Centrifugal
Spray Dryers in spray dryers, the specific aspects that will be dealt with in the following, are three examples of the atomization of the
Dryer, so that everyone can have a deep understanding, in this kind of dryer, and at the same time, also You can use this article to promote the learning process of the site's products and increase your expertise in this area. Centrifugal
Spray Dryer, a kind of dryer, its three kinds of atomization, or its three forms, specifically, is:
The atomization form is as follows: the material liquid is directly split into droplets. If the feed amount of the liquid in the centrifugal spray dryer is relatively small, since it is subjected to a centrifugal force, it will quickly move toward the edge of the dispersion disk and the liquid bulging above it. The ring is related to the viscosity of the feed liquid, surface tension, centrifugal force, and the shape and smoothness of the dispersion disc. If the centrifugal force is greater than the surface tension of the droplets, the spherical droplets will be rapidly split and atomized, but there will be a small amount of large droplets. The
Atomization Form 2: Filament split into droplets If the feed rate of the centrifugal spray dryer is relatively large, and the speed of the dispersion disk is relatively fast, then the hemispherical droplet above it will be drawn into a filamentous liquid line. . And, there is a direct relationship between them. However, when a certain amount is reached, the liquid line becomes thicker, and the amount of the liquid line does not increase any longer. At this time, the liquid line will break, and then it shrinks into a spherical shape. The
Atomization Form 3: Membrane Splitting into Droplets When the centrifugal spray dryer is in operation, the liquid flow continues to increase, but the liquid filament and wire diameter no longer increase, then, the adhesive between the liquid filaments will form a thin film. When it is thrown by centrifugal force and has a certain distance from the dispersing disc, it will form droplets and have a wider distribution. If the speed is further increased, the liquid can be ejected at high speed and then atomized.
