METHOD OF PRODUCTION OF FEED ADDITIVE OR FERTILISER FROM HYDROBIONTS Russian patent published in 2014 - IPC A23K1/00 

FIELD: agriculture.

SUBSTANCE: method comprises mixing, grinding, heat treatment and drying of fish raw material and algae or waste of their processing to the residual moisture weight ratio not exceeding 10%. The fish raw material is used as collagen-containing fish wastes. Mixing and grinding of raw materials is carried out in a container with rotating blades. First fish scales are processed, drying it to the residual moisture weight ratio not exceeding 10%, then the remaining collagen-containing fish wastes and algae or wastes of their processing are added in an amount such that the weight ratio of the scales in the mixture is not less than 50%. Processing of the mixture is continued at high speed mode of blade rotation, providing heat treatment and drying of raw material due to the release of the heat at friction and generated air flows. Organic matter vapours released during drying are removed to the filter, which is used as algae.

EFFECT: invention provides obtaining feed additive or fertiliser at lowest costs.
