Description

Technical Field

[0001] This invention relates to the field of conveying and sterilizing equipment, specifically to a conveying and sterilizing equipment and method for pre-packaged spicy chicken. Background Technology

[0002] Sterilization equipment refers to machines that kill microorganisms on products, packaging containers, packaging materials, packaging aids, and packaging components, reducing them to within permissible limits. In the processing of pre-packaged foods, sterilization is necessary before packaging to ensure food safety and effectively extend shelf life.

[0003] According to publicly available patent CN221931199U, a pre-packaged food conveying and sterilization device relates to the field of sterilization equipment. This device includes a sterilization unit with a sterilization-sealed shell. A conveyor belt is driven onto the sterilization unit and is located inside the sterilization-sealed shell. A transmission unit is provided on the sterilization-sealed shell. When the conveyor belt carries the food, it drives a connecting sprocket to rotate. The rotation of the sprocket, in turn, drives a turning rod via a chain. This rotation of the turning rod flips the food on the conveyor belt that is in contact with it, sterilizing the food at the bottom and preventing food obscured by upper layers from having poor sterilization effects and potential safety hazards.

[0004] However, in practice, traditional pre-packaged food conveying and sterilization equipment mostly only sterilizes the surface of the food. Even if a turning mechanism is included, it only serves to turn the food over. The food cannot be thoroughly sterilized simultaneously during the turning process, easily creating sterilization dead zones and affecting the uniformity of sterilization. Furthermore, grease and seasonings on the surface of spicy chicken easily adhere to the turning parts, which, over time, affects the turning effect and increases cleaning and maintenance workload. Therefore, it is difficult to meet the needs of continuous, high-quality production of pre-packaged spicy chicken. Therefore, a new technical solution is needed to address this issue. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a conveying and sterilization device and method for pre-packaged spicy chicken food. This addresses the problem that most traditional pre-packaged food conveying and sterilization devices can only sterilize the surface of the food. Even if a flipping mechanism is provided, it only serves to turn the food over. The food cannot be fully sterilized simultaneously during the flipping process, which easily creates sterilization dead zones and affects the uniformity of sterilization. At the same time, the oil and seasonings on the surface of spicy chicken food easily adhere to the surface of the flipping parts, which will affect the flipping effect and increase the workload of cleaning and maintenance after long-term use. Therefore, it is difficult to meet the technical problem of meeting the needs of continuous and high-quality production of pre-packaged spicy chicken food.

[0006] To achieve the objectives of this invention, the technical solution adopted is as follows: A pre-packaged spicy chicken food conveying and sterilization device is designed, comprising:

[0007] The conveying unit is located between the first connecting plate and the second connecting plate and is used to convey pre-packaged spicy chicken food.

[0008] At least two disinfection sections are symmetrically arranged on the top of the conveying section and distributed sequentially along the conveying direction, for disinfecting the pre-packaged spicy chicken food during the conveying process;

[0009] The rotating part, located between the two sterilization parts and above the conveying part, is used to turn over the pre-packaged spicy chicken food conveyed by the conveying part and to spray steam into the food for sterilization during the turning process.

[0010] The transmission unit is located between the conveying unit and the rotating unit, and is used to transmit the driving force generated by the conveying unit during operation to the rotating unit so as to drive the rotating unit to rotate.

[0011] Preferably, the conveying section includes a conveyor belt located between the first connecting plate and the second connecting plate. A first rotating roller is sleeved inside the conveying section at one end. One end of the first rotating roller passes through the first connecting plate and is connected to the output shaft of a dual-axis motor mounted on the outer side of the first connecting plate. The other end of the first rotating roller is connected to a first bearing mounted on the inner side of the second connecting plate. Multiple second rotating rollers are sleeved inside the other end of the conveyor belt. Both ends of the multiple second rotating rollers are connected to second bearings, and the multiple second bearings are respectively mounted on the inner sides of the first connecting plate and the second connecting plate.

[0012] Preferably, the disinfection section includes a concave plate, which is installed on the top of the first connecting plate and the second connecting plate, and a disinfection box is installed at its bottom. The disinfection box has openings on both sides, and soft curtains are installed at the openings.

[0013] Preferably, the disinfection chamber is equipped with multiple ultraviolet disinfection lamps at the top inside, and a first air pump is installed at the top of the chamber. The air outlet at the bottom of the first air pump is connected to a first air outlet pipe, the bottom of the first air outlet pipe extends into the disinfection chamber, and the air inlet at the top of the first air pump is connected to a first air inlet pipe. The other end of the first air inlet pipe communicates with the inner cavity of the steam chamber.

[0014] Preferably, the rotating part includes a rotating tube body, one end of which is connected to a second air outlet pipe, and the other end is a sealed structure, and is connected to a third bearing installed on the inner side of a second connecting plate body via a connecting rod body. The other end of the second air outlet pipe passes through the first connecting plate body and is connected to the stationary ring end of the rotating joint. The other end of the rotating joint is connected to a second air inlet pipe, which is connected to a second air pump installed on the surface of the steam box body. The air inlet end of the second air pump communicates with the inner cavity of the steam box body.

[0015] Preferably, the outer periphery of the rotating tube is provided with multiple sets of air outlets, each set having multiple air outlets, and all multiple air outlets are axially arranged on the outer periphery of the rotating tube. Multiple tilting buckets are evenly distributed around the outer periphery of the rotating tube, and the multiple tilting buckets are correspondingly arranged with the multiple sets of air outlets. The surface of the tilting bucket is provided with multiple through holes, which extend into the storage cavity of the tilting bucket. A mesh is installed at the opening of the storage cavity. Multiple air outlets extend into the multiple through holes, so that the steam ejected from the air outlets enters the storage cavity of the tilting bucket through the through holes to disinfect the food scooped up by the tilting bucket during the tilting process.

[0016] Preferably, both ends of the tilting bucket are provided with arc-shaped holes. One end of a spring is installed in a guide groove provided on the inner wall of the arc-shaped hole, and the other end of the spring is connected to a movable rod. One end of the movable rod extends into the tilting bucket and connects with a concave scraper located inside the tilting bucket. The other end extends out of the tilting bucket and is used to abut against a torsion member installed on the inner side of the first connecting plate and the second connecting plate, thereby driving the movable rod to move along the arc-shaped hole, so that the scraper scrapes off the attached food along the arc inside the tilting bucket.

[0017] Preferably, the torsion member includes a fixed plate, and multiple limiting plates are symmetrically fixed to one end of the fixed plate facing the tilting bucket. A support rod is connected between the multiple limiting plates, and a torsion spring is installed on the outside of the support rod. The torsion end of the torsion spring is connected to the torsion plate, and the torsion plate is correspondingly arranged with multiple movable rods extending into the tilting bucket.

[0018] Preferably, the transmission unit includes a first pulley, which is connected to the output shaft at the other end of the dual-axis motor, and a transmission belt is sleeved on its outside. A second pulley is sleeved on the other end of the transmission belt, and the second pulley passes through and is fixed to the outside of the rotary joint to drive the rotary joint to rotate.

[0019] A method for sterilizing pre-packaged spicy chicken during transportation is also provided, comprising the following steps:

[0020] S1. Add an appropriate amount of water to the steam chamber and replenish the liquid through the liquid pipe. After completion, seal the chamber with the pipe cap to generate steam that meets the disinfection requirements.

[0021] S2. Start the dual-shaft motor. The dual-shaft motor drives the conveyor belt to run and drives the rotating part to rotate synchronously through the transmission part. During the rotation of the rotating part, the tipping bucket rotates synchronously with the rotating tube body. The torsion plate body is kept facing the tipping bucket side under the action of the torsion spring.

[0022] S3. Place the pre-packaged spicy chicken food to be sterilized on the surface of the conveyor belt. The food enters the front sterilization chamber with the conveyor belt. The ultraviolet sterilization lamp irradiates the food for sterilization. At the same time, the first air pump delivers steam to the front sterilization chamber for steam-assisted sterilization of the food.

[0023] S4. After the food is moved to the rotating part, the tipping bucket scoops up the food and lifts it upwards. The second air pump delivers steam to the inside of the rotating tube, which is then sprayed out through multiple air outlets and enters the inside of the tipping bucket through the through holes to steam sterilize the food, thus achieving simultaneous tipping and sterilization.

[0024] S5. The tipping bucket continues to rotate and flips the food over, releasing it onto the surface of the conveyor belt. This exposes the parts of the food that were originally covered or in contact with the conveyor belt. The food then enters the rear disinfection chamber and is disinfected again by a combination of ultraviolet light and steam, achieving multi-angle and all-round sterilization of the food.

[0025] S6. When the tipping bucket rotates to the position of the torsion member, the movable rod extending outside the tipping bucket contacts the torsion plate and pushes the torsion plate to rotate around the support rod, causing the torsion spring to undergo torsional deformation. At the same time, the movable rod moves along the arc-shaped hole and compresses the spring, thereby driving the scraper to slide along the inner wall of the tipping bucket to scrape off the attached grease, seasonings and residues. When the movable rod disengages from the torsion plate, the torsion spring releases its elastic potential energy and drives the torsion plate to reset. At the same time, the spring pushes the movable rod and the scraper back to their initial positions, completing the automatic cleaning of the tipping bucket.

[0026] S7. After sterilization, the food continues to be conveyed forward along the conveyor belt and discharged from the equipment to enter the subsequent packaging process, completing the conveying and sterilization process of the pre-packaged spicy chicken food.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. This invention, through the cooperation of the conveying unit, rotating unit, disinfection unit, and transmission unit, can automatically flip the spicy chicken during the food conveying process, exposing the parts of the food that were originally in contact with or covered by the conveyor belt, and then disinfecting them again after flipping. This reduces sterilization blind spots caused by partial obstruction, improves the overall sterilization uniformity of the food, and ensures the processing quality and food safety of pre-packaged food.

[0029] 2. This invention, by setting a steam conveying structure inside the rotating part and using multiple air outlets in conjunction with the tilting bucket, enables food to continuously receive steam sterilization treatment during the process of being scooped up, lifted, and tilted. Compared with the traditional method of tilting before sterilization, this invention can carry out the tilting process and the sterilization process simultaneously, improving steam utilization efficiency, shortening sterilization time, and improving the overall working efficiency of the equipment.

[0030] 3. By setting up a movable rod, scraper, spring and torsion component, when the tilting bucket rotates to the designated position, the torsion component can push the movable rod to move along the arc-shaped hole, thereby driving the scraper to scrape and clean the inside of the tilting bucket, removing the attached grease, seasonings and food residue in time, avoiding long-term accumulation that affects the tilting effect, while reducing the frequency of manual cleaning and improving the continuous operation capability of the equipment.

[0031] 4. This invention transmits power synchronously to the rotating part through the transmission part, so that the conveying and flipping actions are linked. Food flipping and auxiliary sterilization functions can be realized without the need to add a separate drive mechanism. This not only makes the equipment structure more compact, but also helps to reduce equipment energy consumption and maintenance costs, and improve the stability and reliability of the production line operation.

Detailed Implementation

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0040] Example 1: A conveying and sterilization device and method for pre-packaged spicy chicken food, see [link to example]. Figures 1 to 6 ,include:

[0041] Conveying unit 2 is disposed between the first connecting plate 101 and the second connecting plate 102, and is used to convey pre-packaged spicy chicken food.

[0042] At least two disinfection sections 5 are symmetrically arranged on the top of the conveying section 2 and distributed sequentially along the conveying direction, for disinfecting the pre-packaged spicy chicken food during the conveying process;

[0043] The rotating part 4 is located between the two disinfection parts 5 and above the conveying part 2. It is used to flip the pre-packaged spicy chicken food conveyed by the conveying part 2 and spray steam into the food for disinfection during the flipping process.

[0044] The transmission unit 3 is disposed between the conveying unit 2 and the rotating unit 4, and is used to transmit the driving force generated by the conveying unit 2 during operation to the rotating unit 4 so as to drive the rotating unit 4 to rotate.

[0045] In use, the pre-packaged spicy chicken is placed on the surface of the conveyor belt 202, and the dual-axis motor 201 is started. One end of the dual-axis motor 201 outputs power to drive the first rotating roller 203 to rotate. With the cooperation of the first rotating roller 203 and multiple second rotating rollers 206, the conveyor belt 202 is driven to run continuously, thereby realizing the conveying of food. At the same time, the other end of the dual-axis motor 201 outputs power to drive the first pulley 301 to rotate. The first pulley 301 drives the second pulley 303 and the rotary joint 410 to rotate synchronously through the transmission belt 302, so that the rotating tube 403 rotates continuously.

[0046] For details, see Figure 1 and Figure 3 The conveying unit 2 includes a conveyor belt 202, which is located between the first connecting plate 101 and the second connecting plate 102. A first rotating roller 203 is sleeved on one end of the conveying unit 2. One end of the first rotating roller 203 passes through the first connecting plate 101 and is connected to the output shaft of a dual-axis motor 201 installed on the outer side of the first connecting plate 101. The other end is connected to a first bearing 204 installed on the inner side of the second connecting plate 102. A plurality of second rotating rollers 206 are sleeved on the other end of the conveyor belt 202. Both ends of the plurality of second rotating rollers 206 are connected to second bearings 205, and the plurality of second bearings 205 are respectively installed on the inner sides of the first connecting plate 101 and the second connecting plate 102.

[0047] Further, see Figure 1 and Figure 4 The disinfection unit 5 includes a concave plate 501, which is installed on the top of the first connecting plate 101 and the second connecting plate 102, and a disinfection box 504 is installed at its bottom. The disinfection box 504 has openings on both sides, and soft curtains 505 are installed at the openings. Multiple ultraviolet disinfection lamps 507 are installed at the top inside the disinfection box 504, and a first air pump 503 is installed at its top. The air outlet end of the first air pump 503 is connected to a first air outlet pipe 506, and the bottom of the first air outlet pipe 506 extends into the disinfection box 504. The air inlet end of the first air pump 503 is connected to a first air inlet pipe 502, and the other end of the first air inlet pipe 502 is connected to the inner cavity of the steam box 1.

[0048] Food first enters the front disinfection chamber 504 via conveyor belt 202. Ultraviolet disinfection lamps 507 perform the first disinfection treatment on the food surface. Simultaneously, steam generated in the steam chamber 1 is transported to the front disinfection chamber 504 via the first air inlet pipe 502, the first air pump 503, and the first air outlet pipe 506, allowing the food to undergo combined steam and ultraviolet disinfection during transport, improving the sterilization effect. When the food reaches the rotating section 4, the tilting bucket 406 on the outer periphery of the rotating tube 403 scoops up the food and lifts it upwards. At the same time, the second air pump... Steam from the steam chamber 1 is transported to the rotating tube 403 via the second air inlet pipe 402, rotary joint 410, and second air outlet pipe 404. The steam is then ejected from multiple air outlets 407. The steam enters the storage chamber through the through-holes 408 on the tipping bucket 406, continuously steam-sterilizing the food being scooped up. This ensures simultaneous sterilization during the tipping process. As the rotating tube 403 continues to rotate, the tipping bucket 406 flips the food and it falls back onto the surface of the conveyor belt 202, exposing the areas that were previously in contact with the conveyor belt. The flipped food then continues to enter the rear sterilization chamber 504 along the conveyor belt 202, where it undergoes further combined ultraviolet and steam sterilization, reducing sterilization dead zones and improving the overall uniformity of food sterilization.

[0049] It is worth noting that, see Figure 1 and Figure 5 The rotating part 4 includes a rotating tube 403. One end of the rotating tube 403 is connected to a second air outlet pipe 404, and the other end is a sealed structure, connected to a third bearing 405 mounted on the inner side of the second connecting plate 102 via a connecting rod. The other end of the second air outlet pipe 404 passes through the first connecting plate 101 and is connected to the stationary ring end of the rotary joint 410. The other end of the rotary joint 410 is connected to a second air inlet pipe 402. The second air inlet pipe 402 is connected to a second air pump 401 mounted on the surface of the steam box 1. The air inlet end of the second air pump 401 communicates with the inner cavity of the steam box 1. Multiple sets of air outlet pipe heads 407 are provided on the outer periphery of the rotating tube 403. There are multiple heads 407, and multiple air outlet heads 407 are axially arranged on the outer periphery of the rotating tube body 403. Multiple tilting buckets 406 are evenly distributed around the outer periphery of the rotating tube body 403. Multiple tilting buckets 406 are correspondingly arranged with multiple sets of air outlet heads 407. Multiple through holes 408 are provided on the surface of the tilting buckets 406. Multiple through holes 408 extend into the storage cavity of the tilting buckets 406. A partition net 409 is installed at the opening of the storage cavity. Multiple air outlet heads 407 are inserted into the multiple through holes 408, so that the steam sprayed from the air outlet heads 407 enters the storage cavity of the tilting buckets 406 through the through holes 408 to disinfect the food scooped up by the tilting buckets 406 during the tilting process.

[0050] It is worth noting that, see Figure 5 Both ends of the tilting bucket 406 are provided with arc-shaped holes 411. One end of a spring 412 is installed in the guide groove provided on the inner wall of the arc-shaped hole 411. The other end of the spring 412 is connected to a moving rod 413. One end of the moving rod 413 extends into the tilting bucket 406 and is connected to a concave scraper 414 located inside the tilting bucket 406. The other end extends out of the tilting bucket 406 and is used to abut against the torsion member installed on the inner side of the first connecting plate 101 and the second connecting plate 102, thereby driving the moving rod 413 to move along the arc-shaped hole 411, so that the scraper 414 scrapes off the attached food along the arc inside the tilting bucket 406.

[0051] It is worth mentioning that, see Figure 6 The torsion component includes a fixed plate 415, with multiple limiting plates symmetrically fixed to one end of the fixed plate 415 facing the tilting bucket 406. A support rod 416 is connected between the multiple limiting plates. A torsion spring 417 is installed on the outside of the support rod 416. A torsion plate 418 is connected to the torsion end of the torsion spring 417. The torsion plate 418 is correspondingly set with multiple movable rods 413 extending out of the tilting bucket 406.

[0052] During the rotation of the tilting bucket 406, the movable rod 413 extending outside the bucket contacts the torsion plate 418, pushing the movable rod 413 to move along the arc-shaped hole 411 and compressing the spring 412, thereby driving the scraper 414 to slide along the inner wall of the tilting bucket 406, scraping off the grease, seasonings and food residues attached to the inner side of the bucket. When the movable rod 413 disengages from the torsion plate 418, it returns to its original position under the reset action of the spring 412, realizing the automatic cleaning of the tilting bucket 406, ensuring the tilting effect and the stability of equipment operation.

[0053] It is worth emphasizing that, see Figure 1 The transmission unit 3 includes a first pulley 301, which is connected to the output shaft of the other end of the dual-axis motor 201. A transmission belt 302 is sleeved on its outside. A second pulley 303 is sleeved on the other end of the transmission belt 302. The second pulley 303 is fixed through and fixed to the outside of the rotary joint 410 to drive the rotary joint 410 to rotate.

[0054] It is worth noting that, see Figure 1 The top of the steam box 1 is symmetrically connected with a first connecting plate 101 and a second connecting plate 102, and both the upper and lower ends of one side are connected with liquid pipes 103. The other end of the liquid pipe 103 is equipped with a pipe cover 104. Multiple electric heating tubes are installed inside the steam box 1 to heat the liquid inside and generate hot steam.

[0055] A method for sterilizing pre-packaged spicy chicken during transportation is also provided, comprising the following steps:

[0056] S1. Add an appropriate amount of water to the steam chamber 1 and replenish the liquid through the liquid pipe 103. After completion, seal the chamber with the pipe cap 104 so that the steam chamber 1 generates steam that meets the disinfection requirements.

[0057] S2. Start the dual-shaft motor 201. The dual-shaft motor 201 drives the conveyor belt 202 to run and drives the rotating part 4 to rotate synchronously through the transmission part 3. During the rotation of the rotating part 4, the tipping bucket 406 rotates synchronously with the rotating tube 403. The torsion plate 418 is kept facing the tipping bucket 406 under the action of the torsion spring 417.

[0058] S3. Place the pre-packaged spicy chicken food to be sterilized on the surface of the conveyor belt 202. The food enters the front disinfection box 504 along with the conveyor belt 202. The ultraviolet disinfection lamp 507 irradiates and disinfects the food. At the same time, the first air pump 503 delivers steam to the front disinfection box 504 to perform steam-assisted disinfection of the food.

[0059] S4. After the food is moved to the position of the rotating part 4, the tipping bucket 406 scoops up the food and lifts it upwards. The second air pump 401 delivers steam to the inside of the rotating tube 403, which is then sprayed out through multiple air outlets 407 and enters the inside of the tipping bucket 406 through the through hole 408 to steam sterilize the food, so that tipping and sterilization are carried out simultaneously.

[0060] S5. The tipping bucket 406 continues to rotate and flips the food over, releasing it onto the surface of the conveyor belt 202. This exposes the parts of the food that were originally covered or in contact with the conveyor belt 202. The food then enters the rear disinfection chamber 504 and is subjected to combined ultraviolet light and steam disinfection again, achieving multi-angle and all-round sterilization of the food.

[0061] S6. When the tipping bucket 406 rotates to the position of the torsion member, the movable rod 413 extending outside the tipping bucket 406 contacts the torsion plate 418 and pushes the torsion plate 418 to rotate around the support rod 416, causing the torsion spring 417 to undergo torsional deformation. At the same time, the movable rod 413 moves along the arc-shaped hole 411 and compresses the spring 412, thereby driving the scraper 414 to slide along the inner wall of the tipping bucket 406 to scrape off the attached grease, seasonings and residues. When the movable rod 413 disengages from the torsion plate 418, the torsion spring 417 releases its elastic potential energy and drives the torsion plate 418 to reset. At the same time, the spring 412 pushes the movable rod 413 and the scraper 414 back to their initial positions, completing the automatic cleaning of the tipping bucket 406.

[0062] S7. After sterilization, the food continues to be conveyed forward along conveyor belt 202 and discharged from the equipment to enter the subsequent packaging process, completing the conveying and sterilization process of the pre-packaged spicy chicken food.

[0063] In addition, all components designed in this invention are general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this invention does not involve improvements to the internal structure and method.

10. A method for conveying and sterilizing pre-packaged spicy chicken food, applicable to the pre-packaged spicy chicken food conveying and sterilizing equipment according to any one of claims 1-9, characterized in that, Includes the following steps: S1. Add an appropriate amount of water to the steam chamber (1) and replenish the liquid through the liquid pipe (103). After completion, seal the chamber with the pipe cap (104) so ​​that the steam chamber (1) generates steam that meets the disinfection requirements. S2. Start the dual-shaft motor (201). The dual-shaft motor (201) drives the conveyor belt (202) to run and drives the rotating part (4) to rotate synchronously through the transmission part (3). During the rotation of the rotating part (4), the tipping bucket (406) rotates synchronously with the rotating tube (403), and the torsion plate (418) is kept facing the tipping bucket (406) under the action of the torsion spring (417). S3. Place the pre-packaged spicy chicken food to be sterilized on the surface of the conveyor belt (202). The food enters the front disinfection box (504) along with the conveyor belt (202). The ultraviolet disinfection lamp (507) irradiates and disinfects the food. At the same time, the first air pump (503) delivers steam to the front disinfection box (504) to perform steam-assisted disinfection of the food. S4. After the food is moved to the position of the rotating part (4), the tipping bucket (406) scoops up the food and lifts it upward. The second air pump (401) delivers steam to the inside of the rotating tube (403), sprays it out through multiple air outlets (407), and enters the inside of the tipping bucket (406) through the through hole (408) to steam sterilize the food, so that tipping and sterilization are carried out simultaneously. S5. The tipping bucket (406) continues to rotate and flips the food over, releasing it onto the surface of the conveyor belt (202), exposing the parts of the food that were originally covered or in contact with the conveyor belt (202). The food then enters the rear disinfection chamber (504) and is subjected to ultraviolet and steam disinfection again, achieving multi-angle and all-round sterilization of the food. S6. When the tipping bucket (406) rotates to the position of the torsion member, the movable rod (413) extending outside the tipping bucket (406) contacts the torsion plate (418) and pushes the torsion plate (418) to rotate around the support rod (416), causing the torsion spring (417) to undergo torsional deformation. At the same time, the movable rod (413) moves along the arc-shaped hole (411) and compresses the spring (412), thereby driving the scraper (414) to slide along the inner wall of the tipping bucket (406) to scrape off the attached grease, seasonings and residues. When the movable rod (413) disengages from the torsion plate (418), the torsion spring (417) releases its elastic potential energy and drives the torsion plate (418) to reset. At the same time, the spring (412) pushes the movable rod (413) and the scraper (414) back to their initial positions, completing the automatic cleaning of the tipping bucket (406). S7. After sterilization, the food continues to be conveyed forward along the conveyor belt (202) and discharged from the equipment to enter the subsequent packaging process, thus completing the conveying and sterilization process of the pre-packaged spicy chicken food.
