NOVELTY - A continuous solid fermentation process for production of fuel ethyl alcohol, comprises: (a) adding bacterium: adding a fermentation bacterium into a crushed material, and feeding the crushed material into a continuous solid fermentation tank; where the inoculum size of the fermentation bacterium is 5-20% (v/w); and (b) carrying out continuous solid fermentation: fermenting the crushed material to convert the fermentable saccharide into ethyl alcohol for 30 hours at speed of 0.03-0.4 rotations/minute; where the temperature in the continuous solid fermentation tank is kept at 30-36 degrees C.    USE - The continuous solid fermentation process is useful for production of fuel ethyl alcohol (claimed).    ADVANTAGE - The continuous solid fermentation process makes full use of the fermentable saccharide in straw by continuous solid fermentation; thus, avoiding usage of preservative and improving the yield of ethyl alcohol. Moreover, the process changes the traditional production method by using a continuous solid fermentation device; thus, carrying out a continuous solid fermentation process. Additionally, the revolving speed of the fermentation tank and the angle of the shoveling plate are adjustable; thus, the adjustability and controllability of the product are improved.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is a continuous solid fermentation device for production of fuel ethyl alcohol, comprising a feeder (1) that is connected with the closed cabin (10); where the closed cabin (10) is set with a material level meter (2) and a bacterium liquid spray tube (3); a double-roll feeder (11) is mounted at the exit of the closed cabin; the exit of the double-roll feeder (11) is connected with a spiral feeder (12) that extends into a feed closed cabin (13) and fixed in it; the feed closed cabin (13) is connected with the continuous solid fermentation tank (5) in a mechanically sealed manner; the continuous solid fermentation tank (5) is arranged at an angle of inclination along the axis toward the exit; a toothed ring (6) is fixed on the outer wall of the tank; a speed changer drive device (15) is engaged with the toothed ring (6) to drive the continuous solid fermentation tank (5) to revolve under the support of a riding wheel (16); the exit of the continuous solid fermentation tank (5) is connected with a closed discharge cabin (7) that is set with an exhaust port (8) and a respiratory valve (9); the closed discharge cabin (7) is connected with the continuous solid fermentation tank (5) in a mechanically sealed manner; a gate valve (18) is mounted at the exit of the closed discharge cabin (7); and the closed discharge cabin is sealingly connected with the following equipment via the gate valve (18).
