<p>PURPOSE:To smoothly propagate an yeast in its logarithmic propagation period and to improve fermentation efficiency by storing the CO2 generated when an org. waste is mixed with the yeast and fermented in an ageing chamber provided on the fermenter and communicating with the fermenter and bringing the stored CO2 into contact with the unfermented mixture for a specified time. CONSTITUTION:An impeller 3 is provided in the fermenter 1 for an org. waste, and an ageing chamber 4 for storing the carbon dioxide generated when the waste is mixed with an yeast and fermented is provided on the fermenter 1 and allowed to communicate with the fermenter. The waste and the yeast are charged into the fermenter 1, mixed, agitated and heated to the optimum fermentation temp. The agitation and heating are then suspended, and the mixture is brought into contact with the carbon dioxide stored in the ageing chamber 4 and allowed to stand for a specified time. After the yeast enters into the logarithmic propagation period, the mixture is kept at the optimum fermentation temp., agitated, fermented and then dried to obtain the fermentation product.</p> |
