METHOD OF POULTRY MANURE DIGESTION INTO FUEL BRIQUETTES Russian patent published in 2016 - IPC C10L5/44 C10L5/46 C10L5/00 A01C3/00 

FIELD: agriculture.

SUBSTANCE: invention discloses a method of processing poultry manure into fuel briquettes involving preliminary preparation of components of the initial raw material, dosing of each component, initial raw material milling, mixing in a forced-type mixer to produce a homogeneous mass, the prepared mass is fed into a loading hopper of a piston press, where the mass sealing and moulding the shape and length of briquettes are performed, further drying of the briquettes, herewith the initial raw material milling is performed after its mixing in the mixer, before feeding for briquetting, moisture content of the produced after milling mass is measured and depending on its value pressure of moulding the briquettes is selected from the range of 0.2-1.0 MPa, drying of the briquettes is performed within the temperature range of 50-100 °C in three stages with different exposure time at each stage, herewith at the first stage at the temperature of 50-60 °C during 20-40 minutes, at the second stage at the temperature of 75-85 °C during 3-4 hours, and at the third stage at the temperature of 80-100 °C during 50-70 minutes, then the briquettes are cooled to 40-30 °C naturally or in the forced manner.

EFFECT: technical task of the invention is obtaining fuel briquettes with high calorific value.
