System for Analyzing the Qualitative Characteristics of Grain Mixes in Real Time Mode

Abstract

During the implementation of scientific research on the direction of automation of feed mills there was a significant disadvantage. The losses resulting from this shortcoming are, according to our estimates, about 1.2 billion hryvnias per year only within the framework of Ukraine. The disadvantage is connected with the current system of techno-chemical control. The presence of significant delays in the channel analysis of qualitative characteristics leads to the loss of the possibility of using the information obtained in the work of the automatic control system. The developed system of automatic samplers allows to minimize the time for obtaining actual data on the qualitative characteristics of grain mixtures directly during their processing and accordingly expands the possibilities of automation of these processes. Existing systems of analysis of grain characteristics in real time, i.e. directly during the process of processing, are quite costly, which greatly complicates the possibility of constructing an expanded system for analyzing the quality of raw materials at all stages of production. In addition, the integration of these analyzers requires the production of serial installation work on the production line, and accordingly requires for the installation of a temporary stop of production. The installation of stationary multispectral analyzers requires the presence and, accordingly, further maintenance of a full-fledged laboratory. However, the essential disadvantage in this case is the lack of relevance of the data. Thus, when using stationary multispectral analyzers, the data obtained only records the logs and in no way are used by systems of automatic process control at the enterprise. In a sublunary manner, analyzers have been tightened due to the separation of two different processes in principle, which are to be in the multispectral analysis, namely, the process of removing the multispectral sweep and analyzing the resulting scan with the aim of determining specific quality characteristics of the grain mixtures. Thus, in some devices, the sweep is taking place, and their analysis is already taking place in a single multispectral analyzer, which in turn is connected to cloud technologies.

Design development of a continuous industrial drying plant for drying pomace of walnuts, peanuts and pistachios

“…The theoretical and experimental studies made it possible to obtain empirical relations [15,16] necessary for the engineering calculation of the design features of a dryer with a fluidized bed of an inert drying carrier. Fig.…”

Improvement of equipment in order to intensify the process of drying dispersed food products

“…Another effective way to reduce the cost of a dried product is intensification of the drying process through the effective use of a drying chamber. The intensification of the drying process is associated in work [9] with an increase in the phase contact surface. By increasing the relative speed of the dispersed and gaseous phases, the authors increase the driving force of the drying process and reduce the heat-carrier consumption for drying.…”

Development of a technique to control and ensure the predefined porosity of a grain layer in the pneumo-separating channel at a grain heap cleaner

“…Chemical analysis of grain in real-time involved cheap sensors, which operate on the basis of spectral analysis. Such sensors have been designed for grain separators [13], as well as to analyze a grain heap from a harvester [14]. However, still unresolved are the tasks associated with using such sensors to operate PSC.…”
