TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The evaporation gas produced during the drying process is condensed and the organic acid contained in the evaporation gas is condensed and recovered as condensed water. The aqueous solution containing organic acid, condensed water containing organic acid and a quality management material, are mixed. The foodstuffs scum processed material obtained after drying process is pelletized (S3) and utilized as fodder or a fertilizer.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Material: The quality management material contains at least one type of mineral component chosen from calcium, magnesium, iron, manganese, zinc, copper and molybdenum. EXAMPLE - Tofu lees (50%), restaurant cooking scums (30), bread waste (5%), rye rice-bran (5%) and mixed feed (10%), were mixed and used as raw material for foodstuffs scum. The moisture content of the raw material scum was 65%. The raw material (60 kg) was added to a fermentation tank. Lactobacillus and fermentation promotion liquid consisting of culture solution of yeast (6 l), were added and stirred at 40degreesC for 24 hours. The resulting mixture was fermented and the moisture content in the scum after fermentation was 60%. The scum was dried at 80degreesC for 12 hours until the moisture content was reduced to 30%. The dried scum was extruded, molded as pellet with a diameter of 5 mm and average length of 7 mm and pellet (30 kg) was obtained. The obtained pellet contained nutrient component comprising 27.9% of crude protein, 15.9% of crude fat, saccharide, starch, 15.6% of organic acids, 36.4% of total fiber and 6.1% of crude ash. The pellet containing effective nutrient powder was used as fodder. The odor gas generated during fermentation process was contacted with alkali aqueous solution containing calcium with pH of 12 and the neutralization liquid was recovered. The odor in the gas exhausted after neutralization recovery, was removed. The evaporation gas with a temperature of 80degreesC produced during drying process was cooled to 10degreesC and recovered as condensed water. Shellfish-shell was added as calcium mineral component to the recovered water and a mineral liquid was manufactured. The mineral liquid had pH of 4.5 and electroconductivity of 20 mS/cm.
