The device includes a base with several supporting legs. A pair of side plates arranged front-to-back are fixedly connected to the upper side of each supporting leg. Each side plate has a through-hole on its inner side. Flexible transmission units are installed on both the left and right sides of the pair of side plates.

Description

Technical Field

[0001] This invention relates to the field of rice crust production technology, specifically to an automated oil-reducing and anti-breakage device for producing rice crusts. Background Technology

[0002] As a common fried snack, rice crackers undergo several processes in industrial production, including frying and shaping, oil removal, and packaging. Because the surface of the rice crackers is covered with a large amount of oil after frying and is crispy and easily broken, the oil removal process must effectively remove excess oil to reduce the greasiness of the product and extend its shelf life. It must also prevent the rice crackers from breaking or crumbling during oil removal and subsequent transportation to ensure a high yield of finished products. Currently, most rice cracker production equipment uses centrifugal or draining methods to remove surface oil through gravity draining or high-speed centrifugal separation.

[0003] However, the above-mentioned degreasing methods have obvious shortcomings: centrifugal degreasing equipment relies on centrifugal force generated by high-speed rotation to remove grease. During operation, the vibration is severe and the collision and friction between materials are intense. The rice crusts are squeezed against each other in the centrifugal basket and have rigid impacts with the metal wall, which easily leads to edge breakage and overall fragmentation, resulting in a high breakage rate. Drainage degreasing equipment relies solely on gravity to naturally drain grease, which has low degreasing efficiency and takes a long time. The grease on the surface of the rice crusts is not removed evenly, and local oil accumulation is easy to occur. Moreover, the rice crusts slide and collide on the rigid conveyor surface during the draining process, which can also cause damage. In addition, the above-mentioned equipment generally lacks automated means to adjust the degreasing parameters in real time according to the state of the rice crusts, making it difficult to meet the dual production requirements of efficient oil reduction and low loss and breakage prevention. This results in high production costs and difficulty in uniformly controlling product quality. Therefore, based on the above problems, an automated oil reduction and breakage prevention device for producing rice crusts is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an automated oil-reducing and anti-breakage device for producing rice crusts, in order to solve the problems of low oil removal efficiency and high breakage rate caused by severe vibration during operation of existing equipment.

The upper belt of the left flexible conveyor belt is located between the housing and the receiving shell. The right flexible conveyor section is set at an inclined angle, and the left end of the liquid guide plate is located below the right end of the right flexible conveyor section.

[0008] Preferably, the follow-up covering part includes a pair of roller plates fixedly connected to the lower ends of the linkage frame, a pair of rollers arranged in a left-right distribution are rotatably connected between the front and rear roller plates, an air vent is sleeved on the outer side of the pair of rollers, and a number of flexible pressure belts arranged at equal intervals are fixedly connected to the outer side of the air vent.

A gap is provided between the liquid guide plate and the limiting plate of the pressure plate.

[0010] Preferably, a monitoring unit is provided on the upper side of the flexible transmission unit on the left. The monitoring unit includes a beam frame fixed to the upper side of a pair of side plates. A guide groove is formed on the upper side of the beam frame. A second motor is fixedly connected to the front side of the beam frame. A reciprocating lead screw that is rotatably connected to the guide groove is fixedly connected to the end of the output shaft of the second motor. A reciprocating sleeve is threaded to the outer side of the reciprocating lead screw. A guide sleeve that is slidably connected to the guide groove is fixedly connected to the outer side of the reciprocating sleeve.

[0011] Preferably, the first near-infrared spectral sensor, the thickness sensor, and the first industrial camera are located on the left side of the positive pressure degreasing module, and the second near-infrared spectral sensor and the second industrial camera are located on the right side of the positive pressure degreasing module.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, through the flexible transmission section, positive pressure degreasing module, negative pressure oil absorption section, and vibration degreasing module, the flexible transmission section can flexibly carry and transport the rice crust. The positive pressure degreasing module can flexibly cover and position the rice crust and blow away the surface oil through positive pressure airflow and its follow-up covering and pressing section. The negative pressure oil absorption section simultaneously sucks up and recovers the oil. The vibration degreasing module uses vibration and its covering plate to limit the rice crust to perform secondary vibration degreasing and prevent longitudinal movement and collision. This realizes an automated oil reduction and anti-breakage device for producing rice crusts. Through the dual oil reduction mode of positive and negative pressure oil reduction and vibration degreasing, combined with the flexible positioning and limit anti-collision structure throughout the process, it can efficiently and evenly remove the residual oil on the surface and inside of the rice crust while greatly reducing the breakage of the rice crust caused by squeezing and collision. This solves the problem of low oil removal efficiency and high breakage rate caused by violent operation vibration of existing equipment. 2. In this invention, the monitoring unit, finished product inspection unit, and control box are designed to expand the detection range of the monitoring unit through reciprocating movement. This allows for the detection of the initial oil content, thickness, and surface condition of the rice crust before degreasing. The finished product inspection unit, in conjunction with the monitoring unit, can perform phased and final inspections of the degreasing effect and breakage status after initial and final degreasing. The PLC controller in the control box compares and analyzes the detection data from each stage, automatically adjusting the operating parameters of the positive pressure degreasing module, negative pressure oil suction unit, flexible transmission unit, and vibration degreasing module in real time. This enables the equipment to automatically match the optimal degreasing process according to the actual condition of the rice crust, adapting to the processing needs of rice crusts with different thicknesses and oil contents. This solves the problem that existing equipment lacks automated means to adjust degreasing parameters in real time according to the rice crust's condition, making it difficult to balance efficient oil reduction with low-damage and breakage prevention, and resulting in poor adaptability.

Detailed Implementation

[0015] Please see Figure 1-9 The present invention provides a technical solution: An automated oil-reducing and anti-breakage device for producing rice crust includes a base 1. The base 1 includes several support legs 11. A pair of side plates 12 arranged front to back are fixedly connected to the upper side of each support leg 11. Each side plate 12 has a through-hole 13 on its inner side. Flexible transmission parts 2 are installed on both the left and right sides of the pair of side plates 12. Each flexible transmission part 2 includes a pair of rollers 21 rotatably connected to the holes in the front and rear side plates 12. A flexible transmission belt 22 is sleeved on the outer side of the pair of rollers 21. A plurality of liquid passage holes 23 are equidistantly arranged through the inner side of the flexible transmission belt 22. A motor 24 is fixedly connected to the front end face of the front side plate 12. The output shaft end of the motor 24 is connected to... The left side roller 21 is fixedly connected, and a positive pressure degreasing module 4 is installed on the upper side of the left flexible conveyor section 2. The positive pressure degreasing module 4 includes a housing 41 fixed between a pair of side plates 12 and located on the upper side of the left flexible conveyor belt 22. A material passage 43 is opened on the lower side of the housing 41 in a transversely through manner. An air inlet pipe 42 is fixedly connected to the upper side of the housing 41 in a communicating manner. A blower 44 is installed on the upper side of the air inlet pipe 42. A base plate 46 is fixedly connected to the inner side of the housing 41. Several springs 47 are fixedly connected to the upper side of the base plate 46. A linkage frame 48 is fixedly connected to the upper side of the springs 47 and slidably connected to the notches on both sides of the base plate 46. A material passage 43 is installed on the lower side of the linkage frame 48. The upper follow-up pressing part 49, the lower side of the positive pressure oil removal module 4 is provided with a negative pressure oil suction part 3, the negative pressure oil suction part 3 includes a receiving shell 31 fixed inside the two side loading ports 13, the front side of the receiving shell 31 is fixedly connected with a suction pipe 32 that is arranged in a continuous manner, the suction pipe 32 is installed on the suction pipe 32, the lower right end of the suction pipe 32 is provided with an oil storage shell 5, the right side of the base 1 is provided with a vibration removal module 6; the vibration removal module 6 includes a base 61 provided on the right side of the base 1, the upper end face of the base 61 is fixedly connected with a rubber buffer 62, the upper side of the rubber buffer 62 is fixedly connected with a box shell 63, the right discharge port of the box shell 63 is fixedly connected with a discharge plate shell 64, the inner side of the box shell 63 is fixedly connected with There is a liquid guide plate 65 set at an inclined angle. An electric push rod 66 is installed on the upper inner wall of the housing 63. The lower end of the electric push rod 66 is fixedly connected to a pressure plate 67. A vibration motor 68 is installed on the front side of the housing 63. An oil drain pipe 69 is fixedly connected to the lower side of the housing 63 and is arranged in a continuous manner. The lower left end of the oil drain pipe 69 is set towards the upper opening of the oil storage shell 5. This arrangement allows the liquid guide plate 65 to guide the rice crust on its upper side towards the discharge plate shell 64. When the vibration motor 68 runs, it can drive the housing 63 and the liquid guide plate 65 to vibrate, thereby vibrating and removing oil from the rice crust on the liquid guide plate 65. The removed oil can be discharged into the oil storage shell 5 through the oil drain pipe 69.The receiving shell 31 is located inside the left flexible conveyor belt 22 and directly below the housing 41. The upper part of the left flexible conveyor belt 22 is located between the housing 41 and the receiving shell 31. This arrangement allows the left flexible conveyor section 2 to transport the rice crust to the positive pressure degreasing module 4 and the negative pressure oil absorption section 3 for preliminary oil removal. The right flexible conveyor section 2 is set at an inclined angle, with the left end of the liquid guide plate 65 located below the right end of the right flexible conveyor section 2. This arrangement allows the right flexible conveyor section 2 to transport the rice crust that has undergone preliminary oil removal to the upper left end of the liquid guide plate 65 of the vibration degreasing module 6. The follow-up pressing section 49 includes a pair of linked... The lower ends of the frame 48 are fixedly connected to roller plates 491. A pair of rollers 492, arranged left and right, are rotatably connected between the front and rear roller plates 491. A ventilation belt 493 is sleeved on the outside of the pair of rollers 492. Several flexible pressure belts 494, arranged at equal intervals, are fixedly connected to the outside of the ventilation belt 493. The upper plate of the linkage frame 48 is located below the air inlet pipe 42. A filter cover 45 is installed on the upper side of the blower 44. This arrangement ensures that the airflow delivered by the blower 44 to the air inlet pipe 42 is filtered by the filter cover 45 before entering the housing 41, preventing dust and impurities in the airflow from contaminating the rice crust. During the process, the airflow will push the linkage frame 48 downward and compress it. Spring 47 causes the follow-up pressing part 49 to move downward as a whole, thereby driving each flexible pressing belt 494 to press against the upper side of the rice crust moving to the right along the left flexible conveyor belt 22, thus preventing the rice crust from colliding or shifting under the action of airflow. The flexible pressing belts 494 and the ventilation belt 493 of the follow-up pressing part 49 also move cyclically, continuously performing flexible pressing and positioning on the rice crust passing through the material inlet 43 and the positive pressure degreasing module 4. The pressing plate 67 consists of a guide plate on the left and a limiting plate on the right. The pressing plate 67 is located above the liquid guide plate 65, and the tilt angle of the limiting plate of the pressing plate 67 is the same as the tilt angle of the liquid guide plate 65. A gap is provided between the plate 65 and the limiting plate of the pressing plate 67. This gap allows the guide plate of the pressing plate 67 to guide the rice crust falling on the upper left side of the liquid-passing guide plate 65 to the space between the limiting plate of the pressing plate 67 and the liquid-passing guide plate 65. The limiting plate of the pressing plate 67 longitudinally limits the rice crust on the upper side of the liquid-passing guide plate 65, ensuring that the rice crust maintains a stable longitudinal position during the vibration of the liquid-passing guide plate 65. This prevents the rice crust from colliding with each other due to longitudinal movement, thereby reducing breakage caused by collisions. The electric push rod 66 can adjust the longitudinal position of the pressing plate 67, allowing the pressing plate 67 to accommodate rice crust of different thicknesses.

[0016] like Figures 1-2 , Figures 7-9As shown, a monitoring unit 7 is provided on the upper side of the flexible transmission unit 2 on the left. The monitoring unit 7 includes a beam frame 701 fixed to the upper side of a pair of side plates 12. A guide groove 702 is provided on the upper side of the beam frame 701. A second motor 703 is fixedly connected to the front side of the beam frame 701. A reciprocating screw 704 that is rotatably connected to the guide groove 702 is fixedly connected to the end of the output shaft of the second motor 703. A reciprocating sleeve 705 is threadedly connected to the outer side of the reciprocating screw 704. A guide sleeve 706 that is slidably connected to the guide groove 702 is fixedly connected to the outer side of the reciprocating sleeve 705. A mounting shell 707 is fixedly connected to the lower side of the guide sleeve 706. A near-infrared spectral sensor 709 with the detection end facing downward and an industrial camera 71 are mounted on the inner side of the mounting shell 707. A thickness sensor 711 and an extension plate 708 are fixedly connected to the right side of the mounting housing 707. A near-infrared spectral sensor 712 with its detection end facing downwards and an industrial camera 713 are installed in the right port of the extension plate 708. A finished product detection unit 8 is installed on the upper side of the discharge plate housing 64. The finished product detection unit 8 includes a support frame 81 fixed to the upper side of the discharge plate housing 64. A near-infrared spectral sensor 82 with its detection end facing downwards and an industrial camera 83 are installed in the port of the support frame 81. A control box 9 is installed on the front end face of the front side plate 12. This configuration causes the motor 703 to drive the reciprocating screw 704 to rotate, which in turn drives the guide sleeve 706, the mounting housing 707, and the extension plate 708 via the reciprocating sleeve 705. The near-infrared spectral sensor 709, thickness sensor 711, industrial camera 710, near-infrared spectral sensor 712, and industrial camera 713 move back and forth along the guide groove 702, thereby expanding the monitoring range of the near-infrared spectral sensor 709, thickness sensor 711, industrial camera 710, near-infrared spectral sensor 712, and industrial camera 713. The finished product detection unit 8 can detect the degreasing effect and the breakage state of the rice crust after vibration degreasing. By comparing the detection data before and after, the PLC controller in the control box 9 determines the degreasing efficiency and adjusts the operating parameters of the vibration motor 68 of the vibration degreasing module 6 accordingly. The near-infrared spectral sensor 709, thickness sensor 711, and industrial camera 710 are located on the left side of the positive pressure degreasing module 4, while the near-infrared spectral sensor 712 and industrial camera 713 are located on the right side of the positive pressure degreasing module 4. On the right side of the positive pressure degreasing module 4, this setting enables the near-infrared spectral sensor 709, thickness sensor 711, and industrial camera 710 to detect the initial oil content, thickness, and surface condition of the rice crust before positive and negative pressure degreasing. Based on this, the control box 9 controls the electric push rod 66 to start and longitudinally adjust the pressing plate 67 to adapt to the thickness of the batch of rice crust. At the same time, the near-infrared spectral sensor 712 and industrial camera 713 can detect the degreasing effect and the cracking state of the rice crust after positive and negative pressure degreasing. By comparing the detection data before and after, the PLC controller in the control box 9 determines the degreasing efficiency and adjusts the operating parameters of the positive pressure degreasing module 4, the negative pressure oil suction section 3, and the left flexible transmission section 2 accordingly.

[0017] Workflow: The operation of the automated oil-reducing and anti-breakage equipment for producing rice crusts is as follows. Note that all electrical components in this application are externally powered and centrally controlled via control box 9. The fried rice crusts are evenly spread on the flexible conveyor belt 22 of the left flexible conveyor section 2. The left motor 24 is started to drive the left roller 21 to rotate, causing the flexible conveyor belt 22 to transport the rice crusts to the right. During transport, the rice crusts first pass under the monitoring section 7. Motor 703 drives the reciprocating screw 704 to rotate, which, through the reciprocating sleeve 705, drives the guide sleeve 706, mounting shell 707, and extension plate 708 to move back and forth along the guide groove 702, thereby expanding the reach of the near-infrared spectral sensor 709, thickness sensor 711, and industrial camera 1. The monitoring range of the near-infrared spectral sensor 710, near-infrared spectral sensor 712, and industrial camera 713 is monitored by the near-infrared spectral sensor 709, thickness sensor 711, and industrial camera 710 before the positive and negative pressure oil removal process. The initial oil content, thickness, and surface condition of the rice crust are detected, and the detection data is transmitted to the control box 9 in real time. Subsequently, the rice crust enters the housing 41 through the material inlet 43 and is located between the positive pressure oil removal module 4 and the negative pressure oil suction part 3. By starting the blower 44, airflow is delivered to the air inlet pipe 42, filtered by the filter cover 45, and then enters the housing 41. During this process, the airflow pushes down the linkage frame 48 and compresses the spring 47, causing the follow-up pressing part 49 to move downward as a whole, thereby driving each flexible pressing belt 494 to press against the left side of the flexible pressing part. The conveyor belt 22 moves to the right on the upper side of the rice crust to prevent it from colliding or shifting under the action of airflow. At the same time, the flexible pressure belts 494 and ventilation belts 493 of the follow-up pressing part 49 move in a cycle to continuously press and position the rice crust that passes through the material inlet 43 and the positive pressure degreasing module 4. During this process, the positive pressure airflow passes through the liquid passage holes 23 on the follow-up pressing part 49 and the flexible conveyor belt 22 to blow the surface oil off the rice crust. At the same time, the fan 33 of the negative pressure oil suction part 3 runs, sucking the blown-off oil through the receiving shell 31 and the suction pipe 32 and guiding it into the oil storage shell 5 for centralized recovery. After the positive and negative pressure degreasing, the rice crust continues to move to the right. The near-infrared spectral sensor 712 and the industrial camera 713 monitor the positive and negative pressure. The degreasing effect and breakage state of the rice crust after pressure degreasing are detected, and the detection data is transmitted to the control box 9 in real time. The PLC controller in the control box 9 compares the detection data with the initial data detected by the near-infrared spectral sensor 709, the thickness sensor 711 and the industrial camera 710 to determine the degreasing efficiency, and adjusts the air volume of the blower 44 of the positive pressure degreasing module 4, the suction force of the exhaust fan 33 of the negative pressure oil suction section 3 and the conveying speed of the left flexible transmission section 2 accordingly. Then the rice crust continues to be conveyed to the right by the left flexible transmission belt 22 and transitions to the right flexible transmission section 2 which is set at an inclined angle. Through the right flexible transmission section 2, the rice crust then falls into the upper left side of the liquid guide plate 65 of the vibration degreasing module 6.Based on the rice crust thickness data detected by the monitoring unit 7, the control box 9 controls the electric push rod 66 to start, longitudinally adjusting the pressing plate 67 to adapt to the thickness of this batch of rice crust. This allows the guide plate of the pressing plate 67 to guide the rice crust falling on the upper left side of the liquid guide plate 65 to between the limiting plate of the pressing plate 67 and the liquid guide plate 65. The limiting plate of the pressing plate 67 longitudinally limits the rice crust on the upper side of the liquid guide plate 65. The vibration motor 68 is started, and under the elastic support of the rubber buffer 62, it drives the housing 63 and the liquid guide plate 65 to vibrate, performing secondary vibration to remove oil from the rice crust on the liquid guide plate 65. This causes the residual oil inside and on the surface of the rice crust to further detach under the vibration and pass downward through the liquid guide plate 65, and be discharged into the oil storage tank 5 through the oil drain pipe 69. During the vibration process, the pressing plate 67... The limiting plate keeps the rice crust in a stable longitudinal position, preventing collisions between individual rice crusts due to longitudinal movement, thus reducing breakage caused by collisions. After degreasing, the rice crust moves towards the discharge plate 64 under the inclined guidance and vibration of the liquid guide plate 65, and is discharged through the discharge plate 64. The near-infrared spectral sensor 82 and industrial camera 83 in the finished product detection unit 8 detect the final degreasing effect and breakage state of the rice crust after vibration degreasing, and the detection data is fed back to the control box 9 in real time. The PLC controller in the control box 9 compares the data fed back by the finished product detection unit 8 with the previous detection data to determine the vibration degreasing efficiency, and adjusts the operating parameters of the vibration motor 68 of the vibration degreasing module 6 accordingly, so that the equipment adapts to the processing requirements of the current batch of rice crust, realizing the coordinated control of automated oil reduction and anti-breakage.
