An energy accounting study was conducted to find possible energy recovery in the production of foods such as bread, spaghetti and rice cracker (senbei).<br>The energy accounting was restricted to in-plant energy use. Those foods are merle of grain flour and needed thermal operations to be processed. Senbei is one of Japanese traditional and popular cookies made of rice flour.<br>The energy requirement in the production of bread, spaghetti and senbei was 2.06, 3.33 and 11.43MJ/kg product respectively. Baking used about 40% of the total energy in bread production, and drying in the production of spaghetti and senbei consumed 65.2% and more than half of the total energy respectively.<br>These energy intensive operations in each of the food productions also rejected a large amount of the thermal energy from an oven and a dryer with exhausted air. Thus, the exhausted air could be a source of the energy recovery and be used for an absorption refrigeration system for a bread cooler which will replace the current refrigeration unit. This problem was left for a future study.
