For the customs and grain storage industry, fumigation operations as an important means of pest control and protection of food and commodity quality, its safety and effectiveness can not be ignored. However, Yiyuntian, as a provider of the overall gas detection scheme, with its profound technical background and unremitting pursuit of innovation, has created a comprehensive and integrated gas detection solution for the customs and grain storage industry. With its excellent technical performance and wide application adaptability, Yiyuntian provides a solid technical support for the fumigation operation of customs supervision and grain storage.

1. scheme background

Customs measures fumigation gas to ensure the safety and effectiveness of the quarantine process, protect domestic natural resources and public health.

Fumigation is a 1 disinfection process for goods and their packaging, designed to protect native natural resources from alien species.This is the 1 kind of mandatory quarantine system. If the seller or freight forwarder does not have the corresponding awareness or reminder, it may lead to problems in customs declaration and inspection or terminal customs clearance, thus affecting the transportation time limit of the goods. Customs monitors the gas concentration in the fumigation process by using fumigation gas detectors, such as sulfuryl fluoride fumigation gas detectors, to ensure that the concentration value of the fumigation process does not exceed the safety standard, so as to ensure that the container fumigation quarantine can be carried out safely and efficiently. Such testing not only helps prevent harmful organisms from entering the country, but also prevents the spread of infectious diseases and protects the safety of agriculture, forestry, animal husbandry and fisheries.

In addition, as the mainstream mode of international cargo transportation, containers will inevitably cause the spread of bacteria and viruses, and even cause species invasion. Therefore, it is necessary to fumigate and sterilize the cabin and container of entry and exit. By detecting the fumigation gas, the customs ensures the implementation of this 1 process, thus effectively controlling the spread of diseases and pests, and protecting the safety of domestic public health and ecological environment.

2. Solutions

Before the export goods exit the customs, they need to be fumigated to kill harmful organisms and meet the quarantine standards of the importing country.The most commonly used fumigation method is curtain fumigation, but there may be fumigation leakage or uneven distribution of fumigant. In order to ensure the fumigation effect and personnel safety, the concentration of fumigant in the environment must be detected during fumigation and after fumigation. At present, the most commonly used fumigants in China are methyl bromide, sulfuryl fluoride and phosphine. Different fumigants use different fumigation objects. For all instruments and equipment containing copper, copper alloy, brass, gold and silver, decorations, clothing, undeveloped camera films, etc., phosphine fumigation is not suitable; Sulfuryl fluoride is not suitable for all edible or feed goods; precision electronic equipment, butter, lard, fat, automobiles, feathers, blankets, horsehair products, sweaters, man-made fibers, rubber products, magnesium products and other goods should not be fumigated with methyl bromide.

Fumigation gas detector for quarantine is mainly used for entry and exit customs, so the instrument must be easy to carry, simple to operate, no standard gas sample calibration is required for on-site detection, ordinary fumigation operators can also perform detection, and the reaction speed is fast, the test results can be obtained in a short period of time to meet the needs of fumigation adjustment at any time.For quarantine requirements, it is recommended to use portable pump suction type; pump suction type design, fast response speed; large capacity rechargeable battery design, can work continuously for a long time.
