Abstract

Mixing is one of the most primary operations in industries like chemical, Biochemical, food, cosmetic, and pharmaceutical applications. Though the customer have standard sized agitator with standard parameters but this method is time consuming as well as it consumes the more power for a batch type process. In this work the power requirement for small size agitator to mix two fluids are analysed with optimum time. This paper describes the mechanical design of agitator to mix polyelectrolyte having viscosity1.5cp considering the fluid forces that are imposed on the impeller by the fluid. Agitator design is often though as the application of two engineering disciplines. The first step is process design from a chemical viewpoint and involves the specification of the impeller pattern, speed, temperature and blade angle etc. The next step in the design sequence is the mechanical design of the agitator component. The approach is straight forward design for the power (torque & speed) then shaft loads. The experiment is carried out for agitator 500 litres of capacity. Drawback of the old agitator is removed. The old agitator does not gives homogeneous mixing.
