Which of the following is NOT true with respect to size reduction?
(a) Size reduction is an energy inefficient process as the energy required for grinding is very high
(b) Some of the energy liberated in the formation of new small surfaces is the grinding energy required by food material per unit surface area to form new surface areas and the rest is generally just heat
(c) The crushing efficiency is inversely proportional to the surface created
(d) None of the mentioned
This question was posed to me in an interview for internship.
My query is from Unit Operations in portion Sedimentation and Centrifuge, Mixing, Size Reduction and Separation and Material Handling and Transportation of Food Engineering
