Notes:
Consumption of direct energy sources in a plant producing spray-dried coffee amounted to 12,930 kcal/kg of instant coffee (kg IC). Thermal energy sources accounted for 95% of the energy and electricity for the rest. Spray-drying was the most energy intensive operation, requiring 5,040 k/kg IC. Thermal energy consumption (kcal/kg IC) for roasting, extraction, and concentration was 890, 2,030, and 1,780, respectively. Thermal energy losses in the unit operations amounted to 55% of that consumed. Heat recovery and insulation techniques can be used to conserve about 70% of the losses.
