Satake thinks about mixing mainly in terms of the flow.
It is of course important to think about the process as well. To realize the required mixing action, we think about necessary performance of fluid machinery by simplifying it based on the aspect of flow. However, we arrange the process systematically instead of merely making it more complicated.
When viewed in this light, the impellers can be named the "life" for achieving the segmented objectives of mixing in every field of application. For general types of impeller, a three-bladed propeller, four pitched paddle, six flat (pitched) turbine etc. are used in the range of high Reynolds number of mixing while an anchor blade, helical ribbon blade, etc. are used in the low range of Reynolds number. However, they are not perfect in achieving the mixing objectives that have arisen in recent years that have become ever more diverse and complex. Given this factor, we continue to strive to meet your needs to the best of our abilities. We promote R&D on the development of high-performance impellers based on the aerofoil theory to satisfy mixing objectives. At the same time, we constantly review more accurate operating conditions.
We have called these newly developed impellers "The Super-Mix Series". A display of the Series will be introduced to you here.

For application in the high and medium ranges of Reynolds number

High-discharge and high-efficiency axial-flow impellers
Registered design
Super-Mix HR100
This is an energy-saving low-shearing type impeller boasting a high discharge performance. It was completed after reviewing the planar shape of the blade, angle of attack and camber ratio. This impeller suppresses the flow separation on the back of the blades by introducing a multi-stage folded-back structure.
Patent Pending,Registered design
Super-Mix HR700
The blade exhibits a wash-out circular design and adopts an appropriate forward swept wing shape. The planar shape of the blade, the angle of attack and camber ratio are important elements on which blade performance depends. HR700 is an impeller with superb discharge performance.
Super-Mix HV200
It has double-blade developed by Satake and based on our research on the three-wide blades and auxiliary blades. By eliminating and rectifying the flow separation generated on the back of the main blade with the slot effect of the slotted flaps, we have succeeded in sharply increasing discharge capacity and maximum rate of discharge.
Patent Pending
Super-Mix HR320
We have adopted the forward swept effect into the blade. In addition, the blade has a single-step bent-up structure with wash-out being provided toward the blade tip. This impeller is for a low-speed mixer with improved discharge performance through a suppression of flow separation on the back of the blade.
Super-Mix HR320S
Double-blade construction is adopted based on HR320. This impeller is provided with anti-vibration measures using a unique blade tip plate in consideration of vibration generated by agitation in the vicinity of the tank bottom and by the blade passing through the liquid level.
Patent Pending
Super-Mix HR800 (New!)
The main blade has a tapered shape with an incline for suppressing the flow separation. A double-blade structure has been adopted to reinforce discharge from the center of the impeller. This impeller efficiently suspends and fluidizes slurry with low motive energy consumption.
High-dispersion bottom impeller
Patent Pending,Registered design
Super-Mix HS600
HS600 Series impeller has been researched and developed not as a single blade unit but as mixing equipment included in the mixing tank. It has improved the mixing action in the "uniform dispersion series" including solid-liquid and slurry agitation by controlling the pressure distribution inside the tank.
High-shearing radial flow turbine
Super-Mix HS100
We have realized a very low power number for a turbine.(Power number compared with 6FT: Reduction of approximately 65%) Compared with the conventional turbine type, it offers higher liquid fluidizing action and gas absorption capability. It concentrates the flow by using the lifting force of the impeller with low power, and produces strong shearing and destructive actions utilizing pressure gradient and fluctuation in the discharge field.
High-efficiency surface aeration impeller
Patent Pending
Super-Mix SA200
A surface aeration impeller adopting a swept back tapered blade shape. A distribution form (umbrella) created by the upper disc and used for spraying thin films of liquid promotes improved suction (lifting) efficiency on the liquid surface and efficiency of gas absorption.

For application in the high, medium and low ranges of Reynolds number

Special large impeller
Registered design
Super-Mix MR203
MR203 is a special large- and broad-bladed impeller developed mainly for application in the medium to low ranges of Reynolds number with high mixing performance. Satake's proprietary special serrated shape used in this impeller, and the trapezoidal shape running toward the bottom of the tank produce strong suction flow and major circulating flow due to the clearance effect at the center of the shaft. This impeller is particularly suitable when the attachment of content to the blade needs to be avoided, or when washing properties are important.
Patent Pending,Registered design
Super-Mix MR205
This is a large- and broad-bladed impeller that exhibits a double-blade effect. The pressure difference between the front surface of the main blade and the auxiliary blade surface provides powerful discharge flow in a radial direction even in highly viscous liquids. Furthermore, the large trapezoidal blade radius toward the bottom of the main blade creates a strong upward flow from the tank bottom to the liquid surface. In addition, the serrated shape of the slit to the main blade has realized uniform mixing by completely eliminating mixing failure.
Patent Pending
Super-Mix MR210
MR210 impeller is a high-efficiency mixer contributing to the improvement of both the mixing performance and a reduction of power consumption. To achieve effective liquid fluidization and mixing action with a simple construction and smaller blade area, the suction flow from the liquid surface was reinforced by using the clearance effect of the main blade and the shaft. In addition, consideration was given to the blade area in the vertical direction to improve the pressure distribution within the tank.
Patent Pending
Super-Mix MR524
This is a layered impeller with no central axis. It has succeeded in drastically improving the mixing performance in the ultra high viscosity range (mixing Reynolds number of 1 or less) where mixing was conventionally difficult to implement in the mixing tank. Multiple stages of the blades in a tilted arrangement generate strong upward and downward currents. The bottom blades were provided to reinforce the mixing process in the bottom of the tank. The tilted blades have contributed to realizing high mixing performance.

Super-Mix examples of application by objectives

Application of Super-Mix HS600 Series for uniform distribution

Reproduce the movie
For the purpose of evaluating distribution performance, we introduce here the comparative test results with the conventional type paddle impeller using the glass beads as the index for the distributed state. (Under the condition of power Pv per unit capacity being constant.) Judging from the flow conditions and bead deposits on the tank bottom, the test example shows that HS600 has provided favorable distribution patterns by effectively using the tank bottom surface.
A powerful discharge from the tank bottom forms a loop of major circulating flow that reaches every area in the tank. Such a flow pattern is optimum for achieving uniform distribution within the tank.
This example shows the concentration analysis of solid substances in the solid-liquid uniform distribution system of pseudo-catalyst and water. Compared with the conventional type paddle blade (4PP), HS600 exhibits very high performance of uniform intra-tank distribution with drastically minor dispersion (´ŻąC) from the charged concentration (C0).

Application of Super-Mix HS100 Series for gas-liquid distribution

Reproduce the movie
The state of gas distribution at the time of aero-agitation was compared with that of the conventional 6-blade flat turbine (6FT). 6FT tends to hold the gas on the back of the blade, degrading the shearing and liquid-fluidizing action. Conversely, HS100 concentrates the flow with the lifting power of the blade, not with the negative pressured portion, and offers a shearing action and liquid-fluidizing pattern by utilizing the relative rate difference (pressure fluctuation) in the discharge tank. This helps prevent degradation of performance during aeration as is the case of a 6FT.As the movie shows, HS100 distributes bubbles down to the bottom of the tank and that highlights the small size of the bubbles.
The vector length in the diagram represents the speed. Compared with 6FT, HS100 has greater flow rate in the vicinity of the tank bottom, indicating its high liquid-fluidizing performance in the tank.
This is a relational diagram between consumption power (Pv) per unit capacity for aero-agitation and the gas absorption capacity KLa. HS100 proves that it is a high-performance turbine to acquire high gas absorption performance using comparatively smaller power than 6FT.

Application of Super-Mix MR205 for high-viscosity liquid agitation (in low range of Reynolds number)

Mixing performance of MR205 is indicated in the agitation of high-viscosity liquid (starch syrup solution) using iodine-hypo decolorization. For sake of comparison, a helical ribbon impeller is used under the agitation test condition of Re = 100 constant. With the helical ribbon impeller, the mixing process begins near the blade. The mixing in the vicinity of the axial center forms the rate-controlling factor.It takes a long time before the faulty mixing portion is eliminated. With MR205, mixing proceeds uniformly in all areas of the tank immediately after starting agitation. The diagram shows that the mixing time is very short and that no faulty mixing portion exists that could cause problems in the low Reynolds area.

Application of Super-Mix SA200 for surface aero-agitation

This shows the state of liquid surface during aeration. Since 4PP adopts a distribution pattern with the hammering of the liquid surface, the pattern is irregular and instable without forming the umbrella. On the other hand, differing from 4PP, SA200 is seen forming the umbrella in thin film that contributes to improving the gas absorption rate.
As backed up by the relational diagram between consumption power (Pv) per unit capacity and the gas absorption capacity KLa, it shows that SA200 Series has very high gas absorption performance.

New Super-Mix technology - RB Mixing System

Tornados are created inside the tank. The impeller creates the swirl flow. The center-oriented flow on the bottom of the tank is efficiently converted into a tornado-like upward flow with the "RadialBlade = R.B."
Reproduce the movie
Since the main flow is the swirl flow rotating in an identical direction to the impeller, it enables the creation of agitation with extremely small shearing force. This can be optimally applied to agitation where the shearing force needs to be minimized such as in the biological, chemical and water treatment areas.
This shows an application example from the reaction tank in an actual wastewater treatment process. High-distribution characteristic attributable to low shearing is fully exploited to provide superb performance during the actual process.
