Schneckenrührwerk

Schneckenrührwerk, also known as screw agitator or helical ribbon agitator, is a type of industrial mixer used for agitating liquids and viscous materials. It consists of one or more helical ribbons or screws rotating on a central shaft. The design of the Schneckenrührwerk allows for efficient mixing, especially in tanks with high viscosity or shear-sensitive products. The helical shape of the ribbons moves the material axially within the tank, promoting thorough blending and preventing stratification.

These agitators are commonly employed in various industries, including chemical processing, food and beverage production, pharmaceuticals, and wastewater treatment. They are particularly effective for applications requiring gentle mixing, homogenization, and heat transfer. The specific configuration of the Schneckenrührwerk, including the number of ribbons, their pitch, and the shaft diameter, can be customized to suit the particular properties of the medium being agitated and the desired mixing outcome.

The Schneckenrührwerk operates by creating a continuous flow pattern within the vessel. As the screw rotates, it draws material from the bottom and pushes it upwards along its surface, while simultaneously moving material from the sides towards the center. This action ensures that all parts of the mixture are subjected to agitation, leading to uniform consistency and temperature distribution. Due to its design, it can handle a wide range of viscosities, from low to very high, and is often preferred for processes involving slurries, pastes, and doughs.
