Question:
In HTST pasteurizer, raw milk enters and leaves the regenerator at the temperatures 4°C and 65.2°C respectively. If the pasteurization temperature is 72°C, then the regeneration efficiency will be:
In HTST pasteurizer, raw milk enters and leaves the regenerator at the temperatures 4°C and 65.2°C respectively. If the pasteurization temperature is 72°C, then the regeneration efficiency will be:
Show Hint

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Regeneration efficiency measures heat recovery.
It is calculated from temperature differences.
Step 2: Key Formula or Approach:
Regeneration efficiency = (T_out - T_in) (T_pasteurization - T_in) \(\times\) 100.
Step 3: Detailed Explanation:
T_in = 4°C, T_out = 65.2°C, T_pasteurization = 72°C.
Efficiency = (65.2 - 4) (72 - 4) \(\times\) 100 = (61.2 68) \(\times\) 100 = 90%.
Thus, the regeneration efficiency is 90%.
Step 4: Final Answer:
The regeneration efficiency is 90%.
Hence, the correct option is (C).
