Industry background:

-The importance of food security: Food is the basic material of human life, related to national economy and people's livelihood. As an important place for food storage, the safety and stability of grain warehouses are crucial.

-The necessity of fumigation operation: During grain storage, in order to prevent and control harmful organisms such as pests and molds, and extend the storage period of grain, grain warehouse fumigation is a common and effective means. Commonly used fumigants include phosphine, bromomethane, sulfuryl fluoride, etc.

-The hazards of fumigation gases: These fumigants are toxic gases that not only kill pests, but also cause toxic pulmonary edema and respiratory failure, such as phosphine. Bromomethane may cause neurological damage, liver damage, etc., posing potential hazards to human health and potentially polluting the environment, affecting ecological balance.

-The shortcomings of traditional monitoring: In the past, grain warehouse management was mostly manually monitored, such as grain situation and temperature, which required frequent inspections by custodians. The workload was high and the monitoring results were not accurate, making it difficult to grasp key information such as fumigation gas concentration in real time and accurately.

-The promotion of technological development: With the advancement of technology, sensor technology, spectral analysis technology, and gas chromatography technology continue to develop, providing technical support for real-time monitoring and quantitative analysis of fumigation gases in grain warehouses, making it possible to develop and apply monitoring and control systems for fumigation and disinfection gases in grain warehouses.

Solution for monitoring and controlling fumigation and disinfection gases in grain warehouses:

According to the demand for online detection of grain warehouses, the Beidou Star Instrument T-BD5IMD-IR4812 series fixed gas detector can be matched with gas/temperature and humidity detection according to on-site needs, and can detect various gas indicators such as temperature/humidity, sulfuryl fluoride, bromomethane, phosphine, oxygen, etc. It supports powder and dust detection function. The core of the product adoptsOriginal importGas sensors are easy to install and can be wall mounted on site. Users only need to connect DC24V power supply to detect target gases. According to the different needs of customers, the monitoring range, sampling method, output signal, linkage equipment, alarm function, etc. of the instrument can be customized. It can also be used in conjunction with the Beidou Star Instrument CPT2000 series alarm controller. According to the usage requirements, it can be used in a split line or bus system. All monitored target gases can be installed in the alarm controller for unified display and alarm, etc.
