METHOD FOR PRODUCTION OF ORGANOMINERAL FERTILIZER BASED ON CHICKEN MANURE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2020 - IPC C05F3/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used for production of fertilizer based on chicken manure. Method of preparing organomineral fertilizer involves adding fresh lard-free chicken manure with moisture content of 50–55 % of quicklime in proportion of 15–25 % of the weight of chicken manure with stirring during 45–60 minutes at 15–30 rpm. Method then includes aeration, removal of ammonia-air mixture and holding mixture for 0.5–2.5 h to achieve pH 6.0–8.5. Method is implemented by means of a device for preparation of organomineral fertilizer, which includes a hopper-reactor with shafts for mixing and supply, which is connected through a screw conveyor with a stationary mixing hopper and / or with a mobile hopper. Bunker-reactor is connected with air supply device and device for discharge of gas-air mixture supplied to tank with water, in upper part of which there is unit for selection of gas saturated with gases, including ammonia. Container with water is connected to the water supply device, and the hopper-reactor is connected to the granulator connected to the packing unit.

EFFECT: reducing the process of processing poultry manure to produce organic fertilizer of high quality and ammonia water used as nitrogen fertilizer.
