What is the Twin Jet Nozzle?

Conventionally, the only way to produce fine particles 10 μm or smaller was to either suppress throughput or lower solid content concentration. The twin jet nozzle we developed enables the mass production of fine particles without applying such restrictions.

List of Functions

1. Reduces atomization air volume by using collisions to atomize.
2. It is easy to scale up from the low throughput RJ nozzle to the high throughput TJ nozzle.
3. Atomization capacity to support stock solution throughputs of from several L/h to 1,000 L/h.

Atomizing method (nozzle)



1. As a first step, liquid is sheared with air to produce gas-liquid jet flows.
2. As a second step, the jet flows sprayed in the first step are made to converge at a single point to thus promote atomization by causing the jet flows to collide with one another.
3. Enables large throughput without hindering atomization performance by giving the slits a donut shape (TJ nozzle)
