METHOD OF PRODUCTION OF ORGANIC FERTILISER AND FEED ADDITIVES BASED ON RESIDUAL PRODUCTS OF PROCESSING OF FISH SCRAPS Russian patent published in 2013 - IPC C05F9/00 C05G3/00 

FIELD: agriculture.

SUBSTANCE: method of production of organic fertiliser and feed additives based on residual products of processing of fish scraps, in which a mixture of any fish scraps is crushed and milled to fractions with the diameter no more than 2-3 mm, the preparatory process is performed, comprising uniform mixing, thermal heating for not more than 5 hours at a temperature of 80°-90°C, cooling to a temperature not lower than 45°C, maintenance of humidity of the mixture not lower than 75%, then the process of anaerobic fermentation in the reactor at an optimal temperature of 60°C is carried out. At that in the fermentation process once the temperature jump to 105°C for 15-20 min is provided, the phosphoric acid solution and the enzymes of biological nature are added, the final product after the fermentation is subjected to separation of the liquid component and the biological sludge (centrifuge effluent), a mixture of low molecular weight fatty acids is added to the final paste granulate.

EFFECT: invention enables to improve the quality of the final product, to expand the range of products produced, to improve the environmental and sanitary conditions of production.
