Description

Technical Field

[0001] The present invention relates to the technical field of freeze-drying tray processing, and particularly to a large-scale mobile cleaning, sterilization and drying system. Background Art

[0002] Vacuum freeze-drying, abbreviated as freeze-drying, is a drying method in which an object is frozen below the eutectic point temperature and then the moisture in the object is removed by sublimation drying under a relatively high vacuum condition. The freeze-dried powder obtained by this method has the advantages of being able to well maintain the original activity of the object, maintaining the color of the object, and being convenient for long-term storage. Therefore, the freeze-drying technology is widely used in the fields of food, medicine, biology, agriculture, etc.

[0003] Freeze-drying trays are essential loading utensils in the freeze-drying process. At present, the freeze-drying trays seen on the market are mainly of two types: stainless steel freeze-drying trays and disposable sterile freeze-drying trays. Using disposable sterile freeze-drying trays can reduce the risk of cross-contamination and ensure the quality of freeze-dried powder. However, disposable products will cause problems such as waste of resources, difficult recycling, high recycling costs, and environmental pollution. While using stainless steel freeze-drying trays requires cleaning, sterilization, drying, transfer, storage, etc., the process is complex and the possibility of cross-contamination is high. In addition, during the cleaning process, the current cleaning method for stainless steel freeze-drying trays is mainly manual cleaning, which has defects such as uncontrollability, difficulty in ensuring cleaning quality, large labor intensity, low cleaning efficiency, and high labor costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a large-scale mobile cleaning, sterilization and drying system that can perform large-batch cleaning, sterilization and drying on freeze-drying trays with good cleaning, sterilization and drying effects and high cleaning, sterilization and drying efficiency. With this system, cleaning, sterilization and drying are all carried out in the same sterilization cabinet, avoiding the pollution risk brought by transfer.

[0005] At present, the method for cleaning used stainless steel freeze-drying trays is to clean them by manual cleaning, and then transfer them to the sterilization cabinet for sterilization and drying. Due to the defects of manual cleaning such as uncontrollability, difficulty in ensuring cleaning quality, large labor intensity, low cleaning efficiency, and high labor costs, in view of this situation, the present invention designs a large-scale mobile cleaning, sterilization and drying system, designs a set of pipeline systems for cleaning and sterilization requirements, introduces clean steam, industrial steam, and cold pure water, heats the cold pure water with industrial steam, and introduces industrial steam supplemented by jacket auxiliary heating to ensure the temperature of the cleaning water and improve the cleaning quality.

A branch industrial steam inlet pipe is communicated with the industrial steam inlet pipe. A second branch valve is installed on the branch industrial steam inlet pipe; The branch industrial steam inlet pipe is communicated with the first inlet of the first heat exchange channel. The first outlet of the first heat exchange channel is connected with a branch condensate drain pipe. A first steam trap and a first check valve are installed on the branch condensate drain pipe; One end of the cold pure water inlet pipe is the cold pure water inlet end for accessing cold pure water. The other end of the cold pure water inlet pipe is communicated with the second inlet of the second heat exchange channel. A fourth valve is installed on the cold pure water inlet pipe. The second outlet of the second heat exchange channel is communicated with the water inlet of the water storage tank through a water inlet pipe. A cleaning agent quick connector is connected to the water inlet pipe. The water outlet pipe at the bottom of the water storage tank is respectively communicated with a first branch water outlet pipe and a second branch water outlet pipe. The first branch water outlet pipe is connected to the sewage drain pipe. A third branch valve and a second check valve are installed on the first branch water outlet pipe. The second branch water outlet pipe is communicated with the inlet of the centrifugal pump. A fourth branch valve is installed on the second branch water outlet pipe. One end of the second pipeline is communicated with the outlet of the centrifugal pump. The other end of the second pipeline is converged with the cold pure water inlet pipe and then communicated with the second inlet of the second heat exchange channel. A fifth valve is installed on the second pipeline. The sewage discharge port of the centrifugal pump is connected to the sewage drain pipe through a branch sewage drain pipe.

[0009] A spray cleaning method for a large-scale mobile cleaning, sterilization, and drying system is as follows: (1)Hot water preparation in the water storage tank: Cold pure water is introduced through the cold pure water access end. The cold pure water enters the second heat exchange channel in the heat exchanger through the cold pure water inlet pipe, and indirectly exchanges heat with the industrial steam in the first heat exchange channel of the heat exchanger. After absorbing heat, it enters the water storage tank through the water inlet pipe. The cleaning agent is put into the water storage tank through the cleaning agent quick connector. If the hot water temperature in the water storage tank does not reach the required set temperature, the hot water in the water storage tank is pumped by the centrifugal pump and returns to the second heat exchange channel in the heat exchanger through the second branch outlet pipe and the second pipeline, and continues to indirectly exchange heat with the industrial steam in the first heat exchange channel of the heat exchanger. After absorbing heat, it enters the water storage tank through the water inlet pipe. Repeat the above steps until the hot water temperature in the water storage tank reaches the required set temperature; (2)Spray cleaning: The hot water in the water storage tank is pumped by the centrifugal pump and enters each spray device through the spray medium inlet pipe and each branch spray medium inlet pipe. All products to be processed in the sterilization chamber are spray-cleaned through each spray device. During the set time of spray cleaning, the water after spray cleaning in the sterilization chamber does not meet the requirements for recycling, and the water after spray cleaning in the sterilization chamber is discharged through the sewage drain pipe. After the set time of spray cleaning, the water after spray cleaning in the sterilization chamber meets the requirements for recycling. The water after spray cleaning is collected with the hot water flowing out of the water storage tank through the first pipeline and the first collecting pipe and then re-introduced into the spray device. During this process, the conductivity meter installed on the first connecting pipe is used for real-time monitoring to monitor the cleanliness of the water after spray cleaning in real time. During the spray cleaning process, jacket-assisted heating is supplemented. Industrial steam is introduced through the industrial steam access end. The industrial steam enters the hollow interlayer of the sterilization cabinet through the industrial steam inlet pipe to assist in heating the spray cleaning.

[0010] Further, in the above-mentioned large-scale mobile cleaning, sterilization and drying system, a first branch pipeline is connected to the clean steam inlet pipe. The first branch pipeline is connected to the spray medium inlet pipe, and a seventh branch valve is installed on the first branch pipeline. After all products to be processed in the sterilization chamber are spray-cleaned, sterilization treatment is carried out. Clean steam is introduced through the clean steam access end. The clean steam is divided into two paths: one path passes through the clean steam inlet pipe, each branch clean steam inlet pipe, and each rotating cleaning ball and is sprayed onto all products to be processed in the sterilization chamber; the other path passes through the first branch pipeline, each branch spray medium inlet pipe, and each spray device and is sprayed onto all products to be processed in the sterilization chamber. All products to be processed in the sterilization chamber are sterilized by the two paths of clean steam.

[0011] A second branch pipeline is connected to the spray medium inlet pipe. The second branch pipeline is connected to the condensate drain pipe, and an eighth branch valve, a third steam trap and a fifth check valve are installed on the second branch pipeline. The condensate generated during the sterilization process is discharged through the second branch pipeline and the condensate drain pipe.

[0012] Furthermore, in the aforementioned large mobile cleaning, sterilizing and drying system, a sampling pipe is connected to the second branch outlet water pipe; A recovery pipe is connected to the bottom outlet of the sterilization chamber, and a tenth valve is installed on the recovery pipe; A relief port is provided on the sterilization chamber of the sterilization cabinet, a relief pipe is connected to the relief port, and a relief valve is installed on the relief pipe; The tank body of the water storage tank is a heat-insulating jacket structure with a vacuum interlayer.

[0013] When this system is applied to cleaning, sterilizing and drying freeze-dried trays, a spraying device suitable for cleaning and sterilizing freeze-dried trays is designed for the freeze-dried trays. The structure of the spraying device in this solution includes: a spraying frame, which is composed of a bottom bracket and a left mounting frame arranged on the left side of the bottom bracket; a traveling mechanism capable of traveling on the track group at the bottom of the sterilization chamber is arranged at the bottom of the bottom bracket; several groups of bottom spraying groups are arranged at intervals from top to bottom on the left mounting frame, and each group of bottom spraying groups is composed of several horizontal spraying pipes arranged at intervals from front to back. Several first spray heads spraying upward are installed at intervals from left to right on the pipe wall of each horizontal spraying pipe; a vertical spraying pipe is arranged on the right side of the bottom bracket, and several second spray heads spraying leftward are installed at intervals from top to bottom on the pipe wall of the vertical spraying pipe; the vertical spraying pipe and each horizontal spraying pipe are connected to a hose through a water passage on the spraying frame, and the hose is communicated with the outlet of the corresponding branch spraying medium inlet pipe; Each rotating cleaning ball is located above each spraying device, and each spraying device is driven by a driving structure to move forward or backward synchronously in the same direction on the track group; The aforementioned large mobile cleaning, sterilizing and drying system is equipped with several hanging trolleys. A hoisting beam horizontally placed from front to back is hung at the top inside the sterilization chamber; the hanging trolley includes: a hanging vehicle frame, which is composed of a bottom vehicle frame, a right vehicle frame arranged on the right side of the bottom vehicle frame, and a top vehicle frame arranged on the top of the right vehicle frame. A sliding mechanism capable of hanging on the hoisting beam and sliding along the axis direction of the hoisting beam under the action of an external force is arranged on the top of the top vehicle frame; the space between the bottom vehicle frame, the right vehicle frame and the top vehicle frame is a placement space for placing products to be processed. Several groups of shelving groups are arranged at intervals from top to bottom on the right vehicle frame, and each shelving group is located in the placement space. At least one product to be processed is placed at least from front to back on each shelving group; when the hanging trolley enters any spraying device, a group of shelving groups enters the space between two adjacent bottom spraying groups, the right vehicle frame enters the space between the vertical spraying pipe and each group of bottom spraying groups, and there are holes on the right vehicle frame for the spraying medium sprayed by each second spray head to pass through. The bottom vehicle frame enters the space between the bottommost bottom spraying group and the bottom bracket.

[0014] Since the spraying device moves back and forth, in order to ensure that the spraying device can move back and forth, the hose has a certain length. To facilitate the management of the hose, a spring is provided in the sterilization chamber in this solution. Each hose corresponds to at least one spring. One end of the spring is fixed to the inner wall of the sterilization chamber, and the other end of the spring is fixed to the corresponding hose.

[0015] For the driving structure that drives the spraying device to move back and forth, considering the application scenario of the sterilization cabinet, the driving structure is designed here as follows: the spraying devices are arranged at intervals in sequence from front to back, and each spraying device is connected by a total connecting frame; A first connecting block is hermetically and fixedly installed in the through hole at the rear of the sterilization cabinet. The front end of the first connecting block is located inside the sterilization chamber, and the rear end of the first connecting block is located outside the sterilization cabinet. A channel penetrating through from front to back is opened in the first connecting block; The push rod is hermetically inserted into the channel. The front end of the push rod is fixedly connected to the total connecting frame. An internal threaded channel is opened inward at the rear end of the push rod.

The rear end of the screw rod extending out of the internal threaded channel is fixedly connected to the output shaft of the reduction motor. The reduction motor is fixed on the platform outside the sterilization cabinet, and the push rod is circumferentially limited by a guiding structure, so that when the screw rod rotates forward or backward, it can only force the push rod to move forward or backward; A corrugated pipe is sleeved on the push rod located inside the sterilization chamber. A second connecting block is fixedly arranged on the front section of the push rod. The front end of the corrugated pipe is hermetically and fixedly connected to the second connecting block, and the rear end of the corrugated pipe is hermetically and fixedly connected to the first connecting block.

[0016] Further, in the aforementioned large-scale mobile cleaning, sterilization and drying system, an installation block is arranged on the rear end of the total connecting frame. A hemispherical positioning hole is opened inward on the rear end face of the installation block. The head of the push rod from front to back is in sequence: a hemisphere matching the hemispherical positioning hole, a connecting shaft with a diameter smaller than the diameter of the hemisphere. After the limiting piece is stuck on the connecting shaft, it is fixedly connected to the installation block, so as to limit the hemisphere in the hemispherical positioning hole.

[0017] Further, in the aforementioned large-scale mobile cleaning, sterilization and drying system, the sliding mechanism is as follows: a sliding seat is arranged on the top of the top frame. A sliding groove is arranged downward on the top of the sliding seat. At least two left rollers are arranged on the left side of the sliding groove, and at least two right rollers are arranged on the right side of the sliding groove. A space for the hoisting beam to penetrate is formed among each left roller, each right roller and the sliding groove; when the suspended trolley is suspended on the hoisting beam, each left roller and each right roller rollingly contact with the upper semi-circular arc surface of the hoisting beam, and the hoisting beam does not contact the sliding groove.

[0018] Furthermore, in the aforementioned large-scale mobile cleaning, sterilization and drying system, a counterweight is provided on the right frame; the top surface of the top frame is an inclined surface.

Therefore, it can carry out cleaning, sterilization and drying on a large number of products to be processed, and the cleaning, sterilization and drying are all carried out in the same sterilization cabinet, avoiding the pollution risk caused by transfer. The cleaning, sterilization and drying effects are good, and the cleaning, sterilization and drying efficiency is high. It is especially suitable for the cleaning, sterilization and drying treatment of freeze-dried trays, so as to achieve the purpose that the freeze-dried trays will not contaminate each batch of freeze-dried products during the recycling process; ② Through the structural design of the spraying device and the hanging trolley, supplemented by the rotating cleaning ball, multi-angle and multi-directional spraying and rinsing sterilization are realized, and there are basically no dead corners in the cleaning and sterilization, greatly improving the cleanliness after cleaning and sterilization, and ensuring that the used freeze-dried trays reach the required cleanliness after being cleaned, sterilized and dried by the large-scale mobile cleaning, sterilization and drying system described in the present invention.

[0048] A more preferred solution is to connect a sampling pipe 542 to the second branch outlet pipe 54.

[0049] A more preferred solution is that the tank body of the water storage tank 400 is a heat-insulating jacket structure with a vacuum interlayer.

[0050] The inlet of each spraying device 300 is connected to a branch spraying medium inlet pipe 56. A sixth branch valve 561 is installed on each branch spraying medium inlet pipe 56. One end of the spraying medium inlet pipe 55 is connected to the second pipeline 52. The other end of the spraying medium inlet pipe 55 is respectively connected to the inlets of each branch spraying medium inlet pipe 56. A sixth valve 551 is installed on the spraying medium inlet pipe 55.

[0051] Such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, the structure of the fifth pipeline system in this embodiment is as follows: One end of the interlayer discharge pipe 2 is connected to the interlayer outlet of the hollow interlayer 1004, and the other end of the interlayer discharge pipe 2 is respectively connected to the condensate drain pipe 21 and the inlet of the third pipeline 22. A second steam trap 201 is installed on the interlayer discharge pipe 2, and a third check valve 211 is installed on the condensate drain pipe 21. The branch condensate drain pipe 23 in the fourth pipeline system is connected to the condensate drain pipe 21; A fourth check valve 221, a vacuum pump 222, and a seventh valve 223 are installed on the third pipeline 22. After the third pipeline 22 and the first pipeline 12 in the third pipeline system converge, they are connected to the second branch water outlet pipe 54 through a first collecting pipe 24, and an eighth valve 241 is installed on the first collecting pipe 24; One end of the cooling pipe 57 is connected to the cold pure water inlet pipe 5 in the fourth pipeline system, and the other end of the cooling pipe 57 is connected to the cooling port of the vacuum pump 222. A ninth valve 571 is installed on the cooling pipe 57.

[0052] A more preferred solution is that a first branch pipeline 32 is connected to the clean steam inlet pipe 3, the first branch pipeline 32 is connected to the spray medium inlet pipe 55, and a seventh branch valve 321 is installed on the first branch pipeline 32; A second branch pipeline 58 is connected to the spray medium inlet pipe 55, the second branch pipeline 58 is connected to the condensate drain pipe 21, and an eighth branch valve 581, a third steam trap 582, and a fifth check valve 583 are installed on the second branch pipeline 58.

[0053] The working principles of the pipeline systems in the above-mentioned large-scale mobile cleaning, sterilization, and drying system are as follows: Cold pure water is connected through the cold pure water access end 501. The cold pure water enters the second heat exchange channel in the heat exchanger 500 through the cold pure water inlet pipe 5, and indirectly exchanges heat with the industrial steam entering the first heat exchange channel in the heat exchanger 500. After absorbing heat, it enters the water storage tank 400 through the water inlet pipe 51. The cleaning agent can be put into the water storage tank 400 through the cleaning agent quick interface 511. If the hot water temperature in the water storage tank 400 has not reached the required set temperature at this time, then the hot water in the water storage tank 400 is pumped by the centrifugal pump 600 and returns to the second heat exchange channel in the heat exchanger 500 through the second branch water outlet pipe 54 and the second pipeline 52, and continues to indirectly exchange heat with the industrial steam entering the first heat exchange channel in the heat exchanger 500. After absorbing heat, it enters the water storage tank 400 through the water inlet pipe 51, and repeats the above steps until the hot water temperature in the water storage tank 400 reaches the required set temperature. If the hot water temperature in the water storage tank 400 has reached the temperature required for cleaning at this time, then when spraying is required, the hot water in the water storage tank 400 can be sent to the spraying device 300.

[0054] During the process of filling the water storage tank 400 with water or circulating and heating the water in the water storage tank 400, a cleaning agent is added through the cleaning agent quick connector 511. A conductivity meter 4001 for the water storage tank, which is used to detect the content of the cleaning agent in the water storage tank 400, is provided on the water storage tank 400.

[0055] When the hot water in the water storage tank 400 flows to the spraying device 300, the hot water in the water storage tank 400 is pumped by the centrifugal pump 600 and enters each spraying device 300 through the spraying medium inlet pipe 55 and each branch spraying medium inlet pipe 56. All the products to be processed in the sterilization chamber 1001 are spray-cleaned through each spraying device 300. During the process of spray-cleaning the products to be processed, for example, within half an hour after the start of spray-cleaning (this time is only for example and does not limit the spray-cleaning time), the cleanliness of the water after spray-cleaning during this period does not meet the requirement for recycling, so it is discharged through the sewage drain pipe 11. After half an hour of spray-cleaning, the cleanliness of the water after subsequent spray-cleaning can meet the requirement for recycling, so it is collected with the hot water flowing out of the water storage tank 400 through the first pipeline 12 and the first collecting pipe 24 and then re-introduced into the spraying device 300. During this process, real-time monitoring can be carried out through the conductivity meter 122 installed on the first connecting pipe 12 to monitor the cleanliness of the water after spray-cleaning in real time. In order to prevent the circulating hot water from getting cold during the circulating cleaning process and not reaching the required cleaning temperature, jacket-assisted heating is supplemented. Industrial steam is introduced through the industrial steam access end 401, and the industrial steam enters the hollow interlayer 1004 of the sterilization cabinet 100 through the industrial steam inlet pipe 4 to achieve the purpose of jacket-assisted heating.

[0056] During the process of spray-cleaning, clean steam is introduced through the clean steam access end 301. The clean steam enters all the products to be processed in the sterilization chamber 1001 through the clean steam inlet pipe 3, each branch clean steam inlet pipe 31, and each rotating cleaning ball 200. By opening the seventh branch valve 321, the clean steam can also be sprayed onto all the products to be processed in the sterilization chamber through the first branch pipeline 32, each branch spraying medium inlet pipe 56, and each spraying device 300. All the products to be processed in the sterilization chamber 1001 are sterilized by the two-way clean steam. In addition, during the process of spray-cleaning, if the hot water temperature is high enough to reach the sterilization temperature, then there is also a sterilization effect during the process of spray-cleaning.

[0057] After the cleaning and sterilization process is completed, drying treatment is carried out. The drying treatment is the same as the drying treatment method of the previous sterilization cabinet, so the drying treatment will not be elaborated here. This belongs to the mature technology of the sterilization cabinet.

[0058] By adopting the above-mentioned large-scale mobile cleaning, sterilization and drying system, a large number of products to be processed can be accommodated in the sterilization chamber 1001. Therefore, cleaning, sterilization and drying can be carried out for a large number of products to be processed, and cleaning, sterilization and drying are all carried out in the same sterilization cabinet, avoiding the pollution risk caused by transfer. The cleaning, sterilization and drying effects are good, and the cleaning, sterilization and drying efficiency is high. It is especially suitable for the cleaning, sterilization and drying treatment of freeze-dried trays, so as to achieve the purpose that the freeze-dried trays will not contaminate each batch of freeze-dried products during the recycling process. Embodiment 2

[0059] In this embodiment, a spraying device capable of cleaning and sterilizing freeze-dried trays is designed. The structure of each spraying device 300 is the same. As Figure 4 and Figure 5 shown, the structure of the spraying device 300 in this embodiment includes: a spraying frame, which is composed of a bottom bracket 61 and a left mounting frame 62 arranged on the left side of the bottom bracket 61; a traveling mechanism 611 capable of traveling on the track group 1006 at the bottom of the sterilization chamber 1001 is arranged at the bottom of the bottom bracket 61. The traveling mechanism 611 can be a traveling wheel group capable of traveling on the track group 1006, or other structural forms, which are not limited here. The traveling mechanism 611 belongs to a conventional structure.

[0060] A number of groups of bottom spraying groups 63 are arranged at intervals from top to bottom on the left mounting frame 62. Each group of bottom spraying groups 63 is composed of a number of horizontal spraying pipes arranged at intervals from front to back. A number of first spray heads 631 spraying upward are installed at intervals from left to right on the pipe wall of each horizontal spraying pipe; a vertical spraying pipe 64 is arranged on the right side of the bottom bracket 61, and a number of second spray heads 641 spraying leftward are installed at intervals from top to bottom on the pipe wall of the vertical spraying pipe 64; the vertical spraying pipe 64 and each horizontal spraying pipe are connected to the hose 65 through the water passage on the spraying frame, and the hose 65 is communicated with the outlet of the corresponding branch spraying medium inlet pipe 56. When carrying out spraying cleaning and sterilization, hot water enters the corresponding hose 65 through each branch spraying medium inlet pipe 56, and then is sprayed through each first spray head 631 and each second spray head 641.

[0061] The above-mentioned large-scale mobile cleaning, sterilization and drying system is equipped with a number of hanging trolleys 7. A horizontally placed hoisting beam 1005 is hung at the top inside the sterilization chamber 1001 from front to back. There is also an external hoisting beam outside the sterilization cabinet 1 that can be docked with the hoisting beam 11. The hanging trolley 7 can be transferred from outside the sterilization cabinet 100 to the hoisting beam 1005 inside the sterilization cabinet 100 through the external hoisting beam, or transferred from inside the sterilization cabinet 100 to outside the sterilization cabinet 100 through the hoisting beam 1005 inside the sterilization cabinet 1.

[0062] As Figure 6As shown in the figure, the hanging trolley 7 includes: a hanging frame, which is composed of a bottom frame 71, a right frame 72 arranged on the right side of the bottom frame 71, and a top frame 73 arranged on the top of the right frame 72. A sliding mechanism is arranged on the top of the top frame 73, which can be hung on the hoisting beam 1005 and can slide along the axis direction of the hoisting beam 1005 under the action of an external force; the space between the bottom frame 71, the right frame 72 and the top frame 73 is a placement space for placing products to be processed. A number of sets of shelving groups 75 are arranged on the right frame 72 at intervals from top to bottom. Each shelving group 75 is located in the placement space, and at least one product to be processed is placed from front to back on each set of shelving groups 75; when the product to be processed is a freeze-drying tray, when each set of shelving groups 75 holds one freeze-drying tray, it can be two shelving rods that can hold the flying wings passing through both sides of the freeze-drying tray. The freeze-drying tray will not break away from the shelving rods under the action of the spray impact force. When each set of shelving groups 75 holds at least two freeze-drying trays, the number of shelving rods will increase accordingly.

[0063] When the hanging trolley 7 enters any one of the spray devices, a set of shelving groups 75 enters the space between two adjacent bottom spray groups 63. The right frame 72 enters the space between the vertical spray pipe 64 and each bottom spray group 73, and there are holes on the right frame 72 for the spray medium sprayed by each second spray head 641 to pass through. The bottom frame 71 enters the space between the lowermost bottom spray group and the bottom support 61.

[0064] At this time, when the hanging trolley 7 moves back and forth on the hoisting beam 1005 under the action of an external thrust force, the hanging trolley 7 and the freeze-drying trays loaded on the hanging trolley 7 will not touch any part of the spray device 300. When the spray device 300 moves back and forth on the track group 1006, each part of the spray device 300 will not touch the hanging trolley 7 and the freeze-drying trays loaded thereon.

[0065] Taking the freeze-drying tray as an example, the side of the freeze-drying tray that bears the items is placed face down. At this time, each first spray head 631 sprays upward, just spraying and flushing the side that bears the items. For the right frame 72 here, it can be composed of several beams spliced and connected by screws or welding or other fixed connection methods. At this time, the gap between the beams is the hole for the spray medium sprayed by each second spray head 641 to pass through, and the side of the freeze-drying tray is sprayed and flushed through each second spray head 641. Each rotating cleaning ball 200 sprays downward.

[0066] There are many structural forms of the sliding structure. Considering the overall structural layout here, the sliding structure is designed as follows, such as Figure 6 and Figure 7As shown in the figure, the sliding mechanism is as follows: a sliding seat 74 is provided on the top of the top frame 73. A sliding groove 741 is provided downward on the top of the sliding seat 74. At least two left rollers 742 are provided on the left side of the sliding groove 741, and at least two right rollers 743 are provided on the right side of the sliding groove 741. A space for the hoisting beam 1005 to penetrate is formed among the left rollers 742, the right rollers 743 and the sliding groove 741. When the suspended trolley 7 is suspended on the hoisting beam 1005, the left rollers 742 and the right rollers 743 are in rolling contact with the upper semi-circular arc surface of the hoisting beam 1005, and the hoisting beam 1005 is not in contact with the sliding groove 741.

[0067] In order to ensure that the suspended trolley 7 does not tilt when it is suspended on the hoisting beam 1005, a counterweight 721 is provided on the right frame 72. The top surface of the top frame 73 is an inclined surface 731. The inclined surface 731 is provided to guide the condensed water generated during the freeze-drying process to slide down and not accumulate on the top surface of the top frame 73 during the freeze-drying process. In addition, it can also prevent cleaning water and condensed water from accumulating on the top surface of the top frame 73 during the cleaning and sterilization process.

[0068] Each rotating cleaning ball 200 is located above each spraying device. Each spraying device 300 is driven by a driving structure to move forward or backward synchronously in the same direction on the track group 1006, so as to perform all-round spraying cleaning and sterilization on all products to be processed in the sterilization chamber 1001. The rotating cleaning ball plus the mobile spraying device 300 realizes multi-angle and multi-directional spraying and flushing, and there is basically no dead angle in the cleaning and sterilization, greatly improving the cleanliness of the cleaning and sterilization, and ensuring that the freeze-drying tray after use reaches the required cleanliness after being cleaned, sterilized and dried by a large-scale mobile cleaning, sterilization and drying system described in this solution.

[0069] During the forward and backward movement of each spraying device, in order to facilitate the management of the hose 65, a more preferred solution is to provide a spring 66 in the sterilization chamber 1001. Each hose 65 corresponds to at least one spring 66. One end of the spring 66 is fixed to the inner wall of the sterilization chamber 1001, and the other end of the spring 66 is fixed to the corresponding hose 65.

[0070] There are many structural forms of the driving structure. Considering the optimization of the overall structure and the use environment, the driving structure is designed as follows. Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown in the figure, in this embodiment, the driving structure is as follows: each spraying device 300 is arranged at intervals from front to back, and each spraying device 300 is connected by a total connecting frame 700. A first connecting block 8 is fixedly installed in a sealed manner in a through hole at the rear of the sterilization cabinet 100. The front end of the first connecting block 8 is located inside the sterilization chamber 1001, and the rear end of the first connecting block 8 is located outside the sterilization cabinet 100. A through channel 81 penetrating through the front and rear is provided in the first connecting block 8; The push rod 82 is hermetically inserted into the channel 81. The sealing structure can adopt a skeleton oil seal, a sealing ring, etc. They can be used in combination or multiple types can be mixed. There is no requirement here, as long as the required sealing requirement is met. The front end of the push rod 82 is fixedly connected to the total connecting frame 700. An internal threaded channel 821 is provided inwards at the rear end of the push rod 82. The screw rod 83 is screwed into the internal threaded channel 821. The rear end of the screw rod 83 extending out of the internal threaded channel 821 is fixedly connected to the output shaft of the reduction motor 84. And the push rod 82 is circumferentially limited by a guiding structure, so that when the screw rod 83 rotates forward or backward, it can only force the push rod 82 to move forward or backward; Here, the guiding structure can adopt a guide rail-slider structure, or a guide rod-sliding sleeve structure, or other structures on the market. The guiding structure belongs to a conventional structure in this field, so it will not be elaborated here. A platform 800 can be arranged outside the sterilization cabinet 100. The push rod 82 can be arranged on the platform 800 through the guiding structure, and the reduction motor 84 is also fixed on the platform 800.

[0071] As Figure 9 shown, a corrugated pipe 85 is sleeved on the push rod 82 located inside the sterilization chamber 1001. A second connecting block 822 is fixedly arranged on the front section of the push rod 82. The front end of the corrugated pipe 85 is hermetically and fixedly connected to the second connecting block 822, and the rear end of the corrugated pipe 85 is hermetically and fixedly connected to the first connecting block 8. Among them, the sealing method between the front end of the corrugated pipe 85 and the second connecting block 822, and the sealing method between the rear end of the corrugated pipe 85 and the first connecting block 8 can adopt a sealing structure such as a sealing ring. There is no requirement here, as long as the required sealing requirement is met. The arrangement of the corrugated pipe 85 ensures that during the forward or backward movement of the push rod 82, the fluid in the sterilization chamber 1001 will not leak out through this position of the driving structure.

[0072] The way that the front end of the push rod 82 is fixedly connected to the total connecting frame 700 adopts the following structure: As Figure 9 And Figure 10As shown, an installation block 7001 is provided on the rear end of the total connecting frame 700. A hemispherical positioning hole 7002 is inwardly formed on the surface of the installation block 7001. The head of the push rod 82 from front to back is successively: a hemispherical body 823 matching the hemispherical positioning hole 7002, and a connecting shaft 824 with a diameter smaller than that of the hemispherical body 823. After the limiting member 86 is clamped on the connecting shaft 824, it is fixedly connected to the installation block 7001, so as to limit the hemispherical body 823 in the hemispherical positioning hole 7002. In actual installation, it is very difficult to ensure that the total connecting frame 700 and the push rod 82 are exactly on the same axis. In addition, errors will also occur due to wear during use. The above structure has a self-adjusting function. When the total connecting frame 700 and the push rod 82 are not exactly on the same axis and there is an installation error, or after long-term use and wear, through the cooperation and adjustment of the hemispherical body 823 and the hemispherical positioning hole 7002, it can still ensure that the driving structure can operate smoothly.

[0073] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in any other form. Any modification or equivalent change made according to the technical essence of the present invention still belongs to the scope protected by the present invention.
