Question

Calculate the regeneration efficiency if the milk is heated from an initial temperature of 4\(^\circ\)C to 67\(^\circ\)C in a regenerator and pasteurization was done at 74\(^\circ\)C.

• A. 80%
• B. 75%
• C. 90%
• D. 85%

Hint:

To quickly find regeneration efficiency, use the ratio of the achieved temperature rise to the total required temperature rise:
\[ \frac{\text{achieved rise}}{\text{total rise}} = \frac{63}{70} = \frac{9}{10} = 90\% \]

Answer 1

The Correct Option is C
