 43 is disclosed. The second bender 45 has the same structure as the first bender 43. Figure 4, the bender 2 45 and the bender 1 43 can adopt an idler structure, only making the bearing mounted on the main body 31, passively rotating with the movement of the filling product 6, the bender 1 43 includes two parallel middle tubes 431, the middle tube 431 is a hollow structure with an opening facing backward, and a rotary connector is installed at the rear end of the middle tube 431, the delivery pipe 41 is connected to the middle tube 431 through a connecting pipe 47, and the connecting pipe 47 adopts a four-way pipe, connecting the flusher 46 and the spray plate 42 to the middle tube 431 through a rotary connector to complete the dispersion and distribution of the new cleaning liquid, wherein the outer wall of the circumference of the middle tube 431 is provided with equidistantly arranged The spray hole 433 sprays new cleaning liquid from the position of the spray hole 433. When the filling product 6 bends and changes direction, the cleaning liquid can be sprayed from the center position of the bending outside the filling product 6 to the surrounding area, so as to flush and clean the filling product 6 from more angles. In addition, the outer wall of the circumference of the middle tube 431 is provided with a ring array of support bars 434 along the axis of the middle tube 431. The support bars 434 and the spray hole 433 are staggered. Under the premise of not affecting the water discharge of the spray hole 433, the support bars 434 are used to suspend the inner diameter position of the bending position of the filling product 6, thereby reducing the surface area of ​​the filling product 6 that is adjusted during flushing, and further reducing the impact of obstruction on cleaning;

[0055] It should be emphasized that motors are installed at the ends of the second bender 45 and the first bender 43 for active rotational drive, providing auxiliary rotational propulsion along the forward direction of the filled product 6. Compared with applying external force only at the left end of the filled product 6 to pull it, this multi-point synchronous propulsion method can reduce the forward resistance of the filled product 6. It only requires the use of a servo motor as the power source. The speed of the servo motor is controllable, and the combination of multiple servo motors can also ensure a consistent pushing rate. In this way, the filled product 6 can relax and sag into the cleaning liquid as it moves forward, avoiding the filled product 6 being tightened between the second bender 45 and the first bender 43 and unable to contact the cleaning liquid below.

[0056] It should be noted that, because the cleaning liquid of the delivery pipe 41 is provided by the flusher 46, the water outlet nozzle of the flusher 46 itself will spray the cleaning liquid outward, and the position of the middle pipe 431 is higher than the position of the flusher 46. Therefore, in order to ensure that the cleaning liquid can smoothly reach the position of the middle pipe 431, the pump connected to the flusher 46 must be a high-pressure water pump to ensure that the water pressure at the position of the middle pipe 431 can meet the equipment requirements, so that the cleaning liquid can be smoothly sprayed out at the spray hole 433 of the middle pipe 431.

[0057] In a further embodiment, referring to Figure 3 and Figure 4Because the filling product 6 needs to be coiled back and forth many times to make full use of the length of the middle tube 431, and because the casings of the filling product 6 rub against each other and there is a risk of damage, a larger distance needs to be opened when coiling on the outside of the middle tube 431 to prevent the filling products 6 on the same middle tube 431 from rubbing against each other, which results in a smaller total number of coiling times, and a smaller number of filling products 6 that can be cleaned in the main body 31 at the same time, resulting in a lower working efficiency of the cleaning equipment. At this time, the middle tube 431 is equidistantly arranged with baffles 432 along the axis of the middle tube 431. The baffles 432 play a limiting role in separating the front and rear adjacent filling products 6. Even if the spacing between the coiled filling products 6 is small, there will be baffles 432 to separate them, and adjacent filling products 6 will not directly contact each other. Therefore, more filling products 6 can be accommodated in the main body 31 for simultaneous cleaning without increasing the length of the middle tube 431, and the filling products 6 can be prevented from being entangled with each other. At the same time, the diameter of the baffle 432 is perpendicular to the axis of the middle tube 431, and the circumferential side walls of the two adjacent baffles 432 contact each other, reducing the possibility of the filling products 6 entering between the left and right adjacent baffles 432, preventing the filling products 6 from being squeezed by the left and right baffles 432, and also preventing the filling products 6 from being stuck.

[0058] In a further embodiment, referring to Figure 5 There are two supporting rollers 33, and the air jet pipe 8 is arranged between the two supporting rollers 33, and the top surface of the air jet pipe 8 is lower than the top surface height of the two supporting rollers 33. This design can prevent the non-rotating air jet pipe 8 from wearing the casing of the filled product 6 when the filled product 6 passes over the air jet pipe 8. In addition, the air jet pipe 8 is located above the liquid level 7 of the cleaning liquid to prevent the cleaning liquid from blocking the upward airflow, ensuring that the filled product 6 can be washed by a higher-speed airflow, thereby improving the cleaning ability of stubborn solid debris.

[0059] In a further embodiment, when the filling product 6 is frequently inserted and taken out of the cleaning liquid, more foam will be generated at the liquid level 7 of the cleaning liquid. Figure 6The main body 31 is provided with a collector 9 just above the jet pipe 8. The collector 9 adopts a hollow structure, and the collector 9 opens 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 come into direct contact with the cleaning liquid, completing 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, there will be no excessive foam adhering to the surface, thereby ensuring the cleaning effect of the filling product 6.

[0060] 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 that is narrow at the top and wide at the bottom. The cover shell 91 adopts a trapezoidal shape that is narrow at the top and wide at the bottom. The internal space gradually decreases as the height increases. In addition, fins 94 are fixedly installed on the inner wall of the cover shell 91. The free ends of the fins 94 extend obliquely upward to the middle of the cover shell 91. As the foam accumulates in the cover shell 91, the fins 94 can increase the surface area inside the cover shell 91, contact with more foam, destroy its surface tension and cause the foam to burst. In addition, the upward flow will impact the fins 94 and will be squeezed and converged toward the middle, so that the air pressure in the upper part of the cover shell 91 increases, and the foam is squeezed and converged toward the middle at the same time, making the foam 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.

[0061] In a further embodiment, referring to Figure 7 and Figure 8A skirt 92 is installed at the bottom edge of the cover 91. The free end of the skirt 92 extends horizontally. The skirt 92 is located higher and has a sufficient distance from the top of the carrying roller 33. The lowest point of the skirt 92 is higher than the filling product 6 above the carrying 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 raised from the left to the right into the cleaning liquid, the foam at the liquid level 7 of the left cleaning liquid will be driven to the right, contacting the left skirt 92, and guided by the skirt 92 to enter the middle cover 91 along the lower surface of the left skirt 92 and be gathered, while the filling product 6 is raised from the right to the left for cleaning. When the liquid is liquid, the foam at the liquid level 7 of the right cleaning liquid will be driven to the right, contact the right skirt 92, and be guided by the skirt 92 along the lower surface of the right skirt 92 into the middle cover 91 position to be gathered so as to be discharged centrally. The design of the skirt 92 can capture the foam on the surface of the cleaning liquid in a large range on the left and right sides of the supporting roller 33, so that most of the foam is concentrated at the cover 91 position. In this way, when the filling product 6 leaves the main body 31 from the left bender 2 45 position, there is less foam to adhere to the surface, further reducing the possibility of secondary contamination of the filling product 6 after cleaning. Moreover, the skirt 92 guides most of the foam into the cover 91, which can facilitate the subsequent defoaming operation of the cover 91 and improve the defoaming efficiency.

[0062] In a further embodiment, referring to Figure 1 and Figure 2 The top cover 32 is provided with a top cover 32 on the top opening of the main body 31, and the top cover 32 is completely provided at the top opening of the main body 31. The top cover 32 shields and protects the main body 31 to prevent debris from falling into the main body 31 and contaminating the cleaning liquid. It can also prevent the filling product 6 from being damaged by contact with sharp external objects. Among them, the spray plate 42 is fixed on the top cover 32, and a space is left between the top surface of the top cover 32 and the filling product 6 below, providing a mounting position for the spray plate 42, so that the spray plate 42 can be suspended and mounted just above the bending position of the filling product 6. The overall height of the top cover 32 or the mounting height of the spray plate 42 can be adjusted, and the flushing and cleaning can be performed near the filling product 6 to ensure the flushing efficiency. Side openings are provided on both sides of the top cover 32 for the filling product 6 to pass through. 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 or from front to back, the side openings prevent the top cover 32 from affecting the filling product 6 from entering and exiting the main body 31.

[0063] In a further embodiment, in order to connect the spray system to the existing meat sausage filling system, refer to Figure 1The side opening on the right side of the top cover 32 is provided with an extruder 1 and a knotter 2. The extruder 1 is located on the front side. The outlet of the extruder 1 is at the left end and is covered with a casing. The extruder 1 is filled with meat product stuffing and filled into the casing to form a continuous filling product 6. The filling product 6 continues to extend to the left as the filling expands. The knotter 2 is located on the left side of the extruder 1. When passing through the knotter 2 position, a metal ring is installed to tie a knot to obtain a continuous but independent filling product 6 for subsequent spray cleaning. As the continuous filling product 6 continues By moving left, one 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. A horizontal roller is provided on the top of the output rack 5 for overhead conveying of the cleaned filling products 6 so as to control water during conveyance. An annular clean water flusher can also be provided at the output rack 5 to allow the filling products 6 to pass through the annular clean water flusher and flush away the cleaning liquid or other residues on the surface of the filling products 6. This can compensate for incomplete cleaning caused by unstable operation of the spraying equipment and ensure the cleaning quality of the filling products 6.

[0064] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
