[0030] Please see Figures 1 to 6 The image shows a continuous liquid nitrogen granulation freeze-drying device according to the first embodiment of the present invention. It is characterized by including a feeding mechanism, a transport mechanism, and a freeze dryer 10. The transport mechanism includes a vertical lifting assembly, a bearing assembly rotatably connected to the vertical lifting assembly, a first conveying structure and a second conveying structure located below the vertical lifting assembly, and a tray trolley 80. The feeding mechanism is used to transport the tray 60 to the bearing assembly, and the tray trolley 80 is used to transport the tray 60 to the freeze dryer 10.

[0031] Understandably, this utility model, by setting up a transportation mechanism, which includes a vertical lifting component and a carrying component, allows the probiotic balls to be loaded into a tray 60 after preparation. The tray 60 is then transported to the carrying component via a feeding mechanism. The vertical lifting component then transports the carrying component carrying the tray 60 downwards. After reaching the first and second conveying structures, the carrying component is slightly tilted to transport the tray 60 to either the first or second conveying structure. Finally, the tray trolley 80 transports the tray 60 into the freeze dryer 10.

[0032] This invention changes the planar conveying to vertical conveying, which greatly saves lateral space.

[0033] Specifically, in this embodiment, the transport mechanism includes a base 30 and a housing disposed on the base 30. The housing includes a lateral extension 40 and a longitudinal extension 20 disposed above the lateral extension 40. A lateral liquid nitrogen tunnel is formed in the lateral extension 40, and a longitudinal liquid nitrogen tunnel is formed in the longitudinal extension 20. The lateral liquid nitrogen tunnel and the longitudinal liquid nitrogen tunnel are connected.

[0034] Understandably, the cryogenic liquid nitrogen tunnel inside the shell can provide comprehensive protection for the probiotic balls and transport them to the freeze dryer 10. The liquid nitrogen in the tunnel is delivered into the shell through a liquid nitrogen storage tank and pipeline (existing technology, not shown in the figure).

[0035] Furthermore, the outer surface of the longitudinal extension 20 is provided with a first mounting shell 21. The vertical lifting assembly includes a ball screw 72 and a guide rod 73 located in the first mounting shell 21, and a servo motor 77 connected to the ball screw 72. The bearing assembly includes a sliding block 74 threadedly connected to the ball screw 72, a bearing frame 75 fixedly connected to the sliding block 74, a transfer roller 76 disposed in the bearing frame 75, and a guide block fixedly connected to the bearing frame 75. The guide block is slidably connected to the guide rod 73, and the bearing frame 75 is located in the longitudinal liquid nitrogen tunnel. The first conveying structure is a first conveying roller 70 located in the transverse liquid nitrogen tunnel, and the second conveying structure is a second conveying roller 71 located in the transverse liquid nitrogen tunnel. The first conveying roller 70 and the second conveying roller 71 are arranged opposite to each other. The lateral extension 40 is provided with a first opening 41 and a second opening 42. The first opening 41 is located at the first conveying structure, and the second opening 42 is located at the second conveying structure. There are two freeze dryers 10, and the two freeze dryers 10 are respectively provided with a first inlet 78 and a second inlet 79. The first inlet 78 corresponds to the first opening 41, and the second inlet 79 corresponds to the second opening 42. The base 30 is provided with a first slide rail 84 extending into the freeze dryer 10. The first slide rail 84 is provided with a first slide rail cylinder 85. The first slide rail cylinder 85 is provided with a sliding plate 83. The sliding plate 83 is provided with a second slide rail 82 perpendicular to the first slide rail 84. The second slide rail 82 is provided with a second slide rail cylinder 81. The second slide rail cylinder 81 is provided with a material tray trolley 80.

[0036] Understandably, when the tray 60 containing probiotic balls is transferred to the support plate, the servo motor 77 rotates, driving the ball screw 72 to rotate, which in turn causes the sliding block 74, which is threaded to it, to move downward. The guide rod 73 can limit the movement trajectory of the guide block, thereby enabling the support plate to drive the connecting rod and the support plate to move up and down stably along the preset trajectory, ensuring the stable transportation of the tray 60. The support plate stops when it is about to reach the first and second conveying structures, and then the transfer roller 76 transports the tray 60 to one side until the tray 60 enters the first conveying roller 70 or the second conveying roller 71. Taking the first conveying roller 70 as an example, the first conveying roller 70 transports the tray 60 to the tray trolley 80. Then the second slide rail cylinder 81 drives the tray trolley 80 to move along the second slide rail 82. After reaching the specified distance, the first slide rail cylinder 85 drives the second slide rail cylinder 81 and the tray trolley 80 to move into the freeze dryer 10 until they reach the corresponding position inside the freeze dryer 10. It should be noted that the freeze dryer 10 has multiple layers inside, and there are special tracks inside to transport the tray trolley 80 to the corresponding layer. This is not the point of invention of this application and will not be elaborated here. The material tray 60 can be alternately transported to different freeze dryers 10 via the first conveyor roller 70 and the second conveyor roller 71, improving production efficiency. The transfer roller 76, the first conveyor roller 70, and the second conveyor roller 71 are all driven by motors. Attention must be paid to edge sealing between the first opening 41 and the first inlet / outlet 78, as well as between the second opening 42 and the second inlet / outlet 79, to prevent leakage of cryogenic liquid nitrogen. A clearance hole (not shown in the figure, but easily understood) is provided between the first mounting shell 21 and the longitudinal extension 20 for the guide block and the sliding block 74 to slide.

[0037] Furthermore, the feeding mechanism includes a second mounting shell 22 disposed on the housing, the second mounting shell 22 being used to place the material tray 60, and a material tray inlet 221 passing through the second mounting shell 22 and the housing; the feeding mechanism also includes a liquid nitrogen granulator 50, the liquid nitrogen granulator 50 having a nozzle 51, and a through hole for the nozzle 51 to pass through on the second mounting shell 22.

[0038] Understandably, the initial step in liquid nitrogen granulation is to deliver the probiotic stock solution to the liquid nitrogen granulator 50, where it is formed into droplets by the dripping system and dripped into the circulating liquid nitrogen channel. During the flow, the droplets rapidly freeze into solid probiotic balls within 3-4 seconds. Then, the probiotic balls are quickly separated from the liquid nitrogen through a sieve, and the probiotic balls are output through the nozzle 51. Since the material tray 60 needs to be pre-cooled, the space inside the second mounting shell 22 is connected to the longitudinal liquid nitrogen tunnel. When probiotic balls need to be loaded, the operator places the material tray 60 in the second mounting shell 22 to cool it. After a few minutes, the probiotic balls are sprayed directly from the nozzle 51 into the material tray 60 inside the second mounting shell 22. Then, the operator places the material tray 60 from the material tray inlet 221 into the transfer roller 76. Finally, the sliding door 222 is closed to prevent leakage of cryogenic liquid nitrogen.

[0039] It should be noted that electrical components located in the liquid nitrogen tunnel need to be protected from freezing.

[0040] In summary, the continuous liquid nitrogen granulation freeze-drying device in the above embodiments of this utility model, by setting up a transport mechanism, wherein the transport mechanism includes a vertical lifting component and a carrying component, after the probiotic balls are prepared, they are loaded with a material tray, and the material tray is transported to the carrying component by the feeding mechanism. Then, the carrying component carrying the material tray is transported downward by the vertical lifting component. After reaching the first conveying structure and the second conveying structure, the carrying component is tilted slightly to transport the material tray to the first conveying structure or the second conveying structure. Finally, the material tray is transported to the freeze dryer by the material tray trolley.

[0041] This invention changes the planar conveying to vertical conveying, which greatly saves lateral space.
