A freeze-drying apparatus for preparing freeze-dried powder

Abstract

This utility model discloses a freeze-drying device for preparing freeze-dried powder, relating to the technical field of freeze-drying equipment. The utility model includes a freezer chamber, inside which a support component is provided. Through the connection of a folding component and a limiting component, when the limiting component is in its initial state, it engages with the movable and fixed parts of the folding component, locking the folding component and preventing unnecessary rotation. When the material rack and folding component need to be pushed into the freezer chamber, the limiting component is pushed downwards, separating it from the fixed part of the folding component and releasing the limiting fixation. Then, the material rack and folding component continue to be pushed into the freezer chamber. Under the compression and guiding action of the support component inside the freezer chamber, the folding component bends until the entire material rack enters the freezer chamber. This eliminates the need to handle each pallet individually, reducing labor intensity.

Description

Technical Field

[0001] This utility model belongs to the technical field of freeze-drying equipment, and specifically relates to a freeze-drying equipment for preparing freeze-dried powder. Background Technology

[0002] Freeze-dried powder is a dry powder or solid obtained by freeze-drying water-containing liquid materials, such as pharmaceutical solutions, food slurries, and cosmetic concentrates. Freeze-dried powder has significant advantages such as high component stability, good rehydration properties, and strong long-term storage characteristics. Therefore, it has been widely and importantly used in the biopharmaceutical field, such as the production of vaccines, antibodies, and recombinant protein preparations; in the food field, such as the processing of freeze-dried fruits and vegetables and probiotic powders; and in the cosmetic field, such as the preparation of freeze-dried essences and freeze-dried powder masks, becoming an indispensable product in modern industrial production.

[0003] Some freeze-drying equipment uses a fixed-installation structure for its built-in material racks, meaning the racks remain in a fixed position inside the equipment. Workers must first place the material pallets containing the materials onto an external transfer trolley, and then manually move each pallet from the trolley to the fixed racks inside the equipment. This process is tedious, especially when there are many pallets, significantly increasing the workload for the workers. Utility Model Content

[0004] To address the problem that manually moving material pallets from transfer carts to fixed material racks inside equipment is cumbersome, especially when there are many material pallets, significantly increasing the labor intensity of workers, this utility model proposes a freeze-drying device for preparing freeze-dried powder to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a freeze-drying device for preparing freeze-dried powder, including a freezing chamber. The freezing chamber has a support component inside, a material rack is provided on the top of the support component, and a folding component is provided on the bottom of the material rack. The folding component has a limiting component and a telescopic component inside. The support component is used to support the material rack, the limiting component is used to lock the folding component, and the telescopic component is used to adjust the height of the material rack.

[0007] Furthermore, the support assembly includes a fixed plate, which is fixedly connected to the inside of the freezer. A support column is fixedly connected to the top of the fixed plate, and a support plate is fixedly connected to the top of the support column. A first wheel frame is fixedly connected to the bottom of the support plate, and a guide wheel is rotatably connected inside the first wheel frame.

[0008] Furthermore, the folding assembly includes a fixed column, with a pin rotatably connected inside the fixed column, and a rotating column fixedly connected to the end of the pin. There are multiple sets of the fixed column, pin, and rotating column, and the fixed column is fixedly connected to the bottom of the material rack.

[0009] Furthermore, the limiting component includes a push rod, which is slidably connected to a fixed column. A limiting rod is fixedly connected to the outer surface of the push rod, and a sliding ring is fixedly connected to the outer surface of the limiting rod. A spring is fixedly connected to the outer surface of the sliding ring. The push rod, the limiting rod, and the sliding ring are all slidably connected to the rotating column. The limiting rod is used to insert into the fixed column.

[0010] Furthermore, the telescopic assembly includes a screw cylinder, which is rotatably connected to a rotating column. A stud is threadedly connected to the inside of the screw cylinder. A sliding plate is fixedly connected to one end of the stud. A limit block is fixedly connected to the outer surface of the sliding plate. Both the sliding plate and the limit block are slidably connected inside the rotating column. A second wheel frame is fixedly connected to the other end of the stud. A pulley is rotatably connected inside the second wheel frame.

[0011] Furthermore, a lock seat is fixedly connected to the outer surface of the freezer, a sealing plate is rotatably connected to the outer surface of the freezer, and a lock pin is threadedly connected to the outer surface of the sealing plate.

[0012] Furthermore, the outer surface of the screw cylinder is fixedly connected with anti-slip protrusions.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model connects the folding component and the limiting component. When the limiting component is in the initial state, it is inserted into the moving part and the fixed part of the folding component to lock the folding component and prevent unnecessary rotation. When the material rack and the folding component need to be pushed into the freezer, the limiting component is pushed downward to separate the limiting component from the fixed part of the folding component and release the limiting and fixing of the folding component. At this time, the material rack and the folding component are pushed into the freezer. Under the squeezing and guiding action of the supporting component in the freezer, the folding component bends until the entire material rack enters the freezer. There is no need to move the pallets one by one, reducing labor intensity.

[0015] 2. This utility model connects the screw barrel and the stud. When the screw barrel is rotated, the rotation trend of the stud is blocked by the sliding plate and the limiting block. At this time, the screw barrel drives the stud to move the sliding plate and the second wheel frame, which can change the length of the second wheel frame and the pulley extending from the screw barrel, thereby changing the height of the material rack. It can be adjusted as needed.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-7 As shown, this utility model is a freeze-drying device for preparing freeze-dried powder, including a freezer box 1. The freezer box 1 is provided with a support component 2. The top of the support component 2 is provided with a material rack 3. The bottom of the material rack 3 is provided with a folding component 4. The folding component 4 is provided with a limiting component 5 and a telescopic component 6. The support component 2 is used to support the material rack 3. The limiting component 5 is used to lock the folding component 4. The telescopic component 6 is used to adjust the height of the material rack 3.

[0030] The freeze-dried powder raw material is placed on the support component 2 for transfer. When the support component 2 moves to the freezer box 1 through the telescopic component 6, the limiting component 5 is pushed down to release the limiting and fixing of the folding component 4, and the support component 2 is pushed into the interior of the freezer box 1. Under the guidance of the support component 2, the folding component 4 is folded up, and the entire material rack 3 is pushed into the freezer box 1. There is no need to move the trays on the material rack 3 one by one, which is more convenient to use.

[0031] This invention connects the folding component 4 and the limiting component 5. When the limiting component 5 is in its initial state, it is inserted into the movable part and the fixed part of the folding component 4 respectively, thereby locking the folding component 4 and preventing unnecessary rotation. When the material rack 3 and the folding component 4 need to be pushed into the freezer 1, the limiting component 5 is pushed downwards, causing it to separate from the fixed part of the folding component 4 and releasing the limiting and fixing of the folding component 4. At this time, the material rack 3 and the folding component 4 are pushed into the freezer 1. Under the squeezing and guiding action of the supporting component 2 inside the freezer 1, the folding component 4 bends until the entire material rack 3 enters the freezer 1. This eliminates the need to move the pallets one by one, reducing labor intensity.

[0032] In one embodiment, the support assembly 2 includes a fixing plate 201, which is fixedly connected to the inside of the freezer 1. A support column 202 is fixedly connected to the top of the fixing plate 201, and a support plate 203 is fixedly connected to the top of the support column 202. A first wheel frame 204 is fixedly connected to the bottom of the support plate 203, and a guide wheel 205 is rotatably connected inside the first wheel frame 204.

[0033] After the limiting component 5 releases the limiting and fixing of the folding component 4, when the material rack 3 is pushed to drive the folding component 4 into the support plate 203 inside the freezer 1, the guide wheel 205 squeezes the folding component 4, causing the folding component 4 to be folded. At this time, the material rack 3 can be pushed into the freezer 1.

[0034] In one embodiment, the folding assembly 4 includes a fixed post 401, a pin 402 is rotatably connected inside the fixed post 401, and a rotating post 403 is fixedly connected to the end of the pin 402. There are multiple sets of the fixed post 401, the pin 402 and the rotating post 403. The fixed post 401 is fixedly connected to the bottom of the material rack 3.

[0035] In one embodiment, the limiting component 5 includes a push rod 501, which is slidably connected to a fixed post 401. A limiting rod 502 is fixedly connected to the outer surface of the push rod 501. A sliding ring 503 is fixedly connected to the outer surface of the limiting rod 502. A spring 504 is fixedly connected to the outer surface of the sliding ring 503. The push rod 501, the limiting rod 502, and the sliding ring 503 are all slidably connected to the rotating post 403. The limiting rod 502 is used to insert into the fixed post 401.

[0036] Pushing the push rod 501 causes the limiting rod 502 and the sliding ring 503 to slide inside the rotating column 403. The sliding ring 503 compresses the spring 504, and at the same time, the limiting rod 502 separates from the fixed column 401, releasing the limiting fixation between the fixed column 401 and the rotating column 403. At this time, the material rack 3 and the fixed column 401 continue to move. During the movement, the rotating column 403 is squeezed by the guide wheel 205. The guide wheel 205 pushes the rotating column 403 to rotate through the pin 402, causing the rotating column 403 to fold. Continuing to push the material rack 3 can make the material rack 3 and the fixed column 401 slide to the top of the support plate 203.

[0037] In one embodiment, the telescopic component 6 includes a screw cylinder 601 rotatably connected to a rotating column 403. A stud 602 is threadedly connected to the inside of the screw cylinder 601. A sliding plate 603 is fixedly connected to one end of the stud 602. A limiting block 604 is fixedly connected to the outer surface of the sliding plate 603. Both the sliding plate 603 and the limiting block 604 are slidably connected inside the rotating column 403. A second wheel frame 605 is fixedly connected to the other end of the stud 602. A pulley 606 is rotatably connected inside the second wheel frame 605.

[0038] When the screw barrel 601 is rotated, the rotational tendency of the stud 602 inside the screw barrel 601 is blocked by the sliding plate 603 and the limiting block 604. At this time, the screw barrel 601 drives the stud 602 to move the sliding plate 603 and the second wheel frame 605, which can change the length of the second wheel frame 605 and the pulley 606 extending out of the screw barrel 601, thereby changing the height of the material rack 3, which can be adjusted as needed.

[0039] In one embodiment, for the freezer 1, a lock seat 7 is fixedly connected to the outer surface of the freezer 1, a sealing plate 8 is rotatably connected to the outer surface of the freezer 1, and a lock pin 9 is threadedly connected to the outer surface of the sealing plate 8.

[0040] After rotating the sealing plate 8 to fasten it onto the outer surface of the freezer 1, rotate the locking pin 9 on the outer surface of the sealing plate 8 to connect it with the locking seat 7, thus completing the connection and fixation between the sealing plate 8 and the freezer 1, so that the freezer 1 is in a closed state.

[0041] In one embodiment, the outer surface of the screw barrel 601 is fixedly connected with anti-slip protrusions 10.

[0042] The anti-slip protrusions 10 make the outer surface of the screw barrel 601 uneven, which increases the friction when rotating the screw barrel 601 and prevents slippage.

[0043] Through the above technical solution, 1. By connecting the folding component 4 and the limiting component 5, when the limiting component 5 is in the initial state, it is inserted into the moving part and the fixed part of the folding component 4 respectively, thereby locking the folding component 4 and preventing unnecessary rotation of the folding component 4. When it is necessary to push the material rack 3 and the folding component 4 into the freezer 1, the limiting component 5 is pushed downwards, causing the limiting component 5 to separate from the fixed part of the folding component 4, releasing the limiting fixation of the folding component 4. At this time, the material rack 3 and the folding component 4 are continued to be pushed into the freezer 1. 1. Under the squeezing and guiding action of the supporting component 2, the folding component 4 bends until the entire material rack 3 enters the freezer 1, eliminating the need to handle each pallet individually and reducing labor intensity; 2. Through the connection between the screw barrel 601 and the stud 602, when the screw barrel 601 is rotated, the rotation trend of the stud 602 is blocked by the sliding plate 603 and the limiting block 604. At this time, the screw barrel 601 drives the stud 602 to move the sliding plate 603 and the second wheel frame 605, which can change the length of the second wheel frame 605 and the pulley 606 extending from the screw barrel 601, thereby changing the height of the material rack 3, which can be adjusted as needed.
