Abstract
Description
Technical Field
[0001] This utility model relates to the field of fruit and vegetable precooling and pathological treatment technology, specifically to a fruit and vegetable precooling and synergistic physiological and pathological treatment equipment. Background Technology
[0002] Differential pressure precooling chambers use high-pressure fans to supply air into the chamber. The principle of differential pressure precooling is to create a pressure difference between the two sides of the packaging box using a high-pressure fan (differential pressure fan), forcing cold air into the chamber through ventilation holes on the packaging box. This allows for direct heat exchange with the surface of the product being precooled, achieving rapid and uniform cooling. The advantages of differential pressure precooling include fast precooling speed, good effect, energy saving, and benefits for fruit and vegetable preservation. Fruits and vegetables that have undergone precooling have extremely low water loss rates, maintaining optimal freshness.
[0003] Currently, differential pressure precooling boxes have limited functionality compared to existing fruit and vegetable precooling equipment. There are still physiological and pathological issues with fruit and vegetable precooling. If fruits and vegetables carry bacteria, they are prone to spoilage during the later preservation process, affecting their quality. Furthermore, the air delivery of the high-pressure fan in the differential pressure precooling box is limited by the size and position of the air outlet, resulting in a small range of cold air circulation and uneven precooling. Utility Model Content

[0021] like Figures 1 to 3As shown, the fruit and vegetable precooling and physiological pathological treatment equipment of this embodiment includes a precooling box 1, a treatment box 2 on one side of the precooling box 1, a door on one side of the precooling box 1 connected by a hinge, an air inlet box 3 on the side of the treatment box 2 away from the precooling box 1, a cold air inlet on the upper side of the air inlet box 3, a high-pressure fan 4 on the upper part of the inner side of the air inlet box 3, an air guide mechanism inside the air inlet box 3 below the high-pressure fan 4, an air outlet 5 between the air inlet box 3 and the treatment box 2, the air outlet 5 consisting of several evenly distributed ventilation holes, an air inlet 6 between the treatment box 2 and the precooling box 1, the air inlet 6 being a single, interconnected air outlet, and an air outlet 7 on the side of the precooling box 1 away from the treatment box 2, the air outlet 7 having several exhaust fans inside. The processing box 2 is equipped with a titanium dioxide photocatalytic module 9. An ultraviolet lamp 10 is located inside the processing box 2 near the air outlet 5. An atomizing tube 8 is located inside the processing box 2 near the air inlet 6. An atomizing nozzle 81 is mounted on the atomizing tube 8, which is connected to the atomization system. This achieves pressure differential precooling, atomized humidification, and antibacterial sterilization in the precooling box 1, preventing skin shrinkage. The titanium dioxide photocatalysis and atomization constitute a dual-level physiological and pathological regulation, achieving synergistic treatment of physiological and pathological processes during precooling, providing excellent quality assurance for subsequent fruit and vegetable preservation and processing. The high-pressure blower 4 ensures uniform airflow throughout the precooling box 1, resulting in uniform precooling within the large space of the precooling box 1.
[0022] Specifically, the air guiding mechanism includes a dispersing air guide plate 31, an air supply plate 32, and a concentrating air guide plate 33. The dispersing air guide plate 31 is installed in the air inlet box 3 below the high-pressure blower 4. The dispersing air guide plate 31 is located on the side near the air supply port 5. The air supply plate 32 is installed inside the air inlet box 3 on the side away from the air supply port 5 below the dispersing air guide plate 31. The concentrating air guide plate 33 is located in the middle of the inner side of the air inlet box 3. The cold air is partially dispersed by the dispersing air guide plate 31 in the air inlet box 3. Part of the dispersed cold air enters the processing box 2 through the air supply port 5, and part of it continues to flow along the air inlet box 3. During the flow, the cold air gradually disperses. The dispersed airflow is guided by the air supply plate 32 and approaches the air supply port 5. When the cold air flows through the concentrating air guide plate 33, the guided airflow is concentrated to form a concentrated airflow that continues to flow in the air inlet box 3. The concentrated airflow gradually disperses again during the flow. Thus, the air outlet of the high-pressure blower 4 is guided and processed by the dispersing air guide plate 31, the air supply plate 32, and the concentrating air guide plate 33 in the air inlet box 3.
[0023] Furthermore, the atomization system includes a connecting pipe 82, an atomizing pump 83, and an atomizing storage tank 84. The top of the precooling box 1 is equipped with an atomizing pump 83 and an atomizing storage tank 84. The atomizing pipe 8 is connected to the output end of the atomizing pump 83 through the connecting pipe 82, and the input end of the atomizing pump 83 is connected to the atomizing storage tank 84 through the connecting pipe 82. The atomizing storage tank 84 includes a 1-MCP storage tank and an antibacterial agent storage tank. There are two connecting pipes 82, two atomizing pumps 83, and two atomizing pipes 8. The two atomizing pumps 83 and the two atomizing pipes 8 atomize the 1-MCP storage tank and the antibacterial agent storage tank, respectively. Under the action of the atomizing pump 83, the 1-MCP in the 1-MCP storage tank is atomized into the processing box 2 through the atomizing nozzle 81 on the atomizing pipe 8, and the antibacterial agent in the antibacterial agent storage tank is atomized into the processing box 2 through the atomizing nozzle 81 on the atomizing pipe 8.
[0024] Furthermore, the atomizing nozzles 81 are positioned facing the air inlet 6, and several atomizing nozzles 81 are evenly spaced. The atomizing nozzles 81 atomize towards the air inlet 6, and the atomization is consistent with the direction of cold air inlet flow, thus accelerating the circulation of cold air.
[0025] Furthermore, the air supply outlet 5, air inlet 6, and air outlet 7 are set at corresponding heights to ensure that the cold air flows evenly among them. The air outlet 7 is equipped with a dustproof screen to prevent dust from entering.
[0026] Furthermore, the precooling box 1, the processing box 2, and the air inlet box 3 are all made of stainless steel, and the precooling box 1, the processing box 2, and the air inlet box 3 have high structural strength. The inner walls of the precooling box 1, the processing box 2, and the air inlet box 3 are all equipped with a heat insulation layer, which is a foam heat insulation layer, and the precooling box 1, the processing box 2, and the air inlet box 3 have good heat insulation performance.
[0027] Furthermore, the precooling box 1 is equipped with a support plate 12 inside, and a packaging box 11 is provided inside the precooling box 1. The packaging box 11 has gaps. Multiple layers of packaging boxes 11 are placed inside the precooling box 1. The gaps on the packaging boxes 11 are evenly distributed. The packaging boxes 11 are precooled evenly by pressure difference inside the precooling box 1.
[0028] The method of use in this embodiment is as follows: Fruits and vegetables are packed into a packaging box 11 with gaps. The packaging box 11 is placed inside the pre-cooling box 1. The door of the pre-cooling box 1 is closed. The cold air inlet of the air inlet box 3 is connected to the cold air source through a duct. Under the action of the high-pressure blower 4, the cold air source enters the interior of the air inlet box 3 through the high-pressure blower 4. Part of the cold air at the outlet of the high-pressure blower 4 is dispersed in the air inlet box 3 by the dispersion guide plate 31. Part of the dispersed cold air enters the processing box 2 through the air outlet 5, and part continues to circulate along the air inlet box 3. During the circulation process, the cold air gradually disperses, and the dispersed airflow is guided by the air outlet plate 32 to approach the air outlet. 5. When the cold air flows through the centralized air guide plate 33, the airflow is concentrated and continuously flows within the air inlet box 3. During this concentrated airflow, it gradually disperses again, thus guiding the air outlet of the high-pressure blower 4 through the dispersing air guide plate 31, the air supply plate 32, and the centralized air guide plate 33 within the air inlet box 3. This ensures that the air outlet of the high-pressure blower 4 can enter the processing box 2 uniformly from the air outlet 5 over a wide area. The cold air flows evenly through the processing box 2 and enters the pre-cooling box 1 uniformly from the air inlet 6. During the flow of the cold air through the processing box 2, the titanium dioxide photocatalytic module 9, composed of nano-titanium dioxide coatings, generates its own... Free radicals and electron holes, along with the cold air flow, enter the pre-cooling chamber 1. Under the action of the atomizing pump 83, 1-MCP from the 1-MCP storage tank is atomized into the processing chamber 2 through the atomizing nozzle 81 on the atomizing pipe 8. Similarly, the antibacterial agent from the antibacterial agent storage tank is atomized into the processing chamber 2 through the atomizing nozzle 81 on the atomizing pipe 8. Free radicals, electron holes, 1-MCP, and the antibacterial agent enter the pre-cooling chamber 1 in a wide and uniform manner from the air inlet 6 through the cold air. The cold air flows through the pre-cooling chamber 1 and exits from the air outlet 7, achieving pressure differential pre-cooling, atomized humidification, and antibacterial sterilization in the pre-cooling chamber 1, preventing skin wrinkling. The high-pressure fan 4 forces cold air to circulate through the pre-cooling box 1 and penetrate the pores of the packaging box 11 to achieve rapid cooling at a wind speed of 2-4 m / s. On the other hand, 1-MCP and antibacterial agents can be atomized and humidified to achieve simultaneous treatment of endogenous ethylene antagonism and disease control. The titanium dioxide photocatalytic module 9 is a nano-titanium dioxide coating that generates free radicals and electron holes under ultraviolet light excitation to decompose exogenous ethylene in the environment. At the same time, electrons can also kill bacteria. Together with atomization, it constitutes a two-level physiological and pathological regulation, realizing the synergistic treatment of physiological and pathological processes in the pre-cooling process, and providing good quality assurance for the subsequent preservation and processing of fruits and vegetables.
[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
