| dc.description.abstract | Milk processing plants utilise both fossil fuel energy
and electrical energy. In recent years, there has been
considerable interest in efficient utilisation of energy
in these plants. The reasons for this include the need
to reduce energy cost in individual plants, the energy
import bill for energy importing countries, the rate of
depletion of non-renewable energy resources and the
adverse environmental impact associated with energy
use.
The following processes are important in milk
powder plants: steam generation, steam distribution,
condensate recovery, refrigeration, milk pasteurising,
milk evaporation, milk drying and cleaning. Of these
processes, only evaporation and drying are not found
in fluid milk plants. In this paper, ways of saving
energy in each of the above processes are discussed. | en |
