Among them, the common methods for dehydrating vegetables include manual extrusion, natural drying, or manual centrifuging, etc. However, in factories, the amount of vegetables to be dehydrated is large and the dehydration requirements are high, and these dehydration methods for vegetables are difficult to meet the requirements.

[0003] In view of the above problems, the Chinese utility model patent with the authorized patent announcement number CN205884638U discloses a vegetable rapid centrifugal dryer, which includes an outer box body and a rotating barrel arranged inside the outer box body.

[0004] The above-mentioned prior art solutions have the following defects: When the vegetables are centrifuged dry, it is necessary to manually reach into the rotating barrel to take out the centrifuged dry vegetables inside the rotating barrel. When the rotating barrel is relatively deep, it is difficult to take out the materials from the centrifugal dryer. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, one of the purposes of the present invention is to provide a new type of continuous vegetable centrifugal dryer to solve the problem of difficult material taking of the existing centrifugal dryer.

[0006] The above-mentioned invention purpose of the present invention is achieved through the following technical solutions:

[0007] A new type of continuous vegetable centrifugal dryer includes a centrifuging mechanism, a scraping mechanism arranged inside the centrifuging mechanism, and a conveying mechanism arranged below the centrifuging mechanism for receiving and conveying the centrifuged dry vegetables; among them, the centrifuging mechanism includes a support frame, a housing installed on the support frame and having open ends at both ends, an inner cylinder rotatably installed inside the housing and having open ends at both ends, a receiving plate arranged inside the inner cylinder to receive vegetables, and a driving structure for driving the inner cylinder and the receiving plate to rotate; in addition, filter holes are provided on the side wall of the inner cylinder.

[0008] By adopting the above technical solution, the driving structure is started to rotate the material receiving plate, and then vegetables are placed on the material receiving plate. The vegetables on the material receiving plate are thrown to the side wall of the inner cylinder under the action of the centrifugal force of the material receiving plate and rotate together with the inner cylinder. The water on the vegetables flies out from the filter holes, thereby realizing the dehydration of the vegetables. In addition, since the lower ends of both the inner cylinder and the outer shell are open, when the vegetables are dried, the scraping mechanism is started to make the vegetables fall from the bottom of the inner cylinder onto the conveying mechanism, eliminating the need for manual removal of the dried vegetables from the bottom of the inner cylinder and solving the problem of difficult material taking of the existing drying machine.

[0009] In a preferred example of the present invention, it can be further configured that the drying machine further includes a feeding mechanism, and the discharging end of the feeding mechanism is located above the inner cylinder.

[0011] In a preferred example of the present invention, it can be further configured that a guiding hopper is provided at the discharging end of the feeding mechanism, and the side of the guiding hopper away from the feeding mechanism is located directly above the material receiving plate.

[0012] By adopting the above technical solution, the vegetables conveyed by the feeding mechanism fall onto the material receiving plate through the guiding hopper, reducing the possibility of the vegetables falling into the gap between the outer shell and the inner cylinder.

[0014] By adopting the above technical solution, when the vegetables reach the drying time, the driving member is started to drive the scraping plate to move towards the side close to the side wall of the inner cylinder, making the scraping plate close to the side wall of the inner cylinder. The dried vegetables hit the scraping plate, and under the action of the gravity of the vegetables themselves, the vegetables fall from the open end at the lower end of the inner cylinder onto the conveying mechanism.

[0015] In a preferred example of the present invention, it can be further configured that a jetting mechanism is provided on the inner side wall of the outer shell; the jetting mechanism includes jetting heads, and multiple groups of jetting heads are arranged in parallel around the inner side wall of the outer shell, and multiple jetting heads are evenly distributed along the height direction of the outer shell in each group.

[0016] By adopting the above technical solution, the jet head is installed on the inner wall of the housing, and the jet head faces the side of the inner cylinder. When feeding materials, the jet head is started to jet air into the inner cylinder, and the air flow enters the inner cylinder through the filter holes, which can help the vegetables after dehydration to fall onto the conveying mechanism.

[0017] In a preferred example of the present invention, it can be further configured that: the driving structure includes a mounting bracket installed on the housing, a rotating motor installed on the mounting bracket, a rotating shaft connected to the rotating motor and located at the center of the inner cylinder, a bearing connected to the end of the rotating shaft away from the rotating motor, and a connecting frame provided on the outer peripheral side of the bearing; wherein, the connecting frame is fixedly connected to the inner cylinder.

[0018] By adopting the above technical solution, when the rotating motor is started, the rotating motor drives the connecting frame connected to the bearing through the rotating shaft, and the connecting frame is fixedly connected to the inner cylinder, so that the inner cylinder rotates along its circumferential direction to dehydrate the vegetables in the inner cylinder.

[0019] In a preferred example of the present invention, it can be further configured that: the dehydrator further includes a cleaning mechanism; the cleaning mechanism includes a spray head for cleaning the inner cylinder and the inner side wall of the housing, a water inlet assembly for supplying water to the spray head, and a water outlet assembly provided at the bottom of the housing for discharging sewage.

[0020] By adopting the above technical solution, the cleaning mechanism includes a water inlet assembly, and the water inlet assembly supplies water to the spray head, so that the spray head sprays water to clean the housing and the inner side wall of the inner cylinder, thereby removing the vegetables remaining on the inner cylinder or the inner wall of the housing and reducing the problem that the dehydrator emits an odor due to the vegetables remaining on the inner wall of the inner cylinder or the housing.

[0023] In a preferred example of the present invention, it can be further configured that: the water inlet assembly includes a water inlet pipe communicated with the rotating shaft and a connecting ring provided at one end of the water inlet pipe, wherein, a connecting head is provided at the end of the rotating shaft away from the rotating motor, an annular cavity is provided in the connecting head, the connecting ring is located in the annular cavity, and the connecting ring is rotatably connected to the annular cavity.

[0024] By adopting the above technical solution, when the rotating motor drives the rotating shaft to rotate, the rotating shaft drives the connecting head to rotate, and the connecting ring is rotatably connected to the connecting head, so that the connecting ring will not rotate with the connecting head, and further the water inlet pipe will not rotate with the rotating shaft.

[0025] In a preferred example, the present invention can be further configured as: a movable door is provided on the circumferential side of the outer shell, and the movable door is slidably or rotatably connected to the outer shell.

[0026] By adopting the above technical solution, a movable door is arranged on the circumferential side of the outer shell, and the movable door is slidably or rotatably connected to the outer shell, so that the movable door can be opened to check the cleaning condition of the inner wall of the outer shell and the inner cylinder. When it is not cleaned thoroughly, the cleaning mechanism can be started again to clean the outer shell and the inner cylinder.

[0027] In summary, the present invention includes at least one of the following beneficial technical effects:

[0028] 1. Start the driving structure to make the material receiving plate rotate, and then put the vegetables on the material receiving plate. The vegetables located on the material receiving plate are thrown to the side wall of the inner cylinder under the action of the centrifugal force of the material receiving plate and rotate with the inner cylinder together. The water on the vegetables flies out from the filter holes, so as to realize the dehydration of the vegetables; in addition, since both the lower ends of the inner cylinder and the outer shell are open, when the vegetables are dried, start the scraping mechanism to make the vegetables fall from the bottom of the inner cylinder onto the conveying mechanism, and there is no need to manually take out the dried vegetables from the bottom of the inner cylinder, solving the problem of difficult material taking of the existing drying machine;

Specific implementation mode

[0036] The present invention will be further described in detail below with reference to the accompanying drawings.

[0037] In this embodiment: Refer to Figure 1 , a new type of continuous vegetable dryer disclosed by the present invention includes a drying mechanism 2, a feeding mechanism 1, a scraping mechanism, and a conveying mechanism 4. Among them, the feeding mechanism 1 is located on one side of the drying mechanism 2 and extends to the top of the drying mechanism 2, and the feeding mechanism 1 is controlled by a PLC controller to achieve the purpose of automatic intermittent feeding; the scraping mechanism is located inside the drying mechanism 2, and the scraping mechanism is also controlled by a PLC controller, and the feeding is controlled regularly according to the preset drying time of the drying mechanism 2; and the feeding end of the conveying mechanism 4 is located below the drying mechanism 2, and can convey the dried vegetables to the next process. In this embodiment, the feeding mechanism 1 and the conveying mechanism 4 are specifically conveyor belts.

[0038] Refer to Figure 1 and Figure 2 , the drying mechanism 2 includes a support frame 21, an outer shell 22, an inner cylinder 23, and a driving structure for driving the inner cylinder 23 to rotate.

[0039] Refer to Figure 2 , multiple support frames 21 are provided. In this embodiment, three support frames 21 are taken as an example, and the three support frames 21 are evenly distributed around the outer periphery of the outer shell 22, and the support frames 21 are fixedly connected to the outer shell 22. Among them, the support frame 21 and the outer shell 22 can be integrally formed, or they can be two independent individuals. When the support frame 21 and the outer shell 22 are two independent individuals, the fixing method of the support frame 21 and the outer shell 22 can be adhesive fixing, welding fixing, etc.

[0040] The outer shell 22 is located outside the inner cylinder 23, the inner cylinder 23 is rotatably arranged inside the outer shell 22, and both ends of the outer cylinder are open. Among them, the cross-section of the outer shell 22 can be circular, polygonal, etc. In this embodiment, the cross-section of the outer shell 22 is taken as an example of a circle.

[0041] The inner cylinder 23 is arranged in a cylindrical shape, and both ends of the inner cylinder 23 are also open. Moreover, the size of the opening at the lower end of the outer shell 22 is equal to the size of the opening at the lower end of the inner cylinder 23. In addition, a number of tiny filter holes 231 are evenly distributed on the outer side wall of the inner cylinder 23. When the inner cylinder 23 rotates, the water on the vegetables enters the gap between the outer shell 22 and the inner cylinder 23 through the filter holes 231 under the action of centrifugal force. And a drain port is provided at the bottom of the gap between the outer shell 22 and the inner cylinder 23, so as to achieve the purpose of separating the vegetables from the water on the vegetables.

[0042] Referring to Figure 2 and Figure 3 , the driving structure includes a mounting frame, a rotating motor 26, a rotating shaft 27, a bearing and a connecting frame. Among them, the mounting frame includes three mounting rods 24 evenly distributed at the opening at the upper end of the outer shell 22. An installation plate 25 is connected between the three mounting rods 24, and the central axis of the installation plate 25 coincides with the central axis of the inner cylinder 23. The rotating motor 26 is installed on the side of the installation plate 25 facing away from the inner cylinder 23 by bolts, and the output shaft of the rotating motor 26 passes through the installation plate 25 and is fixedly connected to the rotating shaft 27. The central axis of the rotating shaft 27 coincides with the central axis of the inner cylinder 23. In this embodiment, to prevent water from entering the motor, a waterproof cover 261 is provided on the outer peripheral side of the rotating motor 26. The waterproof cover 261 is installed on the installation plate 25, and the waterproof cover 261 surrounds the rotating motor 26 inside the waterproof cover 261. The bearing is fixedly connected to the end of the rotating shaft 27 away from the motor. To prevent water from entering the bearing and affecting the service life of the bearing, in this embodiment, a bearing cover 28 is provided on the outer side of the bearing. The bearing cover 28 surrounds the bearing inside the bearing cover 28. The connecting frame is welded and fixed to the outer peripheral side of the bearing cover 28. The connecting frame includes a number of connecting rods 29 evenly distributed on the outer peripheral side of the bearing cover 28. In this embodiment, three connecting rods 29 are taken as an example. The ends of the three connecting rods 29 away from the bearing cover 28 are all welded and fixed to the inner side wall of the bottom of the inner cylinder 23.

[0043] Since the lower ends of the inner cylinder 23 and the outer cylinder are open, to prevent the problem that when the feeding mechanism 1 feeds, the vegetables to be dried directly fall from the opening at the lower end of the inner cylinder 23 onto the conveying mechanism 4, in this embodiment, a receiving plate 271 is fixedly provided on the outer peripheral side of the rotating shaft 27, and the receiving plate 271 is located inside the inner cylinder 23. Among them, the receiving plate 271 can be a flat plate with a circular or polygonal cross-section, or can be an arc-shaped plate. When the receiving plate 271 is an arc-shaped plate, the arc opening of the arc-shaped plate faces away from the rotating motor 26. In this embodiment, the receiving plate 271 is taken as a flat plate with a circular cross-section as an example. When the rotating motor 26 drives the rotating shaft 27 to rotate, the receiving plate 271 rotates with the rotating shaft 27. Under the action of centrifugal force, the vegetables falling onto the receiving plate 271 are thrown to the inner side wall of the inner cylinder 23 and rotate with the inner side wall of the inner cylinder 23, so as to achieve the purpose of dehydration.

[0044] In addition, since there is a gap between the outer shell 22 and the inner cylinder 23, in order to reduce the possibility of vegetables falling into the gap between the outer shell 22 and the inner cylinder 23 when the feeding mechanism 1 feeds materials, in this embodiment, a material guiding hopper 11 is provided on the side of the feeding mechanism 1 close to the drying mechanism 2. One side of the material guiding hopper 11 is fixed to the end of the feeding mechanism 1, and the other end is located directly above the receiving plate 271.

[0045] Referring to Figure 3 , the scraping mechanism includes a scraping air cylinder 31 installed on the mounting rod 24. The piston rod of the scraping air cylinder 31 is fixedly connected with a scraping plate 32, and the scraping plate 32 extends towards the inner cylinder 23 until it passes through the inner cylinder 23. Among them, the scraping air cylinder 31 is connected to the PLC controller, and the piston rod of the scraping air cylinder 31 drives the scraping plate 32 to move back and forth along the radial direction of the inner cylinder 23. In addition, in order to prevent the scraping air cylinder 31 from being affected by water ingress and affecting the work, in this example, a protective shell 311 is provided on the outer peripheral side of the scraping air cylinder 31. The protective shell 311 is installed on the mounting rod 24, and the protective shell 311 surrounds the scraping air cylinder 31 to reduce the possibility of water on the vegetables entering the scraping air cylinder 31.

[0046] When the drying mechanism 2 is working, the PLC controller starts the scraping air cylinder 31 to drive the scraping plate 32 to move towards the side close to the central axis of the inner cylinder 23, so that the scraping plate 32 is away from the vegetables being dried; and when the vegetables reach the drying time, the PLC controller starts the scraping air cylinder 31 to drive the scraping plate 32 to move towards the side close to the side wall of the inner cylinder 23, so that the scraping plate 32 is close to the side wall of the inner cylinder 23. Among them, in order to prevent the scraping plate 32 from affecting the rotation of the inner cylinder 23, there is usually a gap between the scraping plate 32 and the inner cylinder 23. In this embodiment, while not affecting the rotation of the inner cylinder 23, in order to ensure the blanking effect, the gap is between 1 and 3 mm. At this time, the dried vegetables hit the scraping plate 32, and under the action of the gravity of the vegetables themselves, the vegetables fall from the open end at the lower end of the inner cylinder 23 onto the conveying mechanism 4.

[0047] Referring to Figure 3, To improve the feeding efficiency of the scraping mechanism and make the vegetables attached to the inner wall of the inner cylinder 23 fall into the conveying mechanism 4 as much as possible, in this embodiment, a jetting mechanism is provided on the side wall of the outer shell 22. The jetting mechanism includes a jet head 5 and a jet switch (not shown in the figure). Among them, multiple groups of jet heads 5 are arranged at intervals around the inner side wall of the outer shell 22, and multiple jet heads 5 are evenly distributed along the height direction of the inner cylinder 23 in each group, so that the jet heads 5 jet air on the inner cylinder 23 in all directions, spraying the vegetables attached to the inner wall of the inner cylinder 23 as much as possible, and at the same time improving the feeding efficiency of the scraping mechanism through jetting. In addition, the jet switch is synchronously controlled by the PLC controller that controls the scraping cylinder 31. When feeding is required, the PLC controller starts the scraping cylinder 31 to make the scraping plate 32 approach the inner side wall of the inner cylinder 23. At the same time, the PLC controller controls the jet switch to open, so that the jet heads 5 jet air on the inner cylinder 23. After the feeding is completed, the PLC controller starts the scraping cylinder 31 to make the scraping plate 32 move away from the inner side wall of the inner cylinder 23. At the same time, the PLC controller controls the jet switch to close.

[0048] In addition, referring to Figure 2 and Figure 3 , after the drying mechanism 2 finishes working, the drying mechanism 2 needs to be cleaned, otherwise the drying mechanism 2 is prone to odor. In this embodiment, a cleaning mechanism is provided inside the drying mechanism 2. The cleaning mechanism includes a water inlet assembly, a spray head 61 and a water outlet assembly. Among them, the spray head 61 is preferably a high-pressure spray head. The spray head 61 can be installed on the inner side wall of the outer shell 22 or on the rotating shaft 27. When the spray head 61 is installed on the rotating shaft 27, the inside of the rotating shaft 27 is hollow. In this embodiment, the case where the spray head 61 is installed on the rotating shaft 27 is taken as an example.

[0049] Referring to Figure 2 and Figure 3 , the water inlet assembly includes a water inlet pipe 62 and a connecting ring 621. The connecting ring 621 is fixed to one end of the water inlet pipe 62 close to the rotating shaft 27, and the connecting ring 621 is welded or adhesively fixed to the outer peripheral side of the connecting rod 29. Among them, a connecting head 272 is provided at one end of the rotating shaft 27 away from the rotating motor 26. The cross section of the connecting head 272 is circular, and an annular cavity is provided around the circumference of the connecting head 272. The connecting ring 621 is rotatably arranged in the annular cavity.

[0050] The spray head 61 is fixedly installed on the outer peripheral side of the rotating shaft 27, and multiple groups of spray heads 61 are arranged along the length direction of the rotating shaft 27. Each group of spray heads includes three spray heads 61, and the three spray heads 61 are evenly distributed around the circumference of the air shaft. Water is supplied to the rotating shaft 27 through the water inlet pipe 62, and the spray head 61 cleans the inner side wall of the inner cylinder 23 and the inner side wall of the outer cylinder from the center of the inner cylinder 23 to the outside.

[0051] The water outlet assembly mainly includes a water outlet pipe 63, which is installed at the drainage opening between the outer shell 22 and the inner cylinder 23. The water outlet pipe 63 communicates with the gap between the outer shell 22 and the inner cylinder 23, and can drain the sewage between the outer shell 22 and the inner cylinder 23. At the same time, when cleaning the spin dryer, a water receiving bucket can also be placed on the conveying mechanism 4, with the water receiving bucket facing the inner cylinder 23 directly, and the inner diameter of the water receiving bucket being larger than that of the inner cylinder 23, so as to catch the sewage that may flow out of the inner cylinder 23 and prevent the sewage from directly falling on the conveying mechanism 4.

[0052] Referring to Figure 2 , for the convenience of checking the cleaning conditions of the inner cylinder 23 and the outer shell 22, in this embodiment, a movable door 7 is provided on the side wall of the outer shell 22. Among them, the movable door 7 can be a sliding door or a hinged door hinged with a hinge, etc. In this embodiment, the movable door 7 takes the hinged door hinged with a hinge as an example. Specifically, the cross-section of the movable door 7 is in a semi-circular arc shape, and one side of the movable door 7 is hinged to the side wall of the outer shell 22, and the other side is fixed to the side wall of the outer shell 22 through a lock 8. When inspection is needed, the movable door 7 can be opened to observe the internal conditions of the drying mechanism 2.

[0053] In addition, to improve the safety of the spin dryer, a relay switch can be set on the movable door 7. When the door is not closed properly, the rotating motor 26 cannot be started, so that the drying mechanism 2 cannot work, which is beneficial to enhancing the safety of the spin dryer operation.

[0054] The implementation principle of this embodiment is as follows: during operation, the rotating motor 26 is started, so that the rotating shaft 27 drives the inner cylinder 23 to rotate around its circumferential side. Then, the feeding mechanism 1 conveys the vegetables to be dried to the open end at the upper end of the inner cylinder 23, so that the vegetables to be dried enter the inner cylinder 23. Under the action of centrifugal force, the water on the vegetables penetrates through the filter holes 231 into the gap between the outer shell 22 and the inner cylinder 23, thereby separating the vegetables from the water. Then, the scraping cylinder 31 is started to make the scraping plate 32 close to the side wall of the inner cylinder 23. After the dried vegetables hit the scraping plate 32, the dried vegetables fall from the open end at the lower end of the inner cylinder 23 into the conveying mechanism 4, and the conveying mechanism 4 conveys the dried vegetables to the next process.

[0055] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
