Abstract
An apparatus for converting unconsolidated medical waste into a non-hazardous medical waste residue, which apparatus has an improved cutter assembly provided by a rotating cutter assembly that has revolving teeth disposed at an oblique angle relative to the path of travel of the revolving teeth and to the stationary cutter assembly to force the waste material between the revolving and fixed teeth. An auger moves the waste material through the housing longitudinally to keep pressure on the opposing fixed and revolving teeth while grinding the material into a reduced particle size to facilitate its disposal or storage.
Claims8
An apparatus for converting unconsolidated medical waste into a sterilant non-hazardous medical waste residue, comprising a first revolving cutter assembly having revolving teeth which interfit and co-act with first non-revolving fixed teeth on a stationary cutter assembly, said revolving and fixed teeth having a radial gap therebetween for receiving the medical waste, the improvement comprising:
- each revolving tooth having a substantially pointed cutting surface which lies in its plane of rotation and is disposed at an oblique angle to its path of rotation and is inclined inwardly towards the center in the direction of rotation and relative to the stationary cutting teeth to engage the medical waste and apply a powerful shredding force on the waste material therebetween as each revolving tooth enters and moves through the radial gap between the revolving tooth and the valley between each pair of fixed teeth adjacent and opposed to each revolving tooth.
