[0017] As Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a fresh-keeping and refrigeration system for agricultural products includes an enclosed heat-insulating storage body 1 composed of heat-insulating boards, an antibacterial electromagnetic field device 2 arranged in the storage body 1, a constant temperature control system, a constant humidity control system, an intelligent total control system, and a temperature and humidity detection probe 3.
[0018] The heat-insulating storage body 1 is composed of a composite heat-insulating wall 11 arranged around, an anti-electric field leakage shielding layer, and a cargo entrance and exit 12, forming an enclosed heat-insulating space. The composite heat-insulating wall 11 ensures the good heat-insulating performance of the storage body, and the anti-electric field leakage shielding layer is used to prevent the electromagnetic radiation that may be generated by the antibacterial electromagnetic field device 2 from leaking. The cargo entrance and exit 12 is provided with a heat-insulating sliding door 13 to reduce the heat loss when opening the door. A power-off device 14 is also provided at the cargo entrance and exit 12, which is mechanically linked with the heat-insulating sliding door 13 to ensure that the power supply of the antibacterial electromagnetic field device 2 is automatically cut off when opening the door, improving safety.
[0019] The antibacterial electromagnetic field device 2 includes a frequency modulation power supply device and distributed electric field enhancement emission units 4, which inhibit the growth of bacteria by generating electromagnetic fields of specific frequencies. The frequency modulation power supply device is electrically connected to the electric field enhancement emission unit 4, provides electrical energy for the electric field enhancement emission unit 4, and optimizes the antibacterial effect of the electromagnetic field by adjusting the frequency. The electromagnetic field acts on the surface of the eggs, can effectively inhibit the growth of bacteria, and extend the freshness preservation period.
[0020] The constant temperature control system includes a refrigeration unit 5 and a gentle air duct 6. The gentle air duct 6 is arranged at the top of the heat preservation chamber body 1. The refrigeration unit 5 is communicated with the gentle air duct 6, and realizes the uniform distribution and precise control of the cold air in the chamber by slightly circulating the air.
[0021] The constant humidity control system includes a humidifying device 7, which is also placed at the top of the heat preservation chamber body 1 and is adjusted according to the humidity in the chamber to maintain a suitable humidity environment.
[0022] The temperature and humidity detection probe 3 includes an in-chamber environment temperature sensor and an in-chamber environment humidity sensor, which are arrayed on the side wall of the chamber body and are used to comprehensively monitor the changes in the in-chamber environment.
[0023] The intelligent control system includes an embedded control main board, a touch screen operation interface 8 and an electric field signal indicator light 81. The touch screen operation interface 8 provides a temperature parameter setting module and a real-time monitoring and display module. Users can conveniently set and adjust system parameters, and at the same time, real-time monitor the in-chamber environment and product status. The electric field signal indicator light 81 is used to indicate the working state of the antibacterial electromagnetic field device 2.
[0024] The working process of this system is as follows: The eggs are packed in boxes and stacked neatly and placed into the heat preservation chamber body 1. The heat preservation translation door 13 at the goods entrance and exit 12 is closed, and the power disconnecting device 14 is in the on state. Open the touch screen operation interface 8 of the intelligent total control system, enter the temperature parameter setting module, input the temperature and humidity parameters for egg freshness preservation, and then click start to work. The intelligent total control system issues an instruction, and the refrigeration unit 5 starts to work. Through the gentle air duct 6 for cold air exchange, the cold air is evenly transported into the heat preservation chamber body 1, quickly reducing the temperature inside the eggs until the set temperature value is reached; at the same time, the frequency modulation power supply device supplies power to the electric field emission unit, generates a high-energy electromagnetic field harmless to the human body, and radiates it throughout the chamber body to inhibit the growth and reproduction of bacteria. Under the action of the electromagnetic field, the egg liquid is kept activated, making the eggs and egg liquid in a fresh state and maintaining their original characteristics. The intelligent control system displays the temperature and humidity data monitored by the temperature and humidity detection probe 3 and the working states of the refrigeration unit 5 and the humidifying device 7 on the touch screen operation interface 8. At this time, the electric field signal indicator light 81 is on, indicating that the electromagnetic field in the chamber meets the requirements, and the freshness preservation and refrigeration system enters the normal working state. When the temperature and humidity in the heat preservation chamber body 1 reach the temperature and humidity of the refrigerated goods, the intelligent control system respectively issues working instructions to stop the refrigeration unit 5 and the humidifying device 7 from working.
[0025] In the constant temperature control system of this system, the fluctuation range of the refrigeration temperature is ±1.5°C, and the fluctuation range of the humidity value of the humidification device 7 in the constant humidity control system is ±3%. When the set value is exceeded, the intelligent control system issues a stop or working instruction to accurately control the temperature and humidity in the thermal insulation chamber 1 to meet the set requirements.
[0026] The fresh-keeping and refrigeration system provided by the present invention is equipped with constant temperature and humidity equipment. By setting the detection probe, the temperature and humidity are accurately adjusted to keep the temperature and humidity in the cold storage meeting the requirements for the fresh-keeping storage of agricultural products. Under the action of the high-energy electromagnetic field force, the water molecules in the egg liquid of agricultural products such as eggs are activated, and do not solidify and freeze at -4°C, thus further reducing the fresh-keeping storage temperature of eggs and egg liquid. At low temperatures, the metabolic rate of egg cells in eggs changes much slower. Eggs can be stored fresh at -2°C (the egg liquid remains in a liquid state) for more than 300 days and all performance indicators meet the standards (the storage period in an ordinary cold storage is within 30 days). The eggs maintain their original appearance and color, without reducing the appearance of the commodity. The eggs and egg liquid are in a fresh state and maintain their original nutritional components and taste. The device of this system has low energy consumption, is economical and practical, and has broad market application prospects.
[0027] The above embodiments are the preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of this technical solution is within the scope of this invention patent.
[0028] In order to make it more convenient for those of ordinary skill in the art to understand the improvements of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified, and for the sake of clarity, some other elements have also been omitted in this application document. Those of ordinary skill in the art should be aware that these omitted elements can also constitute the content of the present invention.
