This question was posed to me in examination.

My enquiry is from Unit Operations in chapter Heat Transfer Equipment, Microwave Heating, Evaporation, Diffusion and Mass Transfer and Dehydration of Food Engineering

Answer 1

Correct choice is (d) All of the mentioned

For explanation I would say: The overall pressure and temperature of steam increases which is desired and the capacity of the evaporator increases but there might be wear and tear in the evaporator.
