NOVELTY - A solid state fermentation equipment comprises fermenter, active carbon absorbing pillar, receiver, gas holder, carbon-dioxide gas bottle, gas stripping pot, condenser, step motor, alcohol concentration measuring apparatus and air pump. The fermenter is equipped with spiral propeller, feeding device airlock, cross-lying port which is vertically connected to gas stripping pot. The step motor is electrically connected with spiral propeller in fermenter, and at least two of active carbon absorbing pillar (A,B) are positioned and equipped with electric heating device.    USE - Solid state fermentation equipment is used for producing alcohol using sugar grass straw (claimed).    ADVANTAGE - The solid state fermentation equipment is efficient, and economically provides alcohol.    DETAILED DESCRIPTION - A solid state fermentation equipment comprises fermenter, active carbon absorbing pillar, receiver, gas holder, carbon-dioxide gas bottle, gas stripping pot, condenser, step motor, alcohol concentration measuring apparatus and air pump. The fermenter is equipped with spiral propeller, feeding device airlock on shell, cross-lying port which is vertically connected to the gas stripping pot. The outside of fermenter and gas stripping pot are equipped with water cooling jacket. The step motor is electrically connected with spiral propeller in fermenter, and at least two of active carbon absorbing pillar (A,B) are positioned. The outer side of active carbon absorbing pillars is equipped with electric heating device. The lower terminal port of gas stripping pot is connected to carbon-dioxide gas bottle via carbon-dioxide recycle gas pipeline, and also connected with compressor and gas holder. The upper terminal port of gas stripping pot is respectively connected to lower portion of active carbon absorbing pillar (A) and active carbon absorbing pillar (B) via pipeline. The pipeline is equipped with alcohol concentration measuring apparatus (A), and the two active carbon absorbing pillars (A,B) are installed in parallel. A switching valve (A) is installed in lower terminal port shunt-wound pipeline of the active carbon absorbing pillar (A), and the active carbon absorbing pillar (B). A switching valve (B) is installed in the upper terminal port shunt-wound pipeline of the active carbon absorbing pillars (A,B), and connected with gas pipeline. The gas pipeline is connected with in order of alcohol concentration measuring apparatus (B), condenser and receiver. The upper portion of active carbon absorbing pillars (A,B) is respectively connected with pipeline via triple valve. The end terminal of pipeline is connected to gas holder, and the lower terminal ports of active carbon absorbing pillars are respectively connected to air pump with air pipeline.
