Cooking fume in kitchen refers to the volatile organic matter and its heating decomposition produced in the process of food cooking and processing. With the rise of the tertiary industry, the food service industry is developing rapidly. However, the rapid development of the catering industry in the city also makes the lampblack pollution more and more serious. Kitchen smoke pollution will have a serious impact on the surrounding environment and human health.
Application of air quality PM2.5 sensor in restaurant kitchen smoke monitoring
Kitchen lampblack contains a lot of harmful substances and carcinogens. For example, the stink of lampblack can stimulate the nasal mucosa. Most of the catering industry is located in the industrial area, commercial area and residential area, part of which is located in the downstairs residential building. There is no single functional area. In addition, the vertical and horizontal streets between the buildings are uneven, the wind speed is small, which is not conducive to the spread of smoke, resulting in the low level of non-point source pollution is more harmful than the high point source pollution of industrial enterprises. It has a greater impact on people's normal life. In addition, the restaurant kitchen fume pollution also increases the operating cost of catering enterprises.
LUFTMY learned that at room temperature, the soot pollutants produced in the whole cooking process can be roughly divided into three categories. The first type is curable particles with a particle size greater than 10 microns. They are not affected by the earth's gravity and will not cause continuous pollution to the atmosphere. The second is the inhalable particles with particle size between 0.01 and 10 microns, most of which are PM2.5 fine particles discharged from food sources. The third category is mainly organic gaseous pollutants, which are important sources of volatile organic compounds (VOCs) and important precursors of complex regional pollution. More than 300 VOCs can be detected in food smoke. The emission of catering smoke will cause serious pollution to the atmosphere, so it is necessary to strengthen the supervision of catering smoke.
In recent years, the national regulations and penalties for cooking fume are more and more strict. How can catering companies avoid the punishment of kitchen fume emission? Then you need to know your own smoke emission indicators. Strengthening the detection and monitoring of lampblack can effectively help catering companies to understand the emission data of their own vents. If the standard exceeds the standard, we can find out and take measures to avoid environmental punishment in time! The most effective measure to monitor the kitchen oil smoke is to install air quality PM2.5 sensor, VOC sensor, formaldehyde sensor, etc. through these gas sensors, to monitor the oil smoke in real time and remind the staff to do well in ventilation and reduce the oil smoke pollution. Ld15 is recommended to be used by LUFTMY:
Overview of lefmai particle concentration detection sensor ld15:
Ld15 is a high-precision particle concentration sensor based on Mie scattering theory. It can continuously collect and calculate the number of suspended particles with different particle sizes in the air per unit volume, i.e. particle concentration distribution, and then convert it into mass concentration, and output it in the form of general digital interface. Ld15 has the characteristics of small volume, high precision, strong anti-interference, low power consumption, long service life and short response time of zero error alarm rate. This PM2.5 dust particle sensor can be embedded with various instruments or environmental improvement equipment related to the concentration of suspended particles in the air, such as lampblack, air detection equipment, air quality detection equipment, etc., to provide timely Accurate concentration data.
LUFTMY focuses on the research, production and sales of optical particle sensor technology. Guided by the corporate culture of "craftsmen build dreams" and adhering to the service tenet of "customer first", LUFTMY has occupied a high market share in the domestic and foreign markets of PM2.5 sensor. The PM2.5 microparticle sensor and other sensors are widely praised by the industry in measuring accuracy, stability, consistency error, anti-interference and other performance indicators.
