Fermentation drying of plant Characteristic organic matter/preliminary carbonization/calcination manner, fermentation drying of plant Characteristic organic matter/preliminary carbonization/calcination device, hot fermentation microbial group and fermentation dry material
PROBLEM TO BE SOLVED: To change a powdery/granular or crushed state vegetable organic substance to an excellent fermented dried raw material for a carbonaceous material, by oxidatively fermenting the vegetable organic substance with aerobic thermophilic fermentative bacteria to dry it, fermentatively decompose oil, and depolymerize fibrous material or the like by fermentation. ;SOLUTION: Thermophilic fermentative bacteria are added to a powdery or granular vegetable organic substance 2 accommodated in a mixing preliminary fermentor 1, and both are mixed and stirred by an impeller type mixer 3. At this time, some fermentation dryness has already been begun, and the transpiration of moisture by the fermentation heat also starts. To accelerate the preliminary fermentative drying and to further accelerate the transpiration of moisture, a pipe 5 which circulates heat by utilizing exhaust heat from a preliminary carbonization tank is passed through the bottom wall of the mixing preliminary fermentor 1 to warm the vegetable organic substance 2. Therefore, the fermentative drying is carried out by using the degrees of dryness, decomposition, and depolymerization as indices. Thereby, a good quality fermented dried material can be surely obtained.;COPYRIGHT: (C)1999,JPO
