Description

Technical Field

[0001] This application relates to the field of grain food cooking and processing equipment, and in particular to whole grain food cooking devices. Background Technology

[0002] Whole grain foods refer to various foods processed from grains as the main raw material. Common examples include: instant oatmeal, mixed grain powder, whole wheat steamed buns / bread / noodles, oat rice, multigrain rice, grain bars, brown rice cakes, and cookies. Whole grain foods retain the natural nutrients of the grain's endosperm, germ, bran, and aleurone layer, and are characterized by high dietary fiber, low fat, low saturated fatty acids, low cholesterol, and low calories.

[0003] Currently, whole grain food cooking equipment is a device specifically designed for cooking whole grain foods. It mainly includes: a frame, a steam generator (the core component for generating steam), various steam pipelines connected to the steam generator, a cooking chamber for holding and cooking the grains, a stirring device for stirring the grains during the cooking process, a feeding mechanism for feeding the grains to be cooked into the inlet of the cooking chamber, a discharging mechanism located at the outlet of the cooking chamber, a continuous mesh belt conveyor located inside the cooking chamber that carries the grains and conveys them from the inlet to the outlet, and also includes temperature sensors and pressure sensors for monitoring and controlling the temperature and pressure during the cooking process. When processing grains using a whole grain food cooking device, the whole grain food to be cooked is first fed into the inlet of the cooking chamber through the feeding mechanism. Then, a continuous mesh belt conveyor evenly distributes the grains inside the cooking chamber. Subsequently, the steam generator starts working, generating high-temperature steam. The steam is transported into the cooking chamber through various steam pipelines to provide a heat source for the grain cooking. At the same time, during the cooking process, in order to ensure that the grains are heated evenly and to avoid local overheating or insufficient cooking, the stirring device continuously stirs and turns the grains. When the grains reach the predetermined cooking state, the cooked grains are discharged from the outlet of the cooking chamber and sent to the next processing step by the discharge mechanism.

[0004] When the grain needs to be replaced for cooking or when the next round of grain cooking is to begin, residual grain food will adhere to the chain plate mesh belt used to transport the grain in the continuous mesh belt conveyor. In order to prevent the adhered residual grain food from affecting the subsequent food to be processed, the surface of the chain plate mesh belt needs to be wiped and cleaned. However, cleaning a large area of ​​mesh belt surface is a complex and tedious task. Especially for highly viscous residual grain food, after it has hardened, the cleaning work is not only particularly laborious and inefficient, but also difficult to clean completely. Summary of the Invention

[0005] In order to quickly clean the surface of the chain conveyor belt after the grain food is cooked, thereby improving cleaning efficiency and quality, this application provides a whole grain food cooking device.

[0006] The whole grain food cooking apparatus provided in this application adopts the following technical solution:

[0007] Whole grain food cooking equipment includes:

[0008] The frame includes a cooking chamber, which has an inlet and an outlet on both sides along its length. It also includes a steam generator on the cooking chamber, a steam pipeline connected to the steam generator, a feeding mechanism on the inlet side, a discharging mechanism on the outlet side, a stirring device and a continuous mesh belt conveyor inside the cooking chamber.

[0009] A cleaning mechanism is installed between the chain plate mesh belt and the frame in a continuous mesh belt conveyor. The cleaning mechanism includes a scraping and spraying assembly for forcefully scraping off residual grain food on the chain plate mesh belt, and a rinsing and wiping assembly for rinsing the surface of the chain plate mesh belt.

[0010] By adopting the above technical solution, when the whole grain food is cooked using the whole grain food cooking device, the whole grain food to be cooked is first fed into the inlet of the cooking chamber through the feeding mechanism. Then, the steam generator is started to generate high-temperature steam. The steam is evenly distributed into the cooking chamber through the steam pipeline to provide a heat source for cooking the grain food. At the same time, the stirring device stirs the grain food to ensure that the grain food is heated evenly and to avoid local overheating or insufficient cooking, thereby improving the cooking effect. When the grain reaches the predetermined cooking state, the continuous mesh belt conveyor transports the cooked grain from the outlet of the cooking chamber. The feed outlet discharges the grains, and the discharge mechanism is responsible for sending the grains to the next processing step. After the grain food is cooked, there will be grain food residue on the chain plate mesh belt. At this time, the staff will activate the cleaning mechanism. The scraping and spraying component can powerfully scrape off the hardened grain food residue on the chain plate mesh belt, and the rinsing and wiping component can rinse the surface of the chain plate mesh belt to further remove residues and ensure the cleanliness of the chain plate mesh belt surface. In this way, the cleaning mechanism not only reduces the time and labor intensity of manual cleaning and ensures food safety and hygiene, but also can quickly clean the surface of the chain plate mesh belt, improving cleaning efficiency and cleaning quality.

[0011] Optionally, the scraper assembly includes:

[0012] A forward winding roller assembly is rotatably connected to the frame. Multiple traction ropes are wound on the forward winding roller assembly, and a drive motor is provided between one end of the forward winding roller assembly and the frame.

[0013] A reverse winding roller assembly is rotatably connected to the frame and a bevel gear assembly is provided between it and the forward winding roller assembly. The end of the traction rope away from the forward winding roller assembly is wound onto the reverse winding roller assembly. The winding directions of the traction rope on the forward winding roller assembly and the traction rope on the reverse winding roller assembly are opposite.

[0014] The tensioning component is located between the traction rope and the frame and is used to tension multiple traction ropes.

[0015] The traction rope is arranged in a serpentine pattern. The frame is slidably connected with a scraper and an air jet device in the horizontal direction. The scraper and the air jet device are detachably connected to multiple traction ropes. The scraper is located on the traction rope closer to the forward winding roller group than the air jet device. The scraper and the air jet device move synchronously in opposite directions. The air jet device is connected to an external air source. The scraper abuts against the outside of the chain plate mesh belt.

[0016] By adopting the above technical solution, when scraping off residual or hardened grain food from the chain conveyor belt using the scraper-spray assembly, the drive motor is first started. The drive motor then rotates the forward winding roller assembly. Since the forward and reverse winding roller assemblies are connected by a bevel gear set, the rotation of the forward winding roller assembly is transmitted to the reverse winding roller assembly through the bevel gear set. However, because their winding directions are opposite, the traction ropes on the forward and reverse winding roller assemblies can move synchronously in opposite directions. As the forward and reverse winding roller assemblies rotate, the traction ropes wound on them begin to move. Because the traction ropes are arranged in a serpentine pattern and are fixedly connected to the scraper and air jet device, the movement of the traction ropes causes the scraper and air jet device to move synchronously along the width direction of the chain conveyor belt. During the movement of the scraper... The cleaning mechanism, positioned against the outer side of the chain-type mesh belt, scrapes away residual grains and food products. Simultaneously, a jetting device sprays high-pressure gas onto the belt surface, blowing away the scraped residue and improving cleaning efficiency. During the cleaning process, a tensioning component ensures the traction ropes maintain appropriate tension, preventing slackness during movement and ensuring the cleaning effectiveness of the scraper and jetting device. Furthermore, the entire cleaning process utilizes only a single drive motor as a power source, reducing energy consumption and cost. The synchronous, counter-clockwise movement of the scraper and jetting device, combined with physical scraping and high-pressure gas spraying, efficiently removes residue from the chain-type mesh belt, enhancing cleaning efficiency. Additionally, a bevel gear system maintains appropriate spacing between the multiple traction ropes, preventing interference and improving the stability of the cleaning mechanism.

[0017] Optionally, the tensioning component includes:

[0018] Tensioning bracket, installed on the machine frame;

[0019] Multiple tensioning rollers are rotatably connected to a tensioning bracket. Each of the multiple tensioning rollers corresponds to a multiple traction rope, and the traction ropes are wound around the outside of the tensioning rollers.

[0020] Multiple damping telescopic rods are fixed between the tensioning bracket and the frame;

[0021] A tension spring is fitted onto the outside of the damping telescopic rod, and the tension spring provides appropriate tension to the traction rope.

[0022] By adopting the above technical solution, the tensioning component is used to stabilize the tension of the traction rope during the cleaning process, ensure close contact between the scraper and the air gun and the chain plate mesh belt, improve cleaning efficiency, ensure the continuity and consistency of the cleaning process, and avoid the decrease in cleaning effect or equipment damage caused by insufficient or excessive tension. At the same time, multiple tensioning rollers in the tensioning component drive multiple traction ropes to move synchronously, making it difficult for relative movement to occur between multiple traction ropes.

[0023] Optionally, guide rollers are provided at the serpentine corners of the traction rope, the guide rollers are fixed to the frame, and the traction rope is wound around the outside of the guide rollers.

[0024] By adopting the above technical solution, the guide roller evenly distributes the stress of the traction rope at the corner, avoiding excessive wear or damage to the traction rope due to stress concentration, and extending the service life of the traction rope; in addition, the use of the guide roller reduces the direct contact between the traction rope and the frame, reduces friction, makes the traction rope move more smoothly, reduces energy loss, and improves the operating efficiency of the cleaning mechanism.

[0025] Optionally, the rinsing and wiping assembly includes:

[0026] A water spraying device is slidably connected to the frame in a horizontal direction. The water spraying device and multiple traction ropes can be detachably connected, and the water spraying device is connected to an external water source.

[0027] The wiping bracket is slidably connected to the frame in a horizontal direction. The wiping bracket is detachably connected to multiple traction ropes. The water spraying device is located on the traction rope closer to the air spraying device than the wiping bracket. The top of the wiping bracket is also provided with a receiving groove.

[0028] A flexible absorbent wiping component is disposed in a receiving groove, with the top of the flexible absorbent wiping component extending out of the receiving groove and abutting against the outside of the chain plate mesh belt;

[0029] The self-replaceable component is located on the wiping bracket and is used to replace the flexible absorbent wiping part;

[0030] The self-draining component is located on the wiping bracket and below the receiving groove to drain the water adsorbed in the flexible absorbent wiping element.

[0031] By adopting the above technical solution, when cleaning the surface of the chain conveyor belt using the rinsing and wiping assembly, firstly, as the traction rope moves, the water spraying device slides along the width direction of the chain conveyor belt, spraying water onto the surface of the chain conveyor belt to rinse it; simultaneously, the top of the flexible absorbent wiping component extends out from the top of the receiving groove and abuts against the outside of the chain conveyor belt. As the wiping bracket moves, the flexible absorbent wiping component slides on the chain conveyor belt, absorbing and wiping away residual moisture. When the flexible absorbent wiping component reaches or is close to saturation, the self-draining component automatically discharges the water absorbed by the flexible absorbent wiping component, maintaining the subsequent water absorption performance of the flexible absorbent wiping component; the flexible absorbent wiping component is a consumable part, and it will gradually wear down during the wiping and moving process. When the flexible absorbent wiping component is severely worn, a new flexible absorbent wiping component can be quickly and automatically replaced by a self-replacing component, thereby ensuring the continuity of the cleaning effect.

[0032] Optionally, the self-draining component includes:

[0033] A support plate is slidably connected to a receiving groove along the height direction, and the flexible water-absorbing wiping component abuts against the top of the support plate;

[0034] A compressed electric telescopic rod is installed between the support plate and the wiping bracket, and is located below the support plate;

[0035] A weight sensor, located on the top of the support plate, is used to detect the weight of the flexible absorbent wiping component on the top of the support plate and send a detection signal.

[0036] The controller, connected to the weight sensor and the electric telescopic compression rod, receives detection signals to determine the weight of the flexible absorbent wiping component. When the weight of the flexible absorbent wiping component exceeds a preset weight, the controller sends a control signal to the electric telescopic compression rod. The electric telescopic compression rod then moves the support plate and the flexible absorbent wiping component upwards to squeeze the chain conveyor belt, thereby expelling the water from the flexible absorbent wiping component.

[0037] By adopting the above technical solution, the self-draining component automatically detects and discharges the water adsorbed in the flexible absorbent wiping component to maintain its absorbency. First, a weight sensor continuously monitors the weight of the flexible absorbent wiping component. When the weight of the water adsorbed in the flexible absorbent wiping component increases to a preset weight, the weight sensor detects this change and sends a detection signal to the controller. After receiving the detection signal from the weight sensor, the controller determines whether the weight of the flexible absorbent wiping component exceeds the preset value. Once it is confirmed that it exceeds the preset value, the controller immediately sends a control signal to the compression electric telescopic rod. After receiving the control signal from the controller, the compression electric telescopic rod starts, driving the support plate and the flexible absorbent wiping component on it to move upward, so that the flexible absorbent wiping component is squeezed between the flexible absorbent wiping component and the chain plate mesh belt, thereby squeezing out the water adsorbed in the flexible absorbent wiping component, reducing its weight, and restoring its absorbency. The self-draining component does not require manual intervention and can automatically detect and discharge the water adsorbed in the flexible absorbent wiping component, ensuring the continuous absorbency of the flexible absorbent wiping component.

[0038] Optionally, the self-draining component further includes a plurality of return springs disposed between the support plate and the wiping bracket, the return springs providing a downward pulling force to the support plate.

[0039] By adopting the above technical solution, when the compressed electric telescopic rod drives the bearing plate and flexible water-absorbing wiping parts to move upward and complete the water squeezing and discharge, the return spring can automatically reset the bearing plate to the initial position, preparing for the next drainage action, ensuring the continuous working capacity of the self-draining component, and the return spring gives the bearing plate a downward pulling force, ensuring the stability and balance of the bearing plate during the movement process, reducing the jamming phenomenon caused by uneven force at a single point.

[0040] Optionally, the self-replaceable component includes:

[0041] A replacement chamber is located on one side of the wiping bracket. A top plate is slidably connected to the replacement chamber in the vertical direction. Multiple flexible absorbent wiping components are placed on the top plate from bottom to top.

[0042] A replacement door is hinged to one side of the wiping bracket, and a buckle is provided between the replacement door and the wiping bracket;

[0043] Two opening and closing doors are slidably connected to the top of the wiping bracket in a vertical direction. The top of the wiping bracket has a replacement port and a drain port. The two opening and closing doors are used to block the replacement port and the drain port, respectively.

[0044] The synchronous lifting component is located between the wiping bracket and the two opening and closing doors, and is used to drive the two opening and closing doors to rise and fall synchronously.

[0045] The electric telescopic supply rod is vertically positioned between the replacement chamber and the top plate, and located below the top plate;

[0046] Push-pull electric telescopic rods are installed at intervals along the horizontal direction on one side of the replacement port.

[0047] By adopting the above technical solution, when the flexible absorbent wiping parts are severely worn and affect the cleaning effect, the self-replacing components can automatically replace the flexible absorbent wiping parts to maintain the continuity of the cleaning effect. First, the synchronous lifting components drive the two opening and closing doors to descend synchronously in the vertical direction, opening the replacement port and the drain port to provide a channel for replacing the old and new flexible absorbent wiping parts. Then, the electric telescopic rod moves vertically to push the new flexible absorbent wiping parts on the top plate to the replacement port position. Subsequently, the electric telescopic rod moves horizontally to push the new flexible absorbent wiping parts horizontally and push the severely worn flexible absorbent wiping parts out of the drain port. Then, the synchronous lifting components drive the two opening and closing doors to rise synchronously in the vertical direction again to close the replacement port and the drain port, thus completing the replacement of the old wiping parts. When there are not enough flexible absorbent wiping parts to be replaced in the replacement chamber, the latches on the replacement doors can be released, and then the replacement doors can be opened to add multiple new flexible absorbent wiping parts.

[0048] Optionally, the synchronous lifting component includes:

[0049] Two racks, each rack corresponding to one of the two opening and closing doors, the racks being arranged vertically and fixedly connected to the corresponding opening and closing doors;

[0050] Two drive gears are rotatably connected to the wiping bracket. The two drive gears correspond one-to-one with the two racks. The drive gears mesh with the corresponding racks, and the two racks are located on the same side of the corresponding opening and closing door.

[0051] Each of the two drive gears has a sprocket fixedly mounted on its rotating shaft, and a chain is provided between the two sprockets. A power motor is also provided at the end of the rotating shaft of one of the drive gears.

[0052] By adopting the above technical solution, when it is necessary to open or close the replacement port and the discharge port, the power motor is first started. Then, the power motor drives the two drive gears to rotate synchronously through the sprocket and chain to ensure the consistency of the action. The rotation of the drive gear will drive the rack meshing with it to move in the vertical direction, so that the rack drives the two opening and closing doors to rise and fall synchronously, realizing the opening and closing of the replacement port and the discharge port.

[0053] Optionally, the cleaning mechanism further includes a collection component disposed below the scraping and rinsing assembly and the wiping assembly, the collection component including a water collection tank and a filter plate disposed on top of the water collection tank.

[0054] By adopting the above technical solution, the water collection tank is used to collect grains and water cleaned from the scraping and rinsing components, and the filter plate is used to filter grain residues in the water. By collecting and filtering wastewater, direct discharge of pollutants to the environment is avoided, improving the environmental friendliness of the cleaning process. Moreover, the collected wastewater can be recycled after treatment, such as for the re-cleaning of equipment or as water for other production processes, thus achieving resource conservation and recycling.

[0055] In summary, this application includes at least one of the following beneficial technical effects:

[0056] 1. The cleaning mechanism not only reduces the time and labor intensity of manual cleaning, ensuring food safety and hygiene, but also enables rapid cleaning of the surface of the chain conveyor belt, improving cleaning efficiency and quality;

[0057] 2. In the scraper-spray assembly, on the one hand, only one drive motor is used as the power source throughout the entire cleaning process, reducing the energy consumption and cost of the equipment. On the other hand, the synchronous counter-movement of the scraper and the air jet device, combined with physical scraping and high-pressure gas jetting, can efficiently remove residues on the chain conveyor belt, improving cleaning efficiency. At the same time, the bevel gear set keeps multiple traction ropes at an appropriate distance, avoiding interference between the traction ropes and improving the stability of the cleaning mechanism. Furthermore, the guide roller evenly distributes the stress of the traction ropes at the corners, avoiding excessive wear or damage to the traction ropes due to stress concentration, thus extending the service life of the traction ropes. In addition, the use of guide rollers reduces the direct contact between the traction ropes and the frame, reducing friction and making the traction ropes move more smoothly, reducing energy loss and improving the operating efficiency of the cleaning mechanism.

[0058] 3. The tensioning component is used to ensure the tension of the traction rope is stable during the cleaning process, so that the scraper and air gun are in close contact with the chain plate mesh belt, improving cleaning efficiency, ensuring the continuity and consistency of the cleaning process, and avoiding the decrease in cleaning effect or equipment damage due to insufficient or excessive tension. At the same time, multiple tensioning rollers in the tensioning component drive multiple traction ropes to move synchronously, so that the relative movement between multiple traction ropes is not easy.

[0059] 4. In the rinsing and wiping assembly, when the flexible absorbent wiping element reaches or is close to saturation, the self-draining component automatically drains the water absorbed by the flexible absorbent wiping element, maintaining its subsequent absorbency. The flexible absorbent wiping element is a consumable part and will gradually wear down during wiping and movement. When the wear of the flexible absorbent wiping element is severe, the self-replacement component can quickly and automatically replace it with a new flexible absorbent wiping element, thereby ensuring the continuity of cleaning effect.

[0060] 5. To maintain the absorbency of the flexible absorbent wiper by automatically detecting and draining the water adsorbed in the wiping component through a self-draining component, a weight sensor continuously monitors the weight of the wiping component. When the weight of the wiping component with adsorbed water increases to a preset weight, the weight sensor detects this change and sends a detection signal to the controller. After receiving the detection signal, the controller determines whether the weight of the wiping component exceeds the preset value. Once confirmed, the controller immediately sends a control signal to the compression electric telescopic rod. Upon receiving the control signal, the compression electric telescopic rod starts, moving the support plate and the flexible absorbent wiper on it upwards. This causes the flexible absorbent wiper to be squeezed against the chain conveyor belt, thereby squeezing out the water adsorbed in the wiping component, reducing its weight, and restoring its absorbency. The self-draining component requires no manual intervention and can automatically detect and drain the water adsorbed in the flexible absorbent wiper, ensuring the continuous absorbency of the wiping component.

[0061] 6. When the flexible absorbent wiping element is severely worn and affects the cleaning effect, the self-replacing component automatically replaces the flexible absorbent wiping element to maintain the cleaning effect. First, the synchronous lifting component drives the two opening and closing doors to descend synchronously in the vertical direction, opening the replacement port and the drain port to provide a channel for replacing the old and new flexible absorbent wiping elements. Then, the electric telescopic rod moves vertically to push the new flexible absorbent wiping element on the top plate to the replacement port position. Subsequently, the electric telescopic rod moves horizontally to move the new flexible absorbent wiping element horizontally and pushes the severely worn flexible absorbent wiping element out of the drain port. Then, the synchronous lifting component drives the two opening and closing doors to rise synchronously in the vertical direction again to close the replacement port and the drain port, thus completing the replacement of the old wiping element. When there are not enough flexible absorbent wiping elements to be replaced in the replacement chamber, the latch locking the replacement door can be released, and then the replacement door can be opened to add more new flexible absorbent wiping elements.

[0071] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0072] This application discloses a whole grain food cooking apparatus. (Refer to...) Figure 1 and Figure 2 The whole grain food cooking device includes a frame 1, on which a cooking chamber 2 is mounted. The cooking chamber 2 has a feed inlet 21 and a discharge outlet 22 on both sides along its length. A steam generator 3 and steam pipes connected to the steam generator 3 are mounted on the cooking chamber 2. A feeding mechanism is located on one side of the feed inlet 21, and a discharge mechanism is located on the other side of the discharge outlet 22. A stirring device 4 and a continuous mesh belt conveyor 5 are installed inside the cooking chamber 2.

[0073] Reference Figure 2 and Figure 3 A cleaning mechanism 6 is provided between the chain plate mesh belt 51 and the frame 1 in the continuous mesh belt conveyor 5. The cleaning mechanism 6 includes a scraping and spraying assembly 61, a rinsing and wiping assembly 62, and a collection assembly 63 located below the scraping and spraying assembly 61 and the rinsing and wiping assembly 62. The scraping and spraying assembly 61 is used to forcefully scrape off residual grains and food products on the chain plate mesh belt 51; the rinsing and wiping assembly 62 is used to rinse the surface of the chain plate mesh belt 51. The collection assembly 63 includes a water collection tank 631 and a filter plate 632 located on top of the water collection tank 631; the water collection tank 631 is used to collect the grains and food products and water cleaned from the scraping and spraying assembly 61 and the rinsing and wiping assembly 62, and the filter plate 632 is used to filter grains and food products and other residues in the water. By collecting and filtering wastewater, direct discharge to the environment is avoided, improving the environmental friendliness of the cleaning process. Moreover, the collected wastewater can be recycled after treatment, such as for the re-cleaning of equipment or as water for other production processes, realizing resource conservation and recycling.

[0074] When cooking grains using a whole grain food cooking device, the whole grain food to be cooked is first fed into the inlet 21 of the cooking chamber 2 through the feeding mechanism. Then, the steam generator 3 is activated to generate high-temperature steam, which is evenly distributed into the cooking chamber 2 through steam pipes to provide a heat source for cooking the grain food. Simultaneously, the stirring device 4 stirs the grain food to ensure even heating, avoiding localized overheating or insufficient cooking, thus improving the cooking effect. Once the grains reach the predetermined cooking state, the continuous mesh belt conveyor 5 discharges the cooked grains from the outlet 22 of the cooking chamber 2, and the discharge mechanism is responsible for sending the grains to the next processing step. After the grain food is cooked, some grain food residue remains on the chain plate mesh belt 51. At this time, the cleaning mechanism 6 is activated. The scraper spray component 61 powerfully scrapes off the hardened grain food residue on the chain plate mesh belt 51, and the rinsing and wiping component 62 rinses the surface of the chain plate mesh belt 51 to further remove residue and ensure the cleanliness of the chain plate mesh belt 51 surface. The cleaning mechanism 6 not only reduces the time and labor intensity of manual cleaning, ensuring food safety and hygiene, but also enables rapid cleaning of the surface of the chain conveyor belt 51, improving cleaning efficiency and quality.

[0075] Reference Figure 3 and Figure 4The scraper spray assembly 61 includes a forward winding roller group 611 rotatably connected to the frame 1. Multiple traction ropes 612 are wound on the forward winding roller group 611, and a drive motor 613 is disposed between one end of the forward winding roller group 611 and the frame 1. A reverse winding roller group 614 is rotatably connected to the frame 1. The end of the traction rope 612 away from the forward winding roller group 611 is wound onto the reverse winding roller group 614, and the winding directions of the traction ropes 612 on the forward winding roller group 611 and the reverse winding roller group 614 are opposite. A bevel gear group 615 is also disposed between the reverse winding roller group 614 and the forward winding roller group 611. One bevel gear in the bevel gear group 615 is fixedly sleeved with the forward winding roller group 611, and the other is fixedly sleeved with the reverse winding roller group 614. A tensioning component 616 is provided between the traction rope 612 and the frame 1. The tensioning component 616 is used to tension the multiple traction ropes 612.

[0076] Among them, reference Figure 3 and Figure 4 The traction ropes 612 are arranged in a serpentine pattern, with guide rollers 617 installed at each bend. The guide rollers 617 are fixed to the frame 1, and the traction ropes 612 are wound around their outer sides. The guide rollers 617 evenly distribute the stress of the traction ropes 612 at the bends, preventing excessive wear or damage to the traction ropes 612 due to stress concentration. The use of guide rollers 617 also reduces direct contact between the traction ropes 612 and the frame 1, lowering friction and making the movement of the traction ropes 612 smoother. A scraper 618 and an air jet device 619 are slidably connected to the frame 1 in the horizontal direction. The scraper 618 and air jet device 619 are detachably connected to the multiple traction ropes 612 via bolts and pressure plates. The scraper 618 is positioned closer to the forward winding roller group 611 on the traction rope 612 than the air jet device 619, and the scraper 618 and air jet device 619 move synchronously in opposite directions. The jet device 619 is connected to an external air source, and the scraper 618 abuts against the outside of the chain plate mesh belt 51.

[0077] When scraping residual or hardened grain food on the chain conveyor belt 51 using the scraper spray assembly 61, the drive motor 613 is started first, and then the drive motor 613 drives the forward winding roller assembly 611 to rotate. Since the forward winding roller assembly 611 and the reverse winding roller assembly 614 are connected by a bevel gear assembly 615, the rotation of the forward winding roller assembly 611 is transmitted to the reverse winding roller assembly 614 through the bevel gear assembly 615. However, since the two winding directions are opposite, the traction ropes 612 on the forward winding roller assembly 611 and the reverse winding roller assembly 614 can move synchronously in opposite directions. As the forward winding roller assembly 611 and the reverse winding roller assembly 614 rotate, the traction rope 612 wound on the forward winding roller assembly 611 and the reverse winding roller assembly 614 begins to move. Since the traction rope 612 is arranged in a serpentine pattern and is fixedly connected to the scraper 618 and the air jet device 619, the movement of the traction rope 612 will drive the scraper 618 and the air jet device 619 to move synchronously along the width direction of the chain plate mesh belt 51. During the movement, the scraper 618 abuts against the outside of the chain plate mesh belt 51, scraping off residual grain food on the chain plate mesh belt 51 by contact.

[0078] Simultaneously, the jetting device 619 sprays high-pressure gas onto the surface of the chain conveyor belt 51, blowing away residual grains and food scraped off by the scraper 618, thus improving the cleaning effect. During the cleaning process, the tensioning component 616 ensures that the traction rope 612 maintains appropriate tension, preventing slack during movement and affecting the cleaning effect of the scraper 618 and the jetting device 619. On one hand, only one drive motor 613 is used as the power source throughout the entire cleaning process, reducing the energy consumption and cost of the equipment. On the other hand, the synchronous counter-movement of the scraper 618 and the jetting device 619, combined with physical scraping and high-pressure gas spraying, can efficiently remove residues on the chain conveyor belt 51, improving cleaning efficiency. At the same time, the bevel gear set 615 maintains an appropriate spacing between the multiple traction ropes 612, avoiding interference between the traction ropes 612 and improving the stability of the cleaning mechanism 6 operation.

[0079] Reference Figure 4 and Figure 5 The tensioning component 616 includes a tensioning bracket 6161 disposed on one side of the frame 1. Multiple tensioning rollers 6162 are rotatably connected to the tensioning bracket 6161. Each tensioning roller 6162 corresponds to a specific traction rope 612, and the traction ropes 612 are wound around the outside of the tensioning rollers 6162. Multiple damping telescopic rods 6163 are fixed between the tensioning bracket 6161 and the frame 1. Tensioning springs 6164 are sleeved on the outside of each damping telescopic rod 6163, and the tensioning springs 6164 are used to provide appropriate tension to the traction ropes 612.

[0080] The tensioning component 616 is used to ensure the tension of the traction rope 612 is stable during the cleaning process, so that the scraper 618 and the air gun are in close contact with the chain plate mesh belt 51, thereby improving cleaning efficiency and ensuring the continuity and consistency of the cleaning process. This avoids a decrease in cleaning effect or equipment damage due to insufficient or excessive tension. At the same time, the multiple tensioning rollers 6162 in the tensioning component 616 drive the multiple traction ropes 612 to move synchronously, making it difficult for the multiple traction ropes 612 to move relative to each other.

[0081] Reference Figure 6 and Figure 7 The rinsing and wiping assembly 62 includes a water spraying device 621 slidably connected to the frame 1 in a horizontal direction. The water spraying device 621 and multiple traction ropes 612 are detachably connected by bolts and pressure plates, and the water spraying device 621 is connected to an external water source. A wiping bracket 622 is slidably connected to the frame 1 in a horizontal direction. The wiping bracket 622 and multiple traction ropes 612 are detachably connected by bolts and pressure plates, and the water spraying device 621 is located on the traction ropes 612 closer to the air spraying device 619. The top of the wiping bracket 622 is also provided with a receiving groove 6221; a flexible water-absorbing wiping element 623 is provided in the receiving groove 6221. The top of the flexible water-absorbing wiping element 623 extends out of the receiving groove 6221 and abuts against the outside of the chain plate mesh belt 51. The flexible water-absorbing wiping element 623 is made of microfiber material, which has good water absorption and wear resistance. The wiping bracket 622 is equipped with a self-replacing component 624, which is used to replace the flexible absorbent wiping element 623. The wiping bracket 622 is also equipped with a self-draining component 625, which is located below the receiving groove 6221 and is used to drain the water adsorbed in the flexible absorbent wiping element 623.

[0082] When the surface of the chain conveyor belt 51 is cleaned by the rinsing and wiping assembly 62, the water spraying device 621 first slides along the width direction of the chain conveyor belt 51 as the traction rope 612 moves, spraying water onto the surface of the chain conveyor belt 51 to rinse it. Simultaneously, the top of the flexible absorbent wiping member 623 extends out from the top of the receiving groove 6221 and abuts against the outside of the chain conveyor belt 51. As the wiping bracket 622 moves, the flexible absorbent wiping member 623 slides on the chain conveyor belt 51, absorbing and wiping away residual moisture. When the flexible absorbent wiping member 623 reaches or is close to saturation, the self-draining component 625 automatically discharges the absorbed water from the flexible absorbent wiping member 623, maintaining its subsequent absorbency. The flexible absorbent wiping component 623 is a consumable part. During the wiping and moving process, the flexible absorbent wiping component 623 will gradually wear down. When the flexible absorbent wiping component 623 is worn down, the self-replacing component 624 can quickly and automatically replace it with a new flexible absorbent wiping component 623, thereby ensuring the continuity of the cleaning effect.

[0083] Reference Figure 6 and Figure 7 The self-draining component 625 includes a support plate 6251 slidably connected to a receiving groove 6221 along its height direction, and a flexible absorbent wiping member 623 abutting against the support plate 6251. A compression-operated electric telescopic rod 6252 is provided between the support plate 6251 and the wiping bracket 622, and the compression-operated electric telescopic rod 6252 is located below the support plate 6251. A plurality of return springs 6253 are provided between the support plate 6251 and the wiping bracket 622, and the return springs 6253 provide a downward pulling force to the support plate 6251. A weight sensor is provided on the top of the support plate 6251, which is used to detect the weight of the flexible absorbent wiping member 623 on the top of the support plate 6251 and send a detection signal. The self-draining component 625 also includes a controller connected to a weight sensor and a compression electric telescopic rod 6252. The controller receives detection signals to determine the weight of the flexible absorbent wiping component 623. When the weight of the flexible absorbent wiping component 623 is greater than a preset weight, the controller sends a control signal to the compression electric telescopic rod 6252. The compression electric telescopic rod 6252 drives the support plate 6251 and the flexible absorbent wiping component 623 to move upward and squeeze the chain plate mesh belt 51 to squeeze out the water in the flexible absorbent wiping component 623.

[0084] To maintain its absorbency, the flexible absorbent wiping element 623 automatically detects and drains the water absorbed by the self-draining component 625. First, a weight sensor continuously monitors the weight of the flexible absorbent wiping element 623. When the weight of the water absorbed by the flexible absorbent wiping element 623 increases to a preset weight, the weight sensor detects this change and sends a detection signal to the controller. Upon receiving the detection signal, the controller determines whether the weight of the flexible absorbent wiping element 623 exceeds the preset value. If it is confirmed to exceed the preset value, the controller immediately sends a control signal to the compression electric telescopic rod 6252. Upon receiving the control signal, the compression electric telescopic rod 6252 starts, moving the support plate 6251 and the flexible absorbent wiping element 623 upwards. This causes compression between the flexible absorbent wiping element 623 and the chain-plate mesh belt 51, squeezing out the water absorbed by the flexible absorbent wiping element 623, reducing its weight, and restoring its absorbency.

[0085] When the compressed electric telescopic rod 6252 moves the support plate 6251 and the flexible absorbent wiping component 623 upwards, completing the water squeezing and discharge, the return spring 6253 automatically returns the support plate 6251 to its initial position, preparing for the next drainage action and ensuring the continuous working capability of the self-draining component 625. Furthermore, the return spring 6253 applies a downward pulling force to the support plate 6251, ensuring its stability and balance during movement and reducing jamming caused by uneven force at a single point. The self-draining component 625 requires no manual intervention, automatically detecting and discharging the water absorbed by the flexible absorbent wiping component 623, ensuring its continuous water absorption performance.

[0086] Reference Figure 7 and Figure 8 The self-replacing component 624 includes a replacement chamber 6241 disposed on one side of the wiping bracket 622. A top plate 6242 is slidably connected to the replacement chamber 6241 in a vertical direction. Multiple flexible absorbent wiping elements 623 are placed on the top plate 6242 from bottom to top. A replacement door 6243 is hinged to one side of the wiping bracket 622, and a buckle 6244 is provided between the replacement door 6243 and the wiping bracket 622. Two parallel and spaced-apart opening and closing doors 6245 are slidably connected to the top of the wiping bracket 622 in a vertical direction. The top of the wiping bracket 622 has a replacement port 6222 and a drain port 6223. The two opening and closing doors 6245 are used to block the replacement port 6222 and the drain port 6223, respectively. A synchronous lifting component 626 is provided between the wiping bracket 622 and the two opening and closing doors 6245, and the synchronous lifting component 626 is used to drive the two opening and closing doors 6245 to rise and fall synchronously. A replenishment electric telescopic rod 6246 is vertically installed between the replacement chamber 6241 and the top plate 6242, and the replenishment electric telescopic rod 6246 is located below the top plate 6242. A push-pull electric telescopic rod 6247 is horizontally spaced on one side of the replacement port 6222.

[0087] When the flexible absorbent wiping element 623 is severely worn, affecting the cleaning effect, the self-replacing component 624 automatically replaces the flexible absorbent wiping element 623 to maintain the continuous cleaning effect. First, the synchronous lifting component 626 drives the two opening and closing doors 6245 to descend synchronously in the vertical direction, opening the replacement port 6222 and the discharge port 6223, providing a channel for the replacement of the old and new flexible absorbent wiping elements 623. Next, the supply electric telescopic rod 6246 moves vertically, pushing the new flexible absorbent wiping element 623 on the top plate 6242 to the position of the replacement port 6222. Then, the push-pull electric telescopic rod 6247 moves horizontally, pushing the new flexible absorbent wiping element 623 horizontally and pushing the severely worn flexible absorbent wiping element 623 out of the discharge port 6223. Then, the synchronous lifting component 626 drives the two opening and closing doors 6245 to rise synchronously in the vertical direction again, closing the replacement port 6222 and the discharge port 6223, thus completing the replacement of the old wiping element. When there are not enough flexible absorbent wipes 623 to be replaced in the replacement chamber 6241, the latch 6244 can be released from locking the replacement door 6243, and then the replacement door 6243 can be opened to add more new flexible absorbent wipes 623.

[0088] Reference Figure 7 and Figure 8 The synchronous lifting component 626 includes two racks 6261 respectively fixed on two opening and closing doors 6245. The racks 6261 are arranged vertically, and both racks 6261 are located on the same side of the opening and closing doors 6245. Two drive gears 6262 are rotatably connected to the wiping bracket 622. The two drive gears 6262 correspond one-to-one with the two racks 6261, and the drive gears 6262 mesh with the corresponding racks 6261. A sprocket 6263 is fixedly sleeved on the rotating shaft of each of the two drive gears 6262, and a chain 6264 is arranged between the two sprockets 6263. A power motor 6265 is also provided at the end of the rotating shaft of one of the drive gears 6262.

[0089] When it is necessary to open or close the replacement port 6222 and the discharge port 6223, the power motor 6265 is started first. Then, the power motor 6265 drives the two drive gears 6262 to rotate synchronously through the sprocket 6263 and the chain 6264 to ensure the consistency of the action. The rotation of the drive gear 6262 will drive the rack 6261 meshing with it to move in the vertical direction. Thus, the rack 6261 drives the two opening and closing doors 6245 to rise and fall synchronously, realizing the opening and closing of the replacement port 6222 and the discharge port 6223.

[0090] The implementation principle of the whole grain food cooking device in this application embodiment is as follows: When cooking grains using the whole grain food cooking device, the whole grain food to be cooked is first fed into the inlet 21 of the cooking chamber 2 through the feeding mechanism. Then, the steam generator 3 is started to generate high-temperature steam, which is evenly distributed into the cooking chamber 2 through the steam pipeline to provide a heat source for cooking the grain food. At the same time, the stirring device 4 stirs the grain food to ensure that the grain food is heated evenly, avoiding local overheating or insufficient cooking, and improving the cooking effect. When the grain reaches the predetermined cooking state, the continuous mesh belt conveyor 5 discharges the cooked grain from the outlet 22 of the cooking chamber 2, and the discharge mechanism is responsible for sending the grain to the next processing step. After the grain food is cooked, grain food residue will remain on the conveyor belt 51. At this time, the cleaning mechanism 6 is activated. The scraper spray component 61 can powerfully scrape off the hardened grain food residue on the conveyor belt 51, and the rinsing and wiping component 62 can rinse the surface of the conveyor belt 51 to further remove residue and ensure the cleanliness of the surface of the conveyor belt 51. The cleaning mechanism 6 not only reduces the time and labor intensity of manual cleaning, ensuring food safety and hygiene, but also allows for rapid cleaning of the surface of the conveyor belt 51, improving cleaning efficiency and quality.

[0091] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
