Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a conveying device and conveying method for food processing. Background Technology

[0002] Food processing involves altering the flavor of raw or semi-finished food products through various processing methods. During different processing steps, a conveyor platform is used to transfer food from one process to the next, and during the transfer process, heat-treated food is cooled down. In the cooling process of cooked food processing and baking, belt cooling conveyors are generally used as the core cooling equipment. This equipment uses a continuously circulating conveyor belt to quickly and evenly cool high-temperature cooked food or baked products to near room temperature within 20 to 40 minutes. This efficient cooling method can effectively prevent food from staying in a high-temperature environment for a long time, thereby significantly inhibiting the rapid reproduction of microorganisms and achieving the important purpose of extending the shelf life of food and maintaining the flavor and safety of products. However, in the cooling process of food processing, the cooling conveyors currently in use are relatively simple in function and cooling method. They can only cool the surface of the food evenly, which can easily lead to the phenomenon that the temperature on one side of the food has reached the cooling standard while the other side still remains at a higher temperature. This results in uneven cooling of the food as a whole, affecting the final cooling effect and food quality. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a conveying device and conveying method for food processing. By setting a flipping unit, food can be automatically flipped. This function not only speeds up the cooling of food but also avoids the problem of poor cooling effect caused by one-sided cooling or uneven cooling, thus preventing the food processing cycle from being prolonged due to low cooling efficiency.

[0004] To solve the above-mentioned technical problems, the present invention provides a solution to address the issue that cooling only the surface of food can result in uneven cooling, where one side of the food reaches the cooling standard while the other side remains at a high temperature, thus affecting the cooling effect and food quality.

The material carrier plate b extends to one side of the conveyor belt c, and a material distribution plate is fixed on the material carrier plate b.

[0014] Preferably, a conveying method for food processing includes the following steps: S1. Food feeding process: First, the operator must accurately pour the various food materials to be cooled into the feeding hopper to ensure that the feeding process is stable and orderly and to avoid spillage or uneven accumulation of materials. S2. Food transfer operation: The operation of conveyor belt a is controlled by the transfer unit, and at the same time, the turning plate b is driven to rotate at a constant speed. The turning plate b, through regular turning action, makes the food in the feed hopper evenly dispersed and fall smoothly onto the surface of conveyor belt a, and the conveyor belt a realizes the initial horizontal transfer of food. S3, Initial cooling stage of food: The cooling fan a set above the conveyor belt starts to start, generating a continuous and stable forced convection airflow. This airflow directly acts on the food being transported on the surface of the conveyor belt a, and achieves the initial cooling treatment of the food surface through the principle of convection heat transfer. S4. Food sorting and arrangement process: With the structural guidance of the sorting plate, the food is automatically adjusted to a neat straight line after being subjected to directional mechanical force during the transmission process. Then the food is orderly transferred to the carrier plate a, smoothly transitioned to the conveyor belt c through moderate squeezing, and continues to be stably transported to the turning unit through the conveyor belt c. S5. Food flipping process: When the food arrives at the flipping unit, the unit flips the food 180 degrees to ensure that both sides of the food are processed. After flipping, the food falls accurately onto the conveyor belt c for continued transport. When it reaches the distribution plate, the distribution plate guides the food to the conveyor belt b in sequence through the diversion and guiding structure. S6. Secondary cooling of food: The cooling fan b located above conveyor belts b and c starts to work, generating a wide-area cooling airflow, and at the same time, uniformly and intensely cooling the food on conveyor belts b and c to ensure a more thorough cooling effect. S7. Food feeding and conveying stage: When the food runs to the end position with the conveyor belt b, it falls naturally into the hopper below under the action of gravity. It then slides smoothly onto the surface of the conveyor belt d through the inclined structure inside the hopper, and the conveyor belt d continues to carry out the next stage of horizontal conveying operation. S8. Three-stage cooling process for food: The set cooling fan c starts to run, generating cooling airflow to perform a final stage of deep cooling process on the food conveyed on the conveyor belt d, ensuring that the food reaches the predetermined temperature requirements. S9. Food material collection process: After all the cooling treatment is completed, the food is transported to the end hopper by the conveyor belt d. The operator can select a suitable container according to the production needs to collect and store the final product in a standardized manner.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a conveying device and conveying method for food processing. By setting up a flipping unit, food can be automatically flipped. This function not only significantly speeds up the cooling of food, but also effectively avoids the problem of poor cooling effect caused by one-sided cooling or uneven cooling of food, thereby preventing the extension of the overall food processing and handling time cycle due to low cooling efficiency.

[0016] This invention provides a conveying device and method for food processing. Through the installation of a cooling unit, a cooling fan a performs a first-stage initial cooling treatment on the food on conveyor belt a, effectively reducing the surface temperature of the food. Then, a cooling fan b performs a second-stage secondary cooling treatment on the food on conveyor belts b and c, further uniformly dissipating heat and improving the cooling effect. When the food finally falls onto conveyor belt d, a third-stage deep cooling treatment is performed on the food on conveyor belt d by cooling fan c. This achieves multi-level, multi-stage, and highly efficient multiple cooling treatments for the food, ensuring food quality and safety. Attached Figure Description

[0024] Example 1: Please refer to Figures 1-13 A conveying device for food processing includes a frame a1 and a frame b2, and further includes: a feeding hopper 3 fixed on the frame a1, and a conveying unit 4 provided on the frame a1 for conveying and moving food; a cooling unit 5 provided on the frame a1 and the frame b2 for cooling the food; and a flipping unit 6 provided on the frame b2 for flipping the food. A conveying method for food processing includes the following steps: S1. Food feeding process: First, the operator must accurately pour the various food materials to be cooled into the feeding hopper 3 to ensure that the feeding process is stable and orderly and to avoid spillage or uneven accumulation of materials. S2. Food transfer operation: The operation of the conveyor belt a8 is controlled by the transfer unit 4, and the flipping plate b42 is driven to rotate at a constant speed. The flipping plate b42, through regular flipping action, makes the food in the feed hopper 3 evenly dispersed and fall smoothly onto the surface of the conveyor belt a8, and the conveyor belt a8 realizes the initial horizontal transfer of the food. S3, Initial cooling stage of food: The cooling fan a22 set above the conveyor belt starts to start, generating a continuous and stable forced convection airflow. This airflow directly acts on the food being transported on the surface of the conveyor belt a8, and achieves the initial cooling treatment of the food surface through the principle of convection heat transfer. S4. Food sorting and arrangement process: With the structural guidance of the sorting plate 28, the food is automatically adjusted to a neat line sequence after being subjected to directional mechanical force during the transmission process. Then the food is orderly transferred to the carrier plate a64, and smoothly transitioned to the conveyor belt c14 through moderate squeezing. It continues to be stably transported to the turning unit through the conveyor belt c14. S5. Food flipping process: When the food arrives at the flipping unit 6, the unit flips the food 180 degrees to ensure that both sides of the food are processed. After flipping, the food falls accurately onto the conveyor belt c14 for further transport. When it reaches the distribution plate 67, the distribution plate 67 guides the food to the conveyor belt b12 in sequence through the diversion and guiding structure. S6. Secondary cooling of food: The cooling fan b23 located above conveyor belts b12 and c14 starts to work, generating a wide-area cooling airflow, and at the same time, uniformly and intensely cooling the food on conveyor belts b12 and c14 to ensure a more thorough cooling effect. S7. Food feeding and conveying stage: When the food runs to the end position with the conveyor belt b12, it falls naturally into the hopper 49 below under the action of gravity. It slides smoothly onto the surface of the conveyor belt d47 through the inclined structure inside the hopper 49, and the conveyor belt d47 continues to carry out the next stage of horizontal conveying operation. S8. Three-stage cooling process for food: The cooling fan C25 is started and runs to generate cooling airflow, which performs the final stage of deep cooling on the food conveyed on the conveyor belt D47 to ensure that the food reaches the predetermined temperature requirements. S9. Food material collection process: After all the cooling treatment is completed, the food is transported by conveyor belt d47 to the end hopper 50. The operator can select a suitable container according to the production needs to collect and store the final product in a standardized manner.

[0025] Furthermore, the transmission unit 4 includes: at least two drive rollers a7 rotatably connected to the frame a1, and a conveyor belt a8 sleeved on the two drive rollers a7; a servo motor a9 fixed on the frame a1, the output shaft of the servo motor a9 being coaxially fixed with one of the drive rollers a7; a material-turning component 10 provided on the feed hopper 3, the material-turning component 10 being used to accelerate food feeding; at least two drive rollers b11 rotatably connected to the frame b2, and two conveyor belts b12 being sleeved on the two drive rollers b11; a drive roller c13 rotatably connected to the frame b2, and a conveyor belt c14 sleeved on the drive roller c13; the drive rollers a7 and c13 are driven by pulleys a15 and belts a16; two adjacent drive rollers c13 are driven by pulleys b17 and belts b18; one drive roller b11 and the adjacent drive roller c13 are driven by two spur gears a19 meshing. A feeding assembly 20 is installed on frame b2 for feeding food. An arc-shaped guard plate 63 is fixed on frame a1, located on one side of conveyor belt a8. A carrying plate a64 is fixed on the arc-shaped guard plate 63, with its other end extending to one side of conveyor belt c14. A baffle 65 is fixed on frame b2, and a carrying plate b66 is fixed on the baffle 65, extending to one side of conveyor belt c14. A separating plate 67 is fixed on the carrying plate b66, and the separating plate 67 is triangular in shape. The angled shape serves to guide the flow of food. The feeding assembly 20 includes: a transmission roller d46 rotatably connected to a support plate 24, and a conveyor belt d47 sleeved on the transmission roller d46; a drive motor b48 fixed to the support plate 24 via a base, and the output shaft of the drive motor b48 is coaxially fixed with one of the transmission rollers d46; a feeding hopper 49 fixed on the frame b2, the feeding hopper 49 being located diagonally below the conveyor belt a8 and extending above the conveyor belt d47; and a dropping hopper 50 fixed on the frame b2. The material turning component 10 includes: a rotating shaft 41 rotatably connected inside the feed hopper 3, a number of circumferentially distributed turning plates b42 fixed on the rotating shaft 41, the rotating shaft 41 and the transmission roller a7 being driven by a pulley c43 and a belt c44, and a cleaning component 45 adapted to the conveyor belt a8 being provided on the frame a1, which is used to clean the surface of the conveyor belt a8; It should be noted that the transmission unit 4 can stably transmit food, ensuring that the food to be cooled can be smoothly transmitted to the designated position for cooling. In conjunction with the flipping component 10, the food is evenly flipped onto the conveyor belt a8, avoiding food feeding blockage and ensuring that the food to be cooled falls onto the conveyor belt a8 at a uniform speed for cooling. The principle of food transport using transmission unit 4: Driven by servo motor a9, transmission roller a7 rotates efficiently, effectively driving conveyor belt a8 to start smooth operation, thus continuously transporting food along a predetermined path. Simultaneously, the transmission between pulley c43 and belt c44 enables rotating shaft 41 to rotate synchronously, which in turn drives tipping plate b42 to rotate at the same speed. This evenly and continuously distributes the food in hopper 49 onto the surface of conveyor belt a8, ensuring uniform distribution of food on conveyor belt a8 and stably transferring the food to be cooled onto carrier plate a64. This allows the food to be smoothly extruded and fed onto conveyor belt c14 in subsequent processes. During this process, the belt... The efficient transmission of pulley a15 and belt a16, combined with the coordinated transmission of pulley b17 and belt b18, enables conveyor belts a8 and c14 to operate in the same direction and synchronously, thus ensuring the continuity of food transport. In addition, through the meshing transmission of spur gear a19, the rotation direction of drive shaft 58b is opposite to that of drive shaft 58c, which in turn causes the operating direction of conveyor belt b12 to be opposite to that of conveyor belt c14. This causes the food to fall into the hopper 49. Driven by drive motor b48, drive roller d46 to rotate, driving conveyor belt d47 to operate. After cooling, the food falls into hopper 50 and is discharged, thus realizing the food transport operation.

[0026] Furthermore, the cooling unit 5 includes: a baffle plate 21 is fixed on both the frame a1 and the frame b2, a cooling fan a22 is fixed on the baffle plate 21 via a mounting plate, and a number of cooling fans b23 are fixed on the baffle plate 21 via a frame a30, a support plate 24 is fixed on the frame b31, and a number of cooling fans c25 are fixed on the support plate 24 via the frame b31; The baffle plate 21 has several rods 26 fixed on it, and a sliding sleeve 27 is slidably connected to the rods 26. A sorting plate 28 is fixed on the sliding sleeve 27, and a screw a29 is threadedly connected to the sliding sleeve 27. A rubber washer is rotatably connected to one end of the screw a29 near the rod 26. By adding the sliding sleeve 27, the screw a29 and the rubber washer, when the position of the sorting plate 28 needs to be adjusted, the screw a29 is loosened to release the restriction on the sorting plate 28. The position of the sorting plate 28 can then be adjusted according to the food specifications to transform the scattered and disordered food into a neat and orderly state. It should be noted that, through the setting of cooling unit 5, the cooling fan a22 performs the first stage of initial cooling treatment on the food on conveyor belt a8, effectively reducing the surface temperature of the food. Then, the cooling fan b23 performs the second stage of secondary cooling on the food on conveyor belts b12 and c14 respectively, further dissipating heat evenly and improving the cooling effect. When the food finally falls onto conveyor belt d47, the cooling fan c25 performs the third stage of deep cooling treatment on the food on conveyor belt d47. This achieves the purpose of multi-level, multi-stage, and highly efficient multiple cooling treatments for the food, ensuring food quality and safety.

[0027] Example 2: Please refer to Figures 7-12 This embodiment further explains the first embodiment, and the difference lies in the method of turning the food over.

[0028] Furthermore, the flipping unit 6 includes: at least two hollow shafts 32 rotatably connected on the frame b31, a plurality of flipping plates a34 fixed at one end of the hollow shafts 32 by threaded sleeves 33, a guide plate 35 that slides between two adjacent threaded sleeves 33, a groove 36 is provided on the flipping plate a34, and a connecting plate 37 is slidably connected in the groove 36, a drive motor a38 is fixed on the frame b2 by a bracket, the output shaft of the drive motor a38 is driven by the hollow shafts 32 by meshing with a spur gear b39, and an adjustment component 40 adapted to the flipping plate a34 is provided on the frame b2, the adjustment component 40 is used to adjust the spacing of the flipping plates a34; The adjustable spacing assembly 40 includes: at least two mounting plates 51 fixed on the frame b2, a bidirectional threaded rod a52 rotatably connected to the mounting plate 51, and the bidirectional threaded rod a52 threadedly connected to the threaded sleeve 33, a rotating wheel a53 fixed to one end of the bidirectional threaded rod a52, a spring 54 fixed on the connecting plate 37, and the other end of the spring 54 fixed to the groove 36, and a screw b55 threadedly connected to the frame b2 through a support plate, a toothed plate 56 slidably connected to the frame b2 fixed to one end of the screw b55, and the toothed plate 56 being adapted to the spur gear b39. Through the setting of the adjustable spacing assembly 40, the operator can accurately control the working distance between the flipping plates according to the actual needs of different food processing scenarios, thereby effectively adapting to the flipping operation requirements of various specifications of food, and ensuring that food of different sizes and shapes can achieve a uniform and thorough flipping effect during the processing. It should be noted that during the threaded transmission engagement between the bidirectional threaded rod a52 and the threaded sleeve 33, the mutual sliding guide plate 35 structure is used to effectively guide and precisely limit the threaded sleeve 33, thereby significantly enhancing the stability and reliability of the spacing between the flipping plates a34 during the adjustment process, and ensuring the smoothness and precision of the transmission process. It should also be noted that the flipping unit 6 enables automatic flipping of food. This function not only significantly speeds up the cooling of food, but also effectively avoids the problem of poor cooling effect caused by one-sided cooling or uneven cooling, thereby preventing the overall food processing and handling time cycle from being extended due to low cooling efficiency. The principle of food flipping operation using flipping unit 6 is as follows: Driven by drive motor a38, the hollow shaft 32 is rotated by the meshing transmission of spur gear b39, which in turn drives the flipping plate a34 and connecting plate 37 to rotate together, thereby flipping the food. After flipping, the food falls onto conveyor belt c14. The principle of adjusting the spacing of the flipping plate a34 using the adjusting component 40 is as follows: By rotating the screw b55, the toothed plate 56 is moved until it meshes with the spur gear b39. Then, the rotating wheel a53 is rotated, causing the bidirectional threaded rod a52 to rotate. Utilizing the threaded transmission between the bidirectional threaded rod a52 and the threaded sleeve 33, the flipping plate a34 is moved, thus completing the adjustment of the spacing of the flipping plate a34.

[0029] Furthermore, the cleaning assembly 45 includes: a brush roller 57 rotatably connected to the frame a1 via a rotating seat, and the brush roller 57 is in contact with the conveyor belt a8; a drive shaft 58 rotatably connected to the frame a1, and the drive shaft 58 and the brush roller 57 are driven by meshing spur gear c59; the drive shaft 58 and the drive roller a7 are driven by pulley d60 and belt d61; and a collection box 62 is slidably connected to the frame a1 via a support frame, and the collection box 62 is located directly below the brush roller 57. Specifically, by setting the cleaning component 45, the rotation direction of the brush roller 57 is completely opposite to that of the drive roller a7. Through the high-speed friction between the brush roller 57 and the surface of the conveyor belt a8, various impurities and dirt attached to the conveyor belt a8 are effectively removed, thereby achieving a highly efficient and thorough cleaning effect. The cleaned impurities fall naturally due to gravity and fall precisely into the collection box 62 located below. The collection box 62 collects and processes the fallen impurities, which not only ensures the cleanliness of the working environment but also greatly facilitates subsequent impurity collection and cleaning operations.
