[0003] Currently, the existing traditional preservation methods for Zui plums generally include low-temperature refrigeration, modified atmosphere packaging, etc., which have certain limitations and require professional equipment and venues for preservation. When picking Zui plums, in order to maintain freshness, growers generally pick them at night. After that, when the cold chain vehicle arrives, the Zui plums are loaded and transported to a special storage place for preservation. This results in a certain time interval between the two. During this period, the Zui plums are generally stored at room temperature after being picked from the fruit trees, which is easily affected by the external environment, causing the picked Zui plums to be infected by microorganisms and their own metabolism to accelerate, resulting in a decline in quality and a shortening of the shelf life.

[0014] A usage method of a Prunus salicina Lindl. var. cordata J. Y. Zhang et al. preservation device based on hydrogen includes the following steps: Step 1: Before starting work, first tow the preservation device to the Prunus salicina Lindl. var. cordata J. Y. Zhang et al. orchard area by a vehicle and place it. Then, inject cleaning water flow into the cleaning module installed at the tail area of the equipment box, and supply power to each module of the preservation device through the circuit warehouse to turn it on. Step 2: Put the picked Prunus salicina Lindl. var. cordata J. Y. Zhang et al. into the cleaning tank opened at the upper rear side of the cleaning box from the feeding port. Then, turn on the circulating pump, the cleaning conveyor, and the conveying motor in sequence through the control box. Among them, the circulating pump can extract the water flow injected into the cleaning box and transport it to the flushing rack. Then, the nozzles arranged on the flushing rack flush the put Prunus salicina Lindl. var. cordata J. Y. Zhang et al. While flushing, the conveying motor will drive the cleaning conveyor to rotate under the action of the belt, and transport the flushed Prunus salicina Lindl. var. cordata J. Y. Zhang et al. forward until the end of the cleaning conveyor. Step 3: When the cleaning conveyor transports the Prunus salicina Lindl. var. cordata J. Y. Zhang et al. to the end, due to the change of the angle, the Prunus salicina Lindl. var. cordata J. Y. Zhang et al. will fall into the feeding hopper. Since the inside of the feeding hopper is inclined, the fallen Prunus salicina Lindl. var. cordata J. Y. Zhang et al. will enter the air-drying conveyor box along the slope, and the internal conveying structure will transport the Prunus salicina Lindl. var. cordata J. Y. Zhang et al. forward. During the conveying process, the intake fan will extract the external air to dry the surface of the passing Prunus salicina Lindl. var. cordata J. Y. Zhang et al. After the dried Prunus salicina Lindl. var. cordata J. Y. Zhang et al. reaches the end of the conveying structure, it will enter the inner inclined connection box for transfer, and then enter the feeding pipe connected to it along the internal inclination angle, so as to be transported into the equipment box for storage. Step 4: The Prunus salicina Lindl. var. cordata J. Y. Zhang et al. that enters the inside of the equipment box will first fall on the transfer cross plate. Then, the tilting motor drives the docking support block to rotate clockwise first, tilting one end of the transfer cross plate to the right first, so that the Prunus salicina Lindl. var. cordata J. Y. Zhang et al. that falls on the transfer cross plate is first transported to the right feeding belt. At the same time, the right feeding belt will transport the Prunus salicina Lindl. var. cordata J. Y. Zhang et al. that falls on the upper end to a higher place on the right, enter the feeding port of the right spiral storage module, and then roll down along the spiral storage tank until it stops at the position of the baffle near the discharge port. Then, when the inside of the right spiral storage module is almost full from the lower spiral to the upper spiral, change the inclination angle of the transfer module; Step 5: When the tilting angle of the material transfer module tilts to the left and contacts the left feeding belt, the Chinese quince on the transverse material transfer plate will be conveyed and stored in the internal spiral storage tank of the left spiral storage module for Chinese quince. Step 6: After the left and right spiral storage modules inside the equipment box are both full, close the sealing door, then turn on the hydrogen generation device, produce hydrogen by electrolyzing water, and transport the hydrogen into the equipment box, so that the stored Chinese quince is soaked in a hydrogen environment with a certain concentration. Since hydrogen has antioxidant and anti-inflammatory effects, it can effectively inhibit the postharvest senescence of Chinese quince and extend its shelf life. The hydrogen concentration inside the equipment box can be detected according to the gas detection device installed on the sealing door.
[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, through the provided equipment box, external structures such as the cleaning module, air drying module, and hydrogen generation device can be embedded and installed in the slots opened on the outer side of the equipment box, so that after the Chinese quince is picked, it can be immediately subjected to preliminary cleaning, air drying, and preservation treatment, making the Chinese quince not easily affected by the external environment during the period from picking to cold chain transportation, reducing the probability of the Chinese quince being invaded by microorganisms and reducing its own metabolism, maintaining the quality indicators such as the hardness, color, and flavor of the Chinese quince, and improving its commercial value.
[0016] Through the provided spiral storage tank, the cleaned and air-dried Chinese quince can be stored in a spiral shape. Then, control the hydrogen generation device to electrolyze hydrogen and inject it into the equipment box from the bottom. After that, due to the characteristics of hydrogen itself, it will diffuse and distribute from bottom to top, soaking the spirally stored Chinese quince, playing a role in preserving the Chinese quince. At the same time, due to the spiral storage structure, when it is necessary to take out the stored Chinese quince later, there is no need for manual handling, and only need to open the baffle to quickly take it out, which is convenient for subsequent loading work.
[0017] In summary, the present invention conducts preliminary cleaning, air drying, and preservation of Chinese quince during the period from picking to loading and transportation, changing the problem that Chinese quince is easily affected by the external environment during the traditional period from picking to transportation, resulting in microbial invasion and accelerated self-metabolism, leading to quality decline and shortened shelf life, maintaining the quality indicators such as the hardness, color, and flavor of Chinese quince, and having the advantage of improving its commercial value.

Inside the front end of the device box 1, there is a hydrogen generation device 5. The hydrogen generation device 5 is an existing integrated small electrolytic water hydrogen production device, which is a mature and well-known technology in the art. Therefore, it will not be elaborated too much in this article. On the top of the device box 1, there is a photovoltaic panel 6, which can absorb heat and convert it into electricity when there is sunlight during the day, and then store the electricity through the battery pack inside the battery compartment 7 for powering the device during night picking. Inside the upper end of the device box 1, there is a battery compartment 7. In the middle of the right side of the outer end of the device box 1, there is a sealing door 8.

Zhang less likely to be affected by the external environment during the period from picking to cold chain transportation, reducing the probability of being invaded by microorganisms and reducing the metabolism of the Prunus salicina Lindl. var. cordata J. Y. Zhang & Y. B. Zhang itself, inhibiting the post-harvest senescence of the Prunus salicina Lindl. var. cordata J. Y. Zhang & Y. B. Zhang, and extending its preservation period.
[0029] Such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, in this embodiment, the equipment box 1 includes an integrated box body 101, an L-shaped corridor groove 102, a feeding port 103, a concave groove 104, and a wheel groove 105.

At the same time, since the three form an embedded installation structure with the integrated box body 101 and, under the condition of reasonable layout, reduce their own floor space, which is convenient for integration with the integrated box body 101 and reduces the overall size of the equipment box 1. Secondly, by providing the wheel grooves 105, appropriate tires can be installed inside, so that the equipment can be moved more quickly during subsequent handling.
[0031] As Figures 1 to 5 shown in the figure, in this embodiment, the cleaning module 2 includes a cleaning box 201, a control box 202, a circulation pump 203, a cleaning conveyor 204, a conveying motor 205, a cleaning tank 206, and a flushing rack 207.

A cleaning conveyor 204 is provided inside the cleaning box 201. The surface of the cleaning conveyor 204 is of a hollow structure to facilitate the flow of water. A conveying motor 205 is bolted and installed on the front side below the cleaning conveyor 204. Power is transmitted between the conveying motor 205 and the rotating shaft of the cleaning conveyor 204 through a belt.

A longitudinally running conveying structure is installed inside the air-drying conveying box 301. A feed hopper 302 is welded and installed at the rear end of the air-drying conveying box 301. The inside of the feed hopper 302 is of an inclined design. An inner inclined connecting box 303 is welded and installed at the front end of the air-drying conveying box 301. Intake fans 304 are longitudinally distributed on the upper end of the air-drying conveying box 301. Every three intake fans 304 form a group, and a total of six groups are distributed.

In the middle of the inner side of the chassis 901, a power supply box 902 is bolted and reinforced. Inside the power supply box 902, a storage battery is installed. In the middle of the upper end of the power supply box 902, an arc-shaped block 903 is bolted. At the upper end of the arc-shaped block 903, there is a docking support block 904. Among them, a clamping notch is opened at the lower end of the docking support block 904, and the diameter of the clamping notch is adapted to the overall size of the arc-shaped block 903. At the rear side of the arc-shaped block 903, there is an inclination motor 905. The transmission end of the inclination motor 905 penetrates through the inside of the docking support block 904 and extends to the inside of the arc-shaped block 903, and the contact end of the transmission end of the inclination motor 905 and the docking support block 904 is octagonally socket-fixed. Secondly, the inclination motor 905 and the power supply box 902 can be connected by a circuit. At the upper end of the docking support block 904, a material transfer turntable 906 is bolted and reinforced. On the left and right sides of the lower end of the material transfer turntable 906, there are anti-collision rods 907. The anti-collision rods 907 prevent the left and right sides of the lower end of the material transfer turntable 906 from colliding with the feeding belt 11.
[0033] By setting the inclination motor 905, since the contact end of its transmission end and the docking support block 904 is octagonally socket-fixed, as long as the inclination motor 905 works, it will drive the docking support block 904 to swing left and right, so that the material transfer turntable 906 bolted and reinforced with the docking support block 904 also tilts left and right, enabling the material transfer turntable 906 to change its conveying angle as needed.
[0034] As Figure 3 and Figure 8 As shown in the figure, in this embodiment, the spiral storage module 12 includes a spiral storage tank 121, a feeding port 122, a discharging port 123, a central support 124, and a pull rod 125. An interception net can be laid on the upper end of the spiral storage tank 121 as needed to prevent the occurrence of the situation where the Chinese flowering quince drops. And the spiral inclination angle of the spiral storage tank 121 is set between five and fifteen degrees, which can not only allow the Chinese flowering quince to roll inside but also prevent the Chinese flowering quince from dropping due to too large a slope. On the left side of the upper end of the spiral storage tank 121, a feeding port 122 is opened. On the right side of the lower end of the spiral storage tank 121, a discharging port 123 is opened. Both the feeding port 122 and the discharging port 123 have a certain slope. A baffle is installed on the inner side of the upper end of the discharging port 123. In the middle of the lower end of the spiral storage tank 121, there is a central support 124. The overall shape of the central support 124 is thicker at the top and thinner at the bottom, and it is reinforced with the outer end of the inner side of the spiral storage tank 121 through a pull rod 125. Above the outer end of the central support 124, there is a pull rod 125, and the pull rods 125 are symmetrically distributed in a ring shape.
[0035] By setting up the spiral storage trough 121, the washed and air-dried plums can be stored in a spiral shape, and then the hydrogen generator 5 is controlled to electrolyze hydrogen and inject it into the equipment box 1 from the bottom. After that, due to the characteristics of hydrogen itself, it will diffuse and distribute from bottom to top, soaking the spirally stored plums, thereby keeping the plums fresh.
[0036] A hydrogen-based plum preservation device, when in use, comprises the following steps; Step 1: Before starting work, the fresh-keeping equipment is towed to the plum orchard area by a vehicle and placed there. Then, the cleaning module 2 installed in the tail area of the equipment box 1 is injected with cleaning water, and each module of the fresh-keeping equipment is powered on through the line compartment 4; Step 2: The picked plums are put into the cleaning tank 206 opened at the rear side of the upper end of the cleaning box 201 through the feeding port 103, and then the circulation pump 203, the cleaning conveyor 204 and the conveying motor 205 are turned on in sequence through the control box 202, wherein the circulation pump 203 can extract the water flow injected into the cleaning box 201 and convey it to the washing rack 207, and then the injected plums are washed by the nozzles arranged and installed on the washing rack 207, and while washing, the conveying motor 205 will drive the cleaning conveyor 204 to rotate under the action of the belt, and convey the washed plums forward until the tail end of the cleaning conveyor 204; Step 3: After the cleaning conveyor 204 conveys the plums to the tail end, the plums will fall down into the feed hopper 302 due to the change in angle. Since the feed hopper 302 is designed to be inclined, the fallen plums will enter the air-drying conveying box 301 along the slope, and the plums will be conveyed forward by the internal conveying structure. During the conveying process, the air inlet fan 304 will draw external air to dry the surface of the plums passing through the interior. After the dried plums reach the tail end of the conveying structure, they will enter the inner inclined connecting box 303 for transfer, and then enter the feed pipe 10 connected thereto along the internal inclined angle, and then be conveyed to the inside of the equipment box 1 for storage; Step 4: The plums entering the equipment box 1 will first fall on the transfer plate 906, and then the tilting motor 905 will first drive the docking support block 904 to rotate clockwise, and one end of the transfer plate 906 will be tilted to the right first, so that the plums falling on the transfer plate 906 will be first transported to the right feeding belt 11. At the same time, the right feeding belt 11 will transport the plums falling on the upper end to the right side, and enter the feeding port 122 of the right spiral storage module 12, and then roll down along the spiral storage trough 121 until it falls on the baffle position near the discharge port 123 and stops. Then, when the right spiral storage module 12 is almost full from the lower spiral to the upper part, change the tilt angle of the transfer module 9; Step 5: When the tilting angle of the material transfer module 9 tilts to the left and contacts the left feeding belt 11, the Chinese flowering quince on the material transfer cross-disk 906 will be conveyed and stored into the internal spiral storage tank 121 of the left spiral storage module 12; Step 6: When both the left and right spiral storage modules 12 inside the equipment box 1 are full, close the sealing door 8, then turn on the hydrogen generation device 5 to produce hydrogen by electrolyzing water. After that, convey the hydrogen into the equipment box 1 so that the stored Chinese flowering quince is soaked in a hydrogen environment with a certain concentration. Since hydrogen has antioxidant and anti-inflammatory effects, it can effectively inhibit the postharvest senescence of Chinese flowering quince and extend its shelf life. The hydrogen concentration inside the equipment box 1 can be detected according to the gas detection device installed on the sealing door 8.
[0037] For the "influence of hydrogen on the fresh-keeping effect of Chinese flowering quince at different hydrogen concentrations and treatment times" mentioned in the above steps, the common indicators and formulas involved are as follows: 1. Weight loss rate: The weight loss rate reflects the loss of substances such as moisture during the fresh-keeping process of Chinese flowering quince. The calculation formula is: Weight loss rate (%) = (Initial mass - Treated mass) / Initial mass × 100%; 2. Rot rate: The rot rate is used to measure the degree of rot of Chinese flowering quince. The calculation formula is: Rot rate (%) = Number of rotten fruits / Total number of fruits × 100%; 3. Hardness retention rate: The hardness retention rate reflects the change in the hardness of Chinese flowering quince fruits and can, to a certain extent, reflect the freshness and quality of the fruits. The calculation formula is: Hardness retention rate (%) = Treated hardness / Initial hardness × 100%; 4. Change rate of soluble solid content: The soluble solid content is one of the important indicators for measuring the quality of Chinese flowering quince fruits. The calculation formula for its change rate is: Change rate of soluble solid content (%) = (Treated soluble solid content - Initial soluble solid content) / Initial soluble solid content × 100%; 5. Change rate of vitamin C content: The vitamin C content is also an important indicator for evaluating the fresh-keeping effect of Chinese flowering quince. The calculation formula is: Change rate of vitamin C content (%) = (Treated vitamin C content - Initial vitamin C content) / Initial vitamin C content × 100%; When analyzing the relationship between hydrogen concentration and treatment time on the preservation effect of Zui Li, some statistical analysis formulas may also be used. For example, the correlation coefficient calculation formula in correlation analysis: r is equal to the sum from i = 1 to n of the product of (xi minus the average value of x) and (yi minus the average value of y) as the numerator, and the denominator is the square root of [the sum from i = 1 to n of the square of (xi minus the average value of x) multiplied by the sum from i = 1 to n of the square of (yi minus the average value of y)].
[0038] Where xi and yi represent the values of hydrogen concentration (or treatment time) and a certain preservation effect index respectively, the average value of x and the average value of y are their respective average values, n is the sample size, and r is the correlation coefficient, which is used to judge the linear correlation degree between hydrogen concentration (or treatment time) and the preservation effect index.
[0039] The working principle of the technical solution provided by the present invention is as follows: Before starting work, first inject cleaning water flow into the cleaning module 2, and power on each module of the fresh-keeping equipment through the wiring compartment 4. Subsequently, the picked zuili plums are put into the cleaning tank 206 opened at the rear side of the upper end of the cleaning box 201 from the feeding port 103. Then, the circulating pump 203 pumps the water flow and transports it to the flushing rack 207. The nozzles installed downward in the middle of the flushing rack 207 flush the put-in zuili plums. While flushing, the conveying motor 205 drives the cleaning conveyor 204 to work, and transports the flushed zuili plums to the front end. Under the change of angle, the zuili plums will fall into the feeding hopper 302 and enter the air-drying conveying box 301. The internal conveying structure transports the zuili plums forward. During the conveying process, the intake fan 304 extracts external air to dry the surface of the passing zuili plums inside. The dried zuili plums enter the inner inclined connection box 303 for transfer and enter the feeding pipe 10 along the internal inclined angle, so as to be transported into the equipment box 1. The zuili plums entering the equipment box 1 will first fall on the transfer cross-disk 906. Then, the tilting motor 905 drives the docking support block 904 to rotate clockwise, tilting one end of the transfer cross-disk 906 to the right first, so that the zuili plums on the transfer cross-disk 906 fall into the right feeding belt 11 and are transported to a higher position on the right, and enter the feeding port 122 of the right spiral storage module 12. Then, they roll down along the spiral inclined angle until they stop at the position of the baffle near the discharge port 123. After that, when the right spiral storage module 12 is almost full inside, change the tilting angle of the transfer module 9 to tilt the transfer module 9 to the left, so that the zuili plums fall into the left feeding belt 11 and are transported and stored in the internal spiral storage tank 121 of the left spiral storage module 12. When both the left and right spiral storage modules 12 in the equipment box 1 are full, close the sealing door 8. Then, turn on the hydrogen generation device 5 to produce hydrogen by electrolyzing water, and transport the hydrogen into the equipment box 1, so that the stored zuili plums are soaked in a hydrogen environment with a certain concentration. Since hydrogen has antioxidant and anti-inflammatory effects, it can effectively inhibit the postharvest senescence of zuili plums and extend their fresh-keeping period.

The method for using the hydrogen-based Prunus salicina Lindl. preservation equipment according to claims 1-9, characterized in that, Including the following steps: Step 1: Before starting work, first tow the fresh-keeping equipment to the area of the Zui Li orchard by vehicle and place it. Then, inject cleaning water into the cleaning module (2) installed in the tail area of the equipment box (1), and power on each module of the fresh-keeping equipment through the line compartment (4). Step 2: Put the picked Zui Li into the cleaning tank (206) opened at the upper rear side of the cleaning box (201) from the feeding port (103). Then, turn on the circulation pump (203), the cleaning conveyor (204), and the conveying motor (205) in sequence through the control box (202). Among them, the circulation pump (203) can pump the water injected into the cleaning box (201) and transport it to the flushing rack (207). Then, the nozzles arranged on the flushing rack (207) flush the input Zui Li. While flushing, the conveying motor (205) will drive the cleaning conveyor (204) to rotate under the action of the belt, and transport the flushed Zui Li forward until the end of the cleaning conveyor (204). Step 3: When the cleaning conveyor (204) transports the Zui Li to the end, due to the change in angle, the Zui Li will fall into the feeding hopper (302). Since the inside of the feeding hopper (302) is inclined, the fallen Zui Li will enter the air-drying conveyor box (301) along the slope, and the internal conveying structure will transport the Zui Li forward. During the transportation process, the intake fan (304) will extract external air to dry the surface of the passing Zui Li inside. After the drying is completed, the Zui Li reaches the tail of the conveying structure and will enter the inner inclined connection box (303) for transfer, and then enter the feeding pipe (10) connected to it along the internal inclination angle, and thus be transported to the inside of the equipment box (1) for storage. Step 4: The Zui Li that enters the inside of the equipment box (1) will first fall on the transfer cross-disk (906). Then, the tilting motor (905) drives the docking support block (904) to rotate clockwise first, tilting one end of the transfer cross-disk (906) to the right side, so that the Zui Li falling on the transfer cross-disk (906) is first transported to the right feeding belt (11). At the same time, the right feeding belt (11) will transport the Zui Li falling on the upper end to a higher position on the right side and enter the feeding port (122) of the right spiral storage module (12). Then, it rolls down along the spiral storage groove (121) until it stops at the position of the baffle near the discharge port (123). Then, when the inside of the right spiral storage module (12) is almost full from the lower spiral to the upper spiral, change the tilting angle of the transfer module (9). Step 5: When the tilting angle of the transfer module (9) tilts to the left and contacts the left feeding belt (11), it will transport the Zui Li on the transfer cross-disk (906) to the internal spiral storage groove (121) of the left spiral storage module (12) for storage. Step 6: After both the left and right spiral storage modules (12) inside the equipment box (1) are filled, close the sealing door (8), then turn on the hydrogen generation device (5) to produce hydrogen by electrolyzing water. The hydrogen is then transported into the equipment box (1) so that the stored Chinese flowering quince is soaked in a hydrogen environment with a certain concentration. Since hydrogen has antioxidant and anti-inflammatory effects, it can effectively inhibit the postharvest senescence of Chinese flowering quince and extend its shelf life. The hydrogen concentration inside the equipment box (1) can be detected according to the gas detection device installed on the sealing door (8).
