Advantages of Maxblend
Quickly achieves complete homogenization
The innovative flow pattern enables faster uniform mixing compared to conventional impellers.
Handles a broad viscosity range
Unlike conventional impeller agitator, Maxblend maintains stable mixing performance across a broad range of viscosities, making it ideal for processes with fluctuating liquid levels and multi-product operations.
Superior heat transfer efficiency
Maxblend creates a strong, uniform flow along the entire vessel wall, resulting in higher heat transfer coefficients. Combined with its exceptional mixing capability, it ensures uniform temperature distribution throughout the vessel.
Furthermore, unlike multi-stage impellers, it exhibits minimal variation in heat transfer performance when liquid levels change, making temperature control at ease.
Stable performance with liquid level variations
Conventional multi-stage impellers suffer from circulation flow instability when liquid level changes. Maxblend ’s continuous vertical blade profile maintains stable mixing performance regardless of liquid volume.
(This is realized because the circulation flow discharge is not located at the vesseel bottom, preventing flow pattern disruption when the liquid level changes.)
Uniform solid dispersion
A strong discharge flow from the vessel bottom results in a uniform dispersion of solids at lower rotation and power. Additionally, there are no local high shear areas near the blades as seen in conventional agitator blade, minimizing the physical breakage of solid particles.
The graph compares the degree of crystal fragmentation after 18 hours of continuous agitation, per type of blades, in which crystal particles sized from 590 to 1000 μm uniformly dispersed.
Easy particle size control
Unlike conventional impeller agitator, Maxblend provides a uniform shear field throughout the entire vessel, maintaining particle size distribution in a narrow band during suspension polymerization and crystallization processes. Also, particle size can be precisely controlled simply by adjusting the rotation speed.

Reactor
Standard agitator type Reactor (Impeller, anchor and turbine agitator)
In addition to advanced blade designs, we also supply a wide range of proven, conventional agitator blades. Our team can recommend the optimal blade selection to match your specific process requirements.
Flow patterns
Impeller blade (Three-blade backward-curved)
Draws fluid along the shaft axis and discharges from the blade tips, generating an upward circulation loop.
Anchor blade
Draws fluid from center and discharges from the agitator shaft end, creating upward and downward convection zones bordered by the midsection of the vertical blades.
Turbine blade
Draws fluid from middle of upper and lower blades and discharges from the blade tips, generating upper and lower circulation loops.
