What role does the HTST pressure differential controller serve?

The HTST (High-Temperature Short-Time) pressure differential controller plays an essential role in ensuring proper flow through the pasteurization system, and its primary function is to control the booster pump. This is crucial because the booster pump needs to maintain a specific pressure to ensure that the fluid is moved efficiently through the heat exchanger and pasteurization equipment.

This controller monitors the pressure differential between the inlet and outlet sides of the pasteurization unit. By maintaining the correct pressure, it helps ensure that the pasteurization process occurs effectively and consistently. If the pressure differential falls outside of the acceptable range, it can indicate that there is an issue that needs to be addressed, which directly impacts the safety and quality of the pasteurized products.

While managing flow rate and temperatures are important in the pasteurization process, these functions are typically handled by other controls and components within the system. Therefore, the focus of the HTST pressure differential controller on regulating the booster pump is vital to the overall operation and success of the pasteurization process.
