Abstract
Description
Technical Field
[0001] This invention relates to research equipment for agricultural product preservation, and in particular to a research and observation device for agricultural product preservation used in academic research. Background Technology
[0002] Agricultural product preservation is a core issue in agriculture, food science, and logistics, and it is of great significance for reducing post-harvest losses, ensuring food security, and increasing the added value of agricultural products. In study tours, agricultural product preservation, as a comprehensive practical theme integrating biology, chemistry, physics, and environmental science, has become an important vehicle for cultivating students' scientific inquiry abilities, practical skills, and innovative thinking.
[0003] Currently, primary and secondary schools and research bases generally use the storage comparison method for related observational studies. This involves placing the same agricultural product sample in different common environments (such as room temperature, refrigeration, and sealed bags), and manually observing changes in color, shape, and texture at regular intervals, while recording the spoilage time. Although this method is simple and easy to implement, it has the following significant shortcomings:
[0004] Uncontrollable environment: It is impossible to accurately measure and stably control key parameters such as temperature, humidity, and gas composition. The environment fluctuates greatly, and the experimental results are easily affected by external interference, resulting in insufficient scientific rigor.
[0005] The data is highly subjective: it relies on visual observation and textual description, lacks objective and quantitative data support (such as temperature, humidity, CO2 concentration, etc.), and is difficult to conduct in-depth analysis and comparison.
[0006] The process is not intuitive: the corruption process is slow, making it difficult for students to observe continuously within the limited study period. They are likely to miss key changes and lack continuous perception and recording of the process.
[0007] While specialized research equipment can provide more precise environmental control and data recording, its high cost and operational complexity make it unsuitable for research and study scenarios. Therefore, there is an urgent need for a research device that is moderately priced, easy to operate, and capable of multivariate control to support students in conducting controlled comparative experiments, automatically recording data and images throughout the process, thereby shifting the focus of research and study from operational recording to scientific thinking and data analysis, effectively improving the quality and effectiveness of research and study.

[0030] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0032] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0033] like Figures 1-6The device shown is an agricultural product preservation observation and research device for research purposes, including a support frame 1, on which a plurality of storage compartments 11 are arranged in an array.
[0034] An adjustment system 2 is also installed on the support frame, such as Figure 1 As shown, the control system consists of a CO2 concentration control component 21, a humidity control component 22, and a temperature control component 23. It should be noted that the CO2 concentration control component 21, humidity control component 22, and temperature control component 23 can extend to each storage cell 11 on the support frame to control the experimental variables of the observation box system 3 placed in the storage cell 11.
[0035] It should be noted that in this solution, the observation box system 3 is an independent research and observation environment, and can be detachably placed in the storage compartment 11. It should also be understood that the observation box system 3 is connected to the CO2 concentration regulating component 21, humidity regulating component 22, and temperature regulating component 23 in the regulating system 2, so that the environmental data in each observation box system can be flexibly adjusted through the regulating system.
[0036] It is important to know that, such as Figures 2-5As shown, the observation box system 3 in this scheme includes a box body 31 and a sealing cover 32. The sealing cover 32 is sealed and installed on the box body 31 to form a closed observation chamber for observing changes in the state of agricultural products. Simultaneously, a set of measuring components 33 is also provided on the box body 31, including measuring instruments capable of measuring CO2 concentration, humidity, and temperature. It should be noted that the measuring components are inserted into the box body, and the measuring head extends into the observation chamber formed by the box body 31 and the sealing cover 32 to measure changes in various environmental data within the observation chamber in real time. To meet the needs of research and study, i.e., to observe the preservation state of agricultural products under various environments, thus generating systematic and effective data for research and study, the sealing cover 32 is provided with adjustment channels A32a, B32b, C32c, and an exhaust channel 32d. Among them, adjustment channel A is connected to the CO2 concentration adjustment component 21, enabling the adjustment system to deliver stable CO2 into the observation chamber, thereby controlling the CO2 concentration in the observation chamber. Simultaneously, the regulating channel B32B is connected to the humidity regulating component 22, enabling the regulating system 2 to stably replenish air with a certain humidity level into the observation cavity through the humidity regulating channel B, thereby maintaining the air humidity in the observation cavity. The regulating channel C is connected to the temperature regulating component 23, through which the regulating system 2 inputs stable temperature-controlled air (hot or cold air) into the observation cavity, thereby maintaining a constant temperature in the observation cavity. It should be noted that due to dynamic environmental changes, maintaining stability in the observation cavity requires the regulating system to implement adaptive dynamic adjustments. Therefore, the measuring component 33 in this scheme is electrically connected to the CO2 concentration regulating component 21, the humidity regulating component 22, and the temperature regulating component 23 in the regulating system 2, thereby establishing a feedback system to achieve dynamic adjustment of the environment in the observation cavity.
[0037] It is important to know that agricultural products can spoil during the research and observation process. To prevent pollutants from spoiled agricultural products from entering the control system or the environment, filter elements 34 are installed in control channels A32a, B32b, C32c, and exhaust channel 32d to filter the passing air.
[0038] Furthermore, it should be noted that during the research process, it may be found that the regulating media directly introduced into the observation chamber through regulating channels A, B, and C may cause environmental disturbances within the observation chamber. Specifically, the temperature, CO2 concentration, and humidity within the observation chamber may become uneven, affecting the accuracy of the data collected on agricultural product preservation. Therefore, an air chamber 35 is provided on the inner side of the sealing cover 32, enclosing regulating channels A, B, and C. When the regulating substance is sprayed out through the corresponding regulating channel, it is first mixed within the air chamber 35, then evenly enters the observation chamber through the filter ring 36 located on the side wall of the air chamber, and is then evenly discharged into the observation chamber through the air holes 35a on the side wall of the air chamber, thereby reducing environmental disturbances caused by direct injection of the regulating media. It is important to note that to ensure the cleanliness of the air chamber and prevent harmful substances generated on agricultural products that have undergone changes in state (spoilage) from entering and contaminating the air chamber during the agricultural product preservation research, [further measures are taken]. A filter ring 36 is also fitted around the outside of the air chamber, covering the air vents on the air chamber so that the air entering and exiting the air chamber is filtered by the filter ring. Furthermore, it should be noted that the air chamber in this design can also cover the exhaust passage to filter the exhaust gas discharged from the observation chamber. However, to prevent the exhaust gas from mixing with the introduced regulating medium, a partition plate 35b is also provided in the air chamber, dividing the air chamber into an inlet chamber 35c and an outlet chamber 35d. The inlet chamber covers regulating channels A, B, and C, while the outlet chamber covers the exhaust passage.
[0039] Additionally, it should be noted that during the research and study of agricultural product preservation, it is necessary to observe changes in the condition of the agricultural products in real time and make relevant records. Specifically, an observation mirror 37 is also installed in the middle of the sealed lid. Figure 6 As shown, the air chamber 35 is positioned away from the observation mirror so that researchers can observe the real-time changes of the agricultural products inside the observation chamber through the lens. However, it should be noted that the changes in the state of agricultural products during preservation research are a continuous process, and researchers obviously cannot record continuously for extended periods. Therefore, a camera mount 38 is installed on the outer surface of the sealing cover, on which a camera 39 is detachably mounted. This camera is positioned directly above the agricultural products placed in the observation chamber through the observation mirror 37 to continuously record the changes in the state of the agricultural products.
[0040] Additionally, it's important to understand that agricultural products located in the observation chamber are susceptible to contamination due to changes in their moisture content. High-moisture products, in particular, will generate significant amounts of pollutants, contaminating the inner surface of the container. To prevent this, an isolation bag 310 is placed within the observation chamber. This bag fits snugly against the inner wall of the chamber, and its edge extends outwards before being covered by a sealing cap. Several sealing rings 311 are also present on the isolation bag. A measuring instrument on the measuring component 33 is inserted into the isolation bag through these sealing rings to provide real-time environmental measurements. The sealing rings are secured to the measuring component to prevent contaminants from entering the observation chamber through them. Furthermore, the isolation bag's edge extends outwards from the observation chamber and is then covered by the sealing cap.
[0041] Additionally, it should be noted that to prevent the waste liquid produced by spoiled agricultural products from flowing towards the sealing cap and thus contaminating its inner surface, at least one support point is provided at the bottom of the container. This support point, located near the sealing cap, raises the opening of the container, ensuring that the waste liquid from spoiled agricultural products flows towards the bottom of the isolation bag.
[0042] In addition, to ensure the stability of the isolation bag in the observation chamber when it is in an open state, four magnetic strips 312 are provided in the isolation bag 310. These magnetic strips are attached to the four corners of the inner wall of the box to open the isolation bag into a cuboid structure.
[0043] It should also be noted that a controller 313 is also installed on the sealing cover 32. The controller has a display screen and Bluetooth function. The controller 313 has a setting button and is connected to the measuring component and the adjustment system 2 via Bluetooth. After collecting the measurement data (CO2 concentration, depth, temperature) transmitted by the measuring component, the controller adjusts the opening degree of the corresponding solenoid valves A, B, and C to maintain the stability of the environment in the observation chamber.
[0044] It should be noted that in this solution, the CO2 concentration regulating component 21 includes a CO2 storage tank 21d and a pipe A21a connected to the outlet of the CO2 storage tank 21d. Pipe A21a has branch pipes A21b extending to each storage compartment 11. Branch pipes A21b are detachably connected to the regulating channel A32a, and each branch pipe A21b is equipped with a solenoid valve A21c electrically connected to the controller 313. The humidity regulating component 22 includes a humidifier 22d, the outlet of which is connected to a pipe B22a. Pipe B22a has branch pipes B21c extending to each storage compartment 11. 2b, the branch pipe B22b is detachably connected to the regulating channel B32b, and the branch pipe B22b is provided with a solenoid valve B22c electrically connected to the controller 313; the temperature regulating component 23 includes multiple sets of temperature-regulating air conditioners 23d and multiple pipes C23a, the multiple pipes C23a are connected to the corresponding temperature-regulating air conditioners 23d to form an independent temperature-regulating pipe network, the pipes C23a are provided with branch pipes C23b extending to each storage cell 11, the branch pipes C23b are detachably connected to the regulating channel C32c, and the branch pipes C23b are provided with a solenoid valve C23c electrically connected to the controller 313.
[0045] Working Principle: During agricultural product preservation research activities, participants place the agricultural products to be studied in isolation bags within the storage chamber. The sealing cap is then placed on the chamber. After preparation, the participants place the chamber in the corresponding storage compartment and connect the CO2 concentration regulating component 21, humidity regulating component 22, and temperature regulating component 23 to regulating channels A, B, and C of the observation chamber system. Subsequently, via Bluetooth connection technology, the corresponding solenoid valves A, B, and C in the CO2 concentration regulating component 21, humidity regulating component 22, and temperature regulating component 23 are connected. During the agricultural product preservation research project, the controller adjusts the opening degree of the connected solenoid valves A, B, and C to maintain the environment in the observation chamber at the required CO2 concentration, humidity, and temperature values. It should be noted that agricultural product preservation research is a continuous process, and participants obviously cannot maintain continuous attention and may easily miss relevant phenomena. Therefore, a set of cameras installed outside the sealed cover can continuously record the agricultural products in the observation chamber, which facilitates subsequent data recording and status recording.
