In organic waste treatment, initial investment andrunning costs are suppressed, and inexpensive and good-qualitydried and fermented feeds and fertilizers are manufactured fromanimal and plant residues. The animal and plant residues havingbeen reserved / accumulated in a fermentation tank and generatedfermentation heat is emitted / sprayed with air into a spacein the fermentation tank and repeatedly circulated within theapparatus so that an evapotranspiration action is efficientlyperformed, oxygen required for fermentation is uniformlysupplied so as to keep a favorable fermentation environment,and an apparatus for producing good-quality dried and fermentedfeeds and fertilizers is provided.
