汚染材料、特に病原菌で汚染した材料の処理方法

Japanese Patent JP4063891

B2

The invention relates to a method and device for treating contaminated materials, specially infected materials, which are fed to endless screws (5, 12) via a feed hopper (2) and are heated, disinfected or sterilized in addition to being discharged through an ejection system (21). The invention is characterized in that the materials are supplied to a first endless screw which is configured as a heating screw (5), wherein the material is also compacted in such a way that a sealing material plug (25) is produced at the end of said screw; the material is released into a treatment chamber (8) at the end of the heating screw (5) where it is expanded; the material in the treatment chamber (8) travels to a second endless screw which is configured as a treatment screw (12); burst of energy are introduced into the treatment chamber (8) into the treatment screw (12) in a controlled manner, steam is supplied or generated and an overpressure and the required temperature are produced and maintained and the material is compacted at the end of the treatment screw (12) into a second sealing material plug (26) so that the overpressure between both sealing material plugs (25, 26) of the screws (5, 12) can be maintained during a specific period of time. One advantage of the invention is that this method enables overpressure to be maintained between both high-sealing material plugs, which are continuously and automatically formed, over a long distance during a specific period of time.
