Novel Principles and Technical Solutions of Seeds Sorting

Abstract

The short analytical review of the existing methods and technical solutions of seeds sorting for justification of the choice of the most optimum ways of her implementation and assessment of its efficiency is submitted. Information on the novel principles of seeds sorting is provided: mechanical, pneumatic, electric, optical and x-ray and also data on serial samples (model, the producer) seeds sorters represented at Russian and the foreign markets. References to containing experimental data about sowing qualities and technological properties on the sorted fractions of seeds are given. For minimization of hit of standard seeds in screenings it is offered to use, on the basis of the analysis of publications of native and foreign researchers, the principle of preliminary fractionation, i.e. alignment according to the characteristics of seed material. The role of a method of X-ray radiography analysis as bases of industrial x-ray sorting of seeds and as the independent method allowing estimate quality of fractions of the seeds separated by other (electrical) methods is discussed. On the basis of the analytical review need of account several factors is proved at the choice of a method and technical solution of sorting: purpose of the separated batches, a species of a crop, initial qualitative characteristics of the separated batches of seeds, productivity of the equipment and cost of works on sorting. For assessment of its efficiency of sorting it is offered to use a complex of standard and additional methods of assessment of sowing qualities of seeds, for the purpose of more effective solution of a task of selection of the most suitable consignments of agricultural raw materials.
