A revolution in mixing reaction systems.
The Taylor Vortex Flow NanoReactor, which achieves both narrow gap and high-speed rotation, enables nanoparticle synthesis with sharp particle size distribution and high sphericity through continuous flow synthesis under constant high shear force.
◆TVF Features tipton-us.com/...
Ultra-high precision = Ultra-high shear force enables generation of nano-particles.
The ultra-precise rotation mechanism with minimal runout enables both high-speed rotation and narrow gap.
This enables stable generation of particles of 100 nanometers or less.
Compatible with all kinds of chemical reactions and syntheses.
It can be used for acid-base reactions using strong acids and alkalis, and poor solvent crystallization reactions using solvents.
What is ◆Taylor vortex flow?
When a fixed cylindrical outer cylinder and a rotating inner cylinder are arranged concentrically with a uniform gap in between them; an annular vortex flow will occur when the inner cylinder is rotating at high speeds while the annular gap is being continually filled with fluid. A series of independent vortex rings that are generated in the enclosed space is called the Taylor vortex flow.
◆Features of Taylor vortex
(1) Significant improvement in production efficiency through continuous production.
Compared to conventional batch type equipment, the mixing and reaction process can be completed in 1/10 to 1/100 of the time. Also, no setup time is required due to continuous injection and discharge. Therefore, even if the production scale is the same as the batch type, the equipment used can be much smaller.
(2) High extrudability = Low dispersion
There is no irregularity in mixing and reaction time.
The bulk (non-reactant) that flows into the equipment hardly moves from vortex to vortex and remains in one vortex while constantly flowing out of the equipment in that single vortex state.
In other words, the time spent in the device is almost constant no matter where it is taken, so there is no unevenness in mixing and reaction time, which allows the treated material to have a narrow distribution.
(3) Sharp particle size distribution of the product is realized because the shear force is constant throughout the closed space.
The shear force acting on the fluid is proportional to the velocity gradient (the difference in velocity between the front and back, left and right).
Since the velocity gradient in a Taylor vortex is nearly uniform throughout, the contents are constantly exposed to a constant shear force. As a result, crystallization and emulsion particle size can have a very narrow distribution.
In addition, the shear force can be adjusted by the gap width between the inner and outer cylinder.
(4) Simple structure = Easy cleaning and setup.
The simple structure with a small number of parts allows for easy disassembly and cleaning.
Automatic in-line cleaning using hot water or strong alkali is also possible.
⑤High temperature controllability.
The temperature can be uniformly controlled over the entire surface of the outer cylinder, making it less susceptible to internal and external disturbances such as inflow temperature, heat from chemical reactions, and shear heat.
The inside of the reaction tank is always kept at a constant temperature.
(6) Ease of scale-up.
Scale-up is easy because the vortex flow state inside the system is determined by the Reynolds number.
