NOVELTY - Device comprises a liquid ammonia steel bottle (1), an ammonia reducing valve (2), a stainless steel valve I (3), a blasting cylinder (4), a clamping sleeve (5), a stainless steel valve II, a collecting tank, an exhaust pipe, a pressure gauge, a thermometer and a blasting frame. The liquid ammonia steel bottle is connected with one end of the blasting cylinder through the ammonia reducing valve and the stainless steel valve I, and the other end of the blasting cylinder is connected with the collecting tank through the stainless steel valve II.    USE - The device is useful for preparing alcohol by using liquid state medium blasting lignocellulose raw material.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing alcohol by liquid state medium blasting lignocellulose raw material using the device, comprising: (i) preparing the blasting lignocellulose raw material by: (a) adding (in parts by wt.) lignocellulose material (20-150), liquid ammonia medium (10-300) or other medium solution (10-300) with a concentration of 0.1-1.1 mol/l into the blasting cylinder (4), heating and blasting; (b) switching on the power of the electric heating pipe or the steam heating pipe connected to the clamping sleeve (5), heating the liquid ammonia at 40-100 degrees C with a heating speed of 20-40 degrees C/minute, increasing the pressure up to 0.5-5 Mpa, maintaining the liquid ammonia blasting time for 20-60 minutes, or heating the other medium solution with the concentration of 0.1-1.1 mol/l at 150-270 degrees C with the pressure of 0.5-5 Mpa, maintaining the blasting time of other medium solution for 2-30 minutes, adding the blasting material into the collecting tank (7) through the stainless steel valve II (6), drying the blasting material at 50-105 degrees C for 6-24 hours, and detoxifying; (ii) preparing alcohol by blasting lignocellulose raw material: (A) adjusting the blasting material by a citric acid buffer solution (pH 4.8-5) to have the weight ratio of the dry material to the water of 1:(8-12), adding composite saccharifying enzyme (200-250 filter paper unit (FPU)) based on each gram of the dry material, and saccharifying 45-55 degrees C for 20-28; and (B) adding the yeast based on the inoculum size of 16% of the total fermentation substance, and performing fermentation at 32-42 degrees C for 3-5 days to obtain the fermentation liquor with the alcohol content of 0.5-5%.
