What is the function of the deflector plate in the HTST regenerator?

The function of the deflector plate in the HTST (High Temperature Short Time) regenerator is primarily to change the direction of product flow. This is important within the context of a heat exchanger system, as the deflector plate aids in optimizing the flow of the product to ensure efficient heat transfer.

In an HTST system, the regeneration process uses heat from the outgoing product to preheat the incoming product, which helps minimize energy usage and enhance overall efficiency. By altering the flow direction, the deflector plate helps maximize contact between the product and the heat transfer surfaces, thus improving thermal exchange. This process also plays a role in ensuring that the product flows evenly across the heat exchange surface, facilitating uniform heating.

The other options do not accurately reflect the function of the deflector plate. For example, measuring pressure, increasing temperature, or filtering solids are roles associated with other components in the HTST system and do not pertain to the specific action of the deflector plate.
