Approaches to improving the grain quality control system at elevators

Бесплатный доступ

The production process at elevator complexes is considered, one of the main tasks of which is the formation of batches of grain with specified quality indicators. An important place is given to the control system of physical and chemical-biological indicators of grain, standardized by GOST 9353-2016: mass fraction of protein; quantity and quality of gluten; falling number; vitreousness; nature; humidity; the content of weed and grain impurities. The applied control system, instrumentation, measurement methods are imperfect, long in time and focused on outdated devices. used on elevators. The methods of laboratory studies of grain do not allow them to be integrated into the technical process of controlling modern machines and devices in the "on-line" mode. Problems in determining grain debris and moisture content are described. As a result of the analysis of the current state, directions for improving the grain quality control system are proposed. One of the ways to reduce the time for laboratory analysis of grain is the use of devices that use the method of NIR spectroscopy in their work. The instrumental base of spectral analysis is infrared analyzers and spectrophotometers. They allow you to quickly determine the parameters: fat, protein, starch, moisture content, ash content. The advantages of infrared analyzers of grain quality include: a significant reduction in the time for analysis; significant energy savings; devices do not require the use of expensive consumables and chemicals; less stringent requirements for special training are imposed on service personnel performing measurements. The scope of application in world practice of infrared analyzers for analyzing the quality of agricultural products is shown, their advantages are described
