how to control temperature in Direct steam injection

DSI (Direct Steam Injection) are most popular pasteurization system, it's because small and simple design and process.
to get pasteurization procces in milk powder, only need steam and teflon.
steam directly inject into liquid to get high temperature.
to control value of stean pressure we must instal regulator valve ind it's controlled by computer

as aregular process we must create mmi to comunicate sensor temperature with MMI
with PID system we wil get better automatic stem to control temperature output
