40% of the energy demand in the beverage industry in Australia was in the form of hot
water between 60°C and 80°C. Considering the temperature and heat requirements of
food processing, one would be tempted to conclude that SIPH would be ideal. However,
many food processing requirements are seasonal, which may not be economical con-
sidering the present price of ...
