Propeller Agitator

Propeller agitators are commonly made of three bladed attached to the main shaft. They are flexible in operations and mostly used in mechanical mixing of low to medium viscosity fluids. These type of propellers are also called as marine type propellers. The diameter of the propellers depends on the rotational speed and diameter of the batch reactor or the agitator vessel. Depending on the agitator vessel size and the fluid viscosity the power consumption of the propeller agitator may exceed more than 50kW.

Features of Propeller Agitator :

• The entire machine is operated automatically thereby reducing the need of frequent labor inspection.
• There is an automatic operation using differential pressure method to make the entire work easier and efficient.

Application : Dairy and food processing Chemicals processing

Advantages :

• Less Metzner ott shear rate constant
• Homogenization
• Good miscibility

Disadvantages :

• Motion of liquid starts on one spot
• Dead spots formation at high rotation speeds
• Occurrence of solids settling at low speeds
