Description

A kind of lemon cleaning water preparation device system

technical field

The utility model relates to a device system for generating a sterilizing and disinfecting aqueous solution, in particular to a device system for preparing lemon cleaning water.

Background technique

Lemon is a kind of fruit, also known as lemon fruit, foreign lemon, and mother fruit. Lemon is rich in vitamin C, which can reduce phlegm and cough, promote body fluid and invigorate the stomach. It is used for bronchitis, whooping cough, loss of appetite, vitamin deficiency, heat stroke, polydipsia, etc. symptom. However, the texture of the lemon skin is more complicated, and it is easy to trap dust, and the lemon skin will secrete organic matter to form a package, which makes the surface of the lemon very easy to breed bacteria.

Lemons sold in the market usually need to be waxed on the surface of the lemons because of their long storage time. However, if the surface of the lemon originally contains dust or bacteria, it will be wrapped in it during the waxing process, and lemon, as a fruit that is directly soaked in water, is bound to have a serious impact. Therefore, how to effectively clean lemons and remove dust and bacteria attached to their surfaces has become the key to improving the edible value of lemons and protecting the interests of merchants and consumers.

Ordinary consumers can clean lemons in two simple ways. First, use warm water at 40-50 degrees Celsius, add a small amount of flour, soak for a few minutes, and then simply scrub clean. Second, rub the skin of the soaked lemon with salt, and use the fine particles of salt to completely remove the dust and bacteria on the surface of the lemon with constant friction. Special attention should be paid to the strength during the process. If the movement is too light, it will be difficult to achieve a sufficient friction effect. If the movement is too heavy, it may damage the skin of the lemon and cause the loss of nutrients in the skin of the lemon.

The above two methods are simple and effective when cleaning a small amount of lemons for ordinary consumers, but they cannot be realized for large-scale lemon growers. First of all, when the above two methods process lemons on a large scale, the cost will increase significantly; and the resource consumption is large, which is not environmentally friendly.

Sodium hypochlorite is a strong oxidant and has broad-spectrum bactericidal ability. Sodium hypochlorite solution can quickly kill various bacteria and viruses, such as Escherichia coli, fungi, Bacillus subtilis, Staphylococcus aureus, etc., and can destroy the surface antigen of hepatitis virus. It can sterilize, deodorize, and bleach tableware, tea sets, and bath sets. Sodium hypochlorite is widely used as a disinfectant or deodorant for vegetables, fruits, farms and livestock houses in agriculture and animal husbandry, and has excellent sterilization and disinfection effects.

The existing sodium hypochlorite disinfection method is generally to obtain a sodium hypochlorite solution by electrolyzing an aqueous solution of sodium chloride, and using it in various scenarios that require disinfection. The chemical reaction formula of electrolytic salt solution is as follows:

2NaCl+2H ₂ O= ^power =2NaOH+H ₂ ↑+Cl ₂ ↑ 2NaOH + Cl ₂ ==NaCl + NaClO + H ₂ O

Sodium chlorate solution will decompose when exposed to light during use: 2NaClO= ^light\heat =2NaCl+O₂↑

And this reaction is an irreversible reaction. During the electrolysis of sodium chloride, the hydrogen ions in the water obtain electrons at the cathode to form hydrogen gas, which destroys the ionization balance of the water and forms a large number of hydroxide ions at the cathode. The calcium and magnesium ions in the water will react with the hydroxide ions , produce hydroxides that are insoluble in water, and form dirt on the electrode, hindering the progress of the electrolysis reaction. At the same time, in the process of electrolyzing the sodium chloride solution, the anode will also undergo electron loss corrosion reaction.

In addition, during the preparation process of the sodium hypochlorite disinfection solution, the quality of the aqueous solution for disinfection and cleaning must be strictly controlled, and impurities must not be mixed. Because in the process of electrochemical reaction, the electric field at the electrode is very strong, once any impurity is close to the electric field, it will cause serious damage to the equipment, ranging from power failure to shutdown of the system, to serious damage to the circuit system. If the stability and reliability of the electrolytic reaction process in the electrochemical processor is effectively improved, it has also become a major difficulty in the preparation of sodium hypochlorite disinfection solution. Although some people propose to use filters to remove impurities, due to the limitation of the filter's service life, it is necessary to send special personnel to maintain it regularly, which increases the operating cost of the system. The cost also increases accordingly.

Therefore, how to effectively apply the sodium hypochlorite disinfection method to the lemon cleaning process requires further research to provide reliable equipment. Especially for the large-scale cleaning of lemon fruit, how to ensure the stable operation of the equipment for preparing sodium hypochlorite and ensure that the cleaning solution is more suitable for cleaning and removing the deposited dust and bacteria on the lemon has become an urgent problem to be solved in the lemon cleaning work.

Below it is the electrolyzed water inlet pipe 7, and the two electrolyzed water processors all draw the aqueous solution to be electrolyzed from the pipe 7. Electrolyzed water outlet pipes 6 are arranged on the sides of the two electrolyzed water processors, and the sodium hypochlorite solution prepared by electrolysis of the electrolyzed water processors flows into the pipe 6, and flows out from the electrolyzed water outlet pipe outlet 10 at the end of the pipe 6, correspondingly Sodium hypochlorite solution can be used to clean various fruits and vegetables to achieve disinfection and sterilization.

Further, inner wire ball valves 8a, 8b, 9a, 9b are provided on the connecting pipes connecting the first electrolyzed water processor 8 and the second electrolyzed water processor 9 to the electrolyzed water inlet pipe 7 and the electrolyzed water outlet pipe 6 . When the amount of disinfecting water to be prepared is small, only one of the electrolyzed water processors needs to be turned on, such as closing the inner wire ball valves 9a, 9b, opening the inner wire ball valves 8a, 8b, and the first electrolyzed water processor 8 is running. While the second electrolyzed water processor 9 is not in operation, the first electrolyzed water processor is implemented to electrolyze the sodium chloride aqueous solution to prepare a disinfection solution containing sodium hypochlorite.

Fig. 2 is a front view of the utility model. The technical scheme of the utility model can be further understood in conjunction with Fig. 1-2.
