Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a freeze-drying tray cleaning device. Background Technology

[0002] Freeze-drying (FDR) technology, as an important process for dehydrating and preserving materials, has been widely used in fields such as biopharmaceuticals, food processing, and medical products. The freeze dryer is the core equipment of this process. It has multiple layers of freeze-drying trays installed inside to hold the materials. After the materials are freeze-dried, because the materials are placed directly on the freeze-drying trays, material debris and impurities will remain on the freeze-drying trays. If the freeze-drying trays are not thoroughly cleaned, it will not only affect the processing quality of the next batch of materials, but also reduce the heat transfer efficiency of the freeze-drying trays.

[0003] Traditional freeze-drying tray cleaning methods mainly rely on manual labor, which has the following drawbacks: 1. Freeze-drying trays are large in size and numerous, and manual cleaning of freeze-drying trays takes a long time, resulting in long equipment downtime and affecting production efficiency; 2. The quality of manual cleaning depends on the operator's experience, causing fluctuations in the cleanliness of the freeze-drying trays and making it easy for the cleanliness of the freeze-drying trays to fail to meet standards; 3. Depending on the materials being processed, some freeze-drying trays require the use of corrosive cleaning agents, posing a safety hazard of chemical burns to operators.

[0004] To solve the above-mentioned technical problems, the technical solution of the Chinese utility model patent announcement with patent application number CN202121993630.5 is a freeze-drying tray cleaning device for freeze-dried strawberries, including a cleaning frame, support blocks, a sliding groove, a slider, a sliding support plate, a lower fixed frame, a spring, a fixed pressure plate, a vertical support plate, a diffusion nozzle, a mounting cavity, a micro vibrator, a cleaning brush, an upper pressure plate, a lower moving guide hole, an upper moving guide hole, a transverse support plate, and an electric telescopic rod. The lower telescopic end of the electric telescopic rod is connected to the vertical support plate. The end of the vertical support plate away from the cleaning brush is provided with a water guide pipe connected to the diffusion nozzle. The upper end of the transverse support plate is provided with a water tank. Three evenly distributed high-pressure submersible pumps are provided on the bottom surface inside the water tank. The upper end of the water guide pipe extends into the water tank and is connected to the high-pressure submersible pumps. A wastewater collection tank is provided on the lower part of the outside of the cleaning frame. Water guide holes are provided on the bottom surface of the cleaning frame between the support blocks.

[0005] However, the above-mentioned prior art has the following technical problems: every time a freeze-dried product is processed by a freeze dryer, a large number of freeze-drying trays that need to be cleaned are generated. When the freeze-drying tray cleaning device for freeze-dried strawberries is used to clean the freeze-drying trays, each set of freeze-drying trays needs to undergo all the cleaning processes before the next set of freeze-drying trays can be cleaned, which makes the overall cleaning cycle of the freeze-drying trays long and difficult to meet the freeze-drying tray cleaning needs of enterprises.

The first bevel gear meshes with the second bevel gear so that the first bevel gear can rotate along the circumference of the second bevel gear, thereby driving the corresponding hoisting rod to rotate around the fixed rod as the center through the first drive motor.

[0013] Preferably, the freeze-drying tray cleaning device further includes a water circulation component, which includes a circulation pump, a filter, a heating element, and a water storage tank. The input end of the circulation pump is connected to the outlet water pipe of the rinsing component, and the output end is connected to the inlet water pipe of the water storage tank to send the rinsing water of the rinsing component to the water storage tank. The filter and the heating element are installed on the pipeline between the circulation pump and the water storage tank. The filter is used to filter the rinsing water, and the heating element is used to heat the rinsing water. The outlet end of the water storage tank is connected to the inlet end of the pre-washing component to send the hot water in the water storage tank to the pre-washing component.

The bottom end of the fixing component is fixedly connected to the ground, and the transfer assembly is rotatably mounted on the top of the fixing component. The transfer assembly has at least four lifting ends, each used to mount a storage component. When the transfer assembly rotates around the fixing component, each lifting end sequentially sends a storage component to the pre-washing component, rinsing component, and drying component. The pre-washing component pre-washes the freeze-drying trays in the storage components, the rinsing component rinses the freeze-drying trays in the storage components, and the drying component dries the freeze-drying trays in the storage components, thereby cleaning the freeze-drying trays in the storage components. Cleaning is performed by placing the freeze-drying trays into their respective storage components. These components are then sequentially mounted onto the hoisting end, which is about to transfer to the pre-washing component. As the transfer assembly rotates, the hoisting end sequentially sends the storage components to the pre-washing, rinsing, and drying components for cleaning. The cleaned storage components are then removed from the hoisting end. During this process, different stages of cleaning can be performed simultaneously on the freeze-drying trays in the three storage components. For example, while the first group of trays is drying in the drying component, the second group is rinsing in the rinsing component, and the third group is pre-washing in the pre-washing component. This continuous cleaning of the freeze-drying trays in each storage component, achieved through the rotation of the hoisting end, shortens the overall cleaning cycle and meets the enterprise's freeze-drying tray cleaning needs.

Detailed Implementation

[0032] The technical solutions and effects of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0033] Please refer to Figure 1This utility model provides a freeze-drying tray cleaning device 10, including a pre-washing component 20, a rinsing component 30, a drying component 40, a transfer component 50, and at least four identical storage components 60. The pre-washing component 20, rinsing component 30, and drying component 40 are arranged sequentially around the transfer component 50. The pre-washing component 20 is used to pre-wash the freeze-drying trays 80, the rinsing component 30 is used to rinse the freeze-drying trays 80, and the drying component 40 is used to dry the freeze-drying trays 80. Each storage component 60 is used to hold at least two freeze-drying trays 80. The transfer component 50 includes a fixing component 51 and a transfer component 52. The bottom end of the fixing component 51 is fixedly connected to the ground, and the transfer component 52 is rotatably mounted on the top end of the fixing component 51. The transfer component 52 is provided with at least four lifting ends, each of which is used to install the storage components 60, so that as the transfer component 52 rotates, each storage component 60 is sequentially fed into the pre-washing component 20, the rinsing component 30, and the drying component 40 for corresponding cleaning. Operation: Thus, when cleaning the freeze-drying trays 80, the freeze-drying trays 80 to be cleaned are first placed in the respective storage components 60. Then, each storage component 60 is installed on the hoisting end that is about to be transferred to the pre-washing component 20. Afterward, as the transfer assembly 52 rotates, each hoisting end sequentially sends the storage components 60 to the pre-washing component 20, the rinsing component 30, and the drying component 40 to clean the freeze-drying trays 80 in the storage components 60. Then, the cleaned storage components 60 are removed from the hoisting end. During the process, the freeze-drying trays 80 in the three storage components 60 can be cleaned at different stages simultaneously. For example, while the first group of freeze-drying trays is being dried in the drying component 40, the second group of freeze-drying trays is being rinsed in the rinsing component 30, and the third group of freeze-drying trays is being pre-washed in the pre-washing component 20. This allows the freeze-drying trays 80 in the storage components 60 to be cleaned continuously as each hoisting end rotates, thereby shortening the overall cleaning cycle of the freeze-drying trays 80 and meeting the enterprise's freeze-drying trays 80 cleaning needs.

[0034] Please refer to Figures 2 to 3 Furthermore, each storage component 60 includes a lifting rod 61, at least two connecting rods 62, and a storage rack 63. The lifting rod 61 is used to connect to each lifting end of the transfer component 52. One end of each connecting rod 62 is connected to the bottom surface of the lifting rod 61, and the other end is connected to the storage rack 63 to fix the storage rack 63 to the bottom surface of the lifting rod 61. The storage rack 63 has at least two layers of vertical storage structure for placing freeze-drying trays 80. Specifically, the number of vertical storage structures can be increased according to the needs of the enterprise and the size of the factory to increase the number of freeze-drying trays 80 that the storage component 60 can hold.

[0035] Please refer to Figure 4Furthermore, the fixing component 51 includes a fixing base 511 and a fixing rod 512. The fixing base 511 is fixedly connected to the ground, and the bottom end of the fixing rod 512 is fixedly connected to the fixing base 511.

[0036] Please refer to Figure 5 Furthermore, the transfer assembly 52 includes a transfer ring 521 and at least four identical hoisting groups 522. The transfer ring 521 is rotatably mounted on the fixed rod 512. Each hoisting group 522 is evenly mounted on the transfer ring 521 along its circumference. Each hoisting group 522 includes a hoisting rod 5221, a telescopic member 5222, a hoisting frame 5223, and at least two hooks 5224. One end of the hoisting rod 5221 is fixedly connected to the transfer ring 521. The fixed end of the telescopic member 5222 is fixedly mounted on the other end of the hoisting rod 5221. The top end of the hoisting frame 5223 is fixedly connected to the telescopic end of the telescopic member 5222. Each hook 5224 is evenly mounted on the bottom end of the hoisting frame 5223 for clamping the hoisting frame. Thus, each hoisting group 522 can rotate around the fixed rod 512 to sequentially send each storage component to the pre-washing component 20, the rinsing component 30, and the drying component 40.

[0037] Please refer to Figure 2 , Figure 3 and Figure 6 Furthermore, the lifting rod 61 is a triangular prism arranged horizontally with its pointed end facing upwards; each hook 5224 includes two identical clamping hooks 52241, one end of which is rotatably mounted on the lifting frame 5223, and the other end is semi-circular with the flat end of the semi-circular end facing the lifting frame 5223. Thus, when the lifting rod 61 is gripped by the hook 5224, the hook 5224 gradually lowers in height, and when the bottom of the hook 5224 contacts the top of the lifting rod 61, The arc-shaped surfaces of the semi-circular ends of the two hooks 52241 move outward along the inclined surfaces on both sides of the lifting rod 61, opening the hook component 5224. When the planes of the semi-circular ends of the two hooks 52241 move to the plane at the bottom of the lifting rod 61, the two hooks 52241 move inward toward the lifting rod 61, closing the hook component 5224, so as to engage the planes of the semi-circular ends of the two hooks 52241 with the plane at the bottom of the lifting rod 61, thereby fixing the hook component 5224 to the lifting rod 61.

[0038] Please refer to Figure 5In this embodiment, the transfer assembly 52 further includes a first drive motor 523. The fixed end of the drive motor is mounted on any of the hoisting rods 5221. The drive end of the drive motor is arranged in a horizontal direction and is equipped with a first bevel gear 524. The top of the fixed rod 512 is provided with a second bevel gear 513 in a vertical direction. The first bevel gear 524 meshes with the second bevel gear 513 so that the first bevel gear 524 can rotate along the circumference of the second bevel gear 513. Thus, the first drive motor 523 drives any of the hoisting rods 5221 to rotate around the fixed rod 512. In this way, the first drive motor 523 drives the hoisting rod 5221 to rotate around the fixed rod 512, thereby driving the transfer ring 521 to rotate around the fixed rod 512.

[0039] Please refer to Figure 7 Furthermore, the freeze-drying tray cleaning device 10 also includes a water circulation component 70, which includes a circulation pump 71, a filter element 72, a heating element 73, and a water storage tank 74. The input end of the circulation pump 71 is connected to the outlet water pipe of the rinsing component 30, and the output end is connected to the inlet water pipe of the water storage tank 74 to send the rinsing water of the rinsing component 30 to the water storage tank 74. The filter element 72 and the heating element 73 are installed on the pipeline between the circulation pump 71 and the water storage tank 74. The filter element 72 is used to filter the rinsing water, and the heating element 73 is used to heat the rinsing water. The outlet end of the water storage tank 74 is connected to the inlet end of the pre-washing component 20 to send the hot water in the water storage tank 74 to the pre-washing component 20. The water storage tank 74 is also equipped with a first temperature sensor 75 for detecting the water temperature inside the water storage tank 74; the water storage tank 74 is also equipped with a water supply pipe for replenishing hot water into the water storage tank 74. Specifically, the filter element 72 is a double filter tank, and the heating element 73 is a plate heat exchanger; in this way, the rinsing water of the rinsing component 30 can be sent to the water storage tank 74 by the circulating pump 71. In this process, the rinsing water flows through the filter element 72 and the heating element 73 in sequence. The filter element 72 filters out impurities in the rinsing water, and the heating element 73 heats the temperature of the rinsing water to the temperature required by the pre-washing component 20, thereby recycling the rinsing water, improving the utilization rate of water resources, and reducing the cleaning cost of the freeze-drying tray 80.

[0040] Please refer to Figures 8 to 9Furthermore, the pre-wash component 20 includes a first washing tank 21, two impellers 22, two drive rods 23, a second drive motor 24, two driven pulleys 25, and two drive pulleys 26. The outlet end of the first washing tank 21 is connected to the inlet end of the rinsing component 30 via a water pipe to deliver pre-wash water to the rinsing component 30. The two impellers 22 are rotatably mounted on the bottom surface of the first washing tank 21. The top ends of the two drive rods 23 are fixedly connected to the bottom ends of the two impellers 22, respectively. The two driven pulleys 25 are fixedly mounted on the bottom ends of the two drive rods 23, respectively. The drive shaft of the second drive motor 24 is rotatably mounted on the bottom end of the first washing tank 21, and the two drive pulleys 26 are both fixedly mounted on... On the drive shaft of the second drive motor 24, two drive pulleys 26 are respectively connected to two driven pulleys 25 for transmission, so as to drive two drive rods 23 to rotate through the drive shaft of the second drive motor 24, thereby driving two impellers 22 to rotate; a second temperature sensor 27 is also provided on the first cleaning tank 21 for detecting the water temperature in the first cleaning tank 21; a drain pipe 28 is also provided on the first cleaning tank 21 for draining water outward; thus, when pre-washing the freeze-drying tray 80, the second drive motor 24 drives the two impellers 22 to rotate, stirring the hot water in the first cleaning tank 21, so that the hot water forms a small vortex in the first cleaning tank 21, so as to remove dirt from the surface of the freeze-drying tray 80 as the hot water rotates.

[0041] In this embodiment, the pre-washing process is as follows:

[0042] 1. The telescopic component 5222 lowers the hook component 5224 to send the storage component 60 into the first cleaning tank 21;

[0043] 2. The water storage tank 74 delivers hot water into the first cleaning tank 21;

[0044] 3. The second drive motor 24 drives the two impellers 22 to rotate, stirring the hot water in the first cleaning tank 21 to boil and wash the freeze-drying tray 80;

[0045] 4. After the first predetermined time has elapsed, the drain pipe 28 will drain the water from the first cleaning tank 21;

[0046] 5. The second drive motor 24 stops rotating and sends hot water into the first cleaning tank 21 through the water storage tank 74;

[0047] 6. After waiting for the second predetermined time, the telescopic component 5222 raises the hook component 5224 to send the storage component 60 out of the first cleaning tank 21, completing the soaking and washing of the freeze-drying tray 80.

[0048] Please refer to Figures 10 to 11Furthermore, the rinsing component 30 includes a pressurizing pump 31, a second cleaning tank 32, and at least two rinsing elements 33. The pressurizing pump 31 is installed on the pipeline between the first cleaning tank 21 and the second cleaning tank 32 to pressurize the pre-wash water and send it to the second cleaning tank 32. Each rinsing element 33 is evenly arranged on both sides of the second cleaning tank 32, and each rinsing element 33 is evenly provided with at least two rinsing nozzles 34 to spray the pressurized pre-wash water onto the freeze-drying tray 80. Thus, the pressurizing pump 31 sends the pre-wash water discharged from the pre-washing component 20 to the second cleaning tank 32, and then the rinsing nozzles 34 spray the pressurized pre-wash water onto the freeze-drying tray 80 to rinse away the sticky dirt on the freeze-drying tray 80.

[0049] Please refer to Figures 12 to 13 Furthermore, the drying component 40 includes a third cleaning tank 41, an air pump 42, and at least two blowers 43. The air inlet of the air pump 42 is connected to a sterile gas generating device, and the air outlet is connected to the third cleaning tank 41 to deliver sterile gas to the third cleaning tank 41. Each blower 43 is evenly arranged on both sides of the third cleaning tank 41 to blow sterile gas, such as sterile air, onto the freeze-drying tray 80. Thus, sterile gas is delivered to the third cleaning tank 41 by the air pump 42 and sprayed onto the freeze-drying tray 80 from each blower 43 to dry the surface of the freeze-drying tray 80, thereby completing the cleaning of each freeze-drying tray 80.

[0050] In this embodiment, the sterile gas generating device or air pump 42 is equipped with a heating device to heat the sterile gas and accelerate the drying speed of the freeze-drying tray 80.
