METHOD FOR PRODUCTION OF FULL RATION COEXTRUSION FEEDSTUFFS FOR FUR ANIMALS Russian patent published in 2011 - IPC A23K1/00 

FIELD: food industry.

SUBSTANCE: invention relates to production of feedstuffs for fur animals, in particular MINKS. The method for production full ration coextruction feedstuffs envisages preparation of a mixture of wheat grains and rapeseed cake (preliminarily milled for particle size to be 0.6…1.2 mm, addition of meat meal, a premix and food chalk to the mixture at a specific ratio of components, moistening for humidity to be 16…18% and maintenance for 4 hours in a bin for humidity levelling across the mixture bulk. Then one proceeds with the mixture treatment in a worm extruder, the product temperature before the matrix being 393…413 K, the worm rotation rate equal to 5…7 s^-1 while pressure in the extruder pre-matrix zone 7…9 MPa. Before the mixture discharge from the extruder one injects a fat-vitamin-mineral filling into the central part of the extrusion strap in an amount of 15% of the initial pressure weight. For the filling preparation one mixes fodder animal fat, deodoration cut-back products, fodder lysine and fodder methionine at a specific ratio of components.

EFFECT: invention enables production of a full ration feedstuff noted for high nutritional properties and biological value, expansion of the range of available foodstuffs balanced in terms of nutritional value and storage life extension.
