Context & Assumptions

The Flow Diversion Valve (FDV) setpoint calculation is a critical safety function in High-Temperature Short-Time (HTST) pasteurization systems. It ensures that product is diverted back to the balance tank if the temperature falls below the regulatory threshold, preventing under-processed product from proceeding. Incorporating a safety tolerance and hysteresis offset prevents rapid valve cycling and maintains food safety compliance.
