Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable preservation equipment technology, and in particular to an integrated machine for fruit and vegetable preservation. Background Technology

[0002] Fruit and vegetable storage facilities are places where fresh fruits and vegetables are stored. Environmental factors such as humidity, gas composition, and microorganisms greatly affect the freshness of these produce. For example, fresh fruits and vegetables have a high water content. If the humidity in the storage environment is too low, the water will evaporate into the environment, causing the fruits and vegetables to wilt, affecting normal metabolism, accelerating tissue aging, and consequently reducing their storage resistance and disease resistance, thus shortening their shelf life. Ethylene in the gaseous components promotes ripening and aging of fruits and vegetables, accelerates quality decline, deteriorates flavor, and even leads to rot, thus affecting their storage period. Various bacteria, molds, viruses, and other microorganisms can cause spoilage and deterioration of fruits and vegetables.

[0003] Therefore, in order to extend the shelf life of fruits and vegetables and maintain their freshness and quality, humidifiers or sterilizers are usually placed in the fruit and vegetable storage room. However, placing multiple devices in the storage room at the same time takes up a lot of space; and having each device placed separately for use and control is inconvenient.

[0004] Therefore, there is an urgent need to develop an integrated machine for preserving fruits and vegetables to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated machine for preserving fruits and vegetables, which integrates humidification, ethylene removal and sterilization, and is highly integrated, easy to use and occupies little space.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An all-in-one machine for preserving fruits and vegetables includes:

[0008] The unit housing includes a first housing and a second housing, wherein the first housing has an air inlet and an air outlet, and the second housing has a gas outlet.

[0009] A humidification assembly, comprising a water tank, an atomizer, and a first fan, wherein the water tank is located outside the unit housing, the atomizer is located inside the water tank and is capable of turning the water in the water tank into water mist, and the first fan is installed in the water tank and is capable of blowing the water mist out of the water tank;

[0010] The removal component is located inside the first housing. The removal component includes a first adsorption tank, a second adsorption tank, and a second fan. One end of the second fan is connected to the air inlet, and the other end is connected to the first adsorption tank and the second adsorption tank respectively. The first adsorption tank and the second adsorption tank respectively contain ethylene adsorbent and activated carbon adsorbent. The outlets of the first adsorption tank and the second adsorption tank are respectively connected to the air outlet.

[0011] A sterilization component is located within the second housing. The sterilization component includes an ozone generator capable of producing ozone, and the ozone outlet of the ozone generator is connected to the gas outlet.

[0012] As an optional technical solution for an integrated machine for preserving fruits and vegetables, the first housing and the second housing are arranged sequentially in a vertical direction, with the second housing located on top of the first housing.

[0013] As an optional technical solution for an integrated machine for preserving fruits and vegetables, the water tank is located on the outer wall of the first housing.

[0014] As an optional technical solution for an integrated machine for preserving fruits and vegetables, the humidification component also includes a filter, which is located at the water inlet of the water tank.

[0015] As an optional technical solution for an integrated machine for preserving fruits and vegetables, the humidification module also includes a water pump, which is located at the bottom of the water tank, and the atomizer is located in the middle of the water tank. The water pump is connected to the atomizer through a hose, and the top of the water tank is provided with a mist outlet.

[0016] As an optional technical solution for an integrated machine for preserving fruits and vegetables, the humidification module also includes a flared mouth, which is located at the mist outlet.

[0017] As an optional technical solution for an integrated machine for preserving fruits and vegetables, the humidification component also includes a float level switch for controlling the water level in the water tank so that the water level in the water tank does not exceed the atomizer.

[0018] As an optional technical solution for an integrated machine for preserving fruits and vegetables, the first fan is located on top of the water tank.

[0019] As an optional technical solution for integrated fruit and vegetable preservation machines, the integrated fruit and vegetable preservation machine also includes an electrical control component, which includes an electrical control box and an environmental sensing component. The electrical control box is located outside the unit casing, and the environmental sensing component is located inside the preservation chamber and is electrically connected to the electrical control box.

[0020] As an optional technical solution for integrated fruit and vegetable preservation machines, the environmental sensing components include a humidity sensor, a carbon dioxide sensor, an ethylene sensor, and an ozone sensor.

[0021] The beneficial effects of this invention are:

[0022] The integrated fruit and vegetable preservation machine provided by this invention includes a unit shell, a humidification component, a desiccant component, and a sterilization component. The unit shell includes a first shell and a second shell, serving to support and house the humidification component, the desiccant component, and the sterilization component. The humidification component includes a water tank, an atomizer, and a first fan. The first fan blows the water mist generated by the atomizer out of the water tank and into the preservation chamber to humidify and preserve the fruits and vegetables.

The desiccant component includes a first adsorption tank, a second adsorption tank, and a second fan. The first and second adsorption tanks respectively contain ethylene adsorbent and activated carbon adsorbent. Using the second fan as a power source, the gas in the preservation chamber is forced through the first and second adsorption tanks from the air inlet. Ethylene reacts chemically with the ethylene adsorbent in the first adsorption tank, while harmful gases or impurities react with the activated carbon adsorbent in the second adsorption tank, thereby achieving the purpose of removing ethylene and purifying the ambient air. The sterilization components include an ozone generator, which produces ozone that can be released into the cold storage to sterilize fruits and vegetables.

[0023] Therefore, this integrated fruit and vegetable preservation machine combines humidification, ethylene removal, and sterilization into one unit, making it highly integrated, easy to use, and space-saving. Attached Figure Description

[0035] This embodiment provides an integrated machine for preserving fruits and vegetables. This integrated machine combines humidification, ethylene removal, and sterilization, and is highly integrated, easy to use, and occupies little space.

[0036] Specifically, such as Figures 1 to 5 As shown, the integrated fruit and vegetable preservation machine includes a unit housing 100, a humidification component 200, a desiccant component 300, and a sterilization component 400. The unit housing 100 includes a first housing 110 and a second housing 120. The first housing 110 has an air inlet 111 and an air outlet 112, both of which are louvered. The second housing 120 has a gas outlet 121. The humidification component 200 includes a water tank 210, an atomizer 220, and a first fan 230. The water tank 210 is located outside the unit housing 100, the atomizer 220 is located inside the water tank 210 and can atomize the water in the water tank 210 into a water mist, and the first fan 230 is installed in the water tank 210 and can blow the water mist out of the water tank 210. The removal component 300 is located inside the first housing 110. The removal component 300 includes a first adsorption tank 310, a second adsorption tank 320, and a second fan 330. One end of the second fan 330 is connected to the air inlet 111, and the other end is connected to both the first adsorption tank 310 and the second adsorption tank 320. The first adsorption tank 310 and the second adsorption tank 320 contain ethylene adsorbent and activated carbon adsorbent, respectively. The outlets of the first adsorption tank 310 and the second adsorption tank 320 are connected to the air outlet 112. The sterilization component 400 is located inside the second housing 120. The sterilization component 400 includes an ozone generator 410, which generates ozone. The ozone outlet of the ozone generator 410 is connected to the gas outlet 121.

[0037] Based on the above design, the unit housing 100 includes a first housing 110 and a second housing 120, which support and accommodate the humidification component 200, the desiccant component 300, and the sterilization component 400. The humidification component 200 includes a water tank 210, an atomizer 220, and a first fan 230. The first fan 230 can blow the water mist generated by the atomizer 220 out of the water tank 210 and into the cold storage to humidify and preserve fruits and vegetables. The water tank 210 is located on the outside of the unit housing 100, which facilitates water filling and daily maintenance of the water tank 210, and also prevents the generated water mist from affecting the operation of the components inside the unit housing 100. The ethylene removal component 300 includes a first adsorption tank 310, a second adsorption tank 320, and a second fan 330. The first adsorption tank 310 and the second adsorption tank 320 respectively contain ethylene adsorbent and activated carbon adsorbent. Using the second fan 330 as a power source, the gas in the cold storage is forced through the first adsorption tank 310 and the second adsorption tank 320 from the air inlet 111. Ethylene reacts chemically with the ethylene adsorbent in the first adsorption tank 310, while harmful gases or impurities react with the activated carbon adsorbent in the second adsorption tank 320, thereby achieving the purpose of removing ethylene and purifying the ambient air. The sterilization component 400 includes an ozone generator 410, which generates ozone that can be discharged into the cold storage to sterilize fruits and vegetables. Therefore, this integrated fruit and vegetable preservation machine combines humidification, ethylene removal, and sterilization into one unit, offering high integration, ease of use, and a small footprint.

[0038] Optionally, the ozone generator 410 includes a circuit board and a reaction plate, etc. It uses a high-voltage current of a certain frequency to create a high-voltage corona electric field, causing the oxygen molecules in and around the electric field to undergo an electrochemical reaction to produce ozone, thereby killing microorganisms. The ozone output of the ozone generator 410 is 1g / h.

[0039] Optionally, the integrated fruit and vegetable preservation machine also includes an electrical control component, which includes an electrical control box 510 and an environmental sensing component. The electrical control box 510 is located outside the unit casing 100, while the environmental sensing component is located inside the preservation chamber and is electrically connected to the electrical control box 510. The electrical control box 510 is independent of the unit casing 100 and consists of electrical components such as a PLC, a touch screen, circuit breakers, relays, and indicator lights, as well as a housing. The PLC controls various functions, and the touch screen on the control box 510 panel allows operation of various device processes, display of relevant data processed by the PLC, setting of various control parameters, and recording, storing, and querying of important data (equipment operating status, various system fault alarms), thereby realizing the automatic control and management of the integrated fruit and vegetable preservation machine. The environmental sensing component is used to monitor the storage environment information in the preservation chamber.

[0040] In this embodiment, the electrical control box 510 has dimensions of 500mm×800mm×280mm and a power of 3kW.

[0041] Furthermore, the environmental sensing components include a humidity sensor 521, a carbon dioxide sensor 522, an ethylene sensor 523, and an ozone sensor 524. These sensors are placed in corresponding positions within the cold storage room and connected to the electrical control box 510 via wiring. They are used to detect information such as humidity, carbon dioxide concentration, ethylene concentration, and equipment status within the cold storage room, and transmit this information to the electrical control box 510 via the Profinet fieldbus. Simultaneously, they receive control commands from the electrical control box 510 to control the opening and closing of the humidification component 200, the desiccant component 300, the sterilization component 400, and the valve component 600.

[0042] Specifically, the valve assembly 600 includes a first electric valve, a second electric valve, a third electric valve, and a fourth electric valve. The first electric valve is located at the front end of the air inlet 111 and controls the opening and closing of the air inlet 111. The second electric valve is located at the air outlet of the first adsorption tank 310. The third electric valve is located at the air outlet of the second adsorption tank 320. The fourth electric valve is located at the air outlet of the ozone generator 410.

[0043] Furthermore, the electrical control box 510 has operation, query, and personnel protection functions. A limit switch is installed at the entrance of the cold storage room. This switch signal enters the system and is interlocked with the equipment operation. When personnel open the door, the system automatically stops the equipment to ensure a comfortable and safe operating environment for personnel inside the cold storage room. In addition, there are equipment protection functions, including a second overload alarm, ozone generator 410 fault alarm, water tank 210 high water level alarm, ozone concentration high alarm, cold storage room door interlock shutdown protection function, atomizer plate replacement reminder for atomizer 220, ethylene adsorbent replacement reminder, activated carbon adsorbent replacement reminder, and ozone generator 410 reaction plate replacement reminder. In the event of a fault, the integrated fruit and vegetable preservation machine will issue an alarm signal and automatically shut down.

[0044] Optionally, the first housing 110 and the second housing 120 are arranged in sequence along the vertical direction, and the stacked arrangement saves space; the second housing 120 is located on top of the first housing 110, and the first adsorption tank 310 and the second adsorption tank 320 are relatively large. Placing the first housing 110, which contains the humidification component 200, at the bottom is beneficial to the stability of the integrated machine for fruit and vegetable preservation.

[0045] Specifically, the bottom of the first housing 110 is provided with a mounting rack, and the integrated fruit and vegetable preservation machine is placed on the ground through the mounting rack.

[0046] In this embodiment, the first housing 110 is provided with a first operating port 113 and a second operating port 114. The first operating port 113 and the second operating port 114 are respectively directly opposite the first adsorption tank 310 and the second adsorption tank 320. Specifically, the front surface of the first housing 110 (i.e. the side facing the operator, and the water tank 210 is located on the left and right side of the unit housing 100) is used to operate and observe the adsorption process of the first adsorption tank 310 and the second adsorption tank 320.

[0047] Furthermore, to further enhance the overall stability of the integrated fruit and vegetable preservation machine and prevent it from tipping over, the water tank 210 is located on the outer wall of the first housing 110. Optionally, the water inlet 211 of the water tank 210 is connected to a water source or can be manually filled with water.

[0048] Optionally, the humidification assembly 200 also includes a filter 212 located at the water inlet 211 of the water tank 210 to filter the water entering the water tank 210 and prevent clogging of the downstream atomizer 220.

[0049] Optionally, the humidification module also includes a water pump 250, which is located at the bottom of the water tank 210, and an atomizer 220 is located in the middle of the water tank 210. The water pump 250 is connected to the atomizer 220 through a hose. The top of the water tank 210 is provided with a mist outlet. The water pump 250 draws water to the atomizer 220 for atomization, and the water mist is sprayed out from the mist outlet at the top of the water tank 210, and the spray is smooth.

[0050] Furthermore, the humidification module also includes a horn 240, which is located at the mist outlet. The special shape of the horn 240 enhances the mist spraying effect.

[0051] The humidification assembly 200 also includes a float level switch for controlling the water level in the water tank 210 so that the water level in the water tank 210 does not exceed the atomizer 220.

[0052] It should be noted that a shut-off valve is provided at the front end of the water inlet 211, which is used to start or stop water replenishment to the water tank 210.

[0053] Furthermore, the first fan 230 is located at the top of the water tank 210, which is actually the highest point of the water tank 210, to blow the water mist to the outside to the maximum extent.

[0054] In this embodiment, the humidification component 200 produces 4 kg / h of mist, with a mist particle diameter of less than 10 μm. The atomizer 220 has a water supply pressure of 0.1 MPa-0.6 MPa, and the water tank 210 is automatically replenished, achieving adjustable humidity levels of 70%-95% in the cold storage room, with real-time humidity control. The second fan 330 of the de-icing component 300 has an air volume of 48 m³ / h and a static pressure of 5000 Pa, controlling the ethylene concentration in the cold storage room to not exceed 2 ppm.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
