FERMENTED FERTILIZER COMPOUND WITH 'SHOCHU' LEES AND POULTRY MANURE, ITS PRODUCTION AND PREVENTION OF POLLUTION OF 'SHOCHU' LEES AND POULTRY MANURE

摘要

PURPOSE:To obtain a fermented fertilizer having improved quality by properly compounding SHOCHU (low-class distilled spirits) lees and poultry manure as main raw materials and subjecting to exothermic fermentation in a fermentation tank while keeping the water-content and temperature at respective specific levels by repeating water-sprinkling and stirring procedures. CONSTITUTION:SHOCHU cake usually containing 90-100wt.% of water and poultry manure mixed with wood chips and having a water-content of 20-30wt.% are charged into a fermentation tank at a ratio of 1/3 to 3/1 and inoculated with aerobic fermentation bacteria. The mixture 4 of the SHOCHU lees and poultry manure is stirred with a rotary blade attached to the lower end of a stirrer 3 placed in a state extended between rails 2 laid on the edges 1 of the fermentation tank. The mixture is sprinkled with water while inspecting the fermentation temperature to keep the water-content to 50-70wt.% and the temperature to 55-75 deg.C. The stirring and the water-sprinkling procedures are repeated for a prescribed period until the completion of fermentation is ascertained by the lowering of the temperature. The mixture 4 is taken out of the tank, transferred to a separate place and allowed to cool by turning over twice or thrice to evaporate excess water and obtain the objective fermented fertilizer.
