Abstract
Description
Technical Field
[0001] This utility model relates to the field of fruit and vegetable preservation, and in particular to an atomizing device for a sterilization solution used in fruit and vegetable preservation. Background Technology
[0002] Currently, with the development of the transportation industry, cultivated fruits and vegetables can be sold all over the world. During transportation, the fruits and vegetables release ethylene gas through respiration to help ripen. If fully ripe fruits and vegetables are not processed in time, they will quickly rot. Unsold fruits and vegetables will cause considerable losses to fruit farmers. Therefore, the preservation technology of fruits and vegetables is particularly important.
[0003] Current fruit and vegetable preservation technologies mainly include low-temperature refrigeration, chemical preservative treatment, and reduced-pressure storage. However, there are many inconveniences in using sterilization solutions suitable for fruit and vegetable preservation by spraying or soaking them under normal pressure. After sterilization under normal pressure, residual droplets are prone to microbial growth and accelerate the loss of moisture from the surface of fruits and vegetables. The water droplets remaining on the surface of fruits and vegetables are not conducive to quality preservation and affect the subsequent preservation effect. Utility Model Content
[0004] This invention provides an atomizing device for a sterilization solution used for fruit and vegetable preservation, in order to solve the problem that sterilization under normal pressure will cause water droplets to remain on the surface of fruits and vegetables, which is not conducive to subsequent preservation.
[0005] To achieve the above objectives, this utility model provides an atomizing device for a sterilization solution used for fruit and vegetable preservation, including an atomizing box with atomizing plates, the atomizing box containing a sterilization solution, and the atomizing box having a mist delivery port and a return air port. A pressure control module, which includes a pressure transmitter, wherein the pressure transmitter is disposed inside the atomizing box; An air supply device is located inside the atomizing box, and the air supply direction of the air supply device corresponds to the mist delivery port.
[0006] Preferably, the above technical solution also includes a vacuum tank, which is connected to the mist delivery port and the return air port of the atomizing box through a mist delivery pipe and a return air pipe, respectively.
[0007] Preferably, in the above technical solution, the air pressure control module further includes a vacuum pump, which is connected to the vacuum tank.
[0008] Preferably, the above technical solution further includes a replenishment tank and a level gauge. The level gauge is located inside the atomizing box. The replenishment tank is connected to the atomizing box via a replenishment pipe. The replenishment pipe is equipped with a solenoid valve. The air pressure value of the replenishment tank is greater than the air pressure value of the vacuum tank.
[0009] Preferably, in the above technical solution, the atomizing box is equipped with a pressure-resistant door that can be opened and closed.
[0010] Preferably, in the above technical solution, the air pressure control module further includes a controller, a power supply, a first relay, and a second relay. The first electrode of the power supply is connected to one end of the first relay and one end of the second relay, respectively. The second electrode is connected to one end of the atomizing plate, the air supply device, the solenoid valve, and the level gauge, respectively. The other end of the first relay is connected to the other end of the driver of the atomizing plate, the air supply device, and the pressure transmitter, respectively. The other end of the second relay is connected to the solenoid valve and the level gauge, respectively.

[0011] Preferably, in the above technical solution, the atomizing box is provided with series branch pipes.
[0012] Preferably, in the above technical solution, the atomizing sheet is a corrosion-resistant atomizing sheet.
[0013] Preferably, in the above technical solution, the air supply device is a fan.
[0014] Compared with existing technologies, this utility model has the following beneficial effects: 1. The atomizing device for the sterilization solution used in the preservation of fruits and vegetables of this utility model operates when the pressure transmitter detects that the atomizing chamber has reached the set negative pressure value. After the solution is atomized, the air supply device blows the mist towards the mist delivery port. The mist enters the vacuum tank from the mist delivery pipe. The atomized sterilization solution gives the effective sterilization ingredients better penetration, which not only improves the efficiency and effect of sterilization, but also solves the problem that water droplets remaining on the surface of fruits and vegetables after sterilization under normal pressure are not conducive to quality preservation and affect subsequent preservation.
[0015] 2. This utility model controls the air pressure value of the atomizing box through an air pressure control module. At this time, the air pressure value in the replenishment tank is greater than the air pressure value in the atomizing box. When the level gauge detects that the solution in the atomizing box is insufficient, the solenoid valve opens. Due to the pressure difference between the replenishment tank and the atomizing box, the solution in the replenishment tank will automatically flow into the atomizing box through the replenishment pipe to replenish the solution in the atomizing box.
[0016] 3. The return air duct installed between the vacuum chamber and the atomizing chamber in this utility model can maintain the air pressure balance between the atomizing chamber and the vacuum chamber.

One replenishment tank can supply liquid to multiple atomizing boxes, and each atomizing box is connected to a vacuum tank, which improves the efficiency of fruit and vegetable preservation.
[0018] 5. The components inside the atomizing box of this utility model can be inspected and repaired by opening the pressure-resistant door. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the circumstances. The embodiments of this utility model will be described below based on its overall structure.
[0027] like Figures 1-3 As shown, the essential oil atomizing device for preserving fruits and vegetables in this embodiment includes: an atomizing box 1, an atomizing plate 10, a level gauge 11, a fan 12, a mist conveying pipe 13, a return air pipe 14, a series branch pipe 15, a pressure-resistant door 16, a vacuum tank 2, a replenishment tank 3, a replenishment pipe 30, and a solenoid valve 31.
[0028] refer to Figure 3 The controller U1 is electrically connected to the pressure transmitter PT, the atomizing plate 10, and the air supply device, respectively, and controls the orderly operation of each component. Specifically, the first electrode of the power supply DC is connected to one end of the normally open switch k1-1 of the first relay k1, and the second electrode is connected to one end of the atomizing plate 10 and the air supply device, respectively. The other end of the normally open switch k1-1 of the first relay k1 is connected to the other end of the driver of the atomizing plate 10, the air supply device, and the pressure transmitter PT, respectively. The controller U1 is connected to the first relay k1 and the pressure transmitter PT, respectively.
[0029] In addition, the atomizing plate 10 is preferably a corrosion-resistant atomizing plate, and the air supply device is preferably a fan 12.
[0030] refer to Figures 1-2 The atomizing box 1 contains a sterilization solution. The atomizing box 1 is equipped with an atomizing plate 10 and a fan 12. The atomizing plate 10 is used to atomize the sterilization solution. The atomizing box 1 has a mist delivery port, which corresponds to the air delivery direction of the fan 12. The atomized solution will be blown by the fan 12 to the mist delivery port.
[0031] A vacuum pump is connected to a vacuum tank 2, which contains stacked fruits and vegetables. The operation of the vacuum pump keeps the vacuum tank 2 under low pressure, which not only inhibits bacterial growth on the surface of the fruits and vegetables but also slows down their ripening process, thus facilitating their preservation. A pressure transmitter PT is also installed in the atomizing box 1. The vacuum tank 2 is connected to the atomizing box 1's atomizing port via a mist delivery pipe 13. At this time, the atomizing box 1 is also under low pressure. When the pressure transmitter PT detects the preset negative pressure value, the atomizing plate 10 operates, and the atomized solution enters the vacuum tank 2 through the mist delivery pipe 13, covering a larger area of the fruits and vegetables, resulting in better sterilization and reducing moisture loss.
[0032] In this embodiment, when the pressure transmitter PT detects that the set negative pressure value has been reached in the atomizing chamber 1, the atomizing plate 10 atomizes the sterilization solution, and the fan 12 blows the mist towards the mist delivery port. The mist enters the vacuum tank 2 from the mist delivery pipe 13. At this time, the effective components of the sterilization solution have better penetration, which not only improves the efficiency and effect of sterilization, but also solves the problem that water droplets remaining on the surface of fruits and vegetables after sterilization under normal pressure are not conducive to quality maintenance and affect subsequent preservation.
[0033] In addition, if too much atomized solution adheres to fruits and vegetables, it will not only affect the taste of the fruits and vegetables, but may also increase the amount of pesticide residues on the surface of the fruits and vegetables. Long-term consumption will affect human health. Therefore, it is necessary to set the working time of the atomizing plate 10 to avoid the above problems and also prevent the waste of atomized solution.
[0034] The atomizing box 1 has a return air vent, and the vacuum can 2 is connected to the return air vent of the atomizing box 1 through the return air duct 14. During the delivery of mist, the return air duct 14 can maintain the air pressure balance between the vacuum can 2 and the atomizing box 1.
[0035] The atomizing box 1 is also equipped with a pressure-resistant door 16 that can be opened and closed. Opening the pressure-resistant door 16 allows for the inspection and maintenance of the components inside the atomizing box 1, while closing the pressure-resistant door 16 allows for atomization operations. In addition, the atomizing box 1 is also equipped with a drain pipe (not shown in the figure). When the atomizing box 1 is not used for a long time, the sterilization solution needs to be drained out of the atomizing box 1 through the drain pipe to prevent the atomizing plate 10 from being soaked for a long time, which would cause corrosion and greatly shorten the service life of the atomizing plate 10.
[0036] In this embodiment, a replenishment tank 3 is added to supply sterilization solution to the atomizing box 1. Specifically, a level gauge 11 is installed inside the atomizing box 1, and the atomizing box 1 is connected to the replenishment tank 3 via a replenishment pipe 30. The replenishment pipe 30 is equipped with a solenoid valve 31, and the air pressure value of the replenishment tank 3 is greater than the air pressure value of the vacuum tank 2.
[0037] For more specific details, please refer to [link / reference]. Figure 3The controller U1 is electrically connected to the solenoid valve 31 and the level gauge 11 respectively. The first electrode of the power supply DC is connected to one end of the normally open switch k2-1 of the second relay k2, and the second electrode is connected to one end of the solenoid valve 31 and the level gauge 11 respectively. The other end of the normally open switch k2-1 of the second relay k2 is connected to the solenoid valve 31 and the level gauge 11 respectively. The controller U1 is connected to the control terminal of the second relay k2.
[0038] When the level gauge 11 detects that the solution in the atomizing box 1 is insufficient, the controller U1 controls the solenoid valve 31 to open. Because the pressure difference between the replenishment tank 3 and the atomizing box 1 is formed, the solution in the replenishment tank 3 will automatically flow into the atomizing box 1 through the replenishment pipe 30 to replenish the solution in the atomizing box 1.
[0039] In addition, the atomizing box 1 is also equipped with a series branch pipe 15, which is used to transport the sterilization solution. The first atomizing box 1 can be connected to the second atomizing box 1 through the series branch pipe 15, and the second atomizing box 1 can also be connected to the third atomizing box 1 through the series branch pipe 15, and so on. Furthermore, each atomizing box 1 is connected to a vacuum tank 2, so the fruits and vegetables in each vacuum tank 2 can be preserved simultaneously, improving the efficiency of fruit and vegetable preservation. At this time, the solution level in each atomizing box 1 is consistent, and one replenishment tank 3 can supply solution to multiple atomizing boxes 1 simultaneously, reducing replenishment costs and improving replenishment efficiency.
