Description
Technical Field
The invention belongs to the technical field of formaldehyde detection, and particularly relates to a device and a method for detecting formaldehyde in aquatic products.
Background
Some merchants in the aquatic product market can illegally soak water products by formalin (formaldehyde solution), so that the water products are preserved, the glossiness of the products is improved, the product selling period is prolonged, and the selling price is increased. According to the method, on one hand, the requirement on the sanitation and safety of aquatic products and food is not met, on the other hand, formaldehyde can be volatilized in the process that a merchant uses the formaldehyde solution, the content of formaldehyde in air can exceed the standard seriously and even, and people can inhale the volatilized formaldehyde gas in the purchasing process and are harmful to health.
The existing method for detecting the formaldehyde of the aquatic product is characterized in that a market supervisor detects the formaldehyde by utilizing the principle that the formaldehyde reacts with phloroglucinol to be orange-red under an alkaline condition, directly drips the soaking liquid of the aquatic product into a detection tube, adds a formaldehyde detection reagent, and then observes the color change condition. However, can receive the influence of surrounding environment when detecting, like when the trade company uses formaldehyde solution to soak in violation of rules and regulations, the aquatic products soak that its place position closes to also can consequently absorb a part of formaldehyde, and market supervisory personnel is through original mode, probably detects to close to trade company's soak and contains formaldehyde, can't guarantee the testing result accuracy, makes the trade company that is just being worked on consequently receive unreasonable punishment easily.
However, the detection method has a certain technical content, is difficult to implement by common users, and when a market supervisor goes to perform spot check detection, a merchant often takes corresponding measures in advance to perform the detection, so that the behavior of formaldehyde soaking of the merchant is difficult to perform spot check.
Therefore, an aquatic product formaldehyde detection device which is easy to implement by the general public and is simple to operate is urgently needed, so that people can detect automatically, find illegal merchants and report, and can avoid the influence of other factors in the market.

In order to achieve the purpose, the invention adopts the following technical scheme:
the aquatic product formaldehyde detection device comprises a detection box and a storage bin, wherein the detection box is separated into a detection chamber and an auxiliary chamber, the storage bin is arranged in the detection chamber, a circulating fan is further arranged in the detection chamber, the detection chamber is provided with an air inlet and an air outlet, the air inlet is sequentially provided with an air inlet formaldehyde purification module and an air inlet fan from outside to inside, and the air outlet is sequentially provided with an air outlet formaldehyde purification module and an air outlet fan from inside to outside; a formaldehyde sensor is further arranged on one side, close to the auxiliary chamber, in the detection chamber, and a PLC and a power supply module are arranged in the auxiliary chamber; the top of the detection box is provided with a display screen and a plurality of control buttons; the display screen, the control button, the formaldehyde sensor, the circulating fan, the air inlet fan and the air outlet fan are all electrically connected with the PLC; the storage bin is of a drawer type structure, is combined with the detection box in a sealing mode, and can be opened and closed manually; the storage bin is located in the detection chamber when being closed.
Preferably, the storage bin is a plastic product with an antibacterial function, so that bacteria can be prevented from breeding in a humid environment, and meanwhile, the storage bin is convenient to clean.
Preferably, the bottom of the storage bin is also provided with an electronic scale which is used for rechecking the weight of the aquatic products during formaldehyde detection, and when the device is arranged in the aquatic product market as a public facility by market monitoring personnel, the device not only can detect whether the aquatic products are soaked by formaldehyde, but also can monitor the nonstandard behaviors of aquatic product merchants on the weight of the aquatic products, and provides a favorable guarantee for safe and reasonable market supervision.
The invention also provides a detection method of the device, which comprises the following steps: put into the storing storehouse with aquatic products, and close sealed with the storing storehouse, make aquatic products be in the measuring chamber, open air intake fan by PLC control, the gas that will purify fills into the measuring chamber, open and continuously operate the circulating fan of settlement time, treat that circulating fan closes the back, formaldehyde sensor detects the indoor formaldehyde content of measuring and shows the testing result on the display screen, treat that there is the testing result to show the back, open air-out fan, will detect indoor gas and discharge after purifying, accomplish once and detect the circulation.
Preferably, the set time for the continuous operation of the circulating fan is 1-5 min.
Preferably, the PLC can set fixed time for the whole detection process, and a user can place aquatic products into the storage bin and the detection chamber, so that the subsequent steps can be automatically controlled, and the user can directly obtain a display result.
The basic control of the PLC and the power supply module to the display screen, the control button, the formaldehyde sensor, the circulating fan, the air inlet fan, the air outlet fan and the like can be realized by technical personnel in the field according to the idea of the invention without detailed description.
Compared with the prior art, the invention has the following beneficial effects:
the formaldehyde solution carried by the purchased aquatic products is volatilized, whether the aquatic products are soaked by the formaldehyde solution is determined, the amount of the formaldehyde solution carried by the aquatic products can be determined to a certain extent, and the aquatic products with excessive edible formaldehyde are avoided by treating the aquatic products according to the conditions before eating.
The detection mode of the formaldehyde sensor is adopted, so that the uncertainty of a detection result caused by the fact that the smell of people is greatly influenced by the surrounding environment and has strong subjectivity, and common people still cannot distinguish the formaldehyde smell and the like is reduced, and high technical content is not needed.
Air inlet department is equipped with air inlet formaldehyde purification module for avoid the influence of formaldehyde in the surrounding environment. This effect is not only the effect of the aquatic product soak, but may also include the effect of formaldehyde released by furniture, building materials, etc. in the environment near the detection bin.
Air outlet department is equipped with air-out formaldehyde purification module, prevents that the high concentration formaldehyde in the measuring room from discharging in the air on every side, causes the pollution, green for measurement personnel or surrounding environment.
Circulation fan's setting not only can keep detecting the indoor portion formaldehyde concentration homogeneous, can also flow through driving the air, accelerates volatilizing of aquatic products surface formaldehyde for the testing process improves detection efficiency.
The device can directly utilize the aquatic products bought from a merchant, directly places the aquatic products in the storage bin, is more secret compared with operations such as taking aquatic product soaking liquid, avoids the frustration of the merchant, protects the personal safety of a user, is simple to operate, has a good detection effect, is beneficial to the implementation of common people, can avoid the influence of a detection environment on a product detection result, and improves the accuracy of the detection result.
