A drying device for shredded papaya

Abstract

This invention relates to the field of food processing technology, specifically to a papaya shredding and drying device, comprising a base frame, a shredder, a conveyor belt, and an extrusion assembly. The extrusion assembly includes a support frame, a bearing frame, a first rotating shaft, a second rotating shaft, and a clamping belt. The extrusion assembly is configured to extrude the papaya shreds that have been shredded by the shredder and are located on the conveyor belt. The clamping belt, driven by the first and second rotating shafts, applies pressure to the papaya shreds passing below it, squeezing out a large amount of water contained in the papaya shreds. In this way, when the papaya shreds are subsequently placed in the dryer, since the water content has been reduced to a certain extent by the extrusion assembly, the drying efficiency will not be greatly affected by excessive moisture. It also avoids excessive energy consumption due to drying a large amount of excess water, thus achieving rational use of energy and improving the overall efficiency of the drying process.

Technical Field

[0001] This invention relates to the field of food processing technology, specifically to a papaya shredding and drying device. Background Technology

[0002] As we all know, papayas often need to be shredded during the production and processing of papayas. The traditional method of shredding is done manually with the help of knives, which is not only inefficient but also easy to injure workers' hands.

[0003] A search revealed that Chinese Patent Publication No. CN216707652U discloses a papaya fruit shredding device, which includes a shredding chamber, which is a hollow structure open at both ends. The shredding chamber is composed of a first chamber body and a second chamber body with the same shape and structure. The top of the first chamber body is integrally formed with a feeding hopper, and the second chamber body is fixed with a support foot. The shredding component includes a shredding cylinder, a connecting disc, a driven wheel, a drive motor, a drive wheel, and a transmission belt. The drive motor drives the shredding cylinder to rotate in the shredding chamber through the drive wheel, the driven wheel, the transmission belt, and the connecting disc. This utility model shredding device is designed to solve the problems existing in the existing shredding machine. It is designed with multiple components such as the shredding chamber and the shredding component, which can realize continuous and efficient shredding of papaya fruit, improve the shredding efficiency of papaya fruit, and the whole device has good stability. It is also easy to assemble, maintain, and repair.

[0004] Although the above technical solutions solve the problem of achieving continuous and efficient shredding of papaya fruit, the papaya shreds still contain a lot of water. Placing them directly in the dryer greatly affects the drying efficiency and is also a waste of energy. To solve the above problems, a papaya shredding and drying device is needed. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the present invention provides a papaya shredding and drying device to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a papaya shredding and drying device, comprising a base frame, a shredder, a conveyor belt, and an extrusion assembly. The shredder is installed on the side of the base frame, the conveyor belt is installed inside the base frame, and the extrusion assembly is installed on the top of the base frame. The extrusion assembly includes a support, a support frame, a first rotating shaft, a second rotating shaft, and a clamping belt. The support is fixedly disposed on the top of the base frame, the support frame is fixedly disposed between the supports, the first rotating shaft is rotatably disposed on one side of the support frame, the second rotating shaft is rotatably disposed on the other side of the support frame, and the clamping belt is disposed between the first rotating shaft and the second rotating shaft.

[0009] Preferably, it further includes a first motor, a first pulley, and a first transmission belt. The first motor is mounted on the top of the base frame, the first pulley is fixedly disposed on the side of the second rotating shaft, and the first transmission belt is driven between the first motor and the first pulley.

[0010] Furthermore, the shredder includes a protective frame, a second pulley, a rotating shaft, and a shredding roller. The protective frame is fixedly disposed on the top of the base frame, the second pulley is rotatably disposed on the side of the protective frame, the rotating shaft is fixedly disposed on the side of the second pulley, and the shredding roller is fixedly disposed on the rotating shaft.

[0011] Furthermore, it also includes a mounting block and a cleaning brush. The mounting block is fixedly disposed on both sides of the protective frame, and the cleaning brush is fixedly disposed on the side of the mounting block. One end of the cleaning brush is in contact with the wiping roller.

[0012] A further embodiment includes a second motor, a third pulley, and a second transmission belt. The second motor is installed inside the base frame, and the output shaft of the second motor passes through the base frame and extends to the outside. The third pulley is fixedly mounted on the output shaft of the second motor, and the second transmission belt is driven between the second pulley and the third pulley.

[0013] Based on the aforementioned solution, it further includes a slide groove, a third rotating shaft, a screw, a fixing pin, and a spring. The slide groove is formed on both sides of the support frame. The third rotating shaft is rotatably disposed on the top of the support frame, and both ends of the third rotating shaft are slidably disposed with the slide groove. The screw is threadedly disposed on both sides of the top of the support frame, and one end of the screw is threadedly disposed with the third rotating shaft.

[0014] Furthermore, based on the aforementioned solution, it also includes a conveyor plate and a drying drum. The conveyor plate is fixedly installed on the side of the bottom frame, and the drying drum is placed on the side of the bottom frame. The drying drum is connected to the conveyor plate.

[0015] (III) Beneficial Effects

[0016] This papaya shredding and drying device includes a base frame, a shredder, a conveyor belt, and an extrusion assembly. The extrusion assembly includes a support frame, a bearing frame, a first rotating shaft, a second rotating shaft, and a clamping belt. The extrusion assembly is designed to extrude the papaya shreds that have been shredded by the shredder and are located on the conveyor belt. The clamping belt, driven by the first and second rotating shafts, applies pressure to the papaya shreds passing below, squeezing out a large amount of moisture. Therefore, when the papaya shreds are subsequently placed in the dryer, the moisture content has been reduced to a certain extent by the extrusion assembly, preventing excessive moisture from significantly affecting the drying efficiency. This also avoids excessive energy consumption due to drying large amounts of excess moisture, achieving rational energy utilization and improving the overall efficiency of the drying process. The cooperation of various components such as the grater, conveyor belt, and extrusion assembly enables the entire papaya processing process to proceed continuously and efficiently. The grater first shreds the papaya, and the shredded papaya falls onto the conveyor belt. As the conveyor belt runs, it passes through the extrusion assembly in sequence to remove water. Subsequently, it can be directly transported to the dryer and other next processing stages. The various stages are closely connected and orderly, reducing manual intervention and intermediate downtime. From shredding to initial water removal, the process is completed continuously, which helps to improve the overall efficiency of processing papaya into dried products. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] See Figures 1-5 A papaya shredding and drying device includes a base frame 1, a shredder 2, a conveyor belt 3, and an extrusion assembly 4.

[0025] Preferably, the base frame 1 serves as the basic support structure for the entire device, providing installation positions and a stable working platform for other components. The grater 2 is installed on the side of the base frame 1. When the papaya is placed in the working area of ​​the grater 2, the papaya is shredded through the shredding structure inside the grater 2. Its installation height and angle should be adapted to the starting end of the conveyor belt 3 so that the shredded papaya can fall smoothly into the conveyor belt 3. The conveyor belt 3 is installed inside the base frame 1, and its two ends are connected to the pre-set bearing seats on the base frame 1 to form a circular conveying path. The upper surface of the conveyor belt 3 is flush with or slightly lower than the discharge port of the grater 2 to ensure that the papaya shreds can fall accurately onto the conveyor belt 3. Furthermore, the operating speed of the conveyor belt 3 should match the shredding speed of the grater 2 to avoid material accumulation or untimely conveying.

[0026] The extrusion assembly 4 includes a support 5, a bearing frame 6, a first rotating shaft 7, a second rotating shaft 8, and a clamping belt 9.

[0027] Preferably, the extrusion assembly 4 is located at the top of the base frame 1, wherein the bottom of the bracket 5 is fixed to the top of the base frame 1 by welding to ensure the vertical installation of the bracket 5 and provide stable support for the bearing frame 6. The bearing frame 6 is horizontally fixed between the brackets 5, and bearing seats for mounting the first rotating shaft 7 and the second rotating shaft 8 are respectively provided on both sides of the bearing frame 6. The first rotating shaft 7 and the second rotating shaft 8 are installed parallel to each other on both sides of the bearing frame 6 and can rotate freely within the bearing seats (not shown). The clamping belt 9 is wrapped around the first rotating shaft 7 and the second rotating shaft 8 to form a recirculating clamping belt 9 system. When the papaya shreds move to the bottom of the extrusion assembly 4 with the conveyor belt 3, the clamping belt 9 rotates through the rotation of the first rotating shaft 7 and the second rotating shaft 8 to extrude the papaya shreds. The squeezing operation removes some of the moisture, making it more conducive to the subsequent drying process. The support frame 6 has grooves 22 on both sides. The two ends of the third rotating shaft 23 are embedded in the grooves 22, allowing it to slide up and down within the grooves 22 to adjust the distance between the third rotating shaft 23 and the first and second rotating shafts 8, thereby changing the squeezing tightness of the clamping band 9. The screw 24 is installed by threaded connections to threaded holes on both sides of the top of the support frame 6. One end of the screw 24 engages with a threaded hole on the third rotating shaft 23. When the screw 24 is rotated, its rotational motion is converted into linear motion of the third rotating shaft 23 within the grooves 22, thus adjusting the squeezing tightness of the clamping band 9. The fixing pin 25 is rotatably mounted on the side of the support frame 6 via a pin shaft. Spring 2... One end of spring 26 is fitted onto the side protrusion of fixing pin 25, and the other end is fitted onto the side protrusion of third rotating shaft 23. During the up-and-down movement of third rotating shaft 23, spring 26 buffers and maintains the relative position of fixing pin 25 and third rotating shaft 23, preventing excessive shaking or abnormal displacement of third rotating shaft 23 during operation, ensuring stable operation of extrusion assembly 4 and consistent extrusion effect. Slide grooves 22 are provided on both sides of the bearing frame 6. Both ends of third rotating shaft 23 are embedded in the slide grooves 22, allowing it to slide up and down within the slide grooves 22 to adjust the distance between third rotating shaft 23 and the first and second rotating shafts 8, thereby changing the extrusion tightness of clamp 9. Screw 24 is threaded to the threads on both sides of the top of bearing frame 6. The screw 24 is installed with a threaded hole on the third rotating shaft 23. When the screw 24 is rotated, its rotational motion is converted into linear motion of the third rotating shaft 23 in the slide groove 22, thereby adjusting the degree of compression of the clamping band 9. The fixing pin 25 is rotatably mounted on the side of the bearing frame 6 via a pin shaft. One end of the spring 26 is fitted onto the side protrusion of the fixing pin 25, and the other end is fitted onto the side protrusion of the third rotating shaft 23. During the up-and-down movement of the third rotating shaft 23, the spring 26 buffers and maintains the relative position of the fixing pin 25 and the third rotating shaft 23, preventing excessive shaking or abnormal displacement of the third rotating shaft 23 during operation, and ensuring the stable operation of the extrusion assembly 4 and the consistency of the extrusion effect.

[0028] First, refer to Figure 2 In this embodiment, it also includes a first motor 10, a first pulley 11, and a first transmission belt 12.

[0029] Preferably, the first motor 10 is mounted on the top side of the base frame 1 and fixed to a dedicated motor mounting bracket (not shown) by bolts. The motor mounting bracket is welded to the base frame 1 to ensure the stability of the first motor 10 during operation and prevent vibration and displacement. The first pulley 11 is fixedly disposed on the side of the second rotating shaft 8 and is tightly fitted to the second rotating shaft 8 by a key connection to ensure the synchronicity of the two during rotation. The first transmission belt 12 is driven between the output shaft pulley of the first motor 10 and the first pulley 11, ensuring both power delivery and transmission efficiency. The system effectively transmits power while avoiding slippage due to excessive looseness or increased load on the first motor 10 and wear on the belt due to excessive tightness. When the first motor 10 starts, its rotational power is transmitted to the first pulley 11 via the first transmission belt 12, which in turn drives the second rotating shaft 8 to rotate. Due to the transmission connection of the clamping belt 9, the first rotating shaft 7 also rotates synchronously, causing the clamping belt 9 to start operating. This squeezes the papaya shreds conveyed on the conveyor belt 3, squeezing out some of the moisture from the papaya shreds, making them easier to dry in subsequent processes and improving drying efficiency and quality.

[0030] Then, refer to Figure 4 In this embodiment, the grater 2 includes a protective frame 13, a second pulley 14, a rotating shaft 15, and a grating roller 16.

[0031] Preferably, the protective frame 13 is located in a specific position within the entire structure of the shredder 2. It is fixedly installed on the top of the bottom frame 1, and its function is to provide protection for the internal moving parts of the shredder 2, preventing the user from accidentally contacting the moving parts and getting injured during operation. It also plays a certain role in preventing dust and foreign object intrusion into the internal parts. The second pulley 14 is rotatably installed on the side of the protective frame 13. This component, in cooperation with an external power transmission device (such as a belt), transmits power to the rotating parts of the entire shredder 2. Its rotatable arrangement allows it to rotate freely under power drive, thereby driving other connected components to work together. The rotating shaft 15 is fixedly installed. On the side of the second pulley 14, it serves as a key component connecting the second pulley 14 and the grating roller 16, playing a role in transmitting torque. When the second pulley 14 rotates under the action of power, the rotating shaft 15 rotates synchronously with it and transmits the rotational power to the grating roller 16, ensuring that the grating roller 16 can perform grating operations. The grating roller 16 is fixedly mounted on the rotating shaft 15 and is the core component for realizing the grating function. Its surface is provided with grating blades of specific shape and specifications. Under the action of power transmitted by the rotating shaft 15, the grating roller 16 rotates, and the food to be grated comes into contact with the blades on the surface of the grating roller 16, thereby being processed into shreds.

[0032] Secondly, see Figure 4 In this embodiment, the mounting block 17 and the cleaning brush 18 are also included.

[0033] Preferably, the mounting block 17 is fixedly installed on both sides of the protective frame 13. It mainly serves to connect and support the cleaning brush 18, providing a stable installation position for the cleaning brush 18. By fixing the mounting block 17 to both sides of the protective frame 13, it ensures that the cleaning brush 18 can be accurately positioned near the grating roller 16 to achieve the cleaning function. The cleaning brush 18 is fixedly installed on the side of the mounting block 17, with one end in contact with the grating roller 16. The function of the cleaning brush 18 is to clean the surface of the grating roller 16 during or after the operation of the grater 2. When the grating roller 16 rotates, the cleaning brush 18 in contact with it can promptly clean the food residue attached to the surface of the grating roller 16, avoiding the accumulation of residue that affects the grating effect and equipment performance. By fixing the cleaning brush 18 to the side of the mounting block 17, it ensures that its contact position with the grating roller 16 is stable, achieving continuous and effective cleaning operation.

[0034] Again, see Figure 2 In this embodiment, it also includes a second motor 19, a third pulley 20, and a second transmission belt 21.

[0035] Preferably, the second motor 19 is installed inside the base frame 1. It is one of the power sources for the shredder 2, providing power support for its operation. Its output shaft passes through the base frame 1 and extends to the outside. This design allows the output shaft to connect with components outside the base frame 1, thereby transmitting the power generated by the second motor 19 to drive the relevant components of the shredder 2. The third pulley 20 is fixedly mounted on the output shaft of the second motor 19. It is tightly connected to the output shaft of the second motor 19 and can rotate synchronously with the rotation of the output shaft. The main function of the third pulley 20 is to act as a power source. One node of the transmission transmits the power of the second motor 19 to the required components via belt drive. The second transmission belt 21 is driven between the second pulley 14 and the third pulley 20. It serves as the medium for power transmission, transmitting the power generated by the rotation of the third pulley 20 with the output shaft of the second motor 19 to the second pulley 14. By being tensioned on the two pulleys, when the third pulley 20 rotates, it drives the second pulley 14 to rotate synchronously, thereby causing the rotating shaft 15 and the wiping roller 16 connected to the second pulley 14 to operate, thus realizing the normal operation of the wiping device 2.

[0036] Finally, see Figure 1 In this embodiment, a conveyor plate 27 and a drying drum 28 are also included.

[0037] Preferably, the conveyor plate 27 is fixedly installed on the side of the base frame 1. Its function is to provide a conveying channel for the shredded food processed by the shredding roller 16. By fixing the conveyor plate 27 to the side of the base frame 1, the shredded food falling from the shredding roller 16 can fall directly onto the conveyor plate 27. With the guidance of the conveyor plate 27, the food is conveyed to a designated position for convenient subsequent processing. The drying barrel 28 is placed on the side of the base frame 1 and is connected to the conveyor plate 27. The main function of the drying barrel 28 is to dry the shredded food sent by the conveyor plate 27, removing the moisture from the food so that it can be preserved or further processed. Its design of being connected to the conveyor plate 27 ensures that the shredded food can smoothly enter the drying barrel 28 from the conveyor plate 27, realizing a continuous operation process from shredding to drying.

[0038] Working principle:

[0039] The papaya shredding and drying device begins with the worker starting the first motor 10. Once started, the first motor 10 transmits its rotational power to the first pulley 11 via the first transmission belt 12. The first pulley 11 is fixed to the side of the second rotating shaft 8 via a key connection, thus driving the second rotating shaft 8 to rotate. Since the clamping belt 9 surrounds the first rotating shaft 7 and the second rotating shaft 8, and the two are connected by a transmission, the first rotating shaft 7 also rotates synchronously. The clamping belt 9 begins to operate, and the second motor 19 is started. The second motor 19 is installed inside the base frame 1, and its output shaft extends through the base frame 1 to the outside. The second motor 19 drives the third pulley 20, which is fixed to its output shaft, to rotate. The third pulley 20 transmits power to the second pulley 14 via the second transmission belt 21. The second pulley 14 is rotatably mounted on the side of the protective frame 13. The second pulley 14 drives the connected rotating shaft 15 to rotate. The rotating shaft 15 is fixed to the side of the second pulley 14, thereby driving the grating roller 16 to rotate, and the grater 2 begins to work.

[0040] During the shredding process, the cleaning brush 18 cleans the surface of the shredding roller 16. The cleaning brush 18 is fixed to the side of the mounting block 17, which is fixed to both sides of the protective frame 13. One end of the cleaning brush 18 is in contact with the shredding roller 16 to promptly remove papaya residue adhering to the surface of the shredding roller 16, preventing residue accumulation from affecting the shredding effect and equipment performance. The shredded papaya falls from the shredding roller 16 onto the conveyor plate 27 fixed to the side of the bottom frame 1. When the papaya shreds move with the conveyor belt 3 to the extrusion assembly 4, the clamping belt 9 extrudes the papaya shreds. The first rotating shaft 7 and the second rotating shaft 8 are parallel to each other and can rotate freely in the bearing seats on both sides of the bearing frame 6. The clamping belt 9 surrounds both shafts. A recirculating rotating system is formed on top, and the degree of compression of the clamping belt 9 can be adjusted by rotating the screw 24. The screw 24 is installed by threaded connection with the threaded holes on both sides of the top of the support frame 6, and one end is connected to the threaded hole on the third rotating shaft 23. When the screw 24 is rotated, the rotational motion of the screw 24 is converted into the linear motion of the third rotating shaft 23 in the slide groove 22. The two ends of the third rotating shaft 23 are embedded in the slide groove 22 on both sides of the support frame 6 and can slide up and down, thereby changing the distance between the third rotating shaft 23 and the first rotating shaft 7 and the second rotating shaft 8, so as to adjust the tightness of the compression of the clamping belt 9. After being squeezed and dehydrated, the papaya shreds continue to move with the conveyor belt 3 and finally fall from the conveyor belt 3 into the drying barrel 28 that is connected to the side of the bottom frame 1.
