[0002] Ethylene is an endogenous plant hormone. Its physiological function is mainly to promote the ripening of fruits and seeds, and the shedding of leaves, flowers and fruits. It also has the functions of inducing flower bud differentiation, breaking dormancy, promoting germination, continuous flowering, dwarfing plants and promoting adventitious root formation.

[0003] Fruits and vegetables produce a large amount of ethylene during storage, which can cause them to mature and rot quickly. Ethylene needs to be removed in fruit and vegetable fresh-keeping warehouses to ensure their shelf life. Existing ethylene removal methods mostly remove ethylene from the storage environment by installing ozone generators. However, ozone has strong oxidizing properties and is harmful to metals and fruits. Furthermore, these methods are expensive, complex in structure, and inconvenient to maintain.

[0004] Therefore, an ethylene removal machine for fruits and vegetables is proposed. Utility Model Content

[0023] The present invention provides an ethylene removal machine for fruits and vegetables, such as Figures 1-5 As shown, it includes a fuselage 1, on the outer wall of one side of the fuselage 1 are welded a fresh-keeping storage air outlet pipe 2 and a fresh-keeping storage return pipe 4, the fresh-keeping storage air outlet pipe 2 is located above the fresh-keeping storage return pipe 4, and the end of the fresh-keeping storage air outlet pipe 2 away from the fuselage 1 is fixedly connected with a first exhaust fan 3 by bolts, on the outer wall of the other side of the fuselage 1 near the fresh-keeping storage air outlet pipe 2 and the fresh-keeping storage return pipe 4, a connecting pipe 5 is welded, a stepping motor 6 is fixedly connected with a stepping motor 6 at a central position of the outer wall of one side of the fuselage 1 by bolts, the stepping motor 6 is fixedly connected with a rotating frame 7 through the output end of one side thereof, an adsorbent filling cavity 8 is provided on the outer wall of one side of the rotating frame 7, the interior of the adsorbent filling cavity 8 is filled with adsorbent, and the adsorbent is alumina adsorbent, and an anti-fouling agent is provided on the inner wall of one side of the adsorbent filling cavity 8. Protective net 9, a hot air inlet duct 10 is welded to the outer wall of one side of the fuselage 1 near the air outlet duct 2 of the fresh-keeping storage, and the end of the hot air inlet duct 10 away from the fuselage 1 is fixedly connected to the heating sleeve 11 by bolts, and the end of the heating sleeve 11 away from the hot air inlet duct 10 is fixedly connected to the second exhaust fan 12 by bolts, and a hot air outlet duct 13 is welded to the outer wall of the other side of the fuselage 1 near the hot air inlet duct 10, and a third exhaust fan 14 is fixedly connected to the lower position of the hot air inlet duct 10 on the outer wall of one side of the fuselage 1 by bolts, and a natural wind outlet duct 15 is welded to the outer wall of the other side of the fuselage 1 near the third exhaust fan 14, and a partition 16 is integrally formed on the inner wall of one side of the fuselage 1, and the outer side walls of the rotating frame 7 and the partition 16 are precisely matched.

[0024] It should be noted that, since most of the existing ethylene removal methods are carried out by installing ozone machines to remove ethylene from the storage environment, but ozone has strong oxidizing properties and is harmful to metals and fruits, and is also expensive, has a complex structure and is inconvenient to maintain, this embodiment uses the step-by-step axial rotation of the rotating frame 7 to allow the adsorbent in the adsorbent filling chamber 8 to sequentially adsorb ethylene from the gas in the fresh-keeping warehouse, reduce the adsorbent by heat, cool the adsorbent by natural wind, and cool the adsorbent in the fresh-keeping warehouse by cold air. The circulating structure can continuously remove ethylene from the gas in the fresh-keeping warehouse, which has little impact on fruits and vegetables, is simple in structure, inexpensive, and easy to repair and maintain.

[0025] Specifically, in this embodiment, this scheme mainly includes a rotating frame 7. When in use, the fuselage 1 is installed and fixed on the outer wall of the fruit and vegetable fresh-keeping warehouse, and the first exhaust fan 3 is installed and fixed on the inner wall of the fresh-keeping warehouse. The fresh-keeping warehouse outlet pipe 2 passes through the fresh-keeping warehouse, and the fresh-keeping warehouse return pipe 4 passes through the inner side of the fresh-keeping warehouse. Corresponding sealing measures are taken. When the ethylene removal operation is performed, the first exhaust fan 3 extracts the air containing ethylene in the fruit and vegetable fresh-keeping warehouse, and the air containing ethylene enters the fuselage 1 through the fresh-keeping warehouse outlet pipe 2. The air passes through the protective net 9 and enters the adsorbent filling chamber 8. The adsorbent in the adsorbent filling chamber 8 adsorbs the ethylene in the air. The air with ethylene removed is guided to the fuselage 1 through the connecting pipe 5, and flows back to the fruit and vegetable fresh-keeping warehouse under the guidance of the fresh-keeping warehouse return pipe 4. The working interval of the stepping motor 6 is set, and the stepping motor 6 drives the rotating frame 7 to rotate 90 degrees through the output end on one side thereof, and the ethylene adsorbed The adsorbent rotates axially to between the hot air inlet pipe 10 and the hot air outlet pipe 13, and the second exhaust fan 12 draws external air into the heating sleeve 11. The electric heating wire in the heating sleeve 11 heats the air, and the hot air enters the fuselage 1 under the guidance of the hot air inlet pipe 10, and the hot air is blown to the adsorbent filled in the adsorbent filling chamber 8. After the adsorbent is heated, the adsorbed ethylene is released, and the ethylene-containing air is discharged through the hot air outlet pipe 13 along with the hot air. At this time, the stepper motor 6 drives the rotating frame 7 to rotate 90 degrees again through the output end on one side, and the active adsorbent rotates axially to the third exhaust fan 14 and the natural wind outlet pipe 15. The third exhaust fan 14 draws external air into the fuselage 1, and the air contacts the adsorbent to cool it and is discharged from the natural wind outlet pipe 15. When the adsorbent rotates to between the fresh-keeping storage return pipe 4 and the connecting pipe 5, the fresh-keeping storage cold air that has removed the ethylene is blown to the adsorbent, thereby cooling the adsorbent and ensuring that the adsorbent has adsorption activity.

[0026] In a further preferred embodiment of the present invention, Figures 1-2 As shown, the fresh-keeping storage outlet pipe 2, the fresh-keeping storage return pipe 4, the connecting pipe 5, the hot air inlet pipe 10, the hot air outlet pipe 13, the third exhaust fan 14 and the natural air outlet pipe 15 are all connected to the fuselage 1, and the cross section of the connecting pipe 5 is a U-shaped structure.

[0027] In this embodiment, through the interconnected structure, air can enter and exit the fuselage 1 through the fresh-keeping storage outlet pipe 2, the fresh-keeping storage return pipe 4, the connecting pipe 5, the hot air inlet pipe 10, the hot air outlet pipe 13, the third exhaust fan 14 and the natural wind outlet pipe 15, ensuring the smooth flow of air. By utilizing the U-shaped connecting pipe 5, the air extracted from the fruit and vegetable fresh-keeping storage can be returned to the fresh-keeping storage after undergoing de-olefination.

[0028] In a further preferred embodiment of the present invention, Figures 1-2 As shown, an electric heating wire is provided on the inner wall of the heating sleeve 11, the hot air inlet pipe 10 and the second exhaust fan 12 are both connected to the heating sleeve 11, and the fresh-keeping storage air outlet pipe 2 is connected to the first exhaust fan 3.

[0029] In this embodiment, the heating jacket 11 can be used to heat the air through the electric heating wire, and then the hot air is used to reduce the adsorbent to ensure that the adsorbent is active.

[0030] In a further preferred embodiment of the present invention, Figure 3 and Figure 5 As shown, there are four adsorbent filling chambers 8 , and the four adsorbent filling chambers 8 are symmetrically opened inside the rotating rack 7 .

[0031] In this embodiment, by the step-by-step axial rotation of the four adsorbent filling chambers 8, the adsorbents in the four adsorbent filling chambers 8 can be subjected to ethylene adsorption, thermal reduction, natural wind cooling and cold air cooling respectively.
