Description

Technical Field

[0001] This utility model relates to the field of industrial freeze-drying equipment technology, and in particular to an industrial freeze-drying equipment with an observation device. Background Technology

[0002] In modern industrial production, vacuum freeze-drying technology is widely used in pharmaceuticals, food, and biological products due to its ability to dry at low temperatures and preserve material properties. As a key piece of equipment, the performance of industrial freeze-drying equipment directly affects product quality and production efficiency. As various industries increase their requirements for the quality of freeze-dried products, the limitations of traditional equipment that relies solely on instrument parameters to monitor the process become apparent. For example, the pharmaceutical industry has stringent requirements for the preservation of drug activity, appearance, and moisture content, while the food freeze-drying field also needs to control the rehydration properties and color of products. As a result, industrial freeze-drying equipment with observation devices has emerged to meet the needs of precision production.

[0003] Industrial freeze-drying equipment with observation devices integrates visualization components on the basis of traditional freeze dryers. In conjunction with the vacuum freeze-drying process, during the pre-freezing stage, the material is frozen into a solid state through the refrigeration system, and the observation device monitors the freezing uniformity. During the sublimation stage, ice crystals sublimate into water vapor under low vacuum, and the observation window or camera records the changes in the material's morphology in real time. During the desorption stage, the temperature is raised to remove bound water, and the final morphology is observed. The observation device includes a high-vacuum sealed observation window, LED light source, and camera. Some are equipped with microscopic or thermal imaging modules. The image data is linked with the control system, which can trigger alarms or optimize parameters. It also features vacuum sealing, low-temperature anti-condensation, and aseptic adaptability, achieving precise monitoring and quality improvement of the freeze-drying process.

[0004] Currently, industrial freeze-drying equipment with observation devices has a positive effect on the industry and freeze-dried raw materials. However, it still faces challenges when processing high-viscosity raw materials. Due to strong intermolecular forces, high-viscosity raw materials are prone to forming uneven ice crystal networks during the pre-freezing stage. After freezing, the internal porosity is low. When entering the sublimation stage, after the surface water sublimates, the internal viscous matrix shrinks rapidly, causing the particles to squeeze and stick together, forming dense clumps. Clumps not only hinder the subsequent removal of bound water and prolong the drying cycle, but also cause poor resolubility and uneven appearance of freeze-dried products. They can even cause degradation of active ingredients due to local overheating. Although the observation device can capture the clumping trend in real time, traditional processes cannot fundamentally solve the cohesion problem of high-viscosity materials. Therefore, an industrial freeze-drying equipment with an observation device is proposed to solve the above problems. Utility Model Content

[0036] This utility model has the following beneficial effects:

[0037] 1. In this utility model, by starting the motor inside the housing, the drive end drives the rotating disk to make a circular motion. The protrusions on the edge of the rotating disk rotate periodically along a specific trajectory. Since the sliding column is located on the trajectory of the protrusions, when the two come into contact, the sliding column will have a change in height. This change is transmitted to the transition plate, causing it to vibrate at high frequency. When freeze-drying high-viscosity raw materials, the high-frequency vibration of the transition plate can break the adhesion tendency between raw material particles, keeping them loose during the pre-freezing and sublimation stages and avoiding clumping. This not only ensures uniform and efficient moisture removal, but also improves the device's ability to process high-viscosity materials, reduces problems such as prolonged drying cycles and uneven product quality, and greatly improves the overall operating efficiency.

[0038] 2. In this utility model, the rotating column fixed to the top of the rotating disk transmits rotational motion, driving the support plate to make circumferential motion. The outer wall of the roller disk contacts the inner wall of the shell. Due to the difference in length and width of the internal space of the shell, the roller disk is squeezed by the inner wall contour when it rotates to different positions, pushing the slide plate to squeeze the second spring to store energy. When it reaches a more distant position, the second spring releases energy and pushes the slide plate to move, so that the combined length of the slide plate and the support plate is adjusted in real time with the trajectory of the roller disk. During the process, the second scraper and the first scraper maintain a stable contact area with the transition plate. The cylinder and the first spring cooperate. When the transition plate moves up, the first scraper squeezes the first spring to store energy. When it moves down, it releases energy to reset. This ensures that the scraper assembly and the transition plate are tightly attached during vibration, avoiding uneven drying caused by local accumulation of raw materials, and improving the efficiency of the device and the utilization rate of raw materials.

[0045] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0046] Reference Figures 1 to 3An embodiment of this utility model is provided: an industrial freeze-drying device with an observation device, including a shell 1, observation mechanisms 2 fixedly connected to both sides of the shell 1, a detection mechanism 3 fixedly connected to the inside of the shell 1, and a composite mechanism 4 fixedly connected to the inside of the shell 1. The freeze-drying process is visualized and monitored and high-viscosity raw materials are prevented from caking through the cooperation of multiple mechanisms.

[0047] Specifically, the observation unit 2 monitors the freeze-drying process in real time, the detection unit 3 collects data such as temperature and humidity, and the composite unit 4 stirs and breaks up the high-viscosity raw materials to prevent clumping. The collaboration of multiple units ensures uniform and efficient freeze-drying, realizes visual monitoring and anti-caking treatment, and improves freeze-drying quality and efficiency.

[0048] The composite mechanism 4 includes a motor 41, and a vibration component 42 is fixedly connected to the drive end of the motor 41. The vibration component 42 includes a rotating disk 421, one side of which is fixedly connected to the drive end of the motor 41. Three protrusions 422 are fixedly connected to the top of the rotating disk 421. A transition plate 5 is slidably connected to the inner wall of the housing 1. Three sliding columns 423 are fixedly connected to the bottom of the transition plate 5. When the motor 41 inside the housing 1 is turned on, the motor 41 drives the rotating disk 421 to make a circular motion, which drives the protrusions 422 to make a periodic circular motion along a predetermined route. The sliding columns 423 are on the movement path of the protrusions 422. When they come into contact, a height difference is generated, so that the transition plate 5 is subjected to the action of the sliding columns 423 to achieve high-frequency vibration, which effectively prevents the agglomeration of highly viscous raw materials and improves the work efficiency. A rotating column 43 is fixedly connected to the top of the rotating disk 421, and an anti-stacking component 44 is fixedly connected to the outer wall of the rotating column 43.

[0049] Specifically, the rotating disk 421 is driven by the motor 41 to rotate, which causes the protrusion 422 to periodically impact the sliding column 423, causing the transition plate 5 to vibrate at high frequency, effectively breaking up raw material lumps and preventing the accumulation and agglomeration of highly viscous materials. At the same time, the rotating column 43 drives the anti-agglomeration component 44 to rotate, further dispersing the material and enhancing its fluidity. This design combines the dual effects of vibration and stirring, significantly improving freeze-drying uniformity, reducing manual intervention, lowering energy consumption, and increasing production efficiency. The vibration structure is simple and reliable, with low maintenance costs, and is suitable for continuous freeze-drying of highly viscous materials, ensuring stable product quality.

[0050] The anti-stacking component 44 includes a support plate 441, one side of which is fixedly connected to the outer wall of a rotating column 43. The rotating column 43, fixed to the top of a rotating disk 421, synchronously transmits the rotation of the rotating disk 421, causing the support plate 441 to perform circular motion. This, in conjunction with the anti-stacking component 44, enables dynamic intervention against material accumulation. A sliding plate 443 is slidably connected to the inner wall of the support plate 441. A fixing column 445 is fixedly connected to one side of the sliding plate 443. A second spring 446 is sleeved on the outer wall of the fixing column 445. Cylinders 448 are slidably connected to the inner walls of both the sliding plate 443 and the support plate 441. Springs 444 are sleeved on the outer walls of both cylinders 448. The bottoms of both cylinders 448 are fixedly connected to the outer walls of both cylinders 448. A scraper 442 is fixedly connected to the slide plate 443. A roller 449 is fixedly connected to the side of the slide plate 443 away from the support plate 441. The outer wall of the roller 449 contacts the inner wall of the housing 1. A scraper 447 is fixedly connected to the bottom of the slide plate 443. Since the outer wall of the roller 449 contacts the inner wall of the housing 1, the length and width of the housing 1 are different. The roller 449 presses the slide plate 443 towards the rotating column 43 at different positions, compressing the spring 446 to store energy. When it moves to a more distant position, the spring 446 releases energy and pushes the slide plate 443 to move. This allows the length of the slide plate 443 and the support plate 441 to be adjusted in real time as the roller 449 rotates on the inner wall of the housing 1, keeping the contact area between the scraper 447, the scraper 442, and the transition plate 5 unchanged.

[0051] Specifically, when the anti-stacking component 44 is working, the rotating column 43 drives the support plate 441 to rotate, and the roller 449 rolls along the inner wall of the shell 1. Due to the uneven length and width of the shell 1, the roller 449 undergoes displacement changes at different positions: when it is close to the narrow side, it squeezes the sliding plate 443 and compresses the second spring 446; when it moves to the wide side, the second spring 446 rebounds and pushes the sliding plate 443 outward. This dynamic adjustment ensures that the scraper 442, buffered by the first spring 444, and the scraper 447 always fits against the transition plate 5, forming an adaptive scraping structure. The first spring 444 ensures that the scraper 442 makes flexible contact, while the second spring 446 adjusts the extension and retraction range of the scraper 447. The two work together to achieve scraping without dead angles and effectively prevent the accumulation of raw materials.

[0052] Reference Figures 2 to 4The observation mechanism 2 includes a housing 21. One side of the housing 21 is fixedly connected to one side of the housing 1. A rotating plate 22 is rotatably connected to the outer wall of the housing 21. A cover plate 23 is fixedly connected to the other side of the rotating plate 22. A fixing block 24 is fixedly connected to one side of the cover plate 23. A limiting block 25 is fixedly connected to the outer wall of the housing 21. The observation mechanism 2 forms an openable and closable observation channel through the cooperation of the housing 21, rotating plate 22, cover plate 23, fixing block 24 and limiting block 25, which makes it convenient for operators to observe the freeze-drying status of the raw materials in the housing 1 in real time. Three sliding columns 423 are slidably connected to the top of the rotating disk 421. The outer wall of the rotating disk 421 is rotatably connected to the inner wall of the housing 1. The fixing block 24 and the limiting block 25 are fixedly connected by screws 26. Three sealing strips 6 are provided on the outer wall of the housing 1. The screws 26 are fixed to ensure the structural stability of the observation mechanism 2 when it is closed. The sealing strips 6 ensure the sealing of the housing 1 and maintain the vacuum environment required for freeze-drying.

[0053] Specifically, the observation window is opened or closed by rotating the rotating plate 22 to drive the cover plate 23. The fixing block 24 and the limiting block 25 are locked and fixed by screws 26 to ensure the structural stability when the observation window is sealed. A sealing strip 6 is set at the connection between the outer shell 21 and the shell 1 to maintain the airtightness of the equipment in the closed state and maintain the vacuum environment required for the freeze-drying process. During operation, the screws 26 can be loosened and the cover plate 23 can be rotated to a suitable angle to monitor the freeze-drying status of the material in real time through the transparent observation window without breaking the internal vacuum. This design realizes non-invasive visual monitoring, which not only meets the process sealing requirements, but also facilitates status inspection and quality control during the production process.

[0054] The detection mechanism 3 includes a support 31. The top of the support 31 is movably connected to the inner wall of the housing 1. A camera 32 is fixedly connected to the outer wall of the support 31. A supplementary light 33 is fixedly connected to the bottom of the support 31. Two push rods 36 are movably connected to the inner wall of the housing 1. A slider 35 is fixedly connected to the side of the two push rods 36 that are close to each other. A partition 34 is fixedly connected to the bottom of the two sliders 35. The detection mechanism 3, through the cooperation of the camera 32 and the supplementary light 33, realizes the image acquisition of the freeze-drying process. The push rods 36, sliders 35 and partition 34 are linked together, and the detection angle can be adjusted or different raw material areas can be separated according to the monitoring needs, thereby improving the flexibility and accuracy of monitoring. The outer wall of the rotating column 43 is movably connected to the inner wall of the transition plate 5. The tops of the two sliders 35 are slidably connected to the inner wall of the housing 1, so that the sliders 35 can slide on the inner wall of the housing 1 under the action of external force.

[0055] The outer wall of scraper 2 447 is slidably connected to the inner wall of one of scrapers 1 442. A roller 449 is fixedly connected to one side of the slide plate 443. The bottoms of both scraper 2 447 and scraper 1 442 are slidably connected to the top of the transition plate 5. The outer wall of the fixing column 445 is slidably connected to the inner wall of the support plate 441. One side of spring 2 446 is fixedly connected to the outer wall of the slide plate 443, and the other side of spring 2 446 is fixedly connected to the inner wall of the support plate 441. Through the sliding and elastic connection design of the above structure, the anti-caking assembly 44 maintains stable contact with the transition plate 5 during dynamic adjustment, ensuring the continuity of the anti-caking function. For continuity and reliability, the top of one spring-444 contacts the inner wall of the support plate 441, the top of another spring-444 contacts the inner wall of the slide plate 443, the bottom of one spring-444 contacts the inner wall of one scraper-442, and the bottom of another spring-444 contacts the inner wall of another scraper-442. The bidirectional elastic support of the spring-444 allows the scraper-442 to adaptively adjust the pressure with the vibration of the transition plate 5 and to quickly reset after vibration, further enhancing the dynamic intervention effect of the anti-stacking assembly 44 on highly viscous materials.

[0056] Working principle: The motor 41 located inside the housing 1 is activated, driving the rotating disk 421 to perform circular motion. This causes the rotating disk 421 to drive the protrusion 422 to perform periodic circular motion along a predetermined path. The sliding column 423 is positioned precisely on the predetermined path of the protrusion 422, creating a height difference when it contacts the protrusion 422. This causes the transition plate 5 to vibrate at high frequency due to the action of the sliding column 423, effectively preventing the agglomeration of highly viscous raw materials and significantly improving the device's operating efficiency. The rotating column 43, fixed to the top of the rotating disk 421, synchronously transmits the rotation of the rotating disk 421, causing the support plate 441 to perform circular motion. Because the outer wall of the roller 449 contacts the inner wall of the housing 1, and the length and width of the housing 1 are different, the roller 449 presses the sliding plate 443 towards the rotating column 43 at different positions. This causes the sliding plate 443 to press the second spring 446. At this time, the second spring 446... Elastic deformation generates and stores elastic potential energy. When the roller 449 moves to a more distant position, the second spring 446 releases a portion of the elastic potential energy to push the slide plate 443 to move. This allows the lengths of the slide plate 443 and the support plate 441 to be adjusted in real time as the roller 449 rotates on the inner wall of the housing 1. This ensures that the contact area between the second scraper 447, the first scraper 442, and the transition plate 5 remains constant. Furthermore, due to the cooperation of the cylinder 448 and the first spring 444, when the transition plate 5 moves upward, the first scraper 442 squeezes the first spring 444. The elastic potential energy generated by the first spring 444 is released when the transition plate 5 moves downward, pushing the first scraper 442 to reset. This ensures that during the vibration of the transition plate 5, the second scraper 447 and the first scraper 442 remain tightly connected to the transition plate 5. This effectively prevents the problem of incomplete or excessive freeze-drying of some raw materials due to local accumulation during the freeze-drying process, significantly improving the overall efficiency of the device and the utilization rate of raw materials.
