Description
Technical Field
[0001] This invention relates to the field of conveying device technology, specifically to an anti-drop conveying device for meatball production. Background Technology
[0002] In the frozen prepared food and meat product processing industry, meatballs (livestock and poultry meatballs, fish balls, vegetable balls, etc.) are the core mass-production product category. The core processes of their automated production lines are pulping, forming, cooking, cooling, quick freezing, and packaging. The material transfer between adjacent processes is highly dependent on continuous conveying devices.
[0003] Currently, the mainstream meatball production lines use food-grade belt conveyors and stainless steel mesh belt conveyors. Their core function is to continuously and stably transfer the meatballs output from the previous process to the next process. However, freshly formed raw meatballs have a high water content, smooth surface, soft texture, and are spherical. After cooking, the surface of the meatballs is oily and more lubricating. During the conveying process, problems such as rolling, bouncing, and jamming can easily occur. This not only causes material loss and increased production costs, but the fallen meatballs can also pollute the production environment, increase cleaning difficulty, and even cause equipment jamming.
[0004] To address the issue of meatballs falling off, existing technologies generally employ solutions such as adding flexible skirts or rigid side guards to both sides of the conveyor belt and setting anti-slip bumps or horizontal stripes on the surface of the conveyor belt. During the conveying process of meatballs, the grease and protein juice released from the meatballs will adhere to the surface of the conveyor belt and side guards, which is difficult to thoroughly clean with conventional cleaning methods. Long-term use can lead to the growth of microorganisms and pose a risk of food contamination. Summary of the Invention
[0005] This invention proposes an anti-drop conveyor device for meatball production, which solves the problem in the prior art where the juice extracted from meatballs remains on the conveyor belt and sidewalls, causing food contamination risks.
[0006] The technical solution of the present invention is as follows: A meatball production anti-drop conveying device includes a conveyor belt and baffles. Two baffles are provided, located on opposite sides of the top of the conveyor belt. The conveyor belt has multiple rows of conveying grooves for receiving meatballs. The device also includes: A conveyor box, wherein the conveyor belt is installed inside the conveyor box, and the conveyor box is connected to an inlet channel and an outlet channel; A limiting plate is disposed inside the conveyor box and above the conveyor belt to confine the meatballs inside the conveyor trough. The scraper is fixedly disposed on the outside of the conveyor belt. The scraper and the conveying groove are staggered. The scraper can separate the meatballs. At the same time, the scraper moves with the conveyor belt to scrape the surface of the limiting plate and the baffle. A cleaning pipe is disposed below the conveyor belt and has a nozzle for spraying cleaning liquid onto the conveyor belt and the surface of the scraper blade; A rinsing pipe is disposed below the conveyor belt and has nozzles for spraying clean water onto the conveyor belt and the surface of the scraper blades. A wiping shaft is rotatably disposed inside the conveyor box. The wiping shaft is located below the conveyor belt. An absorbent roller for wiping and absorbing liquid from the surface of the conveyor belt and the scraper is disposed outside the wiping shaft. The wiping shaft is provided in two sets. The cleaning tube, one set of the wiping shaft, the rinsing tube and the other set of the wiping shaft are arranged in sequence below the conveyor belt along the running direction of the conveyor belt. Each group has two wiping shafts, which work alternately. The conveyor box is equipped with a drying mechanism for drying the absorbent rollers. The drying mechanism includes: The drying cylinder is provided in two sets, with two drying cylinders in each set. The drying cylinders correspond one-to-one with the wiping shafts. The two drying cylinders are located on both sides of the conveyor box and are connected to the conveyor box. The wiping shafts are movably located inside the conveyor box. When one wiping shaft is located below the conveyor belt, the other wiping shaft is located inside the drying cylinder. A heating jacket is disposed outside the drying cylinder, and a heater is disposed inside the heating jacket. The drying cylinder is provided with an exhaust port for steam discharge. An opening and closing plate is movably disposed inside the conveying box and is used to open and close the drying cylinder when the wiping shaft enters and exits the drying cylinder; The conveying box includes a main body and a bottom trough. The bottom trough is fixedly installed at the bottom end of the main body by a telescopic sleeve. One end of the bottom trough is connected to a sewage discharge trough for collecting clean wastewater. The main body is equipped with telescopically adjustable support legs.
[0007] To keep the meatballs fresh during the transport process, a cold air box is also included, which is connected to the transport box through multiple cold air pipes.
[0008] To ensure that the meatballs enter the conveyor trough one by one, anti-fall plates and arranging plates are respectively provided on both sides of the bottom of the feeding channel along the direction of the conveyor belt. The anti-fall plates are used to prevent the meatballs from rolling backward. The bottom ends of the arranging plates and the limiting plates are flush. The arranging plates block the meatballs located on the surface of the conveyor belt and make the meatballs that fall into the conveyor trough move forward with the conveyor belt.
[0009] To enable the wiping shaft to move and rotate, one of the drying cylinders in each group is equipped with an electric cylinder, and a motor is fixedly installed at the output end of the electric cylinder. The wiping shaft is fixedly installed at the output end of the motor.
[0010] To replace the absorbent roller, a replacement sleeve is slidably mounted on the outside of the wiping shaft. The replacement sleeve is detachably connected to the wiping shaft by bolts, and the absorbent roller is fixedly mounted on the outside of the replacement sleeve.
[0011] To reduce the impact of cleaning fluid and water on meatball transport, a partition is fixedly installed inside the transport box. The partition is located in the middle between the upper and lower layers of the conveyor belt to separate the transport side and the idle side of the conveyor belt.
[0012] To prevent the cleaning solution and water from freezing, both the cleaning tube and the rinsing tube are connected to a liquid delivery tube, which is wrapped around the outside of the heating jacket.
[0013] The working principle and beneficial effects of this invention are as follows: 1. In this invention, a closed-loop anti-drop system is formed by a multi-limiting structure consisting of a conveying trough, a limiting plate, a baffle, an anti-drop plate, and an arranging plate. The conveying trough provides bottom containment and limitation for the meatballs, the limiting plate confines the meatballs within the conveying trough from above, the baffle provides side blocking, the anti-drop plate at the feeding end prevents the meatballs from rolling backward, and the arranging plate guides the meatballs to fall into the conveying trough in an orderly manner and prevents them from piling up and falling. At the same time, scrapers that are staggered with the conveying trough can separate the meatballs and prevent them from getting stuck and falling due to mutual squeezing. Compared with the single skirt or baffle anti-drop solution in the prior art, the anti-drop efficiency is greatly improved, and material loss and production costs are significantly reduced.
[0014] 2. This invention features a fully automated self-cleaning process consisting of scraping, spraying cleaning liquid, absorbing water and wiping, spraying clean water, and secondary absorbing water and wiping. The scraper moves with the conveyor belt and simultaneously scrapes away the adhering juices on the surfaces of the limiting plate and baffle. Then, the scraper and conveyor belt are cleaned, achieving full-area cleaning of the conveyor belt, scraper, limiting plate, and baffle without any dead corners. The wastewater after cleaning is collected through the bottom trough and discharged into the sewage trough to avoid juice residue. At the same time, the water absorption roller adopts an alternating working and drying design to ensure that the wiping function is continuously effective, solving the food contamination risk of residual grease and protein juice on the surface of the conveyor belt and baffle in the prior art, and the growth of microorganisms after long-term use.
[0015] 3. In this invention, the influence of liquid on meatball transportation during the cleaning process is solved by the partition. The problem of freezing of cleaning liquid and water in low-temperature environment is solved by the cooperation of liquid delivery pipe and heating sleeve. The expansion sleeve keeps one side of the sewage trough in a lower position, which can be flexibly adapted to the collection of cleaning sewage. The sewage trough realizes the rapid diversion of sewage.
[0016] 4. In this invention, a low-temperature preservation structure with a cold air box and cold air pipe is added to supply cold air into the conveying box, so that the conveying box maintains a low-temperature environment. This can effectively inhibit the growth of microorganisms in the meatballs during the conveying process, and at the same time slow down the deterioration of the raw meatballs. This solves the problem that existing meatball conveying devices lack preservation function and that long-distance conveying can easily lead to a decline in meatball quality.
[0017] 5. In this invention, the wiping shaft is moved by an electric cylinder and rotated by a motor, so that the two wiping shafts work alternately. When one wiping shaft performs water absorption and wiping, the other is dried in the drying cylinder. The water absorption roller can be dried without stopping the machine, ensuring the continuity of the cleaning process. In addition, the heating jacket not only provides a drying heat source for the drying cylinder, but also provides heat tracing for the liquid delivery pipe, realizing the reuse of the heat source.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0022] like Figures 1 to 9 As shown in the figure, this embodiment proposes a meatball production anti-drop conveying device, including a conveyor belt 1 and baffles 2. Two baffles 2 are provided, and the two baffles 2 are located on both sides of the top of the conveyor belt 1. Multiple rows of conveying grooves for accommodating meatballs are opened on the conveyor belt 1. It also includes a conveying box, a limiting plate 7, a scraper 10, a cleaning pipe 13, a rinsing pipe 14, and a wiping shaft 17.
[0023] The conveyor belt 1 is installed inside the conveyor box. Inside the conveyor box, a drive roller 3 and a driven roller 4 are rotatably mounted. The conveyor belt 1 is sleeved on the outside of the drive roller 3 and the driven roller 4. A drive motor 21 for driving the drive roller 3 to rotate is installed on the conveyor box. Baffles 2 are fixedly installed inside the conveyor box and symmetrically arranged on both sides of the top of the conveyor belt 1 to laterally block and limit the meatballs. The conveyor box is connected to an inlet channel 5 and an outlet channel 6. The inlet channel 5 is located at the top of the conveyor box and above the feeding position of the conveyor belt 1. The outlet channel 6 is located on the side of the conveyor box away from the inlet channel 5 and at the unloading position of the conveyor belt 1. The conveyor box includes a main body 101 and a bottom trough 102. The bottom trough 102 is fixedly installed at the bottom end of the main body 101 by a telescopic sleeve. One end of the bottom trough 102 is connected to a drain trough 103 for collecting cleaning wastewater. Figure 1 and Figure 2 As shown, adjustable support legs 104 are installed at the four corners of the bottom of the main body 101. The support legs 104 are telescopic structures, such as telescopic rods with locking structures. The angle of the conveyor box can be adjusted by extending and retracting the support legs 104 to adapt to the conveying requirements of different positions. The support legs 104 and the main body 101 are rotatably connected. Due to the weight of the sewage trough 103 and the extension and retraction of the telescopic sleeve, the end of the bottom trough 102 with the sewage trough 103 installed is always on the lower side, which facilitates the flow of waste liquid generated by cleaning liquid and clean water into the interior of the sewage trough 103. A plastic sewage valve is installed at the bottom of the sewage trough 103, which can realize the real-time or timed discharge of cleaning sewage.
[0024] The limiting plate 7 is fixedly installed inside the conveyor box. The limiting plate 7 is positioned above the conveyor belt 1 to confine the meatball inside the conveyor trough. The limiting plate 7 is horizontally suspended directly above the conveyor belt 1. The distance between its bottom end and the surface of the conveyor belt 1 is less than the diameter of the meatball and slightly higher than the top of the meatball located in the conveyor trough. This just confines the meatball inside the conveyor trough, preventing the meatball from bouncing and rolling down, and avoiding damage caused by squeezing the meatball.
[0025] To ensure that the meatballs enter the conveyor trough one by one, anti-fall plates 8 and arranging plates 9 are respectively installed on both sides of the bottom end of the feeding channel 5 along the direction of the conveyor belt 1. Two side plates for blocking the meatballs are fixed between the anti-fall plates 8 and the arranging plates 9. The anti-fall plates 8 are used to prevent the meatballs from rolling backward. The bottom ends of the arranging plates 9 and the limiting plates 7 are flush. The arranging plates 9 block the meatballs on the surface of the conveyor belt 1 and make the meatballs falling into the conveyor trough move forward with the conveyor belt 1. There is a gap between the bottom end of the anti-fall plates 8 and the conveyor belt 1 smaller than the meatballs. The gap in the diameter of the meatballs can block them from falling backward. The arranging plate 9 and the limiting plate 7 are slightly higher than the height of the meatballs in the conveying trough. The distance between the arranging plate 9 and the limiting plate 7 and the conveyor belt 1 is less than the diameter of the meatballs. This allows the meatballs falling into the conveying trough to pass through the arranging plate 9 and block the meatballs above the conveyor belt 1. This allows the meatballs to slide orderly into the interior of the conveying trough as the conveyor belt 1 rotates, ensuring the regularity of the feeding. The meatballs are inside the hemispherical conveying trough, which can ensure the stable conveying of the meatballs.
[0026] The scraper 10 is fixedly installed on the outside of the conveyor belt 1. The scraper 10 and the conveyor troughs are staggered, that is, a scraper 10 is set between two adjacent rows of conveyor troughs. The scraper 10 can separate the meatballs. At the same time, the scraper 10 moves with the conveyor belt 1 to scrape the surface of the limiting plate 7 and the baffle 2. The scraper 10 is elastic and can be made of food-grade silicone. The height of the scraper 10 is higher than the conveyor belt 1. Its top end is tightly attached to the bottom end of the limiting plate 7, and its two sides are tightly attached to the inner side of the baffle 2. When the conveyor belt 1 is running, the scraper 10 can move synchronously with the conveyor belt 1. On the one hand, it separates the meatballs in the adjacent conveyor troughs to prevent the meatballs from getting stuck and falling due to mutual squeezing. On the other hand, it can thoroughly scrape the juice adhering to the surface of the limiting plate 7 and the baffle 2 and send it to the cleaning area below for unified treatment with the conveyor belt 1. In addition, the scraper 10 is made of elastic material and can bend when passing through the anti-fall plate 8 to avoid obstructing the operation of the scraper 10 and the conveyor belt 1.
[0027] To preserve the meatballs during transport, a cold air box 11 is also included. The cold air box 11 is connected to the conveyor box via multiple cold air pipes 12. The cold air box 11 is also connected to an external refrigeration device. The external refrigeration device supplies cold air into the interior of the cold air box 11 and sends it into the interior of the conveyor box through the cold air pipes 12. The air outlet of the cold air pipe 12 is located between the limiting plate 7 and the baffle 2. The air can be blown into the conveying area through the gap between the limiting plate 7 and the baffle 2, effectively inhibiting the growth of microorganisms on the surface of the meatballs and slowing down the spoilage of the meatballs.
[0028] like Figures 3 to 6 As shown, the cleaning pipe 13 is located below the conveyor belt 1. The cleaning pipe 13 has a nozzle for spraying cleaning liquid onto the surface of the conveyor belt 1 and the scraper 10. The rinsing pipe 14 is located below the conveyor belt 1. The rinsing pipe 14 has a nozzle for spraying clean water onto the surface of the conveyor belt 1 and the scraper 10. Both the cleaning pipe 13 and the rinsing pipe 14 are seamless stainless steel pipes. They are fixedly installed parallel to each other in the cleaning area below the conveyor belt 1. The cleaning pipe 13 is located on the side closer to the discharge channel 6, and the rinsing pipe 14 is located on the side closer to the feed channel 5. The pipe wall of the cleaning pipe 13 is evenly distributed with atomizing nozzles facing the conveyor belt 1 and the scraper 10 for spraying food-grade alkaline cleaning liquid to decompose grease and protein juice. The pipe wall of the rinsing pipe 14 is correspondingly provided with clean water nozzles for spraying clean water to rinse away residual cleaning liquid and small impurities. The liquid inlet ends of both the cleaning pipe 13 and the rinsing pipe 14 extend to the outside of the conveyor box and are connected to the liquid delivery pipe 15.
[0029] To reduce the impact of cleaning fluid and water on meatball transport, a partition 16 is fixedly installed inside the conveyor box. The partition 16 is located in the middle between the upper and lower layers of the conveyor belt 1 to separate the conveying side and the idle side of the conveyor belt 1. The partition 16 can separate the upper conveying area and the lower cleaning area of the conveyor belt 1, preventing the cleaning fluid and water in the cleaning area from spraying into the conveying area and affecting the meatballs. The partition 16 is located between the driving roller 3 and the driven roller 4 to avoid affecting the operation of the conveyor belt 1.
[0030] The wiping shaft 17 is rotatably mounted inside the conveyor box, located below the conveyor belt 1. An absorbent roller 18, made of sponge material, is mounted outside the wiping shaft 17 to wipe and absorb liquid from the surface of the conveyor belt 1 and the scraper 10. The absorbent roller 18 can penetrate deep into the conveyor trough to wipe and dry the surface. Two sets of wiping shafts 17 are provided: a cleaning pipe 13, one set of wiping shafts 17, a rinsing pipe 14, and another set of wiping shafts 17 are sequentially arranged below the conveyor belt 1 along its running direction. Each set contains two wiping shafts 17, which work alternately. A drying mechanism for drying the absorbent rollers 18 is provided on the conveyor box. The drying mechanism includes a drying cylinder 201. The drying cylinder 201 consists of a heating jacket 202 and an opening / closing plate 203. Two sets of drying cylinders 201 are provided, with two cylinders in each set. Each drying cylinder 201 corresponds to a wiping shaft 17. The two drying cylinders 201 are located on both sides of the conveyor box and are connected to it. The wiping shaft 17 is movably located inside the conveyor box. When one wiping shaft 17 is below the conveyor belt 1, the other wiping shaft 17 is located inside the drying cylinder 201. The heating jacket 202 is located outside the drying cylinder 201 and contains a heater connected to an external temperature controller. The temperature control range is 40-60℃, ensuring drying efficiency while preventing excessive temperature from aging the absorbent roller 18. A useful opening is provided on the drying cylinder 201. The opening and closing plate 203 is movably installed inside the conveyor box at the steam exhaust port. It is used to open and close the drying cylinder 201 when the wiping shaft 17 enters and exits the drying cylinder 201. There are four sets of opening and closing plates 203, and each set includes two plates. The opening and closing of the same set of opening and closing plates 203 opens and closes the same drying cylinder 201. The four opening and closing plates 203 moving in the same direction are fixedly connected by a connecting frame. Two electric cylinders 204 are installed inside the conveyor box. The output end of each electric cylinder 204 is fixedly connected to the four opening and closing plates 203 moving in the same direction. The extension and retraction of the electric cylinders 204 can drive the multiple opening and closing plates 203 to move closer or further away from each other to open and close the drying cylinder 201. To prevent heat loss from the drying cylinder 201 and to prevent moisture and impurities from entering the drying cylinder 201 in the cleaning area, an electric cylinder 20 is installed on one of the drying cylinders 201 in each group of drying cylinders 201 to enable the movement and rotation of the wiping shaft 17. The output end of the electric cylinder 20 extends axially into the drying cylinder 201 and is fixedly mounted with a motor 21. The end of the wiping shaft 17 is fixedly connected to the output end of the motor 21 through a coupling. The electric cylinder 20 can drive the wiping shaft 17 to move axially back and forth, realizing the switching of the working positions of the two wiping shafts 17. The motor 21 can drive the wiping shaft 17 to rotate, causing the water absorption roller 18 to perform reverse frictional motion with the conveyor belt 1, thereby improving the wiping and absorption effect.
[0031] like Figure 8As shown, to replace the absorbent roller 18, a replacement sleeve 19 is slidably installed on the outside of the wiping shaft 17. The replacement sleeve 19 is detachably connected to the wiping shaft 17 by bolts. The absorbent roller 18 is fixedly installed on the outside of the replacement sleeve 19. The replacement sleeve 19 and the wiping shaft 17 can be disassembled and assembled by bolts. The bolts are located at the end of the wiping shaft 17 away from the motor 21, and the end of the drying cylinder 201 corresponding to this end is a threaded cover plate. The cover plate can be removed from the drying cylinder 201 periodically. By unscrewing the bolts to disconnect the replacement sleeve 19 and the wiping shaft 17, the replacement sleeve 19 can be pulled off the wiping shaft 17, thereby removing the absorbent roller 18 from the wiping shaft 17 for replacement. The new replacement sleeve 19 is slidably installed on the wiping shaft 17, and the two are fixedly connected by bolts.
[0032] To prevent the cleaning fluid and water from freezing, both the cleaning pipe 13 and the rinsing pipe 14 are connected to a liquid delivery pipe 15. The liquid delivery pipe 15 is wrapped around the outside of the heating jacket 202. The residual heat of the heating jacket 202 is used to heat the liquid in the liquid delivery pipe 15, thereby reusing the heat source, saving energy consumption, preventing the cleaning fluid and water from freezing, ensuring their normal flow, and thus ensuring the cleaning effect on the conveyor belt 1 and the scraper 10.
[0033] The working principle or usage process of the anti-drop conveyor device for meatball production is as follows: Start the drive motor 21 of the conveyor belt 1, adjust the conveyor belt 1 to the set operating speed, start the external refrigeration equipment, and deliver cold air to the conveying chamber of the conveyor box through the cold air box 11 and the cold air pipe 12 to adjust the temperature of the conveying chamber to the preservation temperature. Start the heater of the drying component, and the heating jacket 202 starts to heat up to heat the liquid delivery pipe 15 wrapped around it to prevent the cleaning liquid and water from freezing. Start the motor 21 to drive the wiping shaft 17 and the water absorption roller 18 to rotate and wipe the conveyor belt 1 and the scraper 10.
[0034] Meatballs enter the feeding channel 5 from the previous process. Under the action of gravity, the meatballs fall onto the surface of the conveyor belt 1. The anti-fall plate 8 at the feeding end prevents the meatballs from rolling backward. The arranging plate 9 guides the meatballs to fall into the conveying trough of the conveyor belt 1 in an orderly manner, realizing single-piece limiting. The operation of the conveyor belt 1 drives the meatballs to be conveyed forward. The limiting plate 7 limits the meatballs in the conveying trough from above. The baffle 2 provides blocking on both sides. The scraper 10 separates the meatballs in adjacent conveying troughs to prevent the meatballs from squeezing and getting stuck. Under the action of the multi-layer limiting structure, the meatballs move smoothly along the conveyor belt 1 to the discharge channel 6 without the risk of rolling or bouncing off. During the operation of the conveyor belt 1, the scraper blades 10, which are interleaved with the conveyor trough, move synchronously. The top of the scraper blades 10 is attached to the bottom of the limiting plate 7, and the two sides are attached to the inner side of the baffle 2. During the movement, the meatball juice adhering to the surface of the limiting plate 7 and the baffle 2 is thoroughly scraped and swept away. The scraper blades 10 enter the cleaning chamber of the conveyor box, realizing the real-time scraping and removal of impurities from the anti-drop components during the conveying process, and avoiding the accumulation of impurities. After the conveyor belt 1 carrying impurities and juices enters the cleaning chamber, it first passes through the cleaning pipe 13 along the direction of its rotation. The nozzles of the cleaning pipe 13 spray food-grade cleaning liquid onto the surface of the conveyor belt 1 and the scraper 10, breaking down the grease, protein, and juices. The decomposed impurities mix with the cleaning liquid and fall into the bottom trough 102. Then, the conveyor belt 1 passes through the first set of wiping shafts 17. The motor 21 drives the wiping shafts 17 to rotate, and the absorbent roller 18 closely contacts the lower surface of the conveyor belt 1 and the scraper 10, further cleaning the surface of the conveyor belt 1 and the scraper 10 with the cleaning liquid and impurities. First, the conveyor belt 1 is wiped with water to achieve initial cleaning and liquid removal. Then, the conveyor belt 1 passes through the rinsing pipe 14, where the nozzles spray clean water to wash away the residual cleaning liquid and small impurities on the surface of the conveyor belt 1 and the scraper 10. The clean water and impurities fall into the bottom trough 102. After that, the conveyor belt 1 passes through the second set of wiping shafts 17, and the water suction roller 18 performs a second water suction and wiping on the conveyor belt 1 and the scraper 10 to ensure that there is no liquid residue on the surface of the conveyor belt 1 and the scraper 10. The cleaning wastewater in the bottom trough 102 flows into the drain trough 103 along the bottom trough 102 and is discharged uniformly through the drain valve. After a certain period of time, the wiping shaft 17 that has completed the water absorption and wiping is moved into the drying cylinder 201 under the drive of the electric cylinder 20. Another set of wiping shafts 17 moves to the bottom of the conveyor belt 1 for wiping. When the wiping shaft 17 is replaced, the opening and closing plate 203 moves to open the drying cylinder 201. After the replacement is completed, the connection between the drying cylinder 201 and the cleaning chamber is closed. The heat generated by the heating sleeve 202 dries the water absorption roller 18. The dried wiping shaft 17 is in standby mode and works alternately with another set of wiping shafts 17 to ensure the continuity of the cleaning process. Throughout the meatball transport process, low-temperature cold air is continuously transported into the transport chamber through the cold air pipe 12, keeping the transport chamber in a low-temperature preservation environment. This effectively inhibits the growth of microorganisms on the surface of the meatballs, slows down the decline in meatball quality, and achieves low-temperature preservation transport of the meatballs. In addition, the partition 16 separates the transport chamber from the cleaning chamber, reducing the impact of cold air entering the cleaning chamber on the cleaning process. The meatballs move smoothly to the discharge channel 6 under the drive of the conveyor belt 1, are discharged from the discharge channel 6 and enter the next process. The cleaned and dried conveyor belt 1 re-enters the conveying chamber to continue the task of conveying meatballs.
[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
