Description

Technical Field

[0001] This invention relates to the field of yam processing equipment, specifically to a yam food processing equipment and method. Background Technology

[0002] Yam is rich in protein, vitamins, and various trace elements, and has the effects of strengthening the spleen and stomach, nourishing the kidneys and replenishing essence. It is widely used in the food processing industry and can be made into various products such as yam cakes, yam slices, and yam powder. With the increasing market demand for yam food products, its processing efficiency and quality are becoming increasingly critical, and the requirements for processing equipment are also constantly improving. Currently, traditional yam food processing equipment suffers from numerous problems. On the one hand, most equipment has limited functionality; peeling, washing, and cutting processes often require multiple machines, leading to frequent material transfers between machines. This not only increases labor costs but also results in low processing efficiency and poses a risk of contamination during transport. On the other hand, in the peeling and washing stage, some equipment uses simple friction peeling methods, which are insufficient to completely remove the yam skin. Subsequent washing often relies on manual scrubbing or ordinary water rinsing, resulting in poor cleaning effectiveness. Furthermore, washing water is mostly discharged directly, causing water waste. In addition, traditional cutting equipment has fixed cutting specifications, failing to meet the diverse needs of different food processing methods for yam shapes and sizes, thus limiting product innovation and expansion. Therefore, there is an urgent need for a multi-functional, highly efficient, water-saving yam food processing machine with adjustable cutting specifications to improve the overall level of yam food processing. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a processing equipment and method for yam food products, which solves the problems of traditional yam food processing equipment such as single function, low processing efficiency, poor cleaning effect, water waste, and inability to adjust cutting specifications. It realizes one-stop processing of peeling, cleaning, and cutting, saves water and energy, and can flexibly adjust cutting specifications, thereby improving processing quality and efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a processing equipment for yam food, comprising a processing table, a roller conveyor fixedly installed on one side of the top of the processing table, a housing fixedly installed near the top of the roller conveyor at the top of the processing table, movable shafts movably installed on both sides of the bottom of the housing, a plurality of grinding wheels uniformly fixedly installed on the outer diameter of the movable shafts, a cleaning chamber fixedly installed in the middle of the housing, a plurality of cleaning grooves uniformly opened at the bottom of the cleaning chamber, short shafts movably installed inside the cleaning grooves, multi-bladed brush plates fixedly installed at the bottom of the short shafts, a belt conveyor fixedly installed on the other side of the top of the processing table, a fixed bracket fixedly installed near the top of the belt conveyor at the top of the processing table, a movable bracket movably installed inside the fixed bracket, two guide rods fixedly installed on the lower side of the inner side of the movable bracket, a plurality of movable blocks uniformly movably installed on the outer diameter of the guide rods, and cutting blades fixedly installed at the bottom of the movable blocks.

[0005] Preferably, a driven bevel gear is fixedly installed at the top of each short shaft, and a drive shaft is movably installed on the upper side of the inside of the cleaning chamber. A driving bevel gear is fixedly installed on the outer diameter of the drive shaft near each driven bevel gear, and the driving bevel gear is meshed with the inner end of the corresponding driven bevel gear.

[0006] Preferably, both ends of the drive shaft extend to the outside of the cleaning chamber and are movably mounted on the inner side wall of the housing. Synchronous pulleys are fixedly mounted on one outer diameter of the drive shaft and one outer diameter of the two movable shafts. The outer diameters of the synchronous pulleys are connected by a synchronous belt. A DC motor is fixedly mounted on one end of the housing, and the drive end of the DC motor is fixedly mounted on one end of the drive shaft. An inlet is provided at one end of the housing near the lower position of the DC motor.

[0007] Preferably, a return water tank is provided inside the processing table near the lower part of the roller conveyor. A filter screen is fixedly installed inside the return water tank. A conveying pump is fixedly installed on the lower front side of the processing table. The input end of the conveying pump extends into the return water tank through a pipe. A water supply pipe is fixedly installed at the output end of the conveying pump. The end of the water supply pipe is fixedly installed at one end of a multi-port pipe. Several branch pipes are evenly fixedly installed on the inner side of the multi-port pipe, and the ends of the branch pipes all extend into the interior of the corresponding side of the cleaning tank.

[0008] Preferably, a rotating column is movably installed on the upper inner side of the movable bracket. Several arc-shaped grooves are opened on the outer diameter of the middle part of the rotating column, and the pitch of the arc-shaped grooves gradually increases from the middle to both sides. The top of each movable block is fixedly installed with a round-headed pin, and the end of the round-headed pin is movably disposed inside the arc-shaped groove on the corresponding side.

[0009] Preferably, a hydraulic cylinder is fixedly installed at the top center of the fixed bracket, and the driving end of the hydraulic cylinder is fixedly installed at the top center of the movable bracket.

[0010] Preferably, a worm gear reducer is fixedly installed on one side of the outer diameter of the rotating column, and an adjusting motor is fixedly installed on one side of the top of the movable bracket, with the driving end of the adjusting motor fixedly installed at the input end of the worm gear reducer.

[0011] A method for processing yam food includes the following steps: Step 1: First, place the yam to be processed onto the roller conveyor through the feed port, start the roller conveyor to transport the yam into the shell, and keep it moving on the roller conveyor. Step 2: Start the DC motor, and use the synchronous pulley and synchronous belt to drive the two movable shafts and the transmission shaft to rotate. The movable shafts drive all the grinding wheels to rotate, and rub the outer surface of the yam to peel it. Step 3: Turn on the delivery pump to pump out the cleaning water from the return water tank and send it into each cleaning tank through the water supply pipe, multi-port pipe and branch pipe. Then, the rotating drive shaft, driving bevel gear and driven bevel gear drive all the multi-blade brushes to rotate at high speed, breaking the clean water into fine water droplets. These fine water droplets mix with air to form a high-speed water vapor fluid, which powerfully scrubs the surface of the yam to remove the residual outer skin and dirt. The wastewater generated from the cleaning is returned to the return water tank for recycling after passing through the filter screen. Step 4: After peeling and cleaning, the yams are fed onto a belt conveyor via a roller conveyor. At this time, the hydraulic cylinder is activated, which drives the movable support to descend, causing all the cutting blades to descend and dice or cut the yams. Finally, the yams are discharged from the other end of the belt conveyor.

[0012] This invention provides a processing device and method for yam food products. It has the following beneficial effects: 1. This invention integrates multiple key processes of yam processing, such as peeling, cleaning, and cutting, into one unit. Through the coordinated operation of components such as roller conveyors, grinding wheels, cleaning chambers, belt conveyors, and cutting blades, it realizes one-stop processing of yam from raw materials to semi-finished products, which greatly reduces the time loss of equipment changeover and material handling in traditional processing, significantly improves overall processing efficiency, and reduces labor costs.

[0013] 2. This invention achieves deep cleaning of the yam surface through the dual action of a grinding wheel and a multi-bladed brush. The grinding wheel performs initial peeling through rotational friction, while the multi-bladed brush disperses clean water to form a high-speed water vapor fluid, which effectively removes residual outer skin and stubborn dirt from the yam surface, ensuring the cleanliness of the yam and providing high-quality raw materials for subsequent processing.

[0014] 3. The components such as the return water tank, filter screen, and conveying pump set in this invention constitute a water circulation system. The wastewater generated during cleaning is filtered by the filter screen and then pumped back into the cleaning tank by the conveying pump for recycling, which greatly reduces the waste of water resources, conforms to the concept of green environmental protection, and also reduces the water cost of enterprises.

[0015] 4. By adjusting the coordination of the motor, worm gear reducer and rotating column, the spacing of the cutting blades can be flexibly adjusted. Due to the change in the pitch of the arc-shaped groove on the rotating column, the cutting blades can be synchronously extended or retracted at equal intervals to both sides, thereby accurately controlling the length of the yam cubes and segments, meeting the diverse needs of different food processing for yam specifications, and enhancing the versatility and practicality of the equipment.

[0018] The technical solutions in 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. Example

[0019] Please see the appendix Figure 1 -Appendix Figure 7 This invention provides a processing device for yam food products, such as... Figure 1As shown, the equipment includes a processing table 1, which serves as the basic load-bearing structure for the entire device, providing a stable mounting platform for all components. A roller conveyor 2 is fixedly installed on one side of the top of the processing table 1. The roller conveyor 2 consists of multiple parallel rollers, driven by a motor to rotate, and is used to smoothly transport the yams to be processed to the subsequent processing area. A housing 3 is fixedly installed on the top of the processing table 1, near the upper part of the roller conveyor 2. The housing 3 serves to protect and house the internal processing components, preventing debris from splashing during processing, and providing a closed space for peeling and cleaning processes. The inner bottom of the housing 3... Movable shafts 4 are movably mounted on both sides, and the movable shafts 4 are connected to the housing 3 via bearings, allowing them to rotate flexibly. Several grinding wheels 5 are evenly fixedly mounted on the outer diameter of the movable shafts 4. The surfaces of the grinding wheels 5 are made of a rough abrasive material. When the movable shafts 4 rotate, the grinding wheels 5 can rub and peel the yam surface. A cleaning chamber 6 is fixedly installed in the center of the housing 3. The cleaning chamber 6 is an independent enclosed space used for deep cleaning of the peeled yam. Several cleaning troughs 7 are evenly opened at the bottom of the cleaning chamber 6. The cleaning troughs 7 are used to hold cleaning water and install cleaning components. Short shafts are movably mounted inside each of the cleaning troughs 7. 8. The short shaft 8 is also connected to the inner wall of the cleaning tank 7 via bearings. A multi-bladed brush plate 9 is fixedly installed at the bottom of each short shaft 8. The multi-bladed brush plate 9 consists of multiple radially arranged brush blades, which can generate a strong water flow impact force when rotating. A belt conveyor 23 is fixedly installed on the other side of the top of the processing table 1. The belt conveyor 23 transports the cleaned yam to the cutting station through the circulating rotation of the belt. A fixed bracket 24 is fixedly installed at the top of the processing table 1 near the upper position of the belt conveyor 23. The fixed bracket 24 provides a stable support foundation for the cutting device. The internal movement of the fixed bracket 24... A movable support 25 is installed, which can move up and down within the fixed support 24 to achieve the lifting and lowering action of the cutting blade 31. Two guide rods 28 are fixedly installed on the lower inside of the movable support 25. The guide rods 28 serve to guide and limit, ensuring that the movable block 29 remains stable during movement. Several movable blocks 29 are evenly installed on the outer diameter of the guide rods 28. The movable blocks 29 can slide on the guide rods 28. The bottom end of each movable block 29 is fixedly installed with a cutting blade 31. The cutting blade 31 is made of high-strength stainless steel and has a sharp cutting edge, used for dicing or cutting yams.

[0020] In this embodiment, a driven bevel gear 10 is fixedly installed at the top of each short shaft 8. The driven bevel gear 10 is used to transmit power and realize the rotation of the short shaft 8. A transmission shaft 11 is movably installed on the upper side of the inside of the cleaning chamber 6. The transmission shaft 11 is mounted on the top of the cleaning chamber 6 through bearings and can rotate stably. A driving bevel gear 12 is fixedly installed on the outer diameter of the transmission shaft 11 near each driven bevel gear 10. The driving bevel gear 12 is meshed with the inner end of the corresponding driven bevel gear 10. Through this gear transmission method, the rotational power of the transmission shaft 11 is transmitted to the short shaft 8, thereby driving the multi-blade brush plate 9 to rotate.

[0021] Furthermore, both ends of the drive shaft 11 extend to the outside of the cleaning chamber 6 and are movably mounted on the inner wall of the housing 3 to ensure the stability of the drive shaft 11 during rotation. Synchronous pulleys 13 are fixedly mounted on one outer diameter of the drive shaft 11 and one outer diameter of the two movable shafts 4. The surface of the synchronous pulleys 13 is provided with a toothed structure that matches the synchronous belt 14. The outer diameters of the synchronous pulleys 13 are connected by the synchronous belt 14, which is an annular rubber belt with teeth on the inner side, enabling reliable power transmission and ensuring synchronous rotation between the drive shaft 11 and the movable shafts 4. A DC motor 15 is fixedly mounted on one end of the housing 3, and the drive end of the DC motor 15 is fixedly mounted on one end of the drive shaft 11. The DC motor 15 serves as the power source for the peeling and cleaning process of the entire equipment. By driving the drive shaft 11 to rotate, it drives other related components to operate. An inlet 22 is provided at one end of the housing 3 near the lower position of the DC motor 15. The inlet 22 is the entrance for yam to enter the equipment. Its size and shape are designed to facilitate the smooth entry of yam into the roller conveyor 2.

[0022] Furthermore, a return water tank 16 is provided inside the processing table 1 near the lower part of the roller conveyor 2. The return water tank 16 is used to collect wastewater generated during the cleaning process. A filter screen 17 is fixedly installed inside the return water tank 16. The filter screen 17 can intercept impurities and debris in the wastewater and prevent them from entering the water circulation system. A conveying pump 18 is fixedly installed on the lower front side of the processing table 1. The conveying pump 18 is used to extract and pressurize the wastewater in the return water tank 16 and convey it. The input end of the conveying pump 18 extends into the interior of the return water tank 16 through a pipe. To ensure smooth wastewater extraction, a water delivery pipe 19 is fixedly installed at the output end of the delivery pump 18. The water delivery pipe 19 is used to transport pressurized wastewater. The end of the water delivery pipe 19 is fixedly installed at one end of the multi-port pipe 20. The multi-port pipe 20 plays a diversion role, distributing the wastewater evenly to each branch pipe 21. Several branch pipes 21 are evenly fixedly installed on the inner side of the multi-port pipe 20, and the ends of the branch pipes 21 extend into the interior of the corresponding side cleaning tank 7, so that the wastewater can be accurately delivered to each cleaning tank 7, realizing the recycling of water resources.

[0023] Furthermore, a rotating column 26 is movably installed on the upper side of the interior of the movable bracket 25. The rotating column 26 is installed in the movable bracket 25 through bearings and can rotate freely. Several arc-shaped grooves 27 are opened on the outer diameter of the middle part of the rotating column 26, and the pitch of the arc-shaped grooves 27 gradually increases from the middle to both sides. This special arc-shaped groove 27 design is the key structure for realizing the adjustment of the spacing of the cutting blade 31. The top of each movable block 29 is fixedly installed with a round-headed pin 30, and the end of the round-headed pin 30 is movably set in the corresponding side arc-shaped groove 27. The round-headed pin 30 can slide in the arc-shaped groove 27. When the rotating column 26 rotates, it drives the round-headed pin 30 to move, thereby causing the movable block 29 and the cutting blade 31 to produce corresponding displacements.

[0024] Furthermore, a hydraulic cylinder 32 is fixedly installed at the top center of the fixed bracket 24, and the drive end of the hydraulic cylinder 32 is fixedly installed at the top center of the movable bracket 25. The hydraulic cylinder 32 is powered by the hydraulic system and can precisely control the lifting and lowering of the movable bracket 25, thereby achieving precise cutting of the yam by the cutting blade 31.

[0025] Furthermore, a worm gear reducer 33 is fixedly installed on one side of the outer diameter of the rotating column 26. The worm gear reducer 33 is used to reduce the speed and increase the torque, so that the rotation of the rotating column 26 is more stable and precise. An adjusting motor 34 is fixedly installed on one side of the top of the movable bracket 25, and the driving end of the adjusting motor 34 is fixedly installed on the input end of the worm gear reducer 33. The adjusting motor 34 serves as the power source for adjusting the cutting specifications. By driving the worm gear reducer 33, it drives the rotating column 26 to rotate, thereby realizing the flexible adjustment of the spacing of the cutting blades 31.

[0026] Working principle: First, the yam to be processed is placed on the roller conveyor 2 through the feed port 22. The motor of the roller conveyor 2 is started, driving the rollers to rotate and transporting the yam into the shell 3, where it continues to move on the roller conveyor 2. Then, the DC motor 15 is started, and the drive end of the DC motor 15 drives the transmission shaft 11 to rotate. The synchronous pulley 13 on the outer diameter of the transmission shaft 11 is driven by the synchronous belt 14, driving the two movable shafts 4 to rotate synchronously. This, in turn, drives all the grinding wheels 5 on the outer diameter of the movable shafts 4 to rotate at high speed. The abrasive material on the surface of the grinding wheels 5 is used to rub and peel the outer surface of the yam. The peeled yam continues to move on the roller conveyor 2, and... Below the cleaning chamber 6, the delivery pump 18 is turned on. The delivery pump 18 pumps out the cleaning water filtered by the filter screen 17 from the return water tank 16, and sends it through the water supply pipe 19 into the multi-way pipe 20. Then, it is distributed through the multi-way pipe 20 to each branch pipe 21, and finally sent into all the cleaning tanks 7. When the drive shaft 11 rotates, the driving bevel gear 12 on its outer diameter rotates accordingly. The driving bevel gear 12 meshes with the driven bevel gear 10, driving all the driven bevel gears 10 and the short shaft 8 to rotate, thereby driving all the multi-blade brushes 9 to rotate at high speed. The multi-blade brushes 9 disperse the clean water sent into the cleaning tank 7 into fine water droplets. These fine water droplets mix with air to form high-speed water... The steam-fluid system vigorously scrubs the surface of the yam, effectively removing residual skin and dirt. The wastewater generated during washing is filtered through filter 17 to remove impurities and then recycled back into the return water tank 16. The peeled and washed yams are then fed onto the belt conveyor 23 via roller conveyor 2 for further transport. At this time, hydraulic cylinder 32 is activated, and its drive end pushes the movable support 25 downwards, causing all the cutting blades 31 inside the movable support 25 to descend synchronously, dicing or cutting the yams on the belt conveyor 23. Finally, the processed yams are discharged from the other end of the belt conveyor 23. Furthermore, when it is necessary to adjust the dicing or cutting length of the yams... The regulating motor 34 is started, and the drive end of the regulating motor 34 drives the rotating column 26 to rotate through the worm gear reducer 33. The arc-shaped groove 27 on the surface of the rotating column 26 rotates accordingly, causing the round-headed pin 30 to move within the arc-shaped groove 27. With the limiting effect of the guide rod 28, the round-headed pin 30 drives the movable block 29 to move along the direction of the guide rod 28. Since the pitch of the arc-shaped groove 27 gradually increases from the middle to both sides, when the rotating column 26 rotates, it will drive all the round-headed pins 30 to expand or contract synchronously and equidistantly to both sides. The movable block 29 and the cutting blade 31 follow the round-headed pins 30 to perform synchronous actions, thereby achieving precise control of the length of the yam diced and segmented cuts.

[0027] A method for processing yam food includes the following steps: Step 1: First, place the yam to be processed on the roller conveyor 2 through the feed port 22, start the roller conveyor 2 to transport the yam into the shell 3, and keep it moving on the roller conveyor 2. Step 2: Start the DC motor 15, and use the synchronous pulley 13 and synchronous belt 14 to drive the two movable shafts 4 and the transmission shaft 11 to rotate. The movable shafts 4 drive all the grinding wheels 5 to rotate, and rub the outer surface of the yam to peel it. Step 3: Turn on the delivery pump 18 to pump out the cleaning water in the return water tank 16 and send it into each cleaning tank 7 through the water supply pipe 19, multi-port pipe 20 and branch pipe 21. Then, the rotating drive shaft 11, the driving bevel gear 12 and the driven bevel gear 10 drive all the multi-blade brush plates 9 to rotate at high speed, which disperses the clean water into fine water droplets. These fine water droplets mix with air to form a high-speed water vapor fluid, which powerfully scrubs the surface of the yam to remove the residual outer skin and dirt. The wastewater generated from the cleaning is returned to the return water tank 16 for recycling after passing through the filter screen 17. Step 4: After peeling and cleaning, the yams are fed onto the belt conveyor 23 via the roller conveyor 2 for further transport. At this time, the hydraulic cylinder 32 is activated, which drives the movable support 25 to descend, thereby lowering all the cutting blades 31 to dice or cut the yams. Finally, the yams are discharged from the other end of the belt conveyor 23.
