A driven transporter screw, provided in the duct upstream of the microwave applicator, moves the dejecta material through the duct. An inlet, coupled to an upstream zone of the duct, feeds dejecta material to be treated into the duct adjacent the screw. A vapor extractor is coupled to duct immediately downstream of the irradiation zone to receive treated dejecta material immediately on leaving the irradiation zone. A condensation vat is connected to the extractor and vented through a chimney having a filter.Field of SearchUtilizing electrical or wave energy (directly applied to liquid or material being treated)Including drying (e.g., by squeezing or heating, etc.) And additional diverse separation And recirculating liquid Vapor or gas removal Diverse separators WITH GAS SEPARATOR Serially connected distinct treating or storage units Diverse Including a filter Plural separating | |
