Description

Apparatus for Washing and Treatment Agricultural Products using Ozon Water}

The present invention relates to an agricultural product washing and treatment apparatus using ozone water.

Sterilization is an essential process for cleaning agricultural products. Here, sterilization refers to a process of improving the preservation of food and removing bacteria harmful to the human body through a physical or chemical method.

There are largely a heat sterilization method and a non-heat sterilization method for sterilizing agricultural products. Here, since the heat sterilization method is a sterilization method in which heat is applied, a change in physical properties (taste, aroma, nutritional components, etc.) of the food can be caused, and thus the non-heat sterilization method is drawing attention.

Non-heat sterilization methods include, for example, ultra-high pressure sterilization, high voltage pulse sterilization, and ozone sterilization. Of these, ultra-high pressure sterilization is a device industry that requires investment of billions of billions, and is very expensive, and high voltage pulse sterilization is currently under research and development, but there is almost no commercial use. On the other hand, ozone sterilization is in the spotlight as an advantage of requiring less cost compared to other non-heating sterilization.

However, ozone sterilization according to the prior art usually sterilizes agricultural products by producing ozonated water, but there is a problem that a complicated configuration such as a pressurized tank is required to produce high-concentration ozone water.

Hereinafter, in describing the present invention, detailed descriptions of related known technologies that may unnecessarily obscure the subject matter of the present invention will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a side view of an apparatus for washing and treating agricultural products using ozonated water according to an embodiment of the present invention, and FIG. 2 is a perspective view of an apparatus for washing and treating agricultural products using ozonated water according to an embodiment of the present invention.

1 to 2, the agricultural product washing and treatment apparatus using ozone water according to the present embodiment includes a first supply unit 100 for supplying raw water, a second supply unit 200 for supplying air, and a second supply unit 200 for supplying air. 2 By receiving air from the supply means 200, the ozone generating means 300 for generating ozone gas, raw water is supplied from the first supply means 100, and ozone gas is supplied from the ozone generating means 300, Mixing means 400 for generating ozone water by dissolving ozone gas in raw water, spraying means 500 for receiving ozone water and ozone gas from the mixing means 400 and spraying them on agricultural products, and ozone sprayed from the spraying means 500 It includes an exhaust means 600 for exhausting the gas.

The first supply means 100 serves to supply raw water to the mixing means 400. Here, the first supply means 100 may be tap water supplied from a tap water, for example. Specifically, the first supply means 100 may include a filter 110 and a pressure pump 120. At this time, the filter 110 is connected to a faucet to receive tap water, which is raw water, and purify it. In addition, the pressure pump 120 receives the purified raw water from the filter 110, pressurizes it, and supplies it to the mixing means 400.

Meanwhile, a flow sensor 700 for transmitting an operation signal by sensing that raw water is transmitted from the filter 110 to the pressurizing pump 120 may be additionally provided. This flow sensor 700 plays a role of controlling the operation of the ozone generating means 300, the first supply means 100, the pressure pump 120, and the second supply means 200 (air pump) together with the control unit. However, specific details related to this will be described later.

The second supply means 200 serves to supply air to the ozone generating means 300. Here, the second supply means 200 may be, for example, an air pump that absorbs air in the atmosphere and supplies it to the ozone generating means 300. Conventionally, an oxygen supply is used, but since a nitrogen removal device or the like is required to supply oxygen, the configuration is relatively complicated and manufacturing cost is high. On the other hand, in this embodiment, since the air pump is used as the second supply means 200, the configuration is relatively simple and the manufacturing cost is low.

The ozone generating means 300 receives air from the second supply means 200 and serves to generate ozone gas. Here, the ozone generating means 300 may be, for example, a micro plasma device. Such a micro plasma device does not require a high voltage to generate plasma of the injection gas, and can generate excellent low-temperature plasma at less than about 2000V. Therefore, a large cooling device or the like for heat dissipation is unnecessary. On the other hand, the conventional corona discharge requires a high voltage of 7000V to 10000V, and high heat is accompanied when plasma is generated, so that a large cooling device for heat generation is required.

Specifically, in the micro plasma device, a microchannel having a size of several micrometers to several hundreds of micrometers is formed on an insulating support, and an electrode is provided inside the microchannel. Accordingly, the air supplied from the second supply means 200 may be introduced into the microchannel inlet, converted into ozone gas by applying a high voltage through the electrode, and then discharged through the microchannel outlet.

The mixing means 400 serves to generate ozone water by dissolving ozone gas in raw water. Here, the mixing means 400 receives raw water from the pressure pump 120 of the first supply means 100 and receives ozone gas from the ozone generating means 300. At this time, the mixing means 400 may include a venturi pipe 410 connected to the first supply means 100 to deliver raw water, and connected to the ozone generating means 300 to transfer ozone gas. . The venturi pipe 410 has a small diameter portion 415 in which the flow path is narrowed in the middle of the pipe, and the cross-sectional area in the small diameter portion 415 decreases, thereby increasing the flow velocity and reducing the pressure. Accordingly, when the raw water passes through the venturi pipe 410, the pressure in the small diameter portion 415 is reduced, so that the ozone gas supplied to the small diameter portion 415 is sucked, and as a result, the ozone gas may be dissolved in the raw water. Additionally, the mixing means 400 may further include first and second pressure reducing valves 420 and 430 in order to adjust the pressure of the raw water. Here, the first pressure reducing valve 420 is disposed between the pressure pump 120 of the first supply means 100 and the venturi pipe 410, and may adjust the pressure of the raw water flowing into the venturi pipe 410. In addition, the second pressure reducing valve 430 is disposed between the injection means 500 and the venturi pipe 410 to adjust the pressure of the raw water discharged from the venturi pipe 410. For example, the first pressure reducing valve 420 adjusts the pressure of raw water between the inlet of the venturi pipe 410 and the small diameter part 415, and the second pressure reducing valve 430 is connected to the outlet of the venturi pipe 410 It is possible to adjust the pressure of the raw water between the small diameter portion 415. In this way, by adjusting the pressure of the raw water passing through the venturi pipe 410 using the first and second pressure reducing valves 420 and 430, the amount of ozone gas sucked into the venturi pipe 410 can be controlled. .

In addition, the concentration of ozone water generated by dissolving ozone gas in raw water in the venturi pipe 410 may have a relatively low concentration (for example, 0.5 ppm to 1 ppm). All ozone gas supplied to the venturi pipe 410 is not dissolved in the raw water, and ozone gas not dissolved in the raw water is delivered to the injection means 500 together with the ozone water.

Additionally, a check valve 350 may be provided between the ozone generating means 300 and the venturi pipe 410 of the mixing means 400. Here, the check valve 350 is provided in the connection line 340 connecting the ozone generating means 300 and the venturi pipe 410 of the mixing means 400, and the mixing means 400 from the ozone generating means 300 It is possible to prevent the ozone gas from passing in the direction of the venturi pipe 410 of the mixing unit 400 and the passage of raw water from the venturi pipe 410 of the mixing unit 400 toward the ozone generating unit 300. In this way, the check valve 350 passes only the ozone gas in the direction of the venturi pipe 410 of the mixing means 400, and prevents the raw water from passing in the direction of the ozone generating means 300, so that the ozone generating means 300 Raw water is transferred to the ozone generating means 300 to prevent a short from occurring. More specifically, the check valve 350 may be a solenoid check valve 355 that opens and closes according to an electrical signal. Accordingly, when the solenoid check valve 355 is opened according to an electrical signal, ozone gas can pass through, and when the solenoid check valve 355 is closed by an electrical signal, it is possible to prevent ozone gas from passing through. Here, the electric signal for controlling the solenoid check valve 355 may be transmitted from the control unit, and detailed information related thereto will be described later.

The spraying means 500 receives ozone water and ozone gas (ozone gas not dissolved in raw water) from the mixing means 400 and injects ozone water onto agricultural products. Here, the injection means 500 may include a body portion 510 and an injection hole 520 (see FIG. 2 ). At this time, the body part 510 is formed in a tubular shape to receive ozone water and ozone gas from the mixing means 400. In addition, a plurality of injection ports 520 are disposed along the longitudinal direction of the body part 510 to inject the ozone water and ozone gas delivered from the body part 510. That is, the injection means 500 may be a kind of drop-type discharge pipe. Agricultural products such as citrus fruits may be continuously moved by the conveyor 800 under the spraying means 500. Therefore, agricultural products such as citrus fruits can be washed by the ozone water sprayed from the spraying port 520 of the spraying means 500 while being moved by the conveyor 800.

The exhaust means 600 serves to exhaust the ozone gas injected from the injection means 500. Specifically, the ozone gas that is not dissolved in the raw water in the mixing means 400 is injected from the injection means 500, and the ozone gas may be harmful to the human body, so the ozone gas injected from the injection means 500 is an exhaust means ( 600). As a result, this embodiment prepares low-concentration ozone water and exhausts ozone gas not dissolved in the raw water to the exhaust means 600, so that a complicated configuration such as a pressurized tank is unnecessary, and damage to the human body due to the remaining ozone gas is prevented. Can be prevented. Meanwhile, the exhaust means 600 may be disposed above the body portion 510 to effectively exhaust the ozone gas injected from the injection port 520. In addition, the exhaust means 600 is not particularly limited, for example, may be formed in the form of a hood, and a blower (640, blower) is connected to the exhaust means 600 to suck the ozone gas to the outside. Can be discharged.

On the other hand, Figures 3 to 4 are perspective views showing a modified example of the spraying means and the exhaust means of the agricultural product washing and treatment apparatus using ozone water according to the present embodiment, referring to this, the injection means 500 and the exhaust means 600 Let's describe a variation of.

First, as shown in FIG. 3, the exhaust means 600 may include a cover portion 610 and an exhaust portion 620. Here, the cover part 610 may be formed in a tubular shape to surround the body part 510 of the spraying means 500 and collect ozone gas. That is, the cover part 610 is formed to surround the body part 510 of the spraying means 500 as a whole, so that the ozone gas injected from the injection hole 520 of the spraying means 500 can be effectively collected. In addition, in the cover part 610, an area (lower area) facing the injection hole 520 of the injection means 500 may be opened in the form of a slit 615. Accordingly, the ozone water injected from the injection port 520 of the injection means 500 can be delivered to the agricultural product without being disturbed by the cover part 610. Meanwhile, the exhaust part 620 extends in a tubular shape from the cover part 610, and a blower may be connected. Accordingly, the exhaust port 630 may suck in the ozone gas collected by the cover part 610 and discharge it to the outside.

In addition, as shown in FIG. 4, the injection means 500 may include an injection unit 530 formed in a tubular shape to discharge ozone water downward. Specifically, a plurality of through holes 535 are formed under the injection unit 530, so that ozone water can be injected in the direction of agricultural products through the plurality of through holes 535. In addition, the exhaust means 600 may be formed in a tubular shape above the injection unit 530 and may include an exhaust port 630 for exhausting ozone gas. At this time, a blower is connected to the exhaust port 630 so that ozone gas is sucked and discharged to the outside. That is, the liquid ozonated water is injected through the injection port 520 disposed at a relatively lower side, and the ozone gas, which is a gas, may be exhausted through the exhaust port 630 disposed at the relatively upper side.

Additionally, the exhaust means 600 may further include an ozone removal means 650 for adsorbing ozone gas or removing it through a chemical reaction. For example, as the ozone removing means 650, activated carbon or an accumulator may be used. This ozone removing means 650 is provided in the exhaust means 600 to completely remove ozone gas exhausted to the outside (in this case, an exhaust line connected to the outside may be omitted), or can reduce the amount of ozone gas. have.

Although the ozone removing means 650 is shown in the modified example of FIG. 4, it is not limited thereto, and of course, the ozone removing means 650 may be applied to the embodiment of FIG. 2 or the modified example of FIG. 3.

Meanwhile, as shown in FIG. 1, the present embodiment may further include a flow sensor 700 and a control unit to control the overall operation. Here, the flow sensor 700 is provided between the filter 110 of the first supply means 100 and the pressure pump 120, from the filter 110 of the first supply means 100 to the pressure pump 120 When raw water is delivered, it can be sensed and an operation signal can be transmitted. That is, when tap water, which is raw water, is transmitted from the tap water to the first supply means 100, the flow sensor 700 detects it and transmits an operation signal. The operation signal transmitted from the flow sensor 700 is received by the control unit. In this way, when the control unit receives an operation signal from the flow sensor 700, the control unit includes the first supply unit 100, the pressure pump 120, the second supply unit 200, and the ozone generating unit 300. , Micro plasma device) to operate by supplying power. In addition, when the control unit receives an operation signal from the flow sensor 700, the control unit transmits an electrical signal to the solenoid check valve 355 to open the solenoid check valve 355. Eventually, in this embodiment, when raw water is supplied, the flow sensor 700 detects it, and the first supply means 100, the pressure pump 120, the second supply means 200, the air pump, and the ozone generating means ( 300, micro plasma device) is automatically operated, and the solenoid check valve 355 is automatically opened. That is, in the present embodiment, separate control is not required, and when raw water is supplied, electrical components are automatically operated so that ozone water can be generated and sprayed.

More specifically, as shown in FIG. 5, the flow sensor 700 may include a flow path 710 and an operation unit 720. Here, the flow path 710 is a path through which the raw water passes, and the operation unit 720 is disposed so as to cross the flow path 710, and when the raw water passes through the flow path 710, it may be rotated by the raw water. In this way, when the operation unit 720 is rotated by raw water, the flow sensor 700 transmits an operation signal, so that the control unit 100, the pressure pump 120, the second supply unit 200, Air pump), and the ozone generating means 300 (micro plasma device) may be operated, and the solenoid check valve 355 may be opened.

6 to 8 are side views showing the operation of the apparatus for washing and treating agricultural products using ozonated water according to an embodiment of the present invention, and referring to this, the operation of the apparatus for washing and treating agricultural products using ozonated water according to the present embodiment is shown. Let's take a look.

First, as shown in FIG. 6, raw water, such as tap water, is supplied to the filter 110 of the first supply means 100 to be purified. When the purified raw water passes through the flow sensor 700, the flow sensor 700 transmits an operation signal, and the control unit receives the operation signal to receive the first supply means 100, the pressure pump 120, and the second supply means. (200, air pump), and the ozone generating means 300 (micro plasma device) are operated, and the solenoid check valve 355 is opened. Accordingly, the raw water passing through the flow sensor 700 is delivered to the pressure pump 120 of the first supply means 100, and the pressure pump 120 pressurizes the raw water and supplies it to the mixing means 400. In addition, when the second supply means 200 (air pump) is operated, air is absorbed and supplied to the ozone generating means 300, and ozone gas is supplied from the supplied air while the ozone generating means 300 is operated. It is generated and supplied to the mixing means 400. In this case, the ozone gas may be supplied to the mixing means 400 through the open solenoid check valve 355.

Next, as shown in FIG. 7, ozone gas is sucked while raw water passes through the venturi pipe 410 of the mixing means 400, and ozone gas is dissolved in the raw water to generate ozone water. However, not all ozone gas is dissolved in raw water, and ozone gas that is not dissolved in raw water may remain. On the other hand, the mixing means 400 includes the first and second pressure reducing valves 420 and 430, and can adjust the pressure of the raw water flowing into the venturi pipe 410 with the first pressure reducing valve 420, and the second pressure reducing valve The pressure of the raw water discharged from the venturi pipe 410 can be adjusted with the valve 430. In this way, by adjusting the pressure of the raw water with the first and second pressure reducing valves 420 and 430, the amount of ozone gas sucked into the venturi pipe 410 can be controlled.

Next, as shown in FIG. 8, the ozone water generated by the mixing means 400 and the ozone gas not dissolved in the raw water are delivered to the spraying means 500, and the spraying means 500 supplies ozone water to agricultural products such as citrus fruits. Wash by spraying. In addition, ozone gas not dissolved in the raw water may be exhausted by the exhaust means 600. At this time, since the mixing means 400 continuously receives raw water and ozone, and generates ozone water continuously, the spraying means 500 may continuously spray and wash the ozone water on agricultural products such as citrus fruits.

Meanwhile, the apparatus for washing and treating agricultural products using ozonated water according to the present embodiment does not simply wash agricultural products such as citrus fruits using ozonated water. When washing using ozone water is completed, a waxing process may be performed after drying agricultural products such as citrus fruits. Here, in the waxing process, a waxing agent is sprayed onto agricultural products such as citrus through a nozzle. During the waxing process, an antibiotic material that reduces mold and bacteria may be sprayed together. Therefore, agricultural products such as citrus fruits are coated with antibacterial substances to reduce mold and bacteria, and eventually, it is possible to suppress the occurrence of spoilage. Although the agricultural product has been described as citrus fruits in the above description, this embodiment is not necessarily used only for citrus fruits, and can be used for all kinds of agricultural products that require cleaning or treatment.

Although the present invention has been described in detail through specific examples, this is for describing the present invention in detail, and the present invention is not limited thereto, and within the technical idea of the present invention, by those of ordinary skill in the art.
