Direct Steam Injector (DSI)
Direct Steam Injector (DSI) Direct Steam Injector (DSI) system, commonly used in sterilization processes for liquids. This system heats and sterilizes a liquid medium by directly injecting steam into it, ensuring rapid and efficient heating. Let me explain the process in detail, based on the components in the diagram: 1. Unsterile Medium In The process begins with the unsterile liquid medium entering the system. This medium will undergo heating and sterilization in subsequent stages. 2. Pre-heat Heat Exchanger The unsterile liquid first passes through the pre-heat heat exchanger . This heat exchanger uses residual heat (usually from the sterilized medium or cooling water) to preheat the liquid before the main heating phase. Preheating improves energy efficiency and prepares the liquid for sterilization. 3. Venturi Valve and Steam Injection After preheating, the liquid passes through a Venturi valve , where steam is directly injected into the medium. The Venturi effect creates a p...
