What is the effect of bypassing the HTST raw regenerator section in diverted flow?

Bypassing the High-Temperature Short-Time (HTST) raw regenerator section in a diverted flow scenario is primarily beneficial for the startup of the HTST system. This action allows the system to initially operate without the full thermal exchange that occurs when the regenerator is functioning. During startup, it can be advantageous to bypass this section to facilitate the rapid raising of temperature of the product and ensure that the system reaches operational conditions efficiently.

This approach helps in stabilizing the total system while ensuring that the pasteurization process can commence without delay. Once the system is operating optimally, the regenerator can be reintroduced to maximize energy efficiency and achieve the desired pasteurization standards. Thus, this option highlights an important operational strategy in managing the HTST equipment effectively during startup phases.
