Individual Revolution and Rotation
Speed Control System
The speed of rotation and the speed of revolution are independent with “Kakuhunter”.
The ratio of revolution to rotation can be changed with up to 90 rotational patterns.
Issues with General Planetary Centrifugal Mixers
-
Insufficient Mixing and Defoaming
As the ratio of rotation is fixed,
mixing fails or lumps tend
to easily form even if the
speed of revolution is adjusted. -
Temperatures Rises of Materials by Frictional Heat
The temperatures of materials
rise due to frictional heat of
mixing. -
Precipitation of Materials with Insufficient Viscosity
With materials having different
specific gravities, viscosity
decreases and materials
higher in specific gravity
are precipitated.
Kakuhunter Helps Solve These Challenges !!

Optimal processing conditions in mixing and deaeration applications depend on numerous material characteristics, including viscosity, specific gravity, particle size, formulation ratio, and batch size.
While some materials require intensive shear for effective dispersion, others demand gentle processing to prevent particle damage and excessive temperature rise. As a result, precise control of revolution and rotation speeds is critical for achieving consistent product quality.
Kakuhunter's Separate Control System independently controls revolution and rotation, providing exceptional flexibility throughout the entire process—from initial blending and powder incorporation to agglomerate breakdown, homogenization, particle refinement, and deaeration.
The system also enables process-specific optimization, such as minimizing material stress with high-revolution/low-rotation operation or generating strong shear forces with high-rotation settings.
By allowing independent adjustment of revolution and rotation speeds, Kakuhunter enables material-specific process optimization that is difficult to achieve with conventional systems employing a fixed rotation ratio.
Optimal revolution and rotation settings depend on material volume and viscosity. Excessive rotational force may negatively affect product quality.
With an adjustable rotation-to-revolution ratio, Kakuhunter offers up to 90 setting combinations, allowing users to identify
the optimal mixing conditions for a wide range of materials.
Rotation can be Changed Independently, Having Such Advantages as:
-
Advantage01
Minimizing Mixing Non-Uniformity in High-Viscosity Materials
High-viscosity materials and formulations containing a high proportion of powders often
exhibit limited flowability, making them prone to unmixed zones and particle agglomeration.
By optimizing the rotation speed, Kakuhunter efficiently applies shear force throughout the material,
improving mixing uniformity and facilitating a more homogeneous processing state. -
Advantage02
Minimizing Temperature Rise and Material Damage
Excessive shear forces may cause heat buildup, particle fracture, and degradation of
resins or functional additives, potentially compromising material properties and product performance.
By optimizing the rotation-to-revolution ratio based on specific process requirements,
Kakuhunter delivers the required mixing performance while reducing unnecessary mechanical stress on the material. -
Advantage03
Enhanced Powder Incorporation and Dispersion Efficiency
Following powder addition, materials often float on the liquid surface or form powder agglomerates,
which can delay homogenization and lead to incomplete dispersion.
Kakuhunter utilizes convective flow generated by revolution together with flow control induced by
rotation to efficiently incorporate powders into the liquid phase, improving dispersion efficiency and process consistency. -
Advantage04
Optimizing the Balance Between Dispersion and Deaeration
Aggressive mixing conditions can promote air entrapment, while processing conditions focused
primarily on deaeration may compromise dispersion performance.
With independent control of rotation and revolution, Kakuhunter allows users to optimize the balance
between dispersion and deaeration according to material properties and process objectives, helping to
achieve superior processing results. -
Advantage05
Tailored Process Conditions for Different Materials
The optimal flow characteristics required for processing vary considerably among low-viscosity liquids,
high-viscosity pastes, and powder-containing formulations.
With an adjustable rotation-to-revolution ratio, Kakuhunter enables precise selection of process parameters
tailored to specific material properties and application requirements, helping users achieve optimal processing performance. -
Advantage06
Reduced Processing Time Through Process Consolidation
Processes such as mixing, powder incorporation, homogenization, and deaeration can be carried out
continuously by optimizing processing parameters at each stage.
By minimizing material transfer, handling, and equipment reset between process steps,
Kakuhunter contributes to shorter processing times, improved operational efficiency, and more consistent product quality.
The Power of the Individual Speed Control System is This Much!Combined Usage With the Special Function “Step Operation”
- * Step operation…
Continuous running of multiple different operation patterns can be performed by this function.Details.
We want to defoam without using vacuum equipment from the aspect of material characteristics
Defoaming is performed by the powerful centrifugal force of revolution in a short time.
Application example
Defoaming of silicone resin (example of defoaming with the SK-350TII)


Want to Prevent Materials from Changing Due to Temperature Rises
Temperature rises are suppressed
by the Individual Revolution and Rotation Speed Control system
For mixing high-viscosity materials, the speed of revolution needs to be increased, where the temperatures of materials rise sharply due to the friction with containers.
Care must be taken since some materials change with temperature rises, but the individual revolution and rotation speed setting function enables mixing and defoaming while suppressing such temperature rises.
Want to Resolve the Issue of Lumps in Materials during Mixing
The mixing ability is enhanced and the issue of lumps is resolved by the Individual Revolution and Rotation Speed Control system and step operation.
In mixing powder and resin, the powder tends to form lumps, making it difficult to crush.
By using the individual revolution and rotation speed setting function and step operation, mixing and defoaming can be performed while preventing lumps.
Application example
Pasting of alumina and silicone resin (example of mixing with the SK-350TII)


Want to Mix and Disperse Materials with Different Specific Gravities
The mixing ability is enhanced by the Individual Revolution and Rotation Speed Control system and step operation!
Additionally, even microfine bubbles are removed by the vacuum reduced pressure function.
Defoaming can be performed after controlling precipitation by reducing the speed of revolution while keeping the speed of rotation required for mixing and dispersing by the individual revolution and rotation speed setting function and step mode.
Additionally, the defoaming effect is enhanced by vacuum reduced pressure.
Application example
Mixing and dispersing of fluorescent powder and silicone resin with different specific gravities(example of mixing with SK-300TVS-A)
