INVESTIGATION OF TECHNOLOGICAL PROPERTIES OF FOUR-TYPE TRITICALE SEED OF DIFFERENT FRACTIONS

Abstract

Triticale is a promising agricultural crop. The increased content of protein, balanced by the amino acid composition, advantageously distinguishes triticale seed for peeled grains and food concentrates production. Seed cleaning is an important technological operation of food productions, but setting regimes of seed-cleaning equipment for processing triticale seed need specification today. The aim of this work is to study geometric and physical characteristics of four-type triticale seed and elaboration of recommendations as to its cleaning and fractionating. There was studied the fractional composition of four-type triticale seed. The comparative analysis of its length, width and thickness in samples of different sorts and fractions was realized. The dependence of geometric properties of triticale seed on sort is reliable. Fractionating reliably influences the change of the mass index of 1000 seeds, changing from 65,2 g to 25,8 g. The mass index of 1000 seeds essentially differs between studied sorts. Such properties are inherent to seed fractions, obtained by a sieve of 3,2–20 mm and 3,0–20 mm, that are recommended to be called big seeds. Fractions, obtained by a sieve of 2,0–20 and 2,2–20 are analogously similar. Properties of the middle fraction, obtained by sieves of 2,4–20; 2,6–20; 2,8–20 essentially changed, depending on sort. The elaborated recommendations may be used at choosing cleaning regimes for triticale seed on sieve and sieve-air separators.
