In pneumatic conveying, dilute phase conveying refers to the low concentration of solid particles in the airflow, with less interaction between particles, similar to suspended particles in gas. Dilute phase pneumatic conveying has a wide range of application fields, such as material conveying in industries such as lithium batteries, chemicals, plastics, food, pharmaceuticals, metallurgy, and electricity.　　Dilute phase pneumatic conveying has been widely used in the chemical industry. For example, in chemical production, it is necessary to transport and mix various raw materials, intermediates, finished products, and other materials. Dilute phase pneumatic conveying can achieve fast and efficient material transportation, while also avoiding possible problems such as wear and leakage during mechanical conveying, thereby ensuring the continuity and stability of the production process.　　In the food industry, dilute phase pneumatic conveying is also widely used for conveying powdered and granular materials. For example, in the production processes of powder making, pharmaceuticals, sugar making, etc., various raw materials need to be mixed, transported, and packaged. Dilute phase pneumatic conveying can ensure that materials are not contaminated or spoiled during the conveying process, thereby ensuring the quality and safety of food.
