Different Viscosity and Thickness Liquid Mixing

Thanks to the experience we have accumulated over the years and based on our expertise, we are able to assist in choosing the right mixers and thereafter design appropriate mixing units for particular liquid-liquid systems. Depending on the viscosity and thickness of the liquids involved, we offer a diverse range of agitator types that may be used. Additional factors which should be taken into account include:

• the weight ratio of the liquids involved
• their mutual solubility
• the temperature and pressure of the process
• whether aeration of the substance is allowed
• hygiene and sterility requirements
• process yield
• sensitivity of the substance to the shear forces generated by the agitators
• an analysis of potential risks in the case of hazardous substances
• the possibility to clean the device

Having analyzed the above issues, we select a type of agitator or an agitator pack, calculate the required power supply and decide on the positioning of the agitator in the substance processed.
Thereafter, the whole system is analyzed with respect to the process it is to carry out, i.e.:

• the possibility of an occurrence of vibrations
• the performance of the agitator depending on the level of the liquid.
• the interaction of a number of agitators within a single mixer
• other aspects resulting from the planned configuration of the mixer.

Kates produces agitators capable of mixing several liquids at the same time, including mutually insoluble liquids – for those we apply agitators generating high shear forces, such as homogenizing agitators, turbine agitators, etc.

Each agitator is put to a test and the company laboratory examines various designs on an ongoing basis.

Examples of agitators in action:

• a propeller agitator with variable rotational speed

• a paddle agitator in action,

• a paddle agitator and a homogenizing agitator in action at the same time, without an external cycle.

The number of possible agitators and the variety of tank designs yields an enormous range of mixer variants.
