[0016] 1. The present invention arranges a plurality of particle forming components on a granulation disc, each particle forming component includes a particle forming mold shell that is slidably fitted in a radial cavity and can realize opening and closing of the mold, and a spherical forming cavity is arranged inside the particle forming mold shell, and a second flow hole that is connected to the spherical forming cavity is opened on the top of the particle forming mold shell.

[0039] In this embodiment of the present invention, a closed docking cover 105 coaxial with the granulating disc 101 is fixedly provided on the top of the granulating disc 101, and the closed docking cover 105 is fixedly installed at the bottom of the extrusion discharge port of the disc granulator, so that the stirred and mixed food raw materials can be pressed into the closed docking cover 105, and then extruded from the various raw material extrusion holes 103 on the granulating disc 101. An inclined material guide table 106 coaxial with the granulating disc 101 is fixedly provided at the bottom of the granulating disc 101. After granulation, the spherical granular food falls onto the inclined material guide table 106 and then gradually rolls down into the collection box. An L-shaped support seat 107 corresponding to the radial cavity 102 is fixedly provided on the peripheral side of the closed docking cover 105, and a first elastic member 108 is provided inside the L-shaped support seat 107.

[0040] In this embodiment of the present invention, a mounting frame 304 located outside the radial cavity 102 is fixedly provided at one end of the particle forming tube 301, and a positioning support portion 305 is fixedly provided on one side of the mounting frame 304. In order to achieve better automated control of the granulation process, a pressure sensor can be installed on the inner side of the L-shaped support seat 107, and the positioning support portion 305 is used to trigger the corresponding pressure sensor. A first limiting channel 306 corresponding to the second particle discharge hole 303 is opened at the bottom of the particle forming tube 301, and the first limiting channel 306 is connected to the corresponding second particle discharge hole 303;

[0041] An axial extension frame 307 is fixedly installed on the side surface of the mounting frame 304, and a plurality of positioning portions 308 are arranged in a linear array on the axial extension frame 307. An axial engaging portion 309 that slides with the mounting frame 304 is arranged on the opposite side of the axial extension frame 307. A magnetic plate 310 is fixedly installed on the end of the axial engaging portion 309 close to the positioning support portion 305 (the magnetic plate 310 is attached to the surface of the mounting frame 304 in the initial state), and the electromagnet installed on the surface of the mounting frame 304 and the permanent magnet on the corresponding magnetic plate 310 magnetically repel each other.

[0042] In this embodiment of the present invention, the particle forming component 4 also includes a rotating separation ring 404 corresponding to the positioning portion 308 one by one, the rotating separation ring 404 is rotatably connected to the corresponding positioning portion 308, the axial meshing portion 309 and each rotating separation ring 404 on one side thereof are mutually meshed, and two annular pushing portions 405 are rotatably arranged on the inner wall of the rotating separation ring 404, and the particle forming mold shell 401 is slidably fitted inside the particle forming tube 301 (specifically, a closed piston is arranged at the end of the particle forming tube 301 away from the mounting frame 304, and the closed piston is slidably fitted inside the corresponding radial cavity 102), and an L-shaped linkage portion 406 (such as Figure 7 and Fig.11As shown in the figure, when the control electromagnet is energized and magnetized, the magnetic plate 310 is driven by the magnetic repulsion force to move the axial meshing portion 309, driving each rotating separation ring 404 to rotate synchronously, and during the rotation of the rotating separation ring 404, the two symmetrically arranged particle forming mold shells 401 are moved away from each other, thereby realizing the demolding of the formed spherical particle food.

[0043] In this embodiment of the present invention, a plurality of second limiting channels 109 are arranged in an annular array at the bottom of the granulating disc 101, and the second limiting channels 109 are arranged in a one-to-one correspondence with the radial cavities 102. The second limiting channels 109 are connected to the corresponding radial cavities 102 through a plurality of first particle discharge holes 104, and the L-shaped linkage portion 406 is slidably matched inside the corresponding first limiting channel 306 and the second limiting channel 109. The matching relationship between the second limiting channel 109 and the L-shaped linkage portion 406 can ensure that the particle forming tube 301 will not rotate during the movement, and at the same time, the matching relationship between the first limiting channel 306 and the L-shaped linkage portion 406 can ensure that the particle forming mold shell 401 will not rotate during the movement;

[0044] The particle forming mechanism 2 also includes a plurality of reset components 5 arranged in a linear array. The reset components 5 include two relatively arranged connection plates 501, which are fixedly mounted in the mounting holes 407 on the surfaces of the corresponding L-shaped linkage parts 406. A second elastic member 502 is arranged between the two relatively arranged connection plates 501. The reset components 5 at both ends of the particle forming tube 301 are fixedly mounted on the axial extension frame 307. When the control electromagnet is energized and magnetized, the magnetic plate 310 is driven by the magnetic repulsion force to move the axial meshing part 309 and drive each rotating separation ring 404 to rotate synchronously. In this process, The L-shaped linkage part 406 is pushed along the annular trajectory by the annular pushing part 405 until the L-shaped linkage part 406 moves and abuts against the inner end of the corresponding first limiting channel 306. At this time, the two particle forming mold shells 401 on each particle forming component 4 are completely separated, and each second elastic member 502 is in a compressed state, thereby realizing the demoulding of the formed spherical particle food. After the demoulding of the spherical particle food in the spherical molding cavity 402 is completed, the electromagnet is controlled to be powered off and demagnetized, so that a part of the L-shaped linkage part 406 ( Fig.11 The L-shaped linkage part 406 on the right side in the middle moves in the opposite direction to reset. During this process, the L-shaped linkage part 406 on the right side is used to push the corresponding annular pushing part 405. Similarly, the L-shaped linkage part 406 on the left side also pushes the corresponding annular pushing part 405, thereby driving each rotating separation ring 404 to rotate counterclockwise synchronously until the magnetic plate 310 is against the mounting frame 304 again. At this time, the two particle forming mold shells 401 on each particle forming component 4 are re-fitted to complete the mold closing.

[0045] In the initial state, the rotating separation ring 404 is coaxial with the first flow hole 302, and the first flow hole 302 is aligned with the corresponding raw material extrusion hole 103. After the granulator is operated once, the food raw materials in the closed docking cover 105 are extruded from the various raw material extrusion holes 103 on the granulation disk 101 into the spherical forming cavity 402, and then the various particle forming mechanisms 2 are controlled to move radially to the outside of the granulation disk 101 synchronously until the positioning support part 305 on each particle forming mechanism 2 abuts against the corresponding L-shaped support seat 107. At this time, the controller receives the pressure signal transmitted by the pressure sensor on each L-shaped support seat 107, and each first flow hole 302 deviates from the raw material extrusion hole 103 and is aligned with the corresponding first particle discharge hole 104. (the first particle discharge hole 104 is aligned with the corresponding second particle discharge hole 303), and then the electromagnet is controlled to be energized and magnetized, and the magnetic plate 310 is driven by the magnetic repulsion force to move the axial meshing portion 309 to drive each rotating separation ring 404 to rotate synchronously. In this process, the annular pushing portion 405 is used to push the L-shaped linkage portion 406 along the annular trajectory until the L-shaped linkage portion 406 moves and abuts against the inner end of the corresponding first limiting channel 306. At this time, the two particle forming mold shells 401 on each particle forming component 4 are completely separated, and the formed spherical particle food in each spherical forming cavity 402 falls through the second particle discharge hole 303 and the first particle discharge hole 104 to the inclined material guide table 106, and is rolled down by the inclined material guide table 106 to be collected;

[0046] Then, the electromagnets are de-energized and demagnetized at the same time, so that the rotating separation rings 404 are synchronously rotated counterclockwise (eg, Figure 7 As shown), until the magnetic plate 310 rests against the mounting frame 304 again, at which time the two particle forming mold shells 401 on each particle forming assembly 4 are refitted to complete the mold closing, and then each particle forming mechanism 2 is controlled to synchronously move radially toward the inner side of the granulating disk 101 until the positioning support portion 305 on each particle forming mechanism 2 is separated from the corresponding L-shaped support seat 107 and returns to the initial position, at which time each first elastic member 108 restores its original length, and each second particle discharge hole 303 deviates from the first particle discharge hole 104 and is realigned with the corresponding raw material extrusion hole 103, and each first flow hole 302 is aligned with the corresponding raw material extrusion hole 103 again, and finally the granulator is controlled to operate once again so that the food raw materials in the closed docking cover 105 are extruded from each raw material extrusion hole 103 on the granulating disk 101 into the spherical forming cavity 402, and the granulation processing of the next batch of spherical particle food is realized according to the same control method as above, thereby realizing the continuous production of particle food.

[0047] Specific embodiment 2, on the basis of specific embodiment 1, a first air guiding cavity 110 and a second air guiding cavity 111 are respectively opened at the center position inside the granulation disk 101, the second air guiding cavity 111 is arranged above the first air guiding cavity 110 and the two are arranged coaxially, the first air guiding cavity 110 and each radial cavity 102 on its circumferential side are connected through an air vent 112, and a plurality of air guiding channels 113 connected to the second air guiding cavity 111 are arranged in an annular array inside the granulation disk 101, the air guiding channels 113 are arranged one-to-one with the radial cavity 102, and the air guiding channels 113 are connected to the corresponding radial cavity 102 through an air sweeping hole 114.

[0048] In this embodiment of the present invention, the present invention also includes a first tube group 6 and a second tube group 7; wherein the first tube group 6 includes a first gas pipe 601 fixedly installed at the bottom of the granulating disc 101 and connected to the first gas guide cavity 110, and a first solenoid valve 602 is installed on the first gas pipe 601; the second tube group 7 includes a second gas pipe 701 fixedly installed at the bottom of the granulating disc 101 and connected to the second gas guide cavity 111, and a second solenoid valve 702 is installed on the second gas pipe 701. It should be noted that the first gas pipe 601 and the second gas pipe 701 are both connected to an air supply device, and an air outlet is installed at the air supply device. The purified air flow can be delivered to the first air guide cavity 110 and the second air guide cavity 111. At the same time, a pressure relief valve (not shown in the figure) is installed on the branch pipe of the first air delivery pipe 601; the controller controls each first solenoid valve 602 to open at the same time, so that the air enters the first air guide cavity 110 along each first air delivery pipe 601, and then flows into each radial cavity 102 through the vent hole 112. Since a closed piston is provided at the end of the particle forming tube 301 away from the mounting frame 304, the closed piston is slidably matched in the corresponding radial cavity 102, so the air entering the radial cavity 102 pushes each particle. The forming mechanism 2 synchronously moves radially toward the outside of the granulating disc 101 until the positioning support portion 305 on each of the particle forming mechanisms 2 abuts against the corresponding L-shaped support seat 107. At this time, the controller receives the pressure signal transmitted by the pressure sensor on each L-shaped support seat 107 and controls each of the first solenoid valves 602 to be closed at the same time. When the two particle forming mold shells 401 on each particle forming component 4 are completely separated, the controller controls each of the second solenoid valves 702 to be opened at the same time, so that the external air enters the second air guide cavity 111 along each of the second air delivery pipes 701, and then flows into each of the air sweeping holes through the air guide channel 113. 114, the air flow entering into each air sweeping hole 114 is discharged from the first particle discharge hole 104 along the spherical forming cavity 402, thereby realizing the purging of the inside of the spherical forming cavity 402, and at the same time can accelerate the demolding of the spherical particle food after forming, thereby improving the production efficiency of the particle food, after purging for a period of time, each second solenoid valve 702 is closed at the same time, and then each first solenoid valve 602 is controlled to be opened again at the same time, so as to realize the pressure relief inside each radial cavity 102, and each particle forming mechanism 2 after the pressure relief returns to the initial position, and the continuous production of the particle food can be realized in the subsequent control method as mentioned above.

[0049] The overall working process of this application is:

[0050] In the initial state, the rotating separation ring 404 is coaxial with the first flow hole 302, and the first flow hole 302 is aligned with the corresponding raw material extrusion hole 103. The granulator is operated once so that the food raw materials in the closed docking cover 105 are squeezed out from the raw material extrusion holes 103 on the granulating disk 101 to the inside of the spherical forming cavity 402. Then, the controller controls the first solenoid valves 602 to open at the same time, so that the air enters the first air guide cavity 110 along the first air delivery pipes 601, and then flows into the radial cavities 102 through the air holes 112. The air entering the radial cavities 102 pushes the particle forming mechanisms 2 to move radially to the outside of the granulating disk 101 synchronously until the positioning support parts 305 on the particle forming mechanisms 2 abut against the corresponding L-shaped support seats 107. At this time, the controller receives the pressure signal transmitted by the pressure sensors on the L-shaped support seats 107 and controls Each first solenoid valve 602 is closed at the same time. At this time, each first flow hole 302 deviates from the raw material extrusion hole 103 and is aligned with the corresponding first particle discharge hole 104 (the first particle discharge hole 104 is aligned with the corresponding second particle discharge hole 303). Then, the electromagnet is controlled to be energized and magnetized. The magnetic plate 310 is driven by the magnetic repulsion force to move the axial meshing part 309 to drive each rotating separation ring 404 to rotate synchronously. In this process, the annular pushing part 405 is used to push the L-shaped linkage part 406 along the annular trajectory until the L-shaped linkage part 406 moves and abuts against the inner end of the corresponding first limiting channel 306. At this time, the two particle forming mold shells 401 on each particle forming component 4 are completely separated, and the formed spherical particle food in each spherical forming cavity 402 falls through the second particle discharge hole 303 and the first particle discharge hole 104 to the inclined material guide table 106, and is rolled down by the inclined material guide table 106 to be collected;

[0051] Then, the electromagnets are de-energized and demagnetized at the same time, so that the rotating separation rings 404 are synchronously rotated counterclockwise (eg, Figure 7As shown), until the magnetic plate 310 rests against the mounting frame 304 again, at which time the two particle forming mold shells 401 on each particle forming assembly 4 are re-fitted to complete the mold closing, and then the controller controls each second solenoid valve 702 to be opened simultaneously, so that the external air enters the second air guide cavity 111 along each second air delivery pipe 701, and then flows into each air sweeping hole 114 through the air guide channel 113, and the air flow entering each air sweeping hole 114 passes through the spherical forming cavity 402 and is discharged from the first particle discharge hole 104, thereby achieving the purge of the inside of the spherical forming cavity 402 and accelerating the demoulding of the spherical particle food after the formation, and closing each second solenoid valve 702 at the same time after a period of purge, and then controlling Each first solenoid valve 602 is controlled to open again to achieve pressure relief in each radial cavity 102. After the pressure relief, each particle forming mechanism 2 returns to the initial position. At this time, each first elastic member 108 recovers its original length, and each second particle discharge hole 303 deviates from the first particle discharge hole 104 and is realigned with the corresponding raw material extrusion hole 103. Each first flow hole 302 is aligned with the corresponding raw material extrusion hole 103 again. Finally, the granulator is controlled to operate again so that the food raw materials in the closed docking cover 105 are extruded from the raw material extrusion holes 103 on the granulating disc 101 into the spherical forming cavity 402. The granulation process of the next batch of spherical particle food is realized according to the same control method as above, thereby realizing the continuous production of particle food.
