PRODUCTION OF ORGANIC FERTILIZER AND FEEDING STUFF BY WASTE CHICKEN DISCHARGED FROM POULTRY FARM

摘要

PURPOSE:To change waste into the resources and to improve environmental sanitation by pulverizing a waste chicken, adsorbing and mixing the pulverized chicken to/with bran, etc., and granulating the mixture and performing aerobic fermenting treatment and then drying the granules. CONSTITUTION:A waste chicken discharged from a poultry farm is pulverized with a chopper directly or after boiling it and the pulverized material is obtained. Then the material is adsorbed and mixed to/with chicken droppings, bran and wheat bran, etc., and this mixture is granulated. Thereafter aerobic fermenting treatment is performed at about 60-70 deg.C by utilizing a fermentation equipment. Finally drying treatment is performed to regulate its water content to =30% and thereby the title organic fertilizer is obtained. When the chicken droppings are not utilized in the above-mentioned granulating stage, aerobic fermenting treatment is performed at about 60-70 deg.C by utilizing the fermentation equipment after granulation and finally drying treatment for regulating the water content to =30% is performed and thereby the title feeding stuff is obtained.
