Organic material reduction apparatus

Apparatus for the size reduction of vegetable and cellulosic material comprising a housing having opposite facing side walls, said housing including a first inlet opening in one of said side walls for introducing material into said housing, a discharge opening for discharging material from said housing, a drive shaft extending into said housing, impeller means connected to said drive shaft, said impeller means having opposite sides, shredding means connected to said drive shaft and being disposed between one side of said impeller means and said first inlet opening for shredding material passing into the housing through said inlet opening and reducing the size of the material, said housing including a second inlet opening in the other of said side walls for introducing material into said housing, said inlet openings introducing material into said housing from said opposite side walls with components of movement along said drive shaft in opposite directions, and chipper means disposed between the opposite side of said impeller means and said second inlet opening for chipping material passing into the housing through said second inlet opening, said impeller means forcing material from said shredding means and said chipper means toward said discharge opening.

Apparatus for the size reduction of vegetable and cellulosic material comprising a housing, said housing including a first inlet opening for introducing material into said housing and a discharge opening for discharging material from said housing, a drive shaft extending into said housing, impeller means connected to said drive shaft, said impeller means having opposite sides, shredding means connected to said drive shaft and being disposed between one side of said impeller means and said first inlet opening for shredding material passing into the housing through said inlet opening and reducing the size of the material, said housing including a second inlet opening for introducing material into said housing, and chipper means disposed between the opposite side of said impeller means and said second inlet opening for chipping material passing into the housing through said second inlet opening, said impeller means including a backing plate at said opposite side thereof, said plate having an opening formed therethrough adjacent said chipper means for receiving chipped material from the chipper means so that the chipped material may pass through said opening in the plate to be forced outwardly by the impeller.

Apparatus for the size reduction of vegetable and cellulosic material comprising a housing, said housing including a first inlet opening for introducing material into said housing and a discharge opening for discharging material from said housing, a drive shaft extending into said housing, impeller means connected to said drive shaft, said impeller means having opposite sides, shredding means connected to said drive shaft and being disposed between one side of said impeller means and said first inlet opening for shredding material passing into the housing through said inlet opening and reducing the size of the material, said housing including a second inlet opening for introducing material into said housing, and chipper means disposed between the opposite side of said impeller means and said second inlet opening for chipping material passing into the housing through said second inlet opening, screen means disposed outwardly of said impeller means so that material passing radially outwardly from said impeller means impinges upon said screen means, said screen means being supported by said housing for movement toward and away from said impeller means during operation of the apparatus to prevent clogging of material between said impeller means and said screen means.
