Abstract
There is provided a method for manufacturing organic fertilizers by fermentation of a mixture of livestock excreement with cellulose containing organic materials, said mixture containing thermophilic and aerobic microorganisms, which method comprises adjusting moisture content of said mixture to 25-75 wt %, cutting and kneading said mixture until the temperature thereof goes up to 40.degree. C.-90.degree. C. by the elevated pressure and friction caused by said cutting and kneading, thereby causing thermophilic organisms to be activated, followed by pulverizing the thus-treated mixture while contacting it with air, thereby causing the aerobic organisms to be activated.
Claims2
Method for manufacturing organic fertilizers by fermentation of a mixture of livestock excrement with cellulose containing organic materials, said mixture containing thermophilic and aerobic microorganisms, which method comprises adjusting the moisture content of the said mixture, to 25%-75 wt %, cutting and kneading said mixture until the temperature thereof goes up to 40.degree. C.-90.degree. C. by the pressure and friction, in a primary treatment tank wherein a screw conveying system and a cutting/kneading system is provided, caused by said cutting and kneading, thereby causing said thermophilic microorganisms to be activated, followed by pulverizing the thus-treated mixture while contacting it with air in a secondary treatment tank, thereby causing aerobic microorganisms to be activated.
Method for manufacturing organic fertilizers by fermentation of a mixture of livestock excrement with cellulose containing organic materials, said mixture containing thermophilic and aerobic microorganisms, which method comprises adjusting the moisture content of said mixture, to a range of 25%-75 wt %, simultaneously adjusting the pH of said mixture with a pH adjusting agent in order that the pH value thereof during fermentation stays in a range of 6-9, cutting and kneading the mixture to elevate the temperature thereof to a range of 40.degree. C.-90.degree. C. by the pressure and friction, in a primary treatment tank wherein a screw conveying system and a cutting/kneading system is provided, caused by said cutting and kneading, thereby causing said thermoplastic microorganisms to be activated, followed by pulverizing the thus-treated mixture in contact with air in a secondary treatment tank, thereby causing aerobic microorganisms to be activated.
