[0040] The nitrogen air drying device 111 is fixedly mounted on the first conveying mechanism 110 and is used for drying fruits and vegetables;

[0041] An intelligent conveyor belt 114 is provided on one side of the first conveying mechanism 110 and is used to uniformly convey fruits and vegetables.

[0044] : The first hoist 106 can be an automatic opening and closing hoist following the water flow, and the second hoist 109 can be an automatic closing hoist;

[0045] The second conveying mechanism 116 is located below the intelligent conveyor belt 114 near the photoelectric intelligent sorting device 115 and is used to convey the inferior fruits;

[0046] The area between the second elevator 109 and the first conveying mechanism 110 is the first sealed nitrogen-filled sterile area 112. The area formed by the intelligent conveyor belt 114, the second conveying mechanism 116, and the third conveying mechanism 117 is the second sealed nitrogen-filled sterile area 122. Two sets of symmetrically arranged diverter guide plates 113 are installed at the end of the upper surface of the second elevator 109, and the conveying guide ports of the two sets of diverter guide plates 113 correspond to the two rows of mechanical separators on the intelligent conveyor belt 114.

[0047] The intelligent conveyor belt 114 is mechanically blocked by a flap near the mechanical separator and can be flexibly closed or opened to flexibly place fruits and vegetables on the second conveying mechanism 116 or the third conveying mechanism 117.

[0048] In this embodiment, the fully automated fruit and vegetable food processing and packaging line, when in use, the visual recognition module on the mechanical gripper 102, through algorithms such as YOLO, SSD, recognizes the outline of the apple frame, the handle if any, or feature points, and determines its three-dimensional coordinates X, Y, Z and angle in the coordinate system of the first mechanical arm 101. The first mechanical arm 101 moves from the initial position to the top of the apple frame, adjusts its posture according to the coordinates located by the visual recognition module, ensures that the mechanical gripper 102 is aligned with the grasping point of the frame, and the mechanical gripper 102 slowly closes and clamps. The frame is slightly lifted after being grabbed, and the first robotic arm 101 carries the frame along a preset path to the dumping starting position above the bubble cleaning pool 103. The first robotic arm 101 adjusts the angle of the frame by rotating joints such as the wrist and elbow, so that the frame opening faces the inside of the bubble cleaning pool 103, and gradually tilts it to ensure that the apple can slide down by gravity and fall into the bubble cleaning pool 103. After the dumping is completed, the first robotic arm 101 resets the empty frame, moves it to the empty frame storage area and puts it down. The first robotic arm 101 returns to the initial position and waits for the next task;

[0049] Since there is water inside the bubble cleaning pool 103, the fruit and vegetable apple will not be damaged if it falls into the water;

[0050] At the same time, the pump body is started to continuously extract part of the water in the bubble cleaning pool 103 through the liquid guide tube (not shown in the figure), and at the same time, it is transported to the stamping nozzle 104 and discharged through the drainage port of the stamping nozzle 104. The impact force of the water flow of the stamping nozzle 104 can be used as an auxiliary power to push the apples to continue to move toward one end of the bubble cleaning pool 103 to prevent the apples from piling up at the entrance. At the same time, the water pump 201 is started to extract the water in the bubble cleaning pool 103 through the connecting pipe 202 and transport it to the delivery pipe 203. The water is discharged into the flushing pipe 204 through the delivery pipe 203 and discharged through the flushing pipe 204. The water flow sprayed from the flushing pipe 204 is usually pressure-regulated and will directly impact the apples that have just entered the bubble cleaning pool 103. The kinetic energy of the water flow will flush away dirt such as mud, dust, and residual pesticides attached to the surface of the apples. In particular, for the wrinkles and depressions on the apple skin, relying solely on the stirring of bubbles may not be thorough. The water flow impact can strengthen the cleaning of these areas in a targeted manner.

[0051] During the pumping process, the water inside the bubble cleaning pool 103 is used to achieve water recycling, saving a certain amount of water resources. At the same time, the filter screens installed on the connecting pipe 202 and the liquid guide pipe can filter the sewage and cement inside the bubble cleaning pool 103 to avoid blockage, thereby further improving the use effect of this structure.

[0052] The bubble cleaning tank 103 is equipped with an aeration system on both sides. Air is continuously injected into the water in the tank through an air compressor or air pump, generating a large number of dense bubbles. These bubbles will form multiple cleaning forces during the rise and burst process, further improving the cleaning of apples.

[0053] At the same time, by starting the motor, a group of brush cleaning mechanisms 105 rotates, and the multiple groups of brush cleaning mechanisms 105 drive the multiple groups of brush cleaning mechanisms 105 to rotate under the action of the sprocket and chain. The brushes on the surface of the brush cleaning mechanism 105 are usually made of food-grade nylon, which is soft and tough. They are in direct contact with the surface of the apple, and the rotational motion generates friction. This friction can effectively peel off stubborn impurities that are difficult to remove with bubbles. The hardness of the brush cleaning mechanism 105 and the motor speed are optimized, such as a speed of 50-150 rpm, which can generate sufficient friction to remove dirt without scratching the apple skin, thereby achieving the dual effects of cleaning and protecting the apple.

[0054] After being cleaned by the impact of bubbles and friction of brushes in the bubble cleaning pool 103, the apples are gradually gathered towards the first elevator 106 at the end of the bubble cleaning pool 103 under the continuous push of the water flow in the pool, in preparation for entering the first elevator 106. By starting the servo motor and driving the active roller to rotate through the chain / gear transmission, the conveyor belt is driven to circulate. The cleaned apples are naturally flowed to the lower end feed port of the trapezoidal elevator under the push of the water flow in the bubble cleaning pool 103. The conveyor belt is in a continuous low-speed operation state, and the motor drives the conveyor belt to run upward in an inclined direction. At this time, the apples are acted upon by two forces: since the friction force of the conveyor belt is greater than the gravity component, the material moves upward synchronously with the conveyor belt. During the lifting process, the mesh structure of the conveyor belt allows the moisture and impurities remaining on the surface of the material to leak back into the bubble cleaning pool 103, reducing the amount of water brought into the ozone pool 107.

[0055] It should be noted that the first elevator 106 can be an elevator that automatically opens and closes with the water flow. The bearing component of the first elevator 106 is in an "open" state due to the impact of the water flow, flush with the bottom of the bubble cleaning pool 103, and receives the apples. The thrust of the water flow and the gravity of the apples trigger the bearing component to flip upward around the axis to achieve closure, and then rise along an inclined trajectory. With the help of the water level difference, the conveying is assisted. When it rises to the highest point and connects with the ozone pool 107, the bearing component automatically resets and opens, and the apples slide into the ozone pool 107 by gravity, completing the transfer.

[0056] The ozone generator box 108 continuously introduces ozone into the ozone tank 107 through a pipe to form ozone water. After soaking in the tank for a certain period of time, the ozone kills bacteria, viruses and other microorganisms on the surface of the apples through oxidation. The disinfected apples are collected to the lower end feeding area of ​​the second elevator 109 under the action of water flow or self-weight in the ozone tank 107. The feeding end of the second elevator 109 is connected to the bottom of the ozone tank 107 to ensure that the apples can enter naturally. At this time, the supporting component of the second elevator 109, which can be a closed hopper, is in the process of being opened. In the open state, it is waiting to receive apples. When the apples enter the feeding area and accumulate to a certain amount, the sensing device will be triggered, and the drive system of the second elevator 109, such as the motor, will start, the carrying component will automatically close, and the hopper will flip and snap together, wrapping the apples in a closed space. When the carrying component rises to the first conveying mechanism 110, the drive system will trigger the opening command, and the carrying component will automatically open. The apples will leave the second elevator 109 under the action of gravity, and enter its first sealed nitrogen-filled sterile area 112 and be arranged side by side on the first conveying mechanism 110;

[0057] The first sealed nitrogen-filled sterile area 112 is a closed cavity that can be enclosed by stainless steel or food-grade plastic. Only an opening for apples to enter and exit is retained, and a soft sealing curtain is provided at the opening to reduce nitrogen leakage. High-purity nitrogen with a purity of ≥99.9% is continuously introduced into the cavity. The pressure is balanced through the exhaust port, and the original air in the cavity is gradually replaced to reduce the oxygen concentration in the cavity to below 0.5%, forming a sterile, low-oxygen environment. Nitrogen is an inert gas that does not react with apples and can inhibit the survival and reproduction of microorganisms. The low-oxygen environment also delays the oxidative browning of apples and keeps the peel Color, nitrogen air drying equipment 111 pressurizes the nitrogen in the cavity, and forms a high-speed directional airflow through the nozzles distributed above the first conveying mechanism 110 and on the nitrogen air drying equipment 111. The airflow blows directly to the surface of the apple, and uses the "airflow shear force" to quickly remove the residual moisture after ozone disinfection. The apple moves with the first conveying mechanism 110 in the first sealed nitrogen-filled sterile area 112 of the sealed cavity. After 10-30 seconds of nitrogen purge, the surface moisture is completely evaporated and reaches a dry state. The apple is removed from the outlet at the other end of the sealed area and enters the next process;

[0058] During this process, when the apples come out of the sealed area, they will contact the two sets of diversion guide plates 113. Due to the obstruction and guidance of the diversion guide plates 113, the movement direction of the apples will be changed. At the same time, the first conveying mechanism 110 moves along the inclined direction of the diversion guide plates 113, allowing the apples to fall accurately one by one into the separators on the intelligent conveyor belt 114, facilitating subsequent detection by the photoelectric intelligent sorting equipment 115.

[0059] Apples are placed one by one onto the separators of the intelligent conveyor belt 114. The separators are arc-shaped grooves and move synchronously with the conveyor belt 114. The spacing between the separators matches the size of the apples to prevent adjacent apples from interfering with detection. The intelligent conveyor belt 114 then carries the apples through the photoelectric intelligent sorting equipment 115. The photoelectric intelligent sorting equipment 115 consists of multiple sets of sensors, cameras, and light sources. A high-resolution industrial camera captures images of the apple surface, which are then combined with an LED strobe light source to eliminate shadows. An image recognition algorithm is used to analyze the presence of defects such as spots, bruises, insect holes, and cracks. Photoelectric sensors, such as infrared sensors, detect the color uniformity of the apples, such as to determine maturity, and remove abnormal colors such as those that are too green, too red, or partially browned. A laser profile sensor scans the three-dimensional dimensions of the apples, calculating parameters such as diameter and circumference. These are compared with preset standards to screen out oversized, undersized, or deformed apples. A near-infrared spectroscopy sensor penetrates the peel to analyze indicators such as sugar content and acidity to assist in determining internal quality. The detection data is transmitted to the control system in real time. The algorithm comprehensively scores each apple based on its appearance, size, and internal quality, determining whether it is a good or bad apple.

[0060] When the apples determined to be defective move to the diversion area along the separator, the actuator is activated to transfer them to the second conveyor mechanism 116 below the intelligent conveyor belt 114. The control system locates the real-time position of the defective apples. When they reach the diversion point, the pneumatic push rod at the corresponding position is triggered to quickly extend and push from the bottom, releasing the flap at the bottom of the separator, leaving the bottom open. The apples then break away from the separator and fall onto the second conveyor mechanism 116, where they are transported to the defective collection area for collection.

[0061] The high-quality apples that meet the quality requirements continue to move toward the end along the intelligent conveyor belt 114. The control system plans the destination of each apple to the third conveyor mechanism 117 in advance according to the grade of the high-quality apples, such as grade one or grade two.

[0062] By setting up the second sealed nitrogen-filled sterile area 122, high-purity nitrogen is continuously introduced into the entire dotted area, and the air in the area is simultaneously extracted to reduce the oxygen concentration in the area to below 0.1%, thereby forming a sterile, low-oxygen, positive-pressure environment.

[0063] During this process, the second robotic arm 118 uses the visual recognition module to identify the three-dimensional coordinates of the apple on the third conveying mechanism 117, and plans the shortest grasping path based on the load-bearing capacity of the vacuum suction nozzle plate 119. The vacuum suction nozzle plate 119 moves to the top of the apple, generates suction through the negative pressure system, and gently adsorbs the surface of the apple. The second robotic arm 118 carries the apple along the preset trajectory and accurately places it on the feeding station of the vacuum nitrogen packaging machine 120. Then the vacuum suction nozzle plate 119 releases the negative pressure to complete the placement. The vacuum nitrogen packaging machine 120 automatically conveys food-grade composite packaging film, such as PET / PE material, and makes the film into a concave tray through a forming mold. The second robotic arm 118 drives the vacuum suction nozzle plate 119 to drop the placed apple into the tray, and the positioning sensor ensures The apples are centered to avoid edge wrinkles during packaging. During this process, the sealed chamber of the vacuum nitrogen packaging machine 120 is closed, and the vacuum nitrogen generator 123 connected through the bottom pipe extracts the air in the packaging film to make the vacuum degree in the chamber reach above -0.09MPa to prevent the apples from oxidizing and deteriorating. After vacuuming, the vacuum nitrogen generator 123 simultaneously injects high-purity nitrogen into the package to fill the gaps between the apples to form an inert gas protective layer, inhibiting the growth of microorganisms and buffering collisions during transportation. The vacuum nitrogen packaging machine 120 heats and presses the edges of the packaging film to form an airtight package. The packaged apples are pushed to the fourth conveying mechanism 121 by the discharge port of the vacuum nitrogen packaging machine 120. The fourth conveying mechanism 121 conveys the packaged apples to the subsequent links outside the sealing area.

[0064] This solution, through innovative design, realizes the automation and intelligence of the fruit and vegetable food processing and packaging production line, greatly improving the efficiency of cleaning, sorting, packaging and other links, reducing quality fluctuations and resource waste caused by manual operations, ensuring food quality stability and safety, while significantly reducing labor costs and enhancing the company's market competitiveness and sustainable development capabilities.
