Description

Technical Field

[0001] This invention relates to the field of food processing, specifically to an automated beef pre-cooking equipment. Background Technology

[0002] The process of processing raw beef into snack foods such as beef jerky and braised beef generally involves removing tendons and other impurities from the beef, washing it with water, and then initially boiling the cut beef. After the initial boiling, the beef is taken out for further processing such as steaming, seasoning, and drying or braising, depending on the type of snack food.

[0003] The initial boiling process is to remove blood and other impurities from the meat, thus eliminating any unpleasant odors. This initial boiling process produces a large amount of scum, which consists of blood foam, fat, and impurities. These substances adhere to the beef and can affect the color and taste of subsequent products. Therefore, the scum produced during the initial boiling process must be removed before the beef is taken out of the pot. Summary of the Invention

[0004] The purpose of this invention is to address the above problems by providing an automated beef pre-cooking device that can quickly remove the scum generated during the pre-cooking process.

[0005] To achieve the above objectives, the present invention employs an automated beef pre-cooking device: it includes a pre-cooking unit and a scum removal unit. The pre-cooking unit includes a pre-cooking pot, which is placed on a lifting platform for pre-cooking. The scum removal unit includes a scum removal section, which includes a fixed scum removal plate and a movable scum removal plate arranged vertically. The movable scum removal plate rotates around its vertical rotation axis. The fixed scum removal plate and the movable scum removal plate are provided with through holes arranged in a circular array along the rotation axis of the movable scum removal plate. The pre-cooking pot rises with the lifting platform, so that the scum removal section is immersed below the liquid surface in the pre-cooking pot. The scum generated during the pre-cooking process floats to the liquid surface through the through holes. After the pre-cooking is completed, the through holes on the fixed scum removal plate and the movable scum removal plate are staggered, so that the scum removal section is closed. Subsequently, the pre-cooking pot descends, so that the scum removal section leaves the pre-cooking pot, thereby removing the scum from the pre-cooking pot.

[0006] Furthermore, in order to quickly rinse away the foam on the foam removal section, the foam removal device also includes a transverse moving seat that moves laterally. The transverse moving seat is connected to the foam removal section via a bracket. A cleaning tank is provided below the moving path of the transverse moving seat, and a nozzle facing the inside of the cleaning tank is provided above the cleaning tank. The nozzle sprays cleaning liquid onto the foam removal section, thereby achieving the cleaning effect.

[0007] Furthermore, in order to improve the cleaning effect and reduce cleaning dead spots, the nozzle is mounted on the water pipe, the water pipe rotates around a vertical axis, and the lower part of the water pipe is connected to a rotary joint on the bottom wall of the cleaning tank.

[0008] Furthermore, since the scum removal section will move laterally, in order to prevent the scum on the scum removal section from flowing back into the primary cooking pot or into other production areas during the movement of the scum removal section, a ring of fixed baffles is provided on the outer wall of the fixed scum removal plate, and the outer diameter of the fixed baffles is adapted to the inner diameter of the primary cooking pot.

[0009] Furthermore, when the chopped beef is initially boiled in the initial cooking pot, smaller pieces will float in the water. To minimize waste, the fixed baffle should not sink too deeply during the scum removal process. However, if the fixed baffle sinks too shallowly, the liquid level above the scum removal section will be level with or close to the upper surface of the fixed baffle. As the scum removal section moves, the liquid above it will overflow the fixed baffle. Therefore, it is necessary to control the sinking depth of the scum removal section to ensure that the scum does not... The liquid overflows through the fixed baffle, which is slidably fitted with the movable baffle. The movable baffle is annular and coaxially arranged with the fixed baffle. The upper end of the movable baffle passes through the upper end of the fixed baffle and connects to the lower end of the support. In this way, during the initial boiling process, the fixed baffle descends with the fixed scooping plate, etc., to increase the height difference between the upper end of the movable baffle and the liquid surface above the foam scooping section, thereby reducing the amount of foam overflowing. During the initial boiling process, the fixed baffle is lifted and moved upward to reduce the amount of liquid carried out by the foam scooping section.

[0010] Furthermore, to ensure that the fixed baffle and the movable baffle can slide together and will not separate, the fixed baffle is provided with a ring of concentric insertion holes, and a stop part is provided on the upper part of the inner wall of the ring insertion hole. The lower end of the movable baffle extends into the ring insertion hole and connects with a limiting part whose outer diameter is larger than the inner diameter of the stop part.

[0011] Furthermore, a positioning part is provided on the inner wall of the primary cooking pot to control the descent of the foam removal part, while ensuring that the fixed baffle can be pushed upward during the rising process of the primary cooking pot.

[0012] Furthermore, if warm water is used for initial cooking, the beef will easily become tough and it will not be easy to remove the blood from the beef. Therefore, it is best to use cold water for initial cooking of beef. To improve production efficiency and reduce the waiting time for the initial cooking pot to cool down, a heating tank for heating the initial cooking pot is set on the lifting platform. The top of the heating tank is open. After one initial cooking is completed, a new initial cooking pot is replaced.

[0013] Furthermore, in order to stir the beef during the initial cooking process and ensure that the beef in the initial cooking pot is heated evenly to achieve a better effect of removing the fishy smell, a rotating part concentric with the bottom of the initial cooking pot is provided. A stirring rod is provided on the outer wall of the rotating part. The lower end of the rotating part is open. A transmission shaft driven by a stirring motor is provided on the heating tank. The upper end of the transmission shaft extends into the heating tank. When the initial cooking pot is correctly placed in the heating tank, the transmission shaft is connected to the rotating part.

[0014] Furthermore, to facilitate the sinking of the foam retrieval section in the water, the lower end of the movable retrieval plate is provided with a downwardly protruding arc-shaped part.

[0015] The beneficial effects of this invention are as follows: When or before the initial cooking of beef, the initial cooking pot rises, causing the scum removal section to sink below the liquid surface of the initial cooking pot. At this time, the through hole on the fixed scum removal plate is connected to the through hole on the movable scum removal plate. The scum generated during the initial cooking process will flow along the water flow from the through hole to the top of the scum removal section. After the initial cooking is completed, the movable scum removal plate rotates, causing the through hole on the fixed scum removal plate to be misaligned with the through hole on the movable scum removal plate. At this time, the scum removal section is closed. When the initial cooking pot descends to separate from the scum removal section, the scum generated during the initial cooking process can be quickly removed. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0022] Example 1: As Figures 1-4 As shown, the specific structure of this embodiment is as follows: it includes a pre-cooking device and a foam removal device. The pre-cooking device includes a pre-cooking pot 1, which is placed on a lifting platform 2 for pre-cooking. The foam removal device includes a foam removal section 3, which includes a fixed removal plate 4 and a movable removal plate 5 arranged vertically. The fixed removal plate 4 and the movable removal plate 5 are coaxially arranged, and their vertical position can be selected as needed. In this embodiment, the lower end face of the fixed removal plate 4 is in contact with the upper end face of the movable removal plate 5, and a concentric [something] is provided in the middle of the movable removal plate 5. A rotating shaft passes upward through a bearing on the fixed retrieval plate 4 and connects to the output shaft of the retrieval motor. Through holes 6 are arranged in a ring array along the rotation axis of the movable retrieval plate 5 on both the fixed retrieval plate 4 and the movable retrieval plate 5. The solid area between two adjacent through holes 6 on the movable retrieval plate 5 is larger than the area of ​​the corresponding through hole 6 on the fixed retrieval plate 4. This is to ensure that there are no gaps in the foam retrieval part 3 when the positions of the through holes 6 on the fixed retrieval plate 4 and the movable retrieval plate 5 are staggered. Furthermore, a downwardly protruding arc-shaped part 23 is provided at the lower end of the solid area between two adjacent through holes on the movable retrieval plate 5.

[0023] A ring of fixed baffles 13 is provided on the outer wall of the fixed retrieval plate 4. The outer diameter of the fixed baffles 13 is adapted to the inner diameter of the primary cooking pot 1, and the upper end face of the fixed baffles 13 is higher than the upper end face of the fixed retrieval plate 4. When the fixed retrieval plate 4 is submerged below the liquid surface of the primary cooking pot 1, the outer wall of the fixed baffles 13 is in contact with or close to the inner wall of the primary cooking pot 1.

[0024] Specific working process: Place the washed and chopped beef into the initial cooking pot 1, then pour in cold water, ensuring the water level is above the beef. Add cooking wine as needed. Place the initial cooking pot 1 below the scum removal section 3. At this point, the fixed scum removal plate 4, the movable scum removal plate 5, and the initial cooking pot 1 are concentrically positioned. Then, the lifting platform 2 moves upward under the push of the hydraulic cylinder, etc. During the upward movement of the initial cooking pot, the upper surface of the fixed scum removal plate 4 sinks below the liquid surface in the initial cooking pot 1. At this time, the scum removal motor, etc., is on the liquid surface, and the through holes 6 on the fixed scum removal plate 4 and the movable scum removal plate 5 are aligned, allowing the liquid in the initial cooking pot 1 to flow above the fixed scum removal plate 4.

[0025] The heating device is then turned on to heat the initial cooking pot 1, thereby carrying out the initial cooking. The foam generated during the initial cooking process flows to the top of the fixed skimming plate 4.

[0026] After the initial boiling is completed, the movable skimming plate 5 begins to rotate, so that the positions of the through holes 6 on the fixed skimming plate 4 and the movable skimming plate 5 are misaligned. At this time, the foam skimming part 3 separates the liquid in the initial boiling pot 1. Then the initial boiling pot is lowered with the lifting platform 2 until the lower end of the foam skimming part 3 is higher than the upper end of the initial boiling pot 1, thereby quickly removing the foam in the initial boiling pot 1.

[0027] Example 2, as Figure 1 As shown, other structures and working processes in this embodiment can be referred to in Embodiment 1. However, in order to further improve the level of automation, the foam removal device in this embodiment also includes a transverse moving seat 7 that moves laterally. In order to drive the transverse moving seat 7 to move, existing technologies such as hydraulic cylinders can be used to push it. In this embodiment, the transverse moving seat 7 is provided with extensions on both sides. One side extension is provided on the guide post, and the other side extension is threadedly connected to the lead screw. One end of the lead screw is connected to the drive motor. The transverse moving seat 7 is connected to the foam retrieval part 3 through the bracket 8. The bracket 8 includes a column whose lower end is connected to the fixed retrieval plate 4 or the fixed baffle 13. The upper end of the column is connected to the crossbeam. The retrieval motor is provided on the crossbeam. The crossbeam is connected to the transverse moving seat 7 through the connecting part. A cleaning tank 9 is provided below the moving path of the transverse moving seat 7. A nozzle 10 facing the inside of the cleaning tank 9 is provided above the cleaning tank 9.

[0028] The nozzle 10 is mounted on the water pipe 11. The lower part of the water pipe 11 is connected to the rotary joint 12 on the bottom wall of the cleaning tank 9 via a transverse connecting pipe. The rotary joint 12 is connected to the water source and is located on the axis of the cleaning tank 9. A transmission gear is mounted on the side wall of the water pipe 11. The transmission gear meshes with the drive gear. The drive gear is located on the output shaft of the cleaning motor. The cleaning motor is mounted on the outer wall of the cleaning tank 9.

[0029] Specific working process: After the foam removal part 3 is removed from the primary cooking pot 1, the horizontal moving seat 7 moves the foam removal part 3 upwards to the cleaning tank 9. After the movement is completed, the nozzle 10 sprays hot water and other cleaning liquid onto the foam removal part 3. To avoid water spillage, the cleaning tank 9 can be installed on a vertical moving platform. When the foam removal part 3 moves between the cleaning tank 9 and the nozzle 10, the cleaning tank 9 rises, allowing the foam removal part 3 to enter the cleaning tank 9. During the cleaning process, the movable scooping plate 5 rotates periodically or irregularly so that the liquid on the foam removal part 3 flows into the cleaning tank 9 through the through hole 6. During the cleaning process, the nozzle 10 rotates with the water pipe to improve the cleaning effect.

[0030] Example 3, as Figure 2-3As shown, other structures and working processes in this embodiment can be referred to in Embodiment 1. However, in this embodiment, in order to prevent the foam from falling out during the movement of the foam retrieval part 3, the fixed baffle 13 is provided with a ring of concentric insertion holes. The upper part of the inner wall of the ring insertion hole is provided with a stop part 15. The lower part of the movable baffle 14 extends into the ring insertion hole, and the lower end of the movable baffle 14 is provided with a limiting part 16 whose outer diameter is larger than the inner diameter of the stop part 15. In this embodiment, the lower end of the column in the bracket 8 is connected to the upper end of the movable baffle 14 that extends out of the fixed baffle 13. The movable baffle 14 is ring-shaped and coaxially arranged with the fixed baffle 13. Since the movable retrieval plate 5 in the foam retrieval part 3 will rotate, in order to ensure the stability of the movement of the movable baffle, the outer wall of the movable baffle and the inner wall of the fixed baffle are fitted with a keyway. The outer diameter of the movable retrieval plate 5 is smaller than the outer diameter of the fixed baffle 13. The inner wall of the initial cooking pot 1 is provided with a positioning part 17.

[0031] The specific working process is as follows: The initial boiling pot 1 moves upward until the lower end face of the fixed baffle 13 contacts the upper end face of the positioning part 17. Then, the positioning part 17 pushes the fixed baffle 13 to continue rising, while the position of the movable baffle remains unchanged, causing the overall height of the movable baffle 14 and the fixed baffle 13 to decrease. At this time, the liquid level in the initial boiling pot 1 can be higher than the movable baffle 14. After the initial boiling is completed, the initial boiling pot 1 descends. The fixed baffle 13 loses the support of the positioning part 17, so the fixed baffle 13 descends due to gravity, causing the overall height of the movable baffle 14 and the fixed baffle 13 to increase. At this time, the liquid level above the foam removal part 3 is lower than the upper end face of the movable baffle 14, thereby ensuring that the foam removal part 3 will not spill out.

[0032] Example 4, as Figure 1 As shown, other structures and working processes of this embodiment can be referred to in Embodiment 1, but in this embodiment it also includes a heating tank 18 for heating the initial cooking pot 1. The heating tank 18 is placed on the upper end of the lifting platform 2. The upper end of the heating tank 18 is open. Heating devices such as electric heating tubes are installed inside the heating tank 18.

[0033] The bottom of the initial cooking pot 1 is provided with a through hole concentric with it. The through hole is connected to the rotating part 19 through bearings, shaft seals, etc. A stirring rod 20 is provided on the outer wall of the rotating part 19. The lower end of the rotating part 19 is open. A transmission key is provided on the inner wall of the rotating part 19. A transmission shaft 22 driven by a stirring motor 21 is provided on the heating tank 18. The stirring motor 21 is located on the outside of the heating tank 18. The upper end of the transmission shaft 22 extends into the heating tank 18, and an active key is provided on the outer wall of this part.

[0034] Specific working process: When the foam removal unit 3 is not above the heating tank 18, the production personnel hoist the initial cooking pot 1 into the heating tank 18. During hoisting, it is necessary to ensure that the drive shaft 22 is inserted into the rotating part 19 from below. After hoisting is completed and initial cooking is carried out, the drive shaft 22 rotates under the drive of the stirring motor 21. During the rotation, the side of the active key contacts the drive key, thereby driving the rotating part 19 to rotate. As the rotating part 19 rotates, the stirring rod 20 can turn the objects in the initial cooking pot 1.
