Description

Technical Field

[0001] This invention relates to the field of fruit processing technology, specifically a process and apparatus for producing ready-to-eat fresh apples for a space station. Background Technology

[0002] As is widely known, apples eaten by astronauts on the space station must be fresh, clean, and sterile. This means the raw materials must be freshly picked fruit or fruit stored in a controlled atmosphere storage facility. The controlled atmosphere storage facility maintains an oxygen level of 2.0-4.0%, a carbon dioxide level of 0.5-1.2%, a temperature of 0-1℃, and a humidity level of 85-95%. Controlled atmosphere storage effectively ensures firmness, sugar content, and freshness, guaranteeing the shelf life at room temperature on the space station.

[0003] For apple packaging, it needs to be carried out in a sterile packaging room. The packaging boxes must be made of food-grade polyethylene hollow board material, and ozone + ultraviolet disinfection is required. Before the third-party microbial test is passed and meets the requirements, the apples need to be cleaned and disinfected. The specific process flow is as follows: Apples leaving the warehouse - online cleaning and disinfection - drying - sorting and weighing - cold storage - rinsing and drying - secondary disinfection - bagging - boxing and assembly - inspection - leaving the factory - transportation.

[0004] During the apple cleaning and disinfection process, it is necessary to remove impurities and pesticide residues from the surface of each apple. For example, the announcement number CN108283318B, dated April 21, 2020, entitled "An Apple Cleaning Device," includes a workbench with a storage bin, a cleaning mechanism, and a feeding mechanism arranged horizontally on it. The cleaning mechanism includes two rotating shafts and motors driving the shafts. Conveyor belts are located at both ends of the shafts, and several cleaning rollers are positioned between the two shafts. Support rods perpendicular to the surface of the conveyor belts are evenly distributed. A baffle is connected between the upper ends of two opposing support rods on the two conveyor belts, with a gap between the baffle and the conveyor belt. Water spray heads are located above the cleaning rollers, and a guide plate is positioned between the cleaning rollers and the conveyor belt below. The end of the guide plate closest to the storage bin is located between the rotating shaft and the storage bin. A gap exists between the guide plate and the cleaning roller for apples to pass through. A water tank is located below the conveyor belt. The feeding mechanism is located at the discharge end of the cleaning structure, and a clean water tank is located at the discharge end of the feeding mechanism. This solution enables the automatic selection and cleaning of apples.

[0005] The shortcomings of existing technology are that when cleaning freshly picked apples, the method of using water flow and a brush-brushed cleaning roller to clean impurities and pesticide residues on the apple surface is not feasible. During the cleaning process, the apple is not fixed in place, making it difficult to accurately clean every part. Moreover, the apple stem and calyx are concave, making these concave parts even more difficult to clean accurately. As a result, it is difficult to clean impurities and pesticide residues from the stem and calyx. This cleaning method is obviously flawed for apples intended for immediate consumption on a space station. Summary of the Invention

[0006] The purpose of this invention is to provide a process and apparatus for producing ready-to-eat fresh apples for space stations, thereby solving the technical problems in related technologies.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A processing device for ready-to-eat fresh apples for a space station includes a workbench and a cleaning device mounted on the workbench. The cleaning device includes a turning assembly, which includes a base and a first driving component that drives the base to rotate on the workbench. Multiple sets of support rollers are arranged circumferentially on the base, with two rollers in each set, and the apples are fixed by clamping. A second driving component is provided on the workbench to drive each set of support rollers to rotate. Under the drive of the second driving component, each set of support rollers moves in two ways: a first movement mode in which each set of support rollers rotates in the same direction, using friction to turn the apples in the opposite direction; and a second movement mode in which each set of support rollers moves axially, using friction to rub and turn the apples. The cleaning assembly washes the apples after each turning.

[0009] As mentioned above, the surface of the support roller is covered with a rubber sleeve, and based on the elastic deformation of the rubber sleeve, the two support rollers in each group clamp the apples to be washed.

[0010] As described above, the first driving component includes a driving source mounted on the workbench and an intermittent transmission mechanism. The power output end of the intermittent transmission mechanism is provided with a turntable, and the edge of the turntable is provided with multiple levers along the circumferential direction. The support roller is slidably arranged on the seat body along its own axial direction, and in the sliding direction, a first elastic element is provided between the support roller and the seat body. During the forward rotation stroke of the turntable driving the multiple levers, the seat body moves circumferentially, and each set of support rollers drives the apple to turn based on the driving action of the second driving component. During the reverse rotation stroke of the turntable driving the multiple levers, the multiple levers intermittently move each support roller along the axial direction.

[0011] As described above, each set of support rollers is provided with two baffles, the support rollers and the baffles are in movable contact, the part between the two baffles is used to place apples, and each baffle is fixedly connected to the base.

[0012] The cleaning assembly described above includes a cover plate fixed to the workbench, on which multiple transmission plates are arranged circumferentially. Each transmission plate is slidably arranged on the cover plate along the axial direction of the turntable. Each transmission plate is equipped with a brush corresponding to the position when the second drive member drives each set of support rollers to move. The transmission plate drives the brush to contact the apple based on the force of the intermittent transmission mechanism driving the turntable to rotate in the opposite direction.

[0013] As mentioned above, the brush is equipped with a nozzle, and a water pipe is connected to the nozzle. During the brushing process of washing the apple, the nozzle sprays cleaning liquid onto the apple.

[0014] The second driving component described above includes a gear at the end of each support roller and multiple sets of first racks arranged circumferentially on the worktable. Each set of first racks consists of two racks, and the distance between each set of first racks is equal to the distance between each set of support rollers in the circumferential direction. The positions of the two gears on each set of support rollers are offset radially from each other on the turntable. During the forward rotation stroke of the seat, the gears mesh with the first racks, and each set of support rollers rotates in the same direction, causing the apples to flip in the opposite direction.

[0015] As described above, the second driving component also includes a pressing block, which is disposed on a set of first racks in the middle position among multiple sets of first racks. When each set of support rollers and the pressing block form a mutual pressing action, one of the support rollers in each set moves axially to rub and flip the apple.

[0016] As described above, each set of supporting rollers, during its travel through the middle set of first racks among multiple sets of first racks, first rubs and flips the apple, and then drives the apple to flip in the opposite direction.

[0017] This invention also relates to a process for producing and processing ready-to-eat fresh apples for a space station. The method for processing apples using the aforementioned ready-to-eat fresh apple production and processing device for a space station includes the following steps:

[0018] Step 1, feeding: During the forward rotation of the seat body driven by the first drive component, the apples to be cleaned are fed into each set of conveyor rollers in sequence.

[0019] Step 2: Cleaning. The flipping component flips the apple multiple times at different angles. After each flip, the cleaning component cleans the apple.

[0020] Step 3, unloading: During the forward rotation of the seat driven by the first drive component, the cleaned apples are removed from each set of conveyor rollers in sequence.

[0021] The beneficial effects of this invention are as follows: by setting up a flipping component, the apple can be flipped at different angles during the apple washing process, so that every part of the apple can be cleaned by the washing component, thus improving the cleaning effect of the apple more effectively.

Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 To be continued Figure 5 The present invention will now be described in further detail.

[0031] One embodiment of the present invention relates to a processing device for ready-to-eat fresh apples for a space station, including a workbench 1 and a cleaning device disposed on the workbench 1. The cleaning device includes: a turning assembly, which includes a base 2 and a first driving member that drives the base 2 to rotate on the workbench 1. Multiple sets of support rollers 3 are arranged circumferentially on the base 2, with two support rollers in each set, and the apples are fixed by clamping. The workbench 1 is provided with a second driving member that drives each set of support rollers 3 to rotate. Under the drive of the second driving member, each set of support rollers 3 has two movement modes: a first movement mode in which each set of support rollers 3 rotates in the same direction, using friction to turn the apples in the opposite direction; and a second movement mode in which each set of support rollers 3 moves axially, using friction to rub and turn the apples. The cleaning assembly washes the apples after each turning.

[0032] Specifically, workbench 1 is connected to an immersion tank containing a 10% sodium hypochlorite solution to prepare a 0.02% disinfectant solution, and then connected to equipment for drying the washed apples, forming an apple processing line. The washing device scrubs the apples soaked in the disinfectant solution to remove impurities and pesticide residues from their surface. However, during the washing process, the apples are not fixed in place, making it difficult to accurately scrub every part. Furthermore, the apple stems and calyxes are concave, making them even more difficult to clean thoroughly. Therefore, it is difficult to clean the stems and calyxes completely. This cleaning method is clearly flawed for apples intended for immediate consumption on a space station.

[0033] Therefore, based on the above problems, in this embodiment, each apple is washed in sections. When all sections are washed, the cleaning effect of the apples can be effectively improved. Since the placement of each apple is random during washing, for ease of understanding, we use a first straight line and a second straight line that are perpendicular to each other and pass through their respective center points as the central axes. Using the first straight line as the central axis, the circumference is divided into three equal sections, named the first, second, and third sections. Using the second straight line as the central axis, the circumference is divided into three equal sections, named the fourth, fifth, and sixth sections. The area where the apple initially corresponds to the washing component is designated as the first section. Therefore, one apple needs to be completely washed. When the first straight line is the central axis, it needs to be flipped twice. When the second straight line is the central axis, it also needs to be flipped twice. Because the number of areas allocated with different central axes is odd, the positions of the first and second straight lines change continuously. When the central axis switches from the first straight line to the second straight line, the apple needs to be rubbed once, with the second straight line as the central axis, and then flipped once, with the first straight line as the central axis. Correspondingly, the number of multiple sets of support rollers 3 on the flipping component is set to eight sets. The base 2 is divided into a feeding area 20 for apples to be washed, a flipping area 21 for apples to be washed, and a discharging area 22 for apples after washing (the feeding area 20, the flipping area 21, and the discharging area 22 are divided by dotted lines, as shown). Figure 2 As shown in the diagram, the first driving component drives the seat 2 to rotate intermittently. During the rotation, each set of support rollers 3 in the feeding area 20 clamps the apple as it enters the turning area 21. That is, the distance between each set of support rollers 3 can be elastically adjusted. Then, the apple is pressed between the two support rollers 3 in each set by external force. During the movement of each set of support rollers 3 in the turning area 21, the second driving component drives each set of support rollers 3 to move, so as to turn the apple. During the process of each set of support rollers 3 in the turning area 21 entering the unloading area 22, the apple can be removed from between the two support rollers 3 in each set by external force. In this way, during the intermittent rotation of the seat 2, the feeding of apples to be washed, the turning of apples to be washed, and the unloading of apples after washing can be completed. The first driving component can be a grooved wheel mechanism. The second driving component drives the support rollers 3 to rotate and move axially. For example, a combination of motor and cylinder can be used. These are existing technologies and will not be described in detail.

[0034] The beneficial effect of this embodiment is that by setting up a flipping component, the apple can be flipped at different angles during the apple washing process, so that every part of the apple can be cleaned by the washing component, thus improving the cleaning effect of the apple more effectively.

[0035] Preferably, the surface of the support roller 3 is covered with a rubber sleeve. Based on the elastic deformation of the rubber sleeve, the two support rollers 3 in each group clamp the apple to be washed. Specifically, the rubber sleeve can undergo elastic deformation after being squeezed by external force, and a good frictional effect can be formed between the rubber sleeve and the apple peel. In this way, when the apple is pressed between the two support rollers 3 in each group by external force, the rebound force of the two rubber sleeves can be used to clamp the apple. During the rotation of the two support rollers 3 in the same direction, one support roller 3 applies a downward squeezing force to the apple, and the other support roller 3 applies an upward squeezing force to the apple. In this way, the apple can rotate relative to the support rollers 3 while its position remains basically unchanged, thereby realizing the turning of the apple. When the second driving member drives one of the support rollers 3 in each group to move axially, it can apply an axial thrust to the apple, causing the apple to be rubbed.

[0036] Preferably, the first driving component includes a driving source mounted on the workbench 1 and an intermittent transmission mechanism. The power output end of the intermittent transmission mechanism is provided with a turntable 4. The edge of the turntable 4 is provided with a plurality of levers 5 along its circumferential direction. The support roller 3 is slidably arranged on the seat 2 along its own axial direction, and a first elastic element 6 is provided between the support roller 3 and the seat 2 in the sliding direction. During the forward rotation stroke of the turntable 4 driving the plurality of levers 5, the seat 2 moves circumferentially, and each set of support rollers 3 drives the apples to turn based on the driving action of the second driving component. During the reverse rotation stroke of the turntable 4 driving the plurality of levers 5, the plurality of levers 5 intermittently move each support roller 3 axially.

[0037] Specifically, the drive source drives the turntable 4 to move circumferentially through an intermittent transmission mechanism. The drive source can be a motor, and the intermittent transmission mechanism is a Geneva mechanism. The turntable 4 is fixed to the power output shaft of the Geneva mechanism. The rotation of the turntable 4 can drive multiple levers 5 arranged circumferentially to rotate together. When it is necessary to drive each group of support rollers 3 to move intermittently into different areas, the turntable 4 is driven to rotate in the forward direction (e.g., clockwise). At this time, the levers 5 will drive the support rollers 3 in the nearby positions to move together. When the turntable 4 is driven to rotate in the reverse direction (e.g., counterclockwise), the levers 5 will move together. 5. Following the reverse movement of the turntable 4, the end of the support roller 3 will be squeezed. The squeezed support roller 3 will move along its own axis. Thus, after each apple is turned, the turntable 4 is driven to rotate in the opposite direction, causing multiple levers 5 to sequentially move each support roller 3 along its own axis. Then, under the rebound force of the first elastic element 6, it will reset. In this way, the two support rollers 3 in each group will rub the apple, so that the apple and the cleaning component will form a circumferential relative movement, thereby effectively improving the cleaning effect, especially the cleaning effect on the stem cavity and calyx cavity of the apple.

[0038] In the circumferential direction, one side of the lever 5 is a plane 50 and the other side is a wedge-shaped surface 51. When the lever 5 rotates in the forward direction, the plane 50 abuts against the support roller 3, and the support roller 3 is pushed by the plane 50 to rotate. When it rotates in the reverse direction, the wedge-shaped surface 51 and the end of the support roller 3 form a wedge-shaped fit, so that the support roller 3 is subjected to axial compression.

[0039] Preferably, each set of support rollers 3 is provided with two baffles 7, and the support rollers 3 and the baffles 7 are in movable contact. The part between the two baffles 7 is used to place apples, and each baffle 7 is fixedly connected to the base 2. Specifically, in the aforementioned embodiment, when the turntable 4 drives multiple levers 5 to rotate in the opposite direction, the levers 5 will squeeze each support roller 3 to move axially. There is a gap between the two ends of the support roller 3 and the base 2. The baffles 7 can prevent the apples from entering the gap and being squeezed and damaged.

[0040] Preferably, the cleaning assembly includes a cover plate 8 fixed to the workbench 1, and a plurality of transmission plates 9 are arranged circumferentially on the cover plate 8. Each transmission plate 9 is slidably arranged on the cover plate 8 along the axial direction of the turntable 4. Each transmission plate 9 is provided with a brush 10 corresponding to the position when the second drive member drives each set of support rollers 3 to move. The transmission plate 9 drives the turntable 4 to rotate in the opposite direction based on the force of the intermittent transmission mechanism to drive the brush 10 to contact the apple.

[0041] Specifically, in the aforementioned embodiments, the cleaning component can be active. In this embodiment, a passive type is provided, wherein a circular plate 11 is movably provided on the power output shaft of the Geneva mechanism, and is fixedly connected to each transmission plate 9. A second elastic element 12 is provided between the circular plate 11 and the cover plate 8. A threaded section 13 is provided on the power output shaft of the Geneva mechanism, and the second elastic element 12 is sleeved on the threaded section 13. The circular plate 11 and the threaded section 13 can be screwed together. When the apple is not being cleaned, the elastic force of the second elastic element 12 makes the circular plate 11 tend to be screwed together with the threaded section 13. When the turntable 4 is driven to rotate in the opposite direction, the rotation of the power output shaft of the Geneva mechanism forms a relative rotation with the circular plate 11. Under the elastic force of the second elastic element 12, the circular plate 11 is screwed together with the threaded section 13. Based on the threaded action, the circular plate 11 will drive the transmission plate 9 to move towards the apple, so that the brush 10 contacts the apple. In this direction of movement, the circular plate When plate 11 disengages from threaded section 13, the elastic force of the second elastic element 12 causes plate 11 to move in the opposite direction and reconnect with threaded section 13. Thus, during the forward rotation of turntable 4, the power output shaft of the Geneva mechanism rotates in the forward direction, and under the action of the elastic force of the second elastic element 12, threaded section 13 connects with plate 11. Under the action of the thread, plate 11 moves away from apple and returns to its initial position (the position when the apple is not being cleaned). At this time, brush 10 and apple will also move away from each other. Thus, the forward rotation of Geneva mechanism can drive each set of support rollers 3 into different areas, and the reverse rotation of Geneva mechanism can drive support rollers 3 to move axially and drive brush 10 to contact apple. The axial movement of support rollers 3 rubs the apple, so that the apple and brush 10 form a rotating brushing action. The brush 10 is equipped with a nozzle, and the nozzle is connected to a water pipe. During the brush 10 brushing the apple, the nozzle sprays cleaning liquid onto the apple.

[0042] Preferably, the second driving component includes a gear 14 disposed at the end of each support roller 3 and multiple sets of first racks 15 arranged circumferentially on the worktable 1. Each set of first racks 15 consists of two racks, and the distance between each set of first racks 15 is equal to the distance between each set of support rollers 3 in the circumferential direction. The two gears 14 on each set of support rollers 3 are radially offset from each other on the turntable 4. During the forward rotation stroke of the seat 2, the gears 14 mesh with the first racks 15, and each set of support rollers 3 rotates in the same direction. The rotation causes the apple to flip in the opposite direction; it also includes a squeezing block 16, which is located on the middle set of first racks 15 among multiple sets of first racks 15. When each set of support rollers 3 and the squeezing block 16 form a mutual squeezing action, one of the support rollers 3 in each set moves axially to rub and flip the apple; each set of support rollers 3, in the stroke of the middle set of first racks 15 among multiple sets of first racks 15, first rubs and flips the apple, and then drives the apple to flip in the opposite direction.

[0043] Specifically, within the turning area 21, a set of first racks 15 is positioned between two adjacent brushes 10. When each set of support rollers 3 passes this position, the gear 14 on each support roller 3 meshes with the corresponding first rack 15. The gear 14 drives the connected support roller 3 to rotate, thus turning the apples. The distance between the two first racks 15 in each set is equal to the distance between each set of support rollers 3, ensuring that the two gears 14 corresponding to the two support rollers 3 in each set can simultaneously mesh with the corresponding first rack 15, allowing the two support rollers 3 to rotate simultaneously in the same direction, ensuring the normal turning of the packaged apples. As described in the foregoing embodiment, for Each apple is divided into six areas. In one step, the apple needs to be rubbed and then rolled in the opposite direction. Therefore, in this embodiment, a squeezing block 16 is set on the middle group of first racks 15. The squeezing block 16 and the support roller 3 form a squeezing action through a wedge engagement. When each group of support rollers 3 passes through this area, one of the support rollers 3 contacts the squeezing block 16, and the squeezing block 16 contacts the support roller 3 first, causing the support roller 3 to move axially to rub the apple. Then, the corresponding gear 14 meshes with the first rack 15, causing the apple to rotate in the opposite direction. In this way, the six areas of the apple can be washed separately.

[0044] In a further embodiment, the seat 2 is divided into a feeding area 20, a turning area 21, and a discharging area 22. During the turning process, the apple is constantly held by the two support rollers 3 of each group. Therefore, to facilitate automatic clamping and automatic removal of the clamps, in this embodiment, the two transmission plates 9 corresponding to the feeding area 20 and the discharging area 22 are each provided with openings for picking up and placing apples. Each transmission plate 9 has two second racks 17 near the end of the gear 14. The two second racks 17 correspond to the two gears 14 of each group of support rollers 3. That is, during the movement of each transmission plate 9 in the direction close to the apple, the two second racks 17 mesh with the corresponding gears 14, driving the gears 14 to rotate. This causes the two support rollers 3 of each group to rotate in opposite directions. The rotation of the two support rollers 3 causes the clamped apple to move upwards and closer to the brush 10. To achieve automatic clamping of the apple, when the brush 10 is brushing the apple, the apple is placed... Placed on a set of support rollers 3 in the feeding area 20, after the apples in the turning area 21 have finished one brushing, that is, as the brush 10 moves away from the apples, the set of support rollers 3 in the feeding area 20 rotates relative to each other under the action of two second racks 17 and two gears 14, so that the apples are pulled into the two sets of support rollers 3 and clamped. The distance that the two second racks 17 corresponding to the brush 10 move down should be less than the distance that the two second racks 17 in the feeding area 20 move down. In this way, as the brush 10 moves in the direction closer to the apples, the apples between each set of support rollers 3 in this area are pulled up but will not be separated from the clamping of the two support rollers 3. Correspondingly, the distance that the two second racks 17 in the unloading area 22 move down should be the same as the distance that the two second racks 17 in the feeding area 20 move down. In this way, when the set of support rollers 3 in the unloading area 22 rotates relative to each other, the clamping of the apples can be completely removed and the apples can be pushed upwards.

[0045] Another embodiment of the present invention also relates to a process for producing and processing ready-to-eat fresh apples for a space station. The method for processing apples using the aforementioned ready-to-eat fresh apple production and processing device for a space station includes the following steps:

[0046] Step 1, feeding: During the forward rotation of the seat 2 driven by the first drive component, the apples to be cleaned are sequentially fed into each set of conveyor rollers.

[0047] Step 2: Cleaning. The flipping component flips the apple multiple times at different angles. After each flip, the cleaning component cleans the apple.

[0048] Step 3, unloading: During the forward rotation of the seat 2 driven by the first drive component, the cleaned apples are removed from each set of conveyor rollers in sequence.

[0049] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
