Paddle agitators consist of two flat paddle-shaped impeller blades extending to reach the tank walls. They are used if no extensive axial and radial flow is required. These impellers can produce a laminar low shear flow and are used for low viscosity liquid mixing, crystallization, dissolution, and heat transfer. They are typically operated at low speeds and predominantly give a tangential flow pattern. Secondary blades can be installed on the paddle blades to enhance the mixing of more viscous materials.The impeller blades are inclined from the plane of rotation to create an axial flow pattern. This variation of paddle agitator is typically used for homogenizing suspensions.
Paddle Agitator Mixers generally used for large scale equipment, such as polymerization tank, PVC reactor, saccharifying tank, gelatinization reactor etc. The stirring device is installed at the bottom of cylinder or tank equipment , the mixer shaft is shortened and there is no coupling between mixer shaft and transmission shafts, which improve the stability of shaft. At the same time, the stress state of head of the tank is improved, and the installation requirements are also reduced. Paddle Agitator Mixer is also beneficial for mixing of materials in the bottom, which can get full mixing of all material.Paddle Agitator Mixers are good choices for outputs from bottom of tank , which can make the discharge port mixing well.  Bottom entry agitator are designed to fit into the bottom or side of a mixing vessel. These high shear Paddle Agitator Mixers are typically used in conjunction with a slow speed anchor stirrer or scraper unit for high viscosity products.
KEANs KCXZ series of Paddle Agitator Mixers are designed to fit into the bottom or side of a mixing vessel. These high shear mixers are typically used in conjunction with a slow speed anchor stirrer or scraper unit for high viscosity products. The KCXZ Paddle Bottom Entry mixer gives high shear homogenization while the stirrer/scraper distributes the homogenized output uniformly through the vessel. Paddle Agitator Mixer is ideal for high viscosity cosmetic, pharmaceutical and food products.
 
Typical Applications:
Storage tank mixing
Fermentation and Bioreactors
Low shear blending
Food and beverage
High Shear bottom entry mixing
 
Using high speed to mix liquids, it is suitable for mixing device of liquid reaction tank in sterile preparation, food and beverage, chemical, biological engineering and other industries which are not sensitive to shear force.
