  • Patent number: 6790349
    Abstract: A waste treatment apparatus for the treatment and processing of wet material is provided. The apparatus comprises an inlet hopper adapted for receipt of the wet material. A pre-conditioning unit is provided having an input and an output end wherein the wet material is received from the inlet hopper at the input end and is conveyed to the output end wherein the wet material is processed to reduce moisture and pathogen content. A blower is provided for providing a forced air stream to direct the flow of the wet material and for directing the flow from the output end of the pre-conditioning unit. A pre-separation cyclone is provided and is operatively positioned for receiving the wet material from the output end of the pre-conditioning unit via the air stream powered by the blower, wherein the wet material is processed under the influence of cyclonic forces that further reduce the moisture content, pathogen content, and reduce the particle size of the wet material.
