发明名称 Sludge dehydrater having specially designed augers and infrared heater elements
摘要 The invention discloses an apparatus and process for destroying pathogens and dehydrating streams of waste in one, continous process. More particularly, the invention contains an auger with specially modified, variably angled blades which agitates a stream of waste. Also, contained in tandem with the auger, a series of variably angled infrared radiate elements are positioned above the augar exposing the moving stream of waste to radiation. Thus, as the waste stream is transported along, the auger blades continually expose the waste stream to the radiation, thereby killing the entrapped pathogens and evaporating the insitu water. Further, the auger and infrared radiation heater elements are encased in a sealed trough, thus sealing in the heat being generated by this process. By sealing the trough, the heat provides excess energy to aid in destroying pathogens and evaporating the insitu water contained in the waste stream, until the water content is less than or equal to five per cent (5%) by unit volume.
