Description

Technical Field

[0001] The present invention relates to the technical field of fumigation equipment, and in particular to a fumigation equipment and application thereof. Background Art

[0002] As people's living standards improve, they pay more and more attention to the nutritional value, good taste and flavor of potatoes. However, potatoes are very easy to spoil and deteriorate due to improper harvesting, their own physiological metabolism, microbial infection and mechanical damage after harvesting, and are not resistant to storage. Therefore, the research and application of potato preservation technology is particularly important. In recent years, many domestic and foreign scholars have studied potato preservation technology. The preservation of potatoes is mainly through adjusting the ambient temperature, humidity, pressure and gas composition, aiming to extend the shelf life of potatoes. This preservation method is not easy to control and requires large instruments. There are also natural or synthetic preservatives that are used to soak and coat potatoes to extend the shelf life of potatoes. Such methods are cumbersome, costly and have chemical residues, which are easy to cause harm to the human body. Therefore, it is particularly important to seek a method that is easy to operate, pollution-free, and residue-free. Fumigation technology acts on potatoes by causing the fumigant to disperse quickly and evenly in a confined space, and by controlling enzyme activity and inhibiting the growth of harmful bacteria, it can extend the shelf life of potatoes and better ensure the quality of potatoes during storage. This treatment method does not come into direct contact with potatoes, so the toxic effect of this technology on potatoes and the human body is relatively small, and it is easy to operate, and is considered to be a new type of preservation method.

[0003] In addition, potato seedling substrate is needed in the planting process. Commonly used seedling substrate is made of raw materials such as soil, peat and vermiculite, and fertilizer. The seedling substrate usually carries some bacteria or insect eggs after use and cannot be used again for seedling cultivation. However, if it is discarded at will, it will affect the surrounding environment and threaten human health, and the nutrients remaining in the seedling substrate after discarding will also be wasted. If it is fumigated and disinfected to kill harmful bacteria and insect eggs, it can be reused for seedling cultivation again.

[0004] Therefore, fumigation equipment is required for both potato fumigation preservation and seedling medium fumigation disinfection. However, the current fumigation equipment has problems of uneven fumigation and poor fumigation effect. In addition, the existing fumigation equipment does not clean the potatoes before fumigation, and the soil on the potato surface will also affect the fumigation effect.

[0005] Therefore, providing a fumigation device with a cleaning function to improve the fumigation effect has become an urgent problem to be solved. Summary of the invention

The nozzle 1504 sprays water onto the surface of the object to be smoked to clean the soil on the surface of the object to be smoked or to disinfect it. The excess water will fall onto the drainage plate 17, and the water will be introduced into the drain port 12 through the drainage plate 17 to recycle the waste water. The cleaned material to be fumigated will fall into the material box 4 at the end of the conveyor belt 1407. The bottom wall of the material box 4 is composed of a sieve plate 41, which will control excess moisture. After the material box 4 is full, the technician opens the door 1801 to take out the material box 4, puts it into the fumigation chamber 21, puts the medicine into the medicine box 3 and turns on the motor 23 to start stirring the medicine, turns on the heating wire 38 to heat the medicine into steam, and the steam passes through the pump 26, the main pipe 23 and the fumigation pipe 25 in turn, and fumigates from the top and bottom of the material to be fumigated at the same time. The steam is treated with the adsorbent in the adsorption tube 211 and then discharged. After the fumigation is completed, the technician opens the door 28 to take out the material box 4, pours out the material to be fumigated, and then puts the empty material box 4 into the material box mounting seat 16 again to continue loading the material to be fumigated.

[0042] Example 1

[0043] Food to be smoked: potatoes;

[0044] Fumigant: ethanol (characteristics: volatile at room temperature);

[0045] The substance in the liquid tank 1501 is clean water.

[0046] Fumigation process: Put the potatoes into the feeding port 11, and they fall onto the conveyor belt 1407 under the guidance of the feeding plate 111. Then turn on the pump 1502, and clean water starts to wash and rinse the soil on the surface of the potatoes. The conveyor belt 1407 sends the potatoes to the material box 4, and after the material box 4 is full, it is placed in the fumigation chamber. Put ethanol into the medicine box 3. When the room temperature is high (25-30℃), the heating wire 38 can be turned on. When the room temperature is low (<25℃), the heating wire 38 can be turned on to heat the ethanol solution to 45℃ to improve the evaporation efficiency of ethanol. Fumigating potatoes with ethanol vapor can not only kill and avoid bacteria, but also effectively inhibit the greening of potatoes. The most important thing is that ethanol is green and safe for the human body and the environment, and there is no need to worry about pesticide residues and steam pollution.

[0047] Example 2

[0048] Food to be smoked: potatoes;

[0049] Fumigant: ethanol (characteristics: volatile at room temperature) + thyme essential oil (characteristics: volatile at room temperature);

[0050] The substance in the liquid tank 1501 is clean water.

[0051] Fumigation process: put potatoes into the feeding port 11, and fall on the conveyor belt 1407 through the guidance of the feeding plate 111, then turn on the pump 1502, clean water starts to clean and rinse the soil on the surface of the potatoes, and the conveyor belt 1407 delivers the potatoes to the material box 4, and puts them into the fumigation chamber after the material box 4 is filled. Put ethanol and thyme essential oil into the medicine box 3, turn on the motor 2 33 and start stirring, because thyme essential oil is volatile at room temperature, so when the room temperature is high (25-30 ℃), the heating wire 38 can not be turned on, and when the room temperature is low (<25 ℃), the heating wire 38 can be turned on, and the mixed solution is heated to 45 ℃ to improve the evaporation efficiency of thyme essential oil. Fumigating potatoes with thyme essential oil can not only effectively inhibit the activity of polyphenol oxidase and inhibit browning, but the most important thing is that thyme essential oil is green and safe to human body and environment, and there is no need to worry about pesticide residues and steam pollution environmental problems.

[0052] Example 3

[0053] Food to be smoked: potatoes;

[0054] Fumigant: ethanol (characteristic: volatile at room temperature) + polyvinyl alcohol (characteristic: not volatile at room temperature);

[0055] The substance in the liquid tank 1501 is clean water.

[0056] Fumigation process: Put the potatoes into the feeding port 11, and they will fall onto the conveyor belt 1407 under the guidance of the feeding plate 111. Then turn on the pump 1502, and clean water will start to wash and rinse the soil on the surface of the potatoes. The conveyor belt 1407 will send the potatoes to the material box 4, and put them into the fumigation chamber after the material box 4 is full. Put ethanol and polyvinyl alcohol into the medicine box 3, turn on the motor 2 33 to start stirring. Because polyvinyl alcohol is not easy to volatilize, it is necessary to turn on the heating wire 38 to heat the mixed solution to 48°C to improve the evaporation efficiency of polyvinyl alcohol. Fumigating potatoes with polyvinyl alcohol vapor can reduce the evaporation of surface water, maintain the freshness and taste of potatoes, and thus extend the shelf life of potatoes. Most importantly, ethanol and polyvinyl alcohol are green and safe for human body and environment, and there is no need to worry about pesticide residues and steam pollution.

[0059] Fumigant: 45% chlorothalonil fumigant;

[0060] The substance in the liquid tank 1501 is an ethanol solution with a volume fraction of 75%.

[0061] Fumigation process: Put the potatoes into the feeding port 11, and they fall onto the conveyor belt 1407 under the guidance of the feeding plate 111. Then turn on the pump 1502. The ethanol solution washes the soil on the surface of the potatoes and also preliminarily disinfects the surface of the potatoes. The conveyor belt 1407 sends the potatoes to the material box 4. After the material box 4 is full, it is put into the fumigation chamber. Put the chlorothalonil fumigant into the medicine box 3, turn on the heating wire 38, heat the chlorothalonil fumigant to make it self-ignite, and fumigate the potatoes with smoke. A mixture of activated carbon and aluminum oxide is used as the adsorbent in the adsorption tube 11 to treat the smoke released by the combustion of chlorothalonil.

The conveyor belt 1407 delivers the potatoes to the material box 4. After the material box 4 is full, it is placed in the fumigation chamber. Put the antifungal smoke agent into the medicine box 3, turn on the heating wire 38, and fumigate the potatoes with the smoke from the burning antifungal smoke agent. A mixture of activated carbon and alumina is used as the adsorbent in the adsorption tube 11 to treat the smoke generated by the burning of the antifungal smoke agent.

Put the potassium permanganate solution into the medicine box 3, and then put the formaldehyde solution into the medicine box 3. Because potassium permanganate and formaldehyde react quickly, the heating wire 38 can be turned off, or the heating wire 38 can be turned on in advance to heat the potassium permanganate solution to 45°C before adding the formaldehyde solution to improve the reaction efficiency. Most importantly, the carbon dioxide generated by the reaction is harmless to the environment.
