Description

Technical Field

[0001] This invention belongs to the field of solid waste treatment, specifically a waste fruit recycling and treatment device. Background Technology

[0002] Many fruits may develop cosmetic defects during harvesting, transportation, or storage, such as damaged skin, irregular shape, or uneven color. Although these fruits are of good quality, they do not meet the sales standards of supermarkets or markets and are therefore discarded.

[0003] If discarded fruit is directly landfilled, it will occupy a lot of land resources, so it is necessary to recycle and process discarded fruit. Discarded fruit is rich in a variety of active ingredients, such as polyphenols, pectin, and vitamins. Through recycling and processing, these ingredients can be extracted and used in finished products such as feed and fuel.

[0004] Traditional methods of recycling waste fruit often involve simply crushing the fruit into pulp and then transporting the pulp to active extraction or fermentation equipment for recycling. However, the pulp residue contains a lot of moisture, which, if not removed, not only increases the transportation weight and costs, but also makes it difficult to preserve and process in subsequent steps such as grinding and extraction.

[0005] Therefore, the present invention provides a waste fruit recycling and processing device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The waste fruit recycling and processing device of the present invention includes a crushing box and a processing box. The processing box is fixed to the bottom of the crushing box and communicates with the crushing box. Two meshing toothed rollers are installed inside the crushing box. A drive box for driving the toothed rollers to rotate is installed on the outside of the crushing box. Two horizontally movable extrusion seats are arranged inside the processing box. Multiple leakage holes are opened on the bottom surface of the processing box. A discharge port is opened in the middle of the bottom surface of the processing box. A sealing gate that can be opened and closed is installed in the discharge port. Multiple nozzles one and multiple nozzles two are respectively installed on the opposite surfaces of the two extrusion seats. Two connecting pipes for transmitting fluid to nozzles one and nozzles two are connected to the opposite surfaces of the two extrusion seats.

[0008] Fruits requiring recycling are placed into the crushing chamber from top to bottom. A drive unit rotates two toothed rollers, squeezing the fruit towards the center of the rollers. The crushed fruit residue then enters the processing chamber under gravity. The residue falls between two pressing seats, which are intermittently controlled to converge towards the center, further squeezing the residue. During this squeezing process, the juice in the residue drains downwards through a drain hole at the bottom. The pressing seats stop squeezing after reaching a certain point, allowing the crushing chamber to continue operating normally. The falling residue temporarily rests above the pressing seats, and when the pressing seats separate, it falls back between them. Once the residue is squeezed into flakes, these flakes are positioned directly above the discharge port. As the pressing seats separate, the squeezed flakes are discharged from the discharge port under gravity. This design effectively removes water from the fruit residue, reducing its weight during transport and facilitating subsequent recycling.

[0009] When further drying or cleaning of the residue is required in subsequent recycling processes, after the residue is compressed into flakes, the connecting pipes on both sides are connected to the water supply equipment and the air supply equipment, respectively. The water supply equipment injects clean water through the connecting pipes and nozzles between the two extrusion seats. Excess water is discharged from the bottom outlet. Continuous rinsing removes dust and other impurities adhering to the surface of the residue. This step can also be performed simultaneously at the start of extrusion. For some firmly attached organic impurities, such as grease and pectin residue, alkaline washing can be used. In this case, the residue is first compressed into flakes, but not to the final stage. It is sufficient to ensure that all leaks in the extrusion seats are blocked at this point. Then, the sealing gate is closed, and the alkaline solution is injected. The residue is mixed with the rinsing fluid in the compression chamber and soaked for a period of time. Then, the sealed gate is opened to release the solution, and the compression process is repeated. This removes most of the unwanted components from the fruit residue, which is helpful for subsequent steps such as extracting pectin from the fruit residue and further processing the residue into feed. After rinsing and compression, an air supply device blows air through nozzles onto the residue to remove moisture from the surface, achieving a drying effect. High-temperature airflow can be used to further enhance the drying effect. This setup achieves solid-liquid separation of the fruit residue and can produce residues of different degrees according to different needs, effectively transforming the original solid waste into useful materials and achieving a highly efficient recycling process.

[0010] Preferably, horizontally arranged insert plates are fixed to the upper part of the opposite surfaces of the two extrusion seats. The two insert plates are at different horizontal heights. The surface of the extrusion seat is provided with an insertion groove that matches the insert plate. During operation, the insert plates and insertion grooves create an extrusion space below the insert plates that is isolated from the upper part when the two extrusion seats are combined. This prevents water from overflowing upwards even if the rinsing water flow is too large. In the subsequent drying process, the airflow will only be discharged from the bottom and will not affect the operation above. It should be noted that the residue in the extrusion space should not be too much during the extrusion process. It is necessary to ensure that the insert plates and insertion grooves can be properly connected, and that the height of the residue does not exceed the insertion groove during connection to ensure the normal operation of the equipment.

[0011] Preferably, multiple rotatable stirring rods are arranged between the two extrusion seats. The stirring rods are horizontally positioned, and the surface of each extrusion seat has a recovery groove for fixing and retrieving the stirring rods. A protective cover made of elastic material is fixed to the surface of the recovery groove. During operation, after the first drying, the two extrusion seats are separated by a certain distance, but the insert plate must remain in an isolated and closed state. Then, the stirring rods are extended from the recovery groove and rotated to gradually break up the extruded residue from the bottom. As the bottom is broken up, the residue gradually concentrates at the bottom, thus performing secondary crushing of the already extruded residue. Then, it is extruded and dried again. Through this process of secondary crushing, drying, and extrusion, the residue that was originally in the center of the extrusion is exposed. In this state, airflow drying is performed first, and a partial sealing gate is opened to allow airflow to pass through, but the residue will not fall. This allows the parts that were not originally in contact with the airflow to fully contact the airflow, improving the drying effect. At the same time, the final extrusion can more effectively remove moisture. The protective cover is designed to prevent the residue from entering the recovery groove.

[0012] Preferably, the stirring rod comprises a flexible strip made of elastic material, with a counterweight embedded in the outer part of the middle of the strip. Metal rods are fixed to both ends of the strip. One recycling trough has a moving seat for horizontal movement of the strip, and the other recycling trough has a fixing ring for fixing and rotating the strip. During operation, when the stirring rod is needed, the moving seat pushes the entire stirring rod out of the recycling trough and inserts it into the recycling trough of the other extrusion seat. The fixing ring then secures its ends, placing the metal rods at the ends of the recycling troughs. The fixing ring rotates the entire stirring rod. Due to the elasticity of the strip and the presence of the counterweight, the strip's center of gravity shifts outward, causing it to rotate in an elliptical trajectory, thus breaking down and dispersing residue. When not in use, the entire strip can be recycled back into the recycling trough without occupying extrusion space. Furthermore, the strip has a simple structure, is not prone to failure, and can operate for extended periods.

[0013] Preferably, the moving base is equipped with electric wheels at both its upper and lower ends. The moving base is slidably engaged in the recycling tank. A horizontal rod is fixed to the end of the moving base, and the length of the horizontal rod is the same as the length of the flexible strip. The horizontal rod is inserted into the metal rod and the flexible strip. The end of the horizontal rod is made of magnetic material. During operation, the electric wheels drive the moving base to move horizontally in the recycling tank, thereby moving the horizontal rod. By pushing the horizontal rod outward, the entire stirring rod is pushed outward. The horizontal rod maintains the rigidity of the stirring rod, allowing it to effectively pass through the residue and enter another recycling tank. Then, a retaining ring is used to fix the other end. Afterward, the moving base retracts, allowing the horizontal rod to be pulled out of the flexible strip, thus not affecting the deformation and rotation of the flexible strip. When it is necessary to pull the stirring rod back, the horizontal rod is first reinserted into the flexible strip, allowing the magnetic material to attract the metal rod at the end. Then, the moving base pulls back, and the entire stirring rod is pulled back into the recycling tank by magnetic attraction and friction. This configuration achieves the control effect of the stirring rod, and the overall control process is simple and quick, requiring no complex execution procedures or parts.

[0014] Preferably, the fixing ring and the corresponding metal rod are equipped with matching electric buckles, and the end of the corresponding metal rod is set with a sharp angle. The fixing ring is rotatably engaged in the extrusion seat. A gear ring is fixed to the outside of the fixing ring, and an electric gear two meshes with the outside of the gear ring. During operation, the metal rod at the end is fixed by the electric buckle, and the fixing ring is rotated by the electric gear two, which in turn drives the entire stirring rod to rotate. The end of the horizontal rod will restrict the metal rod at the other end in the recycling tank, but it does not affect the rotation of the metal rod, ensuring the normal operation of the rotation process.

[0015] Preferably, the top of the crushing box is fixedly connected to a feeding platform, the bottom of the crushing box is provided with a drop opening, the top of the processing box is open, and both sides of the processing box are open. During operation, the waste fruit is fed into the middle of the two toothed rollers through the opening in the middle of the feeding platform. The drop opening is to ensure that the crushed residue is concentrated in the processing box. The openings on both sides of the processing box are for the convenience of connecting the transmission pipe and the normal movement of the extrusion seat.

[0016] Preferably, both sides of the extrusion seat are provided with transmission tooth grooves, and an electric gear is engaged on the outer side of the transmission tooth groove. During operation, the horizontal movement of the extrusion seat can be controlled by the rotation of the electric gear. Ball bearings can be installed at the bottom of the extrusion seat to reduce friction.

[0017] Preferably, a transmission pipe connected to the connecting pipe is installed on the opposite surfaces of the two extrusion seats. The transmission pipe is made of metal and is flat. Multiple nozzles are fixed to the bottom of the lowest insert plate, and multiple nozzles are distributed on one of the transmission pipes and connected to the transmission pipe. During operation, the high-temperature airflow passes through the transmission pipe first during the drying process, thereby heating the surface of the transmission pipe. The residue is heated by contact heat transfer, which assists the airflow drying process. The nozzles are located at the bottom of the insert plate, which not only allows the drying airflow to effectively pass through the residue from top to bottom, but also helps the residue to fall quickly when the sealing gate is fully opened after drying. The dispersed nozzles can effectively and quickly inject liquid and ensure that the liquid contacts the residue from multiple contact points, quickly soaking the residue.

[0018] Preferably, the connecting pipe is spiral-shaped and made of elastic material. A recovery cylinder for recovering the connecting pipe is fixedly connected to the opposite sides of the two extrusion seats. An outwardly extending support frame is fixedly connected to the outside of the processing box. A transmission valve communicating with the connecting pipe is fixedly connected to the support frame. During operation, the connecting pipe needs to be adaptively stretched and shortened as the extrusion seats move. The spiral-shaped and elastic connecting pipe can ensure that it maintains its shape during stretching and shortening, reducing problems such as entanglement. The recovery cylinder is used to temporarily store the connecting pipe, and the transmission valve is used to connect the airflow and water flow equipment.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The waste fruit recycling and processing device of the present invention intermittently controls two extrusion seats to converge towards the center, thereby extruding the residue. During the extrusion process, the juice rich in the residue will be discharged downward through the drain hole at the bottom. After the two extrusion seats have extruded to a certain extent, they stop extruding, and the crushing box above can work normally. The fallen residue will temporarily fall above the extrusion seats, and when the extrusion seats separate, it will fall back between the two extrusion seats. When the residue is extruded into flakes, the flakes of residue will be just above the discharge port. As the extrusion seats separate, the extruded flakes of residue will be discharged from the discharge port under the action of gravity. Through this setting, water removal treatment of fruit residue is realized, which not only reduces the weight of the residue during subsequent transportation, but also assists the subsequent recycling process of the residue.

[0021] 2. The waste fruit recycling and processing device of the present invention injects clean water into the space between two extrusion seats through a water supply device via a connecting pipe and a nozzle. Excess water is discharged from the bottom outlet. With continuous rinsing, dust and other impurities attached to the surface of the residue can be removed. This step can also be carried out simultaneously at the start of extrusion. An air supply device blows airflow onto the residue through a nozzle to remove moisture from the surface of the residue, achieving a drying effect. High-temperature airflow can be used to further enhance the drying effect. Through this setup, solid-liquid separation of fruit residue is achieved, and residue of different degrees can be produced according to different needs, effectively transforming the original solid waste into useful materials and achieving a highly efficient recycling and processing effect.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 7 As shown in the embodiment of the present invention, a waste fruit recycling and processing device includes a crushing box 1 and a processing box 2. The processing box 2 is fixed to the bottom of the crushing box 1 and communicates with the crushing box 1. Two meshing toothed rollers 3 are installed inside the crushing box 1. A drive box 5 for driving the toothed rollers 3 to rotate is installed on the outside of the crushing box 1. Two horizontally movable extrusion seats 10 are provided inside the processing box 2. Multiple leakage holes 9 are opened on the bottom surface of the processing box 2. A discharge port 15 is opened in the middle of the bottom surface of the processing box 2. A sealing gate 16 that can be opened and closed is installed in the discharge port 15. Multiple nozzles 18 and multiple nozzles 22 are respectively installed on the opposite surfaces of the two extrusion seats 10. Two connecting pipes 8 for transmitting fluid to the nozzles 18 and nozzles 22 are connected to the opposite surfaces of the two extrusion seats 10.

[0033] The fruit to be recycled is placed into the crushing box 1 from top to bottom. The drive box 5 rotates the two toothed rollers 3, squeezing the fruit towards the center of the rollers. After crushing, the residue enters the processing box 2 under gravity. The residue falls between two pressing seats 10. The two pressing seats 10 are intermittently controlled to converge towards the center, thus squeezing the residue. During squeezing, the juice in the residue is discharged downwards through the drain hole 9 at the bottom. The two pressing seats 10 stop squeezing after reaching a certain point. The crushing box 1 can work normally. The falling residue will temporarily fall above the extrusion seat 10. When the extrusion seat 10 separates, it will fall back between the two extrusion seats 10. After the residue is extruded into flakes, the flakes will be just above the discharge port 15. As the extrusion seat 10 separates, the extruded flakes will be discharged from the discharge port 15 under the action of gravity. Through this setting, water treatment of fruit residue is realized, which not only reduces the weight of subsequent transportation of residue, but also assists in the subsequent recycling process of residue.

[0034] When further drying or cleaning of the residue is required in subsequent recycling processes, after the residue is compressed into flakes, the connecting pipes 8 on both sides are connected to the water supply device and the air supply device respectively. The water supply device injects clean water through the connecting pipes 8 and nozzle 22 into the space between the two extrusion seats 10. Excess water is discharged from the bottom outlet 15. Continuous rinsing removes dust and other impurities adhering to the surface of the residue. This step can also be performed simultaneously at the start of extrusion. For some firmly attached organic impurities, such as grease and pectin residue, alkaline washing can be used. In this case, the residue is first compressed into flakes, but not to the final stage. It is sufficient to ensure that the extrusion seats 10 have blocked all the leaks 9. Then, the sealing gate 16 is closed, and the alkaline solution... The liquid is injected into the extrusion space and mixed with the residue. After soaking for a period of time, the sealed gate 16 is opened to release the solution, and the horizontal extrusion process is repeated. This removes most of the unwanted components from the fruit residue, which is helpful for subsequent steps such as extracting pectin from the fruit residue and further processing the residue into feed. After rinsing and extrusion, airflow is blown onto the residue through nozzle 18 by the airflow supply device to remove the moisture on the surface of the residue and achieve a drying effect. High-temperature airflow can be used to further enhance the drying effect. Through this setup, the solid-liquid separation effect of the fruit residue is achieved, and residues of different degrees can be produced according to different needs, effectively transforming the original solid waste into useful materials and achieving a highly efficient recycling and processing effect.

[0035] like Figures 1 to 7 As shown, horizontally arranged insert plates 17 are fixedly connected to the upper part of the opposite surfaces of the two extrusion seats 10. The two insert plates 17 have different horizontal heights, and the surface of the extrusion seat 10 is provided with an insertion groove that matches the insert plate 17.

[0036] During operation, the insertion plate 17 and the mating slot create a compression space below the insertion plate 17 that is isolated from the upper part when the two compression seats 10 are joined together. This prevents water from overflowing upwards even if the rinsing water flow is too large. In the subsequent drying process, the airflow will only be discharged from the bottom and will not affect the work above. It is important to note that there should not be too much residue in the compression space during the compression process. It is necessary to ensure that the insertion plate 17 and the mating slot can be properly connected, and that the height of the residue does not exceed the mating slot during connection to ensure the normal operation of the equipment.

[0037] A plurality of rotatable stirring rods 20 are provided between the two extrusion seats 10. The stirring rods 20 are arranged horizontally. The surface of the extrusion seat 10 is provided with a recycling groove 19 for fixing and recycling the stirring rods 20. The surface of the recycling groove 19 is fixed with a protective cover of elastic material.

[0038] During operation, after the first drying, the two extrusion seats 10 are separated by a certain distance, but the insert plate 17 must remain in an isolated and closed state. Then, the stirring rod 20 extends from the recovery tank 19 and rotates to gradually break up the extruded residue from the bottom. As the bottom is broken up, the residue gradually concentrates at the bottom, thus performing secondary crushing of the already extruded residue. Then, it is extruded and dried again. Through this process of secondary grinding, drying, and extrusion, the residue that was originally in the center of the extrusion is exposed. In this state, airflow drying is performed first, and the partially sealed gate 16 is opened to allow airflow to pass through, but the residue will not fall. This allows the parts that were not originally in contact with the airflow to fully contact the airflow, improving the drying effect. At the same time, the final extrusion can more effectively remove moisture. The protective cover is set to prevent the residue from entering the recovery tank 19.

[0039] The stirring rod 20 includes a flexible strip 23 made of elastic material. A counterweight is embedded in the middle of the flexible strip 23 on the outer side. Metal rods 24 are fixed to both ends of the flexible strip 23. A moving seat 28 for driving the flexible strip 23 to move horizontally is provided in one of the recycling troughs 19. A fixing ring 29 for fixing and driving the flexible strip 23 to rotate is provided in the other recycling trough 19.

[0040] When the stirring rod 20 is needed during operation, the entire stirring rod 20 is pushed out of the recycling tank 19 by the moving seat 28, and then inserted into the recycling tank 19 of another extrusion seat 10. The end of the rod is fixed by the retaining ring 29. At this time, the positions of the two metal rods 24 are exactly at the ends of the recycling tank 19. The retaining ring 29 drives the entire stirring rod 20 to rotate. Due to the elastic material of the soft strip 23 and the setting of the configuration block, the center of gravity of the soft strip 23 shifts outward. When rotating, the soft strip 23 will form an elliptical rotation trajectory, thereby breaking down and dispersing the residue. At the same time, when not in use, it can be completely recycled back into the recycling tank 19 without occupying the extrusion space. Moreover, the soft strip 23 has a simple structure, is not prone to failure, and can work for a long time.

[0041] Both ends of the movable seat 28 are equipped with electric wheels. The movable seat 28 is slidably engaged in the recycling trough 19. A horizontal rod 27 is fixedly connected to the end of the movable seat 28. The length of the horizontal rod 27 is the same as the length of the flexible strip 23. The horizontal rod 27 is inserted into the metal rod 24 and the flexible strip 23. The end of the horizontal rod 27 is made of magnetic material.

[0042] During operation, the electric wheel drives the moving seat 28 to move horizontally in the recycling tank 19, which in turn moves the horizontal rod 27. By pushing the horizontal rod 27 outward, the entire stirring rod 20 is pushed outward. The horizontal rod 27 maintains the rigidity of the stirring rod 20, which can effectively pass through the residue and enter another recycling tank 19. Then, the other end is fixed with the retaining ring 29. Afterward, the moving seat 28 retracts, allowing the horizontal rod 27 to be pulled out of the flexible strip 23. This does not affect the deformation and rotation of the flexible strip 23. When it is necessary to pull back the stirring rod 20, the horizontal rod 27 is first reinserted into the flexible strip 23, allowing the magnetic material to attract the metal rod 24 at the end. Then, the moving seat 28 pulls back, and the entire stirring rod 20 is pulled back into the recycling tank 19 through magnetic attraction and friction. Through this setting, the stirring rod 20 is controlled, and the overall control process is simple and quick, without the need for complicated execution procedures and parts.

[0043] The fixed ring 29 and the corresponding metal rod 24 are equipped with matching electric buckles 26, and the end of the corresponding metal rod 24 is set with a sharp angle. The fixed ring 29 is rotatably engaged in the pressing seat 10. A gear ring is fixedly connected to the outside of the fixed ring 29, and an electric gear 30 is meshed on the outside of the gear ring.

[0044] During operation, the metal rod 24 at one end is fixed by the electric buckle 26, and the fixing ring 29 is rotated by the electric gear 20, which in turn drives the entire stirring rod 20 to rotate. The end of the horizontal rod 27 will restrict the metal rod 24 at the other end in the recycling tank 19, but it does not affect the rotation of the metal rod 24, thus ensuring the normal operation of the rotation process.

[0045] The top of the crushing box 1 is fixedly connected to the feeding platform 4, the bottom of the crushing box 1 is provided with a drop opening 14, the top of the processing box 2 is open, and both sides of the processing box 2 are open.

[0046] During operation, waste fruit is fed into the middle of the two toothed rollers 3 through the opening in the middle of the feeding platform 4. The drop opening 14 is to ensure that the crushed residue is concentrated in the processing box 2. The openings on both sides of the processing box 2 are for the connection of the transmission pipe 21 and the normal movement of the extrusion seat 10.

[0047] Both sides of the extrusion seat 10 are provided with transmission tooth grooves 11, and an electric gear 12 meshes with the outer side of the transmission tooth grooves 11.

[0048] During operation, the horizontal movement of the extrusion seat 10 can be controlled by rotating the electric gear 12. Ball bearings can be installed at the bottom of the extrusion seat 10 to reduce friction.

[0049] A transmission pipe 21 connected to the connecting pipe 8 is installed on the opposite surfaces of the two extrusion seats 10. The transmission pipe 21 is made of metal and is flat. Multiple nozzles 18 are fixed to the bottom of the bottommost insert plate 17, and multiple nozzles 22 are distributed on one of the transmission pipes 21 and connected to the transmission pipe 21.

[0050] During operation, the high-temperature airflow first passes through the transmission pipe 21 during the drying process, thereby heating the surface of the transmission pipe 21. The residue is heated through contact heat transfer, which assists the airflow drying process. The nozzle 18 is located at the bottom of the insert plate 17, which not only allows the drying airflow to effectively pass through the residue from top to bottom, but also helps the residue to fall quickly when the sealing gate 16 is fully opened after drying is completed, thanks to the action of the airflow. The dispersed nozzle 22 can effectively and quickly inject liquid and ensure that the liquid contacts the residue from multiple contact points, quickly soaking the residue.

[0051] The connecting pipe 8 is spiral-shaped and made of elastic material. A recycling cylinder 13 for recycling the connecting pipe 8 is fixedly connected to the opposite sides of the two extrusion seats 10. An outwardly extending support frame 6 is fixedly connected to the outside of the processing box 2. A transmission valve 7 communicating with the connecting pipe 8 is fixedly connected to the support frame 6.

[0052] During operation, as the extrusion seat 10 moves, the connecting pipe 8 needs to be adapted to be stretched and shortened. The spiral and elastic material of the connecting pipe 8 ensures that it maintains its shape during stretching and shortening, reducing problems such as entanglement. The recovery cylinder 13 is used to temporarily store the connecting pipe 8, and the transmission valve 7 is used to connect the airflow and water flow equipment.

[0053] During operation, the fruit to be recycled is placed into the crushing box 1 from top to bottom. The drive box 5 drives the two toothed rollers 3 to rotate, squeezing the fruit towards the center of the two toothed rollers 3. After crushing, the residue enters the processing box 2 under gravity. The residue falls between the two pressing seats 10. The two pressing seats 10 are intermittently controlled to converge towards the center, thereby squeezing the residue. During the squeezing process, the juice in the residue is discharged downward through the drain hole 9 at the bottom. The two pressing seats 10 stop squeezing after squeezing to a certain extent. The crushing box 1 above can work normally. The falling residue will temporarily fall above the extrusion seat 10. When the extrusion seat 10 separates, it will fall back between the two extrusion seats 10. After the residue is extruded into flakes, the flakes will be just above the discharge port 15. As the extrusion seat 10 separates, the extruded flakes will be discharged from the discharge port 15 under the action of gravity. Through this setting, water treatment of fruit residue is realized, which not only reduces the weight of subsequent transportation of residue, but also assists in the subsequent recycling process of residue.

[0054] When further drying or cleaning of the residue is required in subsequent recycling processes, after the residue is compressed into flakes, the connecting pipes 8 on both sides are connected to the water supply device and the air supply device respectively. The water supply device injects clean water through the connecting pipes 8 and nozzle 22 into the space between the two extrusion seats 10. Excess water is discharged from the bottom outlet 15. Continuous rinsing removes dust and other impurities adhering to the surface of the residue. This step can also be performed simultaneously at the start of extrusion. For some firmly attached organic impurities, such as grease and pectin residue, alkaline washing can be used. In this case, the residue is first compressed into flakes, but not to the final stage. It is sufficient to ensure that the extrusion seats 10 have blocked all the leaks 9. Then, the sealing gate 16 is closed, and the alkaline solution... The liquid is injected into the extrusion space and mixed with the residue. After soaking for a period of time, the sealed gate 16 is opened to release the solution, and the horizontal extrusion process is carried out again. This removes most of the unwanted components from the fruit residue, which is helpful for subsequent steps such as extracting pectin from the fruit residue and further processing the residue to make feed. After rinsing and extrusion, the air supply equipment blows airflow onto the residue through nozzle 18 to remove the moisture on the surface of the residue, achieving a drying effect. High-temperature airflow can be used to further enhance the drying effect. Through this setting, the solid-liquid separation effect of the fruit residue is achieved, and residues of different degrees can be produced according to different needs, effectively transforming the original solid waste into useful materials and achieving a highly efficient recycling and treatment effect.

[0055] By using the insert plate 17 and the insertion slot, when the two extrusion seats 10 are combined, an extrusion space isolated from the upper part can be formed below the insert plate 17. This way, even if the rinsing water flow is too large, it will not overflow upwards. At the same time, during the subsequent drying process, the airflow will only be discharged from the bottom and will not affect the work above. It should be noted that there should not be too much residue in the extrusion space during the extrusion process. It is necessary to ensure that the insert plate 17 and the insertion slot can be properly connected. At the same time, when connected, the height of the residue will not exceed the insertion slot to ensure the normal operation of the equipment.

[0056] After the first drying, the two extrusion seats 10 are separated by a certain distance, but the insert plate 17 must remain in an isolated and sealed state. Then, the stirring rod 20 extends from the recovery tank 19 and rotates to gradually break up the extruded residue from the bottom. As the bottom is broken up, the residue gradually concentrates at the bottom, thus performing secondary crushing of the already extruded residue. Then, it is extruded and dried again. Through this process of secondary grinding, drying, and extrusion, the residue that was originally in the center of the extrusion is exposed. In this state, airflow drying is performed first, and the sealing gate 16 is partially opened to allow airflow to pass through, but the residue will not fall. This allows the parts that were not originally in contact with the airflow to fully contact the airflow, improving the drying effect. At the same time, the final extrusion can more effectively remove moisture. The protective cover is set to prevent the residue from entering the recovery tank 19.

[0057] When the stirring rod 20 is needed, the entire stirring rod 20 is pushed out of the recycling tank 19 by the moving seat 28, and then inserted into the recycling tank 19 of another extrusion seat 10. The end of the rod is fixed by the retaining ring 29. At this time, the positions of the two metal rods 24 are exactly at the ends of the recycling tank 19. The retaining ring 29 drives the entire stirring rod 20 to rotate. Due to the elastic material of the soft strip 23 and the setting of the configuration block, the center of gravity of the soft strip 23 shifts outward. When rotating, the soft strip 23 will form an elliptical rotation trajectory, thereby breaking down and dispersing the residue. At the same time, when not in use, it can be completely recycled back into the recycling tank 19 without occupying the extrusion space. Moreover, the soft strip 23 has a simple structure, is not prone to failure, and can work for a long time.

[0058] The electric wheel drives the moving seat 28 to move horizontally in the recycling tank 19, which in turn moves the horizontal rod 27. By pushing the horizontal rod 27 outward, the entire stirring rod 20 is pushed outward. The horizontal rod 27 maintains the rigidity of the stirring rod 20, which can effectively pass through the residue and enter another recycling tank 19. Then, the other end is fixed with the retaining ring 29. After that, the moving seat 28 retracts, allowing the horizontal rod 27 to be pulled out of the flexible strip 23. This does not affect the deformation and rotation of the flexible strip 23. When it is necessary to pull back the stirring rod 20, the horizontal rod 27 is first reinserted into the flexible strip 23, allowing the magnetic material to attract the metal rod 24 at the end. Then, the moving seat 28 pulls back, and the entire stirring rod 20 is pulled back into the recycling tank 19 through magnetic attraction and friction. Through this setting, the stirring rod 20 can be controlled, and the overall control process is simple and quick, without the need for complicated execution procedures and parts.

[0059] The metal rod 24 at the end is fixed by the electric buckle 26, and the fixing ring 29 is rotated by the electric gear 20, which in turn drives the entire stirring rod 20 to rotate. The end of the horizontal rod 27 will restrict the metal rod 24 at the other end in the recycling tank 19, but it does not affect the rotation of the metal rod 24, thus ensuring the normal operation of the rotation process.

[0060] Waste fruit is fed into the middle of the feeding platform 4 through the opening in the middle of the two toothed rollers 3. The drop outlet 14 is to ensure that the crushed residue is concentrated in the processing box 2. The openings on both sides of the processing box 2 are for the connection of the transmission pipe 21 and the normal movement of the extrusion seat 10.

[0061] The horizontal movement of the extrusion seat 10 can be controlled by rotating the electric gear 12. Ball bearings can be installed at the bottom of the extrusion seat 10 to reduce friction.

[0062] During the drying process, the high-temperature airflow first passes through the transmission pipe 21, thereby heating the surface of the transmission pipe 21. The residue is heated through contact heat transfer, which assists the airflow drying process. The nozzle 18 is located at the bottom of the insert plate 17, which not only allows the drying airflow to effectively pass through the residue from top to bottom, but also helps the residue to fall quickly when the sealing gate 16 is fully opened after drying. The dispersed nozzle 22 can effectively and quickly inject liquid and ensure that the liquid contacts the residue from multiple contact points, quickly soaking the residue.

[0063] During the movement of the extrusion seat 10, the connecting pipe 8 needs to be stretched and shortened adaptively. The connecting pipe 8, made of a spiral and elastic material, can ensure that it maintains its shape during stretching and shortening, reducing problems such as entanglement. The recovery cylinder 13 is used to temporarily store the connecting pipe 8, and the transmission valve 7 is used to connect the airflow and water flow equipment.
