Description

Technical Field

[0001] This invention relates to the field of pre-prepared food processing technology, specifically to a pre-prepared food preservation production device and method. Background Technology

[0002] Pre-cooked food preservation production equipment is key to ensuring the freshness and extended shelf life of pre-cooked food during production. This equipment includes cleaning and sterilization equipment, processing equipment, and packaging equipment. The cleaning and sterilization equipment includes bubble washing machines and ultraviolet sterilization equipment. Vegetable cleaning, as a crucial initial step, directly affects the quality and shelf life of the finished pre-cooked food. Bubble washing machines are widely used in the field of vegetable primary processing due to their relatively high cleaning efficiency and controllable cost.

[0003] Traditional bubble washing machines rely on an air pump to continuously blow air into the washing tank, causing a large number of bubbles to rise in the water. At the same time, a circulating water pump drives the water flow. The bubbles and water flow work together to make the vegetables roll and rub against each other in the washing tank. This method can indeed remove some loose dirt, dust and other impurities from the surface of vegetables to a certain extent.

[0004] The existing bubble cleaning machine mainly operates by using an air pump to generate a large number of bubbles, which, together with a circulating water pump, causes the water to circulate and surge. This allows the vegetables to tumble, collide, and rub against each other in the water tank under the action of the water flow and bubbles. However, this cleaning method is not very effective, as it is difficult to effectively remove tightly attached dirt of various types. Pesticide residues on the surface of vegetables are difficult to remove by the impact of the bubble water flow due to chemical bonds. Furthermore, stubborn dirt in hidden places such as deep folds and root joints can also avoid the cleaning effect of the water flow and bubbles. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a pre-prepared vegetable preservation production device and method to solve the technical problem that the existing bubble washing machine, which uses an air pump to blow air and a circulating water pump to drive water to make vegetables roll and rub in the water tank for cleaning, is not effective in cleaning tightly attached dirt of different properties, pesticide residues on the surface of vegetables, and stubborn mud in hidden parts.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pre-prepared vegetable preservation production device, comprising a main body, a conveying mechanism disposed at the bottom of the main body, and a washing mechanism disposed above the conveying mechanism inside the main body;

[0007] The conveying mechanism includes a conveyor belt, two sets of conveyor rollers, and a rotating shaft. The conveyor belt is wound around the outside of the two sets of conveyor rollers, and the two sets of conveyor rollers are rotatably connected to the main body via the rotating shaft. The surface of the conveyor belt is provided with drainage holes, and multiple sets of baffles are evenly arranged on the surface of the conveyor belt. The washing mechanism includes a transmission roller, a cross transmission shaft, a transmission belt, and brushes. The two sets of transmission rollers are connected to the main body via the cross transmission shaft, and the transmission rollers and the cross transmission shaft are radially limited and axially sliding connected. The two sets of transmission belts are wound around the outside of the two sets of transmission rollers, and multiple sets of brushes are evenly distributed and fixed on the outside of the two sets of transmission belts.

[0008] The washing mechanism also includes a drive plate, a movable frame, a slider, a reciprocating lead screw, and a drive rod. The two sets of drive plates are located outside the two sets of transmission belts, and the movable frame is fixed on the top of the two sets of drive plates. The slider is fixed at the middle position on the top of the movable frame. The reciprocating lead screw passes through the slider and is connected to the main body through the drive rod. The washing mechanism also includes guide rods. The two sets of guide rods pass through the movable frame and are fixedly connected to the inner wall of the main body on both sides. The guide rods and the movable frame are slidably connected.

[0009] A transmission mechanism is provided on one side of the main body. The transmission mechanism includes a connecting gear, a steering gear, a transmission gear, a coaxial gear, and a drive gear. The connecting gear is fixed to the outside of one set of rotating shafts. The steering gear is movably connected to one side of the main body and meshes with the connecting gear. One set of transmission gears and coaxial gears is fixed to the outside of one set of cross transmission shafts. Transmission gears are fixed to the outside of both sets of cross transmission shafts. The drive gear is fixed to the outside of one set of drive rods. A transmission hole is opened inside one set of rotating shafts. The transmission hole is fixedly connected to the output end of an external drive motor.

[0010] The transmission mechanism also includes a first synchronous belt and a second synchronous belt. The steering gear and the coaxial gear are connected by the first synchronous belt, and the two sets of transmission gears and drive gears are connected by the second synchronous belt.

[0011] The washing mechanism also includes bearings and slip rings. The cross drive shaft and the main body are rotatably connected by bearings, and the drive plate and the cross drive shaft are slidably connected by slip rings. The slip rings and the cross drive shaft are axially sliding and radially rotating connected.

[0012] The main body is equipped with a rinsing mechanism, which includes a main water spray pipe, a branch water spray pipe, and a nozzle module. The main water spray pipe is fixed to one side of the main body, and multiple sets of branch water spray pipes extend through the washing mechanism inside the main body. The branch water spray pipes are connected to the main water spray pipe, and multiple nozzle modules are inclinedly installed at one end of each branch water spray pipe. The drive plate has through holes, and the opening of the through holes will not affect the blocking effect of the washing mechanism on the nozzle modules during the reciprocating washing action.

[0013] The rinsing mechanism also includes a return box, a water storage chamber, a suction pipe, a water pump module, and a water outlet pipe. The return box is located at one end of the main body, and the water storage chamber inside the return box is connected to the interior of the main body. The water pump module is installed at the bottom of one end of the main body, and the water inlet of the water pump module is connected to the return box through the suction pipe. The water outlet of the water pump module is connected to the main spray pipe through the water outlet pipe.

[0014] A bubble generating mechanism is provided at the bottom outer side of the main body. The bubble generating mechanism includes an air pump module, a jet main pipe, jet branch pipes and a sealing ring. The jet main pipe is connected to the air outlet of the air pump module. Multiple sets of jet branch pipes extending to the bottom inner side of the main body are evenly fixed inside the jet main pipe, and a sealing ring is provided between each set of jet branch pipes and the main body.

[0015] The main body is fixedly connected to a discharge conveying module at one end, and the discharge conveying module is set at an angle.

[0016] By adopting the above technical solution, the vegetables are cleaned from multiple angles through the reverse operation of the washing mechanism, the reciprocating washing mechanism, the pressurized water flow of the rinsing mechanism, and the bubble generation mechanism. This effectively removes various types of dirt and pesticide residues, significantly improving the cleaning effect, ensuring the cleanliness of the raw materials for pre-prepared vegetables, and facilitating freshness. The transmission mechanism rationally distributes and converts power, ensuring efficient and stable operation of all components. The system is highly automated. The rinsing mechanism's nozzles rinse from multiple angles, and water is recycled through a return box and filter plate, saving water and avoiding secondary pollution from sludge. This reduces costs and is environmentally friendly. The ingenious design of each component, such as the baffles and drainage holes of the conveying mechanism to ensure stable conveying, and the guide rods and bearings of the washing mechanism to ensure smooth and precise movement, improves the overall reliability and lifespan of the device. This provides an efficient, environmentally friendly, and reliable solution for the production and preservation of pre-prepared vegetables, and powerfully promotes the high-quality development of the pre-prepared vegetable industry.

[0017] Furthermore, the rinsing mechanism also includes a support plate and a filter plate. The support plate is located inside the return box and is slidably connected to it, and multiple sets of inclined filter plates are evenly fixed at one end of the support plate.

[0018] By adopting the above technical solution, a cover plate is provided on the top of the return box. The cover plate and the return box are movably connected. By opening the cover plate, the support plate and the filter plate can be taken out as a whole through the groove on the top of the support plate for cleaning, thereby improving the filtration efficiency. When the filter plate needs to be cleaned, the cover plate on the top of the return box is opened, and the support plate and the filter plate can be taken out as a whole for cleaning through the groove on the top of the support plate, thereby improving the filtration efficiency and ensuring the long-term stable operation of the rinsing mechanism.

[0019] Furthermore, a bottom support frame is provided at the bottom of the main body.

[0020] By adopting the above technical solution, the bottom support frame is located at the bottom of the main body, which plays the role of supporting the main body and the entire device, ensuring the stability of the device during operation, and enabling it to be placed stably on the ground or workbench.

[0021] A method for using a pre-prepared food preservation production device, the process of which includes the following steps:

[0022] S1: Vegetable conveying: Start the external drive motor to drive the conveyor roller to rotate, and then the conveyor belt will convey the vegetables. The vegetables enter the equipment from the top of the conveyor mechanism. The discharge conveying module can be driven by a separate drive motor or by connecting the conveyor roller through a belt. It is ready to receive the washed vegetables at the end of the main body.

[0023] S2: Cleaning process:

[0024] Brush washing and rinsing in tandem: When vegetables enter the washing mechanism, multiple sets of brushes in the washing mechanism run in the opposite direction under the action of the transmission belt, washing the vegetables in the opposite direction and reducing their running speed on the conveyor belt, increasing the washing time and improving the washing effect. At the same time, multiple sets of nozzle modules in the rinsing mechanism spray pressurized water onto the vegetables to rinse off the mud on their surface.

[0025] Enhanced washing effect by reciprocating brush: Through the transmission mechanism, the drive rod drives the reciprocating screw to rotate, which in turn drives the slider to move back and forth. The slider drives the transmission roller, transmission belt and brush to move back and forth along the cross transmission shaft axially through the moving frame and drive plate, so that the brush can wash the vegetables back and forth while running in the opposite direction.

[0026] Bubble-assisted cleaning: The bubble generating equipment injects gas into the water inside the main body through the air pump module, the main jet pipe and the jet branch pipe to form bubbles, which makes the vegetables roll and rub against each other in the cleaning tank, further improving the cleaning effect.

[0027] S3: Water circulation and sludge treatment:

[0028] Sludge flows to the return box with the water: Because the nozzle module is angled toward the feed end of the conveying mechanism, the water in the main body flows toward the return box under the action of the flushing water flow, and the sludge washed off enters the return box with the water flow.

[0029] Filtration and Recycling: Multiple filter plates in the return box filter the sludge. The filtered water enters the water storage chamber and is drawn in by the water pump module. It then enters the water spray branch pipe through the suction pipe, the outlet pipe, and the main spray pipe. Finally, it is sprayed onto the surface of the vegetables through the nozzle module to achieve circulating rinsing. At the same time, during the reverse operation of the brush, the nozzle module can spray some water onto the brush to rinse the sludge trapped inside.

[0030] S4: Cleaning complete: The cleaned vegetables are sent out by the discharge conveyor module, completing the entire cleaning process.

[0031] In summary, the present invention has the following beneficial effects: The invention utilizes the reverse operation of the washing mechanism, the pressurized water flow of the reciprocating washing mechanism, and the bubble generation mechanism to clean vegetables from multiple angles, effectively removing various types of dirt and pesticide residues, significantly improving the cleaning effect, ensuring the cleanliness of pre-prepared vegetable raw materials, and facilitating freshness. The transmission mechanism rationally distributes and converts power, ensuring efficient and stable operation of all components, resulting in a high degree of automation. The rinsing mechanism's nozzles provide multi-angle rinsing, and water is recycled through a return box and filter plate, saving water and avoiding secondary pollution from sludge, reducing costs and being environmentally friendly. The ingenious design of each component, such as the baffles and drainage holes of the conveying mechanism ensuring stable conveying, and the guide rods and bearings of the washing mechanism ensuring smooth and precise movement, improves the overall reliability and lifespan of the device, providing an efficient, environmentally friendly, and reliable solution for pre-prepared vegetable preservation production, and powerfully promoting the high-quality development of the pre-prepared vegetable industry.

Detailed Implementation

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0048] The embodiments of the present invention will now be described.

[0049] Example 1

[0050] A pre-prepared food preservation production device and method, such as Figure 1-14 As shown, it includes a main body 1, a conveying mechanism 2, a washing mechanism 3, a transmission mechanism 4, a rinsing mechanism 5, a bubble generating mechanism 6, a bottom support frame 7, and a discharge conveying module 8;

[0051] The main body 1 is the outer shell of the entire preservation production device, which houses other components and provides a space for the cleaning and preservation of pre-cooked vegetables. The bottom support frame 7 is located at the bottom of the main body 1 and serves to support the main body 1 and the entire device, ensuring the stability of the device during operation and allowing it to be placed stably on the ground or workbench.

[0052] The conveying mechanism 2 includes a conveyor belt 201, two sets of conveying rollers 202 and a rotating shaft 203. The conveyor belt 201 is wrapped around the outside of the two sets of conveying rollers 202 to form a circulating conveying channel. The two sets of conveying rollers 202 and the main body 1 are rotatably connected by the rotating shaft 203, so that the conveying rollers 202 can rotate flexibly on the main body 1.

[0053] One set of rotating shafts 203 has a transmission hole 204 inside, which is used to connect with the output end of an external drive motor to receive power. The surface of the conveyor belt 201 has a drainage hole 205 to facilitate the discharge of wastewater during the washing process. Multiple sets of baffles 206 are evenly arranged on the surface of the conveyor belt 201. These baffles 206 can prevent vegetables from slipping during the conveying process and ensure that the vegetables can move stably on the conveyor belt.

[0054] Specifically, when the external drive motor starts, its output shaft drives one set of conveyor rollers 202 to rotate through the connection with the transmission hole 204. Since the conveyor belt 201 is wrapped around the two sets of conveyor rollers 202, the rotation of the conveyor rollers 202 will cause the conveyor belt 201 to move accordingly, thereby realizing the conveying of vegetables.

[0055] Vegetables enter the equipment from the top of the conveyor 2. The conveyor belt 201 transports the vegetables smoothly to the washing mechanism 3 below for cleaning. The presence of the drain hole 205 allows the water sprayed by the nozzle module 510 and the water remaining on the vegetables to be discharged in time during the cleaning process, preventing water from accumulating on the conveyor belt and affecting the conveying effect. The baffle 206 effectively restrains the position of the vegetables, ensuring that the vegetables will not fall during high-speed conveying and improving the reliability of the conveying.

[0056] The washing mechanism 3 includes a transmission roller 301, a cross transmission shaft 302, a transmission belt 304, a brush 305, a drive plate 306, a moving frame 309, a slider 310, a reciprocating screw 311, a drive rod 312, a guide rod 313, a bearing 303, and a slip ring 307. The two sets of transmission rollers 301 are connected to the main body 1 through the cross transmission shaft 302, and the transmission rollers 301 and the cross transmission shaft 302 are radially limited and axially sliding connected.

[0057] Multiple sets of brushes 305 are evenly distributed and fixed on the outside of two sets of transmission belts 304. The transmission belts 304 are wrapped around the outside of two sets of transmission rollers 301. Two sets of drive plates 306 are located on the outside of two sets of transmission belts 304. The movable frame 309 is fixed on the top of the two sets of drive plates 306. The slider 310 is fixed at the middle position of the top of the movable frame 309.

[0058] The reciprocating lead screw 311 passes through the slider 310 and is connected to the main body 1 through the drive rod 312. Two sets of guide rods 313 pass through the movable frame 309 and are fixedly connected to the inner wall of the main body 1 on both sides. The guide rods 313 and the movable frame 309 are slidably connected. The cross drive shaft 302 and the main body 1 are rotatably connected through the bearing 303. The drive plate 306 and the cross drive shaft 302 are slidably connected through the slip ring 307. The slip ring 307 and the cross drive shaft 302 are axially sliding and radially rotating connected.

[0059] When the vegetables enter the washing mechanism 3, the transmission mechanism 4 drives the cross transmission shaft 302 to rotate, which in turn causes the transmission roller 301 to rotate. The transmission roller 301 drives the transmission belt 304 to move, so that the brush 305 washes the vegetables. Due to the special transmission method of the transmission mechanism 4, the brush 305 runs in the opposite direction under the action of the transmission belt 304, that is, opposite to the direction of vegetable conveying. This not only enables the reverse washing operation of vegetables, but also reduces the running speed of vegetables on the conveyor belt 201 to a certain extent, increases the contact time between vegetables and brush 305, and improves the washing effect.

[0060] Meanwhile, the drive rod 312 drives the reciprocating screw 311 to rotate under the drive of the transmission mechanism 4. The reciprocating screw 311 causes the slider 310 to move back and forth on it. The slider 310 drives the transmission roller 301, transmission belt 304 and brush 305 to move back and forth along the cross transmission shaft 302 axially through the moving frame 309 and the drive plate 306, so that the brush 305 can reciprocate and wash the vegetables while running in the opposite direction.

[0061] This reciprocating washing action can more thoroughly clean the surface of vegetables and effectively remove tightly attached dirt. The guide rod 313 plays the role of guiding and stabilizing the moving frame 309 in this process, ensuring that the reciprocating motion of the slider 310 and the brush 305 is smooth. The bearing 303 ensures the smooth rotation of the cross drive shaft 302, and the slip ring 307 enables the drive plate 306 to slide axially and rotate radially stably on the cross drive shaft 302, ensuring the normal operation of the entire washing mechanism 3.

[0062] The transmission mechanism 4 includes a connecting gear 401, a steering gear 402, a transmission gear 403, a coaxial gear 404, a drive gear 406, a first synchronous belt 405, and a second synchronous belt 407. The connecting gear 401 is fixed to the outside of one of the sets of rotating shafts 203, and the steering gear 402 is movably connected to one side of the main body 1 and meshes with the connecting gear 401.

[0063] One set of transmission gears 403 and coaxial gears 404 are fixed to the outside of one set of cross transmission shafts 302, and transmission gears 403 are fixed to the outside of both sets of cross transmission shafts 302. The drive gear 406 is fixed to the outside of one set of drive rods 312. The steering gear 402 and coaxial gear 404 are connected by a first synchronous belt 405. The two sets of transmission gears 403 and drive gears 406 are connected by a second synchronous belt 407.

[0064] Specifically, when the external drive motor drives the conveyor roller 202 to rotate, the connecting gear 401 fixed on the rotating shaft 203 rotates accordingly. The connecting gear 401 meshes with the steering gear 402, transmitting power to the steering gear 402. The steering gear 402 drives the coaxial gear 404 to rotate through the first synchronous belt 405. Since the coaxial gear 404 and the transmission gear 403 are coaxially arranged, the transmission gear 403 also begins to rotate.

[0065] The transmission gears 403 on the outer side of the two sets of cross transmission shafts 302 drive the drive gear 406 to rotate through the second synchronous belt 407, which in turn drives the rod 312 to rotate, ultimately realizing the reverse operation and reciprocating motion of the brush 305 of the washing mechanism 3. The transmission mechanism 4 cleverly distributes and converts the power of the conveying mechanism 2 through the cooperation of a series of gears and synchronous belts, realizing multiple motion modes of the washing mechanism 3, ensuring the coordinated work of the entire device, and improving the cleaning efficiency.

[0066] The rinsing mechanism 5 includes a main water spray pipe 508, a branch water spray pipe 509, a nozzle module 510, a return box 501, a water storage chamber 502, a suction pipe 505, a water pump module 506, a water outlet pipe 507, a support plate 503, and a filter plate 504. The main water spray pipe 508 is fixed on one side of the main body 1. Multiple sets of branch water spray pipes 509 extend through the interior of the washing mechanism 3 inside the main body 1, and the multiple sets of branch water spray pipes 509 are connected to the main water spray pipe 508. Each set of branch water spray pipes 509 has multiple sets of nozzle modules 510 installed at one end at an angle.

[0067] The return box 501 is located at one end of the main body 1, and the water storage chamber 502 opened in the return box 501 is connected to the interior of the main body 1. The water pump module 506 is installed at the bottom of one end of the main body 1. The water inlet of the water pump module 506 is connected to the return box 501 through the water suction pipe 505, and the water outlet of the water pump module 506 is connected to the water spray main pipe 508 through the water outlet pipe 507. The support plate 503 is located inside the return box 501 and is slidably connected to it. Multiple sets of inclined filter plates 504 are evenly fixed at one end of the support plate 503. A cover plate is provided on the top of the return box 501, and the cover plate is movably connected to the return box 501.

[0068] Specifically, when the water pump module 506 is working, it draws filtered water from the water storage chamber 502 of the return box 501 through the suction pipe 505, and then transports the water to the main spray pipe 508 through the outlet pipe 507. The water is then distributed to each spray branch pipe 509 in the main spray pipe 508, and finally sprayed out from the nozzle module 510. The nozzle module 510 is tilted so that the pressurized water is sprayed at a certain angle onto the vegetables to wash the mud on the surface of the vegetables. Since the angle of the nozzle module 510 is facing the feed end of the conveying mechanism 2, the water in the main body 1 flows to the return box 501 under the action of the rinsing water flow, and the washed mud enters the return box 501 with the water flow.

[0069] Multiple filter plates 504 in the return box 501 filter sludge to prevent it from re-entering the circulating water system. The filtered water enters the water storage chamber 502, realizing the recycling of water resources and saving water resources. When the filter plates 504 need to be cleaned, the cover plate on the top of the return box 501 is opened, and the support plate 503 and the filter plates 504 are taken out as a whole for cleaning through the groove on the top of the support plate 503, which improves the filtration efficiency and ensures the long-term stable operation of the flushing mechanism 5.

[0070] The bubble generating mechanism 6 includes an air pump module 601, a jet main pipe 602, jet branch pipes 603, and a sealing ring 604. The jet main pipe 602 is connected to the air outlet end of the air pump module 601. Multiple sets of jet branch pipes 603 extending to the bottom of the main body 1 are evenly fixed inside the jet main pipe 602. A sealing ring 604 is provided between each set of jet branch pipes 603 and the main body 1.

[0071] When the air pump module 601 is working, it draws in external air and delivers it to the air branch pipe 603 through the air jet main pipe 602. The air jet branch pipe 603 injects the air into the water at the bottom of the main body 1 to form bubbles. The function of the sealing ring 604 is to prevent gas leakage and ensure that the bubbles can be effectively generated in the water. As the bubbles rise in the water, they cause the vegetables to tumble and rub against each other in the washing tank, further improving the cleaning effect. This helps to remove some hard-to-clean dirt from the surface of vegetables, such as stubborn mud in the folds and root joints. It also helps to remove pesticide residues from the surface of vegetables and improve the preservation effect of pre-cooked vegetables.

[0072] The discharge conveying module 8 is fixedly connected to one end of the main body 1 and is set at an inclination. Its function is to convey the cleaned vegetables out of the main body 1 for subsequent processing or packaging. The discharge conveying module 8 can be driven by a separate drive motor or by connecting it to the conveying roller 202 via a belt to ensure that the vegetables can be smoothly output from the device and complete the cleaning process of the entire pre-prepared vegetable preservation production.

[0073] The working principle of this invention is as follows: When in use, the power supply is turned on, and the external power supply equipment supplies power to the water pump module 506 and the air pump module 601 through the wires, so that the water pump module 506 can ensure the circulation of water flow, and the air pump module 601 can absorb external gas and inject it into the water inside the main body 1 to form bubbles.

[0074] Meanwhile, the output shaft of the external drive motor and the transmission hole 204 are engaged and connected to each other, so that the external drive motor can drive one of the conveyor rollers 202 to rotate. Since the two sets of conveyor rollers 202 are connected to each other through the conveyor belt 201, the external drive motor can drive the conveyor belt 201 to transport vegetables.

[0075] A discharge conveying module 8 is provided at the end of the main body 1. The discharge conveying module 8 can be driven by a separate drive motor or by being connected to the conveying roller 202 by a belt.

[0076] When vegetables such as potatoes and radishes need to be washed, the staff pours the vegetables onto the top of the conveyor 2. The vegetables then enter the washing mechanism 3 under the action of the conveyor belt 201. The multiple brushes 305 of the washing mechanism 3 can perform reciprocating washing action on the vegetables. In conjunction with the multiple nozzle modules 510 of the rinsing mechanism 5, the water flow is pressurized to a certain degree to simultaneously rinse the vegetables. As can be seen from the above, the overall vegetable washing process is good.

[0077] Specifically, the connecting gear 401 and the steering gear 402 mesh with each other, the steering gear 402 and the coaxial gear 404 are connected by the first synchronous belt 405, since the coaxial gear 404 and the transmission gear 403 are coaxially arranged and are both located on the outside of one set of cross transmission shafts 302, and the transmission gear 403 and the drive gear 406 arranged on one side of the two sets of cross transmission shafts 302 are connected by the second synchronous belt 407;

[0078] As can be seen above, when the conveyor belt 201 is conveying vegetables in the forward direction, the multiple sets of brushes 305 of the washing mechanism 3 are running in the reverse direction under the action of the transmission belt 304. That is to say, the brushes 305 running in the reverse direction can not only perform reverse washing operation on the vegetables, but also reduce the running speed of the vegetables on the conveyor belt 201 to a certain extent, thereby improving the washing effect of the vegetables.

[0079] Furthermore, since the drive gear 406 and the transmission gear 403 are connected by the second synchronous belt 407, the drive gear 406 synchronously drives one of the drive rods 312 to rotate, the drive rod 312 drives the reciprocating screw 311 to rotate, and then the slider 310 is driven to reciprocate under the action of the reciprocating screw 311.

[0080] In other words, the reciprocating movement of the slider 310 at this time drives the two sets of transmission rollers 301, transmission belts 304 and multiple sets of brushes 305 to move axially along the two sets of cross transmission shafts 302 through the two sets of moving frames 309 and two sets of drive plates 306. This allows the multiple sets of brushes 305 to perform reciprocating washing action on the vegetables while running in the opposite direction, further improving the cleaning effect of the vegetables.

[0081] During the vegetable washing process, the bubble generating mechanism 6 injects gas into the water inside the main body 1 through the air pump module 601, the jet main pipe 602, and the jet branch pipe 603 to form bubbles. The bubbles cause the vegetables to roll and rub against each other in the washing tank, which further improves the washing effect of the vegetables and ensures the freshness of the subsequent pre-cooked vegetables.

[0082] At the same time, the multiple sets of nozzle modules 510 of the rinsing mechanism 5 simultaneously rinsing the vegetables, so that the mud on the surface of the vegetables can be effectively removed. In detail, since the angle of the multiple sets of nozzle modules 510 is facing the feeding end of the conveying mechanism 2, the water inside the main body 1 gradually flows to the return box 501 at one end of the main body 1 under the action of the rinsing water flow of the nozzle modules 510. Since the water contains continuously generated bubbles, the mud washed off can flow into the return box 501 with the flow of water.

[0083] At this time, the multiple sets of filter plates 504 inside the return box 501 can filter the sludge. The filtered water enters the water storage chamber 502. Under the suction of the water pump module 506, the filtered water in the water storage chamber 502 is drawn through the water suction pipe 505, through the water outlet pipe 507, the main spray pipe 508, and into the multiple sets of spray branch pipes 509. Then, it can be sprayed again through the multiple sets of nozzle modules 510 onto the surface of the vegetables on the conveyor belt 201 for circulating rinsing.

[0084] Since the multi-nozzle module 510 is located inside the multi-brush 305, when the multi-brush 305 runs in the reverse direction with the transmission belt 304, the multi-nozzle module 510 can spray a portion of the water onto the brush 305, thereby quickly washing away the mud trapped inside the brush 305 and improving the washing process of the brush 305 on vegetables.

[0085] Furthermore, since the diameter of the connecting gear 401 is larger than that of the steering gear 402 and the coaxial gear 404, the forward running speed of the conveyor belt 201 is lower than the reverse running speed of the multiple sets of brushes 305. As a result, during the slow forward running of the vegetables, the multiple sets of brushes 305 increase the washing frequency of the vegetables, further improving the cleaning effect of the vegetables.

[0086] Similarly, since the diameter of the transmission gear 403 is larger than that of the drive gear 406, the reciprocating brushing frequency of the multiple sets of brushes 305 is increased, and the rapid brushing action can effectively remove the mud adhering to the surface of the vegetables.

[0087] As can be seen from the above, the present invention enables the water pump module 506 to ensure water circulation and the air pump module 601 to inject gas to form bubbles through external power supply, which, together with the external drive motor, drives the conveyor belt 201 to transport vegetables, ensuring stable operation of the equipment.

[0088] Secondly, by utilizing the reverse and reciprocating motion of the brush 305 of the washing mechanism 3 and working in conjunction with the nozzle module 510 of the rinsing mechanism 5, the dirt on the surface of vegetables can be effectively removed. At the same time, the air bubbles can make the vegetables roll and rub in the washing tank, further improving the cleaning effect.

[0089] Fourth, a return box 501 and related water circulation components are installed to achieve water filtration and recycling, thus saving water resources.

[0090] Fifth, by utilizing the reasonable size differences between the various components, the brush can increase the frequency and action of washing vegetables, thus more thoroughly removing the mud adhering to the surface of the vegetables. Overall, this greatly improves the cleaning effect of vegetables and ensures the freshness of the prepared dishes.

8. A method of using a pre-prepared food preservation production device, characterized in that... The process of using the pre-prepared food preservation production apparatus according to any one of claims 1-7 to perform preservation production includes the following steps: S1: Vegetable conveying: Start the external drive motor to drive the conveyor roller (202) to rotate, and then the conveyor belt (201) will convey the vegetables. The vegetables enter the equipment from the top end of the conveyor mechanism (2). The discharge conveying module (8) can be driven by a separate drive motor or by connecting the conveyor roller (202) with a belt. The main body (1) is ready to receive the cleaned vegetables at the end. S2: Cleaning process: Brush washing and rinsing in tandem: When vegetables enter the washing mechanism (3), the multiple sets of brushes (305) of the washing mechanism (3) run in reverse under the action of the transmission belt (304) to wash the vegetables in reverse and reduce their running speed on the conveyor belt (201), increase the cleaning time and improve the cleaning effect. At the same time, the multiple sets of nozzle modules (510) of the rinsing mechanism (5) spray pressurized water onto the vegetables to rinse the mud on their surface. Enhanced washing effect of reciprocating brush: Through the transmission mechanism (4), the drive rod (312) drives the reciprocating screw (311) to rotate, which in turn drives the slider (310) to move back and forth.

Bubble-assisted cleaning: The bubble generating mechanism (6) injects gas into the water inside the main body (1) through the air pump module (601), the jet main pipe (602), and the jet branch pipe (603) to form bubbles, causing the vegetables to roll and rub against each other in the cleaning tank, further improving the cleaning effect; S3: Water circulation and sludge treatment: Sludge flows to the return box with water: Since the nozzle module (510) is angled toward the feed end of the conveying mechanism (2), the water in the main body (1) flows to the return box (501) under the action of the flushing water flow, and the sludge washed off enters the return box (501) with the water flow. Filtration and Recycling: Multiple filter plates (504) in the return box (501) filter the sludge. The filtered water enters the water storage chamber (502). Under the suction of the water pump module (506), it enters the water spray branch pipe (509) through the water suction pipe (505), water outlet pipe (507), and water spray main pipe (508). Then, it is sprayed onto the surface of the vegetables through the nozzle module (510) to achieve circulating rinsing. At the same time, during the reverse operation of the brush (305), the nozzle module (510) can spray some water onto the brush (305) to rinse the sludge trapped inside. S4: Cleaning complete: The cleaned vegetables are sent out by the discharge conveyor module (8) to complete the entire cleaning process.
