CONFIGURATION OF THE BASIC SCHEME OF CLEANING MACHINES IN THE TECHNOLOGICAL FLOW OF SEED CONDITIONING FOR AGRICULTURAL CROPS AND MATHEMATICAL MODELING OF THE CLEANING PROCESS

Abstract

The quality of seeds, designated as biological material for the establishment of new crop generations, is largely determined by their physical characteristics, achieved through conditioning and preservation. Proper exploitation equipment and configuration of cleaning machines in the technological seed conditioning flow include: number of cleaning machines (z), optimal feeding rate (q), combinations of sieves with different hole types (g) used in a single operation, as demonstrated in this article, can ensure the final quality of wheat seeds belonging to the biological category of the batch while also contributing to energy saving. Through utilization of well-known statistical techniques it was possible the interpretation of results, which highlighted significant differences between cleaning machines variants regarding technological flow, which affected in the final the most important parameters of seeds like purity (Ƥ) and germination (G) but also the seed technical processing efficiency ( Ƞ????????????????). By using the active experimental planning method (AEPM) and the orthogonal central composite design (OCCD) of the second order, a multidimensional mathematical model Ƥ = f (q, g, z), was developed to describe the efficiency of conditioning process.
