Description

Technical Field

[0002] The Camellia chrysantha vacuum freeze-drying rapid molding device is used to freeze-dry Camellia chrysantha in a vacuum environment, rapidly molding it while retaining its original nutrients and quality. The principle is to first place fresh Camellia chrysantha in a low-temperature environment, freezing the water within it into solid ice. Then, under vacuum, heating and other methods are used to directly sublimate the solid ice into water vapor, achieving drying and rapid molding of the Camellia chrysantha.

[0003] In the related art, when the traditional camellia chrysantha vacuum freeze-drying rapid molding device is used, a large amount of camellia chrysantha is usually directly piled up and placed in the freeze-drying processing chamber of the device. During the freeze-drying process, the position of the camellia chrysantha is not easy to change, which may easily cause some of the camellia chrysantha to be unevenly freeze-dried and heated, hindering heat transfer and water sublimation, reducing the quality and efficiency of freeze-drying molding, and most of them lack the function of sterilizing and disinfecting the camellia chrysantha, and cannot realize the integrated operation of sterilization and freeze-drying molding of the camellia chrysantha. It is necessary to first use the disinfection and sterilization equipment to disinfect the camellia chrysantha, and then transfer it to the freeze-drying rapid molding device after the treatment is completed. The operation steps are cumbersome, waste time, and reduce work efficiency.

[0031] The technical solutions of this application will be described clearly and completely below with reference to specific embodiments. Obviously, the embodiments described are only a portion of the embodiments of this application, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of this application without creative effort are also within the scope of protection of this application.

[0032] First embodiment

[0033] See also Figure 1-Figure 5 In a first embodiment of the present application, a golden camellia vacuum freeze-drying rapid prototyping device comprises a freeze-drying cabinet 1 and a sealed cabinet door 2 rotatably mounted on the outside of the freeze-drying cabinet 1. A hydraulic cylinder 7 is fixedly mounted on the inner wall of the bottom of the freeze-drying cabinet 1. A load plate 8 is fixedly mounted on the output shaft end of the hydraulic cylinder 7. A motor 9 is fixedly mounted on the top of the load plate 8. A vertical shaft 10 is fixedly mounted on the output shaft end of the motor 9. A golden camellia placing mechanism 11 is arranged on the vertical shaft 10. The number of golden camellia placing mechanisms 11 is set to multiple groups, and the multiple groups of golden camellia placing mechanisms 11 are evenly distributed. The golden camellia placing mechanisms 11 are set to multiple groups and are evenly distributed, which can divide the golden camellia into multiple portions and place them separately in the freeze-drying cabinet 1, greatly reducing the situation where a large number of golden camellias are piled together, and can improve the quality of the golden camellia freeze-drying operation. The motor 9 drives the vertical shaft 10 to rotate, driving the golden camellia placing mechanism 11 to rotate, so that the golden camellia can be fully and evenly subjected to the refrigeration, heating and vacuum environment in the freeze-drying cabinet, thereby greatly improving the freeze-drying efficiency and quality.

[0034] In this embodiment, the golden camellia placement mechanism 11 includes a support frame 111, two vertical guide rods 112, two sliders 113, a mesh golden camellia placement frame 114 and a plurality of springs 115. The support frame 111 is fixedly mounted on the vertical shaft 10, and the two vertical guide rods 112 are fixedly mounted on the support frame 111. The two sliders 113 are respectively slidably mounted on the corresponding vertical guide rods 112. The outer walls of the two sides of the mesh golden camellia placement frame 114 are respectively fixedly connected to the side of the two sliders 113 close to each other. The tops of the multiple springs 115 are all fixed to the mesh golden camellia placement frame 11 4 is fixedly connected to the bottom outer wall, the bottom ends of multiple springs 115 are fixedly connected to the support frame 111, and the multiple springs 115 are evenly distributed. The top rod 15 is fixedly installed at the bottom center of the mesh camellia placement frame 114. A through hole is opened on the support frame 111, and the bottom end of the top rod 15 passes through the through hole. The mesh camellia placement frame 114 is adopted and slidably connected with the vertical guide rod 112 through the slider 113. With the elastic effect of the spring 115, the mesh camellia placement frame 114 can move up and down within a certain range, which is not only convenient for the placement and removal of the camellia , and under the action of the sliding ball 16 and the arc-shaped protrusion 14, the golden camellia can be dynamically adjusted during the freeze-drying process. By utilizing the telescopic characteristics of the hydraulic cylinder 7, the vertical shaft 10 can be controlled to rise and fall vertically, thereby making multiple groups of mesh golden camellia placement frames 114, multiple push rods 15 and multiple sliding balls 16 follow the vertical rise and fall, and the sliding height of the sliding ball 16 on the arc-shaped protrusion 14 can be changed, and the vibration amplitude of the mesh golden camellia placement frame 114 can be adjusted according to needs. When the golden camellia in the mesh golden camellia placement frame 114 is subjected to low-temperature freezing, a relatively small vibration is selected. The vibration amplitude makes the movement range of the golden camellia in the mesh golden camellia placement frame 114 relatively small, which can prevent the vibration amplitude from being too large and causing damage to the frozen golden camellia. When the golden camellia in the mesh golden camellia placement frame 114 is vacuum heated, a relatively large vibration amplitude is selected, so that the movement range of the golden camellia in the mesh golden camellia placement frame 114 is relatively large, which can improve the heating, drying and molding efficiency of the golden camellia. A limit block 116 is fixedly installed on the top of the vertical guide rod 112. The design of the limit block 116 can prevent the slider 113 from being separated from the vertical guide rod 112.

[0035] In this embodiment, a plurality of evenly distributed horizontal plates 12 are fixedly installed on the left inner wall of the freeze-drying cabinet 1, and a plurality of evenly distributed horizontal plates 13 are fixedly installed on the right inner wall of the freeze-drying cabinet 1. The top of the horizontal plate 12 and the top of the horizontal plate 2 13 are fixedly installed with a plurality of evenly distributed arc-shaped protrusions 14. The multiple arc-shaped protrusions 14 on the same horizontal plate 12 are evenly distributed with the vertical axis 10 as the center of the circle. The multiple arc-shaped protrusions 14 on the same horizontal plate 2 13 are evenly distributed with the vertical axis 10 as the center of the circle. The bottom of the multiple groups of camellia placement mechanisms 11 are all provided with a push rod 15, and the multiple push rods 15 The top of each frame is fixedly provided with a sliding ball 16, which is adapted to the arc-shaped protrusion 14. The sliding ball 16 at the bottom of the top rod 15 cooperates with the arc-shaped protrusion 14 on the horizontal plate 12 and the horizontal plate 2 13 and the spring 115. When the vertical shaft 10 drives the golden camellia placing mechanism 11 to rotate, the sliding ball 16 slides on the arc-shaped protrusion 14, and the top rod 15 moves up and down accordingly, causing the mesh golden camellia placing frame 114 to move up and down periodically along the vertical guide rod 112. This process allows the golden camellia to continuously change its position during the freeze-drying process, avoiding local uneven freeze-drying and uneven heating, and effectively improving the freeze-drying rapid molding effect.

[0036] In this embodiment, a refrigerator 3 is fixedly installed on the top of the freeze-drying cabinet 1, and the cooling end of the refrigerator 3 is located in the freeze-drying cabinet 1. The refrigerator 3 is used to refrigerate the inside of the freeze-drying cabinet 1, so that the water in the golden camellia is frozen into solid ice under a low temperature environment. A vacuum pump 4 is fixedly installed on the right outer wall of the freeze-drying cabinet 1, and an exhaust pipe 5 is fixedly installed on the suction end of the vacuum pump 4. A one-way valve is fixedly installed in the exhaust pipe 5, and one end of the exhaust pipe 5 extends into the freeze-drying cabinet 1. The vacuum pump 4, the exhaust pipe 5 and the one-way valve are set to vacuum the inside of the freeze-drying cabinet 1. An electric heating plate 6 is fixedly installed on the rear inner wall of the freeze-drying cabinet 1. The electric heating plate 6 is a temperature-adjustable electric heating plate. The electric heating plate 6 is used to heat the inside of the freeze-drying cabinet 1, and then under a vacuum environment, the solid ice is directly sublimated into water vapor by heating, thereby realizing the drying and rapid forming of the golden camellia.

[0037] In this embodiment, a crossbeam 17 located above the vertical axis 10 is fixedly installed on the inner wall of the rear side of the freeze-drying cabinet 1, and an axle seat 18 is fixedly installed on the bottom of the crossbeam 17. A guide column 19 is rotatably installed on the bottom of the axle seat 18. A guide groove is provided at the top of the vertical axis 10, and the bottom end of the guide column 19 is slidably installed in the guide groove, which can provide stable guidance for the rotation and vertical movement of the vertical axis 10, ensuring that its rotation and vertical lifting process are smooth, thereby enhancing the stability of the entire device during operation.

[0038] In this embodiment, a water vapor exhaust pipe 20 is fixedly installed on the top of the freeze drying cabinet 1, and a solenoid valve 21 is fixedly installed on the water vapor exhaust pipe 20. The design of the water vapor exhaust pipe 20 and the solenoid valve 21 facilitates the discharge of water vapor inside the freeze drying cabinet 1 to ensure the stability of the environment inside the freeze drying cabinet 1.

[0039] In this embodiment, a temperature sensor 22 and a pressure sensor 23 are fixedly installed on the left inner wall of the freeze-drying cabinet 1. The temperature sensor 22 is used to monitor the temperature inside the freeze-drying cabinet 1 in real time, and the pressure sensor 23 is used to monitor the pressure inside the freeze-drying cabinet 1 in real time, providing accurate data for the operator, facilitating timely adjustment of the freeze-drying parameters, and ensuring that the freeze-drying process is in the best state. An observation window 24 is fixedly installed on the sealed cabinet door 2. The design of the observation window 24 makes it convenient for the operator to observe the freeze-drying state of the Camellia chrysantha in the freeze-drying cabinet 1 at any time, without the need to frequently open the sealed cabinet door 2, to avoid the entry of outside air affecting the freeze-drying effect, thereby improving the convenience of operation.

[0040] In this embodiment, it should be noted that a controller is installed on the sealed cabinet door 2, and a display screen and multiple control buttons are provided on the controller. The refrigerator 3, vacuum pump 4, electric heating plate 6, hydraulic cylinder 7, motor 9, solenoid valve 21, temperature sensor 22 and pressure sensor 23 are all electrically connected to the controller. The temperature and pressure values monitored by the temperature sensor 22 and the pressure sensor 23 can be displayed on the display screen. Multiple control buttons can be used to control the opening and closing of the refrigerator 3, vacuum pump 4, electric heating plate 6, hydraulic cylinder 7, motor 9, solenoid valve 21, temperature sensor 22 and pressure sensor 23 respectively.

[0041] In this embodiment, through the above structure, when the golden camellia vacuum freeze-drying rapid prototyping device provided by the present application is used, first, the sealed cabinet door 2 is opened, the golden camellia air volume to be freeze-dried is divided into two parts and respectively laid in a plurality of mesh golden camellia placement frames 114, and then the sealed cabinet door 2 is closed to form a closed freeze-drying space; then, the refrigerator 3 is started, and the refrigeration end of the refrigerator 3 cools the interior of the freeze-drying cabinet 1, prompting the temperature in the cabinet to drop rapidly, freezing the moisture in the golden camellia, and laying the foundation for the subsequent vacuum freeze-drying operation;

[0042] Then, the motor 9 is started, and the motor 9 drives the vertical shaft 10 to rotate. The vertical shaft 10 further drives the multiple groups of golden camellia placing mechanisms 11 and the golden camellia laid thereon to perform circular motion synchronously. This process can make the golden camellia more fully contact the low-temperature environment in the freeze-drying cabinet 1, ensuring that the moisture in the golden camellia is more fully frozen into solid ice. When the golden camellia placing mechanism 11 rotates, the sliding ball 16 at the bottom of the push rod 15 rolls on the arc-shaped protrusion 14. Due to the special shape of the arc-shaped protrusion 14, under the elastic force of the spring 115, the movement trajectory of the sliding ball 16 causes the push rod 15 to move up and down. The up and down movement of the push rod 15 drives the mesh golden camellia placing frame 114 to perform periodic up and down movement along the vertical guide rod 112, thereby increasing the movement range of the golden camellia in the mesh golden camellia placing frame 114, further enhancing the comprehensiveness of the contact between the golden camellia and the low-temperature environment in the freeze-drying cabinet 1, and being able to more fully and comprehensively freeze the moisture in the golden camellia into solid ice.

[0043] After the moisture in the golden camellia is frozen, the refrigerator 3 is turned off and the vacuum pump 4 is turned on to evacuate the interior of the freeze-drying cabinet 1. After the vacuuming is completed, the vacuum pump 4 is stopped and the electric heating plate 6 is turned on to heat the golden camellia under a vacuum environment, so that the frozen moisture on the golden camellia can be directly sublimated from a solid state to a gaseous state. The solenoid valve 121 is opened as needed (the solenoid valve 121 is a one-way valve), and the sublimated water vapor can be discharged through the water vapor discharge pipe 20, so as to ensure that the freeze-drying process proceeds smoothly. At the same time, the motor 9 is used to drive the vertical shaft 10, the multiple groups of golden camellia placing mechanisms 11 and the golden camellia laid thereon to perform circular motion synchronously, thereby enhancing the comprehensiveness of the heat contact between the golden camellia and the freeze-drying cabinet 1, and being able to heat the golden camellia more comprehensively and evenly, so that the frozen moisture can be directly sublimated from a solid state to a gaseous state more comprehensively, fully and efficiently.

[0044] During the freeze-drying process of Camellia chrysantha, the temperature sensor 22 and the pressure sensor 23 can respectively monitor the temperature and pressure data in the freeze-drying cabinet 1 in real time. The operator can adjust the working status of the refrigerator 3, the vacuum pump 4, the electric heating plate 6 and other equipment according to these data to ensure that the entire freeze-drying process is carried out under the optimal parameters. At the same time, the operator can visually observe the freeze-drying state of Camellia chrysantha in the freeze-drying cabinet 1 through the observation window 24;

[0045] During the freeze-drying process of golden camellia, the hydraulic cylinder 7 can be used to control the vertical lifting of the vertical shaft 10, so that the multiple groups of mesh golden camellia placement frames 114, multiple push rods 15 and multiple sliding balls 16 can follow the vertical lifting, so that the sliding height of the sliding ball 16 on the arc-shaped protrusion 14 can be changed, and the vibration amplitude of the mesh golden camellia placement frame 114 can be adjusted according to needs; when the golden camellia in the mesh golden camellia placement frame 114 is subjected to low-temperature freezing, a relatively small vibration amplitude is selected, so that the golden camellia has a relatively small range of movement in the mesh golden camellia placement frame 114, which can prevent the frozen golden camellia from being damaged due to excessive vibration amplitude; when the golden camellia in the mesh golden camellia placement frame 114 is subjected to vacuum heating, a relatively large vibration amplitude is selected, so that the golden camellia has a relatively large range of movement in the mesh golden camellia placement frame 114, which can improve the heating, drying and molding efficiency of the golden camellia;

[0046] After the freeze-drying of the camellia chrysantha is completed, turn off the electric heating plate 6, stop the motor 9, open the sealed cabinet door 2, and take out the freeze-dried camellia chrysantha. It should be noted that before opening the sealed cabinet door 2, the vacuum degree inside the freeze-drying cabinet 1 must be destroyed first. A vacuum breaking valve and other components can be installed on the freeze-drying cabinet 1 to destroy the vacuum degree. The vacuum breaking valve is installed on the side wall of the freeze-drying cabinet 1. Before opening the sealed cabinet door 2, the vacuum breaking valve is opened to introduce outside air to destroy the vacuum environment inside the freeze-drying cabinet 1. Since the use of vacuum breaking valves and other components to destroy the vacuum degree is a mature technology in this field, it will not be described in detail in this article.

[0047] Second embodiment

[0048] Based on the camellia chrysantha vacuum freeze-drying rapid prototyping device provided in the first embodiment of the present application, the second embodiment of the present application proposes another camellia chrysantha vacuum freeze-drying rapid prototyping device. The second embodiment is merely a preferred method of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0049] The second embodiment of the present application will be further described below with reference to the accompanying drawings and implementation plans.

[0050] See also Figure 6-Figure 9 , a golden camellia vacuum freeze-drying rapid prototyping device:

[0051] In this embodiment, an ozone generator 25 is fixedly installed on the right outer wall of the freeze drying cabinet 1, and an ozone delivery pipe 26 is fixedly installed on the discharge end of the ozone generator 25. An electromagnetic flow regulating valve 27 is fixedly installed on the ozone delivery pipe 26. One end of the ozone delivery pipe 26 extends into the freeze drying cabinet 1. An ozone circulation pumping mechanism is provided on the left side of the freeze drying cabinet 1. The ozone circulation pumping mechanism includes a circulating air pump 28, an air suction pipe 29, a solenoid valve 2 30, a gas main pipe 31, a solenoid valve 3 32 and a plurality of gas branch pipes. 33, the circulating air pump 28 is fixedly mounted on the left outer wall of the freeze drying cabinet 1, one end of the suction pipe 29 is fixedly connected to the suction end of the circulating air pump 28, and the other end of the suction pipe 29 extends into the freeze drying cabinet 1, the electromagnetic valve 2 30 is fixedly mounted on the suction pipe 29, the gas main pipe 31 is fixedly connected to the discharge end of the circulating air pump 28, the electromagnetic valve 3 32 is fixedly mounted on the gas main pipe 31, one end of the multiple gas branch pipes 33 are fixedly connected to the gas main pipe 31, and the inner wall of the multiple horizontal plates 12 are provided with inlets. The other ends of the multiple gas delivery branches 33 extend into the corresponding air inlet chambers respectively. A plurality of evenly distributed ozone discharge holes 34 are provided on the top inner wall of the air inlet chamber. The ozone generated by the ozone generator 25 can be delivered into the freeze drying cabinet 1 through the ozone delivery pipe 26 to sterilize the golden camellia inside the freeze drying cabinet, prevent bacteria and microorganisms from contaminating the golden camellia, and further improve the freeze-drying quality of the golden camellia. The ozone circulation pumping mechanism causes the ozone to circulate in the freeze drying cabinet 1 to ensure that the golden camellia is sterilized without dead angles. Bacteria treatment can improve the sterilization effect. At the same time, the ozone delivery amount can be controlled by the electromagnetic flow regulating valve 27 as needed. An ozone sensor 35 is fixedly installed on the left inner wall of the freeze-drying cabinet 1. When the golden camellia inside the freeze-drying cabinet 1 is sterilized, the ozone sensor 35 can monitor the ozone concentration in the freeze-drying cabinet 1 to ensure the safety of ozone use and prevent the ozone concentration from being too high or too low, which affects the sterilization effect on the golden camellia. Specifically, the ozone concentration for sterilizing golden camellia can be controlled at 5-10ppm.

[0052] In this embodiment, it should be noted that the ozone generator 25, the electromagnetic flow regulating valve 27, the second solenoid valve 30, the third solenoid valve 32 and the ozone sensor 35 are all electrically connected to the controller, and the ozone concentration value monitored by the ozone sensor 35 can also be displayed on the display screen. Multiple control buttons can also be used to control the opening and closing of the ozone generator 25, the electromagnetic flow regulating valve 27, the second solenoid valve 30, the third solenoid valve 32 and the ozone sensor 35 respectively.

[0053] In this embodiment, through the above structure, when the golden camellia vacuum freeze-drying rapid molding device provided by the present application is used, the golden camellia to be freeze-dried is evenly divided into multiple portions and respectively laid in multiple mesh golden camellia placement frames 114, the sealed cabinet door 2 is closed, and before the golden camellia is freeze-dried and molded according to the operating steps of the first embodiment, the ozone generator 25 is first started to operate, and ozone is generated by the ozone generator 25. By opening the electromagnetic flow regulating valve 27, the ozone delivery amount can be adjusted according to actual needs, so that the ozone enters the freeze-drying cabinet 1 through the ozone delivery pipe 26. The ozone sensor 35 is used to monitor the ozone concentration in the cabinet in real time to ensure that it is within a safe and effective range, sterilize and disinfect the golden camellia inside the freeze-drying cabinet, prevent bacteria and microorganisms from contaminating the golden camellia, and prepare for subsequent golden camellia freeze-drying molding;

[0054] After the freeze-drying cabinet 1 is filled with ozone of appropriate concentration, the ozone generator 25 is stopped, and then the circulation air pump 28 is controlled to operate, and the solenoid valve 2 30 and the solenoid valve 3 32 are opened (the solenoid valve 2 30 and the solenoid valve 3 32 are both one-way valves), so that the ozone in the freeze-drying cabinet 1 can pass through the suction pipe 29, the circulation air pump 28, the gas main pipe 31, and the multiple gas branch pipes 33 to enter the air inlet cavity in the multiple horizontal plates 12 respectively, and then the ozone is discharged upward from the multiple ozone discharge holes 34, so that the ozone can circulate in the freeze-drying cabinet 1. At the same time, the motor 9 is controlled to operate, and the motor 9 is used to drive the vertical shaft 10, the multiple groups of golden camellia placement mechanisms 11 and the golden camellias laid thereon to perform circular motion synchronously, and cooperate with the golden camellia to move in the mesh golden camellia placement frame 114, constantly changing position, so that the ozone and the golden camellia are fully and fully in contact, thereby ensuring that the golden camellia is sterilized in a comprehensive and non-dead-angle manner, thereby improving the sterilization effect;

[0055] After the sterilization and disinfection of camellia chrysantha is completed, the circulation air pump 28 and the motor 9 are stopped and the solenoid valve 2 30 and the solenoid valve 3 32 are closed. The ozone inside the freeze-drying cabinet 1 can be extracted by using the vacuum pump 4, and then the camellia chrysantha is freeze-dried and formed according to the operating steps of Example 1. Then, by first sterilizing and disinfecting the camellia chrysantha and then freeze-drying and forming the camellia chrysantha, the quality of the freeze-dried camellia chrysantha is further improved.
