Mixing plays a crucial role in many chemical processes, from the production of pharmaceuticals to everyday consumer goods. Effective mixing ensures that two or more streams combine into a homogeneous solution with minimal local variations in concentration and temperature. In fast chemical processes, rapid mixing is critical to ensure they unfold in a homogeneous environment, which is key for achieving consistent product properties and ensuring safe, controllable, and efficient operation.
Impinging jet mixers (IJMs) have been an important technology for achieving rapid mixing for many years. Developed over 70 years ago, these devices work by directing two high-velocity fluid jets toward each other, often reaching speeds of up to 100 m/sec. When the fluids collide, the impact creates a high-energy zone where the solution is fully mixed in milliseconds — which is many times faster than traditional mixing equipment like stirred tank reactors. IJMs are inherently scalable, with higher volumetric throughput often enhancing performance — up to a point — making them ideal for processing volumes of several liters per minute without sacrificing mixing effectiveness.
