Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable processing equipment technology, specifically to an integrated device for washing and drying fruits and vegetables. Background Technology

[0002] In the production, processing, distribution, and pre-processing of fresh fruits and vegetables, washing and drying are indispensable pre-processing steps that directly determine the cleanliness, shelf life, appearance, and food safety of fruits and vegetables.

[0003] Patent publication number CN217564874U includes a frame, a cleaning assembly, and a drying assembly. The frame includes a high-level support and a low-level support, which are cross-stacked and connected. The cleaning assembly includes a first drive motor, a booster pump, a first circulating support chain, a transport water pipe, a cleaning water pipe, a cleaning nozzle, and a water tank. The first drive motor and the first circulating support chain are located within the high-level support. The first drive motor drives the first circulating support chain to circulate along the connection direction of the first crossbar and the connecting diagonal bar. The water tank is connected to the transport water pipe and is pressurized and transported to the cleaning water pipe and the cleaning nozzle by the booster pump. The drying assembly includes a second drive motor, a second circulating support chain, and a rotating blower. The second drive motor drives the second circulating support chain to rotate and drives the rotating blower to rotate around the support shaft. It has the advantages of good cleaning effect and simultaneous drying.

[0004] The aforementioned patent describes a device that uses a hair dryer to dry fruits and vegetables, allowing for drying from different angles and distances. However, when cleaning fruits and vegetables, the device's cleaning nozzle is difficult to adjust, which can cause it to miss impurities hidden between the fruits and vegetables, making it difficult to effectively clean them. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an integrated device for washing and drying fruits and vegetables, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an integrated vegetable and fruit washing and drying device, comprising a conveyor table with a pressure roller mounted on the conveyor table, a baffle mounted on the conveyor table, and a fixing plate mounted on the conveyor table; the integrated vegetable and fruit washing and drying device further comprises a swing mechanism and a drying mechanism mounted on the conveyor table. The swing mechanism includes a rotating rod mounted on the fixed plate, a conveying pipe mounted on the rotating rod, and a water spray pipe mounted on the conveying pipe. The swing mechanism is used to adjust the rinsing direction of the water flow to improve the cleaning effect on fruits and vegetables. When cleaning fruits and vegetables, the conveying pipe sprays water through an external water source, which directly acts on the surface of the fruits and vegetables. The kinetic energy of the water flow is used to quickly wash away impurities such as mud, dust, insect eggs, and insect excrement attached to the surface of the fruits and vegetables. The sprayed water can quickly reduce the surface temperature of the fruits and vegetables. The drying mechanism includes a U-shaped plate installed on the conveyor table and a cylinder installed on the U-shaped plate. The drying mechanism is used to remove moisture from the surface of vegetables. After the fruits and vegetables are cleaned, it can increase the sweeping area of ​​hot air and continuously change the air outlet angle and coverage area. This ensures that hot air can be evenly applied to each surface evenly, whether the fruits and vegetables are laid flat, stacked, or turned over, thus greatly improving the drying uniformity and avoiding the problems of localized undried or over-dried areas.

[0007] The drying mechanism further includes a fixed rod mounted on the cylinder, a rotating rod II mounted on the fixed rod, a connecting plate I mounted on the rotating rod II, a hinge plate mounted on the rotating rod II, a chamfer plate mounted on the conveyor table, a rotating rod III mounted on the chamfer plate, a hot air blower mounted on the rotating rod III, and a connecting plate II mounted on the rotating rod III. The hot air blower is used to blow hot air onto the surface of fruits and vegetables. During operation, the rotating rod III will drive the hot air blower to rotate to improve the drying effect. The hot air blower has at least one front hot air blower that is relatively spaced apart from the front.

[0008] The second connecting plate is connected to the hinge plate, and the conveying pipe is connected to the first connecting plate. During the washing of fruits and vegetables, surface moisture is replenished to maintain their freshness and delay wilting, yellowing, and softening due to water loss. During the rinsing process, the direction of the water jet can be changed, allowing the water to wash the fruits and vegetables from different directions. This enables flexible adjustment of the water jet direction and coverage area based on the conveying posture and accumulation thickness of the fruits and vegetables, ensuring precise water coverage of all surfaces. This achieves three-dimensional, multi-angle rinsing, removing surface dust and penetrating crevices and hard-to-reach areas, thereby improving the overall thoroughness and uniformity of cleaning and preventing incomplete cleaning in certain areas.

[0009] The drying mechanism also includes a cleaning mechanism installed on the conveyor table, the cleaning mechanism including a rotating shaft installed on the conveyor table, a transmission wheel installed on the rotating shaft, and a brush plate installed on the rotating shaft; The transmission wheel is in contact with the conveyor table. During operation, the conveyor table drives the transmission wheel to rotate. The brush plate is used to clean the surface of fruits and vegetables. During the conveying process, the brush plate rotates and comes into contact with the surface of fruits and vegetables, thereby directly peeling off and cleaning the stubborn impurities on the surface of fruits and vegetables, solving the problem of stubborn dirt that cannot be handled by spray cleaning, and significantly improving the thoroughness of cleaning. At the same time, for hard-to-clean areas such as dents and around the stems of fruits and vegetables, the brush can make deep contact, improving the overall cleaning effect.

[0010] The cleaning mechanism also includes an L-shaped plate installed on the conveyor platform, a sliding rod installed on the L-shaped plate, an inclined plate installed on the sliding rod, and a semi-circular block installed on the baffle. A spring is provided between the inclined plate and the L-shaped plate.

[0011] The conveyor table is in contact with the inclined plate. The spring is used to push the inclined plate to reset. The inclined plate is used to shake off the water droplets on the surface of the fruits and vegetables. During the cleaning process of the fruits and vegetables, an impact force is generated on the conveyor table, causing it to shake. After the conveyor table shakes, the water droplets on the surface of the fruits and vegetables are further shaken off. This can be combined with the hot air blower to dehydrate the fruits and vegetables simultaneously, which can significantly reduce the moisture content on the surface of the fruits and vegetables, reduce the drying pressure of the hot air blower, shorten the drying time, and improve the drying effect of the fruits and vegetables.

[0012] The cleaning mechanism also includes a turning mechanism installed on the conveyor table. The turning mechanism includes a flip plate installed on the inclined plate, a rounded corner plate installed on the conveyor table, a sieve frame installed on the rounded corner plate, and a raised strip installed on the sieve frame. The flip plate is used to turn the fruits and vegetables. During the drying process, it can prevent the leaves from stacking together, causing the hot air to blow only on one side of the vegetables, resulting in uneven drying. In addition, it can eliminate drying blind spots, so that the fruits and vegetables are heated and aired evenly on both sides, improving drying uniformity and efficiency, reducing energy consumption, avoiding local overheating damage to fruits and vegetables, ensuring the appearance and nutritional quality of fruits and vegetables, and at the same time, it can loosen the stacked materials, reduce fruit and vegetable damage, facilitate subsequent discharge and packaging, reduce the risk of spoilage caused by uneven moisture content, and extend the shelf life of fruits and vegetables.

[0013] The flipping mechanism also includes a slant rod installed on the conveyor table, a perforated plate installed on the slant rod, an elastic rod installed on the perforated plate, and a push plate installed on the elastic rod. A spring is provided between the push plate and the perforated plate, and the push plate is used to reset the screen frame.

[0014] The push plate is in contact with the sieve frame, and the flip plate is in contact with the conveyor. After drying, the sieve frame can swing and sieve fruits of different sizes through the holes on the surface of the sieve frame during the shaking. This enables the fruits to be graded by size, avoids uneven processing, improves the overall processing quality of the fruits, and eliminates the need for manual sorting, thus reducing labor costs.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, during the washing of fruits and vegetables, the conveying pipe sprays water from an external water source, directly acting on the surface of the fruits and vegetables. Utilizing the kinetic energy of the water flow, it quickly washes away impurities such as mud, dust, insect eggs, and insect droppings adhering to the surface. The sprayed water can rapidly lower the surface temperature of the fruits and vegetables while replenishing surface moisture, maintaining their freshness and delaying wilting, yellowing, and softening due to water loss. During the rinsing process, the direction of the water jet can be changed, allowing the water to flow from different directions onto the fruits and vegetables, thus adapting to the conveying posture and thickness of the accumulated fruit and vegetables. The system allows for flexible adjustment of the water jet direction and coverage area, ensuring precise water coverage of all surfaces of fruits and vegetables. This achieves three-dimensional, multi-angle rinsing, removing surface dust and penetrating deep into crevices and corners, thus improving the overall thoroughness and uniformity of cleaning and preventing incomplete cleaning in certain areas. After cleaning, the system increases the area swept by the hot air, continuously changing the air outlet angle and coverage area. Whether the fruits and vegetables are laid flat, stacked, or turned over, the hot air is evenly applied to all surfaces, significantly improving drying uniformity and avoiding problems of localized sparse or overly dry areas.

[0016] 2. In this invention, during the conveying process, the rotating brush plate comes into contact with the surface of fruits and vegetables, thereby directly peeling off and cleaning stubborn impurities from the surface of the fruits and vegetables. This solves the problem of stubborn dirt that cannot be handled by spray cleaning methods, significantly improving the thoroughness of cleaning. At the same time, for hard-to-clean areas such as crevices and around the stems of fruits and vegetables, the brush can make deep contact, improving the overall cleaning effect. During the cleaning of fruits and vegetables, the impact force on the conveyor table causes the conveyor table to shake. After the conveyor table shakes, the water droplets on the surface of the fruits and vegetables are further shaken off, which can be used in conjunction with the hot air blower to dehydrate the fruits and vegetables at the same time. This can greatly reduce the moisture content on the surface of the fruits and vegetables, reduce the drying pressure of the hot air blower, shorten the drying time, and improve the drying effect of the fruits and vegetables.

[0017] 3. In this invention, during the fruit and vegetable drying process, the leaves are prevented from piling up, which would cause uneven drying due to hot air blowing only on one side of the vegetables. This eliminates drying blind spots, ensuring that both sides of the fruits and vegetables are heated and aired evenly, improving drying uniformity and efficiency, reducing energy consumption, avoiding localized overheating damage to fruits and vegetables, and ensuring their appearance and nutritional quality. It also loosens and separates piled materials, reducing fruit and vegetable breakage, facilitating subsequent unloading and packaging, reducing the risk of spoilage due to uneven moisture content, and extending the shelf life of fruits and vegetables. After drying, the sieve frame can swing, and during the shaking, fruits of different sizes are sieved through the holes on the sieve frame surface, thus enabling fruit grading by size, avoiding uneven processing, improving the overall quality of fruit processing, and eliminating the need for manual sorting, reducing labor costs.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please see Figures 1-3 One embodiment of the present invention is: an integrated vegetable and fruit washing and drying device, including a conveyor 1, a pressure roller 2 installed on the conveyor 1, a baffle 3 installed on the conveyor 1, and a fixing plate 4 installed on the conveyor 1. The integrated vegetable and fruit washing and drying device also includes a swing mechanism and a drying mechanism installed on the conveyor 1. The oscillating mechanism includes a rotating rod 5 mounted on the fixed plate 4, a conveying pipe 6 mounted on the rotating rod 5, and a water spray pipe 7 mounted on the conveying pipe 6. The oscillating mechanism is used to adjust the rinsing direction of the water flow to improve the cleaning effect on fruits and vegetables. It acts directly on the surface of fruits and vegetables, using the kinetic energy of the water flow to quickly wash away impurities such as mud, dust, insect eggs, and insect excrement attached to the surface of fruits and vegetables. It can also change the spray direction of the water flow, so that it can rinse the fruits and vegetables from different directions, flexibly adjusting the spray direction and coverage area. The drying mechanism includes a U-shaped plate 8 mounted on the conveyor table 1 and a cylinder 9 mounted on the U-shaped plate 8. The drying mechanism is used to remove moisture from the surface of vegetables, greatly improving the uniformity of drying and avoiding the problems of localized under-drying and over-drying.

[0022] In this embodiment, during the vegetable washing process, the vegetables to be washed are placed at the rear of the conveyor 1. The conveyor 1 then starts and moves the baffle 3, which in turn propels the vegetables forward. When the vegetables reach the middle of the conveyor 1, the conveyor pipe 6 sprays water from an external water source, directly washing the surface of the vegetables. The kinetic energy of the water flow quickly washes away impurities such as mud, dust, insect eggs, and insect droppings. The spray also rapidly lowers the surface temperature of the vegetables while replenishing surface moisture, maintaining their freshness and delaying wilting, yellowing, and softening due to dehydration. During the washing process, the cylinder 9 starts and moves the fixed rod 10... The downward movement of the fixed rod 10 causes the rotating rod 11 to move downward, which in turn causes the connecting plate 12 to move downward. The downward movement of the connecting plate 12 pushes the conveying pipe 6 to rotate, which in turn causes the spray pipe 7 to rotate. This changes the direction of the water jet, allowing the water to be sprayed from different directions to clean the fruits and vegetables. This allows the direction and coverage of the water jet to be flexibly adjusted according to the conveying posture and the thickness of the pile of fruits and vegetables, so that the water can accurately cover all surfaces of the fruits and vegetables, achieving three-dimensional and multi-angle cleaning. This can not only wash away surface dust, but also penetrate into crevices and dead corners, thereby improving the overall thoroughness and uniformity of cleaning and preventing the problem of incomplete cleaning in some areas.

[0023] The drying mechanism also includes a fixed rod 10 mounted on the cylinder 9, a rotating rod 11 mounted on the fixed rod 10, and a connecting plate 12 mounted on the rotating rod 11. Moving the fixed rod 10 downwards causes the rotating rod 11 to move downwards, which in turn causes the connecting plate 12 to move downwards. The downward movement of the connecting plate 12 pushes the conveying pipe 6 to rotate. Other components include a hinge plate 17 mounted on the rotating rod 11, a chamfered plate 13 mounted on the conveyor table 1, a rotating rod 14 mounted on the chamfered plate 13, and a connecting plate 15 mounted on the rotating rod 9. The hot air blower 15 on the rotating rod 3 14 and the connecting plate 2 16 installed on the rotating rod 3 14 are used to blow hot air onto the surface of fruits and vegetables. The connecting plate 2 16 is connected to the hinge plate 17, and the conveying pipe 6 is connected to the connecting plate 1 12. The hot air blower 15 has at least one front hot air blower 15 with a relative interval at the front. During operation, the rotating rod 3 14 will drive the hot air blower 15 to rotate to improve the drying effect and increase the sweeping area of ​​the hot air. It can continuously change the air outlet angle and coverage area, so that the fruits and vegetables are in a flat, stacked, and flipped state.

[0024] In addition, after the fruits and vegetables are cleaned, the conveyor 1 will continue to move the fruits and vegetables forward. When the fruits and vegetables move to the front shoe surface position, the hot air blower 15 will start and blow hot air at the same time. At the same time, the rotating rod 11 moves downward and pulls the hinge plate 17 to move. The movement of the hinge plate 17 will drive the connecting plate 16 to rotate. The rotation of the connecting plate 16 will drive the rotating rod 14 to rotate. The rotation of the rotating rod 14 will drive the hot air blower 15 to swing, thereby increasing the sweeping area of ​​the hot air and continuously changing the air outlet angle and coverage area. This ensures that the hot air is evenly applied to each surface when the fruits and vegetables are laid flat, stacked, or turned over, greatly improving the drying uniformity and avoiding the problem of some areas not being dry or some areas being too dry. At the same time, when the fruits and vegetables enter the drying area, the water on the surface of the fruits and vegetables will drip off through the water leakage strip opened in the conveyor 1.

[0025] Example 2: Please see Figures 4-5 Based on the above embodiments, in another embodiment of the present invention, the drying mechanism further includes a cleaning mechanism 18 installed on the conveyor table 1. The cleaning mechanism 18 includes a rotating shaft 181 installed on the conveyor table 1. The conveyor table 1 will contact the transmission wheel 182, so that friction is generated between the transmission wheel 182 and the conveyor table 1, so that the transmission wheel 182 can rotate through the friction. The transmission wheel 182 installed on the rotating shaft 181 and the brush plate 183 installed on the rotating shaft 181. When the brush plate 183 rotates, it will contact the surface of the fruit and vegetables, so as to directly peel off and clean the stubborn impurities on the surface of the fruit and vegetables. The transmission wheel 182 is in contact with the conveyor 1. During operation, the conveyor 1 drives the transmission wheel 182 to rotate. The brush plate 183 is used to clean the surface of fruits and vegetables, solving stubborn dirt that cannot be handled by spray cleaning and significantly improving the thoroughness of cleaning. At the same time, the brush can make deep contact with hard-to-clean areas such as dents and around the stems of fruits and vegetables.

[0026] In this embodiment, during the conveying process, the conveyor 1 will contact the transmission wheel 182, generating friction between the transmission wheel 182 and the conveyor 1. This friction causes the transmission wheel 182 to rotate, which in turn drives the rotating shaft 181 to rotate. The rotation of the rotating shaft 181 will then drive the brush plate 183 to rotate. When the brush plate 183 rotates, it will contact the surface of the fruits and vegetables, thereby directly peeling off and cleaning the stubborn impurities on the surface of the fruits and vegetables. This solves the problem of stubborn dirt that cannot be handled by spray cleaning, significantly improving the thoroughness of cleaning. At the same time, for hard-to-clean areas such as crevices and around the stems of fruits and vegetables, the brush can make deep contact, improving the overall cleaning effect.

[0027] The cleaning mechanism 18 also includes an L-shaped plate 184 mounted on the conveyor 1, a sliding rod 185 mounted on the L-shaped plate 184, a beveled plate 186 mounted on the sliding rod 185, and a semi-circular block 187 mounted on the baffle 3. A spring is provided between the beveled plate 186 and the L-shaped plate 184. When the sliding rod 185 moves upward, it compresses the spring on the surface of the sliding rod 185. After the semi-circular block 187 passes the beveled plate 186, the sliding rod 185 moves downward by the elastic force of the spring.

[0028] The conveyor 1 and the inclined plate 186 are in contact with each other. When the inclined plate 186 moves downward, it will contact the surface of the conveyor 1 and then generate an impact force on the conveyor 1, causing the conveyor 1 to vibrate. The spring is used to push the inclined plate 186 to reset. The inclined plate 186 is used to shake off the water droplets on the surface of fruits and vegetables, and can significantly reduce the moisture content on the surface of fruits and vegetables, shorten the drying time and improve the drying effect of fruits and vegetables.

[0029] During the cleaning process of fruits and vegetables, the movement of the baffle 3 will cause the semicircular block 187 to move. During the movement of the semicircular block 187, it will come into contact with the inclined plate 186. Then, the pressure will force the inclined plate 186 to move upward. The upward movement of the inclined plate 186 will cause the sliding rod 185 to move upward. When the sliding rod 185 moves upward, it will compress the spring set on the surface of the sliding rod 185. After the semicircular block 187 passes the inclined plate 186, the sliding rod 185 will move downward by the elastic force of the spring. Then, it will drive the inclined plate 186 to move downward in sync. The downward movement of the inclined plate 186 will come into contact with the surface of the conveyor table 1. Then, it will generate an impact force on the conveyor table 1, causing the conveyor table 1 to shake. After the conveyor table 1 shakes, the water droplets on the surface of the fruits and vegetables will be further shaken off. This can work in conjunction with the hot air blower 15 to dehydrate the fruits and vegetables, and can significantly reduce the moisture content on the surface of the fruits and vegetables, reduce the drying pressure of the hot air blower 15, shorten the drying time, and improve the drying effect of the fruits and vegetables.

[0030] In this embodiment, it should be noted that a water supply device, a processor, and a power supply device may also be provided. The water supply device supplies water to the delivery pipe 6 and the spray pipe 7, and the processor controls the conveyor 1 and the cylinder 9. As one embodiment, the power supply device can be a storage battery or a municipal power supply device, the water supply device can be a municipal water supply device, and the processor is an existing device, which will not be described in detail in this embodiment. In this embodiment, the electrical connection of each device is made in a conventional way.

[0031] Example 3: Please see Figures 6-7Based on the above embodiments, in another embodiment of the present invention, the cleaning mechanism 18 further includes a flipping mechanism 19 installed on the conveyor table 1. The flipping mechanism 19 includes a flipping plate 191 installed on the inclined plate 186, a rounded corner plate 192 installed on the conveyor table 1, a sieve frame 193 installed on the rounded corner plate 192, and a protruding strip 198 installed on the sieve frame 193. The flipping plate 191 is used to flip the fruits and vegetables. When the flipping plate 191 moves upward, the fruits and vegetables will slide down the inclined surface of the flipping plate 191. When they fall, one side of the vegetables will contact the conveyor table 1 and be forced to flip by the forward movement force of the conveyor table 1. This can eliminate the drying blind spot, make the fruits and vegetables evenly heated and aired on both sides, and improve the drying uniformity and drying efficiency.

[0032] In this embodiment, during the fruit and vegetable drying process, the upward movement of the inclined plate 186 causes the flip plate 191 to move upward. As the conveyor 1 moves the fruit and vegetables, they come into contact with the surface of the flip plate 191. Subsequently, the fruit and vegetables are pushed onto the surface of the flip plate 191 by the pushing force of the conveyor 1. At the same time, as the flip plate 191 moves upward, the fruit and vegetables slide down the inclined surface of the flip plate 191. When they fall, one side of the vegetable comes into contact with the conveyor 1, and the forward movement of the conveyor 1 forces the vegetable to flip over, thus completing the action of flipping the vegetable or rotating the fruit. This prevents the leaves from piling up and causing the hot air to blow only on one side of the vegetable, resulting in uneven drying. It can eliminate drying blind spots, allowing the fruit and vegetables to be heated and aired evenly on both sides, improving drying uniformity and efficiency, reducing energy consumption, avoiding local overheating damage to the fruit and vegetables, ensuring the appearance and nutritional quality of the fruit and vegetables, and loosening the stacked materials to reduce fruit and vegetable damage, facilitating subsequent unloading and packaging, reducing the risk of spoilage caused by uneven moisture content, and extending the shelf life of the fruit and vegetables.

[0033] The flipping mechanism 19 also includes a slant bar 194 mounted on the conveyor table 1, a perforated plate 195 mounted on the slant bar 194, an elastic rod 196 mounted on the perforated plate 195, and a push plate 197 mounted on the elastic rod 196. A spring is provided between the push plate 197 and the perforated plate 195. The push plate 197 is used to reset the sieve frame 193. When the push plate 197 moves downward, it will drive the elastic rod 196 to move downward and compress the spring on the surface of the elastic rod 196. The push plate 197 and the sieve frame 193 are in contact with each other. The holes provided on the surface of the sieve frame 193 are used to screen fruits that are not up to size, thereby enabling the fruits to be graded by size and avoiding uneven processing. The flipping plate 191 is in contact with the conveyor table 1.

[0034] After drying, the fruits and vegetables fall onto the surface of the sieve frame 193, impacting it and forcing it to rotate downwards. This downward rotation causes the raised strip 198 to rotate, which in turn exerts pressure on the push plate 197, causing it to move downwards. This downward movement of the push plate 197 then causes the elastic rod 196 to move downwards, compressing the spring on its surface. Subsequently, the elastic rod 196, through the spring, drives the push plate 197 upwards, which in turn causes the sieve frame 193 to rotate. This allows the sieve frame 193 to oscillate, and during this oscillation, fruits of different sizes are sieved through the holes on its surface. This enables fruit grading by size, preventing uneven processing, improving the overall quality of fruit processing, and eliminating the need for manual sorting, thus reducing labor costs.
