Description

Technical Field

[0001] This utility model relates to the field of fruit sorting technology, specifically to a flexible buffer modified atmosphere device for cold chain sorting of apricots and plums. Background Technology

[0002] In the modern cold chain logistics system for agricultural products, apricots and plums, as fruits rich in nutrients and with high economic value, are crucial for ensuring product quality and extending shelf life through cold chain sorting. During the cold chain sorting process of apricots and plums, it is necessary not only to classify them efficiently and accurately, but also to avoid mechanical damage to the apricots and plums as much as possible during the sorting operation, and to effectively inhibit the oxidation reaction of apricots and plums during the sorting process to maintain their freshness and quality.

[0003] However, traditional apricot and plum sorting devices mostly focus on mechanical sorting functions, often using rigid structures for conveying and sorting apricots and plums. During the sorting process, the rigid contact between apricots and plums and the sorting equipment can easily cause damage such as bumps and scratches on the fruit surface, which seriously affects the appearance quality and commercial value of apricots and plums.

[0004] Furthermore, existing sorting devices typically lack effective controlled atmosphere functionality, failing to regulate the gaseous environment surrounding apricots and plums during the sorting process. This makes the apricots and plums prone to oxidation reactions with oxygen in the air during sorting, accelerating fruit aging and spoilage, and significantly shortening their shelf life. Therefore, there is an urgent need to design a flexible buffer controlled atmosphere device for cold chain sorting of apricots and plums to solve these problems. Utility Model Content

[0008] The top of the small gas tank is provided with a connecting pipe, the outer wall of the connecting pipe is provided with several branch pipes, the outer wall of the branch pipes is provided with several annular gas pipes, and the outer wall of the annular gas pipes is provided with several nozzles; the annular gas pipes are connected to the small gas tank through the branch pipes and the connecting pipe.

[0009] The top of the fixed plate is provided with a base, and the inner wall of the base is fixedly connected with a flow guide layer;

[0010] The top of the conveyor belt is provided with diversion rollers, which are used at least for sorting during the sorting process.

[0011] Preferably, the base is made of a highly elastic and strong flexible material, and the top surface of the base is provided with several curved and flexible grooves.

[0012] Preferably, the telescopic rod is a multi-stage nested telescopic rod, consisting of an outer tube and an inner tube, and the return spring is installed at the connection points of each stage of the telescopic rod and at the connection points between the telescopic rod and the fixed plate.

[0013] Preferably, the flow guiding layer is a microporous gas diffusion layer, and the micropore diameter of the microporous gas diffusion layer is between 0.1 and 1 mm to ensure that the gas can diffuse uniformly and stably.

[0014] Preferably, the small gas tank stores a CO2 / N2 mixture, which is released into the base through a nozzle and a guide layer on the annular gas pipe to suppress the oxidation reaction in the sorting process.

[0015] Preferably, the diverting roller is driven by a motor, which is electrically connected to an external control system and can control the rotation direction and speed of the diverting roller according to the sorting command.

[0016] In the above technical solution, the flexible buffer modified atmosphere device used in the apricot and plum cold chain separation provided by this utility model has the following beneficial effects:

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown in the embodiment of this utility model, the flexible buffer modified atmosphere device for sorting apricots and plums in a cold chain includes a conveyor belt 1 and a base plate 5. The top of the base plate 5 is respectively provided with a telescopic rod 11 and a small gas tank 10. The top of the telescopic rod 11 is provided with a fixing plate 13, and a return spring 12 is sleeved on the outer wall of the telescopic rod 11. The top of the small gas tank 10 is provided with a connecting pipe 9. The outer wall of the connecting pipe 9 is provided with several branch pipes 8. The outer wall of the branch pipes 8 is provided with several annular air pipes 6. The outer wall of the annular air pipes 6 is provided with several nozzles 7. The annular air pipes 6 are connected to the small gas tank 10 through the branch pipes 8 and the connecting pipes 9. The top of the fixing plate 13 is provided with a base 3, and the inner wall of the base 3 is fixedly connected with a flow guide layer 4. The top of the conveyor belt 1 is provided with a diversion roller 2, which is used at least for classification during sorting.

[0028] In this embodiment, a conveyor belt 1 and a base plate 5 are included. The length of the base plate 1 can be customized according to the actual use scenario. It can continuously and stably transport the apricots and plums to be sorted. The base plate 5 is perpendicular to the running direction of the conveyor belt 1 and is used to slide with the conveyor belt 1. The top of the base plate 5 is provided with telescopic rods 11 and small air tanks 10. There are four telescopic rods 11 in total, which are distributed in a rectangular array at the four corners of the top surface of the base plate 5. This layout can evenly support the fixed plate 13 above.

[0029] The top of the telescopic rod 11 is provided with a fixing plate 13, and the outer wall of the telescopic rod 11 is sleeved with a return spring 12. The telescopic rod 11 adopts a multi-level nested structure, which is composed of an outer tube and an inner tube that are nested together. The outer tube is fixedly installed on the base plate 5, and the inner tube can slide up and down and extend inside the outer tube.

[0030] Return springs 12 are installed at the connection points of each level of the telescopic rod and at the connection point between the telescopic rod 11 and the fixing plate 13. When the telescopic rod 11 is extended or retracted by external force, the return springs 12 can provide elastic force to return to the original position, ensuring that the telescopic rod 11 returns to its initial position after the work is completed. The fixing plate 13 is horizontally set at the top of the telescopic rod 11 and is fastened to the top of the inner tube of the telescopic rod 11 by bolts to ensure the stability of the connection.

[0031] The top of the small gas tank 10 is equipped with a connecting pipe 9. The small gas tank 10 is located in the middle of the top surface of the base plate 5. The connecting pipe 9 is vertically installed on its top. The connecting pipe 9 is sealed to the small gas tank 10 by welding to ensure that the gas does not leak.

[0032] The outer wall of the connecting pipe 9 is provided with several branch pipes 8, and the outer wall of the branch pipes 8 is provided with several annular air tubes 6. Several branch pipes 8 extend outward from the outer wall of the connecting pipe 9. The branch pipes 8 and the connecting pipe 9 are connected by T-shaped fittings, and the connection is sealed with sealing rings. Several annular air tubes 6 are evenly distributed on the outer wall of each branch pipe 8.

[0033] The outer wall of the annular gas pipe 6 is provided with several nozzles 7. The annular gas pipe 6 is connected to the small gas tank 10 through branch pipes 8 and connecting pipes 9. The annular gas pipe 6 is fixed to the branch pipes 8 by threaded connection. Several nozzles 7 are evenly distributed on the outer wall of the annular gas pipe 6. The nozzles 7 are integrally formed with the annular gas pipe 6 and can evenly spray the gas in the small gas tank 10. The annular gas pipe 6 is connected to the small gas tank 10 through branch pipes 8 and connecting pipes 9 to form a complete gas transmission and release system.

[0034] A base 3 is provided on the top of the fixing plate 13, and a base 3 is provided at the center of the top of the fixing plate 13. The base 3 is fixed to the fixing plate 13 by adhesive bonding to ensure a tight connection between the base 3 and the fixing plate 13.

[0035] A flow guide layer 4 is fixedly connected to the inner wall of the base 3. The flow guide layer 4 is fixed to the inner wall of the base 3 by adhesive, so as to ensure that the flow guide layer 4 can stably play the role of gas diffusion.

[0036] A sorting roller 2 is installed on the top of the conveyor belt 1. The sorting roller 2 is used for sorting during the sorting process. Multiple sorting rollers 2 are evenly distributed on the top surface of the conveyor belt 1, and the axis of the sorting roller 2 is perpendicular to the running direction of the conveyor belt 1. The sorting roller 2 is mounted on the support of the conveyor belt 1 by bearings and can rotate freely. Each sorting roller 2 is driven by an independent motor, which is fixedly installed below the support of the conveyor belt 1 and connected to the shaft end of the sorting roller 2 through a coupling. The motor is electrically connected to an external control system via a cable. The external control system can precisely control the speed and direction of each motor according to preset sorting instructions, thereby controlling the rotation direction and speed of the sorting roller 2 to achieve the sorting of apricots and plums.

[0037] Specifically, base 3 is made of a highly elastic and strong flexible material. The top surface of base 3 has several curved and flexible grooves. This material can elastically deform under external force, effectively buffering the impact of apricots during the sorting process. The shape of these grooves matches the shape of the apricots, providing stable support and preventing them from rolling and slipping.

[0038] Furthermore, the telescopic rod 11 is a multi-stage nested telescopic rod, composed of an outer tube and an inner tube. The return spring 12 is installed at the connection points of each stage of the telescopic rod and at the connection point between the telescopic rod 11 and the fixed plate 13. Moreover, the multi-stage nested structure of the telescopic rod 11 allows its extension stroke to be adjusted according to actual needs. During the apricot and plum sorting process, when different height positions need to be processed, the telescopic rod 11 can adjust the height of the base 3 by extending and retracting. The return spring 12 maintains a certain preload during the extension and retraction of the telescopic rod 11, ensuring the stability and reliability of the telescopic rod 11 during the extension and retraction process.

[0039] It should be noted that the flow guide layer 4 is a microporous gas diffusion layer. The micropore diameter of the microporous gas diffusion layer is between 0.1 and 1 mm, which ensures that the gas can diffuse evenly and stably. The flow guide layer 4 is a microporous gas diffusion layer. The micropore diameter of the microporous gas diffusion layer is between 0.1 and 1 mm. This microporous structure can effectively disperse the gas sprayed from the nozzle 7, so that the gas forms a uniform and stable airflow field in the base 3, ensuring that the gas can act evenly on the apricots in the base 3 and suppress the oxidation reaction in the sorting process.

[0040] It should be noted that the small gas tank 10 stores a CO2 / N2 mixture. This CO2 / N2 mixture is released into the apricots inside the base 3 through the nozzle 7 on the annular gas pipe 6 and the guide layer 4, suppressing the oxidation reaction during the sorting process. The CO2 / N2 mixture stored in the small gas tank 10 has excellent antioxidant properties. During operation, the small gas tank 10 is driven by internal pressure to deliver the CO2 / N2 mixture to the connecting pipe 9, then branched through the branch pipe 8 to each annular gas pipe 6, and finally sprayed out through the nozzle 7 on the annular gas pipe 6. Part of the gas acts directly on the surface of the apricots inside the base 3, while the other part diffuses into the internal space of the base 3 through the guide layer 4, comprehensively suppressing the oxidation reaction of the apricots during the sorting process.

[0041] It should be noted that the sorting roller 2 is driven by a motor, which is electrically connected to an external control system and can control the rotation direction and speed of the sorting roller 2 according to the sorting instructions.

[0042] Working steps: 1. Turn on the external control system and start the motor to put the diverter roller 2 into the ready state;

[0043] 2. Check the CO2 / N2 mixed gas storage in the small gas tank 10 to ensure that the controlled atmosphere system is normal and usable;

[0044] 3. Place the apricots and plums that need to be sorted into the designated position. The apricots and plums fall onto the base 3, and the highly elastic flexible base 3 and the groove provide initial cushioning.

[0045] IV. The telescopic rod 11 contracts under the weight of the plum tree, and the return spring 12 is compressed to absorb the impact force.

[0046] 5. The CO2 / N2 mixture in the small gas tank 10 enters the annular gas pipe 6 through the connecting pipe 9 and the branch pipe 8, and the mixture is sprayed out through the nozzle 7 on the annular gas pipe 6;

[0047] 6. The ejected gas is evenly dispersed through the guide layer 4 and surrounds the apricots and plums inside the base 3, thereby reducing the oxygen concentration around the apricots and plums, inhibiting oxidation, and extending the shelf life.

[0048] 7. When the apricots and plums arrive at the sorting roller 2, the external control system controls the motor to adjust the rotation direction and speed of the sorting roller 2 according to the preset instructions, so as to achieve the sorting of apricots and plums by specifications and quality.

[0049] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
