[0002] At present, freeze dryers are used in more and more fields, especially in GMP workshops of pharmaceutical factories. The freeze dryer itself is located in a clean, uncontrolled area, while the material inlet and outlet are located in a clean area. It is generally used for freeze drying of products, which has a great impact on product quality. The observation window of existing freeze dryers is mostly located on the side panel, and a lighting is provided at the window of the observation window to facilitate observation of the situation inside the freeze dryer. During the freeze drying experiment of new product development, researchers need to observe the status of the freeze-dried products from time to time. Since the freeze dryer control panel or control computer is mostly located in the clean area, the operator needs to go back and forth between the clean area and the non-clean area repeatedly, and the process of changing clothes in the middle is cumbersome and time-consuming, making it extremely inconvenient to use.

[0003] The problems mentioned above have certain limitations on ordinary freeze dryers and also have a great impact on the real-time observation of materials being processed by vacuum freeze dryers. Lack of timely observation may lead to reduced quality of the final product or even experimental failure. Utility Model Content

[0030] A vacuum freeze dryer with remote real-time monitoring by a camera, comprising:

[0031] Box 1;

[0032] Frame 4, frame 4 is fixedly connected to the upper end of the box body 1, and the upper end of the frame 4 is threadedly connected to the sealing plate 5 by bolts;

[0033] The screw nut 8 is rotatably connected to the frame 4;

[0034] Polished rod 7, polished rod 7 is connected to frame 4;

[0035] The screw nut 8 is connected between the polished rod 7 and the screw rod 6;

[0036] The connecting frame 9 is fixedly connected to the lower end of the screw nut 8, and the connecting frame 9 is connected to a camera 10 with light;

[0037] The lower shelf 17 is fixedly connected to the lower inner wall of the box body 1. The upper end of the lower shelf 17 is fixedly connected to the slide rail 18. The upper end of the slide rail 18 is connected to the freeze-drying rack 19. The freeze-drying rack 19 is matched with the camera 10 with light.

[0038] In a specific embodiment of the present invention, the housing 1 serves as the foundation for the entire apparatus, providing a sealed working environment. A vacuum is maintained internally to facilitate the freeze-drying process. A frame 4 is fixedly connected to the upper end of the housing 1, providing a mounting base for other components, such as the lead screw nut 8 and polished rod 7. A sealing plate 5 ensures airtightness at the top of the housing, preventing air from entering and affecting the freeze-drying effect. The lead screw nut 8 is driven by a motor to rotate, allowing the lead screw nut to move up and down along the lead screw, driving the connecting frame 9 and the illuminated camera 10 for vertical position adjustment. The polished rod 7 acts as a guide, ensuring that the lead screw nut 8 can only move in a straight line, thereby enhancing system stability. The lead screw 6 works in conjunction with the lead screw nut 8, driven by a motor for precise position control. The connecting frame 9 supports and secures the illuminated camera 10. As the lead screw nut moves, the connecting frame can carry the camera to a specified height to monitor the materials on the freeze-drying rack 19. The illuminated camera 10 is equipped with an illumination device, enabling clear images of the materials during the freeze-drying process in low-light conditions. The camera is connected to the control system, enabling remote, real-time monitoring. Users can view the drying chamber's conditions online and keep abreast of drying progress and status. Lower shelf 17 provides mounting space for slide rails 18. These rails provide a sliding path for freeze-drying racks 19, facilitating the loading and unloading of materials to be dried. Freeze-drying racks 19 are used to hold materials for freeze-drying.

[0039] For details, please refer to Figure 1-4The lower end of the box body 1 is fixedly connected to a lower frame 21, the upper end of the lower frame 21 is fixedly connected to a radiator 22 and a compressor 23, a condenser 20 is fixedly connected inside the box body 1, and the condenser 20, the radiator 22 and the compressor 23 are connected through a connecting pipe.

[0040] In this embodiment, the lower frame 21 provides a stable mounting platform for the radiator 22 and compressor 23, ensuring that these critical components remain stable during operation and avoid displacement caused by vibration or external forces. The main function of the radiator 22 is to absorb heat from the high-temperature, high-pressure gas generated during the condensation process and dissipate it to the environment to maintain the system's thermal balance. Temperature control: This effectively reduces the temperature within the condenser tube 20, ensuring smooth liquefaction of the refrigerant, thereby improving freeze-drying efficiency. Compressor protection: This effectively dissipates heat to prevent the compressor from overheating, extending its service life and ensuring normal operation. The compressor 23, as the core power source of the refrigeration system, is responsible for drawing in low-temperature, low-pressure gaseous refrigerant and, after compression, discharging high-temperature, high-pressure gaseous refrigerant, driving the entire refrigeration cycle. Pressure regulation: This allows the refrigerant to complete the evaporation and condensation processes at different stages, achieving a cooling effect. System start and stop: This system automatically starts and stops as needed to adjust the temperature within the freeze-drying chamber and ensure optimal drying conditions. The condenser tube 20 is the key point where the refrigerant transforms from gas to liquid. High-temperature, high-pressure gaseous refrigerant from the compressor enters the condenser, where it is cooled into liquid form, releasing a significant amount of heat. This heat is then removed by the radiator. Heat transfer: This efficiently transfers the heat generated during the condensation process to the surrounding medium, such as air or water, ensuring that the refrigerant is quickly cooled and ready for the next cycle. Connection: The condenser is connected to other components via connecting pipes, forming a complete refrigeration circuit and ensuring smooth refrigerant flow throughout the system.

[0041] For details, please refer to Figure 1-4 The front end of the box body 1 is rotatably connected to the door panel 2 through a rotating shaft, and the side end of the door panel 2 is connected to the observation window 3.

[0042] In this embodiment: the door panel 2 is rotatably connected to the front end of the box body 1 through a rotating shaft, ensuring that the door panel can be tightly closed to form a good airtight environment. This is crucial for the vacuum freeze-drying process, because any infiltration of outside air will affect the internal vacuum and temperature stability. The observation window 3 is located at the side end of the door panel 2, so that the user can directly view the freeze-drying status inside the box without opening the door panel. This not only reduces the temperature fluctuations caused by frequent opening and closing of the door, but also avoids destroying the vacuum environment. The observation window is usually made of high-strength transparent materials such as special glass or plastic, which can not only ensure clear vision, but also withstand a certain pressure difference and low temperature environment, ensuring long-term use without deformation or damage.

[0043] For details, please refer to Figure 1-4 The upper end of the box body 1 is fixedly connected to the motor 12, the output end of the motor 12 is fixedly connected to the second sprocket 13, the side end of the screw nut 8 is fixedly connected to the first sprocket 11, and the first sprocket 11 and the second sprocket 13 are meshed and rotated with a tooth chain 14.

[0044] In this embodiment: the motor 12 serves as the power source of the entire lifting system, providing precise and stable power output. It can start, stop or change the speed according to the instructions issued by the control system to meet different operational requirements. It is fixedly connected to the upper end of the box body 1, ensuring the stability and safety of the motor while reducing the space occupied by the box body. The second sprocket 13 is fixedly connected to the output end of the motor 12, responsible for transmitting the power of the motor to the toothed chain 14, and driving the first sprocket 11 to rotate through the toothed chain. Matching with the first sprocket 11, it ensures the smoothness and accuracy of power transmission and reduces energy loss and noise generation. The first sprocket 11 is fixedly connected to the side end of the screw nut 8. As the sprocket rotates, the screw nut moves up and down along the screw 6, thereby realizing the height adjustment of the camera with light 10. The toothed chain 14 is engaged and rotated between the first sprocket 11 and the second sprocket 13, serving as a connecting piece between the two, ensuring the effective transmission of power.

[0045] For details, please refer to Figure 1-4 The upper end of the box body 1 is fixedly connected with a controller 15.

[0046] In this embodiment, the controller 15 serves as the core control unit of the entire vacuum freeze dryer, integrating the operation and monitoring functions of various key components such as the motor, compressor, condenser, etc. The user can complete all necessary settings and operations through a single interface, simplifying the use process.

[0047] For details, please refer to Figure 1-4 A display screen 16 is fixedly connected to the side end of the box body 1.

[0048] In this embodiment, the display screen 16 is used to display the working status of the vacuum freeze dryer in real time, including key parameters such as temperature, humidity, vacuum degree, operating time, etc. The user can understand the current operating status of the device at a glance.

[0049] The working principle and usage process of the present invention are as follows: first, open the door panel 2 connected to the front end of the box by a rotating shaft, ensure that the door panel is fully open for easy operation, place the material to be freeze-dried on the freeze-drying rack 19, and then push the freeze-drying rack into the box along the slide rail 18, ensuring that the door panel 2 is tightly closed to form a good airtight environment to maintain the internal vacuum state, enter the control system through the display screen 16 at the side end of the box, set the required temperature, vacuum degree, running time and other parameters, select the appropriate freeze-drying program according to the characteristics of the material, and after confirming that all settings are correct, press the start button to start the freeze-drying process. At this time, the compressor 23, condenser 20 and radiator 22 will work together to establish a low-temperature and low-pressure environment. Use the display screen 16 to monitor various parameters of the freeze-drying process in real time, such as temperature, humidity, vacuum degree, etc. At the same time, check the material status through the observation window 3 or the camera with light 10 to ensure that the process is proceeding smoothly. If the system detects an abnormality, the display screen will sound an alarm and display a specific error message.
