Energy Recycling in the Bread Baking Process (II)

Abstract

Heat balance of a spiral oven was measured and compared to that of the tray oven previously measured. Heat efficiency of the spiral oven was higher than that of the tray oven. Hence exhausted energy of the spiral oven was lower. Suppose the reuse of exhaust gas, the recovery of exhausted energy of the spiral oven is easier. The bread cooler for energy recycling was investigated. A part of the cooling room was cooled by ambient air, so cooling of bread depended on weather. Energy recycling system was proposed by using energy accounting diagram of oven and bread cooler.
