Description

Technical Field

[0001] This invention belongs to the field of fruit drying technology, and specifically relates to an intelligent fruit drying device. Background Technology

[0002] Persimmon cakes are a traditional specialty fruit product of the Lingnan region. Made from persimmons through processes such as peeling, drying, shaping, and frosting. The flesh is soft and glutinous, covered with a white sugar frost, sweet but not cloying, and rich in nutrients. They are believed to have benefits such as moisturizing the lungs and relieving coughs, as well as strengthening the spleen and stomach. The mild climate of Lingnan is ideal for persimmon growth, resulting in high-quality persimmon cakes with a long history of cultivation. They are widely loved and are a seasonal delicacy and a popular gift in the autumn and winter seasons.

[0003] As the popularity of dried persimmons continues to rise, market demand is increasing daily. To adapt to this trend, the production of dried persimmons is transitioning from manual labor to automated machinery. Existing machines include a drying room, and hot air and extrusion devices arranged from top to bottom within the drying room. The hot air device dries the persimmons by delivering hot air to them, while the extrusion device squeezes and kneads the persimmons during the drying process.

[0004] Since the hot air device dries persimmons by conveying hot air, the temperature of the hot air is easily affected by the conveying distance. When the hot air reaches the top of the persimmon, its heat is absorbed by the top. By the time it reaches the bottom of the persimmon, the heat of the hot air is significantly insufficient, resulting in uneven heating of the persimmon from top to bottom. This leads to poor drying effect and low efficiency of the hot air device. Summary of the Invention

[0005] To address the problems of poor drying effect and low efficiency of traditional hot air devices for persimmons, this invention provides an intelligent fruit drying device.

[0006] The objective of this invention can be achieved through the following technical solutions: A smart drying device for dried fruit includes a hollow drying production chamber, drying equipment, and a workbench. The drying equipment is located at the top of the drying production chamber and is used to provide a rated temperature for the drying production chamber. The workbench is located inside the drying production chamber and is directly below the drying equipment. The workbench surface is made of heat-absorbing material, and the inner wall of the drying production chamber is lined with heat-insulating panels.

[0007] As a preferred embodiment of the present invention, it further includes a plurality of placement trays. The workbench has a plurality of working slots. The plurality of working slots are equally spaced along the axial direction of the workbench. The plurality of placement trays correspond to and match the plurality of working slots. Any of the placement trays is placed in the corresponding working slot. The surface of the placement tray is flush with the table surface of the workbench. The placement tray is used to hold persimmons.

[0008] As a preferred technical solution of the present invention, it further includes a plurality of heat-insulating components, which are matched with a plurality of placement trays, and any one of the heat-insulating components is disposed around the corresponding placement tray. The heat preservation component includes several heat preservation blocks, which are arranged at equal angles around the central axis of the placement tray. The end face of the heat preservation block near the persimmon is arc-shaped. The heat preservation block is made of heat-absorbing material and is fitted to the surface of the workbench.

[0009] As a preferred embodiment of the present invention, the bottom end of the arc-shaped surface of the insulation block is tangent to the tabletop of the workbench.

[0010] As a preferred embodiment of the present invention, the heat preservation component further includes a plurality of hydraulic cylinders, which are matched with a plurality of heat preservation blocks. The output end of any hydraulic cylinder is connected to the corresponding heat preservation block, and the extension and retraction direction of the hydraulic cylinder intersects the central axis of the corresponding placement plate at the same point.

[0011] As a preferred embodiment of the present invention, it further includes a plurality of extrusion devices, which are matched with a plurality of placement trays, and any one of the extrusion devices is disposed directly above the corresponding placement tray. The extrusion device includes an extrusion cylinder, an extrusion rod, and an extrusion block. The extrusion cylinder is suspended directly above the worktable. The two ends of the extrusion rod are coaxially connected to the extrusion block and the output end of the extrusion cylinder, respectively. The central axis of the extrusion block coincides with the central axis of the placement tray.

[0012] In a preferred embodiment of the present invention, the diameter of the extrusion block is larger than the diameter of the extrusion rod, and the diameter of the extrusion block is smaller than the maximum diameter of the outer ring of the persimmon.

[0013] As a preferred embodiment of the present invention, the placement disk is rotatably disposed in a corresponding working slot, and the invention further includes a plurality of rotating motors, which are matched with a plurality of placement disks. Each of the rotating motors is disposed in a corresponding working slot, and the output end of the rotating motor is coaxially connected to the placement disk.

[0014] As a preferred embodiment of the present invention, the extrusion device further includes a telescopic cylinder and a telescopic block. The extrusion block is coaxially provided with a telescopic groove. The telescopic cylinder is disposed in the telescopic groove. The telescopic block is slidably disposed in the telescopic groove. The telescopic block is coaxially connected to the output end of the telescopic cylinder. The surface of the telescopic block can be locked or released from its flush fit with the surface of the extrusion block.

[0015] As a preferred embodiment of the present invention, the diameter of the telescopic block is smaller than the inner diameter of the recess at the top of the persimmon.

[0016] The beneficial effects of this invention are as follows: By setting up a sealed, insulated environment in the drying production chamber and installing drying equipment, the drying equipment applies a rated temperature to the drying production chamber, causing the temperature inside to continuously rise and eventually maintain a preset temperature. Once the drying production chamber reaches the rated constant temperature environment, the persimmons are sent to the workbench for drying, ensuring that the persimmons are heated evenly to guarantee a good drying effect. In addition, the workbench surface in this solution is made of heat-absorbing material, which allows the workbench to absorb heat from the drying production chamber. The drying equipment first dries the drying production chamber... During the heating process, the workbench surface also absorbs heat from the drying production room, ultimately achieving a rated constant temperature environment in both the drying production room and the workbench. Placing the persimmons on the workbench at this time ensures that the persimmons are heated evenly all over. Furthermore, during the subsequent drying process, the heat lost from the bottom of the persimmons can be quickly replenished through the workbench surface, ensuring that the heat lost from the periphery of the persimmons is replenished in a timely manner. This achieves a uniform drying effect from top to bottom, solving the drawbacks of traditional machines that use hot air devices to dry persimmons. Attached Figure Description

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0021] Please see Figures 1-5This embodiment provides an intelligent fruit drying device, including a hollow drying production chamber 1, a drying equipment 2, and a workbench 3. The drying equipment 2 is located at the top of the drying production chamber 1 to provide a rated temperature. The workbench 3 is located inside the drying production chamber 1, directly below the drying equipment 2. The workbench 3's surface is made of heat-absorbing material, and the inner wall of the drying production chamber 1 is lined with insulation boards. By setting the drying production chamber 1 as a sealed, insulated environment and installing the drying equipment 2, the drying equipment 2 applies a rated temperature to the drying production chamber 1, causing the temperature inside the drying production chamber 1 to continuously rise and eventually maintain a preset temperature. After the drying production chamber 1 reaches the rated constant temperature environment, persimmons are placed on the workbench 3 for drying, ensuring that the persimmons are heated evenly throughout. To ensure a good drying effect, it is worth noting that the above design can only solve the problem of the persimmons being in a uniformly heated environment when they are first being dried. During the continuous drying process, the persimmons will absorb a large amount of heat from the drying production room 1. In order to ensure the subsequent drying effect of the persimmons, the drying equipment 2 needs to replenish the heat in the drying production room 1 in a timely manner. However, since the drying equipment 2 is set on top of the workbench 3, the distance between the space at the top of the persimmons and the drying equipment 2 in the drying production room 1 is shorter than the distance between the space at the bottom of the persimmons and the drying equipment 2. As a result, the heat lost in the space at the bottom of the persimmons cannot be replenished in time during the continuous drying process, which ultimately leads to the problem of uneven heating of the persimmons during the continuous drying process. To address this issue, the workbench 3 in this solution is made of a heat-absorbing material, enabling it to absorb heat from the drying production room 1. As described in the above embodiment, the drying equipment 2 first heats the drying production room 1, during which the workbench 3 also absorbs heat from the drying production room 1, ultimately achieving a rated constant temperature environment for both the drying production room 1 and the workbench 3. Placing the persimmons on the workbench 3 at this point ensures even heating of the persimmons. Furthermore, during subsequent drying, heat lost from the bottom of the persimmons can be quickly replenished through the workbench 3, ensuring timely replenishment of heat lost from the periphery and achieving a uniform drying effect. This solves the problem of uneven heating of the persimmons caused by the temperature of the hot air supplied by the hot air device being easily affected by distance variations when using a traditional machine for drying persimmons, resulting in poor drying effect and low efficiency.

[0022] Specifically, this solution also includes several placement trays 4, and the workbench 3 has several working slots 301. The several working slots 301 are equally spaced along the axial direction of the workbench 3. The several placement trays 4 are matched with the several working slots 301. Any placement tray 4 is placed in the corresponding working slot 301. The surface of the placement tray 4 is flush with the table surface of the workbench 3. The placement tray 4 is used to hold persimmons.

[0023] During the continuous drying process of persimmons, in order to further improve the heat transfer from the workbench 3 to the bottom of the persimmons, this solution also includes a heat preservation component 5. Several heat preservation components 5 are matched with several placement trays 4, and each heat preservation component 5 is set around the corresponding placement tray 4. The heat preservation component 5 includes several heat preservation blocks 501, which are set at equal angles around the central axis of the placement tray 4. The end face of the heat preservation block 501 near the persimmon is set with an arc shape. The heat preservation block 501 is made of heat-absorbing material and is set in close contact with the workbench 3. By setting the heat preservation block 501, since the distance between the heat preservation block 501 and the bottom of the persimmon is shorter than the distance between the workbench 3 and the bottom of the persimmon, the heat from the workbench 3 can be directly transferred to the bottom of the persimmon through the heat preservation block 501, further improving the speed and efficiency of heat transfer from the workbench 3 to the bottom of the persimmon. It is worth noting that, in order to reduce the distance between the bottom of the persimmon and the insulation block 501, since the bottom of the persimmon has an arc-shaped structure, the end face of the insulation block 501 near the persimmon is set in an arc shape, and the bottom end of the arc-shaped surface of the insulation block 501 is tangent to the tabletop of the workbench 3.

[0024] Furthermore, in order to accommodate persimmons of different sizes, the insulation component 5 of this solution also includes several hydraulic cylinders 502, which are matched with several insulation blocks 501. The output end of any hydraulic cylinder 502 is connected to the corresponding insulation block 501, and the extension and retraction direction of the hydraulic cylinder 502 intersects the central axis of the corresponding placement plate 4 at the same point. By setting up the hydraulic cylinders 502, the hydraulic cylinders 502 control the movement of the insulation blocks 501, changing the distance between two relative insulation blocks 501, thereby accommodating persimmons of different sizes.

[0025] During the drying process of persimmons, they also need to be squeezed to promote dehydration. Therefore, this solution includes several squeezing devices 6, each corresponding to a set of trays 4. Each squeezing device 6 is positioned directly above its corresponding tray 4. Each squeezing device 6 includes a squeezing cylinder 601, a squeezing rod 602, and a squeezing block 603. The squeezing cylinder 601 is suspended directly above the worktable 3. The two ends of the squeezing rod 602 are coaxially connected to the output ends of the squeezing block 603 and the squeezing cylinder 601, respectively. The central axis of the squeezing block 603 coincides with the central axis of the set-top tray 4. With the squeezing devices 6, when the squeezing cylinder 601 starts working, it controls the squeezing block 603 to move towards the top of the persimmon, thus squeezing the persimmon. It is worth noting that in this solution, the diameter of the squeezing block 603 is larger than the diameter of the squeezing rod 602, but smaller than the maximum diameter of the outer ring of the persimmon.

[0026] Furthermore, during the drying process of persimmons, internal moisture loss occurs. Since this moisture loss is random, the berries inside the persimmon are unevenly distributed. When the extrusion block 603 extrudes the persimmon, some of the berries concentrate and shift to one side of the persimmon. Visually, after being extruded by the extrusion block 603, one side of the persimmon noticeably expands, unlike the even expansion of a finished persimmon cake. To address this issue, it's easy to imagine controlling the movement of the insulation block 501 to achieve a curved surface fit between the persimmon and the insulation block 501, thus limiting further expansion of the swollen end of the persimmon. However, since the expansion direction of persimmons is random during the extrusion process, and there is a gap between adjacent insulation blocks 501, the expansion end of the persimmon may occur within the gap between the two insulation blocks 501. This prevents the expansion end of the persimmon from being restricted by contact with the arc-shaped surface of the insulation block 501. To address this issue, the placement disk 4 is rotatably disposed within the corresponding working slot 301. The solution also includes several rotating motors 7, which are matched with several placement disks 4. Each rotating motor 7 is disposed within the corresponding working slot 301, and the output end of the rotating motor 7 is coaxially connected to the placement disk 4. By providing the rotating motors 7, the placement disk 4 can be rotated, thereby causing the persimmon to rotate and its expansion end to rotate onto the arc-shaped surface of the insulation block 501.

[0027] Furthermore, to limit the persimmon's rotation around the central axis of the placement tray 4 during rotation, this solution requires pressing the central axis of the persimmon when rotating the placement tray 4. A straightforward approach would be to press the center of the top of the persimmon using the squeezing block 603. However, due to the large bottom area of ​​the squeezing block 603, pressing the persimmon with it can easily cause the placement tray 4 to rotate while the persimmon remains stationary. Therefore, to address this issue, the squeezing device 6 also includes a telescopic cylinder 604 and a telescopic block 605. The bottom end of the squeezing block 603 has a coaxial telescopic slot, the telescopic cylinder 604 is positioned within the telescopic slot, and the telescopic block 605 can slide... The telescopic block 605 is dynamically installed inside the telescopic slot and is coaxially connected to the output end of the telescopic cylinder 604. The surface of the telescopic block 605 can be locked or released from its flush fit with the surface of the pressing block 603. With the telescopic cylinder 604 installed, under normal conditions, the surface of the telescopic block 605 and the surface of the pressing block 603 maintain a flush fit. When the telescopic block 605 needs to be pressed on the central axis of the persimmon, the telescopic cylinder 604 controls the telescopic block 605 to extend out of the pressing block 603, thereby realizing that the telescopic block 605 is pressed on the central axis of the top of the persimmon. It should be noted that in order to reduce the contact area between the telescopic block 605 and the persimmon, the diameter of the telescopic block 605 is smaller than the inner diameter of the recess at the top of the persimmon.

[0028] Furthermore, the swollen end of the persimmon may also appear between the gap space and one end of the adjacent insulation block 501. In this case, the swollen end of the persimmon is likely to come into contact with the corner of one end of the insulation block 501. Since the persimmon is soft at this time, the skin at the point where the swollen end of the persimmon contacts the corner of one end of the insulation block 501 is prone to cracking. If the cracked skin is left unattended, the larger the gap of the cracked skin at the swollen end of the persimmon will be when the persimmon is squeezed later, the more likely the berry inside the persimmon may flow out along the crack. It is worth noting that... Since the persimmon is soft at this time, the cracked areas on its surface can be repaired by pressing the persimmon skin in the direction where the cracking tendency decreases. To achieve this effect, the solution also includes several pressing units 8, which are matched with several heat-insulating blocks 501. Each pressing unit 8 is located within a corresponding heat-insulating block 501. Specifically, along the rotation direction of the placement plate 4, a pressing groove is formed at the end of the heat-insulating block 501 that contacts the persimmon. The pressing groove is connected to the arc-shaped surface of the heat-insulating block 501. 8 is set in the pressing slot; the pressing unit 8 includes a pressing cylinder 801 and a pressing block 802. The pressing cylinder 801 is set in the pressing slot, and the pressing block 802 is slidably set in the pressing slot. The output end of the pressing cylinder 801 is connected to the pressing block 802. The surface of the pressing block 802 can be locked or released to form an arc surface with the end face of the insulation block 501. The surface of the pressing block 802 is an arc surface, and its curvature is consistent with the curvature of the arc surface of the insulation block 501. Under normal conditions, the pressing block 802 and the insulation block 501 together form an arc surface. When the persimmon After the skin at the swollen end of the persimmon cracks, the control plate 4 rotates, causing the cracked position at the swollen end of the persimmon to rotate to the front of the moving path of the pressing block 802. At this time, it is necessary to control that all cracked positions of the persimmon are located on the same side of the moving path of the pressing block 802. Then, the pressing block 802 is extended, pressing the cracked position of the persimmon and driving one side of the cracked opening of the persimmon to move to the other side, narrowing the opening of the cracked position of the persimmon. After a period of time, the cracked position of the persimmon skin can be re-solidified. Finally, the pressing block 802 is driven to complete the reset. It should be noted that since the function of the insulation block 501 is to limit the expansion of the persimmon's bulging end, in the actual design process, the arc length of a single insulation block 501 will be 1 / 5 to 1 / 6 of the persimmon's total arc length. Therefore, the arc length of a single insulation block 501 will be much larger than the persimmon's crack opening. In addition, the surface curvature of persimmons is not uniform. Therefore, in reality, the curvature of the insulation block 501 when viewed from above is greater than the surface curvature of the persimmon to adapt to the persimmon's uneven surface curvature. Therefore, in practice, it is difficult to press the cracked part of the persimmon using the insulation block 501.
