  • Method and apparatus for agitating and intermixing aerobic thermophilical composting organic waste materials
    Patent number: 4377258
    Abstract: A method and apparatus for more efficiently agitating and intermixing organic waste material in a containing vessel includes a rotary cutting assembly which is vertically advanced downwardly into an accumulated quantity of organic waste material. The rotary cutting assembly separates an end portion of an accumulation of material from the remainder of the material and intermixes the separated portion with ambient air. The separated portion of material is then transported to a new location in the containing vessel.
