Mikrofluidizáció

Mikrofluidizáció refers to the process of reducing particle size through high-pressure homogenization. In this method, a liquid containing suspended particles is pumped at very high pressures, typically between 1000 and 2000 bar. This high-pressure fluid is then forced through a narrow gap or valve, creating extreme shear forces, turbulence, and cavitation. These forces cause the particles to break down into smaller entities. Mikrofluidizáció is particularly effective for a wide range of materials, including emulsions, suspensions, and cell disruption. The precise control over pressure and flow rate allows for reproducible particle size reduction and the creation of very small and stable particles, often in the nanometer range. This technique finds applications in various industries such as pharmaceuticals, cosmetics, food processing, and biotechnology, where controlled particle size is crucial for product performance, bioavailability, and stability. The process is often carried out in a continuous flow manner, making it suitable for large-scale production. The equipment used typically consists of a high-pressure pump, an interaction chamber, and a cooling system to manage the heat generated during the process.
