SUPERBLEND cleared an inconsistency between the laminar flow and turbulent flow using the 2-shaft mechanism.
Multipurpose mixer that exceeds the limitation of the vertical-type mixing vessel.

The homogeneous mixing from low viscosity to high viscosity, which was a critical issue of the mixing vessel, was attained by the 2-shaft mechanism with different impeller shapes. This mechanism always offers the optimum operations for an abrupt change of viscosity that is caused at multiproduct production or polymerization.



Vertical-type mixing vessel that has two coaxial mixing shafts equipped with the MAXBLEND impeller (inside) and helically-deformed baffle plate (outside).

Mixing mechanism

1. Combination of discharge and shearing functions
SUPERBLEND provides both the discharge and shearing functions by placing the mixing vessels that have different mixing characteristics for the inside and outside.
2. Following-type change of mixing function depending on a change of viscosity
The main function of the entire mixing is changed by an interaction depending on the viscosity environment, offering the appropriate mixing performance in a wide viscosity range.

Features of SUPERBLEND

1. Applicable area in wide viscosity range
Differences between turbulence flow and laminar flow, that was an issue in the previous models, have been cleared by different mixing characteristics of the inner and outer impellers.
SUPERBLEND offers continuously excellent mixing performance in a wide viscosity range of 1 to 10,000 poise or more.
2. Smooth support of abrupt change of viscosity
The mixing functions of the inner and outer impellers run flexibly to suit a change of viscosity in the vessel, thereby, ensuring the appropriate flowing following an abrupt change of viscosity during reaction.
3. High temperature uniformity
The stable flow speed is ensured on the wall surface and in the center of the vessel by the synergistic effect of the inner and outer impellers, offering the high uniformity in temperature. This feature significantly reduces a degradation of the polymer quality in the heat-spot.
4. Formation of powerful suction flow in gas-liquid interface
A low-viscosity fluid sliding or staying phenomenon on the high viscosity fluid interface, which is an issue in the DOUBLE HELICAL RIBBON baffle of the previous model, is resolved, thereby, realizing a significant enhancement of a dispersion of reflux fluid and polymerized addition agents.
5. Appropriate slurry suspension
Fouling or aggregates detected on the vessel wall or baffle plate during high-concentration of slurry operation, which are issues in the fixed-type baffle, have been resolved by using the mobile-type helical baffle.
6. Reduction of attachment amount in vessel
The stable wall-surface flow speed is ensured by the outer impeller that rotates adjacently the inner wall of the vessel, thereby, reducing fouling on the inner wall and significantly decreasing the inside washing time and count.

Use applications

  2. 2. Polycondensation reaction
  3. 3. Monomer removal and desolventizing operations
  4. 4. High-concentration of slurry and high-concentration of crystallization operations
  5. 5. Powder and resin dissolution operations
