propellerblandare

Propellerblandare, often translated as propeller mixer or propeller agitator, is a type of mechanical mixing device used in various industrial and laboratory applications. Its primary function is to create fluid motion and promote mixing within a liquid or gas. The core component of a propellerblandare is a propeller, typically made of metal or plastic, mounted on a shaft. This propeller is rotated by a motor, generating a flow pattern that draws material from the top and pushes it downwards, or vice versa, depending on the propeller's design and orientation.

These mixers are characterized by their high flow rate and relatively low shear. This means they are effective at moving large volumes of fluid and ensuring homogeneity, but they are less suitable for applications requiring the breaking down of solids or the creation of very fine dispersions. Propellerblandare are commonly used in tanks, vessels, and reactors for tasks such as blending, suspension of solids, heat transfer enhancement, and promoting chemical reactions. They are often employed in industries like water treatment, chemical processing, food and beverage production, and pharmaceuticals. The size and power of the propellerblandare are selected based on the volume of the fluid, its viscosity, and the desired mixing intensity.
