<p>PROBLEM TO BE SOLVED: To provide a sanitary and compact device for manufacturing composting material which treats material to be treated discharged from a home, an eating house, a school or the like by blending and agitating with biological bacteria being decomposing microorganism to obtain composting raw materials of semiproduct in a short time and to improve deposition treatment efficiency. SOLUTION: Rotary blades 9, 10 are disposed at a bottom part 12 of a charging brewing tank 2 and further a spiral-shaped blade 11 which has a band-shaped material shape and is wound to a spiral shape so as to envelop both rotary blades 9, 10 is provided in the charging brewing tank 2 so as to rotate around a shaft line P being in parallel to shaft lines of driving rotary shafts 5, 6. The spiral-shaped blade 11 rotating between the bottom part 12 of the charging brewing tank 2 and the rotary blades 9, 10 is rotated between the charging brewing tank bottom part 12 to scrape up and blend the material to be treated.</p> |
