NOVELTY - The tobacco solid waste material comprising waste stalk material, bug dust, fine tobacco leaf, moldy waste and un-graded tobacco leaf is soaked in water for 12-24 hours, solid-liquid separated, dehydrated and dried. The raw material is fed to carbonizing chamber. Crops stalk is added and heated. The mixture is carbonized at 200-380 degrees C for 4-8 hours. Water is added and mixed. The mixture is sent into module for extrusion forming, to prepare hydrous shaped charcoal. The hydrous shaped charcoal is dried and cooled to obtain charcoal products.    USE - Usage of tobacco solid waste material for preparing shaped charcoal.    ADVANTAGE - The charcoal products is simply, stably, economically and safely manufactured by treating solid waste material.    DETAILED DESCRIPTION - The tobacco solid waste material as raw material comprising waste stalk material, bug dust, fine tobacco leaf, moldy waste and un-graded tobacco leaf is soaked in water for 12-24 hours, solid-liquid separated and dehydrated. The solid waste material is comprehensively or non-comprehensively used in extracting solanesol and nicotine. The dehydrated material is dried, such that moisture content is 10-20%. The pre-treated raw material is continuously fed to feeding opening of carbonizing chamber at speed of 60-120 cm/hour. The raw material is driven forward at rotating speed of 0.5-3 revolution/minute through carbonizing chamber. Crops stalk is added to combustion chamber provided below carbonizing chamber, and heated. The mixture is continuously carbonized at 200-380 degrees C for 4-8 hours. The carbonized material is continuously discharged from discharging opening of carbonizing chamber provided opposite to feeding opening of carbonizing chamber. Water is added in weight equivalent of 0.5-1 time of carbonized material, and uniformly mixed. The mixture is sent into module for extrusion forming, to prepare hydrous shaped charcoal. The hydrous shaped charcoal is dried at 100-110 degrees C for 1.5-3.5 hours, and cooled to room temperature to obtain the shaped charcoal products. The crops stalk is rice straw, wheat straw, sorghum stalk or cornstalk.
