Description

Technical Field

[0001] This invention relates to the field of food processing equipment, specifically to a fully automatic braising production equipment. Background Technology

[0002] Currently, braised ingredients (duck, fish, and their meat products) need to be braised. Braised duck and braised fish are currently braised after being deep-fried or dried. After braising, they are dried again. The current braising process mainly involves pouring braising liquid into a braising pot, placing a strainer in the pot, and then placing the ingredients to be braised into the pot. After braising, the braised ingredients need to be removed from the pot and dehydrated and dried. The placement and removal of the braised foods all require manual operation by staff. Because the braising method is used, the working environment is hot, the labor intensity of the staff is high, and the time interval between two braising processes is long.

[0003] Current braising equipment mainly consists of a lifting and rotating basket placed inside the braising pot, where ducks or fish are placed for quick unloading and loading. However, all of these devices require staff to operate them near the braising pot, which increases labor costs. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this invention proposes a fully automatic braising production equipment, which facilitates the automatic braising of ingredients without manual operation, thus achieving high braising efficiency.

[0005] To achieve the above objectives, the present invention provides a fully automatic braising production equipment, comprising a braising pot, a rotating frame, a filling hopper, and a switching mechanism. The rotating frame is installed inside the braising pot and is driven by a stepper motor. Multiple cavities arranged in a circular array are formed on the rotating frame. A filling hopper, which is a porous groove, is inserted into each cavity. A porous mesh plate covers the outer circumference of the rotating frame. Switching mechanisms are located at both ends of the braising pot. The filling hopper is placed on the switching mechanisms, and a tilting assembly is installed on the switching mechanisms. A conveyor belt is located below the switching mechanisms to transport the ingredients.

[0006] The rotating frame includes a rotating shaft, a ring frame, and partition rods. The rotating shaft is mounted on the braising pot via bearings and bearing seats. The rotating frame consists of multiple ring frames arranged side by side, with the ring frames fitted onto the rotating shaft. The rotating shaft and the ring frames are connected by partition rods arranged in a ring array. The cavity formed between adjacent partition rods is used to place the filling hopper. The partition rods fit against the outer wall of the filling hopper. The top of the filling hopper is covered by a perforated mesh plate, thus forming a braising space for placing ingredients.

[0007] The switching mechanism includes a placement frame and a tilting assembly. Placement frames are provided at both ends of the rotating shaft. Pushing assemblies are installed on the placement frames to push the filling hoppers. The placement frames are rotatably connected to the ground through bearings and bearing seats. Clamping assemblies for clamping the filling troughs are installed on the placement frames. The placement frames are driven to rotate by the tilting assembly. A conveying track is provided on one side of the braising pot to convey the filling hoppers on the two placement frames.

[0008] Preferably, a groove is formed on the outer wall of the filling hopper, and an embedding groove is formed on the top of the placement frame for the filling hopper to be embedded in. A clamping component, which is a guide rail, is installed in the embedding groove. The guide rail is inserted into the grooves on both sides of the outer wall of the filling hopper. A water collection trough is set at the bottom of the embedding groove. The water collection trough is connected to the filling hopper through multiple holes and is connected to a negative pressure pipe. The brine in the filling hopper is pumped away by negative pressure. A swing frame is installed on the rotating placement frame. A first hydraulic cylinder is hinged between the swing frame and the ground. The first hydraulic cylinder realizes the 90° swing of the placement frame. A linear guide rail is set on one side of the placement frame and the conveying track. A slider is clamped on the linear guide rail. The slider slides on the linear guide rail. A chain driven by a sprocket is installed on the back of the linear guide rail. The slider is fixed to the chain. The chain drives the slider to move. Baffles are installed on both sides of the slider facing the filling hopper. The baffles push the filling hopper to move horizontally. This realizes the horizontal movement of the filling hopper on the two placement frames.

[0009] Preferably, an inclined plate is provided on the ground on one side of one of the placement racks. When the placement rack rotates 90°, the filling hopper is located directly above one end of the inclined plate. Two flow-limiting plates inclined towards the middle are provided on the top surface of the inclined plate. A column and a reciprocating assembly are installed on the ground below the inclined plate. The column is installed on the ground, and the lower part of the inclined plate near the filling hopper is hinged to the column. A reciprocating assembly is provided below the other end of the inclined plate. The reciprocating assembly includes a drive shaft, an eccentric wheel, and a collar. The drive shaft is installed on the ground through a bearing and a bearing seat. The drive shaft is driven by a motor. An eccentric wheel is installed on the drive shaft, and a collar is fitted on the eccentric wheel. A connecting rod is provided between the outer wall of the collar and the bottom of the inclined plate. The connecting rod is hinged to the collar and the inclined plate respectively.

[0010] Preferably, a temporary storage hopper is provided above one of the placement racks, and a feeding assembly is provided above the temporary storage hopper to transport the food into the hopper. A lifting assembly is provided on the temporary storage hopper, and a discharge port is provided at the bottom of the hopper. A valve linked to the lifting assembly is provided at the discharge port; when the lifting assembly lowers the temporary storage hopper, the valve at the discharge port opens. A gantry frame is provided on the ground, and the temporary storage hopper is located below the gantry frame. A lifting assembly is provided between the gantry frame and the temporary storage hopper, thus raising and lowering the temporary storage hopper through the lifting assembly. The valve includes a sealing cloth, a sliding plate, and a guide groove. Guide grooves are opened at both ends of the discharge port, and sliding plates are inserted into the guide grooves. A hinge is provided at the top of the two sliding plates. The pull rod has an oblong hole on the end face of the temporary storage hopper, into which a sliding column that moves up and down is embedded. The other end of the pull rod is fitted onto the sliding column, and a spring is embedded in the oblong hole. The spring pushes the sliding column upward. A rotating shaft is installed on the outer walls of both sides of the temporary storage hopper via bearings. The rotating shaft is connected to the slide plate with a sealing cloth. A gear is installed at one end of the rotating shaft, and a rack that meshes with the gear is installed on one side of the gear. The rack slides in contact with the temporary storage hopper. A lifting pulley is installed at the bottom of the rack. A return spring is installed between the rack and the temporary storage hopper. The rack descends through the return spring. The tops of the two racks are connected by a flat plate, on which a pin is installed. A pin hole is opened on the slide plate for the pin to be inserted.

[0011] Compared with the prior art, the advantages of the present invention are: it facilitates the automatic braising of ingredients without manual operation, thus achieving high braising efficiency. Attached Figure Description

[0028] The invention will now be further described with reference to the accompanying drawings.

[0029] like Figure 1-15The aforementioned fully automatic braising production equipment includes a braising pot 1, a rotating frame 2, a filling hopper 7, and a switching mechanism 12. The braising pot 1 is semi-cylindrical, with both ends sealed by sealing plates. The rotating frame 2 is installed inside the braising pot 1, with both ends mounted via bearings and bearing seats, allowing the rotating frame 2 to rotate within the braising pot 1. The rotating frame 2 is driven by a stepper motor, which is bolted to the end face of the braising pot 1. A transmission system connects the stepper motor and the rotating frame 2, enabling the rotation of the rotating frame 2. The rotating frame 2 has multiple cavities 6 arranged in a circular array. A filling hopper 7 is inserted into each cavity 6. The filling hopper 7 is a porous groove 10, with both ends sealed. Ingredients to be braised are placed in the filling hopper 7. The rotating frame 2 immerses the ingredients in the filling hopper 7 into the braising pot 1 for braising. After braising, the rotating frame 2 raises the filling hopper 7. The braising liquid is separated from the braising pot 1 and drained through the porous structure of the filling hopper 7. A porous mesh plate 11 is welded onto the outer circumference of the rotating frame 2 to seal the top of the filling hopper 7, thus preventing the food from falling out. Switching mechanisms 12 are provided at both ends of the braising pot 1. When the filling hopper 7 on the rotating frame 2 rotates to the highest position, it can be transferred from the rotating frame 2 to the switching mechanism 12. The filling hopper 7 is placed on the switching mechanism 12, and a tilting component 17 is installed on the switching mechanism 12. The food in the filling hopper 7 after braising is emptied by the tilting component 17. A conveyor belt 27 is provided below the switching mechanism 12. The emptied food is poured onto the conveyor belt 27 and transported away by the conveyor belt 27. Then, the filling hopper 7 is filled with food and placed into the rotating frame 2 for braising again.

[0030] The rotating frame 2 includes a rotating shaft 3, annular frames 4, and spacers 5. The rotating shaft 3 is mounted on the top surfaces of both ends of the braising pot 1 via bearings and bearing seats. A drive sprocket is welded to one end of the rotating frame 2, and a drive sprocket is also welded to the output shaft of the stepper motor on the braising pot 1. A drive chain 24 is provided between the two drive sprockets, and the drive chain 24 meshes with the two drive sprockets, thus driving the rotating shaft 3 to rotate. The rotating frame 2 consists of multiple annular frames 4 arranged side by side, coaxial with the rotating shaft 3. The annular frames 4 are fitted onto the rotating shaft 3, and spacers 5 are arranged in a ring array between the rotating shaft 3 and the annular frames 4. The rods 5 are connected (multiple rows of partition rods 5 are fixed to the rotating shaft 3 by welding, and multiple partition rods 5 on each row are fixed to the rotating shaft 3 in a ring array. The other end of each partition rod 5 is fixed to the ring frame 4, so that the rotating shaft 3 and the ring frame 4 are fixed). The cavity 6 formed between adjacent partition rods 5 is used to place the filling hopper 7. The partition rods 5 clamp the two sides of the filling hopper 7, and at the same time, the ring frame 4 presses the top of the filling hopper 7. In this way, the filling hopper 7 can only slide along the partition rods 5. The partition rods 5 are in contact with the outer wall of the filling hopper 7. The top of the hopper is covered by a perforated mesh plate 11, thus forming a braising space for placing ingredients.

[0031] The switching mechanism 12 includes a placement rack 13 and a tilting assembly 17. The placement rack 13 is located at both ends of the rotating shaft 3 and is positioned on both ends of the braising pot 1. A pushing assembly 58 (e.g., ...) is installed on one side of the placement rack 13. Figure 1As shown, the pushing assembly 58 is mounted on the left placement frame 13. The pushing assembly 57 is a hydraulic cylinder (the cylinder body of the pushing assembly 58 is bolted to the left side of the left placement frame 13). The pushing assembly 58 pushes the filling hopper 7 to the right. The placement frame 13 is rotatably connected to the ground through bearings and bearing seats, allowing it to rotate. The axis of rotation of the placement frame 13 is coaxial with the rotation axis 3. A clamping assembly 15 is installed on the placement frame 13 to clamp the filling hopper 7. When the filling hopper 7 moves onto the placement frame 13, the clamping assembly 15 clamps the filling hopper 7 to prevent it from separating from the placement frame 13 when it rotates. The placement frame 13 is driven to rotate 90° by the tilting assembly 17. A conveying track 26 parallel to the rotation axis 3 is fixed to one side of the braising pot 1 by bolts. When the two placement frames 13 rotate 90°, the two placement frames 13 and the conveying track 26 are clamped together. The track 26 is connected, and the filling hopper 7 on one set of placement racks 13, after emptying the food, moves to the conveying track 26. Then, the filling hopper 7 on the conveying track 26 is conveyed to another set of placement racks 13, thus realizing the switching of the filling hopper 7. The filling hopper 7 on the two placement racks 13 is conveyed through the conveying track 26. When working, the filling hopper 7 is placed on the left placement platform, and food is placed in the filling hopper 7. At the same time, the pushing component 58 pushes the filling hopper 7 on the left placement rack 13 to the right. In this way, the filling hopper 7 on the placement rack 13 pushes the filling hopper 7 on the top of the rotating frame 2 out. The filling hopper 7 pushed out from the rotating frame 2 moves to the right placement rack 13. After the food in the filling hopper 7 is emptied by the tilting component 17 on the placement rack 13, the filling hopper 7 on the right placement rack 13 is conveyed to the left placement rack 13 through the conveying track 26. Then, the placement rack 13 rotates 90° in the opposite direction to return to its original position to load food.

[0032] A longitudinally arranged groove 8 is formed on the outer wall of the filling hopper 7. An embedding groove 9 is formed on the top of the placement frame 13 for the filling hopper 7 to be inserted into. The filling hopper 7 slides into the embedding groove 9. A clamping assembly 15, which is also a guide rail 16, is installed in the embedding groove 9. The guide rail 16 is engaged with the grooves 8 on both sides of the outer wall of the filling hopper 7, thus restricting the degree of freedom of the filling hopper 7. The filling hopper 7 can only move along the embedding groove 9 on the placement frame 13. Multiple water collection grooves 18 are formed at the bottom of the embedding groove 9. The water collection grooves 18 are connected to the filling hopper 7 through multiple holes. The multiple water collection grooves 18 are connected to a negative pressure pipe 19, which is connected to a negative pressure pump. The brine in the filling hopper 7 is quickly pumped away through negative pressure. A tilting assembly is also included. 17 includes a swing frame 20 and a first hydraulic cylinder 21. The swing frame 20 is mounted on the placement frame 13 and is fixed to the bottom surface of the placement frame 13 by bolts. A shaft is mounted on the ground via bearings and bearing seats. A through hole is opened below the swing frame 20 to fit the shaft. The shaft passes through the through hole of the swing frame 20 and is welded to the swing frame 20. The swing frame 20 rotates synchronously with the shaft. The first hydraulic cylinder 21 is hinged between the swing frame 20 and the ground. The 90° swing of the placement frame 13 is achieved by the extension and retraction of the first hydraulic cylinder 21. When the placement frame 13 needs to be docked with the rotating frame 2, the first hydraulic cylinder 21 retracts. When the placement frame 13 needs to be docked with the conveyor track 26, the first hydraulic cylinder 21 retracts. During docking, the first hydraulic cylinder 21 lifts the frame, causing the placement frame 13 to rotate 90° and dock with the conveyor track 26. A linear guide rail 22 is bolted to the ground in front of the placement frame 13 and the conveyor track 26. The linear guide rail 22 is mounted on the ground via support legs. A slider 23, which moves left and right on the linear guide rail 22, is mounted on the linear guide rail 22. A chain 24, driven by a sprocket, is mounted on the back of the linear guide rail 22. The slider 23 and the chain 24 are fixed together with bolts. Motor-driven sprockets are mounted on the top surfaces of the linear guide rail 22 at both ends via bearings. The chain 24 is fitted onto the two sprockets, and the sprockets drive the chain 24 to move. The motor moves the slider 23 via the chain 24. Baffles 25 are bolted to both ends of the slider 23 facing the filling hopper 7. The baffles 25 push the filling hopper 7 to move horizontally (when the filling hopper 7 rotates 90 degrees and connects with the conveying track 26, the baffles 25 press against the right end of the filling hopper 7, and the chain 24 drives the filling hopper 7 to move to the left. The filling hopper 7 moves from the right placement frame 13 to the left placement frame 13. Then the motor reverses, and the baffles 25 move to the right to return to their original position, which facilitates the movement of the next filling hopper 7). This allows the filling hopper 7 to move horizontally on the two placement frames 13, thus achieving the switching of the filling hopper 7.

[0033] A baffle 25 extending upwards is bolted to the right end of the right-side placement frame 13. A vertical groove is cut into the baffle 25, and a slide block that moves vertically up and down is mounted on the groove. A cylinder is bolted between the slide block and the groove, and the cylinder raises and lowers the slide block. A second hydraulic cylinder is bolted to the slide block, and a pull plate 57 is bolted to the piston of the second hydraulic cylinder. The pull plate 57 moves the loading hopper 7 to the right and aligns it with the baffle 25. 5. The baffle 25 is positioned to allow the filling hopper 7 to move closer together via the sliding seat lifting mechanism. An inclined plate 28 is installed on the ground on the front side of the right-side placement frame 13. When the placement frame 13 rotates 90°, the filling hopper 7 is positioned directly above one end of the inclined plate 28. Two flow-limiting plates 29 inclined towards the center are installed on the top surface of the inclined plate 28. A column 30 and a reciprocating assembly 31 are installed on the ground below the inclined plate 28. Columns 30 are bolted to the ground on the left and right sides of the inclined plate 28, below the end of the inclined plate 28 closest to the filling hopper 7. Hinged to the column 30, the inclined plate 28 can swing up and down. A reciprocating assembly 31 is located below the other end of the inclined plate 28. The reciprocating assembly 31 includes a drive shaft 32, an eccentric wheel 33, and a collar 34. The drive shaft 32 is mounted on the ground via bearings and bearing seats. The drive shaft 32 is fixed to the motor output shaft by welding for driving. The eccentric wheel 33 is welded onto the drive shaft 32, and a collar 34 is fitted onto the eccentric wheel 33. The collar 34 rotates on the eccentric wheel 33. A connecting rod 35 is provided between the outer wall of the ring 34 and the bottom of the inclined plate 28. The two ends of the connecting rod 35 are hinged to the ring 34 and the inclined plate 28 respectively. During operation, the motor drives the drive shaft 32 to rotate, and the drive shaft 32 drives the eccentric wheel 33 to rotate. In this way, the ring 34 drives the end of the inclined plate 28 away from the column 30 to swing up and down, forming a reciprocating swing. This unloading is achieved by bumping. During the bumping, the food is dispersed and prevented from sticking together.

[0034] A temporary storage hopper 36 is installed above a set of placement racks 13 on the left side. Above the temporary storage hopper 36 is a feeding assembly 37 (the feeding assembly 37 is a roller-driven feeding belt, which is fitted onto two rollers driven by a motor; the food is placed on the feeding belt for transport). The feeding assembly 37 transports the food into the temporary storage hopper 36, which is located directly below one end of the feeding assembly 37. The food transported by the feeding assembly 37 falls into the temporary storage hopper 36. A lifting assembly 38 is installed on the temporary storage hopper 36 to raise and lower it. A rectangular discharge port 39 is opened at the bottom of the temporary storage hopper 36, and a valve 40 linked to the lifting assembly 38 is installed at the discharge port 39. When the lifting assembly 38 lowers the temporary storage hopper 36... When the discharge port 39 is raised, the valve 40 opens, and the food in the temporary storage hopper 36 is discharged into the loading hopper 7 on the left. When the temporary storage hopper 36 rises, the valve 40 closes, stopping the discharge, and then loading begins. When the temporary storage hopper 36 descends, the feeding assembly 37 is de-energized and stops the discharge. A gantry frame 56 is installed on the ground by bolts. The temporary storage hopper 36 is located below the gantry frame 56. A lifting assembly 38 is installed between the gantry frame 56 and the temporary storage hopper 36. The lifting assembly 38 is a hydraulic cylinder. The lifting of the temporary storage hopper 36 is achieved by the lifting of the hydraulic cylinder. The valve 40 includes a sealing cloth 41, a sliding plate 42, and a guide groove 38. Horizontal guide grooves 38 are opened on the walls at both ends of the discharge port 39 (e.g., ...). Figure 14As shown, a sliding plate 42 is inserted into the guide groove 38. Both ends of the sliding plate 42 extend into the guide grooves at the left and right ends for sliding. Pull rods 45 are hinged to the top of both ends of the two sliding plates 42. Vertically arranged oblong holes are opened on the outer walls of the front and rear ends of the temporary storage hopper 36. A sliding column 46, which moves up and down within the oblong hole, is embedded in the oblong hole. The other end of each pull rod 45 has a through hole and is fitted onto the sliding column 46. The pull rods 45 are pulled up and down by the sliding column 46. A spring 47 is embedded in the oblong hole, located at the bottom of the sliding column 46. The bottom of the spring 47 abuts against the bottom of the oblong hole, and the top of the spring 47 abuts against the top of the oblong hole. The spring 47 pushes the sliding column 46 upwards. When the sliding column 46 descends... Pull rod 45 pushes slide plate 42 forward and backward to both sides, thus opening valve 40. When slide column 46 is not under pressure, slide column 46 rises under the action of spring 47, thus pulling pull rod 45 to close slide plate 42, thus closing valve 40 and stopping material feeding. Rotary shafts 48 are installed on the outer walls of both sides of temporary storage hopper 36 via bearings. Rotary shafts 48 are connected to slide plate 42 by sealing cloth 41. Slide plate 42 is fixed to slide plate 42 and rotating shaft 48 by rivets. When slide plate 42 is closed, sealing cloth 41 on rotating shaft 48 is unrolled. Gear 49 is installed at one end of rotating shaft 48 by welding. A rack 50 meshing with gear 49 is installed on one side of gear 49. The rack 50 is connected to temporary storage hopper 36. A sliding fit is used. A vertical rack 50 is bolted to the left end face of the temporary storage hopper 36. The rack 50 moves up and down on the temporary storage hopper 36. A lifting pulley 51 is installed at the bottom of the rack 50 via a bearing. A return spring 52 is welded between the rack 50 and the temporary storage hopper 36. The rack 50 descends via the return spring 52. When the temporary storage hopper 36 descends, the pulley 51 at the bottom of the rack 50 presses against the top surface of the filling hopper 7, thus opening the valve 40. The food in the temporary storage hopper 36 is fed into the filling hopper 7. When the push assembly 58 pushes the filling hopper 7 to the right, the filling hopper 7 is filled with food as it moves. When the filling hopper 7 and the rack 50 are misaligned, the rack 50 descends, and the rotating shaft 4... 8. Unwinding: The two slide plates 42 move towards the center and close together, thus closing the valve 40. The tops of the two racks 50 are connected by a plate 53. The two ends of the plate 53 are fixed to the two racks 50 by bolts. The bottom of the plate 53 is fitted with a pin 54 by welding. A pin hole 55 is opened at the top of the end of the slide plate 42 that protrudes from the temporary storage hopper 36 for the pin 54 to be inserted. When the racks 50 descend, the slide plates 42 move towards the center and close together, so that the pin 54 is inserted into the pin hole 55, thus locking the slide plate 42. The rack 50 has no teeth near the top. When the rack 50 descends to the position where there are no teeth and is opposite the gear 49, the rack 50 will not drive the rotating shaft 48 to rotate as it continues to descend.
