Description

Technical Field

[0001] The present application relates to the technical field related to cleaning of food processing raw materials, and specifically to a food raw material cleaning device for food processing. Background Art

[0002] In the food processing industry, raw material cleaning is one of the key steps to ensure product quality and safety. The cleaning process is particularly important for fruits, especially apples, which are widely consumed food ingredients. Currently, there are two main ways to clean fruits: manual cleaning and mechanical cleaning.

[0003] Manual washing: Although manual washing can ensure the cleanliness of fruits to a certain extent, it is inefficient and requires a lot of manpower. It is not only time-consuming and labor-intensive, but also difficult to meet the needs of efficient production in a large-scale production environment. In addition, manual washing may also cause uneven washing due to human factors, affecting the quality of the final product.

[0004] Mechanical cleaning: Compared with manual cleaning, mechanical cleaning improves cleaning efficiency and reduces labor costs to a certain extent. However, the existing mechanical cleaning method generally uses the method of floating the fruit on the water surface and removing surface dirt by water pressure washing. This cleaning method has obvious shortcomings: since the fruit is in a free state in the water, it is difficult to effectively control its position and posture, resulting in incomplete cleaning, especially the dirt in the depressions on the surface of the fruit is difficult to be effectively removed. In addition, water pressure washing is not effective in removing dirt or pesticide residues tightly adsorbed on the surface of the fruit, affecting the cleaning quality and food safety.

[0005] Therefore, the present application provides a food material cleaning device for food processing to solve the above problems. Summary of the invention

[0006] The present application provides a food raw material cleaning device for food processing, aiming to solve the problems of low efficiency, high labor, time-consuming and labor-intensive manual cleaning, incomplete mechanical flushing and easy to cause dirt residue during the cleaning process of existing food raw materials proposed in the background technology.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a food raw material cleaning device for food processing, comprising a cleaning tank and a bracket arranged at the lower end of the cleaning tank; The interior of the cleaning tank is provided with an intermittent brushing structure for fixedly brushing the fruit, and the intermittent brushing structure includes a toothed belt drive, a plurality of brush rollers arranged side by side on the toothed belt drive, a brush plate arranged above the brush roller, and a driving mechanism for driving the brush plate to move closer to or away from the brush roller; the driving mechanism includes a first crank rotatably mounted on the shaft of the toothed belt drive, a second crank rotatably arranged on the brush plate, and a connecting rod plugged into the second crank and rotatably connected to the first crank. When washing the fruit, first, inject an appropriate amount of clean water into the cleaning tank until the water surface overflows the brush roller. Subsequently, place the fruit to be washed at the feeding end of the cleaning tank. Driven by the toothed belt drive, the brush roller begins to rotate clockwise, which not only drives the flow of water in the cleaning tank, but also prompts the fruit to move between the brush roller and the brush plate along the direction of the water flow. When the fruit enters the area between the brush roller and the brush plate, the shaft of the toothed belt drive simultaneously drives the first crank to rotate clockwise. The first crank is connected to the second crank through a connecting rod, so as the first crank rotates, the second crank also rotates, thereby driving the brush plate to move downward. The downward movement of the brush plate presses the fruit tightly between the adjacent brush rollers and the brush plate. At this time, the rotating brush rollers and the brush plate work together to brush the fruit firmly and powerfully. The intermittent brushing method not only avoids the damage to the fruit that may be caused by continuous brushing, but also ensures that every corner of the fruit can be fully cleaned by changing the brushing position.

[0008] Preferably, in order to facilitate the brush plate to adapt to fruits of different sizes: a guide groove for the connecting rod to move up and down is provided at the bottom of the second crank, a guide rod fixedly connected to the guide groove is slidably inserted on the connecting rod, and a spring is provided on the guide rod corresponding to the guide groove and the connecting rod. By introducing a spring elastic force adjustment mechanism, the adaptability and flexibility of the brush plate are further enhanced. This mechanism allows the brush plate to automatically adjust its holding force and position according to the size of the fruit, thereby ensuring that the fruit can be stably and effectively brushed regardless of its size.

[0009] Preferably, in order to speed up the entry of fruits from the feeding end of the cleaning tank into the space between the brush roller and the brush plate: the feeding end of the cleaning tank is provided with a feeding hopper, the end of the feeding hopper corresponds to the space between the brush roller and the brush plate, and the bottom wall in the feeding hopper is inclined. The introduction of the feeding hopper not only speeds up the entry of fruits from the feeding end of the cleaning tank into the space between the brush roller and the brush plate, but also ensures the stability and orderliness of the fruits during the transportation process.

[0010] Preferably, in order to facilitate the gathering of fruits to the middle of the brush roller: the upper hopper is in a trapezoidal shape, that is, the feeding port of the upper hopper is larger than its discharging port. The design of the trapezoidal upper hopper enables the fruits to naturally gather to the middle of the brush roller during the conveying process, thereby ensuring the uniform distribution of the fruits in the brushing area.

[0011] Preferably, in order to facilitate the removal of washed fruits: a conveyor belt is provided at the discharge end of the washing tank, and the conveyor belt is installed on the toothed belt drive. By cleverly integrating the conveyor belt into the toothed belt drive, the washed fruits can be removed efficiently and conveniently. This design not only reduces the use of additional drive components, reduces equipment costs and energy consumption, but also improves the compactness and integration of the overall device.

[0012] Preferably, in order to facilitate the discharge of the fruits discharged from the conveyor belt: a guide plate is fixedly provided at one end of the conveyor belt away from the brush roller. The guide plate can not only guide the fruits discharged from the conveyor belt but also support the conveyor belt to ensure the stability of the conveyor belt.

[0013] Preferably, in order to conveniently discharge the sewage in the cleaning tank: a sewage pipe connected to the interior of the cleaning tank is fixedly provided on the cleaning tank, and a sewage valve is fixedly installed on the sewage pipe. The sewage in the cleaning tank can be conveniently discharged through the sewage pipe, and the sewage valve can control the opening and closing of the sewage pipe.

[0014] Preferably, in order to prevent the dirt deposited in the cleaning tank from rolling upward: a grille is provided inside the cleaning tank, and the grille is located below the intermittent scrubbing structure. During the cleaning process, the dirt washed off enters the bottom of the cleaning tank through the holes on the grille, and then the grille can reduce the impact of the water flow on the bottom of the cleaning tank, thereby reducing the occurrence of dirt rolling.

[0015] Preferably, in order to facilitate rinsing the surface of the fruit during intermittent brushing of the fruit: the washing tank is provided with a flushing structure for flushing the fruit, the flushing structure comprises a water tank, a flushing pipe fixedly mounted on the brush plate, a rotating nozzle plugged on the brush plate and fixedly connected to the flushing pipe, and a water pump fixedly mounted on the water tank and connected to the inside of the water tank, the output end of the water pump being fixedly connected to the flushing pipe via a corrugated hose. The flushing structure can provide additional water flow flushing during the intermittent brushing of the fruit, effectively removing dirt and impurities on the surface of the fruit, further enhancing the thoroughness and uniformity of the cleaning.

[0016] The food raw material cleaning device used for food processing can ensure that the fruit is evenly and vigorously scrubbed during the cleaning process through an intermittent scrubbing structure, and effectively removes dirt and residues on the surface of the fruit. In addition, the intermittent scrubbing method not only avoids the damage to the fruit that may be caused by continuous scrubbing, but also ensures that every corner of the fruit can be fully cleaned by changing the scrubbing position. At the same time, the water flow driven by the cooperation of the toothed belt drive and the brush roller promotes the circulation of water in the cleaning tank, further enhancing the cleaning effect. In general, the device improves the cleanliness of food raw materials, ensures food safety, and also improves the production efficiency of food processing.

[0017] The present application can provide additional water flow during the intermittent brushing of fruits through the flushing structure, effectively removing dirt and impurities on the surface of the fruits, further enhancing the thoroughness and uniformity of the washing. At the same time, the design of the flushing structure also makes full use of the synergy of the water pump and the rotating nozzle, ensuring the stable supply and uniform distribution of water flow, and improving the stability and reliability of the washing operation.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0021] This embodiment provides a food material cleaning device for food processing, such as Figure 1-6As shown, the cleaning device comprises a cleaning tank 1 and a bracket 11 arranged at the lower end of the cleaning tank 1; an intermittent scrubbing structure 2 for fixed scrubbing of fruits is arranged inside the cleaning tank 1, and the intermittent scrubbing structure 2 comprises a toothed belt driving member 21, a plurality of brush rollers 22 arranged side by side on the toothed belt driving member 21, a brush plate 23 arranged above the brush roller 22, and a driving mechanism 24 for driving the brush plate 23 to move closer to or away from the brush roller 22; the driving mechanism 24 comprises a first crank 241 rotatably mounted on the shaft of the toothed belt driving member 21, a second crank 242 rotatably arranged on the brush plate 23, and a connecting rod 243 plugged into the second crank 242 and rotatably connected to the first crank 241. The food raw material cleaning device for food processing improves the cleaning efficiency and quality of fruits through the designed intermittent scrubbing structure 2. Specifically, the structure can ensure that the fruits are evenly and forcefully scrubbed during the cleaning process, and effectively remove the dirt and residues on the surface of the fruits. In addition, the intermittent scrubbing method not only avoids the damage that may be caused to the fruit by continuous scrubbing, but also ensures that every corner of the fruit can be fully cleaned by changing the scrubbing position. At the same time, the water flow driven by the cooperation of the toothed belt drive 21 and the brush roller 22 promotes the circulation of water in the cleaning tank 1, further enhancing the cleaning effect. In general, the device improves the cleanliness of food raw materials, ensures food safety, and also improves the production efficiency of food processing. When cleaning the fruit, first, inject an appropriate amount of clean water into the cleaning tank 1 until the water surface overflows the brush roller 22. Then, place the fruit to be cleaned at the feeding end of the cleaning tank 1. Driven by the toothed belt drive 21, the brush roller 22 begins to rotate clockwise, which not only drives the flow of water in the cleaning tank 1, but also prompts the fruit to move between the brush roller 22 and the brush plate 23 along the direction of the water flow. When the fruit enters the area between the brush roller 22 and the brush plate 23, the shaft of the toothed belt drive 21 simultaneously drives the first crank 241 to rotate clockwise. The first crank 241 is connected to the second crank 242 through a connecting rod 243, so as the first crank 241 rotates, the second crank 242 also rotates, thereby driving the brush plate 23 to move downward. The downward movement of the brush plate 23 presses the fruit tightly between the adjacent brush rollers 22 and the brush plate 23. At this time, the rotating brush rollers 22 and the brush plate 23 work together to brush the fruit firmly and effectively. The intermittent brushing method not only avoids the damage to the fruit that may be caused by continuous brushing, but also ensures that every corner of the fruit can be fully cleaned by changing the brushing position.

[0022] In order to facilitate the brush plate 23 to adapt to fruits of different sizes: a guide groove 2421 for the connecting rod 243 to move up and down is provided at the bottom of the second crank 242, a guide rod 2422 fixedly connected to the guide groove 2421 is slidably inserted on the connecting rod 243, and a spring 2423 is arranged between the corresponding guide groove 2421 and the connecting rod 243 on the guide rod 2422. By introducing the spring 2423 elastic force adjustment mechanism, the adaptability and flexibility of the brush plate 23 are further enhanced. Specifically, the mechanism allows the brush plate 23 to automatically adjust its holding force and position according to the size of the fruit, thereby ensuring that the fruit can be stably and effectively brushed regardless of its size. In addition, the introduction of the spring 2423 also increases the durability and reliability of the device, so that it can adapt to a wider range of food processing needs. In terms of the working principle of the brush plate 23 adapting to fruits of different sizes, the device utilizes the elastic force adjustment function of the spring 2423. When fruits of different sizes are placed between the brush roller 22 and the brush plate 23, the brush plate 23 will be pushed upward by the fruit. At this time, the connecting rod 243 slides in the guide groove 2421, and the guide rod 2422 slides on the connecting rod 243 and compresses the spring 2423. The elastic force of the spring 2423 enables the brush plate 23 to automatically adjust its position according to the size of the fruit, ensuring that the brush plate 23 always fits tightly and stably presses the fruit. Specifically, when the fruit is large, the brush plate 23 will be subjected to a large upward thrust, causing the spring 2423 to be compressed. The compression of the spring 2423 will resist the upward movement trend of the brush plate 23, thereby maintaining the stable pressure of the brush plate 23 on the fruit. In addition, the introduction of the spring 2423 also increases the buffering performance of the brush plate 23, reducing the potential damage to the fruit caused by hard contact. At the same time, the design of the guide groove 2421 and the guide rod 2422 ensures the stability and accuracy of the connecting rod 243 during the sliding process, thereby improving the reliability and durability of the entire scrubbing structure.

[0023] Furthermore, in order to speed up the entry of fruits from the feeding end of the cleaning tank 1 into the space between the brush roller 22 and the brush plate 23: the feeding end of the cleaning tank 1 is provided with an upper hopper 3, the end of the upper hopper 3 corresponds to the space between the brush roller 22 and the brush plate 23, and the bottom wall in the upper hopper 3 is inclined. The introduction of the upper hopper 3 not only speeds up the entry of fruits from the feeding end of the cleaning tank 1 into the space between the brush roller 22 and the brush plate 23, but also ensures the stability and orderliness of the fruits during the transportation process. This design reduces the cumbersomeness of manual operation, reduces labor intensity, and improves the automation of the cleaning process. In addition, the inclined bottom wall design of the upper hopper 3 helps the fruits to slide smoothly under the action of gravity, avoids the accumulation and jamming of fruits during the transportation process, and further improves the cleaning efficiency and quality. When the operator pours the fruits to be cleaned into the upper hopper 3, the fruits will slide down along the inclined bottom wall under the action of gravity. As the fruits slide down, they will gradually approach the brushing area between the brush roller 22 and the brush plate 23. Since the end of the upper hopper 3 corresponds to the brushing area, the fruit can smoothly enter the area and be brushed by the brush roller 22 and the brush plate 23. The inclined bottom wall helps the fruit to slide down at a certain speed and direction, avoiding accumulation and jamming caused by uneven speed or direction change.

[0024] Furthermore, in order to facilitate the gathering of fruits to the middle of the brush roller 22: the upper hopper 3 is in a trapezoidal shape, that is, the feeding port of the upper hopper 3 is larger than its discharge port. The design of the trapezoidal upper hopper 3 allows the fruits to naturally gather to the middle of the brush roller 22 during transportation, thereby ensuring the uniform distribution of the fruits in the brushing area. When the operator pours the fruits to be washed into the trapezoidal upper hopper 3, the fruits will slide down along the bucket wall under the action of gravity. Since the feeding port is larger than the discharge port, the fruits will gradually be squeezed and guided by the bucket wall during the sliding process, so that they will gather in the direction of the discharge port. As the fruits gather, they will gradually enter the brushing area between the brush roller 22 and the brush plate 23, and be brushed by the brush roller 22. In addition, the design of the trapezoidal upper hopper 3 also takes into account the stability and smoothness of the fruits during transportation. The inclination angle and smoothness of the bucket wall are optimized to ensure that the fruits will not get stuck or pile up during the sliding process.

[0025] In order to facilitate the removal of washed fruits: a conveyor belt 4 is provided at the discharge end of the washing tank 1, and the conveyor belt 4 is mounted on the toothed belt drive 21. By cleverly integrating the conveyor belt 4 into the toothed belt drive 21, the washed fruits can be removed efficiently and conveniently. This design not only reduces the use of additional drivers, reduces equipment costs and energy consumption, but also improves the compactness and integration of the overall device. At the same time, the introduction of the conveyor belt 4 enables the fruits to be automatically and orderly output after washing, greatly reducing the labor intensity of the operator and improving production efficiency. In addition, the coordinated work of the conveyor belt 4 and the toothed belt drive 21 ensures the stability and continuity of the fruits during the transportation process, further improving the overall effect of washing and output. In terms of the working principle of removing washed fruits, the device makes full use of the driving capacity of the toothed belt drive 21 and the conveying function of the conveyor belt 4. The conveyor belt 4 is mounted on the toothed belt drive 21 and shares the same power source with the drive system of the brush roller 22. When the toothed belt drive 21 is working, it simultaneously drives the rotation of the brush roller 22 and the rotation of the conveyor belt 4. After the fruits are brushed by the brush roller 22 and the brush plate 23 in the cleaning tank 1, they are conveyed to the discharge end of the cleaning tank 1. At this time, the conveyor belt 4 is already in working state, and as the conveyor belt 4 rotates, it will take the washed fruits out of the cleaning tank 1 and move forward along the predetermined conveying path.

[0026] In order to facilitate the discharge of the fruits transported from the conveyor belt 4, a guide plate 41 is fixedly provided at one end of the conveyor belt 4 away from the brush roller 22. The guide plate 41 can not only guide the fruits discharged from the conveyor belt 4 but also support the conveyor belt 4 to ensure the stability of the conveyor belt 4.

[0027] In order to conveniently discharge the sewage in the cleaning tank 1: a sewage pipe 5 connected to the inside of the cleaning tank 1 is fixedly provided on the cleaning tank 1, and a sewage valve 51 is fixedly installed on the sewage pipe 5. The sewage in the cleaning tank 1 can be conveniently discharged through the sewage pipe 5, and the opening and closing of the sewage pipe 5 can be controlled by the sewage valve 51.

[0028] In order to prevent the dirt deposited in the cleaning tank 1 from rolling upward: a grille 6 is provided inside the cleaning tank 1, and the grille 6 is located below the intermittent scrubbing structure 2. During the cleaning process, the dirt washed away enters the bottom of the cleaning tank 1 through the holes on the grille 6, and then the grille 6 can reduce the impact of the water flow on the bottom of the cleaning tank 1, thereby reducing the rolling of the dirt.

[0029] In order to facilitate the washing of the surface of the fruit during the intermittent brushing of the fruit: the washing tank 1 is provided with a washing structure 7 for washing the fruit, the washing structure 7 comprises a water tank 71, a washing pipe 72 fixedly mounted on the brush plate 23, a rotating nozzle 73 plugged on the brush plate 23 and fixedly connected to the washing pipe 72, and a water pump 74 fixedly mounted on the water tank 71 and connected to the inside of the water tank 71, and the output end of the water pump 74 is fixedly connected to the washing pipe 72 through a corrugated hose 75. The washing structure 7 can provide additional water flow for washing during the intermittent brushing of the fruit, effectively removing dirt and impurities on the surface of the fruit, further enhancing the thoroughness and uniformity of the washing. At the same time, the design of the washing structure 7 also makes full use of the synergistic effect of the water pump 74 and the rotating nozzle 73, ensuring the stable supply and uniform distribution of water flow, and improving the stability and reliability of the washing operation. During the cleaning process, when the intermittent scrubbing structure 2 scrubs the fruit, the water pump 74 starts to extract the water flow in the water tank 71, and then transports it to the flushing pipe 72 through the corrugated hose 75. As the water flows in, the pressure in the flushing pipe 72 gradually increases, thereby driving the rotating spray head 73 to start working. The rotating spray head 73 rotates under the action of pressure, and sprays the water flow evenly on the surface of the fruit.

[0030] The wiring diagram of the toothed belt drive 21 in the present invention is common knowledge in the art, and its working principle is a known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the toothed belt drive 21 will not be explained in detail.

[0031] It should be noted that the various standard parts used in the present invention are all available on the market, and non-standard parts can be specially customized. The connection methods adopted in the present invention, such as bolt connection, welding, etc., are also very common means in the mechanical field, and the inventor will not go into details here.
