Stainless steel wind knife is a commonly used fluid mechanical device, and its working principle is based on the Coaster effect (also known as the wall effect), which means that when there is surface friction between the fluid (water flow or air flow) and the surface of the object it flows through, the flow velocity of the fluid will slow down. As long as the curvature of the surface of the object is not too large, the fluid will leave its original flow direction and instead adhere to the protruding surface of the object, ultimately forming the phenomenon of fluid being adsorbed and flowing on the surface of the object.

In a stainless steel wind blade, compressed air enters the blade and is blown out at high speed with a thin airflow sheet with a thickness of only 0.05 millimeters on one side. Through the Coaster effect and the special geometric shape of the wind blade, this thin film air curtain can draw in up to 30 to 40 times the ambient air, forming a thin, high-intensity, and high airflow impact air curtain. Wind knives are divided into two types based on their working modes: standard wind knives and super wind knives. The wind curtain of the standard wind knife deflects 90 degrees and blows out, while the wind curtain of the super wind knife blows out horizontally.

Stainless steel wind knives are widely used in various scenarios due to their high strength, corrosion resistance, and good stability. In the food processing industry, stainless steel air knives can be used for cutting, processing, and packaging food such as meat, vegetables, fruits, etc. By adjusting the parameters and structure of the air knife, precise processing and handling of different foods can be achieved. In the pharmaceutical manufacturing industry, stainless steel air knives are commonly used for mixing pharmaceutical raw materials, cleaning and disinfecting pharmaceutical equipment, and other processes to improve the quality and safety of drugs. In addition, stainless steel wind knives are widely used in the chemical industry, environmental protection, agriculture, and metal industry.
