<p><P>PROBLEM TO BE SOLVED: To provide a garbage disposal apparatus, a feed fermentation apparatus, and a compost fermentation apparatus capable of carrying out the treatment in a short period of time at a relatively high temperature making use of aerobic bacteria and a plurality of light and inexpensive agitation impellers that can minutely pulverize an object to be fermented, can sufficiently supply oxygen to the object, and can achieve sufficient fermentation at a relatively high temperature. <P>SOLUTION: The agitation impellers for use in the garbage disposal apparatus, the feed fermentation apparatus, and the compost fermentation apparatus are helically disposed on a rotary shaft, which are deviated from each other by a predetermined deviation angle with respect to the rotation direction thereof, thereby effectively agitating an object to be fermented. Further, each of the agitation impellers is securely fixed onto the rotary shaft by virtue of a whirl-stop welded to the rotary shaft on a position whereon a predetermined gap formed between fixed flat end parts of a pair of impeller fixing pedestals is located, thereby effectively agitating the object to be fermented. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
