EVALUATION OF THE EFFECTIVENESS OF UNIFIED CLEANING AND DRYING COMPLEXES
Abstract
There is given gradation of conditions of postharvest grain processing at Siberian agricultural enterprises, due to three groups of natural areas: without drying of grain harvested (grain moisture of below 15 percent), single-time drying (grain moisture of 15 to 21 percent), and two-time drying (grain moisture of 21 to 27 percent). Enterprises of the first group of zones should be equipped with grain cleaning units, those of the second and third groups of zones with grain cleaning and drying complexes. Based on the volume of grain to be processed and performance of available machinery, four sizes of units and complexes with capacities of 100, 200, 400 and 800 tons of grain a day were established. With regard to the second group of zones, technological schemes for various combinations of conditions of postharvest grain processing were developed, and technical and economic parameters of variants of grain cleaning and drying complexes were determined. It has been found that when the capacity of the complex makes up 100 tons of grain a day, it is preferred, from the point of view of operating costs, to process grain by the flow line method; this requires certain additional investment. In case of investment resources deficit but the sufficient number of employees, an enterprise can use grain stocking at the processing ground. When using complexes with capacities of 200, 400 and 800 tons a day, a variant of grain processing with storing it in the operating silo is preferred. In case of manpower deficit but availability of extra capital investment, an enterprise is recommended to use the flow-line grain processing technology by means of the complex with the capacity of 200 tons of grain a day. If an enterprise lacks financial resources but has the sufficient number of employees, the scheme of grain processing, followed by its reservation at the covered area, should be used.
