Centrifugal atomizers are a very widely used process in the liquid forming and drying industry for producing powdered and granular solid products from solutions, emulsions, suspensions and plastic paste-like liquid materials. Therefore, the particle size distribution, residual moisture, bulk density and particle shape of the finished product must meet precise criteria. Spray drying is a highly desirable process.
Working principle of centrifugal atomizer: The centrifugal atomizer is the component of the spray drying unit that enables the atomizing medium to obtain high energy and high velocity, and is also the key component that plays an important role in atomization efficiency and stability of the atomization process. It uses an electric motor to drive a large gear through a coupling that engages with a pinion on a rotating shaft. The gear shaft after the first stage speed-up drives the second stage large gear to achieve high speed rotation. When the raw material liquid enters the feed tube of the centrifugal atomizer, it flows evenly through the raw material liquid distribution plate into the high-speed rotating spray plate, and the raw material liquid is sprayed into very small atomized droplets, which greatly increases the surface area of the material. Material liquid. The hot air in the drying chamber evaporates rapidly and can be dried into finished products in a very short time.
