Homogeneity of granular mixtures was studied by using fluorescence tracers to evaluate the application of the method for multicomponent mixts. A 15-component feed mixt. was use for the study. Maize and safflower seeds were coated with soins. of fluorescent substances (tinopal 0.3%, uranine 0.3% and 0.5%, rhodamine 0.01%) and introduced into the feed. The fluorescence-based methods can be recommended for the assessment of homogeneity of multicomponent granular mixts.
