[0008] As a further scheme of the present application: the centrifugal drying cylinder comprises a rotating outer cylinder, a rotating inner cylinder is fixedly connected to the middle position of the inner cavity of the rotating outer cylinder, and support seats are nested at the two ends of the rotating outer cylinder and are fixedly installed in the drying cavity.

[0009] As a further scheme of the present application: the rotating outer cylinder comprises a first cylinder body and a second cylinder body, the number of the first cylinder bodies is two, the first cylinder bodies are symmetrically arranged at the two ends of the second cylinder body, the inner diameter of the first cylinder body is smaller than that of the second cylinder body, and a plurality of axial through grooves are formed in the side surface of the second cylinder body.

[0010] As a further scheme of the present application: the support seat comprises a support frame, four bearing seats are arranged on the inner side of the support frame, a drive gear is installed on the inner side of each bearing seat, the four drive gears are in mesh with the side surface of the first cylinder body, and the center position of one of the drive gears is connected to the output shaft of the motor through a shaft coupling.

[0011] As a further scheme of the present application: the rotating inner cylinder comprises an inner cylinder body, at least four permanent magnet strips are arranged on the side surface of the inner cylinder body, the number of the permanent magnet strips is even, radial through grooves are formed between the permanent magnet strips, and the length of the inner cylinder body is equal to the length of the second cylinder body.

[0014] As a further scheme of the present application: rotating heads are rotatably connected to the central positions of the two ends of the conveying box body, and the end surfaces of the rotating heads are arc surfaces.

[0015] The present application has the following beneficial effects:

[0016] 1. In this invention, since rotating heads are rotatably connected to the center positions of both ends of the conveying box, and the end faces of the rotating heads are arc-shaped, when the conveying box is placed into the centrifugal drying cylinder, multiple conveying boxes are in contact with each other through the rotating heads. The rotating heads can rotate, and the end faces of the rotating heads are arc-shaped, which can ensure that the contact area between multiple conveying boxes is small. Therefore, it can ensure that the rotation speeds of multiple conveying boxes are not consistent. When the conveying boxes in the centrifugal drying cylinder are full, it is only necessary to insert a new conveying box from one end of the centrifugal drying cylinder, and the conveying boxes at the other end of the centrifugal drying cylinder will be automatically squeezed out. This realizes feeding and unloading while the centrifugal drying cylinder is rotating at a high speed, without stopping the rotation of the centrifugal drying cylinder, which greatly reduces the frequency of shutting down the centrifugal drying cylinder. On the one hand, it can reduce the load on the side drive gear of the centrifugal drying cylinder, and on the other hand, it can reduce the energy consumption caused by frequent starts and stops of the centrifugal drying cylinder.

[0017] 2. In this invention, the first cylinder drives the material conveying box through friction. At this time, the rotation speed of the material conveying box is less than that of the first cylinder. When the material conveying box enters the second cylinder, that is, the rotating inner cylinder, the material conveying box is subjected to the dual action of friction on the inner wall of the rotating inner cylinder and magnetic attraction between the permanent magnet block and the permanent magnet strip because the magnetic poles of the opposing surfaces of the permanent magnet block and the permanent magnet strip are opposite. This ensures that the rotation speed of the material conveying box gradually increases in the centrifugal drying cylinder and eventually synchronizes with the rotation speed of the centrifugal drying cylinder. The high-speed material conveying box can centrifuge the vegetables inside the material conveying box, so that the water adhering to the surface of the vegetables is carried out by the centrifugal force. The hot air conveyed to the rotating inner cylinder through the air inlet can dry the vegetables. Under the dual action of centrifugal force and hot air, the vegetables can be dried quickly, which improves the efficiency of vegetable drying. Attached Figure Description

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] As Figures 1-8 shown, the present application discloses a kind of food processing equipment, including vegetable drying cabinet 1, the top of one end of vegetable drying cabinet 1 is provided with air inlet port 2, air inlet port 2 transports hot air to the inner cavity of vegetable drying cabinet 1, the output end of hot air fan is connected to the outer side of one end of air inlet port 2, centrifugal drying cylinder 3 is arranged in the inner cavity of vegetable drying cabinet 1, centrifugal drying cylinder 3 generates centrifugal force by high-speed rotation, the number of material conveying box 4 is several, several material conveying boxes 4 are arranged in one word in the inner cavity of centrifugal drying cylinder 3, the end surface between the inner wall of centrifugal drying cylinder 3 and material conveying box 4 is attracted by magnetic force, the direction of magnetic force is perpendicular to the inner wall section of centrifugal drying cylinder 3, isolation plate 5 is provided in the inner cavity of vegetable drying cabinet 1 and close to one end of air inlet port 2, the top surface of the outer side of one end of isolation plate 5 is rotatably connected with folding plate 52;

[0030] In use, the vegetables can be placed in the material conveying box 4, and then the material conveying box 4 is placed into the centrifugal drying cylinder 3 through one end of the vegetable drying cabinet 1. The high-speed rotation of the centrifugal drying cylinder 3 can gradually synchronize the high-speed rotation of the material conveying box 4 through the dual action of magnetic attraction and friction. The high-speed rotation of the material conveying box 4 can generate centrifugal force on the vegetables in the material conveying box 4, and the water adhered to the vegetables during cleaning can be removed by the centrifugal force. Since the outside end of the air inlet port 2 is connected to the output end of the hot air blower, after the hot air blower is turned on, the hot air blower can deliver hot air to the inner cavity of the vegetable drying cabinet 1 through the air inlet port 2, and the vegetables in the material conveying box 4 can be dried.

[0031] As shown in Figure 2 and Figure 8 , the inside of the vegetable drying cabinet 1 is provided with a drying cavity 11, and the side wall of the drying cavity 11 is provided with a limiting sliding groove 12 near the position of the isolation plate 5. The two sides of the isolation plate 5 are fixedly connected with limiting sliding blocks which are mutually fitted with the limiting sliding groove 12. The top end of the folding plate 52 is connected with the top wall of the drying cavity 11 through a hinge. The top surface of the vegetable drying cabinet 1 is fixedly connected with a hydraulic cylinder 51. The output end of the hydraulic cylinder 51 is fixedly connected with the top surface of the limiting sliding block through a hydraulic rod. The folding plate 52 is composed of a plurality of long plates which are connected with each other.

[0032] Specifically, when the hot air blower delivers hot air to the drying cavity 11 inside the vegetable drying cabinet 1, the limiting sliding block is pushed by the hydraulic cylinder 51, and the limiting sliding block drives the isolation plate 5, so that the bottom surface of the isolation plate 5 is in contact with the bottom surface of the drying cavity 11. At this time, the folding plate 52 is completely unfolded, which can seal the port of the drying cavity 11, so as to ensure that the hot air delivered by the hot air blower can pass through the centrifugal drying cylinder 3 and be discharged from the other end of the drying cavity 11. When the vegetables in the material conveying box 4 are dried and need to be taken out, the limiting sliding block can be pulled by the hydraulic cylinder 51, and the limiting sliding block drives the isolation plate 5 to be lifted. After the height of the isolation plate 5 exceeds the center of the centrifugal drying cylinder 3, the material conveying box 4 is taken out from the bottom surface of the centrifugal drying cylinder 3. At this time, the material conveying box 4 can cooperate with the isolation plate 5 to play a guiding role, so as to ensure that the hot air cannot flow out from the port of the drying cavity 11 at the end of the isolation plate 5.

[0033] As shown in Figure 3 , the centrifugal drying cylinder 3 comprises a rotating outer cylinder 31. The rotating inner cylinder 33 is fixedly connected to the inner cavity of the rotating outer cylinder 31. The two ends of the rotating outer cylinder 31 are nested with support seats 32, and the support seats 32 are fixedly installed in the drying cavity 11.

[0034] The support seat 32 is used to support the rotating outer cylinder 31. Since the rotating inner cylinder 33 is fixedly installed in the inner cavity of the rotating outer cylinder 31, when the rotating outer cylinder 31 rotates, the rotating inner cylinder 33 can be driven to rotate synchronously.

[0035] AsFigure 5 As shown in the figure, the rotating outer cylinder 31 comprises a first cylinder body 311 and a second cylinder body 312, the number of the first cylinder body 311 is two, which is symmetrically arranged at both ends of the second cylinder body 312, the inner diameter of the first cylinder body 311 is smaller than that of the second cylinder body 312, and a plurality of axial through grooves 313 are formed in the side surface of the second cylinder body 312;

[0036] As shown in the figure, Figure 4 The support seat 32 comprises a support frame 321, the inner side of the support frame 321 is provided with four bearing seats 322, the inner side of each bearing seat 322 is mounted with a driving gear 323, and the four driving gears 323 are engaged with the side surface of the first cylinder body 311, wherein the center position of one of the driving gears 323 is connected with the output shaft of the motor through a shaft coupling.

[0037] As shown in the figure, Figure 6 The rotating inner cylinder 33 comprises an inner cylinder body 331, the side surface of the inner cylinder body 331 is provided with at least four permanent magnet strips 332, the number of the permanent magnet strips 332 is even, radial through grooves 333 are formed between the permanent magnet strips 332, the length of the inner cylinder body 331 is equal to that of the second cylinder body 312, and the inner diameter of the inner cylinder body 331 is equal to that of the first cylinder body 311;

[0038] As shown in the figure, Figure 7 The material conveying box 4 comprises a conveying box body 41, the top surface of the conveying box body 41 is rotatably connected with a conveying box cover 42, a plurality of through grooves are formed in the surface of the conveying box body 41 and the conveying box cover 42, two moving wheels 43 are mounted on the two sides of the conveying box body 41, the maximum distance between the moving wheels 43 on the two sides of the conveying box body 41 is equal to the inner diameter of the inner cylinder body 331, and permanent magnet blocks 44 are fixedly connected to the middle positions of the two sides of the conveying box body 41, the magnetic poles of the permanent magnet blocks 44 are opposite to those of the facing surfaces of the permanent magnet strips 332;

[0039] When the material conveying box 4 enters the centrifugal drying cylinder 3, it first enters the first cylinder body 311, at this time the first cylinder body 311 brings the material conveying box 4 through friction, and at this time the rotating speed of the material conveying box 4 is less than that of the first cylinder body 311, when the material conveying box 4 enters the second cylinder body 312, that is, the rotating inner cylinder 33, because the magnetic poles of the permanent magnet blocks 44 are opposite to those of the facing surfaces of the permanent magnet strips 332, the material conveying box 4 is subjected to the double actions of the friction force of the inner wall of the rotating inner cylinder 33 and the magnetic attraction force between the permanent magnet blocks 44 and the permanent magnet strips 332, which ensures that the rotating speed of the material conveying box 4 gradually increases in the centrifugal drying cylinder 3, and finally synchronizes with the rotating speed of the centrifugal drying cylinder 3, the high-speed material conveying box 4 can perform centrifugal treatment on the vegetables in the material conveying box 4, so that the water adhered to the surface of the vegetables is brought out by the centrifugal force, and the hot air conveyed in the rotating inner cylinder 33 by the air inlet port 2 can dry the vegetables, so that the vegetables can be quickly dried under the double actions of the centrifugal force and the hot air, thereby improving the drying efficiency of the vegetables;

[0040] When the vegetable drying in the material conveying box 4 is finished, the material conveying box 4 can be moved from the rotating inner cylinder 33 to another first cylinder body 311, at this time the material conveying box 4 is not affected by the magnetic force, so the rotating speed of the material conveying box 4 will be reduced;

[0041] Since the two end center positions of the conveying box body 41 are rotationally connected with the rotating head 45, and the end surface of the rotating head 45 is arc-shaped, when the conveying box body 41 is placed into the centrifugal drying cylinder 3, the plurality of conveying box bodies 41 are in contact with each other through the rotating head 45, the rotating head 45 can rotate, and the end surface of the rotating head 45 is arc-shaped, which can ensure that the contact area between the plurality of conveying box bodies 41 is small, so that the rotating speed of the plurality of conveying box bodies 41 is inconsistent. When the conveying box bodies 41 in the centrifugal drying cylinder 3 are fully arranged, only one conveying box body 41 needs to be inserted from one end of the centrifugal drying cylinder 3, and the conveying box body 41 at the other end of the centrifugal drying cylinder 3 will be automatically extruded. In this way, the feeding and discharging can be realized under the condition that the centrifugal drying cylinder 3 rotates at a high speed, without stopping the rotation of the centrifugal drying cylinder 3, which greatly reduces the frequency of stopping the centrifugal drying cylinder 3. On the one hand, it can reduce the load of the driving gear 323 on the side of the centrifugal drying cylinder 3, and on the other hand, it can also reduce the energy consumption caused by frequent starting of the centrifugal drying cylinder 3.

[0042] The above describes one embodiment of the present application in detail, but the above description is only a preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made according to the scope of the present application should still belong to the scope of the present application.
