<p>The purpose of the present invention is to provide a multistage organic matter drying system which achieves easy overall temperature control, high heat utilization efficiency, and the prevention of the flow rate of superheated steam from becoming excessively high even when a low-temperature heat source is used. A multistage organic matter drying system which is provided with a conveying means for conveying organic matter to multiple stages (4) from an upper stage to a lower stage, and a drying chamber (1) housing the conveying means, and sends superheated steam (a-c) into the drying chamber to dry the organic matter is characterized by comprising N (N is a natural number larger than or equal to 2) lead-in ports (21-23) for leading the superheated steam into the drying chamber, and N±1 lead-out ports (31, 32) for leading the superheated steam out of the drying chamber.</p> |
