Experimental Device for Improved Cleaning and Calibration of Maize

Abstract

All seed raw materials are cleaned from impurities from the mass, as well as spoiled. To obtain high-quality seed material, they need their main characteristics — size (width, length, thickness), weight, aerodynamic properties, etc. are sorted by in many modern grain cleaning machines, sorting is performed simultaneously with cleaning. Although there are state standards for seed marriage, quality control is often not carried out at the proper level by the control service. In this regard, there is an increased demand for cleaning and sorting machines. Analysis of the designs of existing seed cleaners and sorting equipment shows that the most promising in terms of research are devices with working bodies made in the form of flat sieves and regular vibration exposure. Taking into account the urgency of the issue, this research work is aimed at constructive and technological improvement of the technology and sorting device at the stage of selection of corn grain intended for sowing.
